Claim 0:
1. A system for an autonomous vehicle, comprising:
a power supply configured to provide a first power output and a second power output;
a master computer arranged to be powered by the first power output, configured to control operations of the autonomous vehicle in response to detecting the second power output, and configured to provide a third power output by adjusting the first power output;
a slave computer arranged to be powered by the second power output, and configured to control the operations of the autonomous vehicle in response to detecting a failure of the master computer;
at least one millimeter wave radar arranged to be powered by the second third power output and be communicatively coupled to the master computer and the slave computer, the at least one millimeter wave radar configured to acquire a microwave image around the autonomous vehicle and send the microwave image to the master computer and the slave computer; and
at least one camera communicatively arranged to be redundantly powered by the third power output and be communicatively coupled to the master computer, the at least one camera configured to acquire an optical image around the autonomous vehicle and send the microwave optical image to the master computer,
wherein the slave computer is configured to cause the autonomous vehicle to enter a limp mode responsive to a failure of the master computer and, based on a microwave image provided by the at least one millimeter wave radar, cause autonomous vehicle to park in a safe area, and
wherein the master computer is configured to cause the autonomous vehicle to enter the limp mode responsive to a failure of the slave computer, the master computer being further configured to when the autonomous vehicle is in the limp mode:
responsive to failure of the second power output, cause the autonomous vehicle to park in the safe area based on the optical image provided by the at least one camera, and
responsive to failure of the third power output, cause the autonomous vehicle to park in the safe area based on the microwave image provided by the at least one millimeter wave radar.
