Combination instrument interface fault display method

Abstract

The invention provides a method for displaying faults on the interface of a combination meter, which is characterized in that it includes the following steps: a. After power-on, the combination meter displays a startup animation; b. Judging whether there is a pop-up fault, and if so, execute step c; if If not, execute step d; c. Display all pop-up fault information in turn. After the round robin, execute step d; d. Display the main interface and judge whether there is a text reminder fault. If there is, execute step e; if not, then Execute step f; e. display the main interface, and display text reminder fault information at the same time, switch the content of text reminder fault information according to an external command; f. display the main interface, and display the current vehicle speed at the same time. The object of the present invention is to address the defects of the prior art and provide a method for displaying faults on the interface of a combined instrument, which simplifies the switching logic and ensures the scalability of the software by classifying events and defining the logic of the array.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for displaying faults on an interface of a combination instrument. Background technique [0002] The display logic of the current interface is as follows: Assuming that the same type of events to be displayed are A, B, and C (priority from high to low), the fault information is displayed cyclically according to the priority. If a new requirement is added at this time, it is necessary to add an interface display event D, and the priority of D is between A and B, the software logic needs to be changed again, and the judgment of event D is inserted after A, and the judgment of event D is judged after completion time B. The defect of the existing technology is that the faults are judged and displayed one by one according to the priority. When the high priority appears, the interface can only see the high priority fault, but not the low priority fault; when the new requi...

Problems solved by technology

The defect of the existing technology is that the faults are judged and displayed one by one according to the priority. When the high priority appears, the interface can only see the high priority fault, but not the low priority fault; when the new requirement changes, the priority needs to be rearranged. level, re-changing the software requires a large workload and a long change cycle; as the vehicle has more and more functions, more and more events need to be displayed, and the existing solutions are becoming more and more complicated in terms of implementation logic, which leads to changes in the reliability of the software.
