Nvidia looks to the AI future An interview with Nvidia CEO Jensen Huang
Nvidia Corp has temporarily suspended self-driving tests across the globe, a source told Reuters at the GPU conference in San Jose, California, a week after an UberTechnologies Inc [UBER.UL] self-driving auto hit and killed a woman crossing the street.
The chipmaker is testing self-driving technology globally including in New Jersey, Santa Clara, Japan and Germany. The decision comes on the heels of news last week that a pedestrian hit by one of Uber Technology Inc.'s autonomous vehicles died in Arizona, marking the first fatal accident involving self-driving vehicles.
Nvidia's announcements come at a pivotal time for the self-driving vehicle industry. "DRIVE Constellation for virtually testing and validating will bring us a step closer to the production of self-driving cars". "It's a reminder of how hard [self-driving car] technology is and that it needs to be approached with extreme caution and the best safety technologies", Nvidia said in a statement.
The system is based on two servers with one simulating the vehicle's sensors and the other the vehicle's software that processes the simulation data.
Driving commands from DRIVE Pegasus are fed back to the simulator, completing the digital feedback loop. The second server contains the NVIDIA DRIVE Pegasus AI auto computer that runs the entire software stack in an autonomous driving vehicle.
"Deploying production self-driving cars requires a solution for testing and validating on billions of driving miles to achieve the safety and reliability needed for customers", says NVIDIA automotive vice president and general manager Rob Csongor.
Nvidia is helping autonomous vehicle manufacturers fit in more testing miles, faster.
The idea of self-driving cars is gaining a lot of traction these days, but the incident in Arizona may put the idea of autonomous cars on hold for a while.
The decision comes following the fatal Uber crash in Arizona, which may not have been caused by the self-driving technology, but still yielded some pause from other self-driving auto makers. The auto was in autonomous mode when it struck the victim, and it is the first known pedestrian death involving a self-driving vehicle. Waymo uses simulation in addition to physical testing.
