Traffic lane guidance system for vehicle and traffic lane guidance method for vehicle
First Claim
1. A traffic lane guidance system for a vehicle for guiding a driver of the vehicle to a recommended lane in which the vehicle is recommended to run from among traffic lanes included in a route from a current point of the vehicle as a first point to a destination point of the vehicle as a second point, comprising:
- a vehicle component mounted on the vehicle to output guidance information for the driver; and
a processor configured to;
calculate, when the vehicle runs in sections corresponding to a plurality of links, a predicted value indicating an occurrence probability of sudden lane change in the links by connecting a plurality of nodes corresponding to traffic lanes in a traveling direction of the vehicle and a direction intersecting the traveling direction of the vehicle, for each of the plurality of links on the basis of statistical information acquired from a plurality of vehicles and an information quantity of the statistical information;
calculate an addition value in the links set by connecting the plurality of nodes in the direction intersecting the traveling direction of the vehicle, the addition value being greater than an addition value in the links set by connecting the plurality of nodes in the traveling direction of the vehicle;
set a recommended lane on the basis of a sum of the predicted value and the addition value; and
output guidance information output guidance information via the vehicle component to the driver according to the recommended lane.

Abstract
A lane guidance system for a vehicle for guiding a vehicle to a recommended lane in which the vehicle is recommended to run out of traffic lanes included in a route from a first point to a second point through the use of an output unit mounted on the vehicle includes: a calculating unit that calculates a predicted value of an occurrence probability of sudden lane change as information indicating the occurrence probability of sudden lane change when the vehicle runs in sections corresponding to a plurality of links; a setting unit that sets the recommended lane on the basis of the predicted value; and a generating unit that generates guidance information for the recommended lane and that outputs the guidance information to the output unit.

11. A traffic lane guidance method for a vehicle of guiding a driver of the vehicle to a recommended lane in which the vehicle is recommended to run from among traffic lanes included in a route from a current point of the vehicle as a first point to a destination point of the vehicle as a second point through the use of a vehicle component mounted on the vehicle to output guidance information for the driver and a processor, the method comprising:
-
calculating, using the processor, when the vehicle runs in sections corresponding to a plurality of links, a predicted value indicating an occurrence probability of sudden lane change in the links by connecting a plurality of nodes corresponding to traffic lanes in a traveling direction of the vehicle and a direction intersecting the traveling direction of the vehicle, for each of the plurality of links on the basis of statistical information acquired from a plurality of vehicles and an information quantity of the statistical information; calculating an addition value in the links set by connecting the plurality of nodes in the direction intersecting the traveling direction of the vehicle, the addition value being greater than an addition value in the links set by connecting the plurality of nodes in the traveling direction of the vehicle; setting a recommended lane on the basis of a sum of the calculated predicted value and the addition value; and outputting guidance information via the vehicle component to the driver according to the recommended lane.
