Abstract: A method for optimizing kinetic energy for an automobile, using an intelligent clutch (i-clutch) system, comprises dynamically receiving, at a controller [210], one or more parameters from at least one of a braking pressure sensor [202], a speed sensor [204] and an acceleration pressure sensor [206] of the automobile. Next, the controller [210] continuously determines an operating condition of the automobile based on the received one or more parameters. Subsequently, the controller [210] generates a trigger based on the determined operating condition of the automobile to activate an intelligent clutch (i-clutch) [212]. Lastly, the i-clutch [212] disconnects a prime mover and a driving shaft of the automobile, by disconnecting a transmission of the automobile and the driving shaft, to optimize kinetic energy of the automobile.

Abstract: A control apparatus for a power transmission system is provided. The control apparatus includes an electronic control unit. The electronic control unit is configured to, when a discharge flow rate of a mechanical oil pump is smaller than a predetermined flow rate and an electric oil pump is being driven while a vehicle is traveling, determine whether a decrease in the operating hydraulic pressure has occurred. The electronic control unit is configured to, when a first engagement device is controlled from a released state toward an engaged state, control a first control pressure such that the first control pressure in a case where a decrease in a operating hydraulic pressure has occurred is lower than the first control pressure in a case where a decrease in the operating hydraulic pressure does not occur.

Abstract: A clutch control device is provided for a 4-wheel drive vehicle. The clutch control device includes a 4WD control unit that controls the engagement and release of a friction clutch and a dog clutch which are arranged separately in the two paths. The 4WD control unit has a synchronization speed control unit, and at a time of transition from a disconnected, two-wheel drive mode, in which the friction clutch and the dog clutch are released, to a connected, four-wheel drive mode, in which the friction clutch and the dog clutch are engaged, the synchronization speed control unit reduces a synchronization speed of the dog clutch more during vehicle deceleration than when the vehicle is not decelerating.

Abstract: 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.
