Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

FIG. 1 is a flowchart of a method for adjusting parameters of a head-up display provided by an embodiment of the present application. Referring to Figure 1, this embodiment includes:

Step 101 , obtain the identity information of the driver of the target vehicle.

The driver's identity information is information used to uniquely identify the driver, such as the driver's face image, the driver's fingerprint information, and iris information.

For example, in the implementation, the camera installed on the A-pillar on the main driver's side (not limited to this position) can take pictures of the driver's face on the main driver's seat, and then collect the driver's face in the main driver's seat. face information, and obtain the driver's identity information based on the face information. Alternatively, the fingerprint information of the driver on the main driver's seat can be obtained through the fingerprint sensor installed on the target vehicle, thereby obtaining the identity information of the driver.

Step 102 , according to the driver's identity information, in the pre-stored correspondence between the identity information, the HUD parameters of the head-up display, and the parameter values, determine the HUD parameters to be adjusted and the corresponding parameter values.

The HUD parameters include at least one of height, brightness, adjustment mode, and display content, and the display content includes a display theme, vehicle speed information, and navigation information.

In implementation, a face image of the driver is acquired, and the similarity between the face image and a plurality of pre-stored face images is calculated. When there is a similarity greater than a preset value among the plurality of similarities, the driver has used the target vehicle before, and step 102 is executed. When there is no similarity greater than the preset value among the multiple similarities, the driver has not used the target vehicle, and the HUD parameter setting interface can be displayed on the display of the target vehicle. After the driver sets the HUD parameters and corresponding parameter values on the HUD parameter setting interface, the driver's face image, the HUD parameters and parameter values adjusted by the driver are stored correspondingly.

Alternatively, the fingerprint information of the driver may also be acquired, and the similarity between the fingerprint information of the driver and a plurality of pre-stored fingerprint information may be calculated. When there is a similarity greater than a preset value among the plurality of similarities, the driver has used the target vehicle before, and step 102 is executed. When there is no similarity greater than the preset value among the multiple similarities, the driver has not used the target vehicle, and the HUD parameter setting interface can be displayed on the display of the target vehicle. After the driver sets the HUD parameters and corresponding parameter values on the HUD parameter setting interface, the driver's fingerprint information, the set HUD parameters and the parameter values are stored correspondingly. The driver's identity information can be stored in the target vehicle or in other storage devices capable of data interaction with the target vehicle.

It should be noted that, in the above process, the parameter to be adjusted and the parameter value corresponding to the parameter are associated with the driver's identity information, and the driver's unadjusted parameter and the default value corresponding to the parameter are not associated with the driver. In this way, the unadjusted parameter and the default value corresponding to the parameter need not be stored repeatedly, saving storage space.

For example, the correspondence between pre-stored identity information, HUD parameters of the head-up display, and parameter values is shown in Table 1:

Table 1

身份信息Identity Information	抬头显示器HUD参数Head-up display HUD parameters	参数值parameter value
小王little king	高度high	20cm20cm
小李Xiao Li	调整模式adjustment mode	第一调整模式first adjustment mode
小张Xiao Zhang	显示内容Display content	车辆的速度the speed of the vehicle

Optionally, when the driver has used the target vehicle but has not adjusted the HUD of the target vehicle, only the driver's face image or fingerprint information may be stored, or the driver's face image may not be stored. Or fingerprint information is stored.

Step 103: Adjust the HUD parameters of the target vehicle according to the HUD parameters to be adjusted and the corresponding parameter values.

Among them, if it is determined according to the driver's identity information that the HUD parameter to be adjusted is the image display height of the HUD, then the corresponding parameter value is the image display height value. The image display height can be adjusted.

For example, Mr. Chen lent his car to a friend a few days ago, and the friend reset the HUD parameters. After Mr. Chen gets his car and sits in the driver's seat to start the car, the car will obtain the identity information of Mr. Chen, and adjust the HUD parameters of the car according to the identity information of Mr. Chen. During this process, Mr. Chen does not need to perform any adjustment operations, and the car can automatically adjust the HUD display content to the most suitable display effect for Mr. Chen.

