Model based Vehicle Energy Management and Driveability

Under pressure from legislation as well as customer buying behavior, automotive OEMs and suppliers are currently devising solutions to improve CO2 and emission levels as well as fuel economy. However, consumers want it all: improved fuel economy and cars that are fun to drive as well as safe and ever cheaper. Translated to vehicle engineering targets, this means that seemingly conflicting engineering challenges need to be reconciled to manufacture the cars that will determine the world’s future mobility. And time is essential: being early on the market is a major success factor. We propose to present how a model-based vehicle energy management approach can remedies the problem of integrating green engineering into the current development process while continuing to improve the car’s drivability and performance. A first vehicle energy management simulator including most thermal subsystems is detailed into the paper “CO2 reduction by optimization of the Vehicle Thermal Management: a Multi-Domain System Simulation approach”. The benefit of such simulator is illustrated on engineering analysis aiming to investigate design changes on the heat management strategies or architecture and the corresponding gain on fuel consumption and emission. A second level simulator, which is the purpose of the present paper, including actuator dynamics and detailed representation of the transmission will illustrate trade-off balancing studies between vehicle drivability and fuel economy. The optimization of gear shifting control algorithms including a HiL simulation will illustrate how we can help you to reduce development time almost in half and create transmission designs that exactly meet target performance requirements.
