Abstract: A ground power supply apparatus for transmitting power to a vehicle by noncontact has: a plurality of power transmission apparatuses for transmitting power to the vehicle; at least one detection device for detecting a signal emitted from the vehicle using narrow range wireless communication; and a controller for controlling the power transmission apparatuses. The power transmission apparatuses are arranged in a road aligned in a direction of advance of the vehicle. One first detection device is arranged so as to enable detection of the signal at an upstream side from the most upstream power transmission apparatus. The control device controls transmission of power from power transmission apparatuses other than the first power transmission apparatus positioned the most upstream, based on the signal detected by the first detection device and power transmission result information at the power transmission apparatus positioned upstream of that power transmission apparatus.

Abstract: An information processing apparatus accepts an inquiry about rental of a power feed mat that can supply electric power to a movable body. The power feed mat includes a substrate including a power transmission coil and a functional body that performs at least one function of a plurality of functions. The inquiry includes an instruction to designate the at least one function of the plurality of functions. In the information processing apparatus, association information in which function information is associated with identification information of each of a plurality of power feed mats is stored. The function information indicates which of the plurality of functions the power feed mat performs. The information processing apparatus specifies at least one power feed mat among the plurality of power feed mats based on the accepted inquiry and the association information and provides information based on a result of specifying.

Abstract: A power feed system includes a power feed mat and a computer. The power feed mat includes a plurality of power transmission coils. The power feed mat is configured to feed power to at least one movable body on the power feed mat by using at least one of the plurality of power transmission coils. The computer is configured to determine whether or not to permit power feed to a movable body that requests power feed. In the power feed system, when the computer determines not to permit power feed, the power feed mat does not feed power to the movable body that requests power feed.

Abstract: An abnormality judgment apparatus provided with a processing part, a communicating part able to communicate with a mobile object provided with a power reception apparatus receiving power wirelessly transmitted from a power transmission apparatus installed on a road, and a storage part storing power reception history information received from the mobile object. The processing part calculates a probability of occurrence of an abnormality in the power reception apparatus of the mobile object based on the power reception history information and detects a presence of an abnormality occurring location where the power transfer efficiency becomes less than a predetermined value and judges that an abnormality has occurred in the power transmission apparatus installed at the abnormality occurring location when an abnormality occurring location is detected and the probability becomes less than a predetermined judgment threshold value.

Abstract: A control system for a hybrid vehicle with an internal combustion engine and an electric motor includes a zone in which the hybrid vehicle can move is divided in advance into a restriction zone in which the operation of the internal combustion engine should be restricted, and an allowable zone in which the operation of the internal combustion engine is permitted. A new route is computed if an SOC of a battery of the hybrid vehicle is lower than a predetermined threshold value while the hybrid vehicle is located within the restriction zone when the hybrid vehicle moves along a computed route, or if the SOC is predicted to be lower than the threshold value while the hybrid vehicle is located within the restriction zone when the hybrid vehicle is assumed to move along the computed route.

Abstract: Provided is a hybrid vehicle that includes an internal combustion engine and an electric motor, and switches a driving mode between an EV mode and an HV mode. A position of the hybrid vehicle is determined, when determination is made that the hybrid vehicle is within a low emission zone where operation of the internal combustion engine is to be restricted, the operation of the internal combustion engine is stopped, and when determination is made that the hybrid vehicle is within an entrance area adjacent to a boundary of the low emission zone outside the low emission zone, an occupant of the hybrid vehicle is notified that the hybrid vehicle enters or is likely to enter the low emission zone soon.
