[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0022] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "multiple" means two or more. In addition, the use of "based on" or "according to" means openness and inclusiveness, because the process, step, calculation or other action "based on" or "according to" one or more conditions or values ​​can be based on additional conditions or beyond values ​​in practice.

[0023] In order to keep the driver's attention and avoid lowering or turning his head during driving, a head-up display (HUD) is usually installed in the vehicle. The HUD projects the vehicle's speed, navigation and other information onto the windshield in front of the driver. However, when the vehicle is driving on a bumpy road (such as a speed bump or a pothole), the HUD display will shake with the vehicle. If the user watches the shaking image for a long time, it is easy to cause visual fatigue to the user, resulting in a poor user experience and increased safety risks.

[0024] In response to the above problems, the present application provides a method for controlling HUD display, which is applied to vehicles. The method includes: obtaining the pitch angle of the vehicle using an on-board sensor; in response to a change in the pitch angle, determining the reverse compensation amount of the HUD screen according to the pitch angle; and adjusting the display position of the HUD screen according to the reverse compensation amount to display the target information of the vehicle. In the case where the pitch angle of the vehicle changes (such as a scene where the vehicle passes through a bumpy road section), the present solution adjusts the display position of the HUD screen by the pitch angle of the vehicle, so that the HUD screen is stably displayed relative to the ground, thereby helping to relieve the user's visual fatigue, improving the user experience, and reducing safety hazards.

[0025] Combined with the following Figure 1 The control method of the HUD display in the embodiment of the present application is described in detail. The control method of the HUD display in the embodiment of the present application can be applied to a vehicle, which can be an electric vehicle, a fuel vehicle, or a hybrid vehicle, etc., and the present application does not make any specific restrictions on this. Figure 1 As shown, the HUD display control method 100 may include steps: S110 to S130.

[0026] In step S110, the pitch angle of the vehicle is acquired using the vehicle-mounted sensor. In this application, the pitch angle of the vehicle may also be referred to as the pitch angle data of the vehicle.

[0027] In the embodiment of the present application, the vehicle-mounted sensor is mainly used to measure the pitch angle of the vehicle. The vehicle-mounted sensor may be an inertial measurement unit (IMU) gyroscope. Of course, the vehicle-mounted sensor may also be other types of sensors capable of measuring the pitch angle of the vehicle, such as an accelerometer or an inclination sensor, etc., and the present application does not impose any specific restrictions on this.

[0028] It should be noted that the pitch angle detection value directly obtained by the vehicle-mounted sensor usually needs to be processed to correct the detection error and improve the detection accuracy. In some implementations, after the pitch angle detection value of the vehicle is obtained, the pitch angle detection value can be multiplied by the pitch angle correction coefficient a to obtain the pitch angle of the vehicle. As an example, the pitch angle of the vehicle is F(A), F(A) = a*A, a is the correction coefficient of the pitch angle (a is a constant), and A is the pitch angle detection value of the vehicle. Among them, a can be set according to demand, and this application does not impose specific restrictions on this.

[0029] The pitch angle of a vehicle may refer to the angle of the vehicle relative to the horizontal ground. If the vehicle is on an uphill road, the vehicle is up, and the pitch angle of the vehicle may be calibrated as a positive angle; if the vehicle is on a downhill road, the vehicle is down, and the pitch angle of the vehicle may be calibrated as a negative angle.

[0030] As an example, assuming that the vehicle pitch angle is F(A), F(A) = a*A. When the vehicle is traveling along a horizontal road, F(A) = 0; when the vehicle is traveling along a downhill road (i.e., the vehicle is facing downward), F(A) < 0; when the vehicle is traveling along an uphill road (i.e., the vehicle is facing upward), F(A) > 0.

[0031] In step S120 , in response to the pitch angle changing, a reverse direction compensation amount of the HUD screen is determined according to the pitch angle.

[0032] It should be understood that the pitch angle of the vehicle is detected in real time. The detection time interval of the pitch angle of the vehicle is determined by the data collection period of the vehicle-mounted sensor, and this application does not impose any specific restrictions on this.

