Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle and a display method. Background Art

[0002] In order to ensure that drivers can drive vehicles more safely and stably, more and more vehicles are equipped with head-up displays. With the head-up display, various types of information such as navigation information, driving information, and environmental information can be superimposed and displayed in the driver's field of vision, thereby preventing the driver from looking down at the information and causing his or her vision to deviate from the road, resulting in dangerous driving. The light from the image source formed by the head-up display device is generally emitted from the bottom of the instrument panel to the front windshield of the vehicle, and then reflected from the front windshield to the human eye, so that the driver can observe the virtual image in front through the front windshield.

[0003] In the related art, the virtual image formed by the head-up display device is located on the ground in front of the vehicle. However, when the vehicle is running, if it encounters road conditions such as bumps on the road, it often shakes or sways. At this time, there will be relative movement between the virtual image and the ground, that is, the ground is not relatively static relative to the virtual image. In this way, when the human eye observes the virtual image, it is easy to get dizzy or eye fatigue, which will affect the safety of driving. Summary of the invention

[0020] Obtaining road information within a preset range in front of the vehicle;

[0021] Based on the road information, it is identified that there is a bumpy road surface within a preset range in front of the vehicle, and a first display instruction is generated, wherein the first display instruction is used to adjust the head-up display to a first display state.

[0022] Optionally, identifying that there is a bumpy road surface within a preset range in front of the vehicle and generating a first display instruction includes:

[0023] Based on the presence of a bumpy road surface within a preset range in front of the vehicle, determining a target distance between the bumpy road surface and the vehicle;

[0024] Determining a target time for the vehicle to reach the bumpy road surface based on the target distance and the current vehicle speed;

[0025] Based on the target time and the preset time period, an adjustment time is determined and the first display instruction is generated, wherein the first display instruction is used to instruct to adjust the head-up display starting from the adjustment time so that the head-up display is adjusted to the first display state at the target time.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0044] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0045] First, combining Figures 1 to 4 As shown, an embodiment of the present application provides a vehicle, which includes a head-up display 100 , a front windshield 200 , and a front hood 300 .

[0046] The head-up display 100 includes an image generation unit 110 and an optical component 120. The light of the image source generated by the image generation unit 110 is transmitted to the front windshield 200 through the optical component 120 to generate a virtual image in front of the front windshield 200, wherein the virtual image includes at least one target indication information. Generally, the target indication information can be various types of information such as navigation information, driving information, environmental information, and entertainment information. Therefore, the user can see the target indication information in the virtual image in front through the front windshield 200, and timely understand the driving environment or driving status of the vehicle, so as to improve driving safety. It should be noted that the image generation unit 110 in the embodiment of the present application can be composed of a TFT-LCD (Thin Film Transistor-Liquid Crystal Display) display module, or a mini-LED (mini-Light-Emitting Diode) display module, an OLED (Organic Light-Emitting Diode) display module, a micro-LED (micro-Light-Emitting Diode) display module, a DLP (Digital Light Processing) projection display module, an LBS (Laser Beam Scanning) display module, a LCOS (Liquid Crystal on Silicon) display module or a QLED (Quantum Dot Light Emitting Diodes) display module and other display modules.

[0047] When the head-up display 100 is in the first display state, the front bonnet 300 intersects with the virtual image plane 400 where the virtual image is located, so that the human eye can observe the virtual image in the virtual image plane 400 on the front bonnet 300. Since the virtual image formed by the head-up display 100 falls on the front bonnet 300, that is, the front bonnet 300 is the background of the virtual image, when the vehicle is in a bumpy state, the virtual image can move in unison with the vehicle body, and people generally move in unison with the vehicle body, so the human eye and the virtual image are in a relatively static state, thereby avoiding dizziness or eye fatigue when the human eye observes the virtual image, further improving driving safety.

[0048] The following is combined with Figures 1 to 5The composition details and functions of the vehicle provided in the embodiment of the present application are described in more detail.

[0049] like Figure 4 As shown, in some embodiments, the optical assembly 120 includes at least one first optical element 121 and at least one second optical element 122. Either one of the first optical element 121 and the second optical element 122 is a curved mirror, and the other is a curved mirror or a plane mirror. The light of the image source of the image generating unit 110 passes through the first optical element 121 and the second optical element 122 and is projected onto the front windshield 200. It should be noted that the number of the first optical element 121 and the second optical element 122 can be adjusted according to factors such as the vehicle model and the surrounding environment of the vehicle. The curved mirror can be a convex mirror and / or a concave mirror, and the curved mirror can be a spherical mirror and / or an aspherical mirror. It should be noted that the type of the first optical element 121, the type of the second optical element 122, and the type of the front windshield in the optical assembly 120 can be adjusted according to actual needs, as long as it is ensured that the light of the image source of the image generating unit 110 can be reflected onto the front windshield 200 after passing through the optical assembly 120, and the virtual image surface 400 can be placed at a specified position.

