Abstract

The invention discloses a method and a system of electronic control unit (ECU) hardware-in-loop simulation automated testing. The method comprises the following steps: a test form is filled in so that one or a plurality of test form cases, an automation code is run to enable the form test cases to generate executable files for testing, the test is executed, and a test report is generated. An automated interpreter code is needed to design only once and is permanently effective, and an automated testing development engineer is enabled to be out of a lot of test case code translation work. By adoption of a form test case development mode, the method and the system of ECU hardware-in-loop simulation automated testing are simple, efficient, universal and flexible, and cost performance is high and practical. After a lot of form tests are developed by a testing project, corresponding executable test cases are generated by queue with one key and are automatically executed with one key, so that hardware-in-loop (HIL) automated testing of the ECU is achieved in the real sense.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to an ECU hardware-in-the-loop simulation automatic testing method and system. Background technique [0002] ECU (Electronic Control Unit) electronic control unit, also known as "driving computer", "vehicle computer" and so on. In terms of use, it is a microcomputer controller for automobiles, also called a single-chip microcomputer for automobiles. It is the same as ordinary single-chip microcomputer, it is composed of microprocessor (CPU), memory (ROM, RAM), input / output interface (I / O), analog-to-digital converter (A / D), and shaping, driving and other large-scale integration. Circuit composition. The electronic control unit is composed of a microcomputer, input, output and control circuits. [0003] The automotive electronic control system includes three parts: sensors, ECU and actuators. The sensor is the interface for the ECU to collect various information of the car (...
