摘要： An abnormality detection apparatus, which reduces erroneous detection of an open abnormality of a relay, includes a microcomputer that activates the relay and determines whether the output voltage of the relay is less than a threshold value. When the output voltage is less than the threshold value, the microcomputer repeats the activation of the relay and the determination. The detection unit detects the occurrence of an open abnormality when the repetition number exceeds two.

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 tow 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 means, a normal mode setting means, a low friction road judging means and a tight mode setting means. The tight corner judging means judges whether the vehicle travels at a large turning angle or not, and the normal mode setting means sets a normal mode to control the engaging force when it is judged by the tight corner judging means that the vehicle does not travel at the large turning angle. Further, the low friction road judging means judges whether the vehicle travels on a low friction road or not, and the tight mode setting means for setting a tight mode to control the engaging force in a condition that it is judged by the tight corner judging means that the vehicle travels at the large turning angle when it is judged by the low friction road judging means that the vehicle dose not travel on the low friction road.

摘要： A torque distribution control device for a four-wheel drive vehicle is disclosed having a torque distribution device for distributing the drive power transmitted from an engine to either of the front wheels or the rear wheels as prime drive wheels, to other wheels as sub-drive wheels. In the control device, abnormality judgment means judges whether or not an abnormality is involved in wheel speed signals which are input from wheel speed sensors associated respectively with the front and rear wheels. Means is further provided for altering a normal-state method of calculating a command torque which is applied to the torque distribution device to vary the drive power transmitted to the sub-drive wheels, to an abnormal-state method of calculating the command torque based on data which does not include one wheel speed signal involving the abnormality when the same occurs with one of the wheel speed signals, whereby the vehicle is enabled to continue the four-wheel drive even when the abnormality occurs.

摘要： A temperature sensing apparatus comprises a temperature sensor, a current measuring device and temperature detection circuit. The temperature sensor contains a thermal resistor that is disposed near a motor and outputs voltages acting to the thermal resistor. The current measuring device measures quantity of current that is applied to the motor. The temperature detection circuit detects temperature of the motor according to the output voltages from the temperature sensor. And, the temperature detection circuit judges whether a predetermined quantity of current is applied to the motor during a predetermined time. When the predetermined quantity of current is applied to the motor during the predetermined time, the temperature detection circuit compares a temperature detected by the current measuring device with a predetermined temperature. When the detected temperature is lower than the predetermined temperature, the temperature detection circuit decides a wire of the thermal resistor breaks.
