Abstract: Recently, Traction Control System (TCS) which maintains stability and steerability of vehicles on low-_μ surface roads, by controlling the slip ratio between tyre and road surface, is attracting attention. In this paper, the control stability analyses of TCS with computer simulations and vehicle tests are described. In the first place, the control stability in the balancing state is examined with a simplified model. Secondly, with a full-vehicle model, the control stability is examined. These results show that the control stability can be improved by adjusting the P-1 control gains, and furthermore, brake application is effective for preventing excessive wheel spin.

Keywords: control gain; steerability; traction control systems; vehicle stability; slip ratio; tyres; road surfaces; simulation; vehicle modelling; wheel spin; vehicle design.
