Why can't Kepstar catch the rear wheel brake?

During the braking process, the ABS control unit continuously obtains the wheel speed signal from the wheel speed sensor and processes it to judge whether the wheel is about to lock up. The characteristic of ABS braking is that when the wheel tends to the locking critical point, the pressure of the brake cylinder does not increase with the increase of the pressure of the brake main pump, but changes near the locking critical point. If it is judged that the wheel is not locked, the brake pressure regulating device will not work and the braking force will continue to increase; If it is judged that a wheel is about to lock up, ECU sends an instruction to the brake pressure regulating device to close the passage between the brake cylinder and the brake wheel cylinder, so that the brake wheel pressure will not increase; If it is judged that the wheel is locked and dragged, an instruction is sent to the brake pressure adjusting device to reduce the oil pressure of the brake wheel cylinder and the braking force.

Body electronic stability system ESP

Some friends have also heard of ESP body electronic stability system. What kind of system is this? In fact, the body electronic stability system is a patent of Bosch. Other companies have developed similar systems, such as BMW's DSC, Toyota's VSC and so on. Their functions are similar. Don't think that without this name, there is no such function.

When the car is driving fast or turning, the lateral force will make the car unstable and prone to accidents. ESP system can prevent problems before they happen. When an obstacle suddenly appears in front of the vehicle, the driver must turn left quickly. At this time, the steering sensor transmits this signal to the ESP control assembly, and the sideslip sensor and the lateral acceleration sensor signal that the vehicle is understeer, which means that the vehicle will directly rush to the obstacle. Then the ESP system will brake the rear wheel in an instant, generating the reaction force needed for steering, so that the car can drive according to the steering intention. If the car turns in the left lane after turning, it will be in danger of oversteering, and the torque to the right is very large, and the rear of the car will be thrown to the left. At this time, the ESP system will brake the left front wheel, which will reduce the torque and make the car turn smoothly.
