Provided is a control device for a vehicle including a continuously variable transmission. The control device includes a lock-up clutch, an oil pump, an electric motor, and a device control unit. The lock-up clutch is disposed in a torque converter coupled to the engine and switchable between an engaged state and a released state. The oil pump is driven by the engine and supplies a hydraulic oil to the continuously variable transmission. The electric motor is coupled to the engine and controlled to be in a powering state in which the engine is rotationally driven. The device control unit controls the lock-up clutch to put into the released state and controls the electric motor to put into the powering state if a discharge pressure of the oil pump falls below a threshold value at the time of a vehicle deceleration in which a fuel supply to the engine is cut off.

Clutch control device for four-wheel drive vehicle

A clutch control device is provided for a four-wheel drive vehicle for transmitting drive force to the rear wheels. The clutch control device includes a dog clutch and a friction clutch, and a controller that controls the engagement and disengagement of the dog clutch and the friction clutch. In this clutch control device, the four-wheel drive hybrid vehicle includes a disconnected, two-wheel drive mode and a connected, four-wheel drive mode. When a driver's foot is lifted off an accelerator in a low-speed region when the connected, four-wheel drive mode is selected, the 4WD control unit maintains the connected, four-wheel drive mode while the brakes are not depressed, and shifts the mode to the disconnected, two-wheel drive mode when the brakes are depressed.

Electronic control of manual transmission clutch

A controller adjust a clutch actuator position is response to movement of a clutch pedal. During an engagement or a disengagement, the controller monitors sensor signals to determine the actuator position corresponding to the touch point. The sensors may directly indicate clutch torque or may respond indirectly. A Giant Magneto Resistive (GMR) sensor provides a precise shaft rotational position signal which can be twice numerically differentiated to yield an accurate and stable acceleration signal. The controller updates the touch point based on a change in the sensed acceleration or torque. The controller then adjusts the relationship of actuator pedal position to clutch pedal position, making mechanical wear adjustment unnecessary.
