<p>PURPOSE:To enable quick speed change in a transmission provided with a roller synchronizing mechanism and carrying out change operation under the condition of an engaged clutch by synchronizing the rotational frequencies of a main shaft and counter shaft in a short time. CONSTITUTION:When the rotation frequency of a main shaft SM is larger than the synchronous rotational frequency in the speed change operation through a roller synchronizing mechanism R, the rotational frequency of an engine E is quickly reduced through one of a ignition control means M1 and fuel supply control means M2 to synchronize the rotational frequencies of the main shaft SM and counter shaft SC. Also, when the rotational frequency of the main shaft SM is smaller than the synchronous rotational frequency, the rotational frequency of the engine E is increased through throttle valve control means A1 to synchronize the rotational frequency of both shafts SM, SC.</p> |
