The invention relates to the technical field of automobile control, and provides a control method and device for preventing lateral collision of rearview mirrors and an automobile. The method comprises the steps that when it is detected that an obstacle exists around a vehicle, the driving track of the vehicle is obtained; according to the type of the driving track, the time urgency degree of the rearview mirror approaching an obstacle in the first direction is determined, the first direction is the vehicle driving direction, the transverse distance between the rearview mirror and the obstacle in the second direction is calculated in real time, the second direction is perpendicular to the first direction, and under the condition that the transverse distance is smaller than or equal to a preset first threshold value, the rearview mirror approaches the obstacle. Whether the time urgency degree of the rearview mirror approaching the obstacle in the first direction is smaller than or equal to a preset second threshold value or not is judged; if yes, the corresponding rearview mirror is controlled to be folded. The rearview mirror is intelligently controlled to be folded according to the obstacle condition, the dependence on subjective judgment of a driver and driving experience is reduced, and the probability of transverse collision of the rearview mirror is effectively reduced.
本申请涉及汽车控制技术领域,提供了一种防止后视镜发生横向碰撞的控制方法、装置和汽车。该方法包括:当检测到车辆周围有障碍物时,获取车辆的行驶轨迹;根据行驶轨迹的类型,确定后视镜在第一方向上接近障碍物的时间紧迫度,第一方向为车辆行驶方向,实时计算后视镜与障碍物在第二方向上的横向间距,第二方向与第一方向垂直,在横向间距小于或等于预设的第一阈值的情况下,判断后视镜在第一方向上接近障碍物的时间紧迫度是否小于或等于预设的第二阈值;若是,则控制对应的后视镜收起。本申请实现根据障碍物情况智能控制后视镜收起,减少了对于驾驶员的主观判断和驾驶经验的依赖,有效降低了后视镜发生横向碰撞的概率。
