[0025] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0026] The following description, with reference to the accompanying drawings, outlines a method, apparatus, vehicle, and storage medium for adjusting the angle of an exterior rearview mirror according to embodiments of this application. Addressing the issues mentioned in the background art, where drivers often find the rearview mirror's field of vision poor, affecting their driving line of sight, and adjustments during driving are risky, requiring adjustments after a driver change, thus reducing user experience and demonstrating low intelligence and practicality, this application provides a method for adjusting the angle of an exterior rearview mirror. This method converts eye angle coordinates into corresponding rearview mirror angle data and compares them with current rearview mirror angle data. Stable eye line coordinates are then converted into corresponding exterior rearview mirror angle positions, automatically adjusting the rearview mirror angle. This not only adapts to the driver's driving needs in different environments but also provides a faster, more efficient, and more comfortable experience. The method allows for more precise adjustment of the exterior rearview mirror angle without safety hazards, enabling users to truly enjoy the safety and comfort brought by the intelligent cockpit system. Therefore, this solves the problems in the related art where drivers often find the rearview mirror's field of vision poor, affecting their driving line of sight, and adjustments during driving are risky, requiring adjustments after a driver change, thus reducing user experience and demonstrating low intelligence and practicality.

[0027] Specifically, Figure 1 This is a flowchart illustrating a method for adjusting the angle of an exterior rearview mirror provided in an embodiment of this application.

[0028] like Figure 1 As shown, the method for adjusting the angle of the exterior rearview mirror includes the following steps:

[0029] In step S101, if it is detected that the driver has fastened his seat belt and has been looking at the exterior rearview mirror for more than a preset time, it is determined that the driver's line of sight meets the preset stability condition, and the vehicle is controlled to enter the automatic adjustment mode of the exterior rearview mirror angle.

[0030] It is understood that the preset time in the embodiments of this application may be, but is not limited to, 3 seconds; the preset stability condition in the embodiments of this application may be the condition that satisfies the driver's eye line stability.

[0031] In actual implementation, this application embodiment can determine that the driver's eye line meets certain stable conditions when it is detected that the driver is wearing a seat belt and is looking at the exterior rearview mirror for ≥3 seconds. That is, after the seat belt is fastened, the range of changes in the collected eye line value is small and stable within a certain calibrated range. When the looking time is ≥3 seconds, the vehicle can be controlled to enter the automatic adjustment mode of the exterior rearview mirror angle.

[0032] This application embodiment can control the vehicle to enter the exterior rearview mirror angle adjustment mode when the driver is wearing a seat belt and looking at the exterior rearview mirror for more than a preset time, thereby providing support for subsequent precise adjustment of the exterior rearview mirror angle and providing the driver with a faster, more efficient and comfortable experience.

[0033] It should be noted that the preset time and preset stability conditions can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0034] Optionally, in one embodiment of this application, before controlling the vehicle to enter the automatic adjustment mode of the exterior rearview mirror angle, the method further includes: controlling the vehicle to stop entering the exterior rearview mirror angle adjustment mode if the driver is not wearing a seat belt or is looking at the exterior rearview mirror for no more than a preset time.

[0035] It is understood that the preset time in the embodiments of this application may be, but is not limited to, 3 seconds.

[0036] As one possible implementation, this application embodiment can control the vehicle not to enter the exterior rearview mirror angle adjustment mode when the driver is not wearing a seat belt or is looking at the exterior rearview mirror for no more than 3 seconds. The automatic adjustment function of the exterior rearview mirror angle will not work, thereby controlling the angle adjustment of the exterior rearview mirror in a targeted manner, thus achieving the convenience of not having to manually adjust it every time the driver.

[0037] It should be noted that the preset time can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0038] Optionally, in one embodiment of this application, the method further includes: receiving a pop-up command from the exterior rearview mirror before controlling the vehicle to enter the automatic adjustment mode of the exterior rearview mirror angle; reminding the driver whether to select the memory mode according to the pop-up command; if the driver selects the memory mode, allowing the vehicle to enter the automatic adjustment mode of the exterior rearview mirror angle while the driver is driving; if the driver does not select the memory mode, allowing the vehicle to enter the automatic adjustment mode of the exterior rearview mirror angle when the vehicle's ignition cycle takes effect.

