Description

Technical Field

[0001] This invention relates to vehicle head-up display systems, and more specifically, to a method, system, and readable storage medium for adjusting the parameters of a HUD. Background Technology

[0002] Head-up display (HUD) systems offer convenience to drivers, but different road conditions during driving can cause significant bumps or vibrations, potentially leading to deviations in the position of the HUD's moving mirrors and resulting in errors in the HUD's height parameters. Currently, HUD parameter adjustments are primarily made when the vehicle is stationary, but the parameters of the HUD on the vehicle can change while the vehicle is in motion, causing confusion for the driver.

[0003] Therefore, existing technologies have shortcomings and urgently need improvement. Summary of the Invention

[0004] In view of the above problems, the purpose of this invention is to provide a method, system and readable storage medium for adjusting the parameters of a HUD, which can more conveniently and effectively adjust the parameters of the HUD.

[0005] The first aspect of this invention provides a method for adjusting the parameters of a HUD, comprising:

[0006] Obtain HUD parameter values ​​based on a preset time period;

[0007] The parameter values ​​of the HUD are compared and analyzed with the preset HUD settings to obtain the parameter difference of the HUD;

[0008] Determine whether the parameter difference of the HUD is greater than a preset parameter difference threshold. If so, trigger the parameter adjustment information of the HUD.

[0009] The parameter differences of the HUD are sent to a preset terminal for adjustment;

[0010] The parameter values ​​of the HUD are determined by the rotation angle of the moving mirror.

[0011] This plan also includes:

[0012] Vehicle vibration values ​​are obtained based on preset vibration sensors;

[0013] Determine whether the vehicle vibration value is greater than a preset vibration threshold; if so, trigger the HUD position sensor.

[0014] The position information of the HUD moving mirror is obtained by the HUD position sensor and the preset time period is re-timed.

[0015] This plan also includes:

[0016] When the vehicle vibration value exceeds the preset vibration threshold, the time when the corresponding vehicle vibration value is generated is recorded.

[0017] Vehicle vibration values ​​exceeding the preset vibration threshold are arranged in chronological order, and the time difference between adjacent times is calculated.

[0018] Determine whether the time difference is less than a preset first time difference threshold. If so, trigger the HUD position sensor switch of the vehicle and keep it in continuous working state.

[0019] When the vehicle's HUD position sensor remains continuously operational, it determines whether the time difference between adjacent times is greater than a preset second time threshold. If so, the vehicle's HUD position sensor exits the continuous operational state.

[0020] In this solution, the steps for setting the preset HUD parameter values ​​include:

[0021] The user selects a specific camera angle in the user interface and confirms it.

[0022] The user-selected specific camera angle is sent to a preset storage repository for storage;

[0023] Set the user-selected specific moving mirror angle as the preset HUD setting parameter value.

[0024] This plan also includes:

[0025] Based on preset voice information, the HUD enters the state of setting parameter value adjustment;

[0026] Obtain adjustment instructions from the user;

[0027] Based on the adjustment command information from the user terminal and the preset adjustment coefficient, the rotation angle of the moving mirror corresponding to the adjustment command is obtained;

[0028] Based on the rotation angle of the moving mirror before adjustment, it is determined whether the rotation angle of the moving mirror in the adjustment command is within the preset rotation angle range. If so, the setting parameter value is adjusted according to the adjustment command from the user terminal; otherwise, the user terminal is prompted to re-enter the voice command information.

[0029] This plan also includes:

[0030] Obtain the vehicle's seat height information;

[0031] Based on the height range that the vehicle's seat height falls into, the recommended values ​​for the HUD settings corresponding to the vehicle's seat height are obtained.

[0032] Recommended settings for the HUD are sent to the user's screen for display.

