<p>PURPOSE:To conduct speed shift, in the case of a speed shift command having been outputted, surely and quickly on the basis of this command. CONSTITUTION:When a speed shift signal is received, a throttle valve T is opened fully, and a fuel feed controlling means M2 conducts initial cut control to reduce engine output abruptly into a deceleration state during a time that is from this time to a first set time, and in continuation, conducts intermittent cut control to increase this engine output gradually during a time that is a second set time. Meanwhile, a speed shift actuator A2, on receiving a speed shift signal from a speed shift command means, starts the release operation of a present speed shift step synchroclutch, and completes the release of this present speed shift step synchroclutch when the relationship between the drive side and the driven side of the present speed shift step synchroclutch has fallen into an approximate non-load state in the intermittent cut control, and changeover to a neutral speed shift step is carried out.</p> |
