ECU (system electronic control Sustainability). See ESC
ESC (Electronic Stability Control) - electronic control of stability.
ESP ® (Electronic Stability Program) - Program electronic stabilization Bosch. See ESC.
ABS (Anti-Lock Braking System) - Anti-lock system
Automated system Preventing the wheel blocking in case of braking. The main task of the system is to ensure manageability vehicle with sharp braking.
ASR (Antriebs Schlupf Regelung) - Anti-slip system (APS)
Logical continuation of the development of the ABS anti-lock system. This system will significantly simplify the control of the car on a wet or raw track. See TCS.
TCS (Traction Control System) - Anti-Personal System / Traction Control System
Electro-hydraulic car system designed to prevent loss of thrust by controlling the protrusion of leading wheels. Activated with the propensity of one of the leading wheels to slip.
Bas (Brake Assist System) - Amplifier emergency braking
The system is designed to help with extreme braking. Works in conjunction with ABS and EBD systems. The system is assessed at what speed the brake pedal was pressed, other sensors fix the wheel rotation speed and vehicle speed. If the speed is large and the brake pedal is pressed very quickly, then the BAS system makes the brakes on the full power, but without blocking the operation of ABS.
HSA (Hill Start Assist) - System of helping when rising
It facilitates the start by maintaining the brake pressure for about 2 seconds after the brake pedal is released. The driver has enough time to transfer legs from the brake pedal to the gas pedal without use manual brakes. The car quietly rides, not rolling back, which is much enhanced by the comfort and safety of driving.
TPMS (Tires Pressure Monitoring System) - Tire pressure control system
Designed to prevent a dangerous change in tire pressure. A drop in tire pressure entails a change in the angular velocity of the wheel. By comparing the speeds of rotation wheels, a potentially blown wheel is detected. This additional feature allows you to monitor tire pressure without using tire pressure sensors.
HBA (Hydraulic Break Assist) - Hydraulic braking amplifier
The hydraulic brake amplifier recognizes the threat of emergency braking, controlling the position of the brake pedal and the pressure gradient. If the driver slows down enough, then the brake hydraulicer increases the braking force to the maximum. The brake path is reduced.
EBD (ELECTRONIC BRAKE DISTRIBUTION) - Electronic brake force regulator
The brake force distribution system is designed to prevent the rear wheels by locking the brake force control. With a sharp braking of the car, an additional reduction in the load on the rear axle occurs, as the center of gravity is shifted forward. And the rear wheels, at the same time, may be blocked.
Questions and answers
Why am I Esc?
At least 40% of all deaths in the accident - the result of the drift. Studies have shown that ESC can prevent up to 80% of all accidents occurring due to driving.
What is the difference between ESC and ESP®?
The principle of operation and the effect of all dynamic stabilization systems in terms of traffic safety is the same. The difference is only in the name and data producer of systems.
How does ESC work?
The ESC uses a number of "smart" sensors that fix the loss of control. The system with a frequency 25 times per second compares the target-specified path with the actual. When they are misappropriated, and if the car becomes uncontrollable, the ESC is triggered. The engine power decreases to restore the resistance of the car. If this is not enough, the system additionally slows down the individual wheels. The resulting rotary movement of the car opposes the drift. Within physical abilities, the car maintains coursework stability.
Is it possible to save the car by the ESC system?
Not. ESC cannot be installed on the machine where it was not. Therefore, when buying a car initially, take the right solution.
Do you need to turn on ESC when starting the engine?
Not. With the engine running, the system is always active. Some models are equipped with the ES switch. When you click on it, as a rule, TCS is deactivated (anti-test brake system), while the features of the electronic stabilization program are saved. Disconnection is indicated by the control lamp on the instrument panel.
Do I need to change the driving style when driving a car with ESS?
Not. No driving style is required. Espostu supports the driver in critical situations - in the threat of driving. However, you must always be attentive and abide by the road.
