  • Patent number: 9910096
    Abstract: A control apparatus includes: a tentative target calculator that calculates a tentative target value for a first physical quantity, based on a control target value; a correction calculator that calculates a correction value; and a first target value calculator that calculates as a first target value by adding the correction value to the tentative target value. When a second sensor fails, the first target value calculator designates the tentative target value as the first target value without adding the correction value to the tentative target value. The control apparatus further includes a variation inhibitor that inhibits the designated first target value from greatly varying due to the failure in the second sensor.

    Abstract: A method of adjusting a transmission probability for device-to-device out-of-network discovery may include receiving, outside of network coverage, device-to-device discovery messages associated with a discovery resource pool. A count of idle resources, a count of resources associated with successfully received discovery messages, and a count of resources associated with discovery messages not successfully received may be detected for the discovery resource pool. A transmission probability associated with the discovery resource pool may be adjusted based at least in part on one or more of the count of idle resources, the count of resources associated with successfully received discovery messages, and the count of resources associated with discovery messages not successfully received. A device-to-device discovery message may be transmitted via the discovery resource pool based at least in part on the transmission probability.

  • Publication number: 20180032920
    Abstract: A vehicle management system for handling vehicle reservations of a vehicle-sharing service includes a reservation request input device, a reservation result transmitter, and a reservation processor. When a new vehicle reservation request is input to the reservation request input device, the reservation processor performs a simple process for a vehicle allocation which allocates a vehicle to the new vehicle reservation request, and the result transmitter transmits a reservation result to a user. When the time duration after the performance of the simple process and before the rental start time for the new vehicle reservation is equal to or greater than a threshold value, the reservation processor performs an optimization process to update the vehicle allocation for the new vehicle reservation request, quickly presenting a reservation result to the user while reducing an operation cost of the vehicle-sharing service.
