DRIVING SUPPORT APPARATUS, DRIVING SUPPORT METHOD, AND VEHICLE

摘要

An object of the present invention is to provide a technique wherein a traveling lane is set as definitely as possible to perform the warning or the support so that a vehicle is allowed to travel smoothly in the traveling lane. The present invention resides in a driving support apparatus for setting a traveling lane in which a vehicle can travel on the basis of a traveling-prohibited region and performing warning or support so that the vehicle is allowed to travel in the traveling lane if the vehicle is to be departed from the traveling lane; wherein the traveling lane is set while raising a level of reliability as information to recognize the traveling lane from the traveling-prohibited region if the traveling-prohibited region is continuous in a travel direction of the vehicle as compared with if the traveling-prohibited region is discontinuous in the travel direction of the vehicle.

主权项

1. A driving support apparatus for a vehicle comprising:
a detector configured to detect a traveling-prohibited region; and an electronic control unit configured to:
set a traveling lane on the basis of the traveling-prohibited region detected by the detecting unit;determine and give a level of recognition to the set traveling lane based on an accuracy of the detected traveling-prohibited region, the level of recognition indicating an accuracy of the set traveling lane;perform a drive support process in order to avoid a departure of the vehicle from the set traveling lane, the drive support process being performed based on the set traveling lane when the level of recognition of the set traveling lane is at least a threshold value; andraise the level of recognition given to the set traveling lane when the detected traveling-prohibited region is continuous in a travel direction of the vehicle, as compared to the level of recognition given to the traveling lane when the traveling-prohibited region is discontinuous in the travel direction of the vehicle.
