DRIVING ASSISTANCE DEVICE

Disclosed is a driving assistance device which improves the accuracy of driving assistance for parking. A traveling controller 10 detects a line positioned on a road surface from a captured image captured by a camera 1. 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.
