Abstract

The present invention proposes a vehicle remote diagnosis system and diagnosis method. The system includes a configuration device, an in-vehicle diagnosis unit and a remote diagnosis unit. The in-vehicle diagnosis unit and the remote diagnosis unit are connected through a wireless communication network. Entertainment system, in-vehicle bus and wireless communication module, the configuration equipment is connected to the vehicle infotainment system through the vehicle bus, and the vehicle infotainment system is used to receive user diagnostic commands, collect diagnostic data and send diagnostic data to the remote diagnostic unit through the wireless communication module package, and at the same time receive and display the diagnosis result data sent back by the wireless communication module. The present invention avoids the equipment and installation of separate diagnostic equipment by integrating the diagnostic module into the necessary vehicle infotainment system of the vehicle, and reduces the cost of the whole vehicle. The diagnosis can be realized by simple operation on the vehicle infotainment system , reducing the professional requirements of vehicle diagnosis, while greatly improving the performance and efficiency of remote diagnosis.

Description

technical field

[0001] The invention relates to the technical field of vehicle fault diagnosis, and more specifically relates to a vehicle remote diagnosis system and a diagnosis method. Background technique

[0002] Vehicle diagnostic technologies in the prior art are generally divided into two categories: one is to use a diagnostic instrument to connect to the vehicle's internal bus, read the ECU module fault code in the vehicle, and then perform vehicle fault diagnosis based on the diagnostic instrument and related equipment. This diagnosis method needs to drive the vehicle to a specific place for implementation, and requires specialized personnel to operate, which is relatively professional. In the prior art, most vehicles go to 4S stores for detection and diagnosis. Another type of vehicle diagnostic technology is the Internet-based remote diagnostic technology developed in recent years. This diagnostic technology realizes vehicle diagnostics by configuring relevant dia...
