Toyota has jumped into the autonomous car category, wondering with the rest of us if we will ever really get to buy cars that are so good at driving themselves that we can just sit back and read a book after punching our destination into the navigation system. Lexus is testing its technology on a tricked out Lexus LS460.
For now, Toyota and Lexus officials are stressing that, while this research could lead to fully-autonomous vehicles in the future, that's not really what they're going for. Instead, the company wants to focus on "partially automated technologies" that will enhance the skills of the driver.
Said Mark Templin, general manager of Lexus: "Our vision is a car equipped with an intelligent, always-attentive co-pilot whose skills contribute to safer driving."
The Lexus has been modified with multiple sensors, lasers, radars, and cameras for processing the car's surroundings. It has a 360-degree laser system on the roof that detects objects 70 meters away.
There are also three high-definition color cameras for detecting traffic light colors and approaching vehicles,. There is radar capability on the front and sides of the vehicle for measuring the location and speeds of nearby objects, and GPS antennas on the roof for estimating vehicle angle and orientation. The system also measures the vehicle's travel distance and speed, as well as acceleration and angle changes.
