PURPOSE:To enable a wheel slip to be correctly detected before its generation, by deciding a wheel in a slipping condition when an arithmetic value of driving wheel acceleration, where no slip is generated in the driving wheel, is larger than a detection value of the driving wheel acceleration by a predetermined value or more. CONSTITUTION:When a vehicle is in operation, an electronic control circuit 20 first calculates rotary acceleration alphaB' which can be generated in a condition that no slip is caused in a driving wheel of the vehicle. This acceleration alphaB' of the driving wheel is obtained by the conversion from a vehicle acceleration alphaB calculated by using driving force and running resistance obtained from an output of a throttle sensor 10, rotary angle sensor 18, etc. and the total weight of the vehicle and gravitational acceleration. And the control circuit 20, deciding the wheel in a slipping condition when this driving wheel acceleration alphaB' is larger than an actual driving wheel acceleration alpha detected byd a driving wheel acceleration sensor 26 by a predetermined value or more, prevents in accordance with this decision result the generation of a slip before its occurrence by controlling driving force of the wheel. |
