An automated manual transmission, comprising: a transmission control unit, a shift rod movable between a predetermined first position in which it engages a first gear combination of the transmission, a predetermined second position in which it engages a second gear combination of the transmission, and a predetermined neutral position in which it does not engage any gear, an actuator for moving the shift rod between the first position, the second position and the neutral position by applying a fluid pressure acting on the shift rod in response to signals from the transmission control unit, mechanical engagement means for maintaining the first and second positions of the shift rod without applying any fluid pressure by means of the actuator,
wherein the transmission is adapted to maintain the neutral position of the shift rod solely by applying fluid pressure acting on the shift rod.

Methods and systems are provided for a vehicle park lock. 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.

In a vehicle parking lock mechanism, a parking pawl mechanically hinders rotation of the parking gear by being engaged with the parking gear. A lock member is moved to the lock position to establish a parking lock state in which the parking pawl hinders rotation of the parking gear. The support member includes a guide portion configured to guide movement of the lock member between the lock position and the unlock position while restricting the lock member from displacing in a direction away from the parking pawl. The stopper is rotatably mounted to either one member of the lock member or the support member, changes a posture in accordance with relative movement between the lock member and the support member, and protrudes toward the other member side of the lock member such that the stopper establishes a protruding posture in the parking lock state.

A transmission comprises a moving mechanism to generate axial force to move the one rotary member and releases the axial force according to generation of coasting torque, an urging mechanism to urge the one rotary member with force being poorer than the axial force being generated by the moving mechanism so that the meshing teeth mesh, the contact body of the urging mechanism arranged in a supporting hole formed on the torque transmission member in a radial direction, and an urging and converting part provided to receive the contact body being urged in the radial direction by the urging functional part and convert a direction of the urging to the axial direction to urge the axial movement of the one rotary member.

A shift range control apparatus controls a shift range switching system that switches shift ranges by controlling driving of a motor. This control apparatus calculates a motor angle based on a motor rotation angle signal, acquires an output shaft signal based on a rotation position of an output shaft from an output shaft sensor, sets a target rotation angle based on a target shift range and the output shaft signal, and controls driving of the motor such that the motor angle becomes the target rotation angle. The control apparatus sets the target rotation angle to a target limit value, in response to the target rotation angle that is set based on the output shaft signal being a value at which rotation occurs that is further toward a back side in a rotation direction than the target limit value that is set based on shift ranges before and after switching.

A shift device includes: a shift switching member including valley portions provided so as to correspond to shift positions; a positioning member causing the shift position to be established while being fitted in any of the valley portions of the shift switching member; a motor driving the shift switching member and including a rotor and a stator; a driving force transmission mechanism transmitting a driving force from the motor to the shift switching member; and a rotor rotation angle sensor and an output shaft rotation angle sensor detecting rotation angles of the rotor and the shift switching member. The shift device corrects a deviation from a center of a preset backlash when a backlash width included in the driving force transmission mechanism detected based on output values of the output shaft rotation angle sensor and the rotor rotation angle sensor is a value or more during a shift switching operation.

A gear seeking shifter having a housing containing a shift lever with a depressible inner push rod. A CAM component is rotatably supported to a base of the shift lever and is driven by a gear seeking motor. An upwardly biased gate pawl is secured to the inner push rod into contact with any of a PRND shifter position gates configured along an opposing underside of said housing. At least one detent pawl is supported within the housing in biasing contact with a detent plate configured upon an opposing inside surface of the housing. The CAM component, upon being rotated by the motor, includes each of a first profile for retracting the gate pawl and a second profile for engaging and inwardly displacing the detent pawl away from contact with the detent plate to permit the CAM component to rotate the shift lever to a desired gear position.
