[0024] The Head-Up Display (HUD) on a vehicle is a device that projects driving information onto the windshield in front of the driver or a transparent screen. The Head-Up Display allows the driver to see the required key information, such as speed, navigation instructions, warning information, etc., directly within the field of vision without having to lower his head to look at the dashboard or device screen.

[0025] In the current head-up display applications of vehicles, the display content is single and cannot meet the display needs of users in different driving scenarios.

[0026] In response to the above technical problems, this specification provides a control method for a head-up display, so as to dynamically adjust the content of displayed information on the head-up display according to changes in the vehicle's driving speed, so as to adapt to driving scene requirements at different driving speeds.

[0027] Next, the embodiments of this specification are described in detail.

[0028] like Figure 1 As shown, Figure 1 1 is a flowchart of a method for controlling a head-up display according to an exemplary embodiment of the present specification, including steps 101-102:

[0029] Step 101: When the dynamic display function of the head-up display is turned on, a target display strategy corresponding to the current speed interval to which the speed belongs is determined according to the current driving speed of the vehicle, and different speed intervals correspond to different display strategies.

[0030] This solution can provide setting options for the dynamic display function of the head-up display on the front-end operation interface of the vehicle system. When the dynamic display function is turned on, the following can be performed: Figure 1A control method for a head-up display. When the dynamic display function of the head-up display is not turned on, the head-up display can be controlled to display the content of the initialization information. Among them, the default initialization information can be freely set by the manufacturer before leaving the factory. For example, the initialization information may include the vehicle's driving speed information and the vehicle's energy information, so that the head-up display can display the current vehicle's driving speed information and the vehicle's energy information. Of course, when the dynamic display function of the head-up display is not turned on, if the user customizes other display information in the setting item of the display theme, the display information set by the user can be displayed. For example, if the user-defined display information only includes driving speed information, the current vehicle's driving speed information can be displayed in the head-up display.

[0031] In one embodiment, if Figure 2 As shown, Figure 2 This is a schematic diagram of the correspondence between the speed interval, the display strategy and the information to be displayed according to an exemplary embodiment of this specification. The correspondence between the speed interval, the display strategy and the information to be displayed can be preset. Among them, different speed intervals correspond to different display strategies. The speed interval can be a union of multiple non-continuous speed sub-intervals. For example, the union of different speed sub-intervals corresponding to the same display strategy can be regarded as the same speed interval, and the display strategy can be set for the speed interval. (0, v1] and (v3, v4] are two speed sub-intervals, and their union can be regarded as the same speed interval, which both correspond to the same display strategy 1, and the information to be displayed is A. The speed interval can also include a single speed sub-interval. For example, a single speed interval (v1, v2] corresponds to display strategy 2, and a single speed interval (v2, v3] corresponds to display strategy 3. The information indicated by different display strategies is not exactly the same. For example, the information to be displayed indicated by display strategy 1 includes A, and the information to be displayed indicated by display strategy 2 includes A, B and C. The information indicated by display strategy 1 and display strategy 2 both include the same information A, but are not exactly the same. The information to be displayed indicated by display strategy 3 includes C and D, and the information indicated by display strategy 3 is completely different from that indicated by display strategy 1 and display strategy 2. The information to be displayed can refer to an information object. For example, A represents vehicle speed information, B represents fuel information, C represents surrounding environment information, D represents time information, and E represents warning information. A, B, C, D, and E are all information to be displayed.

[0032] In this embodiment, different speed intervals often correspond to different driving scenarios. By setting different display strategies for different speed intervals, the information displayed on the head-up display can be continuously adjusted as the vehicle speed changes, thereby adapting to changes in driving scenarios. For example, if it is determined that the current speed of the vehicle is in the speed interval (v1, v2], the head-up display can be controlled to display the contents of A, B, and C; if it is determined that the current speed of the vehicle is increased to the speed interval (v2, v3], the head-up display can be controlled to adjust the display information to D and E.

[0033] In one embodiment, when the information to be displayed indicated by any two display strategies includes the same information, the information is displayed in different ways by the head-up display under different display strategies. The difference in display mode may specifically be the layout, position, font size, font color, animation effect, etc. of the information. For example, Figure 2 As shown, the information to be displayed indicated by display strategy 1 and display strategy 2 respectively include A (vehicle speed information), and the information can be displayed in different ways by the head-up display under display strategy 1 and display strategy 2. For example, display strategy 1 indicates that the vehicle speed information is displayed in a small font and light color at the lower left corner of the display area. Display strategy 2 indicates that the vehicle speed information is displayed in a large font and bright color in the middle of the display area.

[0034] In this embodiment, even if the content of the display information of different display strategies is consistent, the priority of the information in the current display content can be highlighted or weakened by adjusting the style of the display information (such as color, font, and position, etc.) to adapt to the display requirements of the display information in driving scenarios in different speed ranges.

