A shifter assembly includes an electronic shifter mechanism having a shift lever movable between a plurality of gear positions and an electrically powered drive system operatively connected to the shifter mechanism to selectively move the shifter mechanism between a first location wherein the shifter lever is located substantially within a housing and a second location wherein the shifter lever is located substantially outside the housing. The drive system moves the shifter mechanism along a vertical, linear path substantially parallel to a longitudinal axis of the shift lever such that the shift lever moves through an opening in the housing.

The invention discloses a chipless forming method for a gear stick and a section gear through hot extrusion by utilizing an alloy steel horizontal type backward extruder, solving the problems that the existing gear cutting process has more working procedures, low efficiency, large metal loss, more operators for machine tool processing and high production cost and the like by utilizing the chip processes of lathing, milling, drilling, inserting and grinding. The method comprises the following steps: an inner cooling combined type double-conical surface gear squeezing die, a recipient and a floating pecker combined mandril are adopted by taking the producing principle of alloy steel thick wall special seamless steel tubes as an example; scale-free heating is rapidly carried out on the blank; lubricating warm-extrusion molding is carried out; center punching, shaft hole slotting and tooth surface extrusion are finished at a time; and the finished product of the gear stick is directly produced, then is subject to waste heat annealing, slicing by wire-electrode cutting and heating process to be manufactured into a finished product. Compared with a chip gear-cutting molding method, the invention has simplified working procedure, few labor, high efficiency, less metal loss, high gear strengthen and reduces the production cost, and then tooth surface precision reaches the standard. The method of the invention is a significant technological innovation of straight tooth and oblique tooth cylindrical gear process technologies.

A vehicle includes a front-wheel drive (FWD) transmission having a case, a selectable one-way clutch (SOWC) indexed to the case, pressurized fluid, and a valve body assembly (VBA). The VBA has a piston in communication with the fluid, a return spring, and an actuator plate in continuous contact with or connected to each of the piston and a shift lever of the SOWC. Fluid moving the piston and plate in one direction locks the SOWC to enable a reverse mode, and the spring moves the piston and the plate in another direction to unlock the SOWC in a forward mode. A method prevents spin losses in the FWD transmission by positioning a two-mode SOWC within a case, positioning a VBA adjacently and externally to the case, and admitting pressurized fluid into the VBA to engage the SOWC only during a reverse operating mode.

A shifter includes a powered pawl mechanism that selectively engages a shift gate. The powered pawl mechanism may include an electrically operated solenoid or the like, and may be mounted to the base of the shifter or to the shift lever. The pawl engages a shift gate that is mounted on the other of the shift lever and the base. A mechanical override may be utilized to disengage the pawl. The shifter includes an electrically operated push button or the like on the shift knob, and may utilize sensors that determine the shift lever position for controlling a transmission.

An apparatus for returning a transmission to a primary mode is provided. The apparatus includes a shift lever that is configured to shift a transmission and a motor that is configured to provide driving force to move the shift lever. In addition, a selecting unit receives the driving force from the motor and moves the shift lever in a selecting direction. A shifting unit receives the driving force from the selecting unit and moves the shift lever in a shifting direction. The shift lever is further configured to be moved to a first position by the selecting unit and to a second position by the shifting unit.

An electric power steering system includes a control for providing a calculated torque assist demand in the event of failure of a steering wheel torque sensor. The control is responsive to one or more of a vehicle speed, a steering column position, a steering column velocity, a gear lever position, a vehicle yaw rate and a vehicle lateral acceleration for generating the calculated torque assist demand. The control is operable to modify the torque assist demand by providing one or more of (a) friction and inertial compensation, (b) vehicle oversteer compensation, (c) reverse motion compensation, (d) damping compensation and (e) self steer prevention.

In the parking assist apparatus disclosed here, when the side parking mode switch is set at the initial stop position A, the controller calculates the backward movement start position B for parking based on the yaw angle and the steering angle of the vehicle, and upon determining the vehicle Guidance information is issued to stop the vehicle when the calculated backward movement start position B has been reached. After having sensed that the shift lever is shifted to the reverse position, the controller displays on the display an image captured by the camera about the area behind the vehicle, and the vehicle moves backward while maintaining the steering angle at the shift lever shift Next, the estimated vehicle space is also shown in an overlay on this display. The driver operates the steering wheel to establish an appropriate positional relationship between the estimated vehicle space and the target parking space on the display, thereby obtaining an appropriate steering angle in the backward moving vehicle.

The invention belongs to the field of manual transmissions and particularly relates to a gear shifting mechanism of a manual transmission. The gear shifting mechanism of the manual transmission comprises a gear shifting drum, a transmission shell, a guide groove structure and a gear shifting fork structure, the gear shifting drum rotates to enable gear shifting forks in the gear shifting fork structure to alternately ascend and descend along guide grooves, the gear shifting fork structure disengages a gear or engages a gear once by means of each ascending and descending action, one-gear movement of a shifting lever includes one gear disengagement action and one gear engagement action, and the gear shifting process is changed into clutch disengagement-shifting lever gear shifting-clutch engagement, so that the gear shifting process is simplified, and gear shifting time is shortened.

Gear shift arrangement for a shiftable manual gearbox (300) provided in a vehicle, e.g. an off road vehicle, scooter or snowmobile, comprising a shift operating mechanism (9, 8) to be operated by a driver, said gearbox having a first set of gears with positions for high speed, and at least one further gear from the group of gears low speed, neutral and parking, and a second set of gears with positions for at least forward and reverse. The positions of the first set of gears are shiftable under influence of a first shift lever (9), that the positions of the second set of gears are shiftable under influence of a second shift lever (8) separate from the first one, and each shift lever is movable in essentially only one plane.

A device for controlling ISG logic is mounted in a vehicle equipped with an ISG system. The device includes a brake pedal switch, a shift lever switch that shows the current state of a gear of the vehicle, an inclination sensor that is mounted in the vehicle and measures the inclination of a road where the vehicle is positioned, a controller that internally controls the vehicle to an N (Neutral) state, regardless of the gear range shown by the shift lever switch, for the vehicle on a downhill, in accordance with the measured inclination, and an engine unit that performed idle stop when the brake pedal becomes ON, with the gear of the vehicle at a D (Drive) sate, and restarts the stopped engine when the brake pedal becomes OFF, with the gear of the vehicle at the D state.
