Abstract
A system for controlling motor vehicle driving force comprises means for detecting the rotational speed of each of the driving wheels and a driven wheel, means for controlling brake means for the driving wheels according to the output of the detecting means, first comparing means for comparing the rotational speed of the driving wheels with the rotational speed of the driven wheel, calculating means for determining a slipping ratio corresponding to the ratio of the rotational speed of the driving wheels to the rotational speed of the driven wheel, second comparing means for comparing the output of the calculating means with a predetermined threshold slipping ratio, third comparing means for comparing the rotational speed of the driven wheel with a predetermined reference speed, and switching means for connecting the output of the first comparing means to the control means when the rotational speed of the driven wheel is lower than the predetermined reference speed and connecting the output of the second comparing means to the control means when the rotational speed of the driven wheel is higher than the predetermined speed. The switching means is changed by the output of the third comparing means. A method of controlling motor vehicle driving force also is disclosed.
