The embodiment of the invention provides an emergency braking mode starting method and device and a medium. The emergency braking mode starting method comprises the following steps that vehicle peripheral information is obtained n times in a first period, and the number of times that a vehicle is located in a scene with the complex road condition is determined according to the vehicle peripheral information n times; wherein n is an integer greater than 0; if the frequency of the vehicle in the scene with the complex road condition reaches a preset frequency threshold value, updating the to-be-started frequency of the scene with the complex road condition; the to-be-started times of the scene with the complex road condition in the second period are obtained, and if the to-be-started times of the scene with the complex road condition in the second period reach a first preset threshold value, an emergency braking mode is started; the second period includes at least one first period. In this way, whether the vehicle is in an emergency can be judged by combining the road conditions of the surrounding area of the vehicle in multiple periods, and the risk that the auxiliary braking system mistakenly starts the emergency braking mode is reduced.
本申请实施例提供的一种紧急制动模式的启动方法、装置及介质。紧急制动模式的启动方法包括如下步骤:在第一周期内获取n次车辆周侧信息,并根据n次车辆周侧信息,确定车辆处于路况复杂的场景的次数;其中,n为大于0的整数;若车辆处于路况复杂的场景的次数达到预设次数阈值,则更新路况复杂的场景的待启动次数;获取第二周期内路况复杂的场景的待启动次数,若第二周期内路况复杂的场景的待启动次数达到第一预设阈值,则启动紧急制动模式;第二周期包含至少一个第一周期。如此可以结合多个周期内的车辆周围区域的路况判断车辆是否处于紧急情况,减小辅助制动系统误启动紧急制动模式的风险。
