Advanced Methods for Calibration and Validation of Diesel-ECU Models Using Emission and Fuel Consumption Optimization and Prediction During Dynamic Warm Up Tests (EDC)

Modelling and Co-simulation of hybrid vehicles: A thermal management perspective

“…Historically, vehicle powertrain models would consistent of relatively simplistic models (e.g., mapped engines [73]) so that they can be quickly created, parameterized, validated and simulated in a variety of configurations for component sizing and control optimisation exercises [74][75][76]. However, dynamic characteristics of the engine response have become much more important due to the events such as engine and transmission warm-up [53,77,78], engine stop-start [79,80], tipin [81], and power-on gearshifts occurring more frequently during the tests. These events can account for a substantial proportion of the emissions if not properly managed by the powertrain and vehicle supervisory control modules and therefore it is vital to include them in the vehicle powertrain model by using more advanced component models [78].…”
