Abstract
An acceleration slip control device for a vehicle, by which the slip between driving wheels and a road surface during a start and an acceleration of a vehicle is maintained at level ensuring a good acceleration and straight line running stability. The device controls the slippage of the driving wheel by adjusting a drive torque according to the amount of a deviation of the actual speed of rotation of the driving wheels from a target speed of the driving wheels. The drive torque is controlled in such a manner that the rate of change of the drive torque includes a component proportional to the rate of change of the slippage of the driving wheels and the proportional factor is selected in such a manner that the proportional factor is larger when the component acts to increase the drive torque and is smaller when the component acts to decrease the drive torque.
