The invention discloses a wireless charging alignment guiding method and equipment. The method comprises the following steps: judging whether to enter coarse guiding or fine guiding, wherein the coarse guiding comprises the following steps: acquiring first geomagnetic data of a vehicle; s22, acquiring a GPS, judging whether there is a stored geomagnetic database, if yes, entering S231, otherwise, entering S232; s231, comparing and matching the first geomagnetic data with a stored geomagnetic database; s232, comparing and matching the first geomagnetic data with a geomagnetic database obtained from a ground end; the fine guiding comprises the steps: S31, receiving the positioning electromagnetic signal; s32, comparing and matching the positioning electromagnetic signal with an electromagnetic database, judging whether the positioning electromagnetic signal is credible or not, and if so, entering S33 to complete a guiding action at least according to the positioning electromagnetic signal; otherwise, performing a coarse guiding step at the same time until the positioning electromagnetic signal is credible. Environmental interference is reduced, coarse guidance and fine guidance are achieved, and alignment operation of wireless charging is completed reasonably and efficiently. Meanwhile, whether a geomagnetic database needing to be stored exists or not is judged in cooperation with GPS information, and the guiding efficiency is improved.

    本发明公开了无线充电对准引导方法和设备,方法包括判断进入粗引导或细引导;粗引导为:获取车辆所在处的第一地磁数据;S22获取GPS,判断是否有存储的地磁数据库,是则S231否则S232;S231第一地磁数据与存储的地磁数据库对比和匹配;S232将第一地磁数据与从地面端获取的地磁数据库对比和匹配;细引导为S31接收所述定位电磁信号;S32将定位电磁信号与电磁数据库对比和匹配,判断所述定位电磁信号是否可信,是则进入S33至少根据所述定位电磁信号完成引导动作;否则同时进行粗引导步骤,直至定位电磁信号可信。减少环境的干扰,具有粗引导和细引导,合理高效的完成无线充电的对准作业。同时配合GPS信息判断是否有应存储的地磁数据库,提高引导效率。
