Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 As shown, the implementation steps of the method for remote diagnosis of automobile faults of the present invention are as follows: a control center 9 is set, and the control center 9 includes a computer server, an automobile diagnostic expert, and an automobile information database; and an on-board intelligent terminal 11 is installed in the user's vehicle.

[0028] After the vehicle-mounted intelligent terminal 11 obtains the fault codes and data streams of the automobile, they transmit them to the control center 9 through the public wireless communication network 10 .

[0029] The control center 9 transmits the diagnostic results to the vehicle-mounted intelligent terminal 11 for display through the public wireless communication network 10 .

[0030] Furthermore, when the control center 9 receives the vehicle diagnos...

Abstract

The invention discloses a remote diagnosis method for vehicle faults and a vehicle-mounted intelligent end device thereof. When vehicles break down in the open, drivers can call the control center through a communication network, and an expert system in the center is connected with a vehicle-mounted vehicle diagnosis unit through the communication network; the vehicle diagnosis unit transmits relevant information, such as fault codes, data flows and the like to the control center; the relevant information is analyzed by the expert system, or analyzed by vehicle maintenance experts of expert seats in the control center to give fault reasons so as to help drivers to repair vehicles. Thus, simple faults can be repaired by drivers on site, and the control center will provide a nearest maintenance factory for serious faults. The invention can be used for vehicle regular diagnosis and maintenance, and the communication system of the invention can be used as a vehicle-mounted telephone.

Description

(1) Technical field [0001] The invention relates to an implementation method of a vehicle diagnostic system. Specifically, it is a method for remote diagnosis of automobile faults. It also relates to a vehicle-mounted intelligent terminal device used to realize the remote diagnosis method for vehicle faults. (two), background technology [0002] With the rapid growth of China's economy, the number of cars in China is increasing at a rate of millions every year. In the past, most of the drivers of vehicles were professional drivers, and they all had certain knowledge of car repair and maintenance. When a car broke down in the field, they would Have a certain fault handling ability. Nowadays, there are more and more private cars. Due to the different occupations of non-professional drivers, the knowledge of car repair and maintenance is relatively lacking. When cars break down in the wild, they are often at a loss. In addition, when and what kind of maintenance should be ca...
