<p>PURPOSE:To remove uncomfortable deceleration feeling due to the sudden fall of axial torque, by starting return in the totally-closing direction of a throttle prior to the releasing of a main clutch if the throttle is opened not less than intermediate opening when the titled car is automatically speed changed. CONSTITUTION:A computer 44 computes car speed, the number of the revolution of an engine, the quantity of an accelerator stepped, speed change location signals, etc., and speed changes a transmission 1. When a throttle valve 21 is opened not less than intermediate opening by means of the accelerator 37, solenoids 28a, 29a are energized and the throttle valve 21 is throttled up to the intermediate opening of opening corresponding to the quantity of the accelerator pedal 37 stepped before a moment when the releasing operation of a main clutch 7 is started by the energizing of a solenoid 17a. After the throttling action of the throttle valve 21 is once interrupted, the main clutch 7 is disengaged while the throttle valve is totally closed, and the transmission 1 is speed changed.</p> |
