Abstract

The invention discloses an ECU software testing and calibrating system based on INCA, relates to the technical field of engine controller test and calibration, and solves the technical problem that the existing test and calibration mode is low in efficiency. The system comprises: a hardware-in-loop test system interface which is used for signal connection with a hardware-in-loop test system, and performing read-write operation on a test signal of a controlled model; an ASAM-3MC interface used for being in signal connection with an INCA calibration tool, monitoring signals of the ECU and calibrating parameters of the ECU; a file read-write module used for reading and writing parameters to quickly calibrate ECU software, reading a test case file and directly performing automatic test according to a test case; a GUI module used for loading the calibration data and the automatic test case and controlling and executing calibration and test work; and a testing and calibrating module used for mutually transmitting data of the hardware-in-the-loop test system interface, the ASAM-3MC interface, the file read-write module and the GUI module.

Description

technical field [0001] The invention relates to the technical field of engine controller testing and calibration, more specifically, it relates to an INCA-based ECU software testing and calibration system. Background technique [0002] There are three main ways to test and calibrate existing engine controllers: [0003] 1. Most of the existing ECU calibration work is carried out by the calibration tool INCA, which is manually calibrated; ECU software testing is mostly carried out by hardware-in-the-loop systems and calibration tools, and the input or observed output signals are given by the hardware-in-the-loop system Calibrate ECU parameters or observe ECU signals through the calibration tool INCA, the entire test or calibration process is mostly done manually, and the efficiency is relatively low; [0004] 2. There are some automatic test tools in the existing market, but it is also necessary to write automatic test scripts before testing, and writing automatic test scrip...
