The invention relates to the field of new energy automobile endurance control, in particular to a system and method for estimating endurance mileage of a new energy electric automobile, a VCU calculates battery energy consumption in real time, after a destination is reached, a navigation system calculates the total mileage of the journey and sends the total mileage to the VCU, the VCU calculates the average energy consumption of the journey, and the average energy consumption of the journey is calculated; storing the calculation result in a memory, calculating and recording energy consumption data again after driving the same route each time, calibrating storable times of the VCU, keeping the latest energy consumption data by the VCU, and taking an average value of the energy consumption data of multiple times as average energy consumption data; the current residual electric quantity and the average energy consumption of the battery are used for estimating the endurance mileage, so that the problems that certain deviation exists in estimation based on the electric quantity of the battery, the average energy consumption of driving for a period of time, whether an air conditioner is started or not and a driving mode at the present stage, the driving working condition and the environment can greatly influence the endurance estimation result, and the driving efficiency is low are solved. And the endurance mileage cannot be accurately estimated.
本发明涉及新能源汽车续航控制领域,具体地说,本发明涉及一种新能源电动汽车估算续航里程的系统及方法,VCU实时计算电池能耗,到达目的地后,导航系统计算出该行程的总里程,并发送给VCU,VCU计算本次的行程的平均能耗,将本次的计算结果储存在内存中,每次驾驶同样的路线后均会再次计算和记录能耗数据,对VCU进行标定可储存的次数,VCU保留最近的能耗数据,将多次的能耗数据的平均值作为平均能耗数据,并利用电池目前剩余的电量和平均能耗进行续航里程的估算,解决了现阶段都是基于电池电量、行驶一段时间的平均能耗、是否开启空调、驾驶模式来进行估算,都存在一定的偏差,且驾驶工况和环境都会对续航估算结果产生比较大的影响,无法准确估算出续航里程的问题。
