摘要:
A structure of an A/T (automatic transmission) control device for a vehicular transmission is disclosed in which when the shift lever (1) for controlling the A/T is pivoted at a position at which a positioning pin (7) is engaged with a parking range P, a solenoid pin (15a) pushed and rotates a rotary bush (14) supported on a peripheral surface of a rotary bush by means of a force of a spring within the solenoid (15) so that a recessed groove (14a) of the rotary bush (14) is deviated from a position of the positioning pin (7). Therefore, even if control button (13) (installed at an upper end of the shift lever (1)) is operated, the positioning pin (7) interferes with the upper plane of the rotary bush (14) and is not lowered any more. Consequently, no deviation from the range P occurs. Next, when a vehicular ignition switch (22) is turned to ON and foot brake is operated, the solenoid (15) is turned to ON. The solenoid pin (15a) pulls and rotates the rotary bush (14) against the spring force of the spring installed within the solenoid so that the position of the recessed groove (14) of the rotary bush becomes the same as the position of the positioning pin (7). When the control button (13) is operated, the positioning pin is moved out of the P range. Thus, it becomes possible to move the shift lever (1) at any one of the ranges other than the P range. The solenoid (15) is again turned to OFF a constant period of time after the solenoid is turned to ON with the foot brake is depressed.

A mechanism is provided for controlling vehicle ignition lock (4) and transmission shift lock (1) in an interlocked relation to each other. The mechanism comprises a lock member (5) movable into a lock position for blocking up a passage (37) to a Park position of a position plate (3). An operating member (6) drives the lock member (5) into the lock position in response to upward movement of a position pin (21) in the Park position. A stopper (41) of an ignition lock is movable between a lock position for preventing rotation of a key rotor into a lock position and an unlock position for allowing the same. A cable (7) interconnects the lock member and the stopper to allow them to move in unison such that movement of the lock member into the lock position causes the stopper to move into the unlock position and movement of the stopper into the lock position causes the lock member to move into the unlock position. A spring (44) is installed in the ignition lock for urging the stopper toward the lock position.

In an automatic transmission shift control device, a rocking lever and a second biasing unit are provided for holding a selector lever (10) in a shiftable condition when the selector lever is in one of gear positions other than a parking position. A first biasing unit (37) is provided for holding the selector lever in a locked condition when the selector lever is in the parking position. A solenoid (30) is provided for releasing the selector lever from a locked condition when energized. The solenoid is energized only when a brake pedal is fully depressed under a condition where an ignition key is in an "ON" position and the selector lever is in the parking position.

A position pin (20) is pushed down by an effort applied on a control button (27) to disengage the position pin from a position plate (18) when a selector lever (10) is to be moved from a parking position to other gear positions. A bushing (28) is mounted on a post (14) of the selector lever for rotation but against axial movement. The bushing (28) has at the upper end a pair of diameterically opposed notches (29) with which the position pin (20) is engaged when pushed down to effect the above disengagement. When an ignition key (43) is at the "ON" position and the selector lever (10) is at the parking position, the bushing (28) is rotated into a position where the notches (29) are misaligned with the position pin unless a brake pedal is fully depressed, i.e., an effort applied on the control button (27) for pushing the position pin (20) downward is received by the upper end of the bushing whereby downward movement of the position pin for disengagement thereof from the position plate (18) is prevented by the bushing (28) and therefore it is impossible to move the selector lever (10) from the parking position to other gear positions.
