大型汽车制造商美国跨国公司通用汽车(General Motors)于2018101日申请了一项专利,利用区块链技术的应用集成到车辆传感器,为自动驾驶汽车大大改进了导航地图。

该专利于2018101日提交,最近才在美国专利商标局的官方网站上发布。根据该专利,现有地图很难保持动态而不增加成本。

“一种用于更新汽车去中心化导航地图的系统,包括一个或多个用于评估和表征汽车周围环境的传感器,以及一个差异检测器,该差异检测器根据从汽车一个或多个传感器接收到的信息识别与已知导航地图相比周围环境的差异。差异会被传输到区块链地图网络。”

该公司改善当前导航地图并利用区块链导航地图的方法是,当许多车辆在城市中四处行驶时,将数据收集负载分担给这些车辆。然后,实时收集的数据将与差异检测器一起使用,该差异检测器将使用现有地图检查传入的数据。

检测到的任何差异将被传输到区块链网络,并将被其他移动车辆观察到相似的模式进行交叉检查。根据该专利,网络将由数据中心中的车辆和采矿节点维护。

这个基于区块链的导航系统是为通用汽车的“超级巡航”功能而设计的。 “超级巡游”功能为公司的某些豪华车型展示了半自动驾驶体验。分担数据收集以生成导航图将会在美国土地上覆盖大部分道路。
