Abstract
A vehicle control device or method controls an output of a drive source of a vehicle based on a color of an illuminated signal of a traffic light in a vehicle-advancing direction during travel in autonomous driving. The vehicle control device includes a control unit that estimates the color of the currently illuminated signal of the traffic light based on oncoming vehicle information and controls the output of the drive source based on an estimation result when the color of the illuminated signal of the traffic light cannot be acquired by the onboard camera. The control unit limits the output of the drive source and reduces a vehicle speed from a current vehicle speed to a vehicle speed at which fuel efficiency is superior to that at the current vehicle speed when the color of the illuminated signal of the traffic light is estimated to be red.