[0033] A second aspect of the present invention provides a parameter adjustment system for a head-up display (HUD), comprising a memory and a processor. The memory stores a parameter adjustment method program for the HUD, which, when executed by the processor, performs the following steps:

[0034] Obtain HUD parameter values ​​based on a preset time period;

[0035] The parameter values ​​of the HUD are compared and analyzed with the preset HUD settings to obtain the parameter difference of the HUD;

[0046] Determine whether the time difference is less than a preset first time difference threshold. If so, trigger the HUD position sensor switch of the vehicle and keep it in continuous working state.

[0047] When the vehicle's HUD position sensor remains continuously operational, it determines whether the time difference between adjacent times is greater than a preset second time threshold. If so, the vehicle's HUD position sensor exits the continuous operational state.

[0048] In this solution, the steps for setting the preset HUD parameter values ​​include:

[0049] The user selects a specific camera angle in the user interface and confirms it.

[0050] The user-selected specific camera angle is sent to a preset storage repository for storage;

[0051] Set the user-selected specific moving mirror angle as the preset HUD setting parameter value.

[0064] Figure 2The flowchart for setting the HUD's configuration parameters is shown;

[0065] Figure 3 A block diagram of a parameter adjustment system for a HUD according to the present invention is shown. Detailed Implementation

[0066] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0067] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0068] Figure 1 A flowchart of a method for adjusting the parameters of a HUD according to the present invention is shown.

[0069] like Figure 1 As shown, this invention discloses a method for adjusting the parameters of a HUD, including:

[0070] S102, Obtain the parameter values ​​of the HUD based on a preset time period;

[0071] S104, compare and analyze the parameter values ​​of the HUD with the preset HUD setting parameter values ​​to obtain the parameter difference of the HUD;

[0072] S106, determine whether the parameter difference of the HUD is greater than the preset parameter difference threshold; if so, trigger the parameter adjustment information of the HUD.

[0073] S108, the parameter difference of the HUD is sent to a preset terminal for adjustment;

[0074] It should be noted that the parameter values ​​of the HUD are determined by the rotation angle of the moving mirror. The setting parameter value of the HUD is the rotation angle of the moving mirror. Let the rotation angle of the moving mirror be A0. The parameter adjustment process of the HUD is the same as the angle adjustment process of the moving mirror. For example, if the preset time period is set to 1 minute, then the position of the HUD moving mirror is detected every 1 minute by a preset HUD position sensor. Let the position of the HUD moving mirror detected by the preset HUD position sensor be A1. Then the parameter difference ΔA = |A1-A0|. If the preset parameter difference threshold is set to A2, then when ΔA>A2, it means that the parameter value of the corresponding HUD needs to be adjusted. When (A1-A0) is positive, the motor for adjusting the moving mirror needs to be adjusted clockwise (or counterclockwise); when (A1-A0) is negative, the motor for adjusting the moving mirror needs to be adjusted counterclockwise (or clockwise).

[0075] According to an embodiment of the present invention, it further includes:

[0076] Vehicle vibration values ​​are obtained based on preset vibration sensors;

[0077] Determine whether the vehicle vibration value is greater than a preset vibration threshold; if so, trigger the HUD position sensor.

[0078] The position information of the HUD moving mirror is obtained by the HUD position sensor and the preset time period is re-timed.

[0079] It should be noted that when the car vibrates, the position of the HUD's moving mirror will also vibrate. The vibration value of the car is detected by a preset vibration sensor and set as B1. If the preset vibration threshold is set to B0, then when B1>B0, the HUD position sensor is activated, regardless of the preset time period, and the preset time period is reset. For example, if the preset time period is set to 1 minute, and at 30 seconds, the preset vibration sensor detects that the car vibration value is greater than the preset vibration threshold, then the HUD position sensor is activated and the cycle time recorded by the preset time sensor is reset to zero, and the preset time period is reset from zero.

[0080] According to an embodiment of the present invention, it further includes:

[0081] When the vehicle vibration value exceeds the preset vibration threshold, the time when the corresponding vehicle vibration value is generated is recorded.