[0039] It is understood that in this embodiment, the driver must first activate the automatic adjustment function of the exterior rearview mirror before the mirror can automatically adjust its angle according to the eye's line of sight; otherwise, it is in manual adjustment mode. In this embodiment, the exterior rearview mirrors are located on the left and right sides of the front of the car. These mirrors reflect the situation behind, to the sides, and below the car, allowing the driver to indirectly see these areas. Each rearview mirror is equipped with two sets of electric motors and drivers (reduction gears and clutches) to control its vertical and horizontal movement. Typically, vertical movement is controlled by one electric motor, and horizontal tilting movement is controlled by another electric motor; both motors are permanent magnet type.

[0040] In actual implementation, this application embodiment can set a reminder pop-up to increase pop-up prompts and improve user experience. After the automatic adjustment function of the exterior rearview mirror angle is enabled, the vehicle interface pop-up can prompt the user whether to select to remember this function, that is, remind the user that the "automatic adjustment function of the exterior rearview mirror angle" can be remembered after being enabled. This application embodiment can control the vehicle to enter the exterior rearview mirror angle adjustment mode every time the driver uses the vehicle when the driver selects the memory mode, and the automatic adjustment function of the exterior rearview mirror angle will be automatically turned on. This application embodiment can also control the vehicle to enter the exterior rearview mirror angle adjustment mode when the vehicle's ignition cycle is active when the driver does not select the memory mode, and the automatic adjustment function of the exterior rearview mirror angle will only be active in the current ignition cycle (that is: after the vehicle is locked and in sleep mode, the exterior rearview mirror angle position needs to be manually adjusted).

[0041] The embodiments of this application can remind the driver whether to select the memory mode according to the reminder pop-up. Based on different selection results, the purpose of adjusting the angle of the exterior rearview mirror can be achieved, thereby adapting to the driver's driving needs in different environments, and the reliability is strong.

[0042] In step S102, eye angle coordinates that meet preset stability conditions are collected according to the automatic adjustment mode of the external rearview mirror angle.

[0043] It is understood that the automatic adjustment mode of the exterior rearview mirror angle in this application embodiment can be used to adjust the angle of the left and right exterior rearview mirrors of the vehicle; the eye angle coordinates in this application embodiment can be obtained by the in-cabin vision camera, which can collect driver images, field of view monitoring, eye information, etc.

[0044] As one possible implementation, embodiments of this application can collect eye angle coordinates that meet certain stable conditions according to the automatic adjustment mode of the exterior rearview mirror angle. The driver's facial image information is captured by the in-cabin vision camera, and the driver's eye line is extracted based on the facial image information to obtain the eye angle coordinates after the driver's eye line is stabilized. This ensures that the exterior rearview mirror is automatically adjusted subsequently, thereby ensuring the convenience of the driver not having to manually adjust it every time. It also ensures that the exterior rearview mirror angle is adjusted more accurately in the future without any safety hazards, allowing users to truly enjoy the safety and comfort brought by the intelligent cockpit system.

[0045] Optionally, in one embodiment of this application, acquiring eye angle coordinates that meet preset stability conditions includes: acquiring a driver's behavior image; extracting driver's behavior data from the behavior image and obtaining the driver's eye angle based on the behavior data; and determining eye angle coordinates that meet preset stability conditions based on the eye angle.

[0046] It is understood that the behavioral images in the embodiments of this application can be captured by an in-cabin vision camera.

[0047] In actual implementation, the embodiments of this application can collect real-time video of the driver through an in-cabin vision camera, obtain the driver's behavior image from the real-time video, and extract the driver's behavior data from the behavior image. For example, the driver's behavior of looking at the exterior rearview mirror can be extracted, and the driver's eye angle can be obtained based on the behavior. This allows the driver to collect the eye angle coordinates after the driver's eye line stabilizes, thereby ensuring that the exterior rearview mirror angle position is automatically adjusted based on the vision camera.

