Vehicle system audio signal processing method and vehicle system

The present invention discloses a vehicle system audio signal processing method and a vehicle system. The vehicle system comprises a first system and a second system. The audio signal processing method comprises: the first system and the second system are configured to respectively receive first audio signals and second audio signals; the first audio signals and the second audio signals are subjected to signal processing to form third audio signals; and the third audio signals are output. The vehicle system is arranged as a dual system, wherein the first system can be an intelligent electronicproduct system which is popular on a current market, and the second system can be a traditional vehicle system. A vehicle system user's experience for processing vehicle audio can be obviously improved by means of the first system, identifiable compatible formats of vehicle audio processing can be widened, audio processing response time can be shortened, and a hardware structure of a dual systemis employed to perform mor
