The objective of the present application is to provide a method and apparatus for processing real-time vehicle operating data, aiming at solving the technical problem that car owners couldn't obtain real-time vehicle operating data to ensure safety via an existing vehicle-mounted system. The method comprises: obtaining real-time vehicle operating data from an electronic control unit of the vehicle via a vehicle bus; reading the real-time vehicle operating data from a serial port; determining whether there is data that needs to be answered in the real-time vehicle operating data and storing the real-time vehicle operating data into a data queue whose data need to be answered and a data queue whose data doesn't need to be answered respectively after the determination; transmitting the real-time vehicle operating data to a background server, so that the background server can provide current vehicle with diagnostic message or service information. Compared with the prior art, the method provided in the embodiment of the present application can provide car owners with remote diagnosis or remote service conveniently, thereby reducing various costs of using cars.
