The invention discloses a method for preventing vehicle door collision. The method comprises the following steps: when a vehicle is static, calculating the Doppler frequency shift amount of a UWB signal and/or the radial speed of an object relative to a UWB signal transceiving module according to the UWB signal transmitted by a vehicle-mounted UWB signal transceiving module and the UWB signal reflected by the object around the vehicle and received by the UWB signal transceiving module; if the Doppler frequency shift amount is greater than a set frequency shift amount threshold value or the radial speed is greater than a set speed threshold value, calculating the position of the object; and judging whether the time when the object reaches the vehicle door is smaller than a set time threshold value or not according to the radial speed and position of the object, if yes, locking the vehicle door to prevent the vehicle door from being opened; otherwise unlocking the vehicle door to allow the vehicle door to be opened. According to the method, the vehicle door collision can be prevented only by supporting the UWB technology by the vehicle, so that a solution for preventing the vehicle door collision can be provided for most common vehicle types with lower cost.
本发明公开了一种用于防止车门碰撞的方法，包括：在车辆静止时，根据由车载的UWB信号收发模块发送的UWB信号和由UWB信号收发模块接收到的被车辆周围的物体反射的UWB信号计算UWB信号的多普勒频移量和/或物体相对于UWB信号收发模块的径向速度；如果多普勒频移量大于设定的频移量阈值或者径向速度大于设定的速度阈值，计算物体的位置；根据物体的径向速度和位置判断物体到达车门的时间是否小于设定的时间阈值，如果判断结果为是，则锁定车门以防止车门被打开，如果判断结果为否，则将车门解锁以允许车门被打开。本发明中，仅需要车辆支持UWB技术就可以防止车门碰撞，从而能够以较低的成本为大多数普通车型提供防止车门碰撞的解决方案。
