Abstract

In a driving assisting device in which a receiver acquires the time-series traffic signal information regarding a lighting state of the traffic signal and a display and a speaker provide the lighting time information regarding a time remaining until a red signal of the traffic signal changes, the display and the speaker provide the lighting time information regarding the time remaining until the red signal of the traffic signal changes only when it is confirmed from the traffic signal information that a signal after change of the red signal permits traveling of the host vehicle. Accordingly, for example, for a light color change or the like in which an arrow lamp other than the traveling direction lights up after a red signal, a red signal waiting time is not displayed. This makes it possible to suppress factors inducing a careless driver to start driving.

Claims

1. A driving assisting device comprising:

acquisition means for acquiring time-series traffic signal information regarding a lighting state of a traffic signal; and

information providing means for providing lighting time information regarding a time remaining until a red signal of the traffic signal changes on the basis of the traffic signal information acquired by the acquisition means,

wherein the information providing means provides the lighting time information regarding the time remaining until the red signal of the traffic signal changes only when it is confirmed from the traffic signal information that a signal after change of the red signal permits traveling of a host vehicle.

3. The driving assisting device according to claim 1,

wherein the information providing means changes a manner of provision of the lighting time information according to reliability of confirmation from the traffic signal information that a signal after change of the red signal permits traveling of a host vehicle.

2. A driving assisting device comprising:

an acquisition section which acquires time-series traffic signal information regarding a lighting state of a traffic signal; and

information providing means for providing lighting time information regarding a time remaining until a red signal of the traffic signal changes on the basis of the traffic signal information acquired by the acquisition section,

wherein the information providing means provides the lighting time information regarding the time remaining until the red signal of the traffic signal changes only when conditions where stopping of a host vehicle is predicted are satisfied, and

the conditions where the stopping of the host vehicle is predicted are changed according to the road inclination where the host vehicle is located.

4. The driving assisting device according to claim 2,

wherein the conditions where the stopping of the host vehicle is predicted are that the speed of the host vehicle is equal to or smaller than a threshold value and a brake pedal of the host vehicle is pressed down.

5. (canceled)
