<p>PURPOSE:To prevent an engine stop from the occurring caused by the mistaken connective operation of a clutch by providing an electromagnetic valve for opening and closing a liquid pressure path to change over the electromagnetic valve to the closed condition when the symptom of engine stop phenomenon is detected. CONSTITUTION:When the symptom of engine stop takes place and the rotational frequency of engine is reduced lower than a set value, an electromagnetic valve 1 is operated to shut off liquid pressure path 8. Upon the shut-off of the liquid pressure path 8, the liquid pressure in a release cylinder 9 is maintained, and the connection of clutch is held under such a condition so that the reduction of rotational frequency of the engine is prevented. Thus, when the symptom of engine stop phenomenon takes place, the succeeding connection of the clutch is stopped so that the occurrence of engine stop phenomenon due to the mistaken connective operation of clutch in starting a vehicle can be avoided.</p> |
