Embodiment

[0024] Embodiment: a kind of configurable OBD diagnosis method comprises the following steps:

[0025] 1) Edit the display data, establish the target model, edit, sort and save the display data of the target model, including editing and sorting the byte length, offset, and accuracy of each display data, and all the data to be displayed After the data is edited, save the target model to generate a corresponding data display list. You can view the corresponding model and update the display list in the client, that is, the WeChat applet.

[0026] 2) Edit the CAN database, according to the sorting of the data display list in step 1), write the vehicle data protocol into the CAN database in the background of the diagnostic instrument, one display data corresponds to one CAN analysis data, and the CAN data of the vehicle data will also be requested. Write into the database, the OBD diagnostic device requests data and parses the data through the CAN database.

[0027] 3) Update the ...

Abstract

The invention relates to the technical field of vehicle self-diagnosis systems, and discloses a configurable OBD diagnosis method, which comprises the following steps: 1) editing display data, establishing a target vehicle model, and editing, sorting and storing the display data of the target vehicle model; 2) editing a CAN database, and according to the sorting of a data display list in the step 1), writing a protocol of vehicle data into a CAN database in a diagnostic instrument background, and writing the CAN requesting the vehicle data into the database; (3) updating the client, selecting the target vehicle model in the step (1) in the client, pushing a display list in the step (2) to the client by the diagnostic instrument background, and then pushing the CAN database to the OBD diagnostic instrument. According to the present invention, data of the OBD diagnosis equipment is configured through the OBD diagnosis background server, so that data reading of various vehicle types is realized, products are universalized as much as possible to adapt to more vehicle types, and the use cost is saved while the use convenience of a user is ensured.

Description

technical field [0001] The invention relates to the technical field of vehicle self-diagnosis systems, in particular to a configurable OBD diagnosis method. Background technique [0002] As the country vigorously promotes new energy vehicles, new energy vehicles are now developing rapidly, technology changes are changing with each passing day, intelligence, networking, electrification and sharing are accelerating penetration, and more and more new energy vehicles are being produced. The stage needs to display different data to analyze the vehicle running status. [0003] At present, the commonly used method is to collect vehicle data by diagnostic equipment and send it to the handheld device for diagnosis. However, the existing diagnostic equipment supports relatively fixed vehicle models, and it is inconvenient for users to expand data requirements. The existing vehicle diagnostic equipment parses data relatively single. Volkswagen models can perform data display and diagn...