[0048] This application embodiment can extract driver behavior data from behavioral images, thereby providing support for subsequent precise adjustment of the exterior rearview mirror angle, and further providing drivers with a faster, more efficient and comfortable experience.

[0049] In step S103, the eye angle coordinates are converted into the corresponding exterior rearview mirror angle data, and the corresponding exterior rearview mirror angle data is compared with the current exterior rearview mirror angle data to determine the adjustment angle of the exterior rearview mirror. When the exterior rearview mirror meets the preset adjustment conditions, the exterior rearview mirror is controlled to rotate according to the adjustment angle so that the field of view of the exterior rearview mirror is adjusted to the position corresponding to the driver's eye position.

[0050] It is understood that the eye angle coordinates in this embodiment can be the effective eye coordinates; the user first selects the "Automatic Adjustment of Exterior Rearview Mirror Angle" function in the vehicle settings of the vehicle system, and after turning on the setting, the automatic adjustment function of the exterior rearview mirror angle is enabled; the cockpit domain controller in this embodiment can provide users with infotainment services (video, music, voice, games, Bluetooth, mobile phone interconnection, navigation, telephone, life services, mini-programs) and instrument (vehicle speed, RPM, fuel consumption, driving range, vehicle alarms, etc.) and other functions; the preset adjustment conditions in this embodiment can be the conditions that meet the angle adjustment; the cockpit domain controller eye field algorithm in this embodiment automatically and accurately locates the area of ​​the rearview mirror that the driver is looking at based on the data relationship based on the vehicle body calibration position.

[0051] Specifically, the cockpit domain controller algorithm in this application embodiment can sense the eye angle and convert it into vehicle coordinates based on the vehicle body data. According to the established strategy, it first determines the effective eye coordinates, i.e., the eye angle coordinates, thereby ensuring that the eye coordinate values ​​are calculated using the pre-calibrated correspondence table between eye coordinates and eye line coordinates. The eye angle coordinates are then converted into the corresponding exterior rearview mirror angle data, and the corresponding exterior rearview mirror angle data is compared with the current exterior rearview mirror angle data to determine the adjustment angle.

[0052] Furthermore, in this embodiment of the application, when the exterior rearview mirror meets the condition that the angle can be adjusted, the cockpit domain controller sends the eye coordinate value to the exterior rearview mirror via CAN or other transmission protocol signals, thereby achieving automatic adjustment of the exterior rearview mirror angle position based on the vision camera, ensuring that the exterior rearview mirror is rotated according to the adjustment angle, so that the field of view of the exterior rearview mirror is adjusted to the position corresponding to the driver's eye position.

[0053] This application embodiment can convert the eye angle coordinates into corresponding rearview mirror angle data through an algorithm and compare them with the current rearview mirror angle data. If the triggering condition is met, the left and right rearview mirror angles will be adjusted to a position that adapts to the driver's eye position under the drive of the motor and the driver, providing the driver with a faster, more efficient and comfortable experience. Without causing dangerous driving behavior, it provides users with an intelligent cockpit experience to the greatest extent.

[0054] It should be noted that the preset adjustment conditions can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here. The correspondence between the eye line coordinate value and the rearview mirror angle value can be corrected according to the specific vehicle calibration. Different vehicles have different body parameters, so the correspondence will be different. The embodiments of this application can adjust the data accordingly from the perspective of user experience, and no specific restrictions are imposed here.

[0055] Optionally, in one embodiment of this application, comparing the corresponding exterior rearview mirror angle data with the current exterior rearview mirror angle data to determine the adjustment angle of the exterior rearview mirror includes: obtaining the calibrated standard angle coordinates of the exterior rearview mirror based on the corresponding exterior rearview mirror angle data; obtaining the driver's eye line position based on the current exterior rearview mirror angle data; and matching the calibrated standard angle coordinates of the exterior rearview mirror with the driver's eye line position to determine the adjustment angle of the exterior rearview mirror.

