- the second value I2 is the value of the light intensity radiated in a cone centered around the second direction 18, this cone having for example an angle at the top (aperture measured in the plane of the entrance pupil of the second device 23) between 5 ° and 30 °.
- the second measuring device 23 is preferably oriented towards the projection mirror 8 of the projection optical system.
- the second measuring device 23 of the system control 17 is arranged in the housing 14 of the display so as to measure the second value I2 of the light intensity coming from the second direction 19, after reflection on the projection mirror 8 of the projection optical system.
- the second mirror 8 is generally inclined relative to the horizontal at an angle of 45 ° to 85 ° so that the light entering the display 2 through the window 15 in the second direction 19 is reflects on this second mirror 8 towards the second measuring device 23.

- the control method of the invention makes it possible, among other things, to efficiently manage the case where the motor vehicle 1 enters and then leaves a tunnel. automobile.
- the second value I2 of the light intensity coming from above the vehicle 1 is high (in the case of a clear or cloudy sky for example), greater at the predetermined luminosity threshold Ith, while the first value 11 of the light intensity coming from the front of the vehicle 1 begins to decrease (approaching the tunnel entrance) to fall below the luminosity threshold value Ith just before or when entering the tunnel.
- the brightness value of display 2 is then set to a low value in anticipation of entry into the tunnel and the decrease in ambient brightness so that virtual image 10 does not have too high a brightness which would risk dazzling driver 3 (the latter then driving in a low-light environment) but has sufficient brightness to be visible to him.
- the second value I2 of the light intensity coming from above the vehicle 1 is low (the second measuring device 23 is then aimed at the ceiling of the tunnel), lower at the predetermined luminosity threshold Ith, and the first value 11 of the light intensity coming from the front of the vehicle 1 begins to increase (approaching the exit of the tunnel) to pass above the luminosity threshold value Ith just before or when exiting the tunnel.
- the brightness value of display 2 is then set to a high value in anticipation of the exit of the tunnel and the increase in ambient brightness so that virtual image 10 has sufficient brightness to be visible by driver 3 (the latter then driving in a bright environment).
- these may be predefined constants.
- these may be values which will be defined for example as a function of the time or of the first and second values 11, I2 of light intensity.
- the brightness threshold Ith this will, for example, be a constant whose value will be adjusted by means of tests on a test vehicle.
