The invention discloses a control method of a dual-motor hybrid vehicle, a storage medium and the vehicle. The method comprises the following steps: acquiring an operation mode of a vehicle; when the vehicle is in the series drive mode, the engine demand power at the first moment is determined, and the engine demand power is the output power needed by the engine to meet all power demands of the vehicle; acquiring working condition information of the vehicle at the first moment, wherein the working condition information comprises at least one of the following information: an accelerator pedal opening value, a vehicle speed and a discharge power limit value of a power battery; acquiring engine demand power at a second moment; determining a power limit value based on the working condition information and the engine demand power at the second moment; and performing slope limitation on the engine demand power at the first moment based on the power limit value, and determining the engine target power. The technical problem that the NVH performance of the vehicle is poor due to the fact that the control method of the dual-motor hybrid power vehicle is unreasonable is solved.
本发明公开了一种双电机混合动力车辆的控制方法、存储介质及车辆。其中,该方法包括:获取车辆的运行模式;当车辆处于串联驱动模式时,确定第一时刻的发动机需求功率,其中,发动机需求功率为发动机为满足车辆的全部功率需求所需的输出功率;获取车辆在第一时刻的工况信息,工况信息包括如下至少之一:油门踏板开度值、车速、动力电池的放电功率限值;获取第二时刻的发动机需求功率;基于工况信息和第二时刻的发动机需求功率确定功率限制值;基于功率限制值对第一时刻的发动机需求功率进行斜率限制,确定发动机目标功率。本发明解决了由于双电机混合动力车辆的控制方法不合理导致的车辆的NVH性能差的技术问题。
