Abstract: A controller is a control device for a vehicle including an engine, an automatic transmission, and an oil pump and executes a sailing stop control that stops the engine and brings the automatic transmission into a neutral state when a sailing stop condition is satisfied. The controller cancels the sailing stop control to start the engine when a road inclination becomes larger than a predetermined value during the sailing stop control.

Abstract: An apparatus includes a cache memory for storing user data and control information of the apparatus, a nonvolatile memory and a processor for executing a process including when the power failure occurs, saving the user data and the control information stored in the cache memory into the nonvolatile memory, when the power failure recovers, restoring the data stored in the nonvolatile memory into the cache memory, and erasing the data stored in the nonvolatile memory after restoring the data into the cache memory and when another power failure occurs during erasing the data stored in the nonvolatile memory, erasing the control information stored in the nonvolatile memory if the control information is remained in the nonvolatile memory and saving, into the nonvolatile memory, the updated control information stored in the cache memory and the user data which has been erased from the nonvolatile memory.

Abstract: A storage system in which a plurality of storage device enclosures having duplicated device controllers are connected through cable connections, the storage system includes a device controller information management section that manages a state of a corresponding device controller in a storage device enclosure as device controller information, and an management section that manages the plurality of storage device enclosures, the overall management section includes an improper connection determination section that determines whether an improper connection in a cable connection between device controllers in the different storage device enclosures exists or not based on a connection state of the device controller according to a connection order of the cables, and based on the device controller information acquired from the device controller information management section corresponding to each of the device controllers.
