The invention discloses a predictive cruise control method and system for a commercial vehicle. The method comprises the steps that road gradient information provided by a high-precision map and a target cruise vehicle speed corrected by a deep belief network driving style model are obtained to serve as input parameters; according to the rotating speed and the torque of the engine, a weighted moving average algorithm is adopted to carry out averaging processing on the power value within a short period of time, and the current engine power is generated; on the basis of an automobile power balance equation, according to the current position and the slope value of the front road, the driving power requirement of the next slope section is predicted; and in combination with the efficient output power interval of the engine, the recommended gear and the optimal accelerator opening degree of the next slope section are generated according to different power demand conditions. Therefore, according to the predictive cruise control method for the commercial vehicle, the gears and the accelerator can be adjusted in a self-adaptive mode according to the road gradient and the driving habit, the driving efficiency and the fuel economy are improved, and the individuation of the driving experience is enhanced.

    本发明公开了一种商用车预测性巡航控制方法及系统,其中所述方法包括:获取高精度地图提供的道路坡度信息以及经过深度信念网络驾驶风格模型修正后的目标巡航车速作为输入参数;根据发动机转速和扭矩,采用加权移动平均算法对一小段时间内的功率值做平均化处理,生成当前发动机功率;基于汽车功率平衡方程,根据当前位置和前方道路的坡度值,预测下一坡段的行驶功率需求;结合发动机自身的高效输出功率区间,根据不同功率需求情况,生成下一坡段的推荐挡位及最佳油门开度。借此,本发明的商用车预测性巡航控制方法,可根据道路坡度和驾驶习惯自适应调整挡位和油门,提高了行车效率和燃油经济性,增强了驾驶体验的个性化。
