AUDI unit joins newcomer Ava for its unique lidar – TechCrunch

Audi's The Independent Driving Unit used startup with a unique approach to the leader while amplifying testing in Munich using the fleet of autonomous electric e-tron crossover vehicles.

The Autonomous Intelligent Driving company, or AID, said on Wednesday it uses sensor drivers developed by Aeva, which was established two years ago by veterans of Apple and Nickon.

SMF, a company from Mountain View, CA, launched by Soroush Salehian and Mina Rezk, has developed what it describes as a "4D lidar" that can measure distance, as well as instantaneous speed without loss of range, while preventing interference from the sun or other sensors, scroll in addition to 4D-branding speech, and technology is convincing.

Lidar, or radar for light detection and grading, measures distance. Many (with Tesla as one exception) consider that this is a key and necessary sensory automation in the process. For years, the industry is dominated by Velodyne.

There are dozens of startup laptops today that have come up with promises of technological discoveries that will offer cheaper sensors with better resolution and precision than Velodyne. This is a promise fulfilled by the challenges, especially the ability to increase production.

Traditional lense sensors can determine the distance by sending high power light impulses beyond the visible spectrum and then follow as much as necessary to return each of these impulses. As they return, the direction and distance to any impulse impact is recorded as a point and finally forms a 3D map.

Aeva sensors emit continuous low-power laser, which allows them to feel the instantaneous velocity of each point within range up to 300 meters, say the company. In other words, AI sensors can determine the distance and direction, as well as the speed of objects coming from or away from them.

This is a practical feature for autonomous vehicles working in the environment of objects traveling at different speeds, such as pedestrians, bicycles, and vehicles.

Ava, supported by investors, including Lux Capital and the Canadian partners, says that its sensors are also unique because they are "free" from the interference of other sensors or sunlight.

This combination of long-term observations, instantaneous speed measurements on cm / s of precision and robustness against disturbances was sold by AID CTO Alexandre Haag on Aeva sensors.

Aeva has spent the past 18 months through the validation process with Audi and its parent company Volkswagen. This announcement confirms that Aeva has passed the critical stumbling block in Aud's AV plans. The Aeva sensors are already on Audi e-tron development vehicles in Munich. The car manufacturer plans to bring autonomous driving to urban mobility services in the next few years.

Interference is possible and can cause accidental point current on the 3D map if the lid is directed directly to the sun or if there are more sensors on the same vehicle. Lidar companies have introduced various techniques to prevent interference patterns; Autonomous vehicle manufacturers also take into account potential problems of sun and snow disturbances by creating algorithms for rejection of such outliers.

Still, Salehian argues that interfering is a significant challenge.

When you talk about the challenge of building size and mass design, it's not just how easy it is to produce, says Salehian. – It's also about these things work together in a row. When you talk about hundreds of thousands of these cars, that's a big deal.
