<p>PURPOSE:To perform smooth and speedy speed change control from a current speed change stage to a next speed change stage by performing such control as to set a throttle valve opening to be a little larger opening than a no-load opening by a throttle actuator when an input side engine speed of the next speed change stage synchro-clutch gets closer to an output side engine speed. CONSTITUTION:A speed change actuator A2 releases a current speed change stage synchro-clutch means to be neutral, and in this neutral condition, control of opening of a throttle valve is performed by a throttle actuator A1 to synchronize an input side engine speed of a next speed change stage synchro-clutch with an output side engine speed. After this, when the input side engine speed of the next speed change stage synchro-clutch approaches the output side engine speed, control of setting the throttle valve opening to be a little larger than a no-load opening is performed by the throttle actuator A1, while the speed change actuator A2 performs control of starting engagement action of the next speed change stage synchro-clutch means.</p> |
