Abstract: The autonomous driving system includes an internal vehicle camera, a vehicle detection device, and a processor configured to detect an angle of a facial direction or a line of sight of the driver, judge whether the driver has checked safety of the surroundings of the vehicle based on the angle, and control autonomous driving of the vehicle. The processor is configured to start a lane change of the vehicle when it is judged that the driver has checked the safety of the surroundings of the vehicle. The processor is configured to judge that the driver has checked the safety when a first condition has been satisfied if another vehicle has not been detected in a destination lane, and judge that the driver has checked the safety when a second condition more severe than the first condition has been satisfied if another vehicle has been detected in the destination lane.

Abstract: A travel controller detects, from an image representing the face of a driver of a vehicle, an act of the driver checking surroundings of the vehicle, records a time at which the act of checking is detected, and suggests to the driver a lane change for the vehicle to change a travel lane to an adjoining lane. In the case that the act of checking is detected in a precheck period before a suggestion time at which the lane change is suggested, the travel controller makes the vehicle execute the lane change regardless of whether the act of checking is detected in a post-suggestion check period after the suggestion time of the lane change.