Is anti-lock (ABS) and anti-test systems (TCS)?
ESA combines all ABS and TCS components, with additional advantage is the dynamic stabilization of the car. Preventing wheel blocking, ABS retains car handling in case of emergency braking. TCS prevents wheel strokes with sharp acceleration, providing optimal cravings. While ABS and TCS work in the longitudinal direction, ESC helps counteract the side offsets leading to the drift.
The skid is one of the main causes of heavy traffic accidents. The wet road surface, an unexpected steep turn or suddenly appeared on the road, an obstacle forcing the driver to a sharp maneuver or braking significantly increase the danger of breaking into a skid. And this applies even to experienced drivers.
It is responsible for the course stability of the car, preventing its side slip, breaking into a skid and rotation, when the driver due to a lack of time or experience cannot perform the desired maneuver independently. As a result, the car always remains on the chosen trajectory driver.
The ESC system combines ABS and TCS functions, and in addition, ensures control of the resistance of the car. The system helps the driver in any road situation. It determines the risk of tipping and applies the braking of individual wheels or reduces the engine power to restore the resistance of the car.
System of Electronic Control System (ESC):
Does not leave a single chance
Support in critical road situations
Loss of control when passing turn
The driver exceeded the speed, because of what he had to dramatically slow down in a steep turn.
In a normal situation, the car under the influence of the inertia would have to rolling on the roadside.
ESC system slows down rear wheelmoving along the inner radius of rotation by reducing the movement radius and allowing the car to fit safely in the turn.
Suddenly appeared obstacle
In case of a sudden occurrence, emergency braking may not be enough. To prevent collision, the driver needs to slow down and perform the maneuver of evasion at the same time.
Since the wheels of the car without ESC are blocked, the car ceases to react to the turns of the steering wheel and evaporate from the collision with an obstacle becomes impossible and the car breaks into the skid.
ESC system slows down front wheelmoving along the external radius of rotation and the car confidently circles the obstacle.
Safety Anniversary
Bosch celebrates the next anniversary. In 2015, it marks 20 years since the development and implementation of the ESP® electronic stabilization program.
The company's success story began in 1978, when she first created and launched ABS to serial production - anti-lock system with electronically controlwhich has become the basis for all the following systems active security.
In 1986, the ASR / TCS anti-test system followed it,
and in 1995 - ESP® / ESC electronic stabilization program.
Since 2009, Bosch, together with AvtoVAZ, implements in our country the program promoting the active safety of the car among Russian motorists.
Today, Lada Granta and Lada Kalina models are produced, which are equipped with an electronic stability control system (ESC).
For Lada Vesta ESC system will enter
to all basic configurations.
How ESC works
ESC system is active constantly. Sensor signals are processed by a microcomputer, which checks with a frequency 25 times per second, whether the driver's control force corresponds to the actual direction of movement. If the car moves in another direction, the system recognizes the critical situation and immediately reacts to it - regardless of the driver.
To return the car to the specified trajectory, the brake system is used here. Thanks to the selective engineering of individual wheels, the system creates the desired opposing force, and the machine behaves like that the driver wanted.
ESC system not only initiates intervention brake systemBut it can also force the engine to speed up the drive wheels. Thus, within the laws of physics, the car is reliably held on a given trajectory.
Data exchange S.
engine control unit
By bus exchange bus, the ESC control unit communicates with the engine control unit. In certain situations, it can reduce the engine torque when the driver presses too much on the gas pedal. You can also compensate for the excess slip of the leading wheels caused by the braking torque of the engine.
Power rotation angle sensor
Determines the position of the steering wheel. Based on the angle of rotation of the steering wheel, the velocity of the car and the brake pressure or position of the gas pedal, the trajectory of movement is calculated by the driver.
Wheel Corner Speed \u200b\u200bSensor
The control unit uses the information of the angular velocity of the wheels. The sensor is non-contact and measures the speed of rotation of the wheels through the magnetic field. It can determine the direction of rotation and the stationary condition of the wheel.
