The invention discloses a method for adjusting the lighting direction of an automotive headlamp based on speed sensing. The method for adjusting the lighting direction of the automotive headlamp based on speed sensing comprises the steps that the traveling speed of an automobile is obtained and then is compared with a preset speed threshold value; when the traveling speed of the automobile is smaller than the preset speed threshold value, the vertical lighting direction of the automotive headlamp does not need to be adjusted; when the traveling speed of the automobile is larger than the preset speed threshold value, the lighting angle of the automotive headlamp is calculated according to the distance between the automotive headlamp and the ground after the safety brake distance is obtained through calculation, and then the lighting angle of the automotive headlamp is adjusted. The method for adjusting the lighting direction of the automotive headlamp based on speed sensing has the advantages that the design is simple, using is convenient, it is guaranteed that the lighting distance is larger than the safety brake distance when the automobile travels at a high speed, and driving is safer.
