  • Patent number: 5159990
    Abstract: A slip control apparatus for use in a motor vehicle having an engine for generating a motive power to drive the motor vehicle. The apparatus comprises a first detector for detecting a speed of a driven wheel of the motor vehicle which is driven by the motive power generated from the engine, a second detector for detecting a running speed of the motor vehicle and a third detector for detecting an acceleration of the driven wheel. Also included in the apparatus are a decision unit for determining the occurrence of slipping of the driven wheel on the basis of the detection results of the first and second detectors, a driving force adjusting device for adjusting a driving force of the motor vehicle, and a control unit for controlling the slip of the driven wheel on the basis of information from the first to third detectors.
