The invention relates to the technical field of vehicles, in particular to a roar control method and device of a hybrid power vehicle, the vehicle and a storage medium, and the method comprises the following steps: obtaining an in-vehicle noise value of the hybrid power vehicle; if the in-vehicle noise value is greater than the roar threshold value, determining a target resonant frequency according to the engine speed; and determining a target rotating speed change slope and a target rotating speed adjustment interval of the engine according to the target resonant frequency, and controlling an in-vehicle noise value of the engine to be smaller than or equal to a roar threshold value according to the target rotating speed change slope and the target rotating speed adjustment interval. Therefore, the problem that in-vehicle roaring is caused by resonance generated by coupling with a vehicle body mode at a certain rotating speed during feed low-speed driving of the hybrid electric vehicle is solved.
本申请涉及车辆技术领域,特别涉及一种混合动力车辆的轰鸣控制方法、装置、车辆及存储介质,其中,方法包括:获取混合动力车辆的车内噪声值;若车内噪声值大于轰鸣阈值,则根据发动机转速确定目标共振频率;根据目标共振频率确定发动机的目标转速变化斜率和目标转速调整区间,根据目标转速变化斜率和目标转速调整区间控制发动机的车内噪声值小于或等于轰鸣阈值。由此,解决了混合动力汽车馈电低速行驶时在某一转速会与车身模态耦合产生共振,导致车内轰鸣的问题。
