ACTUATOR FOR THE ACTUATION OF AT LEAST ONE MOVABLE MEMBER, IN PARTICULAR FOR CHANGING GEAR RATIOS IN A MOTOR VEHICLE TRANSMISSION
An actuator for the actuation of at least one movable member of a motor vehicle transmission. The actuator includes a housing and a cover defining an internal volume in which are received at least one electric motor having a stator and a rotor mounted on a rotor shaft extending along an axis X1, a motor pinion fixed to the opposite end of the shaft to the rotor, a reduction mechanism driven by the motor pinion, a pin mounted so as to be able to rotate at the end of a shaft extending along an axis X3 and able to be engaged in the movable member of the transmission. The shaft of the pin is rotationally guided by a rolling bearing and a slide bearing.

GEAR SEEKING POLYSTABLE SHIFTER
A gear seeking shifter including a housing containing a shift lever with a rotatable base and outer tube supporting a depressible inner push rod. A CAM shaft component is driven by a gear seeking motor. An upwardly biased gate pawl located in the inner push rod contacts with any of PRND shifter position gates configured along an opposing underside of the housing. At least one detent cartridge contains a pawl supported within the rotatable base of the shift lever in biasing contact with a detent plate profile configured upon an opposing inside surface of the housing. The CAM shaft component, upon being rotated by the motor, includes each of a first profile for retracting the gate pawl and a second profile for inwardly displacing the detent pawl away from the detent plate profile to permit the CAM component to rotate the shift lever to a desired gear position.

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.
Shift range control device
A motor angle calculation unit acquires from a motor rotation angle sensor a motor rotation angle signal corresponding to a rotational position of the motor, and calculates a motor angle based on the motor rotation angle signal. An output shaft signal acquisition unit acquires, from an output shaft sensor that detects a rotational position of an output shaft, an output shaft signal corresponding to the rotational position of an output shaft. An abnormality determination unit determines abnormality in the output shaft sensor. A target angle setting unit sets a target rotation angle corresponding to a target shift range. A drive control unit controls driving of the motor so that the motor angle becomes a target rotation angle. The target angle setting unit sets the target rotation angle to different values when the output shaft sensor is normal and when the output shaft sensor is abnormal.

Transmission-equipped vehicle
A controller drives a shifting actuator to move a first engagement member from an original position of a first engagement portion in one direction along a relative motion path and acquires first position information representing a first position, the first position being a position where the first engagement portion moved in the one direction contacts a second engagement portion. The controller drives the shifting actuator to move the first engagement member from the original position in the other direction along the relative motion path and acquires second position information representing a second position where the first engagement portion moved in the other direction contacts the second engagement portion. The controller calculates a center position of the first engagement portion on the relative motion path from the acquired first position information and the acquired second position information, compares the calculated center position to the original position.
Vehicle drive device and control device
A vehicle drive device (1) is disclosed that includes a shift detent mechanism (90); an actuator (74) that generates drive power for allowing the shift detent mechanism to operate; a sensor (135) that generates sensor information indicating an amount of operation of the shift detent mechanism; a control part (153) that controls the actuator; and a clutch (30) that is synchronized with operation of the shift detent mechanism, and when the control part changes a state of the clutch, the control part performs feedback control of the actuator based on a relationship between a target value for an amount of operation of the shift detent mechanism and the sensor information, and before completing the change in the state of the clutch, the feedback control ends and operation of the actuator stops.
