PREVENTION OF ENGINE STOP FOR AUTOMATIC TRANSMISSION

Japanese Patent JPS61220940

A

PURPOSE:To certainly stop the inadvertent engine-stop by cutting-off a frictional clutch when the engine revolution speed is less than a prescribed engine-stop preventing revolution speed and setting relatively large the above-described preventing revolution speed in the case when an acceleration pedal is not stepped-in. CONSTITUTION:In an automatic transmission, a frictional clutch 31 which connects and disconnects the output shaft 30a of an engine 30 and the input shaft 44 of a gear type transmission 32 is operation-controlled by an air cylinder 42, and the gear position of the gear type transmission 32 is switching-controlled by a gear shift unit 51. Such automatic transmission is controlled by a control unit 52 so that the frictional clutch 31 is cut-off when the engine revolution speed detected by a revolution speed sensor 39 is less than a prescribed engine- stop preventing revolution speed. At this time, the above-described preventing revolution speed in the case when an accelerating pedal 37 is not stepped-in is set larger than the engine-stop preventing revolution speed in the case when the accelerating pedal 37 is stepped in or on start.
