Abstract

A cooperative traction control system that integrates throttle control and torque distribution. The system also uses dual slip controllers and methods that involve controlling the distribution of torque between wheels in the front and rear axles of a vehicle and a relatively small or no adjustment of the engine throttle (or, more generally, engine torque output) to reduce wheel slip. The control is cooperative in the sense that two controllers—a front axle torque controller and a rear axle torque controller—work together (or are controlled together) to reduce wheel slip and thereby achieve improved straight-line movement of a vehicle from a standstill.
