【谷歌无人驾驶汽车开启“人性化”探索,可向司机和行人鸣笛】据报道Google 最近发布一篇关于无人驾驶汽车的月度报告。报告显示 Google 的无人驾驶汽车团队正在调校无人汽车内置的人工智能系统。通过调校,无人汽车能够在合适的条件下可以发出鸣笛声,避免干扰正在驾驶的人类驾驶员。这也表明谷歌对于无人驾驶汽车的探索已经开始朝人性化的角度发展。http://www.looooker.com/?p=28973

Google Self-Driving Cars Are Now Allowed to Honk

Mjc2MTYxMg

Google self-driving cars are now allowed to honk when appropriate. That’ll likely be rare in the company’s Mountain View, Calif. home turf but more common, no doubt, should the car ever make it to Manhattan.

Honking is particularly valuable because it compensates for the inhuman silence of the electric drive on which Google’s cars depend. “Quiet isn’t always a good thing,” Google says in its latest monthly report. “Pedestrians and cyclists often rely on sound to alert them to a nearby car, particularly if they’re about to cross the street or change lanes. For people with visual impairments, the sound of an approaching vehicle can be critical information.”

The car can honk either to announce its presence or to scream “Stop!” at someone who needs screaming at. “If another vehicle is slowly reversing towards us, we might sound two short, quieter pips as a friendly heads up to let the driver know we’re behind,” Google says. “However, if there’s a situation that requires more urgency, we’ll use one loud sustained honk.”

Google’s engineers have fine-tuned their algorithm by listening to their program honk privately, via sounds emitted inside the cabin of the car, and by grading each instance for propriety. Evidently the hard part is deciding whether to tap the horn—or to lean on it.

The tapping, “I’m here” kind of honk appears to have been going on for some time. Back in October a Google spokesperson told Mashable that the car had honked on at least one occasion to announce its presence to a car emerging from a driveway.

Google’s report also records another accident. On May 4 a Google car—which at the time was being driven manually, that is, by a human being—struck a median in Mountain View while travelling at 14 kilometers per hour (9 mph), involving no other vehicle, causing no injuries, and damaging the car only slightly. The company’s fleet has had a number of accidents, but only one—a fender-bender with a public bus—in which the Google car was at fault.

Editor’s note: this article has been corrected to emphasize that the May 4 accident occurred when a human driver was in charge of the car.
