  • Fail operational power system with single energy storage
    Patent number: 9184582
    Abstract: Method for operating a fail operational power system for a vehicle includes monitoring a first voltage on a first power distribution path and a second voltage on a second power distribution path. An isolator switch controllably operative between open and closed states is monitored. The closed state connects the first and second power distribution paths and the open state opens the connection between the first and second power distribution paths. Each of the monitored first and second voltages is compared to a reference voltage. When a predetermined operating mode requiring fail operational power is enabled, the isolator switch is controlled to the open state when at least one of the monitored first and second voltages violates the reference voltage and the isolator switch is controlled to the closed state when neither one of the monitored first and second voltages violates the reference voltage.
