The invention discloses a control method for intelligently identifying long downhill and intelligently switching energy recovery intensity, which comprises the following steps: step S10, a driver selects an energy recovery mode, if the driver selects a level 1, a level 2, a level 3 or an intelligent auto mode, the step S20 is carried out, and if the driver selects a long downhill mode, the step S30 is carried out; step S20, judging whether the whole vehicle is in a long downhill mode or not by the VCU of the whole vehicle according to the following conditions, if so, executing the step S40, and if not, continuing to execute the current mode and repeating the judgment; and S30, whether the whole vehicle meets the condition of entering the long downhill mode or not is judged through the VCU, if yes, the step S40 is executed, and if not, selection fails, the step S10 is executed again, and the driver conducts mode selection again. According to the invention, the endurance mileage can be prolonged, the energy waste is reduced, the use of a brake system is reduced, the service life of the brake system is prolonged, and the safety is ensured.

    本发明公开了一种智能识别长下坡且智能切换能量回收强度的控制方法,包括以下步骤:步骤S10,驾驶员选择一种能量回收模式,若驾驶员选择等级1、等级2、等级3、或智能auto模式则进行步骤S20,若驾驶员选择长下坡模式则进行步骤S30;步骤S20,整车VCU通过以下条件来进行判定整车是否处于长下坡模式,若是则进行步骤S40,若否则继续进行当前模式且重复进行判定;步骤S30,通过VCU判定整车是否满足进入长下坡模式的条件,若是则进行步骤S40,若否则选择失败,返回至步骤S10,使驾驶员重新进行模式选择。本发明可以延长续航里程,减少能量浪费,同时也会减轻刹车系统的使用,提高制动系统的寿命和保证安全。
