Abstract
An apparatus for applying brake to right and left drive wheels to reduce slip of the wheels upon detection of the slipping conditions of the wheels under acceleration. The apparatus has a target determining device for determining the manners or modes of applying the brakes to the two drive wheels in different fashions. For one of the two drive wheels which has a comparatively large slipping tendency, a nominal control mode corresponding to the detected slipping condition is selected. The control mode for the wheel having a low slipping tendency, a mode different from a nominal mode corresponding to the detected slipping condition is used, under predetermined conditions, so that the actually used control mode is closer to the nominal mode used for the wheel having the large slipping tendency, in order to assure an optimum compromise between the drivability or acceleration of the vehicle and the avoidance of the wheel slipping condition. The degree in which the actually used control mode of the wheel having the low slipping tendency is close to the nominal control mode of the other wheel differs depending upon the difference between the nominal modes of the two wheels corresponding to the detected slipping conditions.
