Using simulation to drive Toyota’s automated driving system development process
About
The Woven Planet Group was formed in January 2021 to expand and improve operations of Toyota Research Institute - Advanced Development (TRI-AD) for the purpose of developing innovative products that will enable its vision, “Mobility to Love, Safety to Live.” It also oversees Woven City, which will serve as an incubator for smart city design, connected mobility, and robotics technology from Toyota and its partners.

Goals
Woven Planet Group is at the forefront of automated driving vehicle development, incorporating the latest trends and technology into its development process. It focuses on developing algorithms that aim to deliver the world’s most secure, comfortable, and, above all, the safest mobility experience.
To accelerate the deployment of automated driving experiences in Toyota’s models, the team is focusing on the following key areas.
Automated driving control algorithm development
Develop algorithms capable of safely navigating through traffic-heavy highways.
Safety and functional safety testing
Ensure compliance with ISO 26262 etc., and that system/component failures are properly addressed.
Expanding coverage to test edge cases
Verify a perception module in various synthetic 3D environments that are difficult to reproduce on expressways and other motor-vehicle-only roadways.
A scalable approach
Test tens of thousands of scenarios concurrently to speed up the development cycle.

Approach
Woven Planet Group has partnered with Applied Intuition to test its self-driving system end-to-end under a vast number of scenarios quickly, safely, and comprehensively.
Automotive-grade simulation engine
Applied Intuition’s software is used in Woven Planet Group’s extensive testing process and informs Woven Planet Group’s development decisions.
End-to-end system testing
Applied Intuition’s simulation tools enable the end-to-end verification of complex systems, including the perception module. Continuous integration (CI) environments of such systems are also created.
Seamless integration
Integration was customized to meet Woven Planet Group’s requirements (e.g., support for vehicle dynamics model integration).
Large-scale simulations in the cloud
An environment to test large-scale scenarios in the cloud in a parallel state was established.
Evaluation under a wide range of edge cases
Synthetic data enables the scalable generation and verification of situations by changing parameters such as weather, fog, time of day, and visibility.
Testing the perception module using synthetic data
Sensors such as Toyota’s proprietary cameras are modeled accurately; virtual 3D environments specific to Woven Planet Group’s operational design domains (ODDs) are generated procedurally to test Woven Planet Group’s perception stack without driving on roads.

Impact
Shorter development cycle
Woven Planet Group has gained abilities to build software in a virtual environment and test their system end-to-end, leading to a shorter development cycle.
High-quality software
Woven Planet Group can now develop high-quality software without re-work as a result of focusing on the CI environment and creating an environment that tests software regressions constantly.
Scalable comprehensive testing
Comprehensive tests are completed more quickly because simulations have scaled Woven Planet’s autonomous vehicle verification process.
