The invention provides a cruise control method, device, storage medium and system for a vehicle, and the method comprises the steps: correcting a vehicle cost function through employing a rolling resistance coefficient, and obtaining a corrected vehicle cost function of each section in a preset road; therefore, compared with an existing scheme, the optimal vehicle speed can be obtained more accurately by only considering the gradient, and in addition, under the condition that the vehicle running cost of the corrected vehicle cost function of the section meets the minimum value in the section, the corresponding vehicle speed is determined as the optimal vehicle speed of the section. Therefore, the optimal vehicle speed can be obtained on the basis of minimizing the cost required for vehicle driving, compared with an existing scheme, the cost required for vehicle driving can be reduced, and then the problem that the precision of vehicle speed control is low due to the fact that the cruise control of the existing scheme only depends on the current gradient to control the vehicle speed is solved.
本申请提供了一种车辆的巡航控制方法、装置、存储介质和系统,该方法通过采用滚阻系数来对车辆成本代价函数进行修正,得到预设道路中各区段的修正后的车辆成本代价函数,从而相比现有方案仅考虑坡度可以更为精确地得到最有车速,另外在区段的修正后的车辆成本代价函数的车辆行驶所需成本满足区段内的最小值的情况下,确定对应的车速为区段的最优车速,从而可以让车辆行驶所需成本最小化的基础上来得到最优车速,相比现有方案可以降低车辆行驶所需成本,进而解决了现有方案的巡航控制仅依靠当前坡度来控制车辆的速度,从而造成对车辆的速度控制的精确度较低的问题。
