The invention discloses a vehicle control unit and a method and device for determining the remaining driving mileage of a vehicle, and the method comprises the steps: obtaining an energy consumption comparison table and historical driving data of the vehicle, and obtaining a target driving state of the vehicle in a to-be-driven line according to the historical driving data; the energy consumption comparison table is a corresponding relation table between the vehicle energy consumption of the vehicle and different driving states, so that the driving energy consumption of the to-be-driven route can be determined in the energy consumption comparison table according to the target driving state, and then the remaining driving mileage of the vehicle is determined according to the remaining electric energy and the driving energy consumption of the power battery of the vehicle. According to the method, the historical driving data of the vehicle and the target driving state of the to-be-driven route are combined, and the data advantages of the historical driving data and the target driving state are combined together, so that the scientificity of residual driving range calculation and the precision of a calculation result are greatly improved, and the accuracy of determining the residual driving range of the vehicle is further improved.
本发明公开了一种整车控制器、车辆剩余续驶里程的确定方法和装置,确定方法通过获取车辆的能耗对照表和历史行驶数据,根据历史行驶数据获得车辆在待行驶线路的目标行驶状态,由于能耗对照表为车辆的车辆能耗与不同行驶状态之间的对应关系表,因而可以根据目标行驶状态,在能耗对照表中确定出待行驶线路的行驶能耗,再根据车辆的动力电池的剩余电能和行驶能耗,确定出车辆的剩余续驶里程。该方法结合了车辆的历史行驶数据和待行驶线路的目标行驶状态,将两者数据优势结合在一起,极大提升了剩余续驶里程计算的科学性和计算结果的精度,进而提高了车辆剩余续驶里程确定的准确性。
