1. A driving support device for assisting a driver to drive a vehicle, the driving support device comprising:
- an intersection information acquirer to obtain signal light information about traffic signals installed at one or more intersections ahead of the vehicle on a road along which the vehicle is traveling and to obtain distances to the intersections;
a vehicle state detector to detect a position and speed of travel of the vehicle;
a signal passableness decider to decide a passable or impassable state of the traffic signals by the vehicle from the signal light information and the distances to the intersections the intersection information acquirer obtains, and from the position and speed of travel of the vehicle the vehicle state detector detects; and
a display controller to display, on a display, a map including;
the position of the vehicle; and
the passable or impassable state of the traffic signals decided by the signal passableness decider, the passable or impassable state of the traffic signals being indicated by changes of color on the map,wherein the passable state of the traffic signals are indicated by a first color on the map,wherein the impassable state of the traffic signals are indicated by a second color, different from the first color, on the map, andwherein the display controller displays a road passing through the intersection whose traffic signal is decided as passable from the vehicle position by the signal passableness decider in the first color, and displays a road passing through the intersection whose traffic signal is decided as impassable in the second color.

Abstract
A driving support device includes: an intersection information acquiring unit 3 to obtain signal light information about traffic signals installed at one or more intersections ahead of a road along which the vehicle is traveling and to obtain distances to the intersections; a vehicle state detector 4 to detect a position and speed of travel of the vehicle; a signal passableness deciding unit 5 to decide a passable or impassable state of the traffic signals by the vehicle from the signal light information, the distances to the intersections, and the position and speed of travel of the vehicle; and a display controller 7 to display the passable or impassable state of the traffic signals decided by the signal passableness deciding unit 5 by changes of color on the map.

9. A driving support method for assisting a driver to drive, comprising:
-
obtaining, by an intersection information acquirer, signal light information about traffic signals installed at one or more intersections ahead of the vehicle on a road along which the vehicle is traveling and obtaining distances to the intersections; detecting, by a vehicle state detector, a position and speed of travel of the vehicle; deciding, by a signal passableness decider, a passable or impassable state of the traffic signals by the vehicle from the signal light information and the distances to the intersections the intersection information acquirer obtains, and from the position and speed of travel of the vehicle the vehicle state detector detects; and displaying, on a display, by a display controller, a map including; the position of the vehicle; and the passable or impassable state of the traffic signals decided by the signal passableness decider, the passable or impassable state of the traffic signals being indicated by changes of color on the map, wherein the passable state of the traffic signals are indicated by a first color on the map, wherein the impassable state of the traffic signals are indicated by a second color, different from the first color, on the map, and wherein the displaying comprises displaying a road passing through the intersection whose traffic signal is decided as passable from the vehicle position by the signal passableness decider in the first color, and displaying a road passing through the intersection whose traffic signal is decided as impassable in the second color.

10. A driving support device for assisting a driver to drive a vehicle, the driving support device comprising:
-
an intersection information acquirer to obtain signal light information about traffic signals installed at two or more intersections ahead of the vehicle on a road along which the vehicle is traveling and to obtain distances to the intersections; a vehicle state detector to detect a position and speed of travel of the vehicle; a signal passableness decider to decide a passable or impassable state of the each of traffic signals installed at the two or more intersections by the vehicle from the signal light information and the distances to the intersections the intersection information acquirer obtains, and from the position and speed of travel of the vehicle the vehicle state detector detects; and a display controller to display a map including the position of the vehicle on a display, and to simultaneously and separately display the passable or impassable state of all of the traffic signals installed at the two or more intersections decided by the signal passableness decider by changes of color on the map, wherein the passable state of each of the traffic signals is indicated by a first color on the map, and wherein the impassable state of each of the traffic signals is indicated by a second color, different from the first color, on the map. - View Dependent Claims (11)
