PURPOSE:To permit the correct judgement by calculating the variation amount of the driving wheel speed before and after the fulfillment of conditions when the opening degree of a throttle valve or the variation amount of the opening degree becomes over a prescribed value, and judging the acceleration slip when the variation amount is over a prescribed value. CONSTITUTION:In the acceleration slip detection treatment in an electronic control circuit 30, the opening degree ALPHA is over a prescribed value K or not, and when the judgement is YES, it is judged that a car is in acceleration, and the time intervals before and after the newest time interval calculated at present among the time intervals corresponding to the driving wheel speed obtained from the output of a car speed sensor 31 are read. Each amount of variation of the both time intervals is calculated, and when the variation amount is over a prescribed value, it is judged that acceleration slip is generated, and then the engine output is suppressed and acceleration slip is prevented. |
