An operating position select device has a select lever unit, a mode shift unit to shift operation modes of the automatic transmission, a mechanically connecting means connecting them, and an assist actuator to assist a select lever. A control unit that controls the actuator is electrically connected to an operating position sensor detecting an operating position of the select lever and an operating force sensor detecting operating force acting on the lever. The control unit has an improper halt detecting part detecting the improper halt of the lever between the select positions and an improper halt preventing part preventing the lever from being kept halted improperly between the select positions to provide the lever with adjustment force so that the lever moves to one of the select positions when the improper halt of the select lever is detected during select operation.

Operating position select device for automatic transmission

An operating position select device has a select lever unit, a mode shift unit to shift operation modes of the automatic transmission, and an assist actuator controlled by a control unit. A first connecting member of the select lever and a second connecting member of the mode shift unit 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 are detected by an operating position sensor and an assist position sensor, respectively. The actuator 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.

An operating position select device has a select lever unit, a mode shift unit to shift operation modes of the automatic transmission, a mechanically connecting means connecting them, and an assist actuator to apply assist force to a select lever of the select lever unit. A control unit for controlling the actuator is electrically connected to an operating state sensor detecting an operating state of the select lever. The control unit executes assist control to control the assist actuator based on the operating state signal of the operating state sensor, and maintains the assist control for a predetermined period after the ignition switch is turned to OFF.

An operating position select device for an automatic transmission has a select lever unit having a select lever operated by a driver; a mode shift unit mounted on the automatic transmission to shift operation modes of the automatic transmission; a first and second control cables and others for mechanically connecting the select lever and the mode shift unit, and an actuator for outputting assist torque to shift the mode shift unit. An operating angle sensor detects an operating angle of the select lever and an assist angle sensor detects an assist angle of the assist actuator. A control unit controls a drive current supplied to the assist actuator based on the operating angle and the assist angle.