[0082] Vehicle vibration values ​​exceeding the preset vibration threshold are arranged in chronological order, and the time difference between adjacent times is calculated.

[0083] Determine whether the time difference is less than a preset first time difference threshold. If so, trigger the HUD position sensor switch of the vehicle and keep it in continuous working state.

[0084] When the vehicle's HUD position sensor remains continuously operational, it determines whether the time difference between adjacent times is greater than a preset second time threshold. If so, the vehicle's HUD position sensor exits the continuous operational state.

[0085] It should be noted that when the vehicle vibration value exceeds the preset vibration threshold, the time of occurrence of the corresponding vehicle vibration value is recorded, and vehicle vibration values ​​exceeding the preset vibration threshold are collected and numbered according to the order of occurrence, denoted as T. n Where n represents the time number corresponding to the vehicle vibration value exceeding the preset vibration threshold, and the time difference is set as ΔT, then ΔT = T n+1 -T n If the preset first time difference threshold is set to ΔT1, then when ΔT < ΔT1, the HUD position sensor switch of the vehicle is triggered, and the HUD position sensor of the vehicle is kept in a continuous working state. If ΔT > ΔT2, the HUD position sensor of the vehicle exits the continuous working state and enters a periodic working state. Here, ΔT2 represents the preset second time threshold, and ΔT2 > ΔT1. The preset first time difference threshold and the second time difference threshold are set by those skilled in the art.

[0086] Figure 2 The flowchart for setting the HUD configuration parameters is shown.

[0087] like Figure 2 As shown in this embodiment, the steps for setting the preset HUD parameter values ​​include:

[0088] The user selects a specific camera angle in the user interface and confirms it.

[0089] The user-selected specific camera angle is sent to a preset storage repository for storage;

[0090] Set the user-selected specific moving mirror angle as the preset HUD setting parameter value.

[0091] It should be noted that after the user selects a specific moving mirror angle on the user interface and confirms it, the repository stores the specific moving mirror angle and sends it to the circuit board. The circuit board drives the motor to rotate to achieve the moving mirror angle selected by the user, and sets the selected moving mirror angle as the preset HUD setting parameter value.

[0092] Furthermore, given the widespread adoption of mobile applications and the development of smartphones, the phone screen can also serve as the user interface. Different phones can install and register apps, each phone possessing a unique identification code. This code corresponds one-to-one with the HUD's rotation angle. When logging in using that phone, the HUD will adjust to the specific camera angle selected by the user.

[0093] According to an embodiment of the present invention, it further includes:

[0094] Based on preset voice information, the HUD enters the state of setting parameter value adjustment;

[0095] Obtain adjustment instructions from the user;

[0096] Based on the adjustment command information from the user terminal and the preset adjustment coefficient, the rotation angle of the moving mirror corresponding to the adjustment command is obtained;

[0097] Based on the rotation angle of the moving mirror before adjustment, it is determined whether the rotation angle of the moving mirror in the adjustment command is within the preset rotation angle range. If so, the setting parameter value is adjusted according to the adjustment command from the user terminal; otherwise, the user terminal is prompted to re-enter the voice command information.

[0098] It should be noted that when the vehicle is in motion, if the HUD settings need to be adjusted, the HUD settings interface can be activated via a preset voice message. Then, the rotation angle of the moving mirror can be obtained through the adjustment command. The user's adjustment command is divided into multiple command levels, and the preset adjustment coefficient is divided according to the corresponding command level to obtain multiple levels of adjustment coefficients. The rotation angle of the moving mirror is equal to the adjustment command level multiplied by the corresponding adjustment coefficient. Then, it is determined whether the rotation angle of the moving mirror in the adjustment command is within the preset rotation angle range, for example, the preset rotation angle range is between (0, 2) degrees. If the rotation angle of the moving mirror in the adjustment command is within the preset rotation angle range, the corresponding adjustment is made according to the user's voice command; otherwise, the user is prompted to re-enter the voice command.