ESP® recognizes the critical situation and immediately reacts to it - regardless of the driver
Hydraulic unit with control unit
The Lada Vesta car is equipped with all the most necessary systems that contribute to the comfortable control of the car. All the listed systems are absolutely present in all confinement of the car, which makes it a very attractive figure in the car market.ABS or anti-lock system- In case of emergency, and sometimes regular braking, prevents the car's wheel lock, thanks to this system, the braking path of the car decreases, also during braking the ability to control the car due to the fact that the wheels are not blocked. When you work this system, you will probably hear the characteristic "crackle" and the lightweight brake pedal.
EBD or brake force distribution - correctly distributes the brake forces of the front and rear axis car, the system is activated with incorrect operation of ABS, is indicated by dashboard In the form of a red alarm - "brake failure".
BA or auxiliary braking - This function reads how quickly you have pressed on the brake pedal, from the data obtained the system recognizes whether the usual braking or emergency. In case of emergency braking, the system will increase the pressure in the brake system drive to a certain level and it will be kept until the brake pedal is pressed.
HHC or preventing car rolling while touching on the rise - when stopping the car on a slope, the angle of which is equal to four percent or more, the HHC system is activated to help in the future start of the car movement so that the HHC worked correctly, press the brake pedal with sufficient effort so that the car remains on the spot, after switching on the transfer, The release of the brake pedal and the press of the accelerator pedal, the system will hold the car in place until it starts the movement, but no more than two seconds. The system automatically turns off if the car stands on the parking brake or the driver's drive door is open.
ESC and TC - or resistance control and anti-pass system - Two of these car functions work in a pair and are activated automatically when the car engine is turned on. The ESC is responsible for the reliable stability of the car on the road, the system reads the speed of rotation of all the wheels and if one or more of them begin to rotate faster, the system slows down their rotation, in more serious situations, the system reces the engine speed, due to which the car handling returns. TC performs the same functions as ESC only when driving a car, which reduces excessive challenges of the car's wheels.

Photo "B"For those who do not know what kind of beasts are: ABS and ESP.
The ABS system is an anti-lock system capable of counteracting wheel scrolling during braking maneuver - it is necessary to ensure greater safety of movement.
The ESP system is a solution to ensure a course stability, designed to prevent machine driving (the necessary wheels are slowed down, it is controlled by the electronic unit). By the way, the ESP itself without ABS is absolutely useless, because it is, let's say, the imagination to it.
How does Vesta behave on ice using ABS and ESP?
We decided to experience Lada Vesta in winter Time - I wonder how the work of the above systems will behave. For testing, we selected an ice polygon with a length of 700m. It was important for us to find out in what cases the system will show well, and in what - well. For forest sustainability, we equipped with Nokian tires.
Usually, such tests begin with the fact that they turn off both systems. It is not surprising - because it is important for us to know how the car behaves on ice. To disable ABS + ESP, you will need to remove the voltage supply - namely, to remove the fuse responsible for their operation. If you do not pull it out, how much would you rather pull your finger into the ESP off button, the onboard electronics in any case will force it at a speed of over 50 km / h.
So, you start, the benefit of good studded tires help skin touching. We see a turn, try to fit into it - while we feel that the car begins to enter. The front wheels confidently hold the clutch with the track, but the ass is unstable - however, nothing is critical.
A motorist with experience without much difficulties will overcome a similar little skid, giving the accelerator pedal - good, the polygon allows it. The fact that the car rides even on the icing of the coverage is very confident, definitely pleases - while the quality of management does not suffer, Vesta clearly responds to the slightest rotation of the steering wheel, gently turns turns, does not julit while moving around the arc.
We stop and turn on anti-lock systems and coursework stability. We start and again in the path - while the car practically does not suffer from the loss of dynamics.
