ADAS, or Advanced Driver Assistance Systems, describe levels of safety as defined by the Society of Automotive Engineers (SAE) as Levels 1-4. Within these levels, systems are designed to add progressive collision avoidance and safety features to vehicles. Levels 1-2 systems are mostly passive with monitoring and alerts, and limited automation, including Back-up Assist, Parking Assist, and Cruise Control. Automatic Emergency Braking and Full Automation under 35 MPH are ADAS at Levels 3-4. They require powerful Lidar-centric safety systems. Traffic Jam Assist, Lane Change Assist, Keeping Assist, and Turning Assistant are all use cases that need a view of 360 degrees at range both day and night for true safety.
Achieving safe driverless vehicles is one of the great technological ambitions of our time. Fully autonomous vehicles include computer vision, advanced control systems, and sensing technologies that will allow vehicles to navigate without any human intervention. Lidar is the foundational component for driverless vehicles, as it is the 3D, 360-degree, long-range and self-illuminating vision system required for object recognition, collision avoidance, localization and mapping the surrounding environment to keep passengers and all roadway users safe. Driverless cars are held at the highest and most rigorous standards by the government in defining level 5 by the National Highway Traffic and Safety Administration (NHTSA) safety performance requirements for an autonomous vehicle.
