The invention provides a coil alignment method and system for wireless charging and a wireless charging transmitting device. The method is suitable for a movable wireless charging transmitting device,and the method comprises the steps: obtaining vehicle parking information of a to-be-charged vehicle and an installation position of a wireless charging receiving coil relative to a wheel; moving thewireless charging transmitting device to the to-be-charged vehicle and allowing the device to enter the bottom of the to-be-charged vehicle along the direction mark of the parking space of the to-be-charged vehicle; measuring the relative distances between the wireless charging transmitting device and two wheels of the to-be-charged vehicle through a distance measuring module; and controlling a transmitting coil of the wireless charging transmitting device to be aligned with the wireless charging receiving coil in combination with the mounting position of the wireless charging receiving coilrelative to the wheel and the vehicle parking information. By adopting the movable wireless charging transmitting device, automatic alignment of the transmitting coil and the receiving coil in wireless charging is realized, the coil alignment precision is improved, and the wireless charging efficiency is improved.

    本发明提供了一种无线充电的线圈对准方法、系统及无线充电发射装置,所述方法适用于可移动的无线充电发射装置,所述方法获取待充电车辆的车辆停放信息和无线充电接收线圈相对车轮的安装位置;所述无线充电发射装置移动至所述待充电车辆,并沿着所述待充电车辆的停放车位的方向标记进入所述待充电车辆车底;通过所述测距模块测量所述无线充电发射装置分别与所述待充电车辆的两个车轮间的相对位置,并结合无线充电接收线圈相对车轮的安装位置以及所述车辆停放信息,控制所述无线充电发射装置的发射线圈与所述无线充电接收线圈对准。采用可移动的无线充电发射装置实现无线充电中发射线圈和接收线圈的自动对准,提高线圈对准精度,无线充电效率提升。
