The data input module includes a knob disposed on the electronic assembly. The knob rotates towards different directions to correspondingly input brightness adjusting and dimming signals.
And the data processing module generates a brightness adjusting command according to the preset brightness adjusting curve. The brightness adjusting curve is a curve generated by the environment brightness information and the brightness adjusting instruction together. The brightness adjusting curve is Z ═ alpha X + beta Y,
z brightness, and finally the brightness value of the head-up display is given by the brightness adjusting control module;
the X automatic brightness value is a value acquired by the automatic brightness acquisition module;
the Y manual brightness value is a brightness value set by the manual brightness module;
alpha is an automatic brightness coefficient, and the brightness value acquired by the automatic brightness acquisition module accounts for the proportion of the whole brightness value;
