In a significant development in the world of autonomous driving, Audi subsidiary Autonomous Intelligent Driving (AID) has partnered with startup Aeva to bring its unique 4D lidar sensors to the company’s fleet of self-driving electric e-tron crossover vehicles. This collaboration marks a major milestone for Aeva, which has developed innovative lidar technology that measures distance and instant velocity without losing range or being affected by interference from other sensors or sunlight.
Aeva: The Startup Behind 4D Lidar
Founded just two years ago by Soroush Salehian and Mina Rezk, veterans of Apple and Nikon respectively, Aeva has made significant strides in the field of lidar technology. Their unique approach to lidar, dubbed "4D," allows for continuous low-power laser emissions that enable instant velocity measurements at cm/s precision up to 300 meters. This is a significant improvement over traditional lidar sensors, which rely on high-power pulses of light and can be affected by interference from other sensors or sunlight.
The Challenge of Lidar Interference
Lidar interference is a significant challenge in the field of autonomous driving. Traditional lidar sensors can be affected by interference patterns caused by pointing directly at the sun or having multiple sensors on the same vehicle. Autonomous vehicle developers often account for these issues by creating algorithms to reject outliers, but Aeva’s 4D lidar technology is designed to prevent these problems from occurring in the first place.
Audi’s Partnership with Aeva
AID CTO Alexandre Haag was impressed by Aeva’s sensors and their ability to provide long-range perception and instantaneous velocity measurements. After an 18-month validation process with Audi and parent company Volkswagen, Aeva’s sensors are now being used on Audi e-tron development vehicles in Munich. The partnership marks a significant milestone for Aida’s autonomous driving plans, which aim to bring urban mobility services online within the next few years.
The Benefits of Aeva’s 4D Lidar Technology
Aeva’s unique approach to lidar technology offers several benefits for autonomous vehicles operating in complex environments. By measuring distance and instant velocity without losing range or being affected by interference, Aeva’s sensors provide more accurate and reliable data. This is particularly important for vehicles operating in urban areas where pedestrians, bicycles, and other vehicles may be moving at different speeds.
Aeva’s Competitive Advantage
With the rise of lidar startups promising technological breakthroughs that can offer lower-cost sensors with better resolution and accuracy than Velodyne, Aeva’s unique approach to 4D lidar technology sets it apart from its competitors. By preventing interference patterns and providing continuous low-power laser emissions, Aeva’s sensors are designed for mass production and deployment on a large scale.
Audi’s Plans for Autonomous Urban Mobility
As Audi ramps up testing in Munich using its fleet of autonomous electric e-tron crossover vehicles, the company is making significant progress towards its goal of bringing urban mobility services online within the next few years. With Aeva’s 4D lidar technology on board, Audi is well-positioned to address the challenges of complex urban environments and provide safe and efficient transportation solutions for passengers.
Conclusion
The partnership between AID and Aeva marks a significant milestone in the development of autonomous driving technology. By leveraging Aeva’s innovative 4D lidar sensors, Audi is poised to make significant strides towards its goal of bringing urban mobility services online within the next few years. As the world continues to grapple with complex transportation challenges, companies like Aiva and Audi are leading the charge towards a safer and more efficient future for all.
