Why do we need to set up a switch for the car's body stability system?

ESP is a safety feature of the car. Basically all cars nowadays are equipped with it. It is a very important active safety system in the car. The car body stability system is related to the safety of the vehicle and can also save lives in emergency situations. Why does the body stability system, as a vehicle electronic safety feature, need a switch?

The vehicle stability control system is basically an active safety system that prevents the vehicle from skidding, causing loss of control, rollover, oversteering or understeering in an emergency. In simple terms, it maintains the stability of the vehicle's driving condition and the controllability of its direction. According to its own structure, ESP uses various sensors to achieve wheel speed balance and rotation speed consistency, realize wheel braking, and create a rotation speed difference between its wheels.

The purpose of setting the switch is to enable the vehicle to meet driving needs in some special environments or working conditions. From the function, we can see that the existence of ESP can control the rotation speed of the vehicle wheels to maintain the balance of the vehicle body and avoid tilting and overturning. The existence of the switch can help the vehicle get out of trouble in special environments. For example, when the vehicle is driving on mud or snow, this type of road is very slippery and there is basically no adhesion for the vehicle's wheels.

When the vehicle is running, it may slip and other situations. According to the work of ESP, the vehicle control unit will instruct ESP to start and brake some wheels. It is very difficult for the vehicle to get out of trouble, just like when we are on a slippery road, if we want to move quickly, we must intervene with external force. When ESP is turned off, the speed of the wheels of the vehicle is different, and the output torque and moment are also different, so the generated wheel speed is also different. Let the wheels spin idly and rush up by inertia to get out of trouble. So it can be seen from this that the existence of ESP is very important.