[0033] The pitch angle of the vehicle changes means that the pitch angle of the vehicle at the previous moment is inconsistent with the pitch angle of the vehicle at the current moment (that is, the pitch angle value at the current moment has changed relative to the pitch angle value at the previous moment). The pitch angle in the embodiment of the present application may include the pitch angle of the vehicle at the previous moment and the pitch angle at the current moment.

[0034] In the embodiment of the present application, the reverse direction compensation refers to the adjustment amount of the HUD screen. In some implementations, the reverse direction compensation is associated with one or more of the following vehicle parameters: the pitch angle of the vehicle, the speed of the vehicle, and the acceleration of the vehicle.

[0035] As an example, before determining the reverse direction compensation amount of the HUD screen, the current speed and current acceleration of the vehicle may be obtained first, and then, in response to a change in the pitch angle, the reverse direction compensation amount may be determined based on the pitch angle, the current speed and the current acceleration.

[0036] For example, the reverse direction compensation amount F(B) of the HUD screen in the present embodiment may be:

[0037] F(B)=-1*b(B-B'), B=F(A)=a*A, B'=B*V*a', wherein b is the correction coefficient of the reverse direction compensation (b is a constant), V is the current speed of the vehicle, a' is the current acceleration of the vehicle, a is the correction coefficient of the pitch angle, and A is the pitch angle detection value of the vehicle.

[0038] Further, substituting B and B' into F(B), we obtain: F(B) = -1*b(a*Aa*A*V*a').

[0039] Further, after deformation, we can obtain: F(B)=-1*a*b*A(1-V*a')=a*b*A(V*a'-1).

[0040] In the embodiment of the present application, the reverse direction compensation amount has positive and negative values. When the reverse direction compensation amount is positive, it indicates that the display position of the HUD screen needs to be adjusted downward; when the reverse direction compensation amount is negative, it indicates that the display position of the HUD screen needs to be adjusted upward.

[0041] It should be noted that if the vehicle is on an uphill road, the reverse compensation amount is positive, and the display position of the HUD screen needs to be adjusted downward; if the vehicle is on a downhill road, the reverse compensation amount is negative, and the display position of the HUD screen needs to be adjusted upward. That is, when the vehicle is traveling along a horizontal road, F(B) = 0; when the vehicle is traveling along a downhill road, F(B) < 0; when the vehicle is traveling along an uphill road, F(B) > 0.

[0042] The present application does not impose any specific limitation on the method for detecting the vehicle speed. For example, a wheel speed sensor may be used to detect the vehicle speed; or, in another example, a Hall effect sensor may be used to detect the vehicle speed.

[0043] The present application does not impose any specific restrictions on the method for detecting the vehicle acceleration. For example, a vehicle-mounted three-axis accelerometer may be used to detect the vehicle acceleration; or, as another example, a vehicle-mounted single-axis accelerometer may be used to detect the vehicle acceleration.

[0044] In step S130, the display position of the HUD screen is adjusted according to the reverse direction compensation amount to display the target information of the vehicle.

[0045] In the embodiment of the present application, the target information includes but is not limited to: vehicle speed, navigation and other driving information.

[0046] In the embodiment of the present application, the HUD screen may refer to the display screen projected onto the windshield directly in front of the driver through the HUD optical machine.

[0047] It should be understood that the HUD screen has a display range frame, that is, the display position of the HUD screen has an upward adjustment boundary (that is, the upper boundary of the display range frame) and a downward adjustment boundary (that is, the lower boundary of the display range frame). The upward and downward adjustment of the HUD screen is performed within the range between the upward adjustment boundary and the downward adjustment boundary.

[0048] As an example, adjusting the display position of the HUD screen according to the reverse direction compensation amount includes: obtaining the display range box of the HUD screen; if the reverse direction compensation amount is equal to 0, centering the HUD screen in the display range box; if the reverse direction compensation amount is less than 0, adjusting the HUD screen upward within the display range box; or, if the reverse direction compensation amount is greater than 0, adjusting the HUD screen downward within the display range box.

