<p>PURPOSE:To carry out the smooth clutch control by increasing the clutch torque set value stepwise, having the clutch torque data on the basis of the engine revolution speed and the throttle valve opening degree as aimed value, after an electromagnetic clutch is disconnected for a certain time on the start of a vehicle. CONSTITUTION:The turning moment of an engine 1 is connected/disconnected by an electromagnetic clutch 2 and transmitted to the driving wheels 7 through a reduction gear part 3, continuously variable speed change mechanism part 4, and a differential gear part 6. Further, in the continuously variable speed change mechanism part 4, speed change ratio is varied by varying the internal between a drive side pulley 4 by a motor 4a. The electromagnetic clutch 2 and the motor 4a are controlled by a controller 10 on the basis of the engine revolution speed and the throttle valve opening degree which are detected by the sensors 18 and 19. In this case, if the start state of a vehicle is detected, the electromagnetic clutch 2 is disconnected for a certain time. Then, the clutch torque set value is increased stepwise, having the clutch torque data as aimed value.</p> |
