Toyota Will Launch Self-driving Cars With Lexus Pre-Collision System Soon   

Toyota demonstrated its technology at foruth annual Advanced Toyota Safety Seminar in Ann Arbor Michigan. It hopes to put this technology on production cars by mid decade and it will increase further vehicles automation.

Among the technologies demonstrated was the latest version of Toyota's Automated Highway Driving Assist (ADHA), which was first unveiled in Japan last year. It combines dynamic radar-guided cruise control and a lane-following feature to allow cars to autonomously drive in traffic. This latest version was programmed based on actual U.S. traffic conditions, and can operate at speeds up to 70 mph.Toyota also demonstrated its new SPAD (Single Photon Avalanche Diode) lidar system. Lidar—a radar-like system that uses light instead of radio waves—is used in several prototype self-driving cars, but this version is more compact.
