Research on Correction Algorithm of Head-up Display System in Vehicle Vibration 2020-01-1368

The HUD(Head Up Display) system can superimpose the driving assistance information on the reality to assist the driver in driving. However, when the road conditions are quite bad, the driving assistance information could not coincide well with the reality. This paper presents a correction algorithm for a heads up display system. The algorithm calculates the offset between the driving assistance information and the reality according to the unevenness of the road and the inclination of the vehicle, and then adjusts the position of the driving assistance information. In this paper, according to the unevenness of the road, the algorithm could confirm the tilt state of the vehicle and calculate the tilt angle of the vehicle. The offset of the driving assistance information is calculated according to the inclination angle of the vehicle, and then the position of the driving assistance information is adjusted to coincide with the reality. Finally, a mathematical simulation model is established to verify the reliability of the correction algorithm by inputting the unevenness of the road and the position of the real object in the driver's field of vision.
