ABSTRACT:
An electrically operable clutch is engaged upon opening of a clutch control circuit. The circuit comprises a first switch on a gear shift lever which is closed while the shift lever is pushed away from the driver, a second switch on the lever which is closed while the shift lever is pulled toward the driver, a third, usually closed switch which is opened only when the shift lever reaches a shift position short of either one of the fully pushed position or the fully pulled position, a fourth, usually closed switch which is opened only when the shift lever reaches a shift position short of the fully pushed position and a fifth, usually closed switch which is opened only when the shift lever reaches a shift position short of the fully pulled position, wherein each said shift position short of the fully pulled or pushed position is so determined that synchronizing process in the transmission is substantially terminated in this position. The third, fourth and fifth switches are connected in parallel with one another, while the first and second switches are connected respectively in series with the fourth and fifth switches.
