REDUNDANT SYSTEM FOR IMPLEMENTING A CONTROLLED STOP IN AN AUTONOMOUS DRIVING SYSTEM

A vehicle includes a driving braking system configured to decelerate the vehicle. The vehicle further includes an electronic parking brake system configured to maintain a position of the vehicle when parked. An autonomous driving controller is configured to autonomously drive the vehicle. The autonomous driving controller is further configured to detect failure of the driving braking system and, in response to detecting failure of the driving braking system, perform a controlled stop using the electronic parking brake system. The driving braking system and the electronic parking brake may receive power from different voltage sources. The autonomous driving controller may be connected to the driving braking system and the electronic parking brake by two busses.
