ABSTRACT:
A system and method for controlling vehicle traction uses estimates of external conditions from vehicle and engine measurements in a feedforward manner to control vehicle traction on slippery or changing surfaces and hills to compensate for external disturbances in an optimal manner. The present invention provides a dual feedforward/feedback system for a method of controlling vehicle traction. The method includes the step of generating a first feedforward value related to the slope of a hill and a second feedforward value related to the coefficient of friction of the load surface. The first and second feedforward values are then summed to generate a feedforward control value for controlling the level of vehicle traction. The system for controlling vehicle traction includes a first feedforward value related to the slope of a hill and a second feedforward value related to the coefficient of friction of the road surface. The first and second feedforward values are summed to generate a feedforward control value for controlling the level of vehicle traction.