[0049] Taking into account that the display position of the HUD screen has an adjustment range, if the reverse compensation amount is positive and greater than a certain threshold, the HUD screen will be adjusted downward to the lower adjustment boundary at most; if the reverse compensation amount is negative and less than a certain threshold, the HUD screen will be adjusted upward to the upper adjustment boundary at most.

[0050] As an example, if the reverse direction compensation amount is less than the first threshold, the HUD screen is adjusted upward to the upper boundary of the display range frame; if the reverse direction compensation amount is greater than the second threshold, the HUD screen is adjusted downward to the lower boundary of the display range frame; wherein the first threshold is less than 0, and the first threshold is used to characterize the maximum upward movable amount of the HUD screen; the second threshold is greater than 0, and the second threshold is used to characterize the maximum downward movable amount of the HUD screen. The first threshold and the second threshold can be set according to demand, and this application does not impose specific restrictions on this.

[0051] It should be understood that in the embodiment of the present application, the display range box of the HUD screen can be set to a colorless virtual box, so as to avoid affecting the driver's line of sight.

[0052] As mentioned above, the reverse compensation amount F(B) after deformation is: F(B) = a*b*A(V*a'-1). It can be seen that within the range between the upper adjustment boundary and the lower adjustment boundary, the reverse compensation amount F(B) is positively correlated with the pitch angle (a*A) of the vehicle; within the range between the upper adjustment boundary and the lower adjustment boundary, if V*a'>1, the absolute value of the reverse compensation amount is positively correlated with the product of the current speed and the current acceleration.

[0053] In some implementations, after adjusting the display position of the HUD screen, the method further includes: if the pitch angle does not change, not adjusting the display position of the HUD screen.

[0054] In some implementations, before adjusting the display position of the HUD screen, the method further includes: monitoring the road surface in front of the vehicle; in response to detecting that there is a bumpy road surface in front of the vehicle, turning on a stability adjustment switch of the HUD screen. In some implementations, the stability adjustment switch may be an automatic logic control switch. Of course, the stability adjustment switch may also be a manual button switch.

[0055] It should be noted that the stability adjustment switch of the HUD screen may refer to a switch for adjusting the HUD screen up and down. If the stability adjustment switch is in the off state, the HUD screen cannot be adjusted up and down; if the stability adjustment switch is in the on state, the HUD screen can be adjusted up and down.

[0056] In some implementations, a vehicle-mounted visual sensor may be used to monitor the road surface in front of the vehicle to determine whether there is a bumpy road surface in front of the vehicle. The vehicle-mounted visual sensor may be, for example, a vehicle-mounted camera, and based on image information collected by the vehicle-mounted visual sensor, it may be determined whether there is a bumpy road surface in front of the vehicle.

[0057] The following describes the embodiments of the present application in more detail with reference to specific examples. Figure 2 and Figure 3 It is only to help those skilled in the art understand the embodiments of the present application, rather than to limit the embodiments of the present application to the specific values ​​or specific scenarios illustrated. Those skilled in the art can obviously make various equivalent modifications or changes based on the examples given, and such modifications or changes also fall within the scope of the embodiments of the present application.

[0058] Figure 2 Another HUD display control method provided in an embodiment of the present application includes: Figure 2 In the example, assume that the vehicle pitch angle is F(A), F(A) = a*A, a is the correction coefficient of the pitch angle, and A is the sensor detection value of the vehicle pitch angle. When the vehicle is traveling along a horizontal plane, F(A) = 0; when the vehicle is facing downward, F(A) < 0; when the vehicle is facing upward, F(A) > 0. Assume that the reverse direction compensation amount of the HUD screen is F(B), F(B) = -1*b(B-B'), B = F(A), B' = B*V*a', where b is the correction coefficient of the reverse direction compensation amount, V is the current speed of the vehicle, and a' is the current acceleration of the vehicle. When the vehicle is traveling along a horizontal plane, F(B) = 0; when the vehicle is facing downward, F(B) < 0; when the vehicle is facing upward, F(B) > 0.

[0059] See also Figure 2 When a vehicle is driving on a road, the method for controlling the HUD display may include the following steps: 201 to 206.

