Vehicle electronic stability control system is a newly developed electronic device in recent years, which is the inheritance and further expansion of anti-lock braking and traction control functions. Bosch Company of Germany began mass production of anti-lock braking system in the mid-198s, which greatly improved the braking stability of vehicles.
However, it was later found that the anti-lock braking system could not solve the wheel slip problem when vehicles started and accelerated on low adhesion roads. Although the patent to solve the problem of driving wheel slip has appeared since 197s, traction control technology was not put into practical use until VOLVO Company developed the first set of electronic traction control system products. In 1986, Bosch integrated the anti-lock braking system and traction control system and applied them to Mercedes S-class cars, which marked the coming of the era of ABS/TCS integration.
Extended information:
Under certain road conditions and vehicle load conditions, the maximum adhesion that a wheel can provide is a constant value, that is, in the limit case, the longitudinal force (along the rolling direction of the wheel) and the lateral force (perpendicular to the rolling direction of the wheel) are changing. The electronic stability program can control the longitudinal braking force of each wheel separately, thus exerting influence on the lateral force, thus improving the handling performance of the vehicle.
when the longitudinal force reaches the extreme value (for example, the wheel is locked), the lateral force is zero, and the lateral movement of the vehicle will be out of control, that is, sideslip will occur, and it may be impossible to change lanes or turn according to the driver's wishes. The electronic stability program can detect and prevent the vehicle from skidding. When the electronic stability program detects that the vehicle is about to get out of control, it will apply braking force to specific wheels to help the vehicle move in the direction expected by the driver. ?
When turning, a feasible control strategy is as follows: when the vehicle tends to understeer, the system can apply braking force to the rear wheel inside the turn, and the lateral force provided by this wheel decreases due to the increase of longitudinal force, which will then produce a torque to help the car body turn;
when there is a tendency to oversteer, the system can apply braking force to the front wheel on the outside of the turn. As the longitudinal force of this wheel increases, the lateral force it can provide decreases, which in turn produces a torque against steering on the car body. Thereby ensuring the stability of driving. Some electronic stability program systems will also reduce the power of the engine when the vehicle is out of control.
