At the company's annual GTC Summit in San Jose, California, Nvidia founder and CEO Jensen Huang announced a two-server solution that simulates data generated by a self-driving auto and trains a driving algorithm using that data. Autonomous-driving companies have also been using simulators built for gaming to train their algorithms.

Unsafe situations can be scripted in simulation to test the autonomous car's ability to react, without ever putting anyone in harm's way.

Nvidia Corporation (NASDAQ:NVDA) announced that it would be halting its self-driving vehicle tests for a moment in order to ensure the safety of people on the road. Nvidia will suspend its autonomous vehicle testing in public roads for a limited time.

The goal, they say, is to create a safer and more scalable method for bringing self-driving cars to the roads - welcome news for many considering the recent pedestrian death that shut down Uber's operation. We are temporarily suspending the testing of our self-driving cars on public roads to learn from the Uber incident.

One of the servers in Nvidia's new Drive Constellation Simulation System, powered by the company's GPUs, runs Nvidia-developed Drive Sim software, which simulates cameras, LIDAR, RADAR - sensors a self-driving vehicle uses to observe its physical environment.

Investigative journalist Sandeep Sharma mowed down by truck in MP's Bhind district
Navin Nishchal, who worked for Dainik Bhaskar, and his colleague Vijay Singh were on a bike when they were hit by a auto . Bhopal Press Club president told the media that Sharma had informed the local administration about the issue.

The first server runs NVIDIA DRIVE Sim software to simulate a self-driving vehicle's sensors, such as cameras, lidar and radar.

This "hardware-in-the-loop" cycle, which occurs 30 times a second, is used to validate that algorithms and software running on Pegasus are operating the simulated vehicle correctly.

In the same time, the software was put through 2.7 billion miles of testing in a virtual world, allowing algorithms to be quickly refined and tested against numerous variations of certain tricky real-world or hypothetical scenarios. The on-demand vehicle pooling company is just one of many tech giants that uses Nvidia's computing platform to power its fleet of self-driving cars.

"This means you can easily test rare and hard conditions: rainstorms, snowstorms, and sharp glare at different times of the day and night, with different road surfaces and surroundings", the company says.

Huang said DRIVE Constellation with be available in the third quarter of this year.
