Over the last few years, Advanced Driver Assistance Systems (ADAS) have seen incredible adoption as mounting evidence shows it provides significant improvements in road safety. At the end of 2020, 10% of vehicles in use worldwide were equipped with ADAS, and it is projected that over half of all vehicles will have ADAS safety features by 2050.
From an article in Wards Auto by Hesai.
ADAS is already reducing the number and severity of crashes by minimizing the effects of human error. According to the National Highway Traffic Safety Administration, human error contributes to 94% of all automobile crashes. As a solution to this issue, one study found that ADAS vehicles showed a 27% reduction in the frequency of bodily injury claims and a 19% reduction in property damage frequency.2 Another study estimated that ADAS for vehicle safety could prevent approximately 40% of all passenger-vehicle crashes and 29% of all deaths in crashes that involve passenger vehicles.
Light detection and ranging, or lidar, is becoming a key component in new ADAS technologies designed to further improve safety features. Lidar sensors use infrared laser light to accurately measure distances and create 3D maps of a vehicle’s surroundings, locating and recognizing vehicles, people, and objects that could affect driving.
Compared to other sensors such as traditional cameras and radar, lidar sensors can capture the most accurate information about the size, shape, location, and movements of surrounding objects. Unlike cameras which only receive visible light, lidar actively emits laser light into its surroundings, making it effective even in dark, bright, and other challenging lighting environments. Lidar can also obtain depth information directly, providing consistent perception in tricky situations such as black vehicles in dark settings or white objects against a white sky or background. On top of that, lidar has been shown to integrate well with other sensors, such as cameras and radar, to create safer and more effective systems.
As lidar sensors continue to integrate with ADAS, forecasters now predict that the global automotive lidar market will remain at an impressive 69% CAGR between 2022 and 2028 for passenger cars.
