Automobile fault remote diagnosis system based on cellphone APP

Abstract

The invention discloses an automobile fault remote diagnosis system based on a cellphone APP. The system comprises cellphone APP software, a vehicle interface device, and a remote service center, the cellphone APP software sends a diagnosis request of a user to the remote service center via a mobile network, the remote service center sends a diagnosis command to the cellphone APP software according to the diagnosis request, the cellphone APP software forwards the diagnosis command to the vehicle interface device via a wireless network, and the vehicle interface device analyzes the diagnosis command, sets diagnosis protocol communication parameters with a to-be-diagnosed automobile electronic system, or sends a diagnosis request message to the to-be-diagnosed automobile electronic system via a vehicle network. According to the system, users can get the service of automobile fault diagnosis in a remote manner without increasing too much cost, the automobile fault diagnosis time is shortened, the manpower cost is reduced, and the automobile fault diagnosis efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobile electronic diagnosis, in particular to a remote diagnosis system for automobile faults based on a mobile phone APP. Background technique [0002] In the field of automotive fault diagnosis technology, the traditional fault diagnosis mainly adopts the scheme that technical personnel carry out fault diagnosis on the vehicle with professional equipment on site, which will have the following defects: [0003] 1. Since the traditional automobile fault diagnosis uses professional diagnostic equipment, it requires high skill level of the diagnostic personnel, the operation is complicated, the diagnosis efficiency of some faults is low, and it is easy to cause misjudgment, which brings difficulties to the vehicle fault diagnosis. [0004] 2. Since most of the traditional vehicle fault diagnosis requires on-site operation by professional technicians, it often cannot be diagnosed and repaired in time aft...

Problems solved by technology

[0003] 1. Since the traditional automobile fault diagnosis adopts professional diagnostic equipment, it requires high skill level of the diagnostic personnel, the operation is complicated, the diagnosis efficiency of some faults is low, and it is easy to cause misjudgment, which brings difficulties to the vehicle fault diagnosis

[0004] 2. Since most of the traditional vehicle fault diagnosis requires on-site operation by professional technicians, it often cannot be diagnosed and repaired in time after the vehicle breaks down, which has a certain lag

[0005] 3. Due to the long time period of traditional automobile fault diagnosis, the feedback of diagnosis results is not timely

[0006] 4. Due to the strong customization of traditional automotive fault diagnosis equipment, the applicability is low
