Title: METHOD FOR CONTROLLING A HEAD-UP DISPLAY AND HEAD-UP DISPLAY
Abstract:
The invention concerns a method for controlling a head-up display (10) for a motor vehicle (V) which comprises an image generating unit (12) capable of emitting a light beam transporting images (Img), and an attenuation unit (14) for attenuating the luminous intensity of said light beam, said control method comprising: - a step of compiling an instruction for controlling a light source (12A) of the image generating unit, - a step of compiling an instruction for controlling the attenuation unit, and - a step of controlling said light source and said attenuation unit according to the two control instructions; wherein the control instruction of the attenuation unit is compiled according to the setting of a parameter relative to the luminous intensity of said light beam with respect to a threshold value.
