According to the vehicle predictive cruise control method and device, the electronic equipment and the storage medium provided by the invention, the vehicle dynamic model which takes road gradient information into consideration, takes the vehicle speed, the engine torque and the vehicle longitudinal position as state variables and takes the engine target torque as the control variable is established; an oil consumption model with the vehicle speed and the engine torque as state variables is established; based on an optimal control problem which comprehensively considers vehicle driving economy, target vehicle speed following and comfort as cost functions, a deep neural network is taken as a carrier, an optimal control strategy is obtained through offline learning training, and the optimal control strategy is applied online to realize energy-saving type predictive cruise control. According to the method, the solving real-time performance of different prediction time domains can be met, the fuel economy is improved while the travel timeliness is ensured, and the application range of the solving method to different driving speeds and road working conditions is improved.

    本公开提供的车辆预测巡航控制方法、装置、电子设备和存储介质,本公开建立了考虑道路坡度信息,且以车辆速度、发动机转矩和车辆纵向位置作为状态变量,以发动机目标转矩作为控制变量的车辆动力学模型,并建立了以车辆速度、发动机转矩作为状态变量的油耗模型;基于综合考虑了车辆驾驶经济性、目标车速跟随和舒适性为代价函数的最优控制问题,以深度神经网络为载体,通过离线学习训练获得最优的控制策略,并在线应用最优控制策略,实现节能型预测巡航控制。本公开能够满足不同预测时域的求解实时性,保证行程时效性的同时改善了燃油经济性,并改善了求解方法对不同行驶速度和道路工况的适用范围。
