Shashua says Mobileye may switch to house-built lidar sensors

Intel's silicon photonics manufacturing expertise will drive lidar costs low enough for consumer cars, says Mobileye CEO
The chief executive of Intel Corp-owned Mobileye on Tuesday laid out plans for a self-driving car system for 2025 that could use house-built lidar sensors rather than units from Luminar Technologies Inc and cost a "few thousand" dollars.
Luminar shares fell as much as 9% after Reuters reported the move. The company did not immediately respond to a request for comment.
Mobileye is making rapid progress toward a full autonomous driving system using cameras and a custom-made processor chip, but the company plans to augment its cameras with lidar and radar sensors that will capture a three-dimensional view of the road. Mobileye believes it can meet the safety and reliability requirements automakers are demanding for production vehicles by combining the two approaches.
Mobileye has deals to supply its current camera-based driver assistance systems to BMW, Volkswagen AG and Nissan Motor Co. Those systems help with tasks such as adaptive cruise control and lane-keeping and but also generate and transmit mapping data for Mobileye as they drive.
Amnon Shashua, CEO of Mobileye and an Intel senior vice president, told Reuters that data allowed the company's test vehicle to autonomously navigate the streets of Munich with only a week of setup and without flying any engineers from Mobileye headquarters in Israel to Germany.
"This is a critical milestone - this is what you need for scalability. If you want to have a system at the consumer level, it has to be able to drive everywhere," he told Reuters after the company posted footage of the successful test, which used a human safety driver as a backup.
Mobileye plans to demonstrate its camera-based systems with safety drivers in several more cities before rolling out a test fleet of 100 completely driverless vehicles augmented with lidar and radar in Tel Aviv in 2022.
In November, Mobileye said it had selected Luminar to supply lidar units starting in 2022. Luminar began trading as a public company earlier this month after a merger with Gores Metropoulos Inc, a special purpose acquisition company, or SPAC.
Shashua said the Luminar-based systems will cost between $10,000 and $20,000 and will be targeted at robo-taxis, which are commercial vehicles that can spread the cost of the system over many trips. But for 2025, Mobileye is developing its own lidar sensor that works on a principle called frequency modulated continuous wave, or FMCW, which is different from Luminar's technology.
Shashua said the FMCW technology will benefit from Intel's silicon photonics manufacturing expertise and will drive costs low enough for consumer cars. He said the house-built Mobileye lidar, in combination with cameras and radar, will be used on consumer vehicles and could also replace Luminar's units in Mobileye-powered robo-taxis.
"We believe the cost of an entire self-driving system can be in the few thousand dollar range, and that brings us into a consumer vehicle position," he said. "If we can make this work, it will also be used for robotaxis. But we have time to make that decision five years from today."
Mobileye does plan to continue outsourcing the manufacturing of its processor chips, Shashua said. He said the next generation of chip, called the EyeQ6 and expected to arrive in 2023, will continue to be made by Taiwan Semiconductor Manufacturing Co's using its 7-nanometer chipmaking process.