In another example, Mr. Li's family needed to drive out of town. After the car starts, the car recognizes the facial information of Mr. Li in the driving position, automatically determines the HUD parameters that need to be adjusted and the corresponding parameter values, and adjusts the HUD parameters of the car based on the HUD parameters that need to be adjusted and the corresponding parameter values. . Due to the long distance, after four hours of continuous driving, Mr. Li felt very tired. Mr. Li suggested that his wife should drive the car. After swapping places, Mr. Li's wife drove off. At this time, the car obtains the identity information of Mr. Li's wife, and adjusts the HUD parameters of the car again according to the identity information of Mr. Li's wife.

In the technical solution provided by the embodiment of the present application, the target vehicle can obtain the identity information of the driver of the target vehicle, determine the HUD parameters and corresponding parameter values that match the driver's identity information, and then according to the determined HUD The parameters and corresponding parameter values automatically adjust the HUD parameters of the target vehicle, so that when multiple people use the same target vehicle, the driver does not need to adjust the HUD parameters of the target vehicle frequently, which brings convenience to the driver.

Optionally, the target vehicle can periodically obtain the driver's eye position information; when it is detected that the human eye position information changes, in the corresponding relationship between the pre-stored human eye position information and the image display height value of the HUD, Determine the target image display height value of the HUD; adjust the image display height of the HUD of the target vehicle according to the target image display height value of the HUD.

In the implementation, the camera installed on the A-pillar on the main driver's side (not limited to this position) periodically collects the driver's face image, and stores the obtained human eye position information. For example, when it is detected that the change of the human eye position information stored at the last time point and the human eye position information stored at the current time point is greater than the preset condition, it is determined that the driver's eye position has changed, and the last time point is changed. The stored human eye position information is taken as the human eye position information before the change, and the human eye position information stored at the current time point or the human eye position information stored at a certain time point after the current time point is taken as the changed human eye position information, The change between the human eye position stored at a certain time point after the current time point and the human eye position information stored at the current time point is less than a preset condition. Then, according to the changed human eye position information, in the corresponding relationship between the human eye position information pre-stored by the target vehicle and the image display height value of the HUD, the target image display height value of the HUD is obtained; according to the HUD target image display height value, Adjust the image display height of the HUD of the target vehicle.

It should be noted that, after the HUD parameters of the target vehicle are adjusted based on the driver's identity information, the driver's eye position information can be periodically obtained. When it is detected that the driver's eye position information changes, the HUD's image display height is adjusted according to the changed human eye position information, and the image display height value corresponding to the identity information is replaced by the image display height value. When the driver's identity information is not stored in the target vehicle, the image display height value obtained according to the human eye position information is not stored.

Optionally, obtain the human eye position information before the change and the adjustment mode of the HUD of the target vehicle; determine the height difference of the human eye position before and after the change according to the human eye position information after the change and the human eye position information before the change; If the eye position height difference is greater than the first threshold corresponding to the adjustment mode, then according to the changed human eye position information, the target image display of the HUD is determined from the corresponding relationship between the human eye position information stored in the target vehicle and the image display height value of the HUD height value.

The adjustment mode of the HUD is determined based on the positional sensitivity of the human eye to the displayed image of the HUD. For example, it can be divided into a first adjustment mode, a second adjustment mode and a third adjustment mode, and from the first adjustment mode to the third adjustment mode , the sensitivity of the human eye to the displayed image of the HUD gradually decreases. The first threshold value is a preset value corresponding to the adjustment mode in the target vehicle. For example, when corresponding to the above-mentioned first adjustment mode, the first threshold value may be the first preset value; when corresponding to the above-mentioned second adjustment mode, The first threshold may be a second preset value; when corresponding to the third adjustment mode, the first threshold may be a third preset value, and the first preset value is greater than the second preset value, and the second preset value is greater than The third preset value.

