Lidar is becoming a tool that is frequently being used in vehicles. While once thought of as something that would find a use mostly in autonomous driving, lidar has already found a home in advanced driver assistance systems (ADAS), which is a growing feature on almost all automobiles — gas or electric.
And it isn’t just on the luxury side of vehicles either, even budget friendly vehicles are getting the ADAS treatment like forward collision warnings, adaptative cruise control, emergency braking, high beam assist and lane departure warnings.
As technology improves and the cost of lidar and other electronic systems falls, more ADAS features will continue to find their way into vehicles.
This year, Hesai rolled out its ATX lidar, a low-cost basic unit that can be integrated into many vehicles due to its price point.
The following is a partial deep dive into the Hesai ATX lidar conducted by TechInsights.
