The invention belongs to the technical field of automobile braking, and discloses a vehicle high-speed braking method, device and equipment and a storage medium. The method comprises the following steps: acquiring driving parameters of a vehicle, and when judging that the vehicle has a front collision risk based on the driving parameters of the vehicle, performing first-stage deceleration on the vehicle based on ACC deceleration braking until the driving speed of the vehicle is decelerated to a reference speed; when the self-vehicle speed is the reference speed, second-stage speed reduction is conducted on the self-vehicle based on AEB emergency braking till self-vehicle braking is completed; when the collision risk exists in the high-speed driving process, the vehicle is decelerated through self-adaptive cruise control, after deceleration, the collision risk still exists, then the vehicle is decelerated through emergency braking until the vehicle stops, through combination of the two stages of self-adaptive cruise deceleration and emergency braking deceleration, the vehicle is decelerated in time when the collision risk exists at the high speed, and the vehicle is prevented from being damaged. Safety risks caused by emergency braking during high-speed driving are avoided, and meanwhile the danger of vehicle collision is effectively avoided.

    本发明属于汽车制动技术领域,公开了一种车辆高速制动方法、装置、设备及存储介质;该方法包括:获取自车行驶参数,基于自车行驶参数判断自车存在前方碰撞风险时,基于ACC减速度制动对自车第一阶段减速,直到自车的行驶速度减速至参考速度;在自车速度为参考速度时,基于AEB紧急制动对自车进行第二阶段减速,直到完成自车制动;本发明通过在高速行驶过程中存在碰撞风险时,通过自适应巡航控制对自车进行减速,减速后仍存在碰撞风险再通过紧急制动减速直到自车停止,通过自适应巡航减速和紧急制动减速两个阶段的结合,在高速存在碰撞风险时及时减速,避免高速驾驶时紧急制动带来的安全风险的同时有效避免车辆碰撞的危险。
