Method for calibrating parameters of vehicle-mounted sound equipment

The invention discloses a method for calibrating parameters of vehicle-mounted sound equipment, which comprises the steps that (1) a PC (personal computer) is connected to a vehicle-mounted sound equipment host through a UART mode so as to establish communication connection, and parameters to be calibrated of the vehicle-mounted sound equipment host are acquired; (2) the PC carries out debugging according to the acquired parameters to be calibrated; and (3) a calibrated parameter file Calibration_file is generated, and the calibrated parameter file Calibration_file is downloaded to an EEPROM (Electrically Erasable Programmable Read-Only Memory) of the vehicle-mounted sound equipment host through a CAN tool. According to invention, automobile sound systems can be calibrated automatically according to different vehicle models when automobiles leave the factory; an automobile internal installation environment is well kept by using a special connection mode, and debugging can be carried out outside the automobiles, thereby avoiding acoustical interference formed by debugging performed in the automobile; calibration for the parameters of the vehicle-mounted sound equipment host is realized conveniently and efficiently through real-time effect debugging and graphical debugging; repeated development is avoided, and the research and development cost is reduced.
