The invention relates to an electric heavy truck fleet battery replacement beat planning and vehicle predictive cruise control method, which comprises the steps of sending a vehicle battery replacement state and vehicle queuing data of a battery replacement station to a target fleet, and receiving the time of arriving at the power swap station and/or the time of departure sent by each vehicle in the target vehicle team based on the vehicle power swap state and the vehicle queuing data, determining the upper limit and the lower limit of the speed of each vehicle according to the time of arriving at the power swap station and/or the time of departure, and performing speed planning on each vehicle by using a predictive cruise algorithm. And obtaining a speed sequence formed by the speeds of the road points in the driving road section of the target motorcade, and performing cruise control on each vehicle according to the sequence. Therefore, the problems that an electric heavy truck fleet cannot know the condition in the battery replacing station in advance and cannot reasonably plan the vehicle speed, and energy is wasted when the electric heavy truck runs uphill and downhill due to the fact that the vehicle runs based on the set speed are solved, the predictability of battery replacing beat decision planning is improved, and energy is saved.
本申请涉及一种电动重卡车队换电节拍规划与车辆预测性巡航控制方法,包括:将换电站的车辆换电状态和车辆排队数据发送至目标车队,接收目标车队内每辆车辆基于车辆换电状态和车辆排队数据发送的到达换电站时间和/或发车时间,根据到达换电站时间和/或发车时间确定每辆车辆的速度的上下限,利用预测性巡航算法对每辆车辆进行速度规划,得到目标车队行驶路段中每一处路点的速度组成的速度序列,并根据该序列对每辆车辆进行巡航控制。由此,解决了电动重卡车队不能提前得知换电站内的情况而无法合理规划车速,以及因车辆基于设定的速度行驶而导致电动重卡在上下坡行驶中出现能量的浪费等问题,提高换电节拍决策规划的预见性且节约能源。