[0035] In one embodiment, the user can customize the speed range, display strategy, and information to be displayed corresponding to the display strategy for the dynamic display function. For example, the user can set the range of the speed range and select the information to be displayed in the head-up display for the speed range. Of course, the manufacturer can also set the default speed range, display strategy, and information to be displayed corresponding to the display strategy for different driving scenarios. When the dynamic display function of the head-up display is turned on, the corresponding information is displayed in different speed ranges according to the default display strategy set by the manufacturer.

[0036] In one embodiment, the number of times the vehicle's driving speed switches between different speed intervals within a first duration is detected, and when the number is greater than the number threshold, the currently executed target display strategy remains unchanged within the second duration. For example, the vehicle can divide the time into time intervals, each time interval consisting of a first duration and a second duration. At the beginning of each first duration, the vehicle can start to periodically collect the vehicle's current driving speed, and determine whether the speed interval to which the vehicle's driving speed collected at the current moment belongs is different from the speed interval to which the vehicle's driving speed collected at the previous moment belongs. If different, the number of switching times is accumulated until the end of the first duration, and it is determined whether the accumulated total number of switching times is greater than the number threshold. In the case where the number of switching times is greater than the number threshold, the currently executed target display strategy remains unchanged within the second duration. For example, in the case where the number of switching times is greater than the number threshold, although the current driving speed of the vehicle is switched to other speed intervals within the second duration, the currently executed target display strategy can be prohibited from switching to other display strategies corresponding to the other speed intervals. In the case where the number of switching times is less than the number threshold, in response to detecting that the vehicle's driving speed is switched to other speed intervals within the second duration, display is performed according to other display strategies corresponding to other speed intervals.

[0037] When the vehicle speed switches frequently, the frequent changes in display strategy may distract the driver's attention and affect driving safety. In this embodiment, by locking the display strategy for a period of time when the vehicle speed switches frequently, the driver's interference with information changes can be reduced, allowing him to focus on the driving task.

[0038] In one embodiment, in different display strategies corresponding to each speed interval below the preset speed threshold, the amount of information to be displayed indicated by each display strategy is positively correlated with the speed size of the speed interval corresponding to the display strategy. And / or, in different display strategies corresponding to each speed interval not lower than the preset speed threshold, the amount of information to be displayed indicated by each display strategy is negatively correlated with the speed size of the speed interval corresponding to the display strategy. The preset speed threshold can be set to 80km / h, and the preset speed threshold can divide the driving scene of the vehicle into a high-speed driving scene and a non-high-speed driving scene. For non-high-speed driving scenes, the amount of information to be displayed can increase with the increase of vehicle speed, so that as the speed increases, the driver can obtain more information. For high-speed driving scenes, the amount of information to be displayed decreases with the increase of vehicle speed, so that as the speed increases, the information is continuously simplified, and the driver only focuses on key information to avoid driver distraction. This specification does not limit the number of speed intervals set below the preset speed threshold, and the number of speed intervals above the preset speed threshold. As mentioned above, the information to be displayed may be different information objects such as vehicle speed information, fuel quantity information, and warning information, and the number of information to be displayed may be the number of different information objects. Figure 2 As shown, the information to be displayed corresponding to display strategy 1 is A, and the number of information to be displayed indicated by display strategy 1 is 1. Similarly, the information to be displayed corresponding to display strategy 2 is A, B and C, and the number of information to be displayed indicated by display strategy 2 is 3. In the speed intervals (0, v1] and (v1, v2] lower than the preset speed threshold v2, the number of information to be displayed indicated by display strategy 1 and display strategy 2 is 1 and 3 respectively. In the speed intervals (v2, v3] and (v3, v4] not lower than the preset speed threshold v2, the number of information to be displayed indicated by display strategy 3 and display strategy 1 is 2 and 1 respectively.

[0039] In one embodiment, when the current speed of the vehicle is less than the first speed threshold, the first display strategy is determined as the target display strategy, and the subject of the information to be displayed indicated by the first display strategy includes the surrounding environment information of the vehicle and / or the first basic driving information. When the current speed of the vehicle is not less than the first speed threshold, the second display strategy is determined as the target display strategy, and the information to be displayed indicated by the second display strategy includes the second basic driving information. When the current speed is less than the first speed threshold, since the driver needs to pay more attention to the surrounding environment of the vehicle, the information to be displayed indicated by the first display strategy includes the surrounding environment information of the vehicle. At this time, the environmental information around the vehicle can be displayed in the head-up display, which can help the driver make quick decisions without lowering his head and avoid the need to check the rearview mirror frequently. When the current speed is not less than the first speed threshold, the information to be displayed indicated by the second display strategy includes the second basic driving information, but does not include the surrounding environment information of the vehicle. This allows the driver to focus more on the road conditions and vehicle speed ahead, avoiding the impact of the frequent pop-up environmental information around the vehicle on the driver's attention.

[0040] The vehicle's surrounding environment information may include obstacle information around the vehicle, and the obstacle may include pedestrians, other vehicles or road obstacles, etc. The above is only an exemplary description, and the vehicle's surrounding environment information may also include road condition information around the vehicle.

