A vehicle system includes: a map processing unit that creates local map data based on high-precision map data and a location of a host vehicle by extracting data of an area in the vicinity of the host vehicle; and an autonomous driving control unit that receives the local map data from the map processing unit, creates a driving plan for autonomous driving of the host vehicle based on the local map data, and controls driving of the host vehicle according to the driving plan. The map processing unit creates a plurality of pieces of transmission data by dividing the local map data into regions corresponding to a map and transmits the plurality of pieces of transmission data to the autonomous driving control unit. The map processing unit changes the amount of data per piece of transmission data based on road traffic information included in the high-precision map data.
一种车辆系统,包括:地图处理单元,其通过提取本车辆附近的区域的数据,基于高精度地图数据和所述本车辆的位置创建本地地图数据;以及自主驾驶控制单元,其从所述地图处理单元接收所述本地地图数据,基于所述本地地图数据创建用于所述本车辆的自主行驶的行驶计划,并且根据所述行驶计划控制所述本车辆的行驶。所述地图处理单元通过将所述本地地图数据划分为对应于地图上的区域来创建多条传输数据并将所述多条传输数据传输到所述自主驾驶控制单元。所述地图处理单元基于包含在所述高精度地图数据中的道路交通信息来改变每条传输数据的数据量。
