first embodiment

[0146]FIG. 9 is a flowchart for illustrating the control performed in the vehicle and the electric power transmission device in the first embodiment of the invention.

[0147]Referring to FIG. 6 and FIG. 9, in the vehicle 100, in step S10, the vehicle ECU 300 monitors whether or not there is a request for charging. If it is determined that the charging start signal TRG has been input through an operation by a user or the like, the vehicle ECU 300 transmits to the electric power transmission device 200 a message indicating that there is a request for charging, via the communication portion 160. Then, the processing proceeds from step S10 to step S20.

[0148]On the other hand, in the electric power transmission device 200, in step S110, the electric power transmission ECU 240 monitors whether or not there is a request for charging. If a message indicating that a request for charging has been made is transmitted from the communication portion 160 of the vehicle 100 and the electric power tr...

second embodiment

[0174]In the second embodiment of the invention, an example in the case where an electric power transmission device is provided with a plurality of electric power transmission units or a movable electric power transmission unit will be described. In the second embodiment of the invention, a processing of selecting or moving an electric power transmission coil is performed as indicated by steps S132 and S134, in addition to the processing described with reference to FIG. 9 of the first embodiment of the invention.

[0175]FIG. 14 is a flowchart for illustrating the control performed in the vehicle and the electric power transmission device in the second embodiment of the invention.

[0176]Referring to FIG. 6 and FIG. 14, in the vehicle 100, in step S10, the vehicle ECU 300 monitors whether or not there is a request for charging. If it is detected that the charging start signal TRG has been input due to an operation by the user or the like, the vehicle ECU 300 transmits to the electric pow...

third embodiment

[0196]FIG. 17 is a flowchart for illustrating the control performed in the vehicle and the electric power transmission device in the third embodiment of the invention.

[0197]Referring to FIG. 6 and FIG. 17, in the vehicle 100, in step S210, the vehicle ECU 300 monitors whether or not there is a request for charging. If it is detected that the charging start signal TRG has been input through an operation by the user or the like, the vehicle ECU 300 transmits to the electric power transmission device 200 a message indicating that there is a request for charging, via the communication portion 160. Then, the processing proceeds from step S210 to step S220.

[0198]On the other hand, in the electric power transmission device 200, in step S310, the electric power transmission ECU 240 monitors whether or not there is a request for charging. If the message indicating that a request for charging has been made is transmitted from the communication portion 160 of the vehicle 100 and the electric p...

Abstract

An electric power reception device for a vehicle is equipped with an electric power reception unit that is configured to be able to receive electric power from an electric power transmission device in a non-contact manner, a communication portion that transmits information on a position or dimension of the electric power reception unit to the electric power transmission device, and a vehicle ECU that controls the communication portion. Preferably, the vehicle ECU transmits pre-stored information to the electric power transmission device with the aid of the communication portion, before allowing a vehicle to be parked at an electric power reception position of the electric power transmission device. The information includes at least one of a size of the electric power reception unit, a size of the vehicle in which the electric power reception unit is mounted, and a mounting position of the electric power reception unit in the vehicle.

Description

TECHNICAL FIELD[0001]This invention relates to an electric power reception device for a vehicle, an electric power transmission device, and a non-contact electric power transmission / reception system.BACKGROUND ART[0002]In recent years, electric vehicles and hybrid vehicles, which run by using electric energy instead of fuel or in addition to fuel with a view to reducing the amount of carbon dioxide discharged from the vehicles for the purpose of preventing global warming, have been attracting attention. Moreover, there have also been plug-in hybrid vehicles that are configured such that their batteries, which are also mounted in hybrid vehicles, can be charged with electric energy from outside the vehicles.[0003]Furthermore, with a view to achieving an improvement in user-friendliness, technologies of feeding electric power in a non-contact manner have been reviewed as a method of feeding electric energy to a vehicle from outside the vehicle. In feeding electric power in a non-conta...
