First Claim
Patent Images
1. A traveling condition determination device for use in a vehicle, the device comprising:
- an imaging unit configured to periodically capture an image of a road on which the vehicle is traveling;
a recognition unit configured to recognize, in the image periodically captured by the imaging unit, a marker on a side of the road relative to the vehicle;
a detection unit configured to detect an angle of the vehicle relative to an arrangement of the marker recognized by the recognition unit;
a storage unit configured to store a transition of the angle of the vehicle detected by the detection unit over a period of time;
a pattern memory unit configured to store pattern models of angle transitions that correspond to traveling conditions, anda determination unit configured to determine a traveling condition of the vehicle based on a comparison between the transition of the angle stored in the storage unit and the pattern models stored in the pattern memory unit.
