The invention discloses a low-speed electric vehicle pedestrian warning tone control system and method based on pedestrian position information. Belongs to the field of automobile safety equipment control and particularly relates to the field of electric vehicle safety equipment control. The problems that when a vehicle runs at a low speed and no one is in use, a warning tone is given out, and the warning tone is not high in pertinence are solved. The system comprises an image acquisition module, a central processing unit and a sound production module, the image acquisition module acquires information of objects around the electric vehicle in real time, establishes an object model and transmits the object model to the central processing unit; the central processing unit is used for judging and screening pedestrian information according to the object model, and inputting an audio signal and a control signal into the sound production module according to the pedestrian information; and the sound production module receives the audio signal, gives out a pedestrian prompt tone, receives the control signal and adjusts the sound pressure level of the pedestrian prompt tone. The system can be applied to the field of automobile safety equipment control, the field of electric vehicle manufacturing, the field of electric vehicle safety equipment control and the field of electric vehicle warning tone equipment manufacturing.
