Embodiment Construction

[0023] Such as figure 1 Shown is a flow chart of automatic generation of a vehicle ECU diagnostic software model described in the embodiment of the present invention. Firstly, the development requirements of the diagnosis are edited into a diagnosis requirement document, which serves as an overall guidance document for the development of the diagnosis software. Afterwards, the designer completes the writing of the diagnostic design specification according to the diagnostic requirement document, and the tester completes the diagnostic test specification according to the diagnostic requirement document. The above steps are the same as the existing technical solutions. The improvement of the present invention lies in the next steps.

[0024] After completing the diagnosis design specification, the designer no longer directly builds the Simulink model for each fault diagnosis logic according to the specification, but writes an automatic script and compiles a diagnosis data form....

Abstract

The invention relates to an automatic generation system and an automatic generation method of an electronic control unit (ECU) diagnosis software model of an automobile. The system comprises an automatic script and a diagnosis data form. The automatic script comprises a first automatic script and a second automatic script and can automatically read files, builds models and generates reports by means of matrix laboratory (MATLAB) platform. The diagnosis data form is used for managing parameter information of all fault clauses, and the parameter information includes fault ID, detection period, fault confirmation counting threshold, fault clearing counting threshold, fault indication lamp and fault processing mode. The first automatic script and the second automatic script respectively generate a diagnosis model and a test case. The system and the method have the advantage that the first automatic script conducts automation on modeling work, and the second automatic script conducts automation on formation of the test case. The system and the method remove original mechanical complex redundant manual work, greatly improve development efficiency and simultaneously reduce possibility for manual error to the minimum.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to an automatic generation system and method of an automobile ECU diagnosis software model. Background technique [0002] ECU (Electronic Control Unit) is an electronic control unit, which is a microcomputer controller in automotive electronics. It is the same as an ordinary single-chip microcomputer. ), data converter (A / D), and shaping, driving and other large-scale integrated circuits. The function of the ECU is to process various input information according to its built-in programs and data, and then output instructions to control the corresponding actuators. [0003] ECU's diagnostic software is an important part of its built-in program. Its task is to monitor its own hardware and software in real time, and properly handle various faults found, so as to ensure the safety of people and vehicles and speed up maintenance. Most of the current automotive ECU ...
