The invention discloses a pure electric mode control method for an extended-range electric vehicle, which comprises the following steps of: S10, starting the vehicle, and turning on an ON gear by a key; step S20, judging whether the driver selects an REV mode or not, if so, transferring to step S30, and if not, transferring to step S40; step S30, judging whether the driver selects an EV mode or not, if so, transferring to step S40, and if not, controlling the driving mode to enter an Auto mode by the VCU; step S40, judging whether an EV mode can be entered or not through the VCU, if yes, controlling the driving mode to enter the EV mode through the VCU, and if not, repeating the judgment; and S50, judging whether the REV mode can be entered or not through the VCU, if so, controlling the driving mode to enter the REV mode through the VCU, and if not, transferring to the step S40. Compared with a common driving mode control strategy, a pure electric driving control mode capable of protecting parts, ensuring the dynamic property and the economical efficiency and considering the drivability has better economical efficiency, the dynamic property and the drivability, and meanwhile, the parts are fully protected.
本发明公开了一种增程式电动汽车纯电模式控制方法,包括以下步骤:步骤S10,启动车辆,钥匙上ON挡;步骤S20,判断驾驶员是否选择REV模式,若是则转移至步骤S30,若否则转移至步骤S40;步骤S30,判断驾驶员是否选择EV模式,若是则转移至步骤S40,若否则VCU控制驱动模式进入Auto模式;步骤S40,通过VCU判断是否可以进入EV模式,若是则VCU控制驱动模式进入EV模式,若否则重复进行判定;步骤S50,通过VCU判断是否可以进入REV模式,若是则VCU控制驱动模式进入REV模式,若否则转移至步骤S40。本发明可以保护零部件、保证动力性和经济性,同时兼顾驾驶性的纯电驱动控制模式,相比普通驱动模式控制策略,具备更好的经济性、动力性和驾驶性,同时充分保护零部件。
