Device for controlling the position of an image in a head-up display |
摘要 |
A device for controlling the position of a symbolic image generated on a combiner by a head-up display system. Two tests are performed alternately: a general position test, using a luminous spot generated on the image; and a combiner position test, using a light source, fixed to the structure of the image generator and using the same collimating unit as this generator. The signals generated by each of these light sources are received by the same position sensor whose output signals are processed by the same circuit that varies the image's X and Y positioning voltages. The circuit incorporates an amplifier equipped with a gain switch that allows the amplifying gain to be set according to which test is being performed at any given time.
