8. A vehicle display device according to claim 7, wherein the first and second position coordinate detecting means (3, 4) are infrared detectors.
9. A display method for the vehicle display device according to claim 1, characterized by comprising the steps of:
s1: starting a vehicle, processing data by the multifunctional intelligent control module to generate a display image, projecting through the projection optical head, and displaying on the projection screen;
s2: the vehicle state detection module detects the vehicle speed V and sends the detected information to a processor in the multifunctional intelligent control module;
s3: the processor judges the vehicle speed, and the specific judging process is as follows:
s3-1: judging whether the vehicle speed V is greater than 0, if not, keeping the state of the existing display position of the projection screen and the projection optical head unchanged, and returning to the step S2; if yes, entering step S3-2;
s3-2: detecting coordinates (x 1, y 1) of a point A1 of a left eye and coordinates (x 2, y 2) of a point A2 of a right eye of a driver through a first position coordinate detection module, processing and calculating to obtain coordinates ((x 1+ x 2)/2, (y 1+ y 2)/2) of a midpoint A3 of the point A1A2, and detecting coordinates (x 3, y 3) of a point B above a central axis of a projection screen and coordinates (x 4, y 4) of a point C below the central axis of the projection screen through a second position coordinate detection module;
s3-3: calculating the plane distance value from the point A3 to the point B
Plane distance value from point A3 to point C
Setting a value b, and processing and calculating to obtain values of b-Sab and b-Sac;
s3-4: setting a threshold value c, judging whether-c < b-Sab < c and-c < b-Sac < c are met, if not, respectively adjusting the positions of the projection optical head and the projection screen by the first PLC control module and the second PLC control module, and returning to the step S3-2; if yes, keeping the existing display position of the projection screen and the projection optical head, displaying the display image, and returning to the step S2;
s4: and the vehicle is shut down, the projection screen and the projection optical head keep the existing display position, and the projection display is finished.
