DEVICE FOR INSPECTING THE PERFORMANCE OF AN ACTIVE TYPE AIR SUSPENSION SYSTEM IN INDOORS BASED ON A HILS SYSTEM FOR A COMMERCIAL VEHICLE

摘要

PURPOSE: A device for inspecting the performance of an active type air suspension system based on a HILS(Hardware-In-The-Loop Simulation) system for a commercial vehicle is provided to easily and economically inspect an air suspension system with an inspecting device based on a HILS system in a laboratory without actually installing the air suspension system on a vehicle.;CONSTITUTION: A device for inspecting the performance of an active type air suspension system based on a HILS system for a commercial vehicle comprises a host computer(110), a HILS system(120), a test bench(130), and an ECU(Electronic Control Unit)(140). The host computer outputs models of an engine and a vehicle and data calculated on a real time basis and a common program capable of simulating a real-time vehicle movement is mounted on the host computer. The HILS system is composed of a plurality of target computers and transmits a result obtained by analyzing a dynamic analysis and calculation of the vehicle driven by the ECU and an electronic system of the vehicle to the host computer. A motion module is mounted on the test bench. The ECU controls the air suspension system.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Host computer; (120) HILS system; (121) Target computer 1; (122) Target computer 2; (123) Target computer 3; (130) Test bench; (140) Air suspension system ECU; (150) Solenoid valve module; (160) Servo motor accumulator; (AA) Dashboard(I.C); (BB) Manipulating a dashboard S/W; (CC) Remote controller; (DD) Garage sensor; (EE) Monitoring board; (FF) Connector
