摘要： 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.

摘要： Provided is a vehicle control system for avoiding a collection between a right-turning vehicle and a straight-through vehicle without decreasing comfort for an occupant. In the system, a first vehicle V1 and a second vehicle V2 retain high-precision map data for identifying a traveling lane. When the first vehicle V1 traveling in an autonomous driving mode intends to turn right from a right turn lane at an intersection ahead based on the high-precision map data, the first vehicle V1 transmits a right turn notification indicating the intention to turn right to nearby vehicles using vehicle-to-vehicle communications. When the second vehicle V2 traveling in an autonomous driving mode intends to travel straight at an intersection ahead, the second vehicle V2 recognizes a right-turning vehicle in an oncoming lane at the intersection upon receiving the right turn notification from the right-turning vehicle, and performs a predetermined control for collision avoidance.

摘要： A data compression method is used for compressing data indicating a gradient of a route. The data compression method includes: acquiring a gradient table that shows gradient values in respective sections arranged between a starting point of the route and an ending point thereof, the sections including one section and an adjacent section adjacent to the one section: ranking the gradient values; and in a case where the gradient value of the one section and the gradient value of the adjacent section are in a same rank, integrating the gradient value of the one section and the gradient value of the adjacent section and generating a compressed gradient table that shows a distance and a corresponding rank of the section having the same rank.
