Abstract
Official abstract text for this publication.
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 by extracting data of regions near the own vehicle; and an autonomous driving control unit that receives the local map data from the map processing unit, 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 data amount of each piece of transmission data based on road traffic information contained in the high accuracy map data.
First claim
Opening claim text (preview).
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; and an autonomous driving control unit that receives the local map data from the map processing unit, 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, wherein 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, and the map processing unit changes a data amount of each piece of transmission data based on road traffic information contained in the high accuracy map data. 2 . The vehicle system according to claim 1 , wherein the map processing unit changes at least one of a shape and a size of the region on the map corresponding to each piece of transmission data based on the road traffic information. 3 . The vehicle system according to claim 1 , wherein the map processing unit acquires a congestion degree of a road on which the own vehicle is traveling based on the road traffic information, and the higher the congestion degree is, the larger the map processing unit makes the region on the map corresponding to each piece of transmission data. 4 . The vehicle system according to claim 1 , wherein the map processing unit creates the transmission data such that the transmission data is divided for each lane. 5 . The vehicle system according to claim 4 , further comprising a map guidance unit that, based on a set destination, sets a route to the destination, wherein the map processing unit decides a recommended lane on which the own vehicle should travel based on the route to the destination, and transmits the transmission data corresponding to the recommended lane to the autonomous driving control unit. 6 . The vehicle system according to claim 1 , wherein the map processing unit creates the multiple pieces of transmission data such that a data amount of each piece of transmission data is within a prescribed range.
