The invention discloses a backward traffic passing early warning method and device of a vehicle. The method comprises the steps: calculating the relative distance between a passing vehicle or a passing pedestrian and the vehicle after the passing vehicle or the passing pedestrian is recognized based on the passing information of the two sides of the rear part of the vehicle; and when the relative distance on any side is smaller than or equal to a first preset distance, the actual speed of the vehicle is smaller than a first preset speed and it is detected that the vehicle does not execute the braking action, controlling the vehicle to execute a first active intervention action, and parking the vehicle. According to the embodiment of the invention, the braking action of the driver is detected, and when the driver does not perform the braking action, the vehicle is actively intervened according to the distance between the passing object behind the vehicle and the vehicle and the vehicle speed, so that accidents are avoided, and the safety of the vehicle is further ensured. Therefore, the problems of continuous alarm, low intelligence, poor experience and the like when the relative distance between the obstacle and the vehicle is too small in the prior art are solved.
本申请公开了一种车辆的后向交通穿行预警方法及装置,其中,方法包括:基于车辆后方两侧的穿行信息识别到穿行车辆或穿行行人后,计算穿行车辆或穿行行人与车辆之间的相对距离;在任一侧的相对距离小于或等于第一预设距离,且车辆的实际速度小于第一预设速度,及检测到车辆未执行制动动作时,控制车辆执行第一主动干预动作,对车辆执行驻车。本申请的实施例对驾驶员的制动动作进行检测,在驾驶员无制动动作时,根据车辆后方穿行物与车辆间的距离以及车辆速度对车辆进行主动干预,避免发生事故,进一步保证车辆的安全性。由此,解决了相关技术中在障碍物与车辆间的相对距离过小时,持续报警,智能化较低,体验较差等问题。
