The invention provides a cruise vehicle speed control method and device, equipment, a storage medium and a program product, and relates to the technical field of vehicle intelligent driving assistance. The method comprises the following steps: acquiring jth to ith state information of a current vehicle; according to the road adhesion coefficient utilization rate corresponding to the weight of the current vehicle and the ith road adhesion coefficient estimated in real time, the ith maximum braking acceleration of the current vehicle is determined; calculating the ith minimum braking distance of the current vehicle according to the ith maximum braking acceleration and the ith actual vehicle speed of the current vehicle; and in the ith vehicle speed control period, the vehicle speed of the current vehicle is controlled according to the ith minimum braking distance and the state information. According to the method, the minimum braking distance is dynamically adjusted by applying the road adhesion coefficient utilization rate under different vehicle weights, the accuracy of the determined minimum braking distance is improved, and then the driving safety of the heavy commercial vehicle is improved.

    本申请提供一种巡航车速控制方法、装置、设备、存储介质及程序产品,涉及车辆智能驾驶辅助技术领域。该方法包括:获取当前车辆的第j个至第i个状态信息;根据当前车辆的重量对应的路面附着系数利用率、实时估计的第i个路面附着系数,确定当前车辆的第i个最大制动加速度;根据第i个最大制动加速度和当前车辆的第i个实际车速,计算当前车辆的第i个最小制动距离;在第i个车速控制周期内,根据第i个最小制动距离和状态信息,对当前车辆进行车速控制。本申请的方法,通过运用在不同车重下的路面附着系数利用率,动态调整最小制动距离,提高了确定出的最小制动距离的准确性,进而提高了重型商用车的行车安全性。
