Toyota makes mixed reality magic with Unity and Microsoft HoloLens 2

Learn how Unity and HoloLens 2 have become essential tools one of the world’s largest automakers to streamline processes, increase understanding, and save time.

One of the core principles of Toyota Motor Corporation is Kaizen (continuous improvement). In both production equipment and work procedures, Kaizen seeks to drive maximum quality, efficiency gains, and elimination of waste.

Toyota often turns to technology to deliver these improvements, which is why the automaker was an early adopter of 3D data for digital engineering and later embraced real-time 3D technology. Toyota uses Unity’s real-time 3D development platform in many ways across its automotive lifecycle.

Its virtual pipeline starts by importing vehicle data into Unity using Pixyz. This process quickly converts Toyota’s large computer-aided design (CAD) assemblies into lightweight content suitable for real-time 3D. 

The company then uses Unity to develop applications tailored to its needs and deploy them to various platforms, whether it’s conducting training sessions in virtual reality (VR), creating stunningly realistic car configurators for its luxury Lexus brand, or condensing inspection workflows from days to hours with HoloLens.

Driving continuous improvement with HoloLens 2 and Unity

Toyota has used Unity to create and deploy mixed reality applications to Microsoft’s revolutionary device across its automotive production process. Naturally, its team was eager to expand their mixed reality capabilities with HoloLens 2, the next generation of Microsoft’s wearable holographic computer. 

Watch the talk below from Koichi Kayano, the project leader of mixed reality for automotive digital engineering at Toyota, which introduces several proof of concept cases in progress. Learn how Unity and Microsoft’s new mixed reality devices are helping Toyota achieve Kaizen in several aspects of design, manufacturing, and field service.

Here are some of the many ways Toyota is saving time, reducing costs and driving efficiencies with mixed reality.

Improving design reviews for computational fluid dynamics (CFD) analysis

Previously an arduous task, CFD analysis is now made simpler with the assistance of mixed reality. Toyota uses Unity and HoloLens 2 to capture and display CFD analysis on a vehicle in real-time to streamline the design review process.

Going around a stationary vehicle, the user can simulate and analyze how its design affects aerodynamics. And using multiple HoloLens 2 devices, Toyota’s team can share their view with one another to better communicate and collaborate during a review process.

Once a vehicle is assembled, it is challenging to explain the functionality of hidden mechanisms within the vehicle. This is made more difficult when the function requires the vehicle to be in motion. 

Using HoloLens 2 and Unity, users can now move around and inspect the inner workings of a “moving” vehicle – making a task that was once impossible now able to be easily and safely performed.
