![]() ![]() ![]() Current camera-based automatic emergency braking systems can typically only stop the vehicle in time at speeds up to about 25 mph. Longer detection ranges and higher resolutions combined with more sophisticated software running on a chip like the Orin allow the systems to make decisions earlier and potentially intervene before crashes happen. The Iris lidar is able to detect objects with 10% reflectivity at 250m which works out to about 8 seconds at 70 mph highway speeds. In this case, the vehicle will still be able to drive itself to a safe stop, something that may be more difficult or impossible with only one sensor type. This will help to enable fail operational capability during L4 mode if a failure of any one sensor type occurs. Unlike Tesla Autopilot and “Full Self-Driving” which now rely exclusively on cameras, the Sentinel system features redundancy and diversity with at least three types of sensors - cameras, radar and lidar. The combination of the more capable sensors including the lidar allows even lower level driver assistance systems to have increased situational awareness at longer distances. Nasdaq-listed Luminar booked orders potentially worth 1.3 billion at the end of 2020 in its first quarterly results report as a public company on Thursday. According to Russell, one of the goals in developing the Sentinel system with Zenseact was a focus on proactive safety. Since the full sensor suite including the Luminar Iris, radar and cameras as well as a driving computer powered by an Nvidia Orin processor are designed into the SPA2 platform, follow-on models in the 90 and 60 series will likely include this hardware as well. Something like a level 2 system similar to GM Super Cruise but more capable than Volvo’s current Pilot Assist will likely be the standard offering. The fully automated highway driving software won’t be standard at first, it will be an extra cost upgrade delivered by over-the-air update. Tesla has not done that with its self-proclaimed full self-driving and says drivers remain responsible for the operation of the vehicle. However, Volvo is the only automaker so far to publicly state that when its vehicles are being used in highly automated mode, it will take full liability for anything that might go wrong with the system. One big question that remains unanswered at this point is exactly where people will be able to use L4 capability on the XC90 since the regulatory landscape is still very much undefined. Full details of the operational limits of the system or how transitions will be handled aren’t being revealed yet. Unlike other level 2 or level 3 systems, it will not require any supervision from the drive while being used. On the XC90 it will offer completely hands-off, eyes-off, brain-off operation on the highway. The system was co-developed by Luminar and Volvo subsidiary Zenseact and will be available later on vehicles from other manufacturers including China’s SAIC. SAIC, China’s biggest automaker, has said it will use Luminar for its electric R brand cars.What may be a first for Volvo is offering a system that consumers can purchase with level 4 automated driving capability. Luminar also has a production deal with Volvo Car AB, which plans to incorporate a lidar-based safety system on its electric XC90 SUV coming out this year. Laser sensors also can improve the performance of existing safety features such as automatic emergency braking, Luminar says. Most self-driving tech developers consider lidar, which bounces lasers off objects to enable a vehicle to “see” its surroundings, a critical safety layer that helps cars pilot themselves on highways, freeing up drivers to check email or watch a movie. “Luminar is the perfect addition to our existing roster of first-class cooperations with leading and cutting–edge tech companies.” - Markus Schäfer /S7kpjBAVwu- Luminar January 20, 2022 Luminar and partner to enhance safety and autonomy on next-gen Mercedes-Benz passenger cars. Mercedes also is taking an unspecified minority stake in the Orlando, Fla.-based lidar manufacturer, Luminar said Jan. ![]()
