Patent Images
1. A driving assistance device comprising:
- an acceleration operation amount detection unit configured to detect an acceleration operation amount of an acceleration operator operated by a driver to instruct acceleration;
a driving force control unit configured to generate the acceleration depending on the acceleration operation amount detected by the acceleration operation amount detection unit in a host vehicle;
an imaging unit configured to acquire a captured image obtained by capturing a periphery of the host vehicle;
a line detection unit configured to detect a line positioned on a road surface from the captured image;
a crossing detection unit configured to detect a crossing based on the captured image;
a parking frame extraction unit configured to extract a parking frame based on the line detected by the line detection unit; and
an acceleration suppression control unit configured to suppress the acceleration when the parking frame extraction unit extracts a parking frame and a crossing is not detected in the captured image and not to suppress the acceleration when the parking frame extraction unit detects a parking frame and a crossing is detected in the captured image.

Abstract
A driving assistance device improves the accuracy of driving assistance for parking. A traveling controller detects a line positioned on a road surface from a captured image captured by a camera. A parking frame is extracted from the detected line and acceleration suppression control of a vehicle is executed based on the extracted parking frame. At this time, the acceleration suppression control is cancelled if a crossing is detected based on the captured image.
