LIDAR stands for Light Detection and Ranging, senses what’s around a vehicle by sending out thousands of laser pulses every second. When those pulses hit an object, they reflect onto the LIDAR system, enabling it to gather precise three-dimensional information about other vehicles, terrain, buildings, and people, including their shapes, movements, and speeds.
The technology has proven indispensable in creating driver-assistance features and fully self-driving cars. Automakers like Nissan and Stellantis hope to install LIDAR on their vehicles starting in the mid-2020s.
Imagine looking at your windshield to see an image of the road on the glass. In that image, you’ll see arrows from your navigation system telling you where to go. The names of nearby buildings may pop up if you’re looking for a particular company. And video-game elements such as speed limits, distance to destination, and amount of fuel may also appear.
That is the promise of augmented reality navigation. Mercedes-Benz has the beginnings of such a system that uses front-facing cameras to project the road on the windshield or dashboard screen. Expect increasingly sophisticated versions of this feature to appear on high-end models in the coming years.
Suppose you’re in danger of hitting another vehicle or person. In that case, Automatic Emergency Braking (AEB) autonomously engages braking to either slow down or stop your car before impact to minimize or prevent the collision. While more advanced systems use LIDAR to detect hazards, most depend on radar or external cameras.
