PROBLEM TO BE SOLVED: To provide a vehicle driving support device capable of suppressing a projection beam forming an optical pattern projected on a road surface from dazzling the driver of the other vehicle without being applied on the road surface when traveling at a point where the downward gradient of the road surface increases accompanying the increase of a distance from an own vehicle.SOLUTION: A vehicle driving support device Uf mounted on a vehicle to display a predetermined optical pattern Q on a road surface around an own vehicle so as to enable recognition of the driver of the own vehicle or the other vehicle, a pedestrian or an environment state detector includes a road surface projection optical system Up for scanning a light source beam Fb by radiated light from a coherent light source Ds to output a projection beam Fo, and projecting the optical pattern Q to the road surface around the own vehicle, road surface presence information holding means Uw for holding information about whether a road surface is present at the projection scheduled point of the projection beam Fo, and a control circuit Ec for controlling the road surface projection optical system Up.SELECTED DRAWING: Figure 1 |
