摘要： A control unit for an automatic transmission of a vehicle is provided. The vehicle includes a gear selection operating element which allows a user of the vehicle to set different drive positions of the transmission, but not individual gears, by actuating the gear selection operating element. The control unit is configured to determine that a drive position “L” has been set using the gear selection operating element, and in response thereto, the control unit is also configured to provide a graphical user interface on a screen of the vehicle. The user interface allows a manual gear shift of the transmission.

摘要： A shift range control device switches a shift range by controlling the driving operation of a motor in a shift range switching system. The shift range control device includes a drive control unit, a stop control unit, and a return control unit. The drive control unit drives the motor so that an engagement member engages in one of recess portions corresponding to a requested shift range. The stop control unit stops the motor at a target position corresponding to the requested shift range. When the requested shift range corresponds to one of both ends of multiple recess portions, the return control unit returns the rotation position of the motor after the motor stops at the target position.

摘要： A speed change control apparatus includes a shifting operation unit, a speed change controller, a deceleration detector, a gradient acquiring unit, and an allowable revolution number setting unit. The speed change controller changes the speed ratio of the automatic transmission on the basis of a shifting operation received by the shifting operation unit. In a case where the shifting operation unit receives a downshift request during deceleration of the vehicle, the allowable revolution number setting unit sets high-speed downshift allowable revolution number on the basis of the deceleration rate of the vehicle detected by the deceleration detector and the road-surface gradient acquired by the allowable revolution number setting unit. The speed change controller executes downshifting in a case where: the shifting operation unit receives the downshift request during the deceleration of the vehicle; and engine revolution number becomes equal to or smaller than the high-speed downshift allowable revolution number.

摘要： A driver is enabled to, even if a range selected by the driver and an actual range of the vehicle are different from each other, correctly recognize the actual range of the vehicle without occurrence of disagreement between an indicated range and the actual range of the vehicle. A display means is capable of indicating a range irrespective of a rotation operation of a shift member, and a range of the vehicle is capable of being switched to the range irrespective of the rotation operation of the shift member; and an instruction to the display means and an instruction to switch the range of the vehicle are provided from either one of first control means for indication control or second control means for vehicle range switching control.

摘要： At a shift lever device, at a time when a lever is rotated in a left-right direction, a joint of the lever moves a joint tube of a link in an up-down direction. Moreover, at a time when the lever is rotated in a front-rear direction, a link operating portion of the lever rotates an operation tube of the link in the front-rear direction around the joint side. Here, at the time when the lever is rotated in the left-right direction, the joint is moved in the left-right direction with respect to the joint tube. Therefore, the need to provide parts between the lever and the joint can be eliminated, and a number of parts can be reduced.

摘要： A shift device includes: a shift switching member including valley parts corresponding to a shift position; a positioning member provided to establish the shift position in a state of being fitted into any one of the valley parts; a motor including a rotor and a stator and driving the shift switching member; a speed reduction mechanism section rotating the shift switching member in a state in which a rotation speed transmitted from the motor is reduced; a rotor rotational angle sensor detecting a rotational angle of the rotor; and an output shaft rotational angle sensor detecting a rotational angle of the shift switching member. The shift device detects the number of rotations of the motor based on association between output values of the output shaft rotational angle sensor and the rotor rotational angle sensor.
