A vehicular parking lock mechanism includes a parking gear, a parking pole, a lock member, and a lock releasing member. The parking pole includes a first parking pole member having a meshing tooth, and a second parking pole member having a cam protrusion. When the lock releasing member is pulled in one direction, and the second parking pole member is moved to a manually released position, the cam protrusion is disengaged from a second roller of the lock member, and the meshing tooth of the first parking pole member comes out of the parking gear, so that the parking lock mechanism is released from the parking locked state.

In one aspect, the present disclosure provides a parking brake device for a motor vehicle. The device may include a vehicle transmission including a parking lock and a gear selector lever coupled with the parking lock, where the gear selector lever is movable into a parking lock position for engaging the parking lock, and where the gear selector lever is movable out of the parking lock position for disengaging the parking lock. A first mechanical transmission element and a second mechanical transmission element may be arranged between the gear selector lever and the parking lock, where the first mechanical transmission element may be connected with the gear selector lever and configured for transmitting a moving force emanating from the gear selector lever to the second mechanical transmission element, and where the second mechanical transmission element may be connected with the parking lock.

A parking pawl module includes a first actuator, a gearbox including at least one gear carrier where the at least one gear carrier supports a hub configured to rotate when the first actuator rotates, and a disconnect module. The disconnect module includes: an output coupler having a first surface and a second surface; an actuation feature disposed on the first surface; and a torsion spring having a first end connected to the output coupler and a second end connected to the hub or the at least one gear carrier. The disconnect module also includes an actuation mechanism disposed on the second surface of the output coupler. The actuation mechanism is configured to mesh with the hub. The first actuator controls movement of the at least one hub, the actuation feature, and the actuation mechanism.

The present rotary shifter includes a rotary locking mechanism, a feel positioner mechanism, and a return-to-home-position (park) mechanism that causes the shifter/rotor to remain locked in park while the locking mechanism resets after the shifter is returned to park. The design allows any number of locking positions based on a height of the drum cam and a position of the follower. As illustrated, a dial-type rotor is moved into home position by pusher features on the drum cam and an actuator motor, while the feel positioner is disengaged, thus allowing for a smoother rotary movement. Once in the home (park) position, a lock ring (also called “follower”) is forced upwards by a spring (or other method) and rides on a track at a different height than the original, therefore keeping it engaged in the rotor until the drum cam rotates back to its locking position.

A parking lock-releasing device for a vehicle, which is capable of improving workability in manually releasing a parking lock while ensuring sealing performance of an outer casing, and easily holding the locking released state. The locking release operation section includes a base having a hollow cylindrical guide portion and concentrically continuous with a front end of the outer casing, with a female screw formed on an inner peripheral surface thereof, and an operating section body which is screwed via a male screw formed on an outer peripheral surface thereof into the female screw of the guide portion, closes the guide portion, holds a front end of the inner cable, and when releasing the locking, is rotatingly operated in a predetermined direction relative to the base, to thereby cause the inner cable to slide to be pulled in the direction away from the parking mechanism.

A park lock apparatus and control unit for a vehicle, the apparatus comprising: a locking member (28, 30; 50) having: a first state arranged to permit independent rotational movement of front and rear drive shafts (20, 22) of the vehicle relative to a fixed position on the vehicle; a second state arranged to prevent independent rotational movement of the front and rear drive shafts of the vehicle relative to the fixed position on the vehicle; and a third state arranged to prevent rotational movement of the front and rear drive shafts of the vehicle relative to the fixed position on the vehicle, and an actuation member (36; 64) for moving the locking member between the first, second and third states.

A locking arrangement for a transmission of a motor vehicle, comprising a locking toothing; a locking pawl, wherein the locking pawl is pivotable about a first rotary axis; a control element, wherein the locking pawl can be brought optionally into engagement with the locking toothing via the control element; a drive unit, wherein the control element can be brought by means of the drive unit into a release position and a locking position; a holding mechanism, wherein the control element can be held by means of the holding mechanism in the release position and in the locking position; and a safety mechanism comprising an electromagnet, an actuator and a first elastic element, wherein the actuator is pretensioned in a first actuator position by the first elastic element and can be held in a second actuator position by the electromagnet.

In one aspect of the invention there is provided a method of manually releasing power actuated vehicle park means in the absence of power, the method comprising the steps of: rotating a power actuated selector shaft from a park mode position in which one or more wheels are locked by the park means to a park release mode position in which the one or more wheels are released by the park means; and locking the selector shaft in the release mode position by means of locking means, whereby the successive steps of rotating the selector shaft to the release mode position and subsequently locking the selector shaft in the release mode position comprise manual translation or rotation of one or more members in first and second directions respectively, the first direction being different from the second direction.

A lever (3) for the temporary disengagement of a parking lock (2) of a vehicle drive unit (1). The lever (3) comprises a fixing piece (31) for fitting the lever (3) onto a parking lock shaft (26), which extends inside the vehicle drive unit (1) and serves to actuate the parking lock (2). The lever (3) is a hand lever with a gripping handle (32). The gripping handle (32) is designed to enable a user to apply a manual force for manual actuation of the lever (3). When the lever (3) is fitted on the parking lock shaft (26) and moved, the parking lock shaft (26) is moved from an engagement position to a disengagement position,. In the disengagement position, by further movement of the gripping handle (32) into a locking position, the lever (3) is blocked against a reverse movement out of the disengagement position.

A system for maintaining a vehicle including a shift-by-wire transmission in a neutral-hold mode is provided. The system includes a transmission control unit in signal communication with the shift-by-wire transmission and an internal control unit of the vehicle. The transmission control unit is configured to control a gear configuration of the shift-by-wire transmission. An external control unit is in signal communication with the transmission control unit. The external control unit is configured to transmit a neutral-hold mold activation signal.