Once again, excellent wheels are out of us again. IN this case ESP + ABS respond to changing the conditions of motion is not instantaneous.
Most likely, the problems will start only with the total driving of the car. If you get into the real side demolition, the electronics are already unlikely to help you out. In such a situation, the chauffeur may not save the situation, because the management of TopLipodachi will already control the onboard electronics - as much as it will not receive an adequate reaction from the car.
Results:
Conducting the above described, one can boldly state that with disabled course stability systems and Vesta anti-blocking showed the time of passing the route for 8 seconds faster than when you turn on ABS and ESP. As it is not difficult to assume, such a result is associated with the fact that the operating systems included the actors of the driver in some way, spending precious time to evaluate responses different sensors. However, with an ordinary trip to the ice road of the system, on the contrary, they will only help when driving, preventing the course loss and driving.
How to ride - with ASB + ESP or without them, solve only you. Affect this decision only style ride and your driver's experience.
Cvet Test Lada Vesta with ESP and without
Winter road promises a lot of hidden dangers. Often, the right side of the roadside looks like a snow-covered smooth surface. However, a very large number of car enthusiasts, who, for one reason or another, should move onto it, with annoyance (and alas, with a delay) fall into the most real cuvette, covered with the appearance of the horizontal layer of snow.
Our new check Lada Vesta is designed to find out what pluses provide the ESP system, just intended to manage the distribution of the car's efforts in difficult situations. For greater clarity, we decided to move to the cuvette and try to get out of it first without a course stabilization system, and then with its use.
Immediately let's say, the car had to work hard. It is almost in a chattering state with two wheels balancing at the edges of the cuvette - in this case, as a rule, it is almost impossible without help from the side. But you dare to assure you, the factory electronics did not let us down. Side "brains" accurately dosed gasoline injection, allowing not just allowing the car to get up smoothly, but also to boil on the opposite side of the cuvette, returned to the roadway.
Recall, all the above maneuvers we performed with the ESP system involved.
Next we disable ESP. In this case, no attempts and tricks move the car from an uncomfortable position were not crowned with success. The wheels of the front axle only bought in the snow and the ice is stronger and stronger. You can go from the cuvette with such a situation with a lot of luck or with an extreme help.
Results:
Test results revealed unambiguous benefits provided by the ESP system on Lada Vesta. This also applies to the smooth road surface, and roads with bad crossings. In general, the presence of an electronic course stability system will be a great help for both beginners and experienced drivers - after all when you want to help whether it is worth refusing?
We test Lada Vesta on the rise in the slide with the on-and-off e-stabilization system
AvtoVAZ developed Lada Vesta to operate in an urban feature. But sometimes it happens that the machines sometimes have to leave the city, and it is no secret that the road covering outside the metropolis may contain potholes, holes and other irregularities.
New testing for Lada Vesta took place on a special highway, which is not better helped us to find out how it is still better to overcome rise to the slide - using eSP systems Or without such.
The last sedan, released AvtoVAZ really deserves special attention. Lada Vesta serial cars actively joined the total flow of participants road. Every day there are more information from people who are directly related to the operation of this car.
Manufacturers provided Vesta many innovations previously not installed on domestic Lady. Now, electronic security systems are on lada cars Vesta Even B. basic configuration. How effective are they and useful?
Reveal some questions will help tests conducted in various situations.
Like ESP and ABS affect the stability of Lada Vesta on the icing coverage
Lada Vesta continues to undergo trials in winter time of the year. This time, a 700 m sports ice trail is chosen as a polygon. The purpose of the inspection is the testing of electronic systems for stabilizing the movement of Lada Vesta in various situations. As it should be, the car is dressed in winter studded nokian tires.
The first test was conducted with disabled ESP and ABS systems. To do this, you must completely delay them, i.e. to remove the fuse. Otherwise, even with a keystable system shutdown key, the computer will turn it on independently, when a speed is 50 km away.
