Embodiment Construction

[0025] The preferred embodiments of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0026] The core of the present invention for locating and analyzing the problems found in the development process of automotive electronic software is to first confirm the state information that the controller may need to use during analysis, and map them into a unique state table; Then add a state change recording module and a record upload communication mechanism in the controller software design, and establish a query mechanism; when in doubt, obtain the state change records through the query mechanism to analyze whether it is normal.

[0027] Such as figure 1 Shown is the method flow chart of a preferred embodiment of the present invention, is described in detail as follows in conjunction with vehicle body controller:

[0028] S101. Determine the state information to be recorded

[0029] In order to have enough information to a...

Abstract

The invention discloses a problem location method in the development process of automobile electronic software, comprising the following steps of: S101, determining state information which is to be recorded; S102, mapping the state information into a state table; S103, adding a state change record module; S104, adding a record uploading mechanism; S105, establishing a query mechanism; and S106, querying and analyzing reasons. The method of the invention carries out location correctly and shortens the software development time.

Description

technical field [0001] The invention relates to a problem location method in the development process of automobile electronic software. Background technique [0002] Diagnosis is used in various industries and automotive industries, but the object of diagnosis is basically peripheral devices, and the premise must be that the controller software itself is normal, and the purpose is to prepare for after-sales. There is no way to determine whether the software of the controller itself is normal. [0003] As the development of domestic brand automobiles advances from low-end products to mid-to-high-end products, there are more and more on-board controllers, and their control content is also increasing. The corresponding control logic is greatly complicated, and the interaction between systems will become frequent. The difficulty is increasing. In the process of product development, it is often found that the basic functions of a certain vehicle controller can already meet the ...
