The invention discloses a self-adaptive cruise control method, system and equipment based on target driving mileage, and the method comprises the steps: determining target driving mileage information after a driver inputs a navigation destination in a navigation aided driving mode, and obtaining the current remaining driving mileage information of a vehicle in real time; determining an energy-saving coefficient according to the target driving mileage information and the current remaining driving mileage information; dynamically selecting a weight matrix in an adaptive cruise LQR controller through a fuzzy controller according to the energy-saving coefficient; determining an expected acceleration at the current moment according to the weight matrix; and when the energy-saving coefficient is within a preset threshold range, performing adaptive cruise control according to the expected acceleration at the current moment. The energy-saving coefficient is calculated in real time according to the target driving mileage information required by navigation and the current remaining driving mileage information, the vehicle following control mode of the self-adaptive cruise system is adjusted according to the energy-saving coefficient, and coordination of safety and economical efficiency of the vehicle self-adaptive cruise system is achieved.

    本发明公开了一种基于目标行驶里程的自适应巡航控制方法、系统及设备,所述方法包括:在进入导航辅助驾驶模式下驾驶员输入导航目的地后,确定目标行驶里程信息,实时地获取车辆的当前剩余续驶里程信息;根据目标行驶里程信息和当前剩余续驶里程信息确定节能系数;根据节能系数通过模糊控制器动态选取自适应巡航LQR控制器中的权重矩阵;根据权重矩阵确定当前时刻的期望加速度;在节能系数处于预设阈值范围内时,根据当前时刻的期望加速度进行自适应巡航控制。本发明根据导航所需目标行驶里程信息和当前剩余续驶里程信息实时计算节能系数,根据节能系数调整自适应巡航系统的跟车控制方式,实现车辆自适应巡航系统安全性与经济性的协调。
