Abstract: A vehicle system includes: a map processing unit that creates local map data based on high accuracy map data and a position of an own vehicle; and an autonomous driving control unit that creates a travel plan for autonomous traveling of the own vehicle based on the local map data and controls traveling of the own vehicle according to the travel plan. The map processing unit creates multiple pieces of transmission data by dividing the local map data so as to correspond to regions on a map and transmits the multiple pieces of transmission data to the autonomous driving control unit. The map processing unit changes a shape and a size of the region on the map corresponding to each piece of transmission data based on selection information which decides a travel mode.

Abstract: A data compression method is used for compressing data indicating a gradient of a route.
