Abstract:
Based on a vehicle speed Vv, a vehicle moving amount cvp is calculated from cvp=∫Vv·dt. From the Pythagorean theorem, expressions y 2 +x 2 =ra 2  and y 2 +(cb−x) 2 =cvp 2  are held. From these two expressions, an ECU of a non-contact power transmission system obtains x and y. In the expressions, y is a distance in a horizontal direction from a power transmission coil, x is a distance in a vertical direction from the power transmission coil, and ra is a distance from the power transmission coil at a two-dimensional current position and is obtained in advance from a correspondence relation between the distance and the intensity of a power transmitted from the power transmission coil.

Claim (Index 1):
A non-contact power transmission system comprising a charging station including a power transmission unit configured to transmit a certain transmission power in a radial direction, and a vehicle including a power reception unit configured to receive a power in accordance with the transmission power without contact, a control unit of the vehicle comprising:\n a voltage value detection unit configured to detect a voltage value of a reception power received by the power reception unit; a storage unit configured to store in advance a voltage value characteristic of a region where, when the power transmission unit is regarded as a coordinate origin and a distance in a radial direction from the coordinate origin is ra, the voltage value is unique relative to the distance ra; and a moving amount detection unit configured to detect a moving amount of the vehicle, wherein: a position where a predetermined voltage value is detected by the voltage value detection unit of the vehicle in the region where the voltage value is unique, is set as a detection start position; when a distance from the detection start position to the coordinate origin is cb, a vehicle speed is Vv, and the moving amount from the detection start position is cvp, the moving amount cvp at a current position is obtained by cvp=\u222bVv\u00b7dt; the distance ra from the coordinate origin is obtained with reference to the voltage value characteristic by a voltage detected by the voltage value detection unit at the current position; and when a distance on a vertical axis is x and a distance on a horizontal axis is y in orthogonal two axes of the distance ra in the radial direction with respect to the coordinate origin and the distance cb from the detection start position to the coordinate origin is on the vertical axis, the distance x and the distance y at the current position from the coordinate origin are obtained respectively from\n x= ( ra 2 \u2212cvp 2 +cb 2 )/2 \u00b7cb  \n y={ ( ra+cb+cvp )( ra\u2212cb+cvp )( ra+cb\u2212cvp )(\u2212 ra+cb+cvp )} 1/2 /2\u00b7 cb.
