1. A vehicle system comprising:
a map processing unit that creates local map data based on high accuracy map data and a position of an own vehicle by extracting data of regions near the own vehicle from the high accuracy map data;
an autonomous driving control unit that receives the created local map data from the map processing unit, creates a travel plan for autonomous traveling of the own vehicle based on the created local map data, and controls traveling of the own vehicle according to the travel plan; and
a map guidance unit that, based on a set destination, sets a route to the destination,
wherein the map processing unit creates multiple pieces of transmission data by dividing the created local map data so as to correspond to regions on a map, selects, from the multiple pieces of transmission data, pieces of transmission data corresponding to regions having a distance from the own vehicle less than or equal to a prescribed distance and including the route to the destination as first transmission data, and transmits the first transmission data to the autonomous driving control unit with a higher priority than other pieces of the multiple pieces of transmission data,
wherein the map processing unit further selects, from the multiple pieces of transmission data, pieces of transmission data corresponding to regions having a distance from the own vehicle less than or equal to the prescribed distance and including a branch route that branches off from the route to the destination as second transmission data, and further transmits the second transmission data to the autonomous driving control unit with a higher priority than other pieces of the multiple pieces of transmission data excluding the first transmission data, and
wherein the map processing unit further selects, from the multiple pieces of transmission data, pieces of transmission data corresponding to regions having a distance from the own vehicle less than or equal to the prescribed distance and including a merging route that merges with the route to the destination as third transmission data, and further transmits the third transmission data to the autonomous driving control unit with a higher priority than other pieces of the multiple pieces of transmission data excluding the first transmission data and the second transmission data.
