    摘要: A four-wheel drive vehicle provides a torque distribution clutch mechanism which directly transmits the driving force generated from the engine to one of two front wheels or two rear wheels, and which transmits it to the other wheels therethrough in order to control the engaging force in accordance with a traveling status of the four-wheel drive vehicle. The vehicle further comprises a tight corner judging structure, a normal mode setting structure, a low friction road judging structure and a tight mode setting structure. The tight corner judging structure judges whether the vehicle travels at a large turning angle or not, and the normal mode setting structure sets a normal mode to control the engaging force when it is judged by the tight corner judging structure that the vehicle does not travel at the large turning angle. Further, the low friction road judging structure judges whether the vehicle travels on a low friction road or not, and the tight mode setting structure for setting a tight mode to control the engaging force in a condition that it is judged by the tight corner judging structure that the vehicle travels at the large turning angle when it is judged by the low friction road judging structure that the vehicle dose not travel on the low friction road.

    摘要: A power distribution control apparatus determines a command value that corresponds to the driving state of a four-wheel drive vehicle. The vehicle includes a pair of front wheels and a pair of rear wheels, and a coupling device that changes the power distribution to the front wheels and the rear wheels. The control apparatus detects the differential rotation speed between the average rotation speed of the front wheels and the average rotation speed of the rear wheels. The control apparatus estimates the exothermic energy generated in the coupling device based on the product of the differential rotation speed and the command value. The control apparatus determines an optimum drive mode for the four-wheel drive vehicle based on the estimated exothermic energy and for selecting map data corresponding to the determined drive mode. The control apparatus determines the command value that corresponds to the driving state by using the map data.

    摘要: The present invention provides a driving force distributing apparatus which can instantaneously reduce clutch pressure to thereby carry out proper operation of an ABS even if the ABS is actuated in traveling in a 4WD mode. In order to reduce pressure in a piston chamber, a control circuit drives a motor for reverse rotation. As a result, a pressure difference between a piston chamber side pressure and a pump side pressure in a supply path becomes large, pressure oil on a piston chamber side in the supply path is instantaneously discharged to an outside from a releasing hole of a quick open valve, and the pressure in the piston chamber reduces instantaneously.

    摘要: This invention relates to an automatically controlled clutch in a motor vehicle drive train. Rotational speed differences between the clutch input and the clutch output are determined by a computer from rotational speeds of the vehicle engine, on the one hand, and rotational speeds of the vehicle drive wheels, on the other hand. Variations of a frequency which is characteristic of resonant frequencies in the drive train when the clutch is closed are not taken into account.

    摘要: A control unit for a friction clutch or another torque transmitting system and/or for a transmission system in a motor vehicle employs an actor having an electric motor arranged to drive a single-stage or multi-stage transmission which, in turn, transmits motion to one or more mobile parts of the torque transmitting and/or transmission system by way of one or more output elements of the actor. The motor receives signals from one or more sensors and/or from the electronic circuitry in the vehicle and/or from a memory. At least one coil spring and/or another energy storing element is or can be provided to guarantee that the torque transmitting system assumes a predetermined (e.g., disengaged) condition and/or that the transmission system is in a predetermined gear ratio when the actor is not in use to change the magnitude of torque being (or to be) transmitted by the torque transmitting system and/or the ratio of the transmission system.
