[0013] The technical solutions provided by the embodiments of this specification may have the following beneficial effects:

[0014] In the embodiments of this specification, a target display strategy corresponding to the current speed range to which the vehicle's current speed belongs can be determined based on the vehicle's current speed. Different speed ranges correspond to different display strategies. The current content of the target information to be displayed, as indicated by the target display strategy, can be retrieved and the head-up display can be controlled to display the current content. As can be seen, this solution enables real-time switching to the target display strategy for the corresponding speed range as the vehicle's current speed changes between speed ranges, and accordingly adjusts the information displayed on the head-up display indicated by the target display strategy, thereby ensuring that the currently displayed information matches the driving scenario requirements corresponding to the speed range to which the current speed belongs.

[0024] A 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 instrument panel or device screen.

[0025] In current vehicle head-up display applications, the display content is single and cannot meet the user's display needs 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 range to which the speed belongs is determined according to the current driving speed of the vehicle, and different speed ranges 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 method for controlling 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 illustrating the correspondence between speed intervals, display strategies, and information to be displayed, according to an exemplary embodiment of this specification. The correspondence between speed intervals, display strategies, and information to be displayed can be pre-set. Different speed intervals correspond to different display strategies. A speed interval can be the union of multiple non-contiguous speed sub-intervals. For example, the union of different speed sub-intervals corresponding to the same display strategy can be considered the same speed interval, and a display strategy can be set for that 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, display strategy 1 is used to indicate that the information to be displayed includes A, and display strategy 2 is used to indicate that the information to be displayed 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 display strategy 3 is completely different from the information 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 level 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 within the speed interval [v1, v2], the head-up display can be controlled to display content A, B, and C; if it is determined that the current speed of the vehicle increases 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 can specifically be the layout, position, font size, font color, animation effect, etc. of the information. For example, Figure 2 As shown, both display strategies 1 and 2 indicate that the information to be displayed includes A (vehicle speed information). This information can be displayed differently on the head-up display under display strategies 1 and 2. For example, display strategy 1 indicates that the vehicle speed information is displayed in a small, light-colored font in the lower left corner of the display area. Display strategy 2, on the other hand, indicates that the vehicle speed information is displayed in a large, bright-colored font in the center of the display area.

[0034] In this embodiment, even if the content of the display information of different display strategies is consistent, by adjusting the style of the display information (such as color, font, and position, etc.), the priority of the information in the current display content can be highlighted or weakened 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 ranges, display strategies, and corresponding information for the dynamic display feature. For example, the user can set a speed range and select the information to be displayed in the head-up display within that speed range. Of course, the manufacturer can also set default speed ranges, display strategies, and corresponding information for different driving scenarios. When the dynamic display feature of the head-up display is enabled, the corresponding information is displayed in different speed ranges according to the manufacturer's default display strategy.

[0036] In one embodiment, the number of times the vehicle's speed switches between different speed zones during a first duration is detected. If the number of times exceeds a threshold, the currently executed target display strategy remains unchanged during a second duration. For example, the vehicle may divide time into time intervals, each consisting of a first duration and a second duration. At the beginning of each first duration, the vehicle may periodically collect the vehicle's current speed and determine whether the speed zone to which the currently collected vehicle speed belongs differs from the speed zone to which the previously collected vehicle speed belongs. If so, the number of switches is accumulated until the end of the first duration, and a determination is made as to whether the accumulated total number of switches exceeds a threshold. If the number of switches exceeds the threshold, the currently executed target display strategy remains unchanged during the second duration. For example, if the number of switches exceeds the threshold, even though the vehicle's current speed switches to another speed zone during the second duration, the currently executed target display strategy may be prohibited from switching to another display strategy corresponding to the other speed zone. If the number of switches is less than the threshold, in response to detecting that the vehicle's speed switches to another speed zone during the second duration, the display strategy corresponding to the other speed zone is displayed.

