The invention provides a range extender database determination method, a range extender control method and related equipment, which can obtain corresponding sound wave data and sound pressure levels of a range extender under various working conditions to obtain a range extender database, determine the sound pressure level under the working condition of a vehicle according to the range extender database based on the working condition of the vehicle, and control the range extender according to the sound pressure level. The method comprises the following steps: acquiring a sound pressure level of a range extender, determining a current range extender frequency spectrum according to the sound pressure level, and subtracting the current range extender frequency spectrum from an acquired total noise frequency spectrum to obtain a background noise frequency spectrum, so that a corresponding masking domain can be determined by accurately combining various background noises in a vehicle driving process, and the range extender is operated and adjusted according to the masking domain. According to the method and the device, the masking region can cover the sound generated by the range extender of the vehicle, so that a user cannot perceive the sound generated by the range extender, the operation adjustment of the range extender can be continuously changed along with the environment sound change in the driving process, and the sound of the range extender can be always in a state of not interfering the user in the driving process.

    本申请提出了一种增程器数据库的确定方法、增程器控制方法及相关设备,能够获取增程器在各个工况下对应的声波数据和声压级得到增程器数据库,基于车辆的工况,并根据增程器数据库确定该车辆工况下的声压级,进而根据该声压级确定当前增程器频谱,将获取到的总噪声频谱减去该当前增程器频谱就能够得到背景噪声频谱,这样就可以准确结合车辆行车过程中的各种背景噪声确定对应的掩蔽域,根据该掩蔽域对增程器进行运行调整,保证该掩蔽域能够掩盖车辆的增程器产生的声音,使得用户不会感知增程器产生的声音,并且对增程器的运行调整会随着行车过程中的环境声音变化不断改变,保证行车过程中增程器的声音可以一直处于不会干扰用户的状态。
