34 THE SHOP MARCH 2021 between a shopping cart and a human being. "The radar can see farther and wider than anything introduced before," says John Xin. "While radar does work in bad weather, today's radar sensors simply can't see in enough detail and have a limited field of view." This means that to have a Level 5 vehicle with today's technology it would take 16 to 20 radar sensors. Talk about complicated! Lunewave's goal is to reduce the number of sensors to a more manageable level—hope- fully two to four. THERMAL SENSORS Thermal sensors are important to autono- mous vehicles when radar and lidar can't work well, such as in a blizzard or intense fog, when going through a tunnel, when the sun's setting, during a severe downpour or even when driving on black ice. One new sensor company trying to help vehicles see in many different environments is AdaSky. Its technology is based on long- wave infrared (IR) sensors. "For a vehicle to be truly autonomous, it needs to have the ability to see in any range of conditions," says Ofer Livny, AdaSky VP of R&D. "Our sensors add the ability for vehicles to see in poor conditions. The unit can be installed inside the grille, inside the headlamps or on the roof in a shark fin-style antenna. The benefits are clear in pedestrian protection." The company's efforts coincide with the Vision Zero initiative adopted by many municipalities across the country. "Thermal sensors will take ADAS to the next level," he believes. "They feature very low power consumption and there are no moving parts or shutters in our sensors. Instead, there is a chip inside our camera system that can analyze specific pixels and determine what they are. Thermal imaging will be integrated into the existing sensor suites, and we hope the government will get involved and mandate this technology to help save lives." The company reports that units could be in vehicles as early as 2024, with possible aftermarket applications to follow. "We have looked into aftermarket instal- lation with a heads-up display, but we want to make sure it doesn't become a nuisance to the driver or create unwanted driver distraction," Livny says. KEEPING SENSORS CLEAN Lidar, which works on the principle of radar but uses light from a laser, may also play a big role in the future of safe autono- mous vehicle travel. Tom Jellicoe is an auto industry tech- nical consultant for British firm TTP. A University of Cambridge graduate with a PhD in physics specializing in optics, he and his team are pursuing cleaning tech- nology using ultrasonic waves to keep sen- sors working in all conditions. "Lidar is complex. It will take a lot to get it right," Jellicoe predicts. "The OEMs are looking for a lidar sensor that survives on the exterior of a car for 10 years, operates AdaSky technology is based on long-wave infrared sensors to help vehicles "see" in many different environments. Seeing the Future Worldwide ADAS Market Could Reach $72.9 Billion by 2026 As Advanced Driver-Assistance Sys- tems become standard equipment in new vehicles around the globe, a comprehensive overview by UnivDatos Market Insights predicts the world- wide ADAS market will grow at a com- pound annual growth rate of 15.9% from 2021-'26 to reach $72.9 billion. By System Type, the report seg- ments the market into: • Adaptive Cruise Control (ACC) • Adaptive Front Light (AFL) • Automatic Emergency Braking (AEB) • Blind Spot Detection (BSD) • Drowsiness Monitor System (DMS) • Intelligent Park Assist (IPA) • Lane Departure Warning (LDW) • Other ADAS Systems Intelligent park assist is predicted to dominate the System Type segment at 13.5% CAGR to reach $17.3 billion by 2026, according to the report. The various Sensor Types include: • Image Sensor • Lidar Sensor • Radar Sensor • Ultrasonic Sensor • Other ADAS Sensors Image sensors account for the largest share in the report, with growth predicted at 14.1% CAGR during the next five years. In 2019, the image sensor segment accounted for a rev- enue share of almost 35.9%. By Vehicle Type, the market includes: • Passenger Vehicles • Light Commercial Vehicle • Heavy Commercial Vehicle In 2019, the Passenger Vehicles segment dominated the global ADAS market with nearly 52.8% market share and is predicted to reach $39.6 billion by 2026.
