Abstract
A power supply controller controls the output of a DC/DC converter, so that the power output can be used not only by an electrical power steering apparatus, but by other operating/driving controllers as well. The controller may command the DC/DC converter to reduce the voltage of the high-voltage battery to a prescribed voltage or to boost the voltage of the low-voltage battery to a prescribed voltage when appropriate. In addition, the controller may also command the gradual reduction of the power supplied by the DC/DC converter to the power steering apparatus. The gradual reduction in power prevents a sudden change in the steering feel, which improves drivability of the vehicle.

7. A power supply controller comprising:
-
a main battery that supplies driving power to a drive motor; an electrical driving control device that controls electrical power supplied from the main battery and controls the drive motor; an operating/driving control device that controls an operating/driving condition of a vehicle, includes an electrical actuator powered by the main battery, and controls the electrical actuator; and a voltage conversion device that converts a voltage of the main battery to a voltage that is suitable for use as a power supply for the electrical actuator of the operating/driving control device; wherein the electrical driving control device includes a control command device that is communicatively connected to the voltage conversion device via a communication bus, and that outputs a control command to the voltage conversion device to control a voltage conversion operation of the voltage conversion device. - View Dependent Claims (8, 9, 10, 11, 12)
