    摘要： 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.

    摘要： A system for controlling an electro-magnetic clutch of an internal combustion engine mounted on a vehicle, which is capable of eliminating residual magnetism during operation of a shift lever of a transmission. The electro-magnetic clutch has a drive member secured to a crankshaft of the internal combustion engine, a magnetizing coil provided in the drive member and a driven member adjacent said drive member. A neutral switch is provided for detecting when the shift lever is in a neutral position and a shift lever switch is provided for producing a signal during operation of the shift lever for the transmission. Both signals of the neutral switch and the shift lever switch are fed to a control circuit. The control circuit is so arranged that the current flowing through the magnetizing coil is inverted in dependency on the output signals of the neutral switch and shift lever switch, so that the residual magnetism in the clutch may be eliminated.
