The first and second PLC control module (5,6) is crossed to connect with projection module (1).
8. a kind of vehicle display device according to claim 7, which is characterized in that the first and second position coordinates detection
Module (3,4) is infrared radiation detection apparatus.
9. a kind of display methods for vehicle display device described in claim 1, which comprises the following steps:
S1: starting vehicle, multifunctional intellectual control module handle data, generate display image, are projected by projecting shaven head,
In projection screen display；
S2: vehicle-state detection module detects car speed V, and the information detected is sent to multifunctional intellectual control module
In processor；
S3: processor judges that car speed, specific deterministic process is as follows:
S3-1: judging whether car speed V > 0, if it is not, then projection screen and projection shaven head keep existing display position state constant,
Return step S2；If so, entering step S3-2；
S3-2: detecting the A1 point coordinate (x1, y1) of driver's left eye by first position coordinate measurement module, and the A2 point of right eye is sat
It marks (x2, y2), the midpoint A3 coordinate ((x1+x2)/2, (y1+y2)/2) of A1A2 is calculated in processing, passes through second position coordinate
Detection module detect projection screen central axes above B point coordinate (x3, y3) and below projection screen central axes C point coordinate (x4,
y4)；
S3-3: the plan range value of point A3 to B point is calculatedWith putting down for point A3 to C point
Face distance valueA value b is set, the value of b-Sab, b-Sac is calculated in processing；
S3-4: one threshold value c of setting judges whether satisfaction-c <b-Sab < c and-c <b-Sac < c, if it is not, then the first and second PLC is controlled
Molding block is respectively adjusted the position of projection shaven head and projection screen, and returns to step S3-2；If so, projection screen and throwing
Shadow shaven head keeps existing display position, carries out display image and shows, and returns to step S2；
S4: vehicle stall, projection screen and projection shaven head keep existing display position, and Projection Display terminates.