In the implementation, when the adjustment mode of the HUD is the first adjustment mode, if the height difference between the positions of the human eyes before and after the change is greater than the first preset value, the human eye position information after the change is pre-stored in the target vehicle. In the corresponding relationship between the eye position information and the image display height value of the HUD, the target image display height value of the HUD is obtained, and based on the target image display height value, the image display height of the HUD of the target vehicle is adjusted; If the height difference between the eye positions is smaller than the first preset value, the image display height of the HUD is not adjusted. When the adjustment mode of the HUD is the second adjustment mode, if the position difference before and after the change of the human eye is greater than the second preset value, then according to the changed human eye position information, the pre-stored eye position information and the HUD image are displayed. In the corresponding relationship of the height values, obtain the display height value of the target image of the HUD, and adjust the image display height of the HUD of the target vehicle based on the display height value of the target image; If the value is set, the display height of the HUD image will not be adjusted. When the adjustment mode of the HUD is the third adjustment mode, if the height difference between the human eye position before and after the change is greater than the third preset value, then according to the changed human eye position information, the pre-stored human eye position information and the HUD image In the corresponding relationship of the display height value, the display height value of the target image of the HUD is obtained, and based on the display height value of the target image, the image display height of the HUD of the target vehicle is adjusted; If the preset value is set, the display height of the HUD image will not be adjusted. It should be noted that the driver adjusts the height and angle of the main driver's seat, resulting in a change in the position of the driver, and further changes in the position information of the driver's human eyes. If the position difference before and after the change of the human eye is smaller than the preset value corresponding to the adjustment mode, the image display height value of the HUD is not adjusted, that is, the image display height value of the HUD is no longer obtained according to the position information after the human eye change. Optionally, collect the current environment brightness of the target vehicle and the last collected environment brightness; when the difference between the current environment brightness and the last collected environment brightness is greater than the preset value, according to the current environment brightness, from the stored environment brightness In the corresponding relationship with the image display brightness value of the HUD, the target image display brightness value of the HUD is obtained; based on the HUD target image display brightness value, the image display brightness of the HUD of the target vehicle is adjusted. When the difference between the current ambient brightness and the last collected ambient brightness is less than the preset value, the brightness of the HUD is not adjusted.

Wherein, an ambient light sensor may be installed in the target vehicle, and then the ambient brightness in the target vehicle may be acquired through the ambient light sensor.

In implementation, the ambient brightness in the target vehicle is periodically acquired and stored in the target vehicle. When it is detected that the difference between the current ambient brightness of the target vehicle and the last collected ambient brightness is greater than the preset value, obtain the brightness value of the HUD according to the ambient brightness and the correspondence between the pre-stored ambient brightness and the brightness value of the HUD; Adjust the brightness of the HUD based on the brightness value of the HUD.

It should be noted that when the driver enters the identity information for the first time and adjusts the HUD parameters, if there is HUD brightness in the HUD parameters adjusted by the driver, the ambient light sensor is used to collect the current ambient brightness in the target vehicle, and the target vehicle The brightness value of the current ambient brightness is stored correspondingly with the current brightness value of the HUD. When the driver's identity information is obtained again, the target vehicle will first adjust the brightness of the HUD to the brightness value of the HUD corresponding to the identity information (that is, the stored brightness value of the HUD), and then the ambient light sensor will collect the target vehicle's brightness. The brightness value of the current ambient brightness, and the brightness value of the ambient brightness stored in the target vehicle is obtained at the same time. When the brightness value of the stored ambient brightness is greater than the brightness value of the current ambient brightness, the target vehicle will automatically reduce the brightness value of the HUD; when the brightness value of the stored ambient brightness is less than the brightness value of the current ambient brightness, the target vehicle will automatically increase the brightness of the HUD value.

In the embodiment of the present application, the target vehicle can automatically adjust the brightness of the HUD according to the ambient brightness in the vehicle, without requiring the driver to manually adjust the brightness of the HUD, which improves the driving experience.

Optionally, based on the driver's identity information, the personalized parameter to be adjusted and the corresponding parameter value are determined from the pre-stored correspondence between the driver's identity information, the personalized parameter and the parameter value, and the personalized parameter includes the seat. At least one of the height and angle of the seat, the angle of the rear-view mirror, the display content (HMI) of the information display screen, and the display content of the instrument panel; based on the personalization parameters and the corresponding target parameter values, the personalization of the target vehicle parameters are adjusted.

