  • The engine warm-up after a cold start depends not only on the engine, the driving cycle and on the vehicle itself, but also on the behavior of systems like cooling circuit and power train. The individual systems stand in interaction both with the engine as well as with the other systems. This requires for the simulation of the thermal management system that all relevant subsystems are simulated simultaneously and that the interaction between the individual systems is being considered in a correct way. Therefore, a generic simulation platform was developed. The main advantage of the platform is in being able to couple the simulation models without the need of special interfaces between the individual programs. Based on an example, the modeling of the individual subsystems of the vehicle is shown. For the verification of the single subsystems experimental measurements on a vehicle dynamometer have been performed. The comprehensive vehicle model is verified with the measurement data of a ‘real-world’ driving cycle. Key parameters such as coolant temperature, engine temperature, and cabin temperature are compared therefore. Based on an example, the modeling of the individual subsystems of the vehicle is shown.
