Method for controlling range extender, and related device

An electronic device, comprising:

• a memory, a processor, and a computer program stored in the memory and executable by the processor, wherein the processor is configured to:
• obtain a sound pressure level of environmental noises and obtain a real-time fitted sound quality limit for a vehicle in a traveling procedure of the vehicle;
• process the sound pressure level of the environmental noises and the real-time fitted sound quality limit to obtain a sound pressure level margin, determine, from a pre-established working condition database of a range extender, a working condition corresponding to a sound pressure level lower than or equal to the sound pressure level margin, and take the working condition as a target calibration working condition of the range extender;
• obtain a respective corrected sound pressure level by performing correction through a correcting sound pressure function based on the sound pressure level of the environmental noises and a respective sound pressure level of the range extender in each working condition in the pre-established working condition database of the range extender;
• and
• compare the real-time fitted sound quality limit corresponding to the target calibration working condition of the range extender with a corresponding corrected sound pressure level, and adjust the target calibration working condition of the range extender based on a comparison result.

A non-transitory computer readable storage medium, having computer instructions stored thereon, which, when executed by a processor of a computer, the computer is caused to perform a method for controlling a range extender, the method comprising:

• obtaining a sound pressure level of environmental noises and obtaining a real-time fitted sound quality limit for a vehicle in a traveling procedure of the vehicle;
• processing the sound pressure level of the environmental noises and the real-time fitted sound quality limit to obtain a sound pressure level margin, determining, from a pre-established working condition database of the range extender, 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 of the range extender;
• obtaining a respective corrected sound pressure level by performing correction through a correcting sound pressure function based on the sound pressure level of the environmental noises and a respective sound pressure level of the range extender in each working condition in the pre-established working condition database of the range extender;
• and
• comparing the real-time fitted sound quality limit corresponding to the target calibration working condition of the range extender with a corresponding corrected sound pressure level, and adjusting the target calibration working condition of the range extender based on a comparison result.
