Vehicle fault remote detecting diagnosis system and diagnosis method thereof

Abstract

The invention discloses a vehicle fault remote detection diagnosis system and a relative diagnosis method, which arranges a fault detector and a vehicle communication terminal in vehicle and communicates information with a remote control center via the vehicle communication terminal to diagnose fault remotely. Via the inventive vehicle fault remote detection diagnosis system and relative diagnosis method, the remote control center can periodically process vehicle remote fault detection diagnosis, and vehicle user can actively send remote fault detection diagnosis request to the remote control center. The invention separates the fault detection and diagnosis to improve versatility, which can is applied in variable vehicles. The invention can detect and diagnose multiple systems of vehicle, on-time send the diagnosis result to vehicle user, clear fault code and turn off alarm lamp remotely via the diagnosis result.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a remote vehicle fault detection technology. Background technique [0002] At present, electronically controlled vehicles generally have a self-diagnosis interface, and vehicle repair shops can detect and diagnose the vehicle by connecting to this interface through a professional vehicle fault diagnosis instrument. For driving safety, vehicle users often need to go to the 4S shop or vehicle repair shop for maintenance or overhaul before regular or long-distance travel. When the vehicle has exceeded the free maintenance period, the vehicle user needs to drive the vehicle to the designated location for each maintenance and overhaul. At the same time, it is necessary to pay a high fee for each inspection, which not only increases the economic burden of the vehicle user, but also wastes the valuable time of the vehicle owner. In addition, when the vehicle is driving a...

For driving safety, vehicle users often need to go to the 4S shop or vehicle repair shop for maintenance or overhaul before regular or long-distance travel. When the vehicle has exceeded the free maintenance period, the vehicle user needs to drive the vehicle to the designated location for each maintenance and overhaul. At the same time, it is necessary to pay a high fee for each inspection, which not only increases the financial burden of the vehicle user, but also wastes the valuable time of the owner

In addition, when the vehicle is driving and finds that the vehicle warning indicator light is on, or the vehicle fails to continue driving, the vehicle user needs emergency rescue, and the rescue and maintenance organization can only know the cause of the vehicle failure after arriving at the scene. If all the parts that need to be replaced cannot be repaired on site, the vehicle can only be towed to the designated place by a tow truck for maintenance, which is very inconvenient
