Abstract
Braking systems and methods for an autonomous vehicle are provided. Braking devices are associated with respective wheels of the autonomous vehicle. A hydraulic circuit is connected between a primary braking module (PBM) and the braking devices and connected between a secondary braking module (SBM) and the braking devices. One of a PBM electronic control unit and a SBM electronic control unit is configured to: in response to detecting a communications failure of the other braking module, apply a predetermined hydraulic pressure operation in the hydraulic circuit. The other of the PBM electronic control unit and the SBM electronic control unit is configured to identify, based on output from the at least one sensor, the predetermined hydraulic pressure operation being applied by the one of the PBM electronic control unit and the SBM electronic control unit, and select and execute a braking profile based thereon.
