  • Publication number: 20230166678
    Abstract: As the level of autonomous driving of an automobile is improved, traveling in a system without a driver is required, and high reliability of the system is essential. One method for achieving high reliability is redundancy of a power supply. To construct a redundant power supply network, a redundant power supply network is required in addition to a main power supply network, and the number of wires of the network increases. In addition, since a cable having a thick core wire is used as a power supply wiring in order to handle a large current, the weight of the cable becomes heavy, which leads to fuel consumption degradation of the vehicle. An electronic control device 11-B receives power fed from a power storage unit 12-A via another electronic control device 11-A, as a redundant power supply redundant to a power superimposition data wiring 16.