[0099] According to an embodiment of the present invention, it further includes:

[0100] Obtain the vehicle's seat height information;

[0101] Based on the height range that the vehicle's seat height falls into, the recommended values ​​for the HUD settings corresponding to the vehicle's seat height are obtained.

[0102] Recommended settings for the HUD are sent to the user's screen for display.

[0103] It should be noted that the user needs to adjust the seat before starting the vehicle. After the seat is adjusted, the seat height is recorded, and the recommended setting value of the corresponding HUD is matched according to the corresponding seat height. The recommended setting value of the HUD is then displayed on the user's screen. The seat height range and the corresponding recommended setting value of the HUD are set by those skilled in the art according to actual needs.

[0104] According to an embodiment of the present invention, it further includes:

[0105] Get HUD startup information;

[0106] Set the settings parameter values ​​of the last HUD used when the HUD was last started to the settings parameter values ​​of the current HUD;

[0107] Adjust the vehicle HUD parameter values ​​to the current HUD settings.

[0108] It should be noted that when the HUD is started, if the user has not adjusted the HUD's settings, the HUD will default to the settings of the last used HUD and adjust the current HUD's settings accordingly.

[0109] According to an embodiment of the present invention, it further includes:

[0110] Obtain the cumulative operating time of the HUD position sensor cycle;

[0111] Extract the number of times the HUD parameters were adjusted within the cumulative time of the HUD position sensor's cycle operation;

[0112] The first stable value of the moving mirror is obtained based on the cumulative time of the HUD position sensor's cycle operation and the number of times the HUD parameters are adjusted within the cumulative time of the HUD position sensor's cycle operation.

[0113] Determine whether the first stable value of the moving mirror is greater than a preset first stable threshold; if so, trigger a prompt message.

[0114] The prompt message is sent to the user's screen for display.

[0115] It should be noted that the cumulative time of the HUD position sensor's cyclic operation is set to t. 总 Let m1 be the number of times the HUD parameters are adjusted during the cumulative working time of the HUD position sensor cycle, and Q1 be the first stable value of the moving mirror. Then Q1 = m1 / t 总The smaller Q1 is, the stronger the stability of the corresponding moving mirror during smooth driving. For example, if the preset first stability threshold is q1, then when Q1>q1, a prompt message is triggered, indicating that the user's HUD moving mirror needs maintenance.

[0116] According to an embodiment of the present invention, it further includes:

[0117] The number of times the vehicle vibration value exceeds the preset vibration threshold is obtained;

[0118] Extract the number of HUD parameter adjustments caused by vehicle vibration values ​​exceeding a preset vibration threshold;

[0119] The second stable value of the moving mirror is obtained based on the number of vehicle vibration values ​​exceeding the preset vibration threshold and the number of HUD parameter adjustments caused by vehicle vibration values ​​exceeding the preset vibration threshold.

[0120] Determine whether the second stable value of the moving mirror is greater than the preset second stable threshold. If so, trigger a prompt message.

[0121] The prompt message is sent to the user's screen as a notification.

[0122] It should be noted that the number of vehicle vibration values ​​exceeding the preset vibration threshold is set as m2, the number of HUD parameter adjustments caused by vehicle vibration values ​​exceeding the preset vibration threshold is set as m3, and the second stability value of the moving mirror is set as Q2. Then Q2 = m3 / m2, where the smaller Q2 is, the stronger the stability of the corresponding moving mirror during vibration. The preset second stability threshold is set as q2. When Q2 > q2, a prompt message is triggered, prompting the user that the HUD's moving mirror needs maintenance.

[0124] like Figure 3 As shown, a second aspect of the present invention provides a parameter adjustment system 3 for a HUD, including a memory 31 and a processor 32. The memory stores a parameter adjustment method program for a HUD, which, when executed by the processor, performs the following steps:

The setting parameter value of the HUD is the rotation angle of the moving mirror. Let the rotation angle of the moving mirror be A0.
