Improved rotary switch systems and methods are disclosed. Such systems and methods may be used in vehicles that implement shift-by-wire transmission systems. The switch systems and methods may include programmable end-stops and/or variable tactile feedback.

A vehicle shift control lever device may be provided that includes: a transmission rod; a detent pin which is disposed under the transmission rod in such a manner as to move in up-and-down and back-and-forth directions; and a groove member which has a groove formed therein which guides the detent pin. The groove member includes a first stable position a at which the detent pin is placed when a shift position is R, D, M or N-shift positions and a second stable position b at which the detent pin is placed when the shift position is a P-shift position.

The present invention is directed toward a shift actuator assembly that includes a housing having a retaining mechanism. A holding pawl is biased into engagement with the retaining mechanism. A solenoid releasably engages the pawl when the shift shaft is disposed in its first position such that once the solenoid disengages the pawl, the cam surfaces on the retaining mechanism cooperate with the holding surfaces on the pawl to drive the pawl out of engagement with the retaining mechanism thereby releasing the biasing force of the biasing mechanism to drive the housing and the shift fork axially on the shift shaft between engaged and disengaged positions with respect to the associated gear set.

A transmission emergency release for an automatic transmission which is mechanically blocked when a parking mode is engaged, includes a manually operable actuating element for the mechanical deactivation of the parking mode, wherein the actuating element has a vehicle-fixed mount (1, 29) with a force transmitting element and an actuating lever (9, 25) which is insertable in the vehicle-fixed mount (1, 29) to disable the parking mode in order to disable the parking mode by means of the force-transmitting element.
