Operating position select device for automatic transmission

摘要

An operating position select device (1) has a select lever unit (100), a mode shift unit (500) to shift operation modes of the automatic transmission (5), and an assist actuator (2, 9) controlled by a control unit (3). A first connecting member (13) of the select lever (11) and a second connecting member (17) of the mode shift unit (500) are relatively movable to a limit amount to each other and integrally movable beyond the limit amount with each other. The positions of the members (13, 17) are detected by an operating position sensor (61) and an assist position sensor (62), respectively. The actuator (2, 29) is driven so that a difference between an operating position and an assist position may be reduced, but prohibited from driving when the difference is kept out of a permissible range for a predetermined period during rest of the actuator (2, 9).
