The invention discloses a remaining mileage prediction method of a pure electric vehicle. The remaining mileage prediction method comprises the steps that the theoretical remaining mileage is obtained according to battery remaining energy of remaining mileage updating time and vehicle driving energy consumption obtained by calculating in the period from vehicle startup time and the remaining mileage updating time; the ideal remaining mileage is obtained according to a remaining mileage initial value of the vehicle startup time and the actual driving mileage driven in the period from the vehicle startup time to the remaining mileage updating time; and the theoretical remaining mileage and the ideal remaining mileage are subjected to weighted processing, and the prediction remaining mileage is obtained. The theoretical remaining mileage and the ideal remaining mileage of the remaining mileage updating time are subjected to weighted processing, so that the remaining mileage is corrected according to different stages of the battery remaining electric quantity, and the accuracy and reasonability of remaining mileage prediction are improved. The invention further discloses a prediction controller and a prediction system based on the remaining mileage prediction method.
Description
technical field [0001] The invention relates to the technical field of pure electric vehicles, in particular to a method for estimating the remaining mileage of pure electric vehicles. It also relates to an estimation controller and estimation system based on the remaining mileage estimation method. Background technique [0002] Energy crisis, environmental pollution and greenhouse effect are becoming more and more serious, making new energy vehicles an inevitable trend in the transformation of the automotive industry. Pure electric vehicles have the advantages of high efficiency, energy saving, and terminal zero emissions, and have attracted extensive attention from scientific research institutions and enterprises. The estimation of the remaining mileage of pure electric vehicles can give a good reminder to drivers and become the focus of research in the field of pure electric vehicles. one. [0003] Driving conditions and battery power have a great influence on the estim...
