Abstract

The invention relates to the field of automobile auxiliary driving technology and provides a method and device for automobile auxiliary driving and an automobile. The method comprises the following steps that a radar arranged on the automobile is used to probe whether an obstacle exists in a preset measuring range; when the obstacle is probed in the preset measuring range, the driving speed of the automobile is obtained; whether the obstacle is a moving object or not is judged according to the driving speed, when it is determined that the obstacle is the moving object, the relative speed between the automobile and the moving object is calculated; the needed time for reaching a preset safety distance between the automobile and the moving object is obtained according to the relative speed; and the current light pattern of the automobile is obtained; and when the light pattern is a high beam, a user is prompted to switch the high beam to a low beam through voice at a preset time point before the needed time, so that when the automobile meets the moving object on an opposite lane, the user is prompted to switch the high beam and the low beam at the precise time point, and the safety of automobile driving is improved.
