Teammate Advanced Drive System Using Automated Driving Technology 2021-01-0068

Woven Core, Inc. has developed Teammate Advanced Drive, a driving support system with state-of-the-art automated driving technology based on the Mobility Teammate Concept by Toyota Motor Corporation. Teammate Advanced Drive enables intelligent Ramp to Ramp hands-off driving on highways. The system features a self-localization estimation system that uses an HD-Map (High Definition Map) and high-level redundancy across sensors, computing, actuators, power supplies, and data communication. The system also includes digital data uploading and downloading capabilities wirelessly OTA (Over the Air) in order to provide customers the latest map updates as well as new software features and upgraded performance. A number of characteristically unique sensors have been combined to monitor the entire perimeter of the vehicle with high reliability. The perception system combines sensing data from radars, newly developed LiDAR (Light Detection and Ranging), and cameras for redundant omnidirectional detection. Teammate Advanced Drive provides high-performance computing by combining multiple advanced SoC (System on Chip) and highly reliable MCU (Micro Controller Unit), in order to achieve real-time execution of multi-processing system components, including deep neural networks. In order to provide enhanced safety, a fail-safe operation system, which utilizes a high-redundancy structure, has been developed to takeover for the driver when a malfunction or a system limitation is detected. This includes an Emergency Driving Stop System, which is able to guide the vehicle to the road shoulder if the system detects that the human driver is incapacitated or otherwise unable to drive the vehicle manually.