In the implementation, the driver's identity information is collected through the information collection device installed on the target vehicle to obtain the driver's identity information. According to the driver's identity information and the corresponding relationship between the driver's identity information, personalized parameters and parameter values pre-stored in the target vehicle, the personalized parameters to be adjusted and the corresponding target parameter values are determined. In the embodiment of the present application, the target vehicle can obtain the identity information of the driver of the target vehicle, and determine the personalized parameter and corresponding parameter value corresponding to the driver's identity information, and then the target vehicle can determine the personalized parameter and corresponding parameter value according to the personalized parameter and corresponding parameter value. The target parameter value automatically adjusts the personalized parameters of the target vehicle, and then when multiple drivers use the target vehicle, the driver's preferred personalized parameters and corresponding parameter values can be determined according to the driver's identity information, There is no need for the driver to frequently adjust the personalized parameters of the target vehicle, which further improves the driver's experience.

The embodiment of the present application also provides another method for adjusting parameters of the head-up display, as shown in FIG. 2 , the method includes:

Step 110, obtaining driving information of the target vehicle.

The driving information includes at least one of the driver's identity information, the driver's eye position information, and ambient brightness information.

For example, an information collection device, a face recognition device and an ambient light sensor can be installed on the target vehicle. The information collection device can collect the driver's identity information, the face recognition device can collect the driver's eye position information, and the ambient light sensor can collect Ambient brightness information.

Step 120: Adjust parameters of the head-up display of the target vehicle according to the driving information.

Wherein, the HUD parameter of the head-up display includes at least one of the image display height, the image display brightness, and the display content of the head-up display. The display content of the HUD may include, for example, a display theme, vehicle speed information, and navigation information.

In the head-up display parameter adjustment method provided by the embodiment of the present application, the target vehicle determines the HUD parameters and parameter values that match the driving information by acquiring the driving information, and then adjusts the HUD of the target vehicle according to the determined HUD parameters and the parameter values. The parameters are automatically adjusted, thereby realizing that when multiple personnel use the same target vehicle, the driver does not need to adjust the HUD parameters of the target vehicle frequently, which brings convenience to the driver.

Optionally, when the driving information includes the driver's identity information, as shown in FIG. 3 , the head-up display parameter adjustment method may include:

Step 201, when receiving the HUD parameter adjustment request, control the information collection device of the target vehicle to obtain the driver's identity information.

In the embodiment of the present application, the HUD parameter adjustment request of the head-up display is sent by the driver to request the target vehicle to automatically adjust the HUD parameters.

In implementation, HUD parameter adjustment buttons may be provided on the center console or the information display screen of the target vehicle. When the driver sits on the main driver's seat of the target vehicle and starts the target vehicle, the driver can click the HUD parameter adjustment button, and then the information collection device of the target vehicle will collect the driver's identity information. The driver's identity information may be, for example, facial information (face image), fingerprint information, iris information and other information that uniquely identifies the driver's identity.

The target vehicle or a storage device capable of data interaction with the target vehicle pre-stores the identity information of the driver who has driven the target vehicle. Optionally, after obtaining the driver's identity information in step 201, if the driver's identity information is stored in the target vehicle, then step 202 is performed; if the driver's identity information is not stored in the target vehicle, then the step can be performed. 204.

For example, the target vehicle may acquire a driver's face image, and calculate the similarity between the acquired face image and a plurality of pre-stored face images in the target vehicle. When there is a similarity greater than a preset value among the calculated similarities, it is determined that the driver has used the target vehicle, and step 202 is executed. When there is no similarity greater than a preset value among the plurality of similarities, the driver has not used the target vehicle, it is determined that the driver has not used the target vehicle, and step 204 is executed.

Step 202: Determine the target parameter value corresponding to the identity information based on the stored correspondence between the identity information and the parameter values of the HUD parameters.

