Lidar sensors generate a 3D map of the world around the car. In addition to the map, Aeva’s sensor detects the velocity of objects in a car’s surroundings, which could help cars determine whether an object hundreds of meters down the road is a tree or a pedestrian.
Aeva’s sensor uses a different technology than other lidar units currently being tested on the road, which have spinning parts and send out powerful laser bursts. Aeva’s sensor has no moving parts and uses a less powerful continuous wave. That allowed the company to put the most important parts onto a chip about the size of a U.S. quarter that can be made in the same factories that currently make data center networking chips.
Aeva believes it can sell sensors for less than $500 that can see 300 meters ahead. Early next year, Aeva plans to release a unit that is half the size of its predecessor but with a field of view which is twice as wide at 120 degrees. It aims to release a smaller, final production version by 2022.
