Most of us heard the name of ESP for the first time after the tumble failure of Mercedes A class cars. In slalom tests carried out by automobile magazines, after the vehicle rolled over in sudden maneuvers, Mercedes fitted this system to all A class cars and solved the problem.
The principle of ESP is actually very simple. All 4 wheels are capable of supplying gas and braking independently. Of course, we do not do this with 4 gas and 4 brake pedals. As soon as one or more wheels tend to slip due to the deterioration of the physical balance of the vehicle in sudden maneuvers, the ESP system is activated and applies gas or brakes to the relevant wheel, depending on the direction and direction of the car. So how does this system detect the vehicle slipping? As you will see in the following figure, there are various systems and sensors connected to the ESP system. Of these, I will use to explain the incident to you, "Wheel Speed Sensor", "Lateral Speed Sensor", "Steering Angle Sensor" and "Brake Pressure Sensor". Now let's imagine that the back of our car is slipping, let's see how ESP will understand this.
First of all, when the back of the car is knocked up, the Lateral Speed Sensor will perceive very simply that the car is showing an imbalance in the lateral direction, that is. In addition, Wheel Speed Sensors will find that when the rear wheels begin to slip, their rotational speed is less than that of the front wheels, likewise, the Brake Pressure Sensor will also be able to recognize that the rear grip has disappeared in the same way by noticing that the rear wheels have less braking pressure applied to the front wheels. Finally, if we need to explain how the Steering Angle Sensor works, it is sufficient to think that the car slipped from the head. In a fast bend, you turn the steering wheel, but the front of the car is not turning because you go too fast. (This event can be easily understood in front-wheel drive cars when the gas is pressed in the bend).
In this case, the ESP system detects that the car slips out of the head, that is, the front wheels lose grip, since the Lateral Speed Sensor cannot feel a rotational movement even though you turn the steering wheel. After all this information, we can explain how the ESP system works in the example in the figure.

6) Automatic Gas Valve / Injection Pump
7) Brake Pressure Sensor Tractor brakes
Those who know can easily understand this issue.
Tractors have two brake pedals that control the rear wheels. When you reach from one end to the other while driving the field, you can return the tractor where it is by pressing only one of these pedals.
For example, if you just press the right brake pedal, the tractor's right rear wheel brakes and the tractor starts to turn right around itself. Here, we can say that ESP was inspired by these tractor brakes. So it's just an advanced and electronic tractor brake. There is only one plus aspect, it can save your life, or how many billions of damages you may have in your car ...
After all, one way or another, ESP is extremely useful, making it almost impossible for the car to slide. |
