Abstract

This paper presents simulation results related to the terrain-adaptive Traction Control System (TCS) first proposed by Burg and Blazevic (1997). The TCS avoids wheel slip greater than the critical wheel slip Scr during acceleration and deceleration. Slip values in excess of Scr are detected without knowledge of Scr'S actual value (which depends on tire/ground combinations). The TCS adapts itself to every kind of terrain. Sensor instrumentation. crucial for system stability, is also discussed. An implementation of the proposed TCS within a virtual environment shows the vehicle's motion under changing traction conditions. Wheel slip and related traction forces are compared with classical and inactive TCSs.
