Systems and Methods for Brake Redundancy for an Autonomous Vehicle

A method for braking an autonomous vehicle, comprising:

• receiving, by one or more processors of a secondary brake control module, a braking command for a primary brake control module of the autonomous vehicle;
• determining, by the one or more processors, a failure of the primary brake control module based at least in part on the braking command;
• and
• in response to determining the failure of the primary brake control module, implementing, by the one or more processors, a braking action to brake the autonomous vehicle.

An autonomous vehicle, comprising:

• a vehicle autonomy system comprising one or more processors, the vehicle autonomy system configured to generate a braking command for the autonomous vehicle;
• and
• a braking system, comprising:
• a primary brake control module comprising one or more processors, the primary brake control module configured to receive the braking command generated by the vehicle autonomy system, and in response to receiving the braking command, brake the autonomous vehicle;
• and
• a secondary brake control module comprising one or more processors, wherein the secondary brake control module is configured to:
• determine a failure of the primary brake control module to brake the autonomous vehicle in response to the braking command;
• and
• in response to determining the failure of the primary brake control module to brake the autonomous vehicle, implement a braking action for the autonomous vehicle.
