Abstract
An acceleration slip control system for a motor vehicle operates so that a request for the upshift of the transmission of the motor vehicle is not output to upshift device in accordance with a road surface condition detected by road-surface condition detection device, on the basis of the detection results of engine revolution-speed detection device and driving-wheel slip detection device, whereby the inferior acceleration of the motor vehicle attributed to the upshift is prevented in order to perform the optimum gear-shift control conforming to the road surface condition.
