The invention provides an early warning method and device for vehicle curve collision avoidance, and the method comprises the steps: obtaining a first distance between a first vehicle and relay equipment, and a second distance between the second vehicle and the relay equipment under the condition that the first vehicle and the second vehicle are in a visual range, the third distance between the first vehicle and the second vehicle is determined, and the first vehicle and the second vehicle run in opposite directions; calculating the sum of the first distance and the second distance to obtain a first ranging distance between the first vehicle and the second vehicle; selecting a minimum value from the third distance and the first distance measurement distance to obtain a target distance measurement distance; and if the target distance measurement distance is smaller than a preset distance threshold value, carrying out anti-collision early warning. According to the invention, by introducing the relay device, the problem that two UWB devices cannot measure the distance or may obtain the wrong distance through reflection in the prior art can be solved, and the effect of improving the accuracy of anti-collision early warning is achieved.

    本申请提供了一种车辆弯道防撞的预警方法及装置,其中,该方法包括:在第一车辆与第二车辆处于可视范围的条件下,获取第一车辆与中继设备之间的第一距离、第二车辆与中继设备之间的第二距离,以及第一车辆与第二车辆之间的第三距离,第一车辆与第二车辆相向行驶;计算第一距离与第二距离之和,得到第一车辆与第二车辆之间的第一测距距离;从第三距离和第一测距距离中选取最小值,得到目标测距距离;若目标测距距离小于预设距离阈值,则进行防撞预警。本申请通过引入中继设备能够解决现有技术中存在的两个UWB设备无法测距或可能通过反射得到错误距离的问题,达到提高防撞预警准确性的效果。
