  • In the 1950s and 1960s, basic mathematical models were used to study vehicle dynamics.
  • Engineers relied on equations to simulate basic motion, handling, and stability.
  • These early models were limited and lacked real-time interactivity.

2. The Rise of Computer-Based Simulations

  • In the 1970s, computers allowed more complex simulations.
  • Researchers developed software to simulate braking, steering, and suspension behavior.
  • Simulations became essential for automotive design and crash testing.

The Shift to Real-Time Simulation

3. Driving Simulators for Training

  • By the 1980s and 1990s, vehicle simulators were widely used for driver training.
  • Flight and military vehicle simulators set the standard for high-fidelity systems.
  • Simulated driving environments helped train new drivers without real-world risks.

4. Hardware-in-the-Loop (HIL) Technology

  • The 1990s introduced Hardware-in-the-Loop (HIL) simulation.
  • Engineers could test real vehicle components with virtual environments.
  • HIL technology improved automotive safety and performance testing.
