The cameras Tesla relies on almost exclusively can struggle in darkness, poor weather or blinding light, especially when trying to make sense of broad surfaces, noted Matthew Weed, Ph.D, an optical scientist, engineer and product director at Luminar. The camera works in conjunction with a cabin-focused onboard radar capable of detecting the breathing of occupants, from a strapped-in infant to a slumbering pet, to ensure nobody is accidentally left behind.Įlon Musk has been lidar’s most-famous skeptic, branding it as a “crutch” and a “fool’s errand.” But Musk now stands nearly alone among automakers and automated-driving tech experts who see a profusion of redundant onboard sensors as a good thing.

It uses artificial intelligence (AI) that can detect not only driver inattention, but also driver intoxication or medical impairment. It’s part of 30-sensor array - including 16 ultrasonic sensors, five radars and eight cameras - to deliver 360-degree views around the electric SUV.Ī camera in the EX90’s interior handles driver monitoring. The lidar itself has a 120° field of view (FoV) and a 26° dynamic vertical FoV. Iris scans a vehicle’s surroundings in real time, firing millions of laser pulses to create a virtual 3D map, with no need for GPS or a cellular connection. The Iris uses pulsed, time of flight (ToF) target illumination that Luminar engineers claim delivers an exceptionally fast measurement rate, an immediate understanding of reflectance, and no speed-dependent range error. Claimed resolution is greater than 300 points per square degree. The lidar’s receiver uses indium gallium arsenide (InGaAs) microchip technology rather than silicon.
more typical 905-nm shorter-wavelength lasers) being harmless to the human eye. Iris’s light source is a 1550-nm fiber laser, the longer wavelength (vs. Known as Iris, the full-stack system is considered semi-solid-state, its scanning mode using larger ‘macro’ scanning mirrors rather than MEMS’ micro mirrors. The system’s linchpin is the first rooftop-mounted lidar unit on an international-market passenger vehicle, developed by the Florida-based Luminar. To that end, Volvo executives said their flagship EX90 will go on sale in 2024 with all the hardware required for fully unsupervised (SAE Level 4) driving. The space in-between is a potentially unsafe limbo, at least for now. To Volvo, driving will be either supervised or unsupervised.

With safety as its brand-defining hallmark, the Swedish OEM threw down a gantlet at the Stockholm unveiling of its electric EX90 SUV: In Volvo’s contrarian view, there is no need to pursue hands-free Level 2 systems such as GM’s Super Cruise, which still expect drivers to watch the road and retake control at a moment’s notice. And with everyone from General Motors to Mercedes-Benz struggling to leap beyond SAE-defined Level 2 driver-assistance, Volvo has apparently had enough. Tesla and other automakers also continue a public spat over the best technical or social solutions. federal investigation of its Autopilot system. We see the lidar as a symbol of 21st century automotive safety, like our three-point seatbelt was in the 20th century.”Ĭonsumer skepticism over autonomous vehicles is running rampant, thanks largely to Tesla’s broken-record promises to make “Full Self Driving” a reality - along with high-profile accidents, fatalities, and a U.S.