The sedan is rolling in the start. Make yourself known spikes on wheels. When entering the turn, the machine demolides, but not much. Leading wheels clearly control the road, and the ass starts to demolish. An experienced driver can easily cope with such a situation by adding gas for which there are no restrictions. Even on Ice Vesta behaves predictable. Once again, there should be excellent handling. The machine adequately responds to each steering movement, smoothly turns into turns and behaves well when the arc moves.
In the second case, the entire electronics is connected. From the start, it can be seen that the car does not lose its dynamic. Again, I would like to note the presence of good studded rubber. ESP and ABS systems do not immediately respond to changing the situation. Troubles can begin only after the complete demolition of the car. In this case, the carrying sideways of Vesta is already beyond the electronics. At the same time, the driver is harder to cope with the situation, because the gas is under the control of the computer and strong pressing does not bring the result.
Output
Comparing the results, it can be noted that when driving help systems are turned off, the car passed the track faster for as many as 8 seconds. A slower passage with ESP and ABS works is associated with estimated electronics actions. Nevertheless, it significantly unloads the driver's voltage when the Vesta Lada is moving on ice. The choice of driving with the included electronics or without depends solely on the experience and style of driver driving.
In addition to ice and snow, winter can present other conditions in which the electronics installed on the car will be able to pull out of a practically hopeless situation.
Lada Vesta in Kuvette: Stabilization System
On the winter Road A situation may occur when the car is forced to cuddle to the side of the route. At the same time, frequent cases of climbing in a cuvette. The next test drive of Lada Vesta showed the advantages of the course stabilization and control systems under difficult conditions. This showed a comparison without ESP and with ESP.
Sedana was given a hard task. The car was practically hung between the edges of the ditches on two wheels. Usually, this situation requires mandatory assistance from the outside. But the electronics coped perfectly with the task. Equally distributing the supply of fuel, it easily allowed not only to align weta. Sedan, like a crossover with ease climbed on the opposite of the ditch of ditch and also just returned to the main road.
In the second case, with a similar situation, the ESP was disabled. No effort and Peregazov failed to move the car from the scene. Leading wheels only smelled of ice and snow. In this position, without outside interference, leave the cuvette is almost impossible.
Output
The electronic stabilization system of the movement and control of Lada Vesta's traction proves its advantages, both on a smooth coating and off-road. It is useful not only to beginners, but also drivers with experience who believe that they themselves are able to solve all questions. After all, if there is an ESP, they simply will not arise.
Traction Control and Lada Vesta on the lifting
Sedan Lada Vesta is intended for urban conditions. But in any case, he will have to sometimes leave the limits of megacities. On the way there may be pits, bumps and steep hills.
Regular test Drive Lada Vesta passed on the crossway, where it was compared how it is better to overcome the rise - with electronics or without.
Four test options were chosen. In the first two cases, all the help systems of the driver were included. With a smooth start, the car did not reach half of the elevation. The engine did not have time to gain momentum and refused to further pull the car. An attempt with acceleration gave the best results. The car rose to the meter further and stopped.
Disconnection of tracking control slightly changed the situation. Smooth start, as in the first case did not show special results. Having achieved a certain level, Vesta wasted to rake soil. Overclocking has long increased distance traveled.
Output
Such situations are not uncommon. As in most cases, the exit from the situation depends on the driver's experience, because the electronics is not yet able to solve all the problems.
Speed \u200b\u200brequires a reliable brake system. After all, blocked wheels are often caused by strong drift, which can lead to trouble. How can electronics help with a sharp press on the brake pedal?
How effective is ABS Lada Vesta System
Another test drive gives information, as it may affect the disconnection of ABS Lada Vesta on the brake characteristics of the car.
The car was tested on loose snow and pure ice. Included electronic systems allow you to drive a car with ease. Snow and ice cease to be obstacles even for novice motorists.