[0056] Specifically, this application embodiment can capture the driver's eye gaze based on an in-cabin vision camera and a domain controller. The coordinates of the eye gaze captured by the in-cabin vision camera are matched with the pre-calibrated standard angle coordinates of the exterior rearview mirror to determine the adjustment angle of the exterior rearview mirror. This ensures that the exterior rearview mirror can be adjusted by rotating under the drive of the motor and driver, adapting to the driver's actual usage needs. It can meet the needs of scenarios where no manual operation is required during driving and multiple people are driving in one vehicle, providing the driver with a safer, more efficient, and convenient experience.

[0057] In this application, since the automatic adjustment range of the exterior rearview mirror angle has been mapped to the eye's field of vision corresponding to the vehicle's rearview mirror, and with the pre-set trigger constraints for automatic adjustment, the entire adjustment process is virtually imperceptible to the user. This application's embodiment can convert eye angle coordinates into corresponding exterior rearview mirror angle data, and compare this data with the current rearview mirror angle data to convert stable eye line coordinates into corresponding exterior rearview mirror angle positions. This provides support for subsequent adjustments to the exterior rearview mirror angle, thereby offering the driver a faster, more efficient, and more comfortable experience, ensuring the intelligence of the angle adjustment.

[0058] This application embodiment can also utilize a T-BOX (Telematics BOX, vehicle electrical component) and a body controller. The T-BOX provides a remote communication interface to the vehicle through functions such as remote wireless communication, GPS (Global Positioning System) satellite positioning, accelerometer sensing, and CAN (Controller Area Network) communication. It offers services including driving data acquisition, driving trajectory recording, vehicle fault monitoring, remote vehicle query and control (locking / unlocking, air conditioning control, window control, engine torque limiting, engine start / stop), driving behavior analysis, and wireless hotspot sharing. The body controller is the core controller for controlling vehicle accessories, achieving functional control of various controllers via CAN / LIN bus or hardwired connections.

[0059] Specifically, it can be combined with Figure 2 As shown, the working principle of the method for adjusting the angle of the exterior rearview mirror in this application is explained in detail with a specific embodiment.

[0060] like Figure 2 As shown, embodiments of this application may include the following steps:

[0061] Step S201: In-cabin vision camera.

[0062] Step S202: Collect the coordinates of the driver's eye gaze.

[0063] Step S203: Domain Controller.

[0064] Step S204: Vehicle ignition.

[0065] Step S205: Determine whether the driver has fastened their seatbelt and whether their gaze time is greater than or equal to 3 seconds. If yes, proceed to step S206; otherwise, proceed to step S207.

[0066] Step S206: Activate the automatic angle adjustment function of the exterior rearview mirror.

[0067] Step S207: The text prompt is "fasten your seatbelt" or "look for less than 3 seconds".

[0068] Step S208: The camera collects eye coordinates and calculates eye coordinate data based on the vehicle body; the front and rear eye coordinate data are compared to confirm the adjustment angle.

[0069] Step S209: Exterior rearview mirror.

[0070] Step S210: Perform angle adjustment.

[0071] The method for adjusting the angle of the exterior rearview mirror according to the embodiments of this application can automatically adjust the angle and position of the exterior rearview mirror using an in-cabin vision camera and a cockpit domain controller as hardware, combined with visual transmission, image perception, signal processing, and artificial intelligence. This automatic adjustment not only adapts to the driver's driving needs in different environments but also provides a faster, more efficient, and more comfortable driving experience. Therefore, it solves the problems in related technologies where, while the vehicle is in motion, the driver easily finds that the rearview mirror's field of vision is poor, affecting the driver's line of sight; adjusting the mirror during driving is dangerous; and the rearview mirror angle needs to be adjusted after a change of driver, reducing user experience and resulting in low intelligence and practicality.

[0072] Next, referring to the accompanying drawings, an adjustment device for the angle of the exterior rearview mirror according to an embodiment of this application is described.

[0074] like Figure 3 As shown, the rearview mirror angle adjustment device 10 includes: a determination module 100, a data acquisition module 200, and an adjustment module 300.

