Abstract
This paper introduces a new traction control method that assures vehicle operational stability on a low friction road. On a low friction road, the vehicle becomes unstable as the drive wheels spin under excess engine torque. Instead of using friction coefficient versus slip-ratio curve and exact vehicle speed, this paper uses a friction coefficient detector. Accordingly, the concept of Sign of Torque Change relative to Friction Coefficient (STCFC) is introduced and applied to a rule-based traction controller. In order to perform simulations, a formula that represents the traction force versus longitudinal slip was proposed. Simulation results verify this approach.
