Google Patents Transition To Autonomous Driving For Cars


Google has just been granted a patent that describes a possible switch from a car that is driven by a human to an autonomous driving mode. The patent was written by a group of engineers that includes the winners of the 2007 DARPA Urban Challenge.

We have heard quite a bit about Google’s autonomous cars driving around in California. A patent approved by the USPTO yesterday provides more detail on these cars and the technology they may use. The patent #8,078,349, filed on May 11 of this year, specifically refers to the event when a mixed-mode car is enabled to transition from a human driver to an autonomous mode.


According to the patent, Google is envisioning a landing strip for a vehicle. Only a landing strip that can be detected via sensors in addition to a GPS locator may be able to deliver the necessary detail to determine the exact location of a car, provide the vehicle with that location data and allow it to switch to an autonomous model. The patent stated that the location data as well as operation instruction can be provided via a URL. If such data is given to the vehicle, it may also receive information that it “can only operate in one predefined path.” At the very least, potential applications would be industrial vehicles as well as future cars that may park themselves in a parking lot. Keep in mind that these services could be closely tied to Google’s mapping services, which may be the connector to Google’s interest in this technology.

To develop this technology, Google employs some of the smartest minds in the industry. It is not really surprising to see Christopher Urmson and Nathaniel Fairfield listed among the inventors: Both joined Google from Carnegie Mellon’s Robotics Institute. Urmson was the technical leader of the Tartan racing team, which won the 2007 DARPA Urban Challenge: Their “Boss” vehicle, a heavily modified Chevy Tahoe, completed a 55 mile urban course in 4 hours and 10 minutes and won the $2 million prize of the competition. Also listed among the inventors is Nathan Fairfiled, also from Carnegie Mellon’s Robotics Institute, who worked on sonar data for navigation in 3D environments at the university.
