Problems solved by technology

[0004] The other is to associate different data with the freeze frame corresponding to each diagnostic trouble code in the vehicle controller code. In addition, in the early stage of vehicle controller software development, the relationship between faults and data may not be clear, and the possibility of demand changes in the later period may make the relevant data displayed incomplete.

Abstract

The invention discloses a data display method and a data display system for freeze frames. The data display method comprises: sending a diagnosis request to a vehicle controller to obtain and analyze freeze frames corresponding to diagnosis failure codes from the vehicle controller; screening a plurality of data according to a determined display requirement to obtain associated data related to the diagnosis failure code; and displaying the data value of the associated data at the failure time. According to the present invention, by increasing the display requirement part related to the diagnosis failure codes, the associated data can be displayed when the freeze frames corresponding to the diagnosis failure codes freeze the same data, such that the failure positioning time can be saved during the maintenance, and the development cost can be saved during the software development.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a freeze frame data display method and system. Background technique [0002] In related technologies, there are generally two methods for processing freeze frames: [0003] One is to simplify the code implementation in the vehicle controller, use the CAN bus communication between the diagnostic instrument and the vehicle controller, and freeze the fault time value of the same data in the freeze frame of all diagnostic fault codes through the diagnostic protocol requirements (due to The time when the fault occurs is different, and the actual data value captured is different), on the display interface of the diagnostic instrument, the data corresponding to each diagnostic fault code is the same (the value of the data is different), and maintenance personnel need to find the same Diagnose the data related to the trouble code, and then analyze it, which greatly increases the wor...
