  • Acceleration slip control system for motor vehicle
    Patent number: 5741051
    Abstract: In an acceleration slip control system for a motor vehicle, a load to act on a differential mounted in the motor vehicle is lightened to prevent the differential from seizing up. In a case where the rotational speed difference of driving wheels detected by a speed difference detector during acceleration slip control is a predetermined value or greater, the method by which the acceleration slip control is performed using a braking control device and an engine output control device is altered by a specified control unit. Braking control and/or engine output control are performed dependent upon the deviation of the speed difference of the wheels from the predetermined value, which can in turn be adjusted dependent upon the load state of the differential.
