ECU (System of Electronic Control of Stability). See ESC

ESC (Electronic Stability Control) - electronic control of stability.

ESP ® (Electronic Stability Program) - Bosch electronic stabilization program. 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 together by S. aBS systems and EBD. 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

Facilitates the start by maintaining 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

Brake effort distribution system is designed to prevent blocking rear wheels Due to 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 traffic 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 - electronic program stabilization ESP.® / ESC.

Since 2009, Bosch, together with AvtoVAZ, implements in our country the program promoting the active safety of the car among Russian motorists.

Today are models Lada Granta. and Lada Kalina. 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 sensor information corner speeds 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

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.

ESP system is a solution to ensure currency stability, designed to prevent car drifts (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 her.

How does Vesta behave on ice using ABS and ESP?

We decided to experience Lada Vesta. In winter, it is interesting 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 it does not pull out, then no matter how much you do not poke a finger in the off button ESP, on-board electronics in any way forced to include it at a speed exceeding 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 instantaneously.

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, this result is associated with the fact that the operating systems included the driver's actions in some way, spending the precious time to assess the responses of various 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 of Lada Vesta is designed to find out which 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 test for Lada Vesta was held on a special track, which is the best help us to find out how it is better to climbing the hill - with eSP systems Or without such.

Modern Western models complex electronic assistants The driver may include more than a dozen-two different systems. In-grade state employees, such a luxury is not yet allowed on the status, but for this part of Vesta is ready to give odds to competitors. In addition to the usual set of ABS and EBD, the VAZ novelty is already in basic configuration Equipped with a course stability system (ESC). For the winter, her behavior managed to learn enough to put it with the highest rating.

First, it gives an eye to batch on the first gear, allowing you to overcome the difficult area of \u200b\u200bthe yard or unscredited parking. In this case, the anti-test system in this case can interfere - and does it right. Similarly, it behaves and with an excessive launch start from the traffic light on slippery asphalt. It also my soul: there is no hysterical help of electronics in those situations when it is not required at all.

I note that over the past snowy winter, the stabilization system never worked unexpectedly for me. Speak it on good winter tires and right choice Speed. But B. safe places It was evaluated with it.

And what do you think, should ESC make a mandatory equipment for inexpensive models? Doesing it, in your opinion, is the real benefit or is it another way to contemb more money from the buyer?

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 be aware of how the anti-slip system of Lada Vesta works.

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 as if the wheel during acceleration begins to rotate too quickly, probuksovochnaya system works and takes corrective measures: snubs or decrease 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 was subjected to tests with different condition of the road surface (wet asphalt, slush, ice, 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.
