A method for operating a diagnostic system of a vehicle including a fail operational power system (FOPS) module and a fail operational system (FOS) module includes the FOS module requesting a microcontroller of the FOPS module to generate a diagnostic control signal. The FOS module receives the diagnostic information from a component module of the FOPS module based on the diagnostic control signal generated by the microcontroller. The FOS module executes isolator diagnostics based on the received diagnostic information.

Systems and processes are provided for configuring sensory devices within a vehicle. In general, a system includes a computer readable storage medium that stores at least one configuration instruction. The system further includes a microprocessor configured to generate a message based on the at least one configuration instruction. The system further includes a routing device configured to communicate the message to a sensory device of the vehicle according to a virtual identifier associated with a local area network routing configuration.

Method for operating a fail operational power system for a vehicle includes monitoring voltages on first and second power distribution paths arranged in parallel. Each path includes a respective first or second isolator switch effective when operative in a closed state to power the respective path by a respective energy storage device for supplying electrical power to one or more loads partitioned on each of the paths. A third isolator switch controllably operative between open and closed states is monitored. The closed state of the third isolator switch connects the paths and the open state opens the connection between the paths. When a predetermined operating mode requiring fail operational power is enabled, the third isolator switch is controlled to the open state when at least one of the monitored voltages violates a reference voltage and is controlled to the closed state when neither one of the monitored voltages violate the reference voltage.

A resettable circuit protection system for a vehicle includes a power outlet, a resettable circuit protection device, a resettable switch, a control module, and a user interface. The resettable circuit protection device is disposed in power communication with the power outlet, is operable between open and closed positions, and is configured to automatically open in response to an electrical overload condition at the power outlet. The resettable switch is electrically disposed in series with the circuit protection device, and operates between open and closed positions. The control module is disposed in signal communication with the circuit protection device and the switch. The user interface is disposed in signal communication with the control module. When the circuit protection device is open, the control module is responsive to facilitate display of a message at the user interface indicative of the circuit protection device being open, and to facilitate opening of the switch.

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.

Methods, systems are provided for controlling an auxiliary power outlet in a vehicle. The method includes connecting the battery powered device to the accessory power outlet, synchronizing communications between the battery powered device to a computing device of the vehicle, and determining when the battery powered device is connected to an electric bus and is charging. When the battery powered device is either not connected to the electric bus or the battery powered device is not charging, then disconnecting power from the accessory power outlet. The system includes a battery, an electrical bus electrically connected to the battery, at least one auxiliary power outlet in electrical communication with the battery and configured to mate with a battery charging port of a battery operated device; and an electronic control unit (ECU). The ECU is configured to disconnect power from the accessory power outlet when the battery is charged.

A motor vehicle has a plurality of doors, each secured by a lock, peripheral control units, each connected to one of said locks, for sending a command signal to an actuator of the lock, a central control unit for sending command signals to the actuators of the locks, and an accident detector. If the accident detector has detected an accident, at least one of the actuators is switchable from a central operating mode in which it executes command signals of the central control unit and its associated peripheral control unit into a peripheral operating mode in which it executes only command signals from its peripheral control unit.