The target vehicle or the storage device may pre-store the driver's identity information, the HUD parameters of the head-up display, and the corresponding relationship of the parameter values. Optionally, when the HUD parameter contains multiple parameter contents, if the driver only adjusts some of the parameter contents, and the other parameter contents keep the default values, then the target vehicle can store the above corresponding relationship. The identity information of the driver, all HUD parameters of the target vehicle, and the parameter value corresponding to each HUD parameter are stored in the target vehicle. At this time, the parameter value of the unadjusted HUD parameter is the default value; The identity information, the adjusted HUD parameters, and the parameter value corresponding to each adjusted HUD parameter are stored in the target vehicle. That is to say, the HUD parameters to be adjusted may be all HUD parameters of the target vehicle, or may be only some HUD parameters adjusted by the driver. For example, the correspondence between the driver's identity information pre-stored in the target vehicle, the adjusted HUD parameters of the head-up display, and the parameter values corresponding to each adjusted HUD parameter are shown in Table 1 above.

Step 203: Adjust the parameters of the head-up display of the target vehicle according to the target parameter value.

Among them, if it is determined according to the driver's identity information that the HUD parameter to be adjusted is the image display height of the HUD, then the target parameter value is the image display height value, and according to the determined target image display height value, the image of the HUD of the target vehicle is Adjust the display height.

In some embodiments of the present application, if the HUD parameters determined by the target vehicle that need to be adjusted are only a part of the HUD parameters of the target vehicle, only these HUD parameters are adjusted, and other HUD parameters that do not need to be adjusted are kept by default. set up.

Optionally, the method for adjusting the parameters of the head-up display provided by the embodiment of the present application further includes: acquiring the current parameter value of the HUD parameter of the target vehicle. Wherein, this step may be performed before step 203 . Correspondingly, as shown in FIG. 4 , step 203 may include:

Step 2031 , compare the target parameter value and the current parameter value of the HUD parameter.

By comparing the target parameter value of the HUD parameter with the current parameter value, the HUD parameter to be adjusted can be determined, and the target parameter value of the HUD parameter to be adjusted is different from the current parameter value.

In implementation, generally speaking, the contents included in the HUD parameters of the same target vehicle are fixed, such as image display height, brightness, adjustment mode, and display contents of the HUD. However, the HUD parameters adjusted by different drivers are different. For example, driver Xiao Wang only adjusted the image display height to 20cm, and the parameter values of other HUD parameters remained the default settings; Xiao Zhang only adjusted the display content of the HUD to the vehicle's display content. The parameter values of speed and other HUD parameters remain at their default settings.

In this case, if the target vehicle automatically adjusts each HUD parameter value, many unnecessary steps will be performed, such as the step of adjusting the push-to-display brightness from the default value to the default value. In order to simplify the automatic adjustment operation of the target vehicle, after identifying the driver's identity information, the target parameter value of the HUD parameter stored in the target vehicle can be compared with the current parameter value, and the difference between the target parameter value and the current parameter value can be determined. The HUD parameters are the HUD parameters to be adjusted.

Step 2032: When the target parameter value is different from the current parameter value, adjust the current parameter value of the HUD parameter to the target parameter value.

When the target parameter value is different from the current parameter value, the target vehicle can determine that the HUD parameter corresponding to the parameter value is the HUD parameter to be adjusted. Yes, in this way, the automatic adjustment operation of the HUD parameters of the target vehicle is completed.

Step 204 , when it is determined that the driver's identity information is not stored in the target vehicle, a request for entering the identity information is displayed.

The identity information entry request is used to request to store the driver's identity information. After the target vehicle determines that the driver has not used the target vehicle, the driver may be presented with an identity information entry request. The identity information input request can be displayed in various forms, for example, it can be displayed on the information display screen of the target vehicle, or it can be played in the form of sound through the speaker of the target vehicle.

According to the driver's response to the identity information entry request, one of the following

steps

2041 and 2042 is performed. Step 2041 and step 2042 are shown in FIG. 5 .

Step 2041, when the confirmation entry instruction is received, the identity information is stored, and the first prompt message is sent out.

The first prompt information is used to instruct the driver to customize HUD parameters.

In implementation, when the target vehicle receives the confirmation entry instruction sent by the driver, the driver's identity information is stored in the target vehicle or the storage device, wherein the confirmation entry instruction is used to instruct the driver to agree to enter the identity information. Afterwards, the target vehicle sends first prompt information to the driver. The display form of the first prompt information can be, for example, a setting interface for displaying HUD parameters on the information display screen, and the driver inputs his preferred HUD parameter configuration information in the setting interface. After the driver has set the HUD parameters and corresponding parameter values on the HUD parameter setting interface, the driver's identity information, HUD parameters and parameter values are stored correspondingly.

