DRIVING ASSISTANCE DEVICE FOR VEHICLE AND DRIVING ASSISTANCE METHOD FOR VEHICLE

摘要

A driving assistance device for a vehicle includes an object detection section for detecting objects present on the periphery of an own vehicle and determines whether the own vehicle is located within a predetermined region from an intersection. The driving assistance device extracts, from the detected objects, a first moving object which may come into collision with the own vehicle as the own vehicle enters the intersection. The driving assistance device extracts, from the detected objects, a second moving object crossing a road on which the first moving object is traveling between the own vehicle and the first moving object, and acquires motion information of the second moving object crossing the intersection. The driving assistance device determines that the own vehicle can enter the intersection when acquiring the motion information of the second moving object.

主权项

1. A driving assistance device for a vehicle comprising:
an own vehicle position detector for detecting a current position of an own vehicle on a map; an object detector for detecting objects present on a periphery of the own vehicle; an intersection determination circuit for determining whether the own vehicle is located within a predetermined region from an intersection without traffic light where two or more roads intersect based on the current position detected by the own vehicle position detector; a first moving object extraction circuit for extracting, from the objects detected by the object detector, a first moving object which may come into collision with the own vehicle as the own vehicle enters the intersection when the intersection determination circuit determines that the own vehicle is located within the predetermined position from the intersection; a second moving object extraction circuit for extracting, from the objects detected by the object detector, a second moving object crossing a road on which the first moving object is traveling between the own vehicle and the first moving object when the first moving object is extracted by the first moving object extraction circuit, and acquiring motion information of the second moving object crossing the intersection; and an intersection entry determination circuit for determining that the own vehicle can enter the intersection when the motion information of the second moving object crossing the intersection is acquired.
