The invention relates to the technical field of electric vehicles, in particular to an extended-range electric vehicle control strategy, the whole vehicle is provided with three driving modes, namely a pure electric driving EV mode, a forced engine starting REV mode and an intelligent mode AUTO, in the EV mode, only a battery discharges to supply power to electric driving and other high-voltage accessories, and in the AUTO mode, only a battery discharges to supply power to other high-voltage accessories; in the REV mode, the engine is controlled to be in a running state all the time, power can be supplied to an electric drive, a battery can be supplemented, power can also be supplied to high-voltage accessories, and meanwhile the requirement for forcibly starting the engine for brand tail gas detection on a new vehicle can be met; and in the Auto mode, when the engine is started can be intelligently decided according to the electric quantity of the whole vehicle and the requirement of a driver. According to the invention, the problems that the fuel consumption is too high and the battery discharge depth is not enough to influence the economical efficiency of the vehicle use of the user due to the premature intervention of the APU are solved.
本发明涉及电动汽车技术领域,具体地说,本发明涉及一种增程式电动汽车控制策略,整车设置了三种驱动模式,分别为纯电驱动EV模式、强制启动发动机REV模式以及智能模式AUTO,EV模式为只有电池放电为电驱和其他高压附件供电,REV模式则控制发动机一直处于运行状态,既可以为电驱供电也可以为电池补电,还可以为高压附件供电,同时也可满足新车上牌尾气检测的强制启动发动机需求,Auto模式则会根据整车电量和驾驶员需求智能决策何时启动发动机,以及需要APU以多大的发电功率运行,解决了APU过早介入,则可能导致油耗过高,电池放电深度不够进而影响用户用车的经济性的问题。
