The invention relates to a vehicle cruise control method and device, a vehicle controller and a storage medium. According to the method, vehicle state data of a to-be-controlled vehicle at the current moment are obtained, and based on a target constraint condition, the vehicle state data at the current moment and a vehicle state space prediction equation, a target cost function including a battery capacity recession index is adopted for processing; target control data of the to-be-controlled vehicle for the next moment of the current moment is obtained, and then the to-be-controlled vehicle is controlled to run in the expected state according to the target control data. According to the embodiment of the invention, the target control data is solved by adopting the target cost function comprising the battery capacity recession index, so that the state of the controlled vehicle is close to the target as far as possible, the control action is as small as possible, the battery capacity recession is reduced, the endurance mileage is prolonged, and the service life of the battery is prolonged.
本申请涉及一种车辆巡航控制方法、装置、车辆控制器和存储介质。其方法通过获取待控制车辆当前时刻的车辆状态数据,并基于目标约束条件、当前时刻的车辆状态数据以及车辆状态空间预测方程,采用包括电池容量衰退指标的目标代价函数进行处理,得到待控制车辆针对当前时刻的下一时刻的目标控制数据,进而根据目标控制数据,控制待控制车辆跟随期望状态行驶。由于本实施例通过采用包括电池容量衰退指标的目标代价函数求解目标控制数据,从而可以使得施加控制后的车辆状态尽可能地接近目标,同时控制动作尽可能地小,从而减少电池容量衰退,提高续航里程及电池寿命。
