The invention discloses an automobile whistle noise monitoring device, system and method. The automobile whistle noise monitoring system comprises a whistle noise identification module, a noise source positioning module and a camera shooting module; the whistle noise identification module filters sound waves with the frequency being smaller than or larger than that of the whistle noise through a band-pass filter which is arranged at the front end of a sound pickup according to frequency characteristics of the automobile whistle noise and then detects to determine whistle noise signals; the noise source positioning module positions based on multiple sound sources of ESPRIT algorithm; a specific matrix pencil is constructed and performed on generalized characteristic decomposition to obtain a translation operator which is corresponding to the direction of the sound source according to the translation invariance of signal subspace which is brought by translation invariance of a category of array through the ESPRIT algorithm and accordingly directional parameter estimation is obtained; the camera shooting shoots confirmed noise source searching points, marks violations and stores or transmits photos of marked violation vehicles to a related traffic management department.
