Title:
DRIVING ASSISTANCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/003932
Kind Code:
A1
Abstract:
Driving assists have been insufficient because whether or not a vehicle will collide with an obstacle when leaving a garage, has not been determined. On the assumption that a vehicle 700 is turned to the left side while moving forward along a traveling route 702 created from the current steering angle, the vehicle 700 is expected to be positioned in a future position 703. A search region 704 is set in an area lateral to the inner wheel side of a vehicle 700' in the future position 703. The search region 704 is a rectangular region defined by the distance d from the traveling route 702 and the vehicle length p. In the present embodiment, in the case where an obstacle 705 is located near the outer wheel side of the vehicle 700', it is determined that the vehicle 700' will not collide with the obstacle 705. On the other hand, in the case where an obstacle 706 is located inside the search region 704, it is determined that the vehicle 700' will collide with the obstacle 706.
