Embodiment Construction

[0029] The present invention will be further described in detail through specific embodiments below.

[0030] Such as figure 1 The vehicle remote fault diagnosis management method shown includes the following contents:

[0031] S1, when performing remote fault diagnosis management of the vehicle, the diagnostic instrument first sends a fault diagnosis request to the engine management subunit in the vehicle's electronic control unit, and the engine management subunit sends the fault diagnosis request to the diagnostic instrument in a flow control frame format A diagnostic response with the vehicle's fault code attached to the diagnostic response;

[0032] S2. The diagnostic instrument obtains the fault code according to the received diagnostic response, and then the diagnostic instrument sends the fault code to the service module in the background, the user's mobile terminal and the vehicle terminal on the vehicle. The database obtains the fault type information corresponding...

Abstract

The invention relates to the technical field of vehicle fault diagnosis, and particularly relates to a vehicle remote fault diagnosis management method and system. According to the method, the fault code of a vehicle and the corresponding fault information of the fault code are transmitted to a client terminal so that the vehicle owner is enabled to see the fault code and the fault information, the vehicle owner is enabled to send the vehicle to repair in time and the vehicle owner is also enabled to clearly know the information of his vehicle. The system comprises a diagnostic instrument, an electric control unit, a fault code database, a maintenance advice database, a user terminal and a service module. The diagnostic instrument acquires the fault code in the electric control unit and transmits the fault code to the service module. The service module matches the fault information in the fault code database according to the fault code and also matches the maintenance advice in the maintenance advice database. The service module transmits the fault information and the maintenance advice to the user terminal. The service center transmits the fault information to the user terminal, and the vehicle owner diagnoses the body data of the vehicle in real time to identify problems early so that the accidents can be reduced and the advice can also be provided for vehicle maintenance.

Description

technical field [0001] The invention relates to the technical field of vehicle fault diagnosis, in particular to a vehicle remote fault diagnosis management method and system. Background technique [0002] Modern automobiles have a high degree of intelligence, and the operation of the vehicle determines the power economy of the vehicle, whether it can meet emission regulations, meet safety regulations, and control stability. Due to technological progress and product upgrades, automotive electronic systems begin to be coupled and interact with each other. The failure of one system will affect the work of other systems, thereby attracting investment and concurrent failures, bringing safety hazards. At the same time, in the development, offline testing, and after-sales maintenance of automobile parts and vehicles, it is necessary to diagnose and visit the corresponding automotive electronic systems through OBD to obtain more status information including diagnosis. [0003] Som...
