Abstract
In a system for preventing an excessive slipping of a drive wheel of a vehicle, including a drive wheel torque decrement calculating means for calculating a drive wheel torque decrement in accordance with the slipping state of the drive wheel on the basis of a drive wheel velocity and a vehicle velocity, there is further includes a switchover means which produces a torque decrement switchover signal in accordance with a further large slipping of the drive wheel appearing during a given torque reduction control, and a torque decrement changeover means which delivers, to the drive wheel torque decrement calculating means,a correcting signal indicative of a command to reduce the degree of relation of the torque decrement to the slipping state of the drive wheel in accordance with an output of the torque decrement changeover signal from the switchover means, whereby it is possible to avoid a control hunting which may be caused by a larger slipping state of the drive wheel due to a disturbance factor.
