Abstract

The invention provides a vehicle fault remote diagnosis system, which includes a remote diagnosis ECU and a remote diagnosis server. The remote diagnosis ECU is connected with a CAN bus of a vehicle. The remote ECU collects fault information stored in ECUs on the vehicle and collects real-time dynamic information of the vehicle according to the needs of a user. Meanwhile, the remote diagnosis ECU executes the real-time information interaction between the vehicle and the remote diagnosis server. The ECUs on the vehicle refer to all the other ECUs on the vehicle except the remote diagnosis ECU. The remote diagnosis server stores an ECU diagnosis database, the vehicle model and the vehicle VIN code information, sends the collected diagnosis request of the user to the remote diagnosis ECU, and converts fault data returned by the remote diagnosis ECU into a diagnosis result which is sent to the user. According to the invention, a faulty vehicle can be remotely diagnosed in real time, the influence of the remote diagnosis on the normal running of the vehicle is eliminated, and the vehicle driving safety is ensured.

Description

【Technical field】 [0001] The invention relates to a vehicle fault remote diagnosis system and method. 【Background technique】 [0002] The existing on-board diagnostic system needs to use a diagnostic instrument to perform on-site fault diagnosis on the vehicle. There are generally two types of diagnostic instruments, one is handheld, which is an independent device with a display screen, and the other is a hardware box connected to the vehicle. The software is installed on the notebook, and the software and hardware boxes on the notebook are combined as a set of diagnostic instruments. Using a diagnostic instrument for fault diagnosis cannot confirm the vehicle fault at the first time when the fault occurs, and the vehicle needs to be moved to a repair shop before using the diagnostic instrument for fault diagnosis. The timeliness of fault repair is poor and the maintenance time of the user is wasted. [0003] The "Remote Real-time Diagnosis Method for Vehicle Faults" with t...
