US 2022/0063414 A1 · POWER CONTROL APPARATUS AND METHOD FOR AUTONOMOUS VEHICLE

Abstract

A power control apparatus includes: a first power supply device that supplies main power, a second power supply device that supplies auxiliary power, a power divider that divides the main power input from the first power supplier, a first controller connected to a first output terminal of the power divider to control power supply to a first in-vehicle load by connecting or disconnecting the main power and the auxiliary power, and a second controller connected to a second output terminal of the power divider to control power supply to a second in-vehicle load using the main power. The first controller and the second controller diagnose a power failure in cooperation with each other and supply redundancy power using the main power or the auxiliary power based on a power failure diagnosis result.

Dependent claims

A power control apparatus comprising:

a first power supply device configured to supply main power;
a second power supply device configured to supply auxiliary power;
a power divider connected to the first power supply device and configured to divide the main power supply from the first power supply device;
a first controller connected to a first output terminal of the power divider to control power supply to in-vehicle loads by connecting or disconnecting the main power and the auxiliary power;
and
a second controller connected to a second output terminal of the power divider to control power supply to the in-vehicle loads using the main power,
wherein the first controller and the second controller diagnose a power failure in cooperation with each other and supply redundancy power selectively using the main power and the auxiliary power based on a power failure diagnosis result.
