It was only a couple of years ago that auto makers started appearing at CES touting self-driving car systems. Now those vehicles are taking to the roads in various trials around the world and on Wednesday in Las Vegas, we got a chance to ride in an autonomous version of Hyundai’s Ioniq four-door sedan.
The car was capable of “level 4” autonomy, which means it can drive itself without human help. It recognized traffic signals and stopped when needed, was able to negotiate turns and slow down for other traffic and pedestrians.
At the heart of the car are three laser imaging sensors that provide a 180 degree view of the surroundings ahead. The data from the sensors is matched with a detailed 3D map that was generated ahead of time, and enables the car to figure out where it is on the road. It also picks up on visual cues like lane markings.
