In system and vehicle development, it is essential to simulate the physical system properties at an early stage in each of the different phases of the development process. This is required to evaluate, improve, and safeguard the designs.
For example, the motor dynamics, drive dynamics, vibration comfort, durability, and behaviors of assistance and safety systems must be calculated. Additionally, different complexities of the model and computational speeds are required for the various tasks and the different phases. Increasingly important is the possibility of hybrid and interactive simulation to integrate the electronic controls and the driver realistically into the computations.
