  • Patent number: 10811973
    Abstract: When a calculated duty obtained through a feedback operation is within a specific range, a duty outside the specific range is adopted without increasing a difference from the operation result. When a calculated duty obtained through a feedback operation is within a modification target range, an arithmetic unit of a DC-DC converter selects a predetermined value as a substitute and determines a usage duty based on the substitute. Whenever the calculated duty within the modification target range is obtained, the arithmetic unit updates a cumulative value by accumulating a value indicating a difference between the usage duty based on the substitute and the calculated duty. When a predetermined condition is met, the arithmetic unit modifies the usage duty by performing addition or subtraction on a part or whole of the cumulative value, and updates the cumulative value by subtracting the value used for modifying the usage duty.

  • Patent number: 10807546
    Abstract: The present invention pertains to a vehicular circuit body composed mainly a backbone trunk line portion provided in a vehicle and a plurality of backbone control boxes. An electrical connection path is realized with a structure which is simplified like a spine by connecting branch line sub-harnesses to backbone control boxes. An electrical connection between an engine room and a vehicle interior is performed by arranging a main power source cable and a part of a branch line sub-harness so as to penetrate a dash panel. Thus, it is possible to easily arrange the vehicular circuit body without reducing sealing performance of a portion penetrating the dash panel.

  • Patent number: 10800271
    Abstract: A supply device for a motor vehicle has a DC/DC converter and a control device for the DC/DC converter. The DC/DC converter has first terminals and second terminals, which first terminals are configured for electrical connection to a first energy storage or a first energy source and which second terminals are configured for electrical connection to a second energy storage or a load. The DC/DC converter is configured, in a first state to enable a conversion of a first DC voltage at the first terminals into a lower second DC voltage at the second terminals and, in a second state, to carry out no conversion of a first DC voltage at the first terminals into a lower second DC voltage at the second terminals. The control device enables an energy supply at the second terminals by repeatedly changing the DC/DC converter between the first state and the second state.
