Abstract
An autonomous vehicle can include multiple low voltage power domains. Each low voltage power domain can comprise a low voltage power distribution unit (LVPDU). An LVPDU can include a failsafe switch that can selectively couple or de-couple the low voltage power domain from a shared backup low voltage power source, which can be configured to concurrently supply backup power multiple low voltage power domains or LVPDUs. A first LVPDU of a first low voltage power domain can generate a control signal to control the failsafe switch of a second LVPDU of the second low voltage power domain to disconnect the second low voltage power domain from the shared low voltage backup power source, and vice versa.
