A traction control algorithm is presented in this paper. The control effect as well as adaptability were studied by the simulation. Mathematical models of acceleration were established, PI control was applied to design engine throttle controller, and the logic threshold control was used to design brake controller of driven wheel. At the same time, a road identification system was designed to identify the changes of roads. Investigation and research of traction control algorithm were made on the roads with various adhesions of road surfaces. The simulation results indicated that the TCS control algorithm could prevent driven wheel from being excess spin, improve acceleration performance, and identify the changes of road accurately.