[0050] like Figures 1 to 3 As shown, in some embodiments, the front endpoint position of the front hood 300 is the first position 310. It should be noted that the front endpoint of the front hood 300 refers to the position on the front edge of the front hood 300 that is farthest from the human eye. The center position of the human eye is the second position 500. When the head-up display 100 is in the first display state, the midpoint of the upper edge of the virtual image plane 400 is the third position 410. Among them, in the vertical direction, the third position 410 does not exceed the line connecting the first position 310 and the second position 500. In this way, it can be ensured that all virtual images in the virtual image plane 400 can be presented on the front hood 300, so that all virtual images can remain relatively still with the human eye.

[0051] like Figure 5 As shown, in some embodiments, the virtual image plane 400 includes a display area 420 and a non-display area 430, the display area 420 is used to display the target indication information, and the midpoint of the upper edge of the virtual image plane 400 is the midpoint of the upper edge of the display area 420. It can be understood that a portion of the outer edge area of ​​the virtual image plane 400 is the non-display area 430. According to the above arrangement, it can be ensured that the target indication information in the display area 420 can be presented with the front hatch 300 as the background to avoid dizziness or eye fatigue when the human eye observes the target indication information, and it can also ensure that the content in the display area 420 of the virtual image plane 400 is not too low, so that it is convenient for the human eye to observe the target indication information, thereby improving the driving safety.

[0052] In some embodiments, the angle formed by the line connecting the first position 310 and the second position 500 and the line connecting the center position of the virtual image surface 400 and the second position 500 is the first angle. Figures 1 to 3 As shown, the vertical viewing angle θ of the human eye is the second angle. The second angle is twice the first angle. It should be understood that the upper limit direction of the vertical viewing angle θ of the human eye is the direction of the line connecting the first position 310 and the second position 500. This arrangement can ensure that the center position of the virtual image plane 400 is located at the center of the vertical viewing angle θ of the human eye. Since the lower limit direction of the viewing angle β of the human eye is the direction of the center line of the vertical viewing angle θ, the virtual image plane 400 is equivalent to being in the focusing position of the human eye, which is more conducive to the human eye observing the virtual image in the virtual image plane 400.

[0053] like Figure 8 As shown, in some embodiments, the vehicle further includes a driving mechanism 700, which is connected to the image generation unit 110, and the driving mechanism 700 is used to move the image generation unit 110 to change the head-up display 100 from the second display state to the first display state. It should be understood that by moving the position of the image generation unit 110, the distance between the virtual image plane 400 and the human eye can be adjusted, for example, the distance between the virtual image plane 400 and the human eye can be shortened so that the virtual image plane 400 falls on the front hood 300. Among them, when the head-up display 100 is in the second display state, the virtual image plane 400 intersects with the ground 600. It should be noted that the intersection of the virtual image plane 400 and the ground 600 means that the ground 600 is the background of the virtual image plane 400. In the first display state, the virtual image plane 400 can be combined with the road on the ground 600, and the target indication information of the virtual image can be better integrated with the real road. Since the driving mechanism 700 can change the state of the head-up display 100 from the second display state to the first display state, when the vehicle is in a bumpy state, the virtual image plane 400 can be adjusted to the front hood 300 in time, so as to ensure that when the vehicle is in a bumpy state, the virtual image and the human eye can remain relatively still, which can not only enable people to understand the target indication information in time, but also avoid dizziness or eye fatigue in the human eye, further improving driving safety. At the same time, the driving mechanism 700 can change the display position of the virtual image in time when the vehicle is bumpy, thereby improving the flexibility of virtual image display.

[0054] like Figure 8As shown, in some embodiments, the vehicle further includes a rotation mechanism 800, which is connected to the optical assembly 120, and the rotation mechanism 800 is used to rotate the angle of the optical assembly 120, for example, to rotate the angle of the curved mirror and / or the reflector, so as to change the head-up display 100 from the second display state to the first display state. It should be understood that by rotating the optical assembly 120, the height of the center position of the virtual image plane 400 relative to the front hood 300 can be adjusted so that the center of the virtual image plane 400 is within the lower viewing angle β range suitable for human eye observation, so as to meet the viewing requirements of human eyes.

[0055] It should be noted that the virtual image plane 400 may have various angles and positions. This application takes the following three methods as examples for illustration:

[0056] The first one, such as Figure 1 As shown, the virtual image plane 400 is perpendicular to the horizontal plane passing through the lower edge of the virtual image plane 400. Therefore, human eyes can see the virtual image on the front hood 300 through the front windshield 200.

