The invention provides a control method of a vehicle-mounted UWB module, the module and a vehicle, and belongs to the field of UWB application. Comprising the following steps that a trigger instruction of an interrupt controller is responded, a vehicle-mounted UWB module is controlled to conduct time calibration, and the vehicle-mounted UWB module comprises a main anchor point and at least one auxiliary anchor point which are distributed on a vehicle; controlling the main anchor point to be switched between two working modes, namely a key positioning mode and a kick scanning mode according to a preset switching mode; and controlling the working mode of the auxiliary anchor point to be consistent with the working mode of the main anchor point in the process of switching the working mode of the main anchor point. The technical problem that a UWB chip in the prior art cannot multiplex a ranging function in a radar mode is solved.

    本发明提供了一种车载UWB模块的控制方法、模块及车辆,属于UWB应用领域。包括以下步骤:响应于中断控制器的触发指令,控制所述车载UWB模块进行时间校准,所述车载UWB模块包括分布在车辆上的主锚点和至少一个辅助锚点;控制所述主锚点按照预设切换方式在钥匙定位模式和脚踢扫描模式这两个工作模式之间进行切换;在所述主锚点切换所述工作模式的过程中控制所述辅助锚点的工作模式与所述主锚点的工作模式一致。本发明解决了现有技术中UWB芯片在雷达模式下无法复用测距功能的技术问题。
