Vehicle driving assistance apparatus
First Claim
1. A driving assistance apparatus mounted in a vehicle, comprising:
- a maximum speed recognizer configured to, based on a captured image around the vehicle, recognize a maximum speed allowed for a lane in which the vehicle is traveling;
a recognized speed limit reporter configured to report a recognized speed limit that is the maximum speed recognized by the maximum speed recognizer;
a lane change detector configured to detect a lane change of the vehicle;
a lane position determiner configured to determine a position of a lane traveled by the vehicle immediately after the lane change detected by the lane change detector relative to a position of a lane traveled by the vehicle immediately before the lane change; and
a speed limits misrecognition verifier configured to, based on a positional relationship between the lanes traveled by the vehicle immediately before and after the lane change detected by the lane change detector and a comparison between recognized speed limits for the respective lanes traveled by the vehicle immediately before and after the lane change detected by the lane change detector, determine whether or not there is misrecognition of speed limits during travel of the vehicle,wherein the recognized speed limit reporter is configured to, if determined that there is misrecognition of speed limits, report the recognized speed limit to a driver of the vehicle in a prescribed manner.

Abstract
In a driving assistance apparatus mounted in a vehicle, a detector detects a lane change of the vehicle, a determiner determines a position of a lane traveled by the vehicle immediately after the lane change detected by the detector relative to a position of a lane traveled by the vehicle immediately before the lane change, and a verifier determines whether or not there is misrecognition of speed limits during travel of the vehicle based on a positional relationship between the lanes traveled by the vehicle immediately before and after the lane change detected by the detector and a comparison between recognized speed limits for the respective lanes traveled by the vehicle immediately before and after the lane change detected by the detector. If it is determined that there is misrecognition of speed limits, a reporter reports the recognized speed limit to a driver of the vehicle in a prescribed manner.
