The invention relates to the technical field of training equipment, in particular to a training simulator for motor vehicle drivers. For solving the problem that in the prior art, sheltered column bars exist in a wide picture display mechanism, the invention provides the following technical scheme: the simulator comprises a display mechanism and a circuit and the like; and the simulator is characterized in that the display mechanism comprises a projector (13) and a picture screen (4), wherein the projector is arranged at the rear part of the display mechanism, and the picture screen is arranged at the front part of the display mechanism and used for displaying pictures; the picture screen (4) is in the shape of plane or in the shape that the front part is protruded and the rear part is concave; when the picture screen (4) is in the shape of plane, the ratio of height to width thereof is more than 1:2.4; when the picture screen (4) is in the shape that the front part is protruded and the rear part is concave, the ratio of the height (h) of the picture screen to the width (w) of a horizontal line is more than 1:2.4. The simulator provided by the invention has the advantages that the problem that column bars are sheltered is solved, and the picture is wide, continuous, complete, and strong in liveness and reality; in addition, the pictures displayed on the simulator provided by the invention are unified, the brightnesses and colors of the pictures are unified, and the display contents of the same object are same when the same object is in different positions.