[0041] The vehicle's surrounding environment information refers to the information of the interaction between the vehicle and the external environment, which can be understood as a general term for the vehicle's external information and is not limited to a specific information. Correspondingly, basic driving information refers to the vehicle status or the information of the interaction between the vehicle and the driver, which can be understood as a general term for the vehicle's internal information and is not limited to a specific information. The first basic driving information and the second basic driving information belong to the subject of basic driving information, and the difference is that the information included in the first basic driving information and the second basic driving information is not exactly the same. For example, the first basic driving information may include vehicle speed information and fuel level information, while the second basic driving information may include vehicle speed information and navigation information.

[0042] The vehicle's surrounding environment information is taken as an example of obstacle information around the vehicle. Figure 3 As shown, Figure 3This specification is a flowchart for determining a target display strategy according to an exemplary embodiment. After the vehicle is started, it can be determined whether the dynamic display function is turned on. If the dynamic display function is not turned on, the head-up display can be controlled to display the content of the initialization information. When the dynamic display function is turned on, it can be determined whether the current driving speed of the vehicle is less than the first speed threshold. When the current driving speed of the vehicle is less than the first speed threshold, the first display strategy can be determined as the target display strategy, and the information to be displayed indicated by the first display strategy includes obstacle information around the vehicle and / or the first basic driving information. Specifically, it is determined whether there are obstacles around the vehicle. When there are obstacles, the information to be displayed indicated by the first display strategy may only include obstacle information around the vehicle, or the information to be displayed indicated by the first display strategy may include obstacle information around the vehicle and the first basic driving information. When there are no obstacles, the information to be displayed indicated by the first display strategy may only include the first basic driving information. When the current driving speed of the vehicle is not less than the first speed threshold, the second display strategy is determined as the target display strategy, and the information to be displayed indicated by the second display strategy may include the second basic driving information.

[0043] In one embodiment, it is possible to Figure 3 The first display strategy may include a first display sub-strategy and a second display sub-strategy. Figure 4 As shown, Figure 4This specification shows another flow chart of determining a target display strategy according to an exemplary embodiment. When the vehicle computer is started, it is determined whether the dynamic display function is turned on. If the dynamic display function is not turned on, the head-up display can be controlled to display the content of the initialization information. When the dynamic display function is turned on, it is determined whether the current driving speed of the vehicle is less than the second speed threshold. When the current driving speed of the vehicle is less than the second speed threshold, the first display sub-strategy is determined as the target display sub-strategy. The information to be displayed indicated by the first display sub-strategy includes obstacle information around the vehicle and / or the first basic driving sub-information. Specifically, it is determined whether there are obstacles around the vehicle. When there are obstacles, the information to be displayed indicated by the first display sub-strategy may only include obstacle information around the vehicle, or include obstacle information around the vehicle and the first basic driving sub-information. When there are no obstacles, the information to be displayed indicated by the first display sub-strategy may only include the first basic driving sub-information. When the current driving speed of the vehicle is not less than the second speed threshold and less than the first speed threshold, the second display sub-strategy is determined as the target display sub-strategy, and the information to be displayed indicated by the second display sub-strategy includes obstacle information around the vehicle and / or the second basic driving sub-information. Specifically, it is determined whether there are obstacles around the vehicle. If there are obstacles, the information to be displayed indicated by the second display sub-strategy may include only the obstacle information around the vehicle, or include the obstacle information around the vehicle and the second basic driving sub-information. If there are no obstacles, the second display sub-strategy may include only the second basic driving sub-information. If the current driving speed of the vehicle is not less than the first speed threshold, the second display strategy is determined as the target display strategy.

[0044] The amount of information to be displayed indicated by the first display sub-strategy may be less than the amount of information to be displayed indicated by the second display sub-strategy. For example, the information to be displayed indicated by the first display sub-strategy may include vehicle speed information, while the information to be displayed indicated by the second display sub-strategy may include vehicle speed information and fuel quantity information. When the vehicle turns from low speed to medium speed, the amount of displayed information is increased, so that the driver can make driving decisions based on more driving information.

[0045] Step 102: Acquire target information to be displayed indicated by the target display strategy, and control the head-up display to display the target information to be displayed.

[0046] Specifically, Figure 5 As shown, Figure 5This is a hardware schematic diagram of controlling the head-up display to display information shown in this specification according to an exemplary embodiment. The domain controller can obtain the current driving speed sent by the speed sensor, and determine the target display strategy corresponding to the current speed range to which the speed belongs according to the current driving speed, and obtain the current content of the target information to be displayed from the camera, radar or other modules for the target information to be displayed indicated by the target display strategy, and control the head-up display to display the current content. Of course, the head-up display can also be controlled to project the content to different locations by controlling the motor, or to control the head-up display to display other information. This specification does not limit this. Of course, when the head-up display is an external head-up display and the external head-up display can execute Figure 1 In the case of the method, the execution subject of this solution can also be an external head-up display.
