In one example, the park lock may be configured with a first portion having a first set of teeth and a second portion having a second set of teeth configured to engage with the first set of teeth. The first portion may be coupled to a rotating part of the vehicle while the second portion may be coupled to a stationary part of the vehicle. The second portion may include actuating devices to actuate the sliding of the second set of teeth, the actuating devices including a motion source, elastic elements, and one or more ramps.

An actuating mechanism for actuating a gearbox emergency release of a gearbox of a motor vehicle having a parking lock and being mechanically locked by means of the parking lock when the parking lock is activated, having at least one actuating element fixed to the vehicle, by means of which the parking lock can be manually and mechanically deactivated, and having a tool formed separate from the actuating element, by which the actuating element can be manually and mechanically activated for the manual deactivating of the parking lock, wherein the tool comprises a threaded spindle and at least one corresponding movement element, which can be moved by a relative rotation between the threaded spindle and the movement element in translation along the threaded spindle and relative to it, in order to thereby actuate the actuating element.

A compact park lock assembly may be configured to be pulled towards a ramped section of a locking lever during actuation between unlocked and locked positions to unlock and lock a park lock gear. The park lock assembly may include a guide plate configured to perform multiple functions including aligning the park lock assembly during assembly, receiving input loads directly from a pinion drive gear arrangement to improve torque transmission, position and restrain movement of the guide plate between the locked and unlocked positions, and provide for sensing of the position of the locking lever during operation. The compact park lock assembly also may include an abutment plate member which comprises an abutment plate section to facilitate mounting of the compact park lock assembly, a spring section to restrain the guide plate, a clip section to force and retain the abutment plate section to a housing, and fastener features to secure the abutment plate member to a housing. The guide plate and/or the abutment plate member may be formed as a single-piece, integrated component or may comprise a multi-piece component.

A gear locking mechanism includes a gear (or a sprocket wheel) having a series of substantially identical teeth and a locking tongue having a tooth (or teeth) configured in a locked position to engage the gear or sprocket wheel between any two of the series of substantially identical teeth of the gear or sprocket wheel. An anchoring structure restricts a degree of rotation of at least a portion of the locking tongue in the locked position. In the unlocked position, the restriction on the freedom of rotation is released. The locking tongue divided by a fixed pivot includes a movable distal portion of a see-saw having the tooth with the anchoring structure exerting a force against the proximal portion. Alternatively, the locking tongue rotates on a pin on a distal end and the anchoring structure urges a proximal portion toward the gear to lock.

A parking apparatus for a vehicle may include: a piston moved according to whether hydraulic pressure is introduced; a detent lever rotated by the movement of the piston; a sprag disposed on a rotation path of the detent lever, and locked to the detent lever so as to restrict the rotation of the detent lever; and a driver contacted with the sprag, and configured to transfer rotational power to the sprag.

Axial adjustment device (1), comprising a first disk (2) which is rotatable and axially displaceable both in a first circumferential direction (I) and in a second circumferential direction (II), namely a circumferential direction counter to the first circumferential direction (I), and a second disk (3) which is locked against rotation in the first circumferential direction (I) and is rotatable in the second circumferential direction, wherein the second disk (3) has an activating element (8) on its end side facing away from the first disk (2), and wherein the first disk (2) and the second disk (3) each have, on their mutually facing end surfaces, at least three identically formed depressions (4) which lie opposite one another in each case in pairs and thus form at least three pairs of depressions, wherein a rolling element (5) is arranged in each of the pairs of depressions, wherein the depressions (4) each have a slope in the first circumferential direction (I) from a lower dead centre (6) towards an upper dead centre (7), and an actuation arrangement, comprising such an axial adjustment device.

A method for operating a parking lock system (10) with a parking interlock gear (11) is provided. The parking lock system (10) also includes a parking pawl (12) insertable with an insertion section (20) in one of recesses (16) of the parking interlock gear (11) in order to interlock the parking interlock gear (11), a parking lock actuator (13) for the parking pawl (12), and a parking lock sensor (14) for detecting an absolute rotation angle position of the parking interlock gear (11). The method includes detecting an absolute rotation angle position of the parking interlock gear (11) and comparing the detected absolute rotation angle position with a reference rotation angle position. When the particular absolute rotation angle position is situated behind the reference rotation angle position as viewed in the particular direction of rotation of the parking interlock gear (11), a rattling process of the parking pawl (12) is detected.

Provided are an apparatus and a method for parking control of a vehicle and the method includes a step in which a control unit determines a driver's parking intention by receiving a brake signal, pressure of a master cylinder, and a position of a shift lever from a brake switch, a pressure detection unit, and a shift lever detection unit, respectively; a step in which the control unit determines a state of the vehicle by receiving an inclination, a wheel speed, and a vehicle speed from an inclination detection unit, a wheel speed detection unit, and a vehicle speed detection unit, respectively; a step in which the control unit determines a state of an electronic parking brake; and a step in which the control unit operates the electronic parking brake through an EPB driving unit.