[0075] Specifically, the determination module 100 is used to determine that the driver's line of sight meets the preset stability conditions when it is detected that the driver has fastened the seat belt and has been looking at the exterior rearview mirror for more than a preset time, and to control the vehicle to enter the automatic adjustment mode of the exterior rearview mirror angle.

[0076] The acquisition module 200 is used to acquire eye angle coordinates that meet preset stability conditions according to the automatic adjustment mode of the external rearview mirror angle.

[0077] The adjustment module 300 is used to convert the eye angle coordinates into the corresponding exterior rearview mirror angle data, compare the corresponding exterior rearview mirror angle data with the current exterior rearview mirror angle data to determine the adjustment angle of the exterior rearview mirror, and when the exterior rearview mirror meets the preset adjustment conditions, control the exterior rearview mirror to rotate according to the adjustment angle so that the field of view of the exterior rearview mirror is adjusted to the position corresponding to the driver's eye position.

[0078] Optionally, in one embodiment of this application, the adjustment device 10 for the exterior rearview mirror angle further includes a control module.

[0079] The control module is used to stop the vehicle from entering the automatic adjustment mode of the exterior rearview mirrors before the vehicle enters the automatic adjustment mode of the exterior rearview mirrors, provided that the driver is not wearing a seat belt or has not been looking at the exterior rearview mirrors for a preset time.

[0080] Optionally, in one embodiment of this application, the rearview mirror angle adjustment device 10 further includes: a receiving module, a reminder module, a first access permission module, and a second access permission module.

[0081] The receiving module is used to receive the pop-up command from the exterior rearview mirror before controlling the vehicle to enter the automatic adjustment mode of the exterior rearview mirror angle.

[0082] The reminder module is used to remind the driver whether to select memory mode based on the pop-up instructions.

[0083] The first access permission module is used to allow the vehicle to enter the automatic adjustment mode of the exterior rearview mirror angle when the driver is driving, if the driver selects the memory mode.

[0084] The second entry permission module is used to allow the vehicle to enter the automatic adjustment mode of the exterior rearview mirror angle when the vehicle's ignition cycle takes effect, if the driver has not selected the memory mode.

[0085] Optionally, in one embodiment of this application, the acquisition module 200 includes: an acquisition unit, an extraction unit, and a determination unit.

[0086] The acquisition unit is used to acquire images of the driver's behavior.

[0087] The extraction unit is used to extract the driver's behavior data from the behavior image and obtain the driver's eye angle based on the behavior data.

[0088] The determining unit is used to determine the eye angle coordinates that meet the preset stability conditions based on the eye angle.

[0089] Optionally, in one embodiment of this application, the adjustment module 300 includes: a coordinate acquisition unit, a position acquisition unit, and a matching unit.

[0090] The coordinate acquisition unit is used to obtain the calibrated standard angle coordinates of the exterior rearview mirror based on the corresponding exterior rearview mirror angle data.

[0091] The position acquisition unit is used to obtain the driver's eye position based on the current exterior rearview mirror angle data.

[0092] The matching unit is used to match the calibrated standard angle coordinates of the exterior rearview mirror with the driver's line of sight to determine the adjustment angle of the exterior rearview mirror.

[0093] It should be noted that the explanation of the aforementioned method for adjusting the angle of the exterior rearview mirror also applies to the device for adjusting the angle of the exterior rearview mirror in this embodiment, and will not be repeated here.

[0094] The rearview mirror angle adjustment device proposed in this application can convert eye angle coordinates into corresponding rearview mirror angle data and compare them with the current rearview mirror angle data. It converts stable eye line coordinates into the corresponding rearview mirror angle position, automatically adjusting the rearview mirror angle. This not only adapts to the driver's driving needs in different environments but also provides a faster, more efficient, and more comfortable driving experience. Therefore, it solves the problems in related technologies where, while the vehicle is in motion, the driver easily finds that the rearview mirror's field of vision is poor, affecting the driver's visibility; adjusting the mirror during driving is dangerous; and the rearview mirror angle needs to be adjusted after a change of driver, reducing user experience and resulting in low intelligence and practicality.
