The invention discloses a position and foreign matter mixed detection system and an electric vehicle wireless charging control method, the system comprises a transmitting coil at a primary side and a receiving coil at a secondary side, and is characterized in that an active excitation coil is arranged above the transmitting coil, a detection coil array is arranged above the active excitation coil, and the detection coil array is arranged above the receiving coil. At least one signal line coil is further arranged on the secondary side, the active excitation coil is wound into m * n evenly-distributed grids, the directions of magnetic fields generated when current passes through the two grids on the rear adjacent side are opposite, the detection coil array comprises m * n detection coils, each detection coil correspondingly covers one grid area in the active excitation coil, and the m * n detection coils correspond to the m * n detection coils. M and n are positive integers greater than 2. The system has the advantages that the system is simple in structure and clear in logic, receiving coil position detection and metal foreign matter detection can be well achieved, and the two systems do not affect each other.

    本发明公开了一种位置和异物混合检测系统及电动汽车无线充电控制方法,系统包括原边的发射线圈和副边的接收线圈,其特征在于:在所述发射线圈上方设置有主动激励线圈,在所述主动激励线圈上方设置有检测线圈阵列,在副边还设置有至少一个信标线圈,所述主动激励线圈绕制成m*n个均匀分布的方格,电流通过后邻边的两个方格中产生的磁场方向相反,所述检测线圈阵列包括m*n个检测线圈,每一个检测线圈对应覆盖所述主动激励线圈中的一个方格区域,m和n为大于2的正整数。其效果是:系统结构简洁、逻辑清楚,能够较好的实现接收线圈位置检测和金属异物检测,且两系统间互不影响。
