The invention provides a sun
visor control method and device and a vehicle, a display screen is arranged on a sun
visor, the method comprises the steps that when it is detected that the sun
visor is switched from a folded state to an open state, the ambient
light intensity of the eye area of a target passenger and angle information corresponding to a
light source in front of the vehicle are obtained; when it is determined that the
light source directly irradiates the eye area of the target passenger according to the angle information and the ambient
light intensity is larger than or equal to a preset threshold value, the sun shield is controlled to enter a sun-shading mode; when it is determined that the
light source does not directly irradiate the eye area of the target passenger, and / or the ambient
light intensity is smaller than a preset threshold value, the sun shield is controlled to enter a
multimedia mode. According to the method, whether the actual intention of opening the sunshade by the user is sunshade or not is predicted, if yes, the sunshade enters the sunshade mode, and if not, the sunshade enters the
multimedia mode, so that the user does not need to manually open the display when wanting to use the display, the user experience is improved, and the intelligence of the whole vehicle is improved.
