  • Patent number: 8688328
    Abstract: When a start-up operation by a driver is detected while a vehicle is maintained at a stopped state, a target driving force for suppressing the movement of the vehicle on the road to be driven is calculated, based on the grade obtained regarding the road to be driven on. After the vehicle is driven by the target driving force, the braking force is released so as to terminate the maintaining of the stopped state of the vehicle. Preferably, the state of being driven by the target driving force is maintained until the releasing of the braking force is completed. When the releasing of the braking force is completed, the driving force is increased to start-up the vehicle. With such a start-up control, vehicles are prevented from moving temporarily in a direction opposite from the traveling direction, and a smooth star-up can be achieved.

  • Patent number: 8489305
    Abstract: When a preceding vehicle (Vb) starts during deceleration of a vehicle (Va) which is trying to stop following the stopped preceding vehicle (Vb), if the vehicle (Va) accelerates following the preceding vehicle (Vb), the driver possibly mistakes that the vehicle is equipped with an automatic start function. A virtual preceding vehicle (Vb?) is set at the stop position of the preceding vehicle (Vb), so that the vehicle (Va) is temporarily stopped following the stopping virtual preceding vehicle (Vb?) even if the actual preceding vehicle (Vb) is started. As a result, the vehicle (Va) is not started until the driver indicates the intention to start by operating a start switch, and the driver can be prevented from mistaking that the vehicle is equipped with an automatic start function.

  • Publication number: 20120324039
    Abstract: A first server including a local disk and a second server are logically partitioned by virtualization units. The first and second servers each have a storage controller LPAR with a local disk sharing function running thereon. The storage controller LPARs running on the first and second servers communicate with each other. When a disk I/O command issued by the second LPAR running on the second server is transferred to the local disk of the first server, the second LPAR reads data stored in the local disk or writes data thereto. In this way, the local disk is shared.
