The invention relates to a key positioning method, a key positioning device and a vehicle. The key positioning method comprises the following steps: respectively determining the coordinates of each positioner and the projection distance between every two projections according to the arrangement positions of the three positioners in the vehicle; determining the test distance between the positioner and the key according to the distance measuring signal transmitted between each positioner and the key; calculating a key height coordinate of the key relative to the base plane at least according to each projection distance and each test distance; and calculating a key projection coordinate of the key on the base plane at least according to the positioner projection coordinate of each positioner, each test distance and the key height coordinate, and generating a key coordinate of the key according to the key projection coordinate and the key height coordinate.

    本公开涉及一种钥匙定位方法、钥匙定位装置和车辆。该钥匙定位方法包括:根据所述三个定位器在所述车辆中的布置位置,分别确定每个定位器的定位器坐标以及每两个投影之间的投影距离;分别根据在每个定位器与钥匙之间传输的测距信号,确定该定位器与所述钥匙之间的测试距离;至少根据每个投影距离和每个测试距离,计算所述钥匙相对所述基面的钥匙高度坐标;以及至少根据每个定位器的定位器投影坐标、每个测试距离和所述钥匙高度坐标,计算所述钥匙在所述基面上的钥匙投影坐标,并根据所述钥匙投影坐标和所述钥匙高度坐标产生所述钥匙的钥匙坐标。
