  • Patent number: 10503577
    Abstract: As a type of an event that occurs in a computer system, an event type for which display of performance data is to be requested in the future is defined in advance. A management system, upon detection of occurrence of an event that belongs to the event type for which it is defined that display of performance data is to be requested in the future, selects, as a read-ahead target, at least one of an event component which is a component in which the detected event has occurred, and a relevant component which is a component directly or indirectly coupled to the event component. When the performance data of the selected component is not stored in a memory, the management system reads the performance data of the selected component from a performance store to the memory.

The electronic control unit is configured to select a second acceleration lower than the first acceleration as the final target acceleration when a vehicle speed of the passing lane preceding vehicle is equal to or lower than that of the host vehicle. The actuator is configured to control the host vehicle such that an actual acceleration of the host vehicle approaches the final target acceleration.

  • Publication number: 20190126862
    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.
