Abstract
This invention has traction control means having slip detecting means for detecting slipping of driving wheels, in accordance with an output signal from the driving wheel velocity detecting means and an output signal from the vehicle body velocity detecting means, and output rate calculating means for generating first instruction A for controlling engine output, in order to immediately decrease a slip rate, based on a slip start signal from the slip detecting means and for, when the slip rate is decreased to a predetermined value, generating second instruction B for controlling the engine to provide an output according to friction coefficient .mu. between a road surface and wheels, and engine output control means for controlling engine output on the basis of the first and second instructions and vehicle operating conditions.
