DRIVING SUPPORTING DEVICE
First Claim
1. A driving supporting device which predicts a light color state of a first traffic signal that a vehicle is due to pass, comprising:
- a light color state acquisition means for acquiring a light color state of a second traffic signal installed before the first traffic signal;
a light color change cycle acquisition means for acquiring the light color change cycle of the first traffic signal on the basis of the light color change cycle of the second traffic signal; and
a light color state predicting means for predicting the light color state of the first traffic signal when the vehicle arrives at the first traffic signal on the basis of the light color state of the second traffic signal acquired by the light color state acquisition means and the light color change cycle of the first traffic signal acquired by the light color change cycle acquisition means.

Abstract
In this driving supporting device, the light color change cycle of a prediction object traffic signal is acquired on the basis of the light color change cycle of a prediction basis traffic signal installed before the prediction object traffic signal, and the light color state of the prediction object traffic signal when the vehicle arrives at the prediction object traffic signal is predicted on the basis of the light color state of the prediction basis traffic signal and the light color change cycle of the prediction object traffic signal. Thus, since the light color change cycle of the prediction object traffic signal is acquired on the basis of the light color change cycle of the prediction basis traffic signal, it becomes possible to predict a light color state even in the case of a traffic signal which cannot transmit information indicating its light color change cycle.
