  • Publication number: 20120053808
    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: 20120046844
    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.

  • Publication number: 20120030504
    Abstract: [Object] To increase the speed of copy processing from an online computer 101 to a standby computer 102. [Solution] When copying copy target information from the online computer 101 to the standby computer 102, a status copy processing unit 110: recognizes, as a synchronous point, a point in time when execution of a first application (AP #1), from among applications 108, is completed; extracts only information stored in a use area 401 of an OS 106 and a use area 403 of a second application (AP #2) from a storage area 400 of a memory at this synchronous point; and transfers the extracted information, as the copy target information necessary to continue the processing, from the online computer 101 to the standby computer 102.
