Video: Watch Nvidia’s self-driving car technology in action

27 August 2019

Nvidia Corp. has released a new video depicting tests of its Drive Constellation platform and operating test cars on public roads nears its headquarters in Santa Clara, California.

In the video, safety drivers remain at the wheel, monitoring the system and various software. The company is testing its perception building block algorithms, which are mathematical models inspired by the human brain that learn by experience. The DriveNet DNN technology enables a data-driven understanding of obstacles while computing the distance to these obstacles. LaneNet is a technology that helps with lane detection and perceives navigable paths.

Other technology being tested includes WaitNet, LightNet and SignNet that detect and classify wait conditions such as at intersections, traffic lights and traffic signs.

The system anaylzes high-definition map information, route information and real-time localization results to create an origin-to-destination lane plan for its target route. The system provides information when a self-driving car needs to stay in a lane, change lanes or negotiate traffic movements along the route. This technology also tracks vehicle location and estimated time-of-arrival.

The Nvidia Drive AGX platform runs all of these components in the vehicle, enabling 360° surround perception, localization and planning, and control software in real time, the company said.

Thank you for that level of detail in your self-driving video. I hope there will be more to come. I would love to see a birds-eye view that depicts the decision process when maneuvering lane changes in heavier traffic. Will the self-driving system be more aggressive to ensure it makes the lane change, or less aggressive to avoid risk at the expense of missing an off ramp? Lots of great challenges.

Can't we spend our money and use our technologies for something useful. iF YOU WANT TO SIT IN A VEHICLE AND NOT BE IN CONTROL OF IT, TAKE THE BUS.
