Problems solved by technology

However, this method only implements a form of communication for remote diagnosis, and the mobile terminal used is a desktop computer, which cannot be applied to small-sized mobile terminals, such as mobile phones, because the communication medium of small-sized mobile terminals is often different from that of desktop computers. The communication media of different machines are different, therefore, the communication form of remote diagnosis is also different

no. 1 example

[0026] In this embodiment, the mobile terminal obtains vehicle data through Bluetooth technology, and performs diagnosis and processing according to the obtained vehicle data.

[0027] figure 1 It is a structural diagram of a system for a mobile terminal to diagnose vehicle data according to the first embodiment of the present invention. Below, will refer to figure 1 This embodiment will be described.

[0028] First, the diagnostic software 12 developed by the manufacturer of the diagnostic instrument needs to be downloaded on the mobile terminal 1 with the Bluetooth device 11 (currently the diagnostic software has been developed quite maturely).

[0029] Such as figure 2As shown, currently existing diagnostic software generally includes a real-time data stream reading module 10, a fault code reading and clearing module 20, a freeze frame management module 30, a system fault processing module 40, a peripheral interface 50 and other auxiliary devices according to functional...

[0038] In this embodiment, the mobile terminal obtains the vehicle data through USB communication. This embodiment is applicable to vehicle-mounted systems that do not have a standard Bluetooth device.

[0039] image 3 It is a structural diagram of a system for a mobile terminal to diagnose vehicle data according to the second embodiment of the present invention. Such as image 3 As shown, at first, download the diagnostic software 12 in the mobile terminal 1 with the USB interface 13, and also need to integrate the USB conversion module 29 into the vehicle-mounted USB device 28 in the vehicle-mounted system 2, wherein, the USB conversion module 29 is used for The vehicle data read from the vehicle control system through the CAN bus is converted into data in DAT format (a commonly used data format). Likewise, these data can be remotely sent to the mobile terminal 1 in various forms such as text.

[0040] For example, the USB conversion module 29 can adopt the CH376 chip (...

Abstract

The invention provides a method for diagnosing vehicle data by using a mobile terminal, which comprises the following steps of: downloading diagnosis software on the mobile terminal; integrating a Bluetooth conversion module to a vehicle-mounted Bluetooth device or integrating a USB (universal serial bus) conversion module to a vehicle-mounted USB device; reading the vehicle data from VMS (velocity-measuring system) through a CAN (controller area network) bus when the mobile terminal is communicated with the vehicle-mounted Bluetooth device through the Bluetooth apparatus thereof or connected to the vehicle-mounted USB device through the USB data line; and converting the format of the read vehicle data through the Bluetooth conversion module or the USB conversion module, then sending the data to the diagnosis software on the mobile terminal. Correspondingly, the invention provides a system for diagnosing vehicle data by using the mobile terminal. The vehicle data can be read to the mobile terminal through the Bluetooth or the USB data line, and can be diagnosed remotely through the diagnosis software on the mobile terminal.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a method and system for a mobile terminal to diagnose vehicle data. Background technique [0002] At present, automobile faults can only be detected by using a special-purpose diagnostic instrument at a maintenance service station, and this special-purpose diagnostic instrument is generally expensive and far from being popularized. Drivers often don't know anything about car failures. When a car breaks down, they can only go to a maintenance service station for repairs. This situation causes the driver to be unable to understand the vehicle condition at the first time, perform instant diagnosis, and handle some minor faults that can be handled by himself. Especially when the driver ran into a breakdown in some remote areas, it was inconvenient to go to the maintenance service station for repairs. Therefore, expect a kind of method that can carry out real-time fault det...
