METHOD FOR CONTROLLING RANGE EXTENDER, AND RELATED DEVICE

A method for controlling a range extender includes obtaining a sound pressure level of environmental noises and obtaining a real-time fitted sound quality limit for a vehicle in a traveling procedure; processing the sound pressure level and the real-time fitted sound quality limit to obtain a sound pressure level margin, determining a working condition corresponding to a sound pressure level lower than or equal to the sound pressure level margin, and taking the working condition as a target calibration working condition; obtaining a respective corrected sound pressure level by performing correction through a correcting sound pressure function based on the sound pressure level and a respective sound pressure level of the range extender in each working condition; and comparing the real-time fitted sound quality limit corresponding to the target calibration working condition with a corresponding corrected sound pressure level, and adjusting the target calibration working condition based on the comparison.
