Automatic calibration simulation testing system for ECU stand

Abstract

The invention discloses an automatic calibration simulation testing system for an ECU stand. The system comprises an engine controller unit (ECU), calibration equipment ES590, a calibration PC (Personal Computer) machine for operating calibration software INCA and automatic calibration software ACME, a simulation testing system PC machine for operating simulation testing software HYVAT, PeakCAN / ValueCAN3USBCAN communication equipment, a simulation hardware platform and an electronic throttle valve, wherein the simulation hardware platform comprises one of an HY230 function test bed and a real-time simulation system HY360 capable of simulating various sensor signals required by the ECU and providing a simulation load for the ECU. Test cases are developed on the simulation testing system, so that logic test of automatic calibrated cases on the stand is realized, the automatic calibrated cases are sufficiently verified without occupying precious stand resources, and the calibration cost is reduced; and the automatic calibration simulation testing system can also be used for pre-calibration of the ECU stand, so as to shorten the real stand calibration time.

Description

technical field [0001] The invention relates to the intersection field of engine bench calibration and electronic control system simulation fields, in particular to an ECU bench automatic calibration simulation test system. Background technique [0002] The patent "Engine Bench Automatic Calibration System" (acceptance number: 20140321318.X) describes an engine bench test equipment, specifically, it involves a more convenient to use, which can greatly save manpower and time, and can realize all engine Engine bench automatic calibration system with automatic traversal of operating point. However, during the development and debugging of the automatic calibration case of the engine bench automatic calibration system, the resources of the bench are occupied, and the simulation test cannot be carried out to fully verify the automatic calibration case. The efficiency of automatic calibration depends on the maturity of the calibration process and cases. In the traditional calibrat...
