Toyota has released two videos showing the automaker's Mobility Teammate and Highway Teammate concept driver assist technologies. The first video describes how the new Mobility Teammate Concept technology can enhance commuting, while a Lexus GS sedan fitted with the Highway Teammate Concept demonstrates the benefits in the second video.

The automaker hopes its new driver assist technologies are ready for production by 2020. Toyota wants the human-machine interface to function like close friends with the driver and car working together for a common purpose.

A modified Lexus GS sedan is fitted with Toyota's Highway Teammate Concept. The system uses road map data along with external sensors including cameras, lidar, and millimeter wave radar to position the car safely in traffic. The on-board technology evaluates traffic conditions to determine the best action for various traffic situations including merging onto or exiting highways, maintaining or changing lanes, and maintaining inter-vehicle distances.

Based on the final destination, the system chooses the best route and lanes for the commute. The technology combines recognition and decision-making processes to automatically control the steering wheel, accelerator, and brakes, to safely navigate through traffic.
