The invention provides a hybrid electric vehicle engine output control method, a vehicle control unit and a hybrid electric vehicle. The method comprises the steps that whether noise data in a vehicle is larger than a noise limit threshold value or not is judged; if yes, the output of an engine of the hybrid vehicle is reduced to a preset range, and then subsequent steps are executed; and if not, directly executing the subsequent steps. Determining a current driving scene of the hybrid vehicle according to the data of the scene parameters, searching a noise threshold value corresponding to the current driving scene from a preset scene-noise database, and comparing the in-vehicle noise data with the noise threshold value; judging whether a preset noise control condition is met or not according to the comparison result, the current driving scene and the electric quantity of the battery; if yes, the hybrid electric vehicle is switched to be in a pure electric driving state; and if not, judging whether a preset noise control condition is met or not. According to the scheme, the state of the engine can be controlled according to the scene and the noise experience of the user, and the inductive noise experience feeling of the user is improved.

    本发明提供一种混动汽车发动机输出的控制方法、整车控制器及混动汽车,其中,方法包括:判断车内噪声数据是否大于噪声极限阈值;若是,则将混动汽车的发动机的输出降低至预定范围后执行后续步骤;若否,则直接执行后续步骤。根据场景参数的数据确定混动汽车的当前行驶场景,从预设的场景‑噪声数据库中查找对应于当前行驶场景的噪声阈值,并将车内噪声数据与噪声阈值进行比较,根据比较结果、当前行驶场景、以及电池电量判断是否满足预设的噪声控制条件;若满足,则将混动汽车切换为纯电行驶状态;若不满足,则判断是否满足预设的噪声控制条件。本方案可以根据场景和用户的噪声体验对发动机的状态进行控制,提高了用户的电感化噪声体验感。
