    Abstract: In one embodiment, a system determines a signal fault at a communication bus of an autonomous driving vehicle (ADV). In response to determining the signal fault, the system sends a brake pre-charge command to a brake system of the ADV to pre-charge a brake of the ADV. The system determines a preset tolerance time to validate the signal fault. In response to a time elapse of the preset tolerance time, the system validates the signal fault at the communication bus or determine a signal fault at another communication bus. In response to validating the signal fault at the communication bus or determining the signal fault at the another communication bus, the system sends a brake command to the brake system of the ADV to engage brakes for the ADV.

    Abstract: A braking system conducts an electronic command signal via a cable extending through multiple first vehicles in a first segment of a multi-vehicle system. The electronic command signal directs engagement or release of an air brake coupled to a brake pipe that extends along a length of the multi-vehicle system. A pneumatic command signal is communicated via the brake pipe to one or more second vehicles in a second segment of the multi-vehicle system. The pneumatic command signal directs one or more of the engagement or the release of the air brake coupled to the brake pipe in the one or more second vehicles.
