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

[0028] In this embodiment, the mobile terminal acquires the vehicle data through the Bluetooth technology, and performs diagnosis and processing according to the acquired vehicle data.

[0029] 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.

[0030] First, it is necessary to download the diagnostic software 12 developed by the manufacturer of the diagnostic instrument on the mobile terminal 1 with the Bluetooth device 11 (the diagnostic software has been developed quite maturely at present).

[0031] like figure 2 As shown, the 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 the...

[0040] In this embodiment, the mobile terminal acquires vehicle data through USB communication. This embodiment is applicable to a vehicle-mounted system without a standard Bluetooth device.

[0041] 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. like image 3 As shown, first, the diagnostic software 12 is downloaded in the mobile terminal 1 having the USB interface 13, and the USB conversion module 29 needs to be integrated into the in-vehicle USB device 28 in the in-vehicle system 2, wherein the USB conversion module 29 is used to convert the 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.

[0042] For example, the USB conversion module 29 can use CH376 chip (this chip is a p...

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 present invention relates to the technical field of mobile terminals, and in particular, to a method and system for diagnosing vehicle data by a mobile terminal. Background technique [0002] At present, car faults can generally only be detected by using a special diagnostic instrument at a maintenance service station, and such a special diagnostic instrument is generally expensive and far from reaching the level of popularization. Drivers are often ignorant of car failures, and when the car breaks down, they can only go to the maintenance service station for repairs. This situation prevents the driver from being able to understand the vehicle condition in the first place, conduct instant diagnosis, and deal with some minor faults that can be completely handled by themselves. Especially when the driver encounters a fault in some remote areas, it is even more inconvenient to go to the maintenance service station for repair. Therefore, there is a n...
