Google Patents Autonomous Car?to-Pedestrian Communication System
The gestation of the fully autonomous car is turning up all manner of new hurdles. Google, which has tested its own, vaguely koala-esque self-driving car (it plans to supply systems to automakers rather than become a full automaker, however), has proposed a solution to one such problem: how autonomous cars will communicate with pedestrians. As the Washington Post discovered, the Silicon Valley giant has filed a patent to address the issue.
Car-to-pedestrian communication is far more interesting than it sounds. It’s said that, were an autonomous car to approach a four-way stop, it would theoretically never “go” through the intersection, since it’d be constantly waiting on pedestrians or other traffic to cross in front of it. For self-driving cars to become a reality, they’re going to need to bone up on their assertiveness. Being able to communicate with foot traffic is a key step in the right direction, especially since people can’t make eye contact with or receive hand signals from a robotic car. At least not yet.
Google’s patent, therefore, more or less involves a dynamic array of signage and audible warnings?which we had fun with in our own illustration at the top; that’s not part of Google’s patent?for self-driving cars. The first sentence in the patent’s abstract sums it up perfectly: “Aspects of the disclosure relate generally to notifying a pedestrian of the intent of a self-driving vehicle.&...
