Validation Procedure for Worldwide Harmonized Light Vehicles Test Cycle via Hardware in the Loop - Real Time Testing

Abstract

This paper studies the behavior of a vehicle’s power-train model developed using IPG CarMaker software applications and connected to the testbed with IC Engine by Hardware in the Loop (HiL) real time testing methodology, for the homologation (due date 2017) driving cycle Worldwide Harmonized Light Vehicles Test Procedures (WLTP).The simulation task includes measuring the fuel consumption, power, and torque and pollutant emissions over the usual classical vehicle model for a WLTP driving cycle. Based on obtained results, a comparative analysis is performed for virtual vehicle model in IPG CarMaker and the real IC Engine on the testbed. Step-by-step simulation results are validated by integrating real-life data from on-board measurement via CAN Bus. The system captures various drivability related sensor and CAN bus signals. These input quantities were achieved from Puma Open testbed application and sent to be implemented on to the AVL InMotion equipment for further processing and analysis.
