<p>PURPOSE:To make a fixed travel 'feeling' possible without relation to the load condition of a vehicle by controlling the slip ratio of a clutch changing in response to the load condition of the vehicle according to a variation slip ratio at the time of making a fork-life truck start. CONSTITUTION:A CPU 18, when it decides that a car speed responding to the stepping-on amount of an accelerating pedal 14 is more than a predetermined speed, controls an actuator 6 through an interface 9 and an actuator-drive-circuit 19 in order to put a clutch 2 to the state of semi-clutching. When a fork-lift truck is stated under a load condition, its load manifests itself as the slip of the clutch 2. The CPU 18 decides this by a difference between a real slip ratio and a standard slip ratio, that is, a variation slip ratio. And, the CPU 18 calculates the regulating quantity of the stroke of a rod 6a according to the variation slip ratio, and controls the actuator 6 through an actuator-drive-circuit 20. And, when a vehicle which has started in the state of semi-clutching reaches the predetermined speed, the clutch 2 is made to be in the state of complete contact.</p> |
