The described techniques relate to coordinating and managing faults of systems of a vehicle, such as an autonomous vehicle, to enable the vehicle to respond safely and appropriately to the faults. In examples, a centralized fault monitor system receives faults from different vehicle systems, maps the received faults to associated fault constraints, prioritizes different and shared parameters between the fault constraints, and communicates the constraint parameters to appropriate vehicle systems accordingly.

Fault coordination and management

A vehicle can include a battery architecture configured to provide electrical power to motors, accessories, and other components of the vehicle. The architecture can include a controller coupled to multiple battery units. Each battery unit can include a battery and a battery management system. Additionally, each battery unit can be coupled to a controller and to other battery units. Through the use of redundant coupling and redundant data transmitted to and from the controller, battery units, and other components, the architecture can detect a fault and continue to operate while providing an indication of the fault.
