Autonomous coil alignment system for dynamic wireless charging electric vehicle

摘要

The present invention relates to an autonomous coil alignment system for an electric vehicle in a dynamic wireless charging method. The autonomous coil alignment system comprises: a single sensor coil wound around a central portion of a front portion or a rear portion of a load coil; a side position detection unit receiving an output voltage of the sensor coil and detecting a position of the load coil in a side direction with respect to a source coil; and a steering controller receiving the position in the side direction detected by the side position detection unit and outputting a steering command. Therefore, the autonomous coil alignment system can easily implement side alignment between coils.
