Abstract:
1. A power transmitting and receiving system for a vehicle comprising: an information communication device for communicating with another vehicle by transmitting and receiving vehicle positional relation specifying information, which includes: longitudinal inter-vehicle distance specifying information for specifying a distance between the vehicle and the another vehicle in front of or behind the vehicle; and lateral displacement amount specifying information for specifying an amount of lateral displacement between the vehicle and the another vehicle; a power transmitting and receiving antenna, which has a controllable directionality, transmits wirelessly an electric power of the vehicle to the another vehicle, and receives wirelessly an electric power of the another vehicle; a directionality specifying information transmitting and receiving device for transmitting directionality specifying information for specifying a directionality of the power transmitting and receiving antenna of the vehicle to the another vehicle and for receiving directionality specifying information for specifying a directionality of a power transmitting and receiving antenna of the another vehicle; an antenna directionality controller for controlling the directionality of the power transmitting and receiving antenna of the vehicle and a directionality of the power transmitting and receiving antenna of the another vehicle based on the vehicle positional relation specifying information, the directionality specifying information of the power transmitting and receiving antenna of the vehicle, and the directionality specifying information of the power transmitting and receiving antenna of the another vehicle so that the power transmitting and receiving antenna of the vehicle faces the power transmitting and receiving antenna of the another vehicle; a light-emitting device for emitting spot light from a center of the power transmitting and receiving antenna; and a driving controller for controlling a driving condition of the vehicle and a driving condition of the another vehicle so that the spot light emitted from the light-emitting device of the vehicle coincides with the center of the power transmitting and receiving antenna of the another vehicle, or the spot light emitted from the light-emitting device of the another vehicle coincides with the center of the power transmitting and receiving antenna of the vehicle, wherein, when the driving controller confirms that the spot light emitted from the light-emitting device of the vehicle coincides with the center of the power transmitting and receiving antenna of the another vehicle, the driving controller automatically controls the driving condition of the vehicle so as to maintain a confirmed state, wherein the antenna directionality controller controls the directionality of the power transmitting and receiving antenna of the vehicle and the directionality of the power transmitting and receiving antenna of the another vehicle after the driving controller controls the spot light emitted from the vehicle to coincide with the center of the power transmitting and receiving antenna of the another vehicle, or the driving controller controls the spot light emitted from the another vehicle to coincide with the center of the power transmitting and receiving antenna of the vehicle, and wherein, when the power transmitting and receiving antenna of the vehicle does not face the power transmitting and receiving antenna of the another vehicle, directionality adjustment request information including an adjustment amount of the directionality necessary for facing the power transmitting and receiving antenna of the vehicle and the power transmitting and receiving antenna of the another vehicle mutually is transmitted to the another vehicle.
