Position sensing and alignment guiding test system of electric vehicle wireless charging system

Abstract

The invention relates to a position sensing and alignment guiding test system of an electric vehicle wireless charging system. The position sensing and alignment guiding test system comprises a simulation test platform and a simulation test terminal, the simulation test platform is used for simulating the movement of the electric vehicle, controlling the movement process of the simulated electric vehicle, detecting the movement state and the movement position of the simulated electric vehicle, outputting a corresponding detection signal, simulating the position sensing and alignment guiding function of the wireless charging system of the electric vehicle and outputting a corresponding sensing guiding result; and the simulation test terminal is used for generating a reference alignment path of the simulated electric vehicle and a corresponding allowable error range, detecting an error of a sensing guide result, evaluating the sensing guide result, and prompting the movement of the simulated electric vehicle based on the movement position of the simulated electric vehicle. According to the invention, the position sensing and alignment guiding functions of the wireless charging system of the electric vehicle can be conveniently and efficiently tested, and the reliability evaluation problem of the wireless charging vehicle can be solved.
