Abstract
A GPS and a map information database acquire information regarding an arrow light which displays a signal for prohibiting travel in a particular direction, such as a red arrow light. A display and a loudspeaker supply information to a motorist of a host vehicle based on the information acquired by the GPS and the map information database, or a brake ECU and a brake actuator brake the host vehicle without depending on the manipulation by the motorist based on the information acquired by the GPS and the map information database. As a result, it is possible to correctly support driving even when a red arrow light or the like for prohibiting travel in a right turn direction.