In other embodiments, the target vehicle may also only associate the HUD parameter adjusted by the driver and the parameter value corresponding to the HUD parameter with the driver's identity information, but not the HUD parameter not adjusted by the driver and the HUD parameter The corresponding default parameter value is associated with the driver's identity information, so that the target vehicle does not need to repeatedly store the driver's unadjusted HUD parameter and the default parameter value corresponding to the HUD parameter, which saves storage space.

Optionally, if the driver has used the target vehicle but has not adjusted the HUD parameters of the target vehicle, the target vehicle can only store the driver's identity information without storing the HUD parameters and parameter values; The driver's identity information may not be stored.

Step 2042, when receiving the input rejection instruction, the parameter value of the HUD parameter of the control target vehicle is restored to the default value.

In an implementation, when the target vehicle receives a refusal to enter the entry command issued by the driver, the driver's identity information is not stored, wherein the refusal to enter the entry instruction is used to instruct the driver to refuse to enter the identity information. After that, the target vehicle will adjust the parameter values of all HUD parameters to the default values, that is, return to the default settings. At this time, the driver can choose to manually adjust the parameter values of the HUD parameters of the target vehicle.

Optionally, in this embodiment of the present application, based on the driver's identity information, the parameter value corresponding to each personalized parameter may be determined from the stored correspondence between the driver's identity information, personalized parameters, and parameter values. , the personalized parameters include at least one of the height and angle of the seat, the angle of the rearview mirror, the display content of the information display (HMI) and the display content of the instrument panel; based on the personalized parameters and the corresponding The target parameter value of the target vehicle is adjusted to adjust the personalized parameters of the target vehicle.

In the implementation, the driver's identity information is collected through the information collection device installed on the target vehicle to obtain the driver's identity information. The target parameter value corresponding to each personalized parameter is determined according to the driver's identity information and the correspondence between the driver's identity information, personalized parameters and parameter values pre-stored in the target vehicle. In the embodiment of the present application, the target vehicle can obtain the identity information of the driver of the target vehicle, determine the personalized parameters and corresponding parameter values corresponding to the driver's identity information, and then the target vehicle can determine the target vehicle according to the target corresponding to each personalized parameter. The parameter value automatically adjusts the personalized parameters of the target vehicle, and then in the case of multiple drivers using the target vehicle, the personalized parameters preferred by the driver and the corresponding parameter values can be determined according to the driver's identity information. The driver is required to frequently adjust the personalized parameters of the target vehicle, which further improves the driver's experience.

In some embodiments of the present application, the target vehicle can also identify only the personalized parameters that need to be adjusted according to the driver's identity information, and adjust these personalized parameters that need to be adjusted, while other personalized parameters that do not need to be adjusted can be adjusted. , keep the default settings.

Optionally, the target vehicle can also obtain the current parameter value of each personalized parameter of the target vehicle; compare the target parameter value and the current parameter value of each personalized parameter, determine the personalized parameter to be adjusted, and the personalized parameter to be adjusted. The target parameter value of the parameter is different from the current parameter value; adjust the current parameter value of the HUD parameter to be adjusted to the target parameter value.

In the embodiment of the present application, when the driver adjusts the height and angle of the main driver's seat, the position of the driver's human eyes is easily changed, which makes it difficult for the driver to clearly see the displayed image of the HUD. Therefore, the target vehicle can also automatically adjust the HUD parameters and their parameter values during the driving process, thereby improving the driving comfort of the driver.

Optionally, when the driving information includes the driver's eye position information, in the head-up display parameter adjustment method, as shown in FIG. 6 , step 120 may include:

Step 121 , based on the stored correspondence between the human eye position information and the image display height value of the head-up display, determine the target image display height value corresponding to the current human eye position information.

