Toyota is looking to refine its autonomous driving systems.

Toyota Research Institute (TRI), a subsidiary of Toyota Motor North America, has announced a new partnership with GoMentum Station that will aid the company's development of autonomous vehicle technologies.Per the terms of the agreement, GoMentum Station will give TRI access to its 5,000 acre autonomous vehicle proving grounds located in Concord, California. TRI will continue testing its autonomous wares on public roads, but the GoMentum Station facility will allow the firm to experiment with "extreme driving events that are unsafe to conduct on public roads."

Specifically, TRI will be testing its Guardian and Chauffeur driving modes. TRI's Guardian automated driving system still requires a driver at the wheel, but the system is always on-call to intervene in case of a potential crash situation. Chauffeur mode is fully autonomous and does not require a driver.

TRI test vehicles will be equipped with the company's latest Platform 2.1 technology, which includes new high-fidelity LIDAR that's longer range and able to collect more data. The new system will be put to the test around real-life infrastructure at the GoMentum Station facility, which includes roads, bridges, tunnels, intersections and parking lots.

"The addition of GoMentum Station to TRI's arsenal of automated vehicle test locations allows us to create hazardous driving scenarios for advancing capabilities of both Guardian and Chauffeur and further develop our technology," said Ryan Eustice, TRI vice president of autonomous driving.

Toyota is hoping to have its first autonomous car on the road by 2020.
