The patent says, ‘the vehicle may include sensors which detect an object such as a pedestrian attempting or about to cross the roadway in front of the vehicle.'

该专利显示：“无人驾驶汽车可能配有传感器，用于检测是否有行人意图或即将于车前横穿马路。”

'The vehicle’s computer may then determine the correct way to respond to the pedestrian.'

“无人驾驶汽车的电脑将因此采取正确的应对方式。”

'The vehicle may then provide a notification to the pedestrian of what the vehicle is going to do or is currently doing.'

“而后，汽车会告知行人它的行进计划或目前的行驶方向。”

This past Halloween, Google was teaching cars how to recognize children in their costumes, part of a feature that is educating them how to react and act around children.

刚过去的万圣节期间，谷歌对无人驾驶汽车进行了试验，让它们学会辨认儿童的身影。该计划也是无人汽车儿童适应性的一部分。

And this patent takes this feature one step forward by including all pedestrians.

这项新专利则让上述性能更进了一步——将所有行人都考虑在内。

There is also an indication of an eye or robotic arm will be added that could notify pedestrians the car has ‘seen’ them.
