HEAD-UP DISPLAY IMAGE POSITION CONTROL DEVICE FOR REGULATING AUTOMATICALLY ANGLE OF A PROJECTING MIRROR OF A HEAD-UP DISPLAY DEVICE BY MEASURING THE POSTURE CHANGE OF THE VEHICLE BY WEIGHT CHANGE, SPEED, AND BRAKING OF THE VEHICLE

摘要

PURPOSE: A head-up display image position control device is provided to adjust automatically the angle of a projecting mirror according to a posture change of the vehicle by an automatic leveling device for regulating the vertical change of a head lamp. CONSTITUTION: A head-up display device for projecting vehicle traveling information about vehicle traveling speed, RPM(Revolution Per Minute) of an engine, and the amount of fuel on a wind shield glass(13) is composed of a projector(10) for showing vehicle information; a reflecting mirror(11) for reverberating the projected image; a projecting mirror(12) for throwing the reflected image on the wind shield glass and changing automatically projection angle according to a posture change of the vehicle; a projection angle control unit(20) for regulating the projection angle of the projecting mirror; and a controller(40) for measuring the posture change of the vehicle and sending a control signal to the projection angle control unit by computing a projection control angle of the projecting mirror.
