The invention discloses a self-adaptive cruise vehicle distance control method, device and equipment and a storage medium, and belongs to the technical field of automatic driving. According to the method, driving data, such as the vehicle speed and the longitudinal distance, of vehicles within a certain range are recognized through a real-time sensing system, the predicted collision time and the relative acceleration are calculated, and therefore the vehicles which possibly directly or indirectly cause collision in the vehicles are determined to be subjected to early warning marking; real-time collision risks of a plurality of vehicles are quantified by combining a collision risk assessment algorithm, so that the vehicles needing priority prevention are determined, the vehicle following distance is adjusted in real time, in addition, when the vehicles needing priority prevention are switched, vehicle control stability is ensured by limiting vehicle deceleration, and the situation that driving experience is affected by sudden braking is avoided. On the whole, according to the scheme, through real-time vehicle distance control and risk assessment, the collision risk brought to the front vehicle is reduced, the vehicle following safety of the vehicle in the complex traffic environment is remarkably improved, and the driving comfort and safety are improved.

    本发明公开了一种自适应巡航车距控制方法、装置、设备及存储介质,属于自动驾驶技术领域。本方法通过实时感知系统识别一定范围内车辆的行驶数据,如车速和纵向间距,计算出预计碰撞时间和相对加速度,从而确定车辆中可能直接或间接引发碰撞的车辆进行预警标记,结合碰撞风险评估算法以量化多个车辆的实时碰撞风险从而确定需要优先防范的车辆并实时调整跟车距离,此外,在优先防范车辆发生切换时,通过限制车辆减速从而确保车辆控制的平稳性,避免急刹车影响驾驶体验。整体而言,该方案通过实时的车距控制和风险评估,减少了由于对前前车带来的碰撞风险,显著提高了车辆在复杂交通环境中的跟车安全,提升了驾驶的舒适性和安全性。
