This paper presents two fuzzy logic traction controllers and investigates their effect on longitudinal platoon systems. A fuzzy logic approach is appealing for traction control because of the nonlinearity and time-varying uncertainty involved in traction control systems. One controller estimates peak slip and regulates slip at that value. The controller is attractive because of its ability to maximize acceleration regardless of road condition. We find through simulations the controller's performance degrades in the presence of time-varying uncertainties. One of the controller inputs, dmy/dt is difficult to estimate from vehicle acceleration when time-varying uncertainties exist. The other fuzzy logic controller regulates slip at any desired value. Through simulations we find the controller robust against changing road conditions and uncertainties. The target slip is predetermined, and not necessarily the peak slip for all road conditions. However, if the target slip is set low, stable acceleration and deceleration is guaranteed regardless of road condition. Using simulations we evaluate the effect of traction control on longitudinal platoon systems. The simulations include acceleration and deceleration maneuvers on an icy road. The results indicate traction control substantially improves longitudinal platoon performance with icy road conditions. In addition, traction control provides additional safety if emergency stopping or acceleration is required.
