Driving simulation has undergone significant advancements, and one of the most notable breakthroughs in recent years has been the integration of virtual reality (VR) and more recently the Mixed Reality (MR) in the automotive simulation industry. This integration has opened countless opportunities for research and industry professionals, who combine the power of VR/MR to create an unparalleled level of realism and immersion to test mobility systems in virtual conditions.

Benefits of Using Virtual Reality for Automotive simulation

There are several reasons why virtual reality has gained significant importance in the field of automotive simulation. One of the major reasons is the ability to collect precise data on vehicle and driver performance. In the automotive industry, data plays a crucial role in understanding and improving vehicle design, performance, and safety. By harnessing virtual reality, engineers and researchers can collect data that provides valuable insights for evaluation and optimization purposes.

Moreover, virtual reality offers a safe and cost-effective alternative to real-world road tests. Physical driving tests can be time-consuming, expensive, and potentially risky. With virtual reality, engineers and researchers can simulate a wide range of driving conditions and scenarios, including extreme or hazardous situations, without endangering individuals or vehicles. This not only enhances safety but also significantly reduces costs associated with real-road testing.

Developers have been constantly working on techniques to enhance the virtual reality experience in automotive simulation. This includes advances in graphics rendering, offering 4K rendering for more natural interaction with virtual environments. They have also made technical improvements using VR controllers, simulation steering wheels, pedals, or even VR gloves, for a more realistic feel, as well as immersive sound effects integrated into it.

Additionally, virtual reality allows engineers to experiment with innovative ideas and concepts in a virtual environment. By creating virtual prototypes and conducting simulations, they can explore new designs, evaluate different technologies, and measure their impact on vehicle performance. This iterative process enables faster innovation and shorter iteration cycles, leading to improved designs and more efficient development processes.

To resume, The use of virtual reality (VR) brings several significant benefits to driving tests: 

  • Realistic immersion: Virtual reality-based driving simulators provide a high level of immersion, allowing users to experience authentic driving scenarios.
  • High-resolution VR headsets: The use of high-resolution VR headsets enhances the visual experience, making the simulation more realistic and engaging.
  • Advanced simulation platforms: The integration of advanced simulation platforms enables engineers and researchers to create a controlled and repeatable environment for testing and optimizing vehicle performance.
  • In-depth data analysis: The immersion provided by virtual reality facilitates in-depth data analysis, allowing for a thorough evaluation of vehicle and driver performance.
  • Innovation and problem-solving: Virtual reality-based simulators encourage the search for innovative solutions, helping engineers and researchers find new ways to improve vehicle performance.
  • Technological advancements: The use of virtual reality represents a significant step forward in technological advancements in the field of automotive simulation.

By using the benefits of virtual reality in automotive simulation, researchers and industry professionals can push the boundaries of virtual driving, improve vehicle designs, enhance safety, and stimulate innovation in the automotive industry. The integration of virtual reality and mixed reality technologies continues to revolutionize how mobility systems are tested, evaluated, and developed, paving the way for safer, more efficient, and technologically advanced vehicles on the roads.

Expansion of Mixed Reality in Automotive Simulation

Automotive simulation has recently evolved beyond Virtual Reality to include Mixed Reality, marking a significant milestone in the industry. This transition to mixed reality is driven by various factors, including the need to push the boundaries of immersion and create even more realistic simulation experiences.

Mixed reality combines real-world elements with virtual elements, offering new possibilities in the field of automotive simulation.

The advantages of mixed reality include:

  • Natural interaction: Drivers can interact with real-world objects and environments while benefiting from the advantages of virtual reality.
  • Information overlay: Drivers can see information such as speed, direction indicators, pedals, steering wheel, or gearbox directly overlaid on their real field of vision, enhancing interaction with the virtual environment.
  • Immersive learning environments: Students can interact with virtual and real elements, enhancing their driving experience and allowing practice of complex maneuvers.
  • In-depth understanding of the environment: The combination of mixed reality and virtual reality enables a better understanding and analysis of the perceptions offered by these technologies, facilitating skill acquisition and preparation for real driving situations.

A pioneer in Mixed reality in the automotive industry has been Volvo who has recently invested in the Finnish startup Varjo to support their engineers and developers to leverage the benefits of mixed reality in the vehicle development process, improving assessment accuracy, reducing costs, and accelerating innovation.

Challenges and Considerations in Integrating VR and MR in Automotive Simulation

Now, let’s explore the challenges and considerations that arise when integrating virtual reality (VR) and mixed reality (MR) in automotive simulation.

Virtual reality and mixed reality require advanced equipment like computer with a high-speed processor and a high-end graphics card capable of handling heavy loads, necessary to provide realistic driving simulation experiences. This can present challenges for companies in terms of costs and compatibility with existing systems.

Also, the development of accurate and realistic simulation models requires close collaboration between engineers and software developers to replicate various real-world driving situations (such as an entire city, for example), and to create complex and diverse driving scenarios. This may require significant efforts to gather data on traffic, roads, and driver behaviors to integrate them into virtual environments. It is also important to consider safety aspects when designing these scenarios to achieve the most realistic rendering possible which means a lot of time invested for a company.

If we look at all those aspects it is clear that, virtual reality and mixed reality have opened up exciting new possibilities in the automotive simulation industry.

With these technologies, engineers, students, and researchers can push the boundaries of virtual driving, benefiting from realistic immersion and interactive learning opportunities.

However, it is important to acknowledge and address certain limitations such as costs, complexity and planning.

By overcoming these challenges, the integration of virtual reality and mixed reality in automotive simulation offers substantial potential for the industry.

Close collaboration between industry stakeholders, researchers, and technology developers is and will continue to be crucial to address these challenges and pursue the development of advanced automotive simulation for the future of mobility systems.
