Mechanical Simulation Corp.’s CarSim 9.0 vehicle dynamics software upgrade features major enhancements to the math models, visualization tools, database, and overall architecture. In version 9, CarSim makes it even easier to simulate tests used by automotive manufacturers and suppliers to evaluate performance of vehicles that don’t yet exist or to cover conditions that are difficult or too dangerous to handle with physical testing, claims the company. Suppliers use CarSim as a vehicle platform for testing advanced controllers developed with other software, such as MathWorks’ Simulink. Some of the changes in CarSim 9 are evolutionary, such as extending the tire model to handle asymmetric data or increasing the number of add-on features, such as sensors, payloads, etc. Other parts of the software package were modified extensively or replaced completely.
