The invention provides a vehicle speed control method, device and equipment and a storage medium, and relates to the technical field of automobiles, and the vehicle speed control method comprises the steps that the real-time running speed and the real-time acceleration of a vehicle are collected through a vehicle-mounted sensor; the relative speed of the vehicle corresponding to an obstacle in front is collected through a hybrid radar; determining a current danger coefficient of the vehicle based on the relative speed, the real-time driving speed and the real-time acceleration; and controlling the vehicle to decelerate based on the expected acceleration corresponding to the danger coefficient. The danger coefficient is obtained through simultaneous operation of the real-time running speed and the real-time acceleration of the current running vehicle and the relative movement speed between the current running vehicle and the front obstacle, the acceleration of the vehicle is adjusted to the expected acceleration corresponding to the danger coefficient, and the vehicle is accurately controlled to rapidly and automatically decelerate when the vehicle is possibly in danger. Collision with obstacles is avoided, and the life safety of a driver is protected.

    本发明提出一种车速控制方法、装置、设备及存储介质,涉及汽车技术领域,所述车速控制方法的步骤包括:通过车载传感器采集车辆的实时行驶速度以及实时加速度;通过混合雷达采集所述车辆与前方的障碍物对应的相对速度;基于所述相对速度、所述实时行驶速度以及所述实时加速度,确定所述车辆当前的危险系数;基于所述危险系数对应的期望加速度,控制所述车辆进行减速。通过对当前行驶车辆的实时行驶速度、实时加速度以及与前方障碍物之间的相对移速进行联立获得危险系数,调整车辆的加速度至危险系数对应的期望加速度,精确地控制车辆在可能出现危险时,快速进行自动减速,避免与障碍物发生冲撞,保护驾驶员的生命安全。
