Abstract

PURPOSE:To reduce the shock when a clutch is disengaged at the time of the speed change by switching the clutch to the disengaged side at the preset timing after the closing operation of the throttle opening is started during the speed change operation. CONSTITUTION:A stroke detecting sensor 7 detecting the connection state of a clutch 2, a vehicle speed sensor 10, an accelerator opening sensor 11, etc., are provided, and their detection signals are inputted to a CPU 17 constituting a timing control means 16 via an I/O 9. Whether the speed change occurs or not is judged based on the pedal depression quantity of an accelerator pedal 12 and the vehicle speed, if the speed change is judged to occur, the delayed action of a timer 17a is started, and a throttle actuator 22 is controlled to fully close the throttle opening from the current throttle opening. When the set time of the timer 17a elapses, a clutch control actuator 6 is operated to switch the clutch 2 to the disengaged side.