[0057] The second type, such as Figure 2 As shown, the virtual image plane 400 forms a first preset angle with the horizontal plane passing through the lower edge of the virtual image plane 400, and the first preset angle is less than 90 degrees. In some embodiments, the first preset angle is 0 to 50 degrees. In other embodiments, the first preset angle is 0 to 30 degrees. It should be noted that the inclined virtual image plane 400 is more suitable for the downward observation habit of the human eye, which improves the comfort of the human eye when observing the virtual image.

[0058] The third type, such as Figure 3 As shown, the vertical distance between the upper edge of the virtual image plane 400 and the front hatch 300 is less than the height of the virtual image plane 400. It should be noted that, from the perspective of light propagation, part of the virtual image plane 400 passes through the front hatch 300, but in actual image presentation, the part of the virtual image plane 400 located below the front hatch 300 is still displayed with the upper surface of the front hatch 300 as the background, and the human eye can observe the complete virtual image content in the virtual image plane 400.

[0059] It should be understood that any of the above three display modes can ensure that the virtual image plane 400 is presented with the front bonnet 300 as the background, and the virtual image content in the virtual image plane 400 can be displayed completely on the front bonnet 300. Since the sizes of the front bonnet 300 of different car models and the heights of human eyes in the cockpit are different, any of the above suitable display modes can be selected for different car models to ensure that the virtual image can fall on the front bonnet 300.

[0060] On the other hand, an embodiment of the present application also provides a display method. Figure 61 is a flow chart of a display method provided in an embodiment of the present application. The display method provided in an embodiment of the present application is applied to any of the above-mentioned vehicles, and can generally be executed by a controller 900 of the vehicle.

[0061] The display method provided in the embodiment of the present application includes the following steps 101 to 102.

[0062] In step 101 , the controller 900 obtains road information within a preset range in front of the vehicle.

[0063] In some embodiments, the preset range is a semicircular area with the vehicle as the center and R as the radius, where R is greater than 0. Thus, the road information within the forward range of the vehicle can be analyzed more comprehensively and accurately. It should be noted that the road information can be image information of the road within the preset range, which the controller 900 can obtain from the navigation system configured for the vehicle, or from an image acquisition device provided on the vehicle, which can be, for example, a camera, or from a vehicle-mounted drone configured for the vehicle.

[0064] In step 102, the controller 900 identifies the presence of a bumpy road surface within a preset range in front of the vehicle based on the road information, and generates a first display instruction.

[0065] The first display instruction is used to adjust the head-up display 100 to the first display state. With this arrangement, when the vehicle passes over a bumpy road, the virtual image plane 400 of the head-up display 100 can be timely adjusted to a position intersecting with the front hood 300, thereby ensuring that the human eye and the virtual image are in a relatively static state, avoiding dizziness or eye fatigue caused by observing the virtual image when driving on a bumpy road, and improving driving safety.

[0066] Figure 7 1 is a flow chart of a display method provided in an embodiment of the present application. The display method provided in an embodiment of the present application is applied to any of the above-mentioned vehicles, and can generally be executed by a controller 900 of the vehicle.

[0067] The display method provided in the embodiment of the present application includes the following steps 201 to 206.

[0068] In step 201 , the controller 900 obtains road information within a preset range in front of the vehicle.

[0069] It should be noted that step 201 is the same as step 101, so the embodiment of the present application will not be described in detail here.

[0070] In step 202, the controller 900 identifies the presence of a bumpy road surface within a preset range in front of the vehicle based on the road information.

[0071] In some embodiments, a model capable of identifying a bumpy road surface based on road information, such as an image classification model, may be pre-stored in the controller 900. When the road information is image information, the controller 900 may input the image information into the image classification model and determine whether there is a bumpy road surface based on the image classification output result.

[0072] In step 203 , the controller 900 determines a target distance between the bumpy road surface and the vehicle based on the presence of a bumpy road surface within a preset range in front of the vehicle.

[0073] In some embodiments, the target distance is the distance between the position closest to the front end point of the vehicle's hood 300 in the section where the bumpy road is located and the front end point of the vehicle's hood 300.

[0074] In step 204 , the controller 900 determines the target time for the vehicle to reach the bumpy road surface based on the target distance and the current vehicle speed.

[0075] In some embodiments, the current vehicle speed is the average speed of the vehicle within the target time period. This allows for a more accurate determination of the target time for the vehicle to reach the bumpy road. It should be understood that the target distance divided by the current vehicle speed is the preset driving time required for the vehicle to reach the bumpy road. The controller 900 obtains the current time, and determines the target time based on the current time and the preset driving time. For example, if the current time is 7 o'clock and the preset driving time is 10 minutes, the target time is 7:10.

[0076] In step 205 , the controller 900 determines the adjustment time based on the target time and the preset time period and generates a first display instruction.

