The invention relates to an idling charging power limiting method and device of a hybrid electric vehicle and a vehicle. The method comprises the steps that the actual scene where the hybrid electric vehicle is located is recognized, and whether the hybrid electric vehicle meets the preset idling charging starting condition or not is judged according to the actual scene; if the hybrid electric vehicle meets the preset idling charging starting condition, the voltage load power consumption interval and noise, vibration and sound vibration roughness NVH rotation speed limiting torque curve of the hybrid electric vehicle in the driving process are counted; and on the basis of the voltage load power consumption interval and the NVH limited rotating speed torque curve, the idle charging power of the hybrid electric vehicle is limited by using at least one whole vehicle parameter and the road information, so that a limiting result of the idle charging power is generated. Therefore, the problems that the vehicle part efficiency and the actual use scene are not comprehensively considered in the related technology, the optimal idling charging power of the vehicle is difficult to output, and the use experience of a user is reduced are solved.
本申请涉及一种混合动力汽车的怠速充电功率限制方法、装置及车辆,其中,方法包括:识别混合动力汽车所处的实际场景,并根据实际场景判断混合动力汽车是否满足预设怠速充电启动条件;若混合动力汽车满足预设怠速充电启动条件,则统计混合动力汽车在行车过程中的电压负载电耗区间和噪声、振动和声振粗糙度NVH限转速扭矩曲线;基于电压负载电耗区间和NVH限转速扭矩曲,利用至少一项整车参数和道路信息限制混合动力汽车的怠速充电功率,以生成怠速充电功率的限制结果。由此,解决了相关技术未综合考虑车辆部件效率和实际使用场景,难以输出车辆最佳怠速充电功率,降低了用户的使用体验的问题。
