An actuating device for actuating gear shifting units of a manual transmission has deflectable transmission elements assigned to a respective gear shift unit for changing the gear ratio, a movable actuating element, and gear shift elements assigned thereto. The gear shift elements are movable together with the actuating element and are arranged in two gear shift groups. Dependent on a selecting position of the actuating element, the gear shift elements are coupled with coupling means for deflecting the transmission elements by means of a shifting movement. The shifting movement is independent of the selecting movement. The selecting position can be changed in selecting steps that are delimited by a selecting step length. At least one first gear shift element has an interconnected first gear shift length which is greater than the selecting step length.

A shift device includes: a shift switching member including valley portions corresponding to shift positions; a motor including a rotor and a stator and configured to drive the shift switching member; a first drive system including a first control unit configured to control a voltage for driving the motor; a second drive system provided separately from the first drive system and including a second control unit configured to control a voltage for driving the motor; and a positioning member configured to establish the shift positions in a state in which the positioning member is fitted into any one of the valley portions of the shift switching member. The shift device acquires the shift positions when the motor is driven by the voltage output from one of the first and second drive systems to move the positioning member such that the positioning member continuously passes through the valley portions.

A rotary actuator for a shift-by-wire system of a vehicle includes a motor with a motor shaft, an output shaft disposed in parallel with the motor shaft, a speed-reducing mechanism configured to reduce a rotational speed of the motor and transmit the rotation of the motor to the output shaft, and a case housing the motor and the speed-reducing mechanism. The speed-reducing mechanism includes a first speed-reducing portion including a ring gear and a sun gear, and a second speed reducing portion including a drive gear and a driven gear. The drive gear and the driven gear are coaxially disposed with the motor shaft and the output shaft, respectively, to serve as parallel shafts type gears. The drive gear is disposed between the motor and the first speed-reducing portion in an axial direction of the motor.

A drive device includes: an actuator rotating, around a rotation axis, a shift drum having a lead groove formed on an outer peripheral surface; and an angle correction unit correcting a detection value of a rotation angle sensor that detects a rotation angle of the shift drum. The angle correction unit calculates the rotation angle of the shift drum at a reference position as a learning angle based on a correspondence between a displacement amount of a first engaging portion and a change amount of the rotation angle of the shift drum per a predetermined time of rotation of the shift drum at a predetermined speed. Then, the angle correction unit corrects the detection value of the rotation angle sensor based on an amount of deviation between the learning angle and a design angle.

In a vehicle equipped with an engine and a shift control mechanism that switches a shift position by rotating a detent plate with an electric actuator, an electronic control device is an electronic control device including a reference position learning unit that executes a learning of a reference position of the actuator that serves as a reference for switching the shift control mechanism by the actuator when a starting condition that is set in advance is satisfied, and includes a drive wheel rotation suppression unit that suppresses a rotation of a drive wheel of the vehicle while the learning of the reference position is being executed by the reference position learning unit.

In some implementations, a controller may cause a gearbox coupled to a rotor to shift between a first gear ratio and a second gear ratio one or more times. The controller may obtain a first set of position data that identifies respective first positions of a gear selector of the gearbox for each shift to the first gear ratio, and a second set of position data that identifies respective second positions of the gear selector of the gearbox for each shift to the second gear ratio. The controller may determine a first calibrated position of the gear selector for a shift to the first gear ratio based on the first set of position data and a second calibrated position of the gear selector for a shift to the second gear ratio based on the second set of position data.

A method for hysteresis compensation in an actuator and a selector fork that is adjustable by this actuator and guides a sliding sleeve, by means of a state machine, wherein the selector fork is moved by means of the actuator from a first shift position (xDecoup), namely a neutral position, into at least one second shift position (xCoup), namely a gear position, and vice versa, wherein the position of the actuator (phiAtr, phiCoup, phiDecoup), in the event of a shift request into the neutral position (xDecoup) or into the gear position (xCoup), is corrected on the basis of stored mechanical backlash (phiBL) between the actuator and the selector fork and of a sign (+1, 0, −1) generated by the state machine and associated with the particular shift request.

A shift mechanism configuring an outboard motor comprises: an electric actuator that linearly moves a movable rod; and a shift shaft portion that switches from neutral to forward or reverse based on displacement of said movable rod. Moreover, a neutral adjusting mechanism enabling a neutral position of the shift mechanism to be adjusted is provided facing the shift shaft portion, by a separate body. The neutral adjusting mechanism, which comprises first and second adjusting arms that are supported in a freely rotating manner with respect to a frame and that have been biased in contrary directions to each other by elastic springing force of a coil spring, is provided in a manner that an adjusting screw mounted in the first adjusting arm capable of abutting on a shift arm always abuts on a contacting wall of the second adjusting arm capable of contacting a switch sensor.

In some implementations, a controller may cause a gearbox coupled to a rotor to shift between a first gear ratio and a second gear ratio one or more times. The controller may obtain a first set of position data that identifies respective first positions of a gear selector of the gearbox for each shift to the first gear ratio, and a second set of position data that identifies respective second positions of the gear selector of the gearbox for each shift to the second gear ratio. The controller may determine a first calibrated position of the gear selector for a shift to the first gear ratio based on the first set of position data and a second calibrated position of the gear selector for a shift to the second gear ratio based on the second set of position data.

An axle assembly having a drive pinion, a transmission, and a shift collar. The transmission may include a set of drive pinion gears. The shift collar may be rotatable about an axis with the drive pinion and may be moveable along the axis with respect to the drive pinion to selectively connect a member of the set of drive pinion gears to the drive pinion.
