Why Use CarSim, TruckSim, or BikeSim?
CarSim,TruckSim and BikeSim provide system-level simulations of vehicles. They include enough detail to accurately reproduce vehicle tests for handling, braking, powertrain, etc., possibly with advanced electronic controllers.
The vehicle model is a "core" that has an easy-to-use GUI, detail needed to reproduce the vehicle response to driver controls on a 3D road surface, and an interface to other software that is often used to add advanced controllers or replace components with more detailed models.
The models run faster than real time, as needed to support optimization, sensitivity studies, and customized automated testing sequences. They can be slowed down to real-time to test hardware in the loop, or to power driving simulators.
