US 12,015,284 B2 · Low frequency sensor based apparatus and method for measuring vehicle position

Abstract

A method for measuring a position, is performed by a vehicle assembly (VA) for alignment between a ground assembly (GA) and the VA. The method includes transmitting low frequency (LF) signals to initiate alignment with the GA and estimating a position of a vehicle using at least one sensor mounted on the vehicle. Information regarding the estimated position of the vehicle is provided to the GA and information regarding a position of the vehicle measured by LF receive antennas of the GA and an acceleration flag calculated by the GA is received. Accordingly, a transmission strength of the LF signals transmitted by the VA is adjusted based on the information regarding the position of the vehicle measured by the LF receive antennas and the acceleration flag.

Dependent claims

A method for measuring a position, performed by a ground assembly (GA) for alignment between the GA and a vehicle assembly (VA), the method comprising:

detecting, by a controller, low frequency (LF) signals transmitted by the VA through LF receive antennas of the GA;
calculating, by the controller, a position of a vehicle based on the LF signals;
receiving, by the controller, information regarding a position of the vehicle estimated by the VA;
calculating, by the controller, an acceleration flag by comparing the position of the vehicle calculated based on the LF signals with the position of the vehicle estimated by the VA;
and
transmitting, by the controller, information regarding the position of the vehicle calculated based on the LF signals and the acceleration flag to the VA.
