Abstract

The information terminal for diagnosing fault of vehicle communicates with comm. unit of vehicle fault detection. The information terminal includes car borne information process unit and comm. interface. The comm. unit of vehicle fault detection is installed on vehicle. Remote monitor center includes information diagnosis and process unit. Through comm. interface setup in information terminal, the comm. unit of vehicle fault detection transfers diagnosis signal to car borne information process unit, which is also connected to radio transmission car borne terminal. Through radio comm. network, the radio transmission car borne terminal implements signal connection to information diagnosis and process unit. Thus, professional detector set can be used to carry out online detection diagnosis for running vehicle. Professionals on monitoring center can analyze and process detected data to direct driver to carry out necessary maintenance for vehicle.

Description

Technical field [0001] The present invention relates to a safety detection device and method of a vehicle, and more specifically to an information terminal and method for remote diagnosis of vehicle faults. The terminal and the method can detect the vehicle regularly and randomly, and monitor the running state of the vehicle in time, which is beneficial to guarantee the safe operation of the vehicle. Background technique [0002] Nowadays, the diagnosis of vehicles is usually carried out by users on a regular basis or after a serious problem in a certain aspect of the vehicle is discovered, and then sent to a specialized vehicle maintenance unit for diagnosis and repair. Since most users do not have the professional knowledge of vehicle maintenance and diagnosis and do not have professional testing tools, they cannot find some abnormal information that appears during the operation of the vehicle, so that the vehicle cannot be diagnosed, repaired and maintained in a timely manner....
