Abstract

Systems and methods for brake redundancy for an autonomous vehicle are provided. An autonomous vehicle braking system can include a primary brake control module comprising one or more processors. The primary brake control module can be configured to brake an autonomous vehicle in response to receiving a braking command from a vehicle autonomy system of the autonomous vehicle. The autonomous vehicle braking system can further include a secondary brake control module comprising one or more processors. The secondary brake control module can be configured to determine a failure of the primary brake control module to brake the autonomous vehicle in response to receiving the braking command. In response to determining the failure of the primary brake control module to brake the autonomous vehicle, the secondary brake control module can be configured to implement a braking action for the autonomous vehicle.
