    摘要: A control system for a vehicle generator comprises a controller for controlling a field current of the generator thereby controlling an output voltage of the generator. The controller is programmed to send to the generator, if vehicle electrical equipments are OFF and the vehicle is not in a decelerating condition, a generation command value that is a first target voltage lower than a normal generation voltage, send to the generator, if the vehicle electrical equipments are OFF and the vehicle is in the decelerating condition, a generation command value that is a second target voltage higher than the normal generation voltage, and send to the generator, if one of the vehicle electrical equipments is ON, a generation command value that is a third target voltage lower than the normal generation voltage and higher than the first target voltage. A control method is also provided.

    摘要: A control device for a motor fan of a vehicle, which controls the motor fan to cool a radiator for engine coolant and a condenser for air conditioner refrigerant, includes: a first command value calculation section which calculates a first command value for control of the motor fan according to refrigerant pressure; a second command value calculation section which calculates a second command value for control of the motor fan according to coolant temperature; a first target value setting section which sets the greater of the first command value and the second command value as a first target value; a second target value setting section which obtains a second target value for control of the motor fan which corresponds to a total torque which is smaller than a total torque of a torque of an alternator and a torque of a compressor corresponding to the first target value; and a control section which controls the motor fan according to the second target value. And the second target value setting section corrects the total torque of the torque of the alternator and the torque of the compressor based upon a predetermined condition when obtaining the total torque of the torque of the alternator and the torque of the compressor.

    摘要: A lamp driving apparatus includes a controller, a lamp driver, a lamp voltage detector, a switch and a switching controller. The controller outputs a switch control signal and a lamp driving control signal in response to an instructing signal for instructing a lamp to be turned on and off. The lamp driver supplies an electric power to the lamp in accordance with the lamp driving control signal. The lamp voltage detector detects a voltage applied to the lamp, and outputs a detecting signal showing the applied state of the voltage to the controller. The switch is connected to the lamp driver, a lamp driving power supply line, and a preliminary power supply line, and switches between a first state and a second state selectively. The first state is a state that the electric power for driving the lamp can be supplied to the lamp driver from the lamp driving power supply line The second state is a sate that the electric power for driving the lamp can be supplied to the lamp driver from the preliminary power supply line. The switching controller controls a switching of the switch in accordance with the switch control signal. The controller outputs the switch control signal so as to make the switch to the first state when the instructing signal for instructing the lamp to be turned on. The controller outputs the switch control signal so as to make the switch to the second state in a case that the detecting signal showing an abnormal applied state of the voltage is received from the lamp voltage detector while the controller outputs the lamp driving control signal for turning on the lump.
