- Summary:
- Fuel economy has become a key challenge for Automotive engineers due to the increasing fuel prices and efficiency standards. System level simulation is vital in assessing the vehicle performance and fuel economy at an early stage of product development life cycle. A workflow for powertrain simulation is established and the relation between calibrations and fuel economy is analysed. A map-based engine is modelled using the engine performance data obtained from engine dynamometer test bench setup. Design of experiments (DOE) is carried out on the measured data with an objective of minimizing fuel consumption or maximizing brake power to arrive at an optimized set of data. Exhaust temperature and knock limit are set as constraints for the DOE study. A full vehicle model is developed with the optimized map-based engine along with transmission, chassis and driver model. Desired drive cycle (WMTC) is used as target velocity profile to the driver model along with a neutral gear selection strategy. Starter and idle speed control logics are included in the engine control module. The full vehicle model consists of manual transmission along with clutch dynamics followed by the vehicle body and tyre models. It is observed that with an optimized engine performance data the vehicle mileage is improved along with the acceleration performance. The optimized engine map data is provided to the calibration team to develop a prototype engine model during the design phase. MATLAB, Simulink and other add-on products have been used as the platform to perform the virtual calibration studies
