A saddle-type vehicle includes a power unit including a multistage transmission having a plurality of gear positions, a transmission actuating mechanism for changing the gear positions, a shift spindle as an input shaft of the transmission actuating mechanism, a crankcase housing therein the multistage transmission and the transmission actuating mechanism, and a crankcase cover covering a side portion of the crankcase. The shift spindle is disposed in the periphery of the crankcase cover and is coupled to a shift actuator mounted on the crankcase cover by a joint rod. Such saddle-type vehicle having a power unit with a shift spindle movable by a shift actuator, in which the shift spindle and the shift actuator are combined with each other in a small-size layout with a joint rod joining the shift spindle and the shift actuator to each other, allows the joint rod to be installed in position with ease.

A gear shifting mechanism includes a drive motor, a shifting drum, and a first shifting mechanism. The first shifting mechanism includes a first shifting fork, an inner shaft, an outer hub, a first coupling pin, and an elastic component. The elastic component is sleeved on the inner shaft and is located between the inner shaft and the outer hub. There is a first limiting portion and a second limiting portion between the outer hub and the inner shaft. The elastic component is located between the first limiting portion and the second limiting portion. The first limiting portion is connected to one of the outer hub and the inner shaft, and the second limiting portion is connected to the other of the outer hub and the inner shaft.

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 vehicle gear-shifting control apparatus is equipped with an engine, an automatic transmission, and a controller which changes a shift stage by outputting a gear-shifting signal in accordance with the rotation speed of an input shaft to the automatic transmission. The controller executes a torque-regulating control of temporarily increasing or decreasing an input torque input to the input shaft during a shift-change, and when executing the control, determines whether or not a target increase/decrease amount of the input torque can be realized based on calculation results of a target output torque and a target gear-shifting time, executes the control to realize the target amount when it is determined that the target amount can be realized, and executes the control based on an allowable gear-shifting time set in advance to be longer than the target gear-shifting time when it is determined that the target amount cannot be realized.

A range switching apparatus of a shift-by-wire system has: a main motor; a deceleration mechanism that amplifies torque generated by the main motor; an output shaft that outputs the torque amplified by the deceleration mechanism; an auxiliary motor; and an emergency drive mechanism. The emergency drive mechanism is disposed on the auxiliary motor shaft of the auxiliary motor, and that is connected to or disconnected from the deceleration mechanism by driving of the auxiliary motor. The emergency drive mechanism transfers output of the auxiliary motor to the deceleration mechanism, and rotates the output shaft by being connected to the deceleration mechanism.

According to the invention, a further actuating element for actuating a switching device is provided, which further actuating element is operatively connected to the first actuating element, and a transmission device with a transmission element is provided between the first actuating element and the actuating element of the switching device.

An actuator to set a park lock of an automatic transmission of a motor vehicle has a drive (2) driving a drive shaft (1), a first actuating element (3) operatively connected to the drive shaft (1) for actuating a switching device, a spring element (5), which is supported on one side on a housing component (16) of the actuator, and on the other side on a second actuating element (17) designed to load the spring element (5). The actuator also has an electromagnetic retaining device (32) with an electromagnet (50) which interacts magnetically with a magnetic armature (52) comprising a ferromagnetic material component to retain the spring element (5) which is under loading, building up a spring return force. The magnetic armature (52) is mounted tiltably and/or pivotably on a pivot component (55) of the retaining device (32).

A method for the dynamically expanding play correction according to a method for hysteresis compensation for an actuator and for a shift fork which is movable by this actuator via an electric motor having a rotor and a stator and which guides a gearshift sleeve, by means of a cellular automaton, wherein a torque ripple of the actuator and a mechanical displacement of the gearshift sleeve are compensated independently of one another or in combination by means of a learning algorithm.

In a shift lever device, a drive motor is driven such that a second worm wheel is rotated in order to pivot a shift lever toward a P position side. When a detection device has detected that the shift lever is about to be pivoted to the P position, a stopper mechanism is actuated such that a link is moved. When the shift lever has been pivoted to the P position, the link is fitted into a stopper notch in the second worm wheel, thereby stopping rotation of the second worm wheel. This thereby enables the shift lever to be stopped appropriately at the P position.
