ABSTRACT:
A control system for a motor vehicle provided with a clutch and a continuously variable transmission. The transmission has a line pressure control valve having ports and a spool for controlling the line pressure of oil supplied to a cylinder of a pulley device to change the transmission ratio. The transmitting torque in an engine power transmission system is detected and a clutch torque dependent on the transmitting torque is obtained. The line pressure is set to a minimum value sufficient for holding a belt of the pulley device for transmitting the clutch torque.
