The invention relates to a range extender control method, system and equipment based on an application scene. The method comprises the steps that the current cooling liquid temperature of an engine is collected; determining a starting torque according to the current cooling liquid temperature, and controlling the engine to start according to the starting torque; collecting the current gradient, the current speed and the current altitude; determining a current road condition according to the current gradient, and obtaining to-be-generated power based on the current road condition and the current speed; comparing the current altitude with a preset altitude threshold value; if the current altitude is larger than the altitude threshold value, the to-be-generated power is adjusted according to an efficiency curve, target generated power is obtained, the efficiency curve is used for indicating the mapping relation among the torque, the rotating speed, the power and the efficiency of the range extender, and the target generated power is located in a target efficiency interval of the efficiency curve; and controlling the range extender to generate power according to the target generated power. By adopting the method, the compatibility of the control mode of the range extender in the prior art can be improved.

    本申请涉及一种基于应用场景的增程器控制方法、系统和设备。所述方法包括:采集发动机的当前冷却液温度;根据当前冷却液温度确定启动扭矩,并控制发动机按照启动扭矩启动;采集当前坡度、当前速度以及当前海拔高度;根据当前坡度确定当前路况,并基于当前路况以及当前速度获得待发电功率;对比当前海拔高度与预设的海拔高度阈值;若当前海拔高度大于海拔高度阈值,根据效率曲线调整待发电功率,获得目标发电功率,其中,效率曲线用于指示增程器的扭矩、转速、功率以及效率之间的映射关系,目标发电功率位于效率曲线的目标效率区间内;控制增程器按照目标发电功率进行发电。采用本方法能够提高现有技术中增程器的控制方式的兼容性。
