Development of TCS slip control logic based on engine throttle control

Slip control systems are used to prevent wheel slipping and to improve acce leration performance, stability and steerability on slippery roads through the engine torque and/or brake torque control. This paper mainly deals with the engine control algorithm via adjustment of the engine throttle angle. The slip control algorithm developed in this research includes a control ga in scheduling part and a road estimating part to enhance control performanc e. Various actual vehicle tests have been carried out on low friction roads in order to verify the developed slip control algorithm. The test results show that the controlled vehicle is superior to the non-controlled vehicle in acceleration performance and stability.
