The Looming Lidar Revolution: Sub-$200 Sensors and the Future of Automotive Safety
For years, the high cost of lidar technology has been a major barrier to its widespread adoption in vehicles. Now, advancements in solid-state lidar are poised to dramatically lower prices, potentially bringing this crucial sensing technology within reach of mainstream automotive applications. MicroVision, a Washington-based sensor technology company, is leading the charge, aiming for production pricing below $200 per unit, and even targeting $100 in the long term.
The High Cost of Lidar: A Historical Perspective
Historically, lidar systems have been prohibitively expensive. In 2016 and 2017, mechanical lidar units used in autonomous vehicle research cost around $80,000 . These systems relied on spinning assemblies, making them complex and costly to manufacture. Over the past decade, prices have fallen significantly, with comparable mechanical lidars now selling for between $10,000 and $20,000. This price reduction has fueled optimism for further cost decreases.
Solid-State Lidar: A Game Changer
The key to unlocking lower prices lies in solid-state lidar technology. Unlike traditional mechanical systems,solid-state lidar uses phased array systems to steer laser beams,eliminating the need for moving parts. This simplifies manufacturing and improves reliability.MicroVision’s Movia S sensor is a prime exmaple, utilizing a 905-nanometer wavelength laser and offering a 180-degree field of view. While this is less than the 360-degree coverage of some mechanical systems, it can still detect objects up to 200 meters away under favorable conditions.
The Potential Impact on ADAS and Autonomous vehicles
Lowering the cost of lidar has significant implications for both advanced driver-assistance systems (ADAS) and fully autonomous vehicles. Currently, ADAS primarily relies on cameras and radar, which are cheaper but offer less precise 3D data. Lidar’s ability to create detailed 3D maps of the surrounding habitat can enhance safety and improve the performance of ADAS features like automatic emergency braking and lane keeping assist.
Hayder Radha, a professor of electrical and computer engineering at Michigan State university, notes that a reduction in cost of “one or two orders of magnitude” is feasible as demand expands beyond fully autonomous vehicles . This would allow lidar to become a more commonplace component in a wider range of vehicles.
Challenges and Considerations
While the prospect of sub-$200 lidar is exciting, challenges remain. Solid-state lidar typically has a smaller field of view than mechanical systems, requiring automakers to deploy multiple sensors around the vehicle to achieve full coverage.This adds complexity to the integration process,requiring precise alignment,calibration,and data synchronization.
Glen DeVos, CEO of MicroVision, emphasizes that automakers are designing complete perception systems, and cost is only one factor . the overall viability of the system is paramount.
Evaluating Lidar Performance beyond Cost
As lidar prices fall, it’s crucial to evaluate performance metrics beyond just cost. While cost reduction is significant, safety remains the primary objective of ADAS and autonomous systems. Researchers are using benchmarks like mean Average precision (mAP) to measure the accuracy of object detection and tracking,providing a more comprehensive assessment of lidar performance .
The Future of Lidar
Despite initial skepticism from figures like Elon Musk, who famously dismissed lidar as a “fool’s errand” in 2019 , the technology continues to evolve. Companies like MicroVision, Hesai, RoboSense, Luminar, and Velodyne are all actively pursuing cost-effective lidar solutions. If solid-state lidar can reliably achieve sub-$200 pricing, it could fundamentally alter the landscape of automotive safety, making advanced sensing technology accessible to a broader range of vehicles and drivers.
