The invention discloses a method and a system for improving the endurance of a pure electric vehicle in a driving process. The method comprises the following steps: acquiring the current residual electric quantity of a vehicle, estimated power consumption, estimated vehicle speed and the working state of a shutdown function system which affects the power consumption; determining optimizable operations of the vehicle at the current moment according to the estimated vehicle speed of the vehicle at the current moment and the working state of the shutdown function system influencing the power consumption, and obtaining the optimized power consumption of each optimizable operation; according to the residual electric quantity and the estimated power consumption of the vehicle at the current moment and the optimized power consumption of each optimizable operation, calculating the residual endurance mileage of the vehicle at the current moment and a corresponding improvement value of the residual endurance mileage of the vehicle after each optimizable operation is implemented; according to the remaining endurance mileage of the vehicle at the current moment and the increasing value corresponding to the remaining endurance mileage of the vehicle after the implementation of each optimizable operation, one or more optimizable operations are implemented, and the remaining endurance mileage of the vehicle is increased.

    本发明公开了一种纯电动汽车行驶过程中续航提升方法及系统。该方法包括:获取车辆当前时刻的剩余电量、估算电耗和估算车速,以及影响电耗的可关闭功能系统工作状态;根据车辆当前时刻的估算车速和影响电耗的可关闭功能系统工作状态,确定车辆当前时刻可优化的操作,并获取各个可优化操作的优化电耗;根据车辆当前时刻的剩余电量和估算电耗,以及各个可优化操作的优化电耗,计算车辆当前时刻的剩余续航里程和各个可优化操作实施后车辆剩余续航里程对应提高值;根据车辆当前时刻的剩余续航里程和各个可优化操作实施后车辆剩余续航里程对应提高值,实施一个或多个各个可优化操作,实现提高车辆剩余续航里程。
