Abstract:
A starting clutch control system arranged behind an output shaft of a continuous variable transmission in which revolution of an input shaft applied from an engine is transmitted in a continuously variable way, comprising means for monitoring vehicle running conditions, means for setting a desired torque to be transmitted through the starting clutch according to the vehicle running conditions monitored, means for monitoring an actual torque transmitted through the continuous variable transmission, and an engaging-pressure control valve for developing an engaging-pressure to be exerted on the starting clutch, the engaging-pressure being proportional to a deviation of an actual transmitted-torque signal corresponding to the actual transmitted-torque measured at the actual torque monitoring means from a desired transmitted-torque signal corresponding to the desired transmitted-torque derived from the desired transmitted torque setting means, whereby a coupling force exerted on the starting clutch is altered according to the deviation to make the actual transmitted torque follow up the desired transmitted torque in a feedback manner.
