We’ve all experienced cars that warn us when we get close to an object when backing up or changing lanes. These driver-assisted technologies use radar in advanced driver assistance systems (ADAS) applications, such as collision warning and mitigation, and blind-spot monitoring. Analog Devices, Inc. (ADI) is proud that approximately 50% of all recently produced radar modules contain our technology.
While radar is central to the development of all-weather, autonomous driving, if cars are to truly achieve greater decision-making abilities, more sensors are needed, such as cameras and lidar (light detection and ranging).
Today, our work in autonomous vehicle design includes investigating whether light can provide a sense of sight for the car itself. ADI’s breakthrough technologies use pulses of light through a car’s lidar, combined with radar, inertial sensing, cameras, and ultrasound, to enable a car to perceive and navigate the road. In an industry where safety to occupants, machinery, and cargo is of vital importance, ADI takes a strong stance on the need for fusion of multiple sensing modalities to provide redundancy. The use of lidar in addition to radar, cameras, and ultrasound provides an additional safety measure necessary for trusted and reliable vehicle operation.
The fully cognitive vehicle is one that is aware of both its current state and historical view (and nature) of its surroundings. Improving this intelligence, as well as its own state (position, speed, trajectory, and mechanical condition) will help create a safer, more intuitive autonomous driving experience. But, of course, all this rests on the sensor foundation, upon which everything else is built.
Who would have thought something as simple as a pulse of light could create such a positive technological impact on our daily lives?
ADI: On the Road to Autonomous Driving Vehicles
Perception sensors build a highly detailed view around vehicle, allowing the system to quickly, reliably detect/classify objects to act or warn for safer operation
Navigation solutions allow autonomous vehicles to operate in places where GPS signals can’t penetrate (e.g., tunnels) to provide an extra layer of safety
Power solutions drive to the highest efficiencies and lowest thermal design overhead
