System Modeling and Simulation Sub-Team
The System Modeling and Simulation Sub-Team creates mathematical models for the various vehicle components and runs the models through various simulations in order to test their performance and to optimize the teams control strategy.On year three, System Modeling and Simulation subteam will finish and improve their own modellings on ESS, Electrical motor and Vehicle Dynamics. The subteam will also extract new drive circles when the car has all the new parts integrates to work again with Autonomie having more realistic results.

During year two the System Modeling and Simulations subteam started working with Hardware-in-the-Loop (HIL) and develop Ecocar3 own models such as plant and softECU models. Instead of working on purely Software-in-the-Loop (SIL) simulation the subteam is developing test cases using both SIL and HIL, which accurately reflects real vehicle operation. The subteam also expanded the tests coverage to include safety critical components and simulates situation changes, for example temperature increasing when torque increases.
System Modeling and Simulation subteam works in cooperation with other engineering subteams. They are responsible for testing a components parameters and plant models using different softwares.
During year one the subteam worked with Autonomie and SoftECUs. Those softwares use a virtual vehicle to evaluate the impact of different components technologies, analyze the effects of powertrain design, and help to create control strategies on vehicle energy consumption, fuel economy, emissions and others. The simulations helped the Cal State LA Ecocar on defining which would be the best engine, electric motor, battery pack, fuel tank size and type of fuel, transmissions, and others parameters and components.