In some embodiments, the camera installed on the A-pillar on the main driver's side (not limited to this position) periodically collects the driver's face image, and analyzes the face image to obtain the human eye position information, and then obtains the image of the driver's face. The obtained human eye position information is stored in the target vehicle or other storage device. For example, when it is detected that the change of the human eye position information stored at the last time point and the human eye position information stored at the current time point is greater than the preset condition, it is determined that the driver's eye position has changed, and the last time point is changed. The stored human eye position information is taken as the human eye position information before the change, and the human eye position information stored at the current time point is taken as the changed human eye position information. Then, according to the changed human eye position information, the target image display height value of the HUD is obtained from the corresponding relationship between the human eye position information pre-stored by the target vehicle and the image display height value of the HUD.

Optionally, as shown in FIG. 7 , step 121 may include:

Step 1211 , when it is detected that the driver's eye position information changes, according to the current human eye position information and the human eye position information before the change, determine the height difference of the human eye position before and after the change.

In the implementation, according to the changed human eye position information and the human eye position information before the change, the height difference of the human eye position before and after the change is determined, and then the first adjustment threshold is obtained, and the first adjustment threshold is the driver according to the head-up display. Displays the image's position sensitivity setting threshold. As the sensitivity of the human eye to the position of the displayed image of the HUD increases from high to low, the value of the first adjustment threshold gradually decreases.

In some embodiments of the present application, in order of the sensitivity of the human eye to the displayed image of the HUD from high to low, the parameter setting item of the target vehicle is configured with a first adjustment mode, a second adjustment mode and a third adjustment mode , the first adjustment thresholds corresponding to the three adjustment modes are respectively a first value, a second value and a third value, and the first value is greater than the second value, and the second value is greater than the third value. If the driver selects the second adjustment mode according to his own situation, then in the subsequent judgment step, the target vehicle judges whether the height difference between the positions of the human eyes before and after the change is greater than the second value.

Exemplarily, since the human eye has the highest sensitivity to the position of the displayed image of the HUD in the first adjustment mode, which means that the human eye can feel the position change of the displayed image of the HUD very keenly, in order to prevent the image display height of the HUD from being adjusted frequently. To cause visual disturbance to the driver, the first value corresponding to the first adjustment mode can be set slightly larger, such as 6cm, so that the image display height of the HUD will not change frequently and affect the safe driving of the target vehicle. In the second adjustment mode, the position sensitivity of the human eye to the displayed image of the HUD is medium, which means that the human eye can feel the position change of the displayed image of the HUD more acutely. In order to avoid visual disturbance to the operator, the second value corresponding to the second adjustment mode can be set to be smaller than the first value, for example, 4cm. Because the human eye has the lowest sensitivity to the position of the displayed image of the HUD in the third adjustment mode, which means that the human eye is relatively slow to respond to the position change of the displayed image of the HUD. At this time, the third value corresponding to the third adjustment mode can be set to Smaller than the second value, eg 2cm.

Step 1212, when the height difference between the human eye positions is greater than the first adjustment threshold, determine the target image display height value from the corresponding relationship between the human eye position information and the image display height value of the head-up display according to the current human eye position information.

In implementation, when the adjustment mode of the HUD is the first adjustment mode, if the height difference between the positions of the human eyes before and after the change is greater than the first value, then according to the changed human eye position information, the pre-stored human eye position information and the HUD In the corresponding relationship of the image display height value of the HUD, the target image display height value of the HUD is obtained, and based on the target image display height value, the image display height of the HUD of the target vehicle is adjusted; if the height difference of the human eye position before and after the change is less than For the first value, the display height of the HUD image is not adjusted. When the adjustment mode of the HUD is the second adjustment mode, if the position difference before and after the change of the human eye is greater than the second value, the height value is displayed in the pre-stored eye position information and the image of the HUD according to the changed human eye position information. In the corresponding relationship of , obtain the display height value of the target image of the HUD, and adjust the image display height of the HUD of the target vehicle based on the display height value of the target image; if the height difference of the human eye position before and after the change is less than the second value, then The image display height of the HUD is not adjusted. When the adjustment mode of the HUD is the third adjustment mode, if the height difference between the human eye position before and after the change is greater than the third value, then according to the changed human eye position information, the pre-stored human eye position information and the image display height of the HUD are displayed. In the corresponding relationship of the values, the display height value of the target image of the HUD is obtained, and based on the display height value of the target image, the image display height of the HUD of the target vehicle is adjusted; if the height difference of the human eye position before and after the change is less than the third value, The display height of the HUD image is not adjusted.

