AUTOMATIC DRIVE ASSIST DEVICE, METHOD, AND PROGRAM FOR A VEHICLE

摘要

Automated drive assisting devices, methods, and programs for a vehicle acquire road information including information on a lane change prohibited section of a road on which the vehicle travels, and determine whether a lane change is to be made at a branch point for guidance positioned ahead of the vehicle during automated drive. The devices, methods, and programs determine, based on the road information, whether the vehicle is traveling on a road with the lane change prohibited section. When it is determined that a lane change is to be made at the branch point for guidance and the vehicle is traveling on the road on with the lane change prohibited section, the devices, methods, and programs cause the vehicle to make a lane change in a section other than the lane change prohibited section before the branch point for guidance.
