Abstract
A control system for a motor vehicle provided with a continuously variable transmission and a clutch for transmitting power of an engine to the transmission. The transmission has a transmission ratio control valve having ports and a spool for controlling the transmission ratio. A throttle position sensor is provided for detecting the load on an engine and for deciding a desired transmission ratio in accordance with the load. The clutch is automatically disengaged at low vehicle speed. When an accelerator pedal is depressed in order to re-accelerate the vehicle, the desired transmission ratio is increased to increase the speed of a drive pulley of the transmission so that the drive pulley speed equals the speed of the engine.