Step 122: Adjust the image display height of the HUD of the target vehicle according to the target image display height value.

After acquiring the display height value of the target image, you can compare the display height value of the current image with the display height value of the target image, and when the two are different, adjust the display height value of the current image to the display height value of the target image.

In the embodiment of the present application, during the driving of the target vehicle, the ambient light may change, so that the display content of the HUD cannot be clearly seen by human eyes, and even the driving is affected. For example, the target vehicle may suddenly enter a dark environment such as a tunnel. If the display brightness of the HUD is too large, it will easily stimulate the driver's eyes and affect safe driving. Therefore, the target vehicle can also automatically adjust the image display brightness of the HUD during driving, thereby ensuring driving safety.

Optionally, when the driving information includes ambient brightness information, in the head-up display parameter adjustment method, as shown in FIG. 8 , step 120 may include:

Step 123 , based on the stored correspondence between the ambient brightness and the image display brightness value of the head-up display, determine the target image display brightness value corresponding to the current ambient brightness.

In implementation, the ambient light sensor can acquire the ambient brightness in the target vehicle in real time or periodically, and store the acquired ambient brightness in the target vehicle or a storage device. When it is detected that the change of the ambient brightness stored at the last time point and the ambient brightness stored at the current time point is greater than the preset condition, it is determined that the ambient brightness has changed, and at this time, the ambient brightness stored at the last time point is used as the environment before the change. Brightness, calculate the difference between the current ambient brightness and the ambient brightness before the change, so as to determine the ambient brightness difference before and after the change.

Step 124 , when the ambient brightness difference is greater than the second adjustment threshold, determine the target image display brightness value from the corresponding relationship between the ambient brightness and the image display brightness value of the head-up display according to the current ambient brightness.

The second adjustment threshold is a threshold set by the driver according to the brightness sensitivity of the displayed image of the head-up display. The setting method of the second adjustment threshold is similar to the setting method of the first adjustment threshold, and both can be set by the driver according to his own situation.

In some embodiments, the target vehicle or the storage device pre-stores the corresponding relationship between the ambient brightness and the image display brightness value of the HUD. When it is detected that the ambient brightness difference is greater than the second adjustment threshold, the image display brightness based on the ambient brightness and the HUD is detected. The corresponding relationship between the values is determined, and the image display brightness value of the HUD corresponding to the current ambient brightness is determined; based on the determined HUD image display brightness value, the image display brightness of the HUD of the target vehicle is adjusted.

In some other embodiments, the second adjustment threshold may also be determined according to the driver's identity information. When the driver enters the identity information for the first time and adjusts the HUD parameters, if the HUD parameters adjusted by the driver include the image display brightness, the ambient light sensor is used to collect the current ambient brightness in the target vehicle, and the current environment in the target vehicle is used. The brightness value of the brightness and the current image display brightness value are stored correspondingly, and at this time, the stored brightness value of the current ambient brightness can be used as the second adjustment threshold. When the target vehicle obtains the driver's identity information again, the target vehicle compares the brightness value of the current ambient brightness collected by the ambient light sensor with the second adjustment threshold (ie, the stored brightness value of the current ambient brightness).

If the brightness value of the current ambient brightness is less than the second adjustment threshold, the target vehicle will automatically generate a new image display brightness value of the HUD according to the difference between the brightness value of the current ambient brightness and the second adjustment threshold, and the automatically generated image displays the brightness The value is smaller than the pre-stored target image display brightness value corresponding to the identity information, which is equivalent to the target vehicle actually automatically lowering the HUD image display brightness value. Conversely, if the brightness value of the current ambient brightness is greater than the second adjustment threshold, the image display brightness value of the HUD automatically generated by the target vehicle will be greater than the pre-stored target image display brightness value corresponding to the identity information, that is, the target vehicle will automatically adjust the brightness value. Images with high HUD display brightness values.

Therefore, in the embodiment of the present application, the target vehicle can automatically adjust the image display brightness of the HUD according to the ambient brightness, without requiring the driver to manually adjust, thereby improving the driving experience.
