摘要： An in-vehicle device includes a first controller and a second controller. The first controller includes at least one physical core for executing a first unit related to control of hardware and a second unit related to provision of a service. The second controller starts the first controller in response to occurrence of a start trigger. The first controller starts the first unit, and then starts the second unit when the first controller is started by the second controller. The first unit and the second unit are restarted when an abnormality of the first unit is detected by the second controller or an abnormality of the second unit is detected by the first unit. The first unit, the second unit and the second controller are restarted when an abnormality of the second controller is detected by the second controller.

摘要： An electrical power distribution system includes a first power bus operating in a first voltage range and a second power bus operating in the first voltage range. A first eFuse circuit selectively couples a power source to the first power bus. A second eFuse circuit selectively couples the power source to the second power bus. A first accumulator is coupled to a first node between the first eFuse circuit and the first power bus. A second accumulator is electrically coupled to a second node between the second eFuse circuit and the second power bus. The first eFuse circuit opens in response to a first electrical fault at the first power bus, and the second power bus is powered with the power source or the first accumulator. The second eFuse circuit opens in response to a second electrical fault at the second power bus, and the first power bus is powered with the power source or the first accumulator.
