He will talk about what the ABS, ESP and TSC systems are like, what is the difference between them and what is their principle of operation. He will tell about what ABS, ESP and TSC systems are like, what is the difference between them and what is their principle work.
It is simply impossible to imagine a modern foreign car without an auxiliary braking system or an air conditioner, often it is no longer a luxury, but a necessary component of a complete set.
Accidental obstacle or accidental pressing of the brake pedal, skidding of the car can lead to loss of control and death. Every driver has had such a case.
What is ABS, TSC and ESP
The first systems that allowed the driver to align the car and keep the course of movement began to be established twenty years ago. ABS or, more precisely, Anti-lock Braking System, are now not installed on cars, since they were replaced by newer ones, but nevertheless, they were the beginning of exchange rate stability systems.
There are three main components in ABS:
- Sensors for picking up the wheel speed;
- A device for changing the pressure in the brakes, for each wheel separately;
- Process control unit.
The principle of operation is not very complicated, it all starts from the moment when the sensor detects the wheel lock, transmits a signal to the control unit. The control unit, after processing the data, transmits a signal to the module to reduce the pressure in the brake system of the wheel, which has been blocked. When the wheel begins to rotate normally, the pressure returns to its original position, the cycle continues until the threat of blockage disappears. The driver will feel a slight beat on the brake pedal.
Not unimportant systemic is considered to be TSC, better known as ASC or ASR. Allows you to start from a place without slipping the driving wheels, it is very convenient to use when starting on snow or a track covered with ice. The system is based on the same sensors, only the control module has been improved, the wheel recognition function has been added to it. Thus, if during the start, the drive wheels rotate faster than the driven ones, then the control system perceives this as wheel slip. The control unit will reduce the engine speed, no matter how hard you press the gas pedal, and the car moves smoothly. The newer and modernized ESP system (Electronic Stability Program "Stability Program"), can not only control the braking system, but also the engine ... On SUVs, it was endowed with the ability to lock a differential. In BMW cars it is x-Drive, and in Mercedes it is 4-Matic. In addition to the standard sensors that were used in ABS, we also added side sensors, steering, skid and other sensors that make it clear to the system what is happening with the car while driving. Thus, when the system is turned off, all data is transmitted to the monitor of the on-board computer, and it makes it possible for the driver to understand the situation on the road, the temperature outside the car and what the state of the road is. This greatly facilitates driving and gives confidence in the car, even without the system, you can make a decision in a particular situation to maneuver.
How ABS and ESP work
Consider a situation when a car enters a bend and starts to skid to the side, turning the steering wheel in the direction of a skid, the driver will go out of the bend, and ABS will slow down as expected. But still, the last decision will remain with the driver, turn down the gas or slow down. With the ESP system, the situation is completely different. First, it will reduce the fuel supply in order to reduce the rpm and power of the engine, because of this, the speed will also decrease. Further, the system itself will determine which of the wheels should slow down more and which should not be touched at all, using the steering sensors, it will tell you which way to turn the steering wheel in order to return to the previous driving trajectory.
Experienced drivers say that it is not worth playing with these systems, that is, often and successively pressing the brake pedal, then the system will perceive it as an emergency and will start to work unnecessarily.