Check showed the following results. ABS, together with ESP, effectively coped with its task. The car made smooth braking even when the steering is scored. There was no speech about any risk. Most otherwise they went after the disconnected system of distribution of brake efforts. This time the braking path became shorter, but the procedure demanded a significant drive voltage. Even with great experience, the car went to the skid.
conclusions
Despite the shorter braking path, disconnecting ABS to Lada Vesta is not recommended. New systems do not work as earlier options when they did not control rear axle. The car could have remained in a stable position. In the present version, when ABS is turned off, the cylinder evenly distributes the brake force between all four wheels. With a strengthened press on the brake pedal, all the wheels are blocked and the car becomes completely uncontrollable. Bar was secured.
Lada Vesta has quite decent dynamic characteristics. But, they describe the position of affairs on a good, dry road surface. What will happen to a set of speed if the car is on a snowy or icing road?
Electronics Lada Vesta passes in Lapland
Another test drive Lada Vesta in winter was held in Finland. For this, the test site of Nokian Tyres was highlighted, in which the Russian sedan tests tires.
The subject of testing was again the system of course stability, around which constant disputes go. Experienced drivers believe that ESP and ABS are needed only by beginners and are an expensive toy.
The road surface was a lot. Systems had to show their effectiveness with a sharp and smooth start. In the first case, the car required more time on acceleration. With a sharp pressure of gas, the car quickly begins to gain momentum, the wheels are slipped. Only after a moment, the electronics and acceleration becomes controlled. Smooth pressing on the accelerator pedal allows the ESP system in a timely manner to distribute the clutch of the wheels with an expensive and evenly disperse the machine.
A similar situation with the "Treatment Control" turned off that with a sharp start, there is a strong slip, leading to loss of time. Smooth start showed best results. An experienced driver feels well the behavior of the car and distributes the press effort.
On loose snow, the results with the ESP enabled with a smooth and sharp start turned out to be almost the same. The disconnection of the electronics made it possible to obtain the most efficient acceleration, and again, smoothly pressing the pedal has reduced the speed set.
Output
The results obtained were again reduced to the fact that the main advantage of the management is the skill of the driver. However, even experimental motoristsOver time, it will become clear that ESP and ABS can make it easier for the driving of Lada Vesta.
The active safety of the car includes electronics that allows you to prevent an accident. Lada Vesta is equipped with many such assistants who contribute to the preservation of the car manageability when traveling. Among other things, the driver should know how it works anti-slip system Lada Vesta.
For the movement of the machine, the grip with the road cannon is important. But his reliability drops greatly if the road is wet or slippery, which is why the probability of slipping increases. It becomes the cause of such trouble as:
- loss of speakers during acceleration;
- degraded handling;
- high probability of drift;
- increased tire wear.
The Stability Course System on Lada Vesta works in binding with anti-bounce (TCS), which allows the driver to touch from space on a slippery surface with a minimal probability of slipping.
In fact, it looks like this: if the wheel when acceleration begins to rotate too fast, the sinking system works and accepts corrective measures: slow motion or reduction of the transmitted torque. The car at the same time remains stable.
On a note!
In Lada Vest, Antibux works in all configurations.
How to disable the anti-slip system
TCS is turned on immediately after starting the engine. Disconnection is possible with ESC. To do this, press the key on the central console. Separate shutdown is not provided.
Reliability TCS on Lada Vesta
Each car stabilization system has undergone tests with different condition road coat (wet asphalt, slush, holly, etc.). The TCS anti-test system has shown itself from the best side: "interferes" only if necessary and perfectly triggered with another electronics.
The owners are also mostly satisfied, although some time it took to adapt to the entire functionality of Vesta.
On a note!
It is better to think about several times before turning off TCS. Electronic security systems, including Antibux Lada Vesta, increase your chances of a safe outcome of a dangerous situation on the road. Yes, and under normal driving conditions, you can feel more confident, knowing that there is such a substitution.
