The invention provides a lane decision method for automatic driving vehicles based on a multi-objective
decision matrix. The lane decision method includes the following steps that (1), a left lane, alane where the automatic driving vehicles are located and a right lane of the automatic driving vehicles are regarded as to-be-decided lanes, continuous-running distance and speed-limiting informationof each to-be-decided lane are collected, quantification is carried out on the information of each to-be-decided lane and evaluated information of each to-be-decided lane is obtained; (2), the information of barriers, closest relative to the
vertical distance of the automatic driving vehicles, of the front side and the back side of each to-be-decided lane is collected, current location and speedinformation of the two barriers on the front and back and the location information after
setting time are judged, and the relative distance the two barriers on the front and back relative to the automatic driving vehicles correspondingly at the
current time and
setting time is calculated; (3), integral evaluating information of the to-be-decided lanes is obtained by arranging the above informationand the
decision matrix is formed; and (4), a decision lane is obtained by dealing with and calculating the
decision matrix, so that the real-time independent lane deciding of the automatic driving vehicles is achieved.
