Vehicle remote diagnostic system and diagnostic method

Abstract

The invention proposes a vehicle remote diagnostic system and diagnostic method. The system includes a configured device, an in-vehicle diagnostic unit and a remote diagnostic unit. The in-vehicle diagnostic unit is connected with the remote diagnostic unit through a wireless communication network. The in-vehicle diagnostic unit includes a vehicle-mounted information entertaining system, an in-vehicle bus and the wireless communication module. The configured device is connected with the vehicle-mounted information entertaining system through the in-vehicle bus. The vehicle-mounted information entertaining system is used for receiving a diagnosis command of a user, acquiring diagnostic data and sending diagnostic data packets to the remote diagnostic unit through the wireless communication module and at the same time receiving and displaying diagnostic result data transmitted back by the wireless communication module. Through integrating a diagnostic module into the vehicle-mounted information entertaining system which is necessary for a vehicle, the vehicle remote diagnostic system and diagnostic method avoid outfitting and installation of a single diagnostic device and reduce the cost of the whole vehicle. Diagnoses can be realized through simple operations on the vehicle-mounted information entertaining system so that professional requirements for the vehicle diagnoses are reduced and at the same time, remote-diagnosis performance and efficiency are improved greatly at the same time.

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...

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 diagnostic equipment inside the vehicle and sending diagnostic data to a remote terminal through a wireless network. Diagnostic function, this kind of specially equipped diagnostic equipment is expensive, and it needs to be specially equipped with a diagnostic display screen for this diagnostic equipment, which makes it extremely inconvenient to install the diagnostic equipment and display screen under the condition of limited space in the car, and additional diagnostic equipment Equipment and display screens will lead to an increase in the overall price of the vehicle, reducing the market competitiveness of the vehicle. In addition, various Internet-based vehicle diagnostic technologies in the prior art still have shortcomings such as unstable diagnostic performance and incomplete diagnostic functions.