[0060] In step 201: when the vehicle is running stably (i.e., the vehicle is running along a horizontal plane), the vehicle body is stable relative to the ground, and the vehicle body pitch angle F(A)=0, at this time F(B)=0, and the HUD screen is displayed in the center of the upper and lower parts within the display range box.

[0061] In step 202: when the vehicle goes down the bridge, the vehicle is at a downward angle relative to the ground. At this time, the pitch angle F(A) is less than 0, and F(B) is less than 0. Within the display range box, the HUD screen display position is adjusted to move upward through the HUD screen display mechanism (such as a HUD optical machine).

[0062] In step 203: when the vehicle passes over the speed bump, the vehicle is at an upward angle relative to the ground, and the pitch angle F(A)>0, and F(B)>0. Within the display range box, the HUD screen display position is adjusted downward by the HUD screen display mechanism.

[0063] In step 204: when the vehicle passes through a pit on the ground, the vehicle is at a downward angle relative to the ground. At this time, the pitch angle F(A) is less than 0, and F(B) is less than 0. Within the display range box, the HUD screen display position is adjusted to move upward through the HUD screen display mechanism.

[0064] In step 205: when the vehicle goes on the bridge, the vehicle is at an upward angle relative to the ground, and the pitch angle F(A)>0, and F(B)>0. Within the display range box, the HUD screen display position is adjusted downward by the HUD screen display mechanism.

[0065] In step 206: when the vehicle is traveling along a horizontal plane, the vehicle body is stable relative to the ground, the vehicle body pitch angle F(A)=0, and at this time F(B)=0, and the HUD screen is displayed in the center of the upper and lower parts within the display range frame.

[0066] It should be noted that Figure 2 The black screen in the figure is the HUD screen to be displayed, and the diagonal background area box is the display range box of the HUD screen. It should be understood that Figure 2 The black screen and the diagonal background area frame in the figure are colors and lines added for the convenience of presentation. In actual applications, the display screen of the HUD screen is transparent, and the target display information in the HUD screen (such as driving information such as vehicle speed or navigation) can be white or other colors (such as green). This application does not impose specific restrictions on this. The diagonal background area frame (i.e., the display range frame of the HUD screen) is a transparent virtual frame. The display range frame of the HUD screen is mainly used to enclose the display range or adjustment range of the HUD screen.

[0067] Figure 3 Another HUD display control method provided in the embodiment of the present application is shown in Figure 3 The HUD display control method may include the following steps: S301 to S304.

[0068] In step S301, it is determined whether the HUD stabilization switch is turned on. If the HUD stabilization switch is turned on, the process jumps to step S302; if the HUD stabilization switch is not turned on, the process jumps to step S303.

[0069] In step S302, the real-time pitch angle of the current vehicle is obtained, and the display position of the HUD is adjusted in real time according to the pitch angle:

[0070] 1) When it is detected that the vehicle body is rising (such as when the vehicle passes over a speed bump), within the display range box, the HUD screen display mechanism adjusts the HUD screen display position downward and jumps to step S304 to achieve the stability of the HUD screen relative to the ground.

[0071] 2) When the vehicle body is detected to be pitching down (such as a scene where the vehicle passes through a pothole), within the display range box, the HUD screen display position is adjusted to move upward through the HUD screen display mechanism, and the process jumps to step S304 to achieve the stability of the HUD screen relative to the ground.

[0072] 3) When it is detected that the vehicle body is stable (such as a scene where the vehicle passes through a horizontal ground), the HUD screen is displayed in the center of the upper and lower parts within the display range frame, and jumps to step S304.

[0073] In step S303, the HUD screen is not compensated.

[0074] In step S304, the HUD screen is displayed within the display range frame.

[0075] It should be understood that the control method of HUD display in the embodiment of the present application can also be applied to the screen display of ARHUD.

[0076] Combination of the above Figures 1 to 3 The method embodiment of the present application is described in detail. Figures 4 to 5 The device embodiment of the present application is described in detail. It should be understood that the description of the method embodiment corresponds to the description of the device embodiment, so the parts not described in detail can refer to the previous method embodiment.
