Title:
NON-CONTACT POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/180973
Kind Code:
A1
Abstract:
Provided is a non-contact power transmission system (10) with which it is possible to individually detect the position of a receiving unit with respect to a transmission unit, even if there are positions at which the same microvoltage values are indicated, even if the distance differs, due to the shape of the transmission coil (11) of the transmission unit and the receiving coil (12) of the receiving unit. At a position at which the position differential value of the detected microvoltage exceeds a zero value, said position is set to the initial position (+xint) of the movement displacement of the vehicle, and the movement displacement (cvp) on the basis of vehicle velocity (Vv) is calculated to a position (+xc) at which the microvoltage value characteristics (2020s) can be used from said initial position to (+xc to 0). From the position (+xc) at which the microvoltage characteristics (2020s) can be used to the center position of the transmission coil (11), the movement displacement (distance (x)) to the maximum peak value (vlpemax) is calculated by referring to the microvoltage characteristics (2020s) with the detected microvoltage value (vlpe) as an argument.
