Model based Real time Systems Engineering
Automotive manufacturers face enormous pressure to increase the range of vehicles/technologies that they offer. In this competitive environment an y advances in simulation and virtual engineering offer significant advantages, especiall y when they reduce the amount of physical testing required. The Model Based Real time Systems Engineering (MORSE) project looks to push simulation based virtual engineering into new areas to help meet the challenge. MORSE is collaboration between Ford, AVL and Clayte x. The final system to come out of the project will consist of a Powertrain Control Module (PCM) model/hardware, sensor and actuator interfaces and vehicle network model provided by Fo rd, which will link to a HiL or SiL system running state of the art physical models of both th e engine and vehicle (developed by Claytex) AVL will then use their industry standard driveabil ity software (AVL Drive) to assess the vehicle performance. This real time system will then be use d to push the boundaries of virtual engineering to calibrate and validate both new engi ne diagnostic features and also to develop an automated process to calibrate driveability feature s that would normally require physical testing. In this paper we will introduce the technical appro ach taken in the MORSE project and present some initial results from both desktop based (SiL) tests and the real time HiL environment. The results presented demonstrate the potential impact of this project in terms of shifting product development efforts towards the virtual environment Keywords Combustion Engine Modelling, Driveline an d Transmission Modelling, Hardware in Loop testing, Performance Drivability.