[0077] Among them, the first display instruction is used to instruct the adjustment of the head-up display 100 from the adjustment time, so that the head-up display 100 is adjusted to the first display state at the target time. It should be noted that the preset time period refers to the time required for the head-up display 100 to adjust from the current state to the first display state. The preset time period can be set by the designer of the vehicle, or it can be adjusted according to user habits. The adjustment time is obtained by subtracting the preset time period from the target time. For example, if the target time is 7:10 and the preset time period is 1 minute, the adjustment time is 7:09. With this setting, the head-up display 100 can be adjusted to the first display state in advance to ensure that when the vehicle just arrives at the bumpy road, the virtual image surface 400 of the head-up display 100 is already in a position to fall on the front hood 300, avoiding dizziness or eye fatigue in the human eye when the vehicle is driving on a bumpy road.

[0078] It should be noted that the first display instruction is used to instruct the adjustment of the head-up display 100 from the adjustment moment, which means that the first display instruction is used to instruct the driving mechanism 700 and / or the rotating mechanism 800 to adjust the position of the image generation unit 110 and / or the position of the optical component 120 in the head-up display 100 from the adjustment moment, so that the head-up display 100 is adjusted to the first display state at the target moment, that is, the virtual image plane 400 is adjusted to a position intersecting with the front deck at the target moment. In some embodiments, the controller 900 is electrically connected to the driving mechanism 700, and the controller 900 sends the first adjustment instruction to the driving mechanism 700. In response to receiving the first adjustment instruction, the driving mechanism 700 changes the head-up display 100 from the second display state to the first display state. In other embodiments, the controller 900 is electrically connected to the driving mechanism 700 and the rotating mechanism 800, respectively, and the controller 900 sends the first adjustment instruction to the driving mechanism 700 and the rotating mechanism 800. In response to receiving the first adjustment instruction, the driving mechanism 700 and the rotating mechanism 800 change the head-up display 100 from the second display state to the first display state. It should be noted that the adjustment principle of the driving mechanism 700 and the rotating mechanism 800 is the same as the adjustment principle of the driving mechanism 700 and the rotating mechanism 800 in the vehicle provided in the above-mentioned embodiment of the present application, so the embodiment of the present application will not be repeated here.

[0079] In some embodiments, step 205 further includes:

[0080] The controller 900 obtains the current display state of the head-up display 100. It should be noted that the current display state is the off state or the second display state. When the head-up display 100 is in the off state, the virtual image plane 400 is not generated. When the head-up display 100 is in the second display state, the virtual image plane 400 intersects with the ground 600, and at this time the ground 600 is the background of the virtual image plane 400.

[0081] The controller 900 determines a preset time period for adjusting from the current display state to the first display state based on the current display state. The controller 900 determines the adjustment time and generates a first display instruction based on the target time and the preset time period. It is understandable that the display state of the head-up display 100 may be different during the driving of the vehicle. Since the above method can determine the preset time period according to the different current display states of the head-up display 100, the adjustment time can be determined more accurately, thereby ensuring that when the vehicle reaches the bumpy road section, the virtual image surface 400 generated by the head-up display 100 has been presented on the front hood 300, that is, the position of the virtual image surface 400 is pre-adjusted. In other words, the display method provided in the embodiment of the present application, by combining the current display state of the head-up display 100, can more accurately and timely pre-adjust the state of the head-up display 100 to the first display state, so that the human eye can observe the virtual image on the front hood 300 from the beginning of the vehicle reaching the bumpy road section, thereby improving the driving safety.

[0082] In some embodiments, when the vehicle is traveling on a non-bumpy road, the controller 900 controls the head-up display 100 to be in the second display state, at which time the ground 600 is the background of the virtual image plane 400, so that the virtual image in the virtual image plane 400 can be better integrated with the road or environment of the ground 600. The above adjustment method can avoid premature adjustment of the virtual image position, ensure that the virtual image of the head-up display 100 can be displayed on the non-bumpy road for a long time before being adjusted to the position in the first display state, and improve the integration effect on the non-bumpy road.

[0083] In step 206 , the controller 900 identifies that there is no bumpy road surface within a preset range in front of the vehicle based on the road information, and generates a second display instruction.

[0084] Among them, the second display instruction is used to adjust the head-up display 100 from the first display state to the second display state. It should be noted that the principle of road recognition in step 206 is the same as the principle of road recognition in step 202, that is, both can be recognized using an image classification model, so the embodiment of the present application will not be repeated here. Using the display method of the embodiment of the present application, the display state of the head-up display can be adjusted in time according to the type of road surface in front of the vehicle, so that the position of the virtual image surface can timely adapt to the needs of the human eye to observe the virtual image, avoid dizziness or eye fatigue in the human eye, and thus improve driving safety.
