The invention provides a vehicle-mounted virtual imaging system, a vehicle-mounted virtual imaging method and a vehicle with the vehicle-mounted virtual imaging system.
Fig. 1 is a system block diagram of a vehicle-mounted virtual imaging system according to a first embodiment of the present invention, and fig. 2 is a schematic structural diagram of the vehicle-mounted virtual imaging system according to the first embodiment of the present invention. As shown in fig. 1 and 2, the vehicle-mounted virtual imaging system according to the first embodiment of the present invention includes a speed acquisition unit 10 for acquiring a vehicle speed, a control unit 20, and a virtual imaging device 30 for displaying a virtual image, where the virtual imaging device 30 includes a display size adjustment device 31 for adjusting a display distance of the virtual image. The speed acquisition unit 10 and the display size adjustment device 31 are electrically connected to the control unit 20, the speed acquisition unit 10 transmits the acquired vehicle speed information to the control unit 20, and the control unit 20 controls the display size adjustment device 31 in the virtual imaging device 30 to adjust the size of the virtual image according to the vehicle speed information.
In the present embodiment, by providing the display size adjustment device 31 in the virtual imaging device 30 and adjusting the size of the virtual image in accordance with the speed of the vehicle, the driver can intuitively feel the speed of the vehicle in accordance with the size of the virtual image display when driving the vehicle. Particularly, in the process of vehicle acceleration or deceleration, the faster the vehicle changes, the faster the size of the virtual image changes, and the driver can subconsciously adjust the vehicle speed when seeing the virtual image so as to ensure the safety of vehicle running. That is, the vehicle-mounted virtual imaging system provided by the embodiment of the invention can better assist the driver in driving the vehicle.
Further, in the embodiment, the speed of the vehicle and the size of the virtual image have a positive correlation, and the larger the speed of the vehicle is, the larger the size of the virtual image is; the smaller the vehicle speed, the smaller the size of the virtual image. Through the arrangement, the size of the virtual image is larger and larger when the vehicle speed is faster and faster, so that a driver can clearly feel the improvement of the vehicle speed; likewise, as the vehicle speed becomes slower, the size of the virtual image becomes smaller and smaller so that the driver can clearly feel the decrease in the vehicle speed.
In the present embodiment, the corresponding relationship between the vehicle speed and the size of the virtual image may be preset in the control unit 20, and since the vehicle speed changes gradually, the size of the virtual image also has a trend of gradually increasing or decreasing when the vehicle speed changes.
In the present embodiment, the speed acquisition unit 10 may be a vehicle speed sensor of a vehicle.
Referring to fig. 2, in the present embodiment, the virtual imaging device 30 is a Head Up Display (HUD) system, such as an AR-HUD (enhanced Head Up Display (AR-HUD) system. The head-up display system includes a light source 32 and a reflector, and light emitted from the light source 32 passes through a display screen (not shown) and is reflected by the reflector to project an image on the display screen onto a screen such as a front windshield 40. Correspondingly, the display size adjusting device 31 includes a distance adjusting mechanism 311 and an incident angle adjusting mechanism, the distance adjusting mechanism 311 is connected to the light source 32 and can drive the light source 32 to move so as to change the distance between the light source 32 and the adjacent reflector, the incident angle adjusting mechanism is connected to the reflector and can drive the reflector to rotate so as to change the incident angle when the light irradiates the reflector.
More specifically, in the present embodiment, the reflecting mirror includes a first reflecting mirror 331 and a second reflecting mirror 332, and the first reflecting mirror 331 is disposed closer to the light source 32 than the second reflecting mirror 332 is on the imaging optical path. Accordingly, the incident angle adjusting mechanism includes a first incident angle adjusting mechanism 3121 connected to the first reflecting mirror 331, and a second incident angle adjusting mechanism 3122 connected to the second reflecting mirror 332. The distance adjustment mechanism 311 adjusts the distance between the light source 32 and the first reflector 331.
In this structure, as the vehicle speed becomes slower, the distance adjustment mechanism 311 may move the light source 32 to increase the distance between the light source 32 and the first reflector 331. The first incident angle adjusting mechanism 3121 rotates the first mirror 331 counterclockwise to decrease the angle of the incident angle (see α in fig. 2) on the first mirror 331, and the second incident angle adjusting mechanism 3122 rotates the second mirror 332 counterclockwise to increase the angle of the incident angle (see β in fig. 2) on the second mirror 332, by which the size of the virtual image becomes smaller and smaller. On the contrary, when the vehicle speed is faster and faster, the distance adjustment mechanism 311 moves the light source 32 to decrease the distance between the light source 32 and the first reflecting mirror 331, the first incident angle adjustment mechanism 3121 rotates the first reflecting mirror 331 clockwise to increase the angle of the incident angle on the first reflecting mirror 331, and the second incident angle adjustment mechanism 3122 rotates the second reflecting mirror 332 clockwise to decrease the angle of the incident angle on the second reflecting mirror 332, so that the size of the virtual image is increased by the above adjustment.
Fig. 3 is a schematic structural diagram of a vehicle-mounted virtual imaging system according to a second embodiment of the present invention. As shown in fig. 3, the vehicle-mounted virtual imaging system according to the second embodiment of the present invention is substantially the same as the first embodiment, except that in this embodiment, the virtual imaging device 30 may be a pair of smart glasses, which includes a light source 32 and a reflective channel 34, and correspondingly, the display size adjusting device 31 includes a light source angle adjusting mechanism 313, and the light source angle adjusting mechanism 313 is connected to the light source 32 and adjusts the light emitting angle of the light source 32.
The intelligent glasses can be wirelessly connected with the vehicle to acquire the speed of the vehicle.
In this configuration, as the vehicle speed becomes slower and slower, the light source angle adjustment mechanism 313 rotates the light source 32 counterclockwise to decrease the angle of the incident angle (see γ in fig. 3) entering the light reflection path 34, so that the size of the virtual image becomes smaller and smaller during imaging after the light emitted from the light source 32 is reflected in the light reflection path 34; as the vehicle speed increases, the light source angle adjusting mechanism 313 rotates the light source 32 clockwise to increase the angle of the incident angle into the light reflecting path 34, so that the size of the virtual image increases as the image is formed.
In this embodiment, the reflective channel 34 may be disposed in the side of the glasses, so that the smart glasses have a longer light path reflection distance.
Fig. 4 is a schematic flowchart of an imaging method of the vehicle-mounted virtual imaging system according to the embodiment of the present invention. As shown in fig. 4, the present invention further provides an imaging method based on the above vehicle-mounted virtual imaging system, which includes the following steps:
s1: acquiring speed information of a vehicle;
s2: and adjusting the size of the virtual image according to the speed of the vehicle.
Further, in the present embodiment, the vehicle speed and the display distance of the virtual image have a positive correlation, and the larger the vehicle speed, the larger the size of the virtual image, and the smaller the vehicle speed, the smaller the size of the virtual image.
As described above, in the present invention, the display size adjustment device 31 is provided in the virtual imaging device 30, and the display distance is adjusted according to the speed of the vehicle, so that the driver can intuitively feel the speed of the vehicle according to the distance displayed by the virtual image when driving the vehicle. Particularly, in the process of vehicle acceleration or deceleration, the faster the vehicle changes, the faster the size of the virtual image becomes, and the driver can subconsciously adjust the vehicle speed when seeing the virtual image so as to ensure the safety of vehicle running. That is, the vehicle-mounted virtual imaging system provided by the embodiment of the invention can better assist the driver in driving the vehicle.
