A valve system for a hydraulic emergency driving gear function of a hydraulic control unit for a motor vehicle automatic transmission includes a position valve (104) with a first piston slide (120) and an electromagnetic pressure regulator (86) having a decreasing characteristic curve. The first piston slide (120) is preloaded in a first position. When the first piston slide (120) is in a second position, the electromagnetic pressure regulator (86) is configured for connecting a system pressure-carrying line (18) of the motor vehicle automatic transmission to a first emergency driving gear clutch (12) of the motor vehicle automatic transmission and to a second emergency driving gear clutch (15) of the motor vehicle automatic transmission, whereby the first emergency driving gear clutch (12) and the second emergency driving gear clutch (15) are actuated, so that an emergency driving gear of the motor vehicle automatic transmission is engaged.

A shift range control device switches a shift range by controlling driving of an actuator. A plurality of control units are configured to control the driving of the actuator. A plurality of monitoring control units are correspondingly provided for the plurality of control units, and configured to monitor the corresponding control units. The driving of the actuator is controlled by one of the control units, which is in a normal state. When an abnormality occurs in the one of the control units being used to control the driving of the actuator, the one is switched to another one of the control units to control the driving of the actuator.

A shift range control device is provided for a shift range switching system that includes a motor and a plurality of detectors. The motor has a plurality of winding sets. Each of the detectors is configured to detect a physical quantity that changes in accordance with rotation of the motor. The shift range control device includes a plurality of controllers configured to control switching of a shift range by controlling drive of the motor. Each of the controllers is provided to corresponding one of the winding sets and configured to acquire detection signals from the detectors, determine, based on the detection signals, a calculation signal having a same value between the controllers, and control, based on a target shift range and the calculation signal, a current supply to the corresponding one of the winding sets.

A shift range control device includes: multiple controllers that communicate with each other and control driving of a motor. The multiple controllers share control information, and include a first controller and a second controller. When the control information of the first controller is different from the control information of the second controller, one of the first controller and the second controller is set as a continuation controller, and a different one of the first controller and the second controller is set as a stop controller. The stop controller stops the drive control. The continuation controller performs the drive control of the motor.

A control device for a vehicle including (i) a power transmission device, (ii) a shift operation device that is to be operated by a driver of the vehicle to an operation position corresponding to a shift position of the power transmission device, and (iii) a switching device for switching the shift position of the power transmission device through actuation of an actuator. The control device is configured, upon occurrence of a momentary interruption of a control-device electric-power source that is supplied with an electric power from a vehicle electric-power source, to not perform an initial position learning process for setting a reference position of the actuator, until a shift switching operation for switching the shift position of the power transmission device is performed by a driver of the vehicle.

A back-up control unit of a back-up power source device executes: a battery failure determination process of determining whether or not a battery failure has been detected by a failure detecting unit; when it is determined that battery failure has been detected in the battery failure determination process, a switching instruction determination process for determining, on the basis of an instruction signal from a monitor circuit, whether or not an instruction to switch to a P range has been made by a user; and when it is determined that a switching instruction has been made in the switching instruction determination process, a shifting instruction process for starting power supply from a back-up power source to a shift control unit and instructing the shift control unit to shift to the P range.

Auxiliary transmission actuation mechanism 200 in a power transmission unit of a vehicle includes a transmission actuating gear 202, a gear driven bush 204, a gear actuating means 206, a shift fork 208, a shift rail 210, a clutch control valve actuating arm 212, a rail shifting means 214. The transmission actuating gear 202 is used to drive at least one of an even shaft and an odd shaft which in turn drives an output shaft through gears thereby propelling the vehicle when at least one of a dual clutch unit and a hydraulic system of vehicle is not functioning. The clutch control valve actuating arm 212 is adapted to engage a movable member of a clutch control valve assembly 100V thereby actuating clutch control valve 100V to de-actuate the dual clutch unit.
