The invention relates to the technical field of vehicle collision avoidance, and discloses a vehicle collision avoidance method, device and equipment, and the method comprises the steps: when a vehicle turns, preliminarily determining whether a target two-wheeled vehicle is on a driving track of the vehicle according to the predicted position information of the vehicle and the target two-wheeled vehicle at the first collision time and the second collision time, and if yes, determining that the target two-wheeled vehicle is on the driving track of the vehicle; if so, taking the two-wheeled vehicle as a preliminary risk target; determining an important risk target according to the first collision time and the second collision time of the initial risk target, the relative distance between the vehicle and the initial risk target, and the relationship between the initial risk target and the driving track of the vehicle when the initial risk target takes the collision avoidance action; and when the vehicle decelerates to avoid collision, determining a target deceleration according to a preset deceleration calculation rule, and determining whether to trigger automatic emergency braking according to the relationship between the target deceleration and the preset deceleration. According to the application, under the condition that one camera is arranged, whether the automatic emergency brake is triggered or not can be accurately judged.
本申请涉及车辆避撞技术领域,公开了一种车辆避撞方法、装置及设备,该方法包括:在自车转弯时,根据自车与目标两轮车在第一碰撞时间和第二碰撞时间的预测位置信息初步确定目标两轮车是否在自车的行驶轨迹上,若在,则将该两轮车作为初步风险目标;根据初步风险目标的第一碰撞时间、第二碰撞时间、自车与初步风险目标的相对距离及初步风险目标在采取避撞动作时与自车的行驶轨迹的关系,确定重要风险目标;在自车采取减速进行避撞时,根据预设减速度计算规则确定目标减速度,并根据目标减速度与预设减速度的关系,确定是否触发自动紧急刹车。通过本申请,在设置一个摄像头的情况下,即可准确判断是否触发自动紧急刹车。
