Toyota and Lexus are introducing their advanced active safety research vehicle at the 2013 Consumer Electronics Show in Las Vegas. The car features an array of sensors and automated control systems that could observe, process, and react to its environment. For this ability, the car is equipped with stereo cameras, GPS, radar and Light Detection and Ranging (LIDAR) laser tracking.
LIDAR consists of a 360-degree laser placed on the roof that could distinguish objects positioned around the car that are as far as 70 meters. The three HD color cameras could recognize objects that are about 150 meters away. Meanwhile, the radars placed on the front and sides of the car can measure the speed and location of objects.
On the rear wheel of the car is a distance measurement indicator to find out its speed and travel distance. To determine the car’s behavior, Toyota and Lexus attached an inertial measurements unit on the roof to measure changes in acceleration and angle. Furthermore, the GPS antennas installed on the roof could measure orientation and angle even before the car moves.
