<p>PURPOSE:To make a fork-lift truck start smoothly at all times by controlling a clutch into the state of semi-clutching until a car speed reaches a predeter mined one without relation to the stepping-on amount of an accelerating pedal at the time of making the fork-lift truck start. CONSTITUTION:When a forward-backward lever 16 is operated to a forward position by having an engine 1 driven, a CPU 17 controls an automatic speed changer 3 into the gear position of a forward 1 speed. And now, an accelerating pedal 13 is stepped on, then the CPU 17 turns to a starting mode and reads the data of a program memory 18, and commences the control of a clutch- controlling-actuator 6. When the CPU 17 decides that a car speed responding to the stepping-on amount of the accelerating pedal 13 is less than a predetermined one, it controls the 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. And, a fork-lift truck, when it commences its starting with the clutch 2 in the state of semi-clutching, and its car speed reaches the predetermined one, turns its traveling into an ordinary one by the control of the CPU 17.</p> |
