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 a predicted value indicating an occurrence probability of sudden lane change in the traffic lanes on the basis of statistical information acquired from a plurality of vehicles and an information quantity of the statistical information;
set an addition value, wherein the addition value in the traffic lanes in a direction intersecting the traveling direction of the vehicle is greater than the addition value in the traffic lanes along the traveling direction;
set a recommended lane on the basis of a sum of the predicted value and the addition value; and
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, a predicted value indicating an occurrence probability of sudden lane change in the traffic lanes 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 traffic lanes, the addition value being greater in a direction intersecting the traveling direction of the vehicle than the addition value in the traffic lanes along the traveling direction; 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.
