Abstract
Facing the stringent constraints on fuel consumption and pollutant emissions, the automotive manufacturers have to produce vehicles with an increasing number of complex systems working together. Numerical simulation for the system design, set-up and control strategies, helps to reduce the development cycle and the global cost. Existing simulation tools usually do not address, with a high level of details, the various physical domains involved in a vehicle. To overcome this challenge, IFP, IMAGINE, IN-RETS and GAZ DE FRANCE settled a partnership to develop detailed simulation tools dedi-cated to performance, consumption and emissions for conventional and hybrid vehicles. These tools are integrated in a multi-domain simulation platform where several levels of de-tail can be easily reached for each sub-element. We present in the paper these simulation tools related to the vehicles, thermal engines (gaso-line, Diesel and NGV), exhaust line with the pollutant after treatment components and the electrical components (motor, battery). Application examples of complete vehicle models, including hybrid vehicles, with various levels of details are proposed with experimental vali-dation showing that architecture design, component development, control strategy, calibration and final validation can now be addressed with a single simulation environment.
