该专利又叫“弱信号区域车辆位置识别”。这意味着，它将使用GPS和手机信号以外的技术来定位用户的车辆。苹果的专利文件称，该技术能通过驾驶员的智能手机自动探测车辆何时停泊（当手机不再有信号，也不再通过数据线或蓝牙信号与车辆相联的时候），并记录泊车的地点和时间长度。

The application, which includes a diagram of Apple’s headquarters as an example illustration, doesn’t specify the scenarios when the service would be useful. But this method could come in handy in parking structures and underground garages where smartphone signals can often be very weak.

该专利文件还使用了苹果的总部大楼地图作为图示，不过它并没有透露这项服务何时能够启用。但这种技术迟早是用得上的，特别是在手机信号往往很弱的地下停车场。

But as always, it’s entirely up to the company to actually turn a patent into a real product or actually enforce it against other companies. Keeping track of your car could remain your own responsibility, unfortunately.

但一如往常，苹果和谷歌何时能把这些专利变成看得见摸得着的产品，或是强制其他厂商执行这些专利，还得看它们自己的意愿。在短期内，在停车场停好车后，你还是得自己记牢爱车的位置。
