If the rear of the car can quickly follow the front of the car to complete the curve at the same angle without any swing, we say that the car has good tracking performance. This is mainly related to factors such as rear suspension and tire performance. In daily driving, vehicles with good tracking can pass through sharp corners more safely and quickly to ensure driving safety.
Tracking control system is a unified method to control vehicle slip. Generally can be divided into two kinds. One is to use the braking system when the driving wheel slips, that is, to increase the braking oil pressure of the slipping wheel and control the wheel slip by implementing appropriate braking restrictions. The other is to use the braking system to increase the output force of the pilot engine, so as to delay the ignition of the pilot engine and reduce the fuel injection, or to adjust the opening of the throttle valve, so as to reduce the driving force of the driving wheel and prevent the driving wheel from slipping.
These two control formulas have their own advantages and disadvantages. The control speed of braking control formula is faster, so the reaction speed of braking and coasting is faster, while the control formula of guiding engine output force is slower, but it should be smoother and more comfortable. The advanced tracking control system has basically integrated abs, tcs or asr, and the commonly used tracking control system in the market is ABS+ brake control system. Or abs+ traction control system, or abs+ brake control system and traction control system.
