ADAS (advanced driver-assistance system) systems are key for keeping drivers safe while also paving the way to autonomous vehicles. They use a variety of sensors to feed information about the environment to the car and protect the people inside it. Radar is one of those sensors and until recently, it worked by making a horizontal scan and looking for the “three Ds:”
● Doppler (relative velocity)
Aptiv, an Irish company, has developed a “4D” radar sensor. The main difference between the Aptiv sensor and a traditional one is that it also scans vertically. This is key in moving up the levels of autonomous driving and in keeping people safe. One example that Aptiv uses to explain the advantages of the sensor is that the sensor can detect whether a truck would be able to fit under a bridge when driving.
Auto Trendy’s take:
This sensor is certainly paving the path to the next level of autonomous driving. The main restrictor of having self-driving cars on the road is their safety. With innovations such as the one of Aptiv (and further advancements), we could see Level 5 autonomous cars starting to roll out in coming years.
