The invention provides a working mode management method based on vehicle-mounted UWB positioning, comprising a key end, and an ECU and N UWB anchor points arranged at a vehicle end, the method comprising the following steps: S1, when a G-Sensor device of the key end detects that a key moves, a BLE of the key end is awakened and triggers broadcast pairing content; when the key is close to the vehicle end, the BLE of the ECU receives a connection request of the BLE of the key end and then carries out pairing; after the pairing is successful, the ECU is awakened; s2, the ECU collects the divided voltage of the storage battery through the ADC, and after the storage battery voltage and the key position are calculated through the ECU, the UWB anchor points are notified to be configured through the CAN network, so that the risk that the voltage of the vehicle end is further lack of power is reduced, the working state of each UWB anchor point can be dynamically adjusted according to different orientations through the orientation of the key end, the positioning precision is improved, and the service life of the vehicle end is prolonged. And the power consumption of the system is also reduced.
本发明提供了一种基于车载UWB定位的工作模式管理方法,包括钥匙端及设置于车端的ECU与N个UWB锚点,该方法包括以下步骤:S1、当钥匙端的G‑Sensor器件检测到钥匙移动后,钥匙端的BLE被唤醒并触发广播配对内容;当钥匙靠近车端,ECU的BLE收到钥匙端的BLE的连接请求后并进行配对;当配对成功后,唤醒ECU;S2、ECU通过ADC进行采集蓄电池分压的电压,通过ECU计算的蓄电池电压和钥匙位置后,再通过CAN网络分别通知各UWB锚点进行配置,实现减少车端电压进一步亏电风险,通过钥匙端的方位,可以根据不同方位动态调整每个UWB锚点的工作状态,既提高了定位精度,也降低了系统的功耗。