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

[0038] In one embodiment, in different display strategies corresponding to various speed intervals below a preset speed threshold, the amount of information to be displayed indicated by each display strategy is positively correlated with the speed of the speed interval corresponding to the display strategy. And / or, in different display strategies corresponding to various speed intervals not below the preset speed threshold, the amount of information to be displayed indicated by each display strategy is negatively correlated with the speed of the speed interval corresponding to the display strategy. The preset speed threshold can be set to 80 km / h, which can divide the vehicle's driving scene 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 as the vehicle speed increases, so that the driver can obtain more information as the speed increases. For high-speed driving scenes, the amount of information to be displayed decreases as the vehicle speed increases, so that as the speed increases, the information is continuously simplified, the driver only focuses on key information, and the driver is prevented from being distracted. 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 can be different information objects such as vehicle speed information, fuel level information, and warning information, and the number of information to be displayed can 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] below 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 below 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 vehicle's current speed is less than a first speed threshold, a first display strategy is determined as the target display strategy. The information to be displayed as indicated by the first display strategy includes information about the vehicle's surroundings and / or first basic driving information. When the vehicle's current speed is not less than the first speed threshold, a second display strategy is determined as the target display strategy. The information to be displayed as indicated by the second display strategy includes second basic driving information. When the current speed is less than the first speed threshold, the driver needs to pay more attention to the vehicle's surroundings. Therefore, the information to be displayed as indicated by the first display strategy includes information about the vehicle's surroundings. In this case, the information about the vehicle's surroundings can be displayed in a heads-up display, helping the driver make quick decisions without looking down and avoiding the need to frequently check the rearview mirror. When the current speed is not less than the first speed threshold, the information to be displayed as indicated by the second display strategy includes the second basic driving information but does not include information about the vehicle's surroundings. This allows the driver to focus more on the road conditions and vehicle speed ahead, avoiding the distraction of frequently popping up information about the vehicle's surroundings.

[0040] The vehicle's surrounding environment information may include information about obstacles around the vehicle, and the obstacles 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. It 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. It 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. 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 the obstacle information around the vehicle. Figure 3 As shown, Figure 3This specification illustrates a flowchart for determining a target display strategy based on an exemplary embodiment. After the vehicle computer is started, it can be determined whether the dynamic display function is enabled. If the dynamic display function is not enabled, the head-up display can be controlled to display initialization information. If the dynamic display function is enabled, it can be determined whether the vehicle's current speed is less than a first speed threshold. If the vehicle's current speed is less than the first speed threshold, a first display strategy can be determined as the target display strategy, with the information to be displayed indicated by the first display strategy including obstacle information around the vehicle and / or first basic driving information. Specifically, it is determined whether there are obstacles around the vehicle. If there are obstacles, the information to be displayed indicated by the first display strategy may include only obstacle information around the vehicle, or may include both obstacle information around the vehicle and first basic driving information. If there are no obstacles, the information to be displayed indicated by the first display strategy may include only the first basic driving information. If the vehicle's current speed is not less than the first speed threshold, a second display strategy can be determined as the target display strategy, with the information to be displayed indicated by the second display strategy including second basic driving information.

[0043] In one embodiment, the 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 illustrates another flow chart for determining a target display strategy based on an exemplary embodiment. When the vehicle computer is powered on, a determination is made as to whether the dynamic display function is enabled. If not, the head-up display may be controlled to display initialization information. If the dynamic display function is enabled, a determination is made as to whether the vehicle's current speed is less than a second speed threshold. If so, 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 first basic driving sub-information. Specifically, a determination is made as to whether there are obstacles around the vehicle. If so, the information to be displayed indicated by the first display sub-strategy may include only obstacle information around the vehicle, or may include both obstacle information around the vehicle and the first basic driving sub-information. If no obstacles are present, the information to be displayed indicated by the first display sub-strategy may include only the first basic driving sub-information. If the vehicle's current speed 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. 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, a determination is made as to whether there are obstacles around the vehicle. If an obstacle is present, the information to be displayed indicated by the second display sub-strategy may include only the obstacle information around the vehicle, or may include the obstacle information around the vehicle and the second basic driving sub-information. If no obstacle is present, the second display sub-strategy may include only the second basic driving sub-information. If the vehicle's current driving speed 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 can be smaller 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 level information. This increases the amount of information displayed when the vehicle transitions from low to medium speed, allowing the driver to 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, if Figure 5 As shown, Figure 5This is a hardware diagram of a method for controlling the head-up display to display information, as 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 based on the current driving speed. For the target information to be displayed indicated by the target display strategy, the current content of the target information to be displayed is obtained from the camera, radar or other modules, and the head-up display is controlled to display the current content. Of course, the motor can also be controlled to project the content to different locations, or the head-up display can be controlled 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.
