Description

Technical Field

[0001] This invention relates to the field of vehicle rearview mirror control technology, and in particular to a method for adjusting a vehicle rearview mirror and a vehicle. Background Technology

[0002] In related technologies, vehicle rearview mirrors primarily rely on manual adjustment by the driver. To address the drawbacks of manual adjustment, some vehicles are equipped with a rearview mirror memory function. This function allows drivers to pre-store one or more sets of rearview mirror lens data. When the driver uses the vehicle again, they can quickly restore the previously set position with a single button press. However, the rearview mirror memory function has significant limitations. On one hand, the stored position data is fixed and cannot be dynamically adjusted based on the driver's actual physical condition and driving posture. On the other hand, setting and recalling the memory function is relatively complex, requiring the driver to perform a series of operations in the vehicle's settings menu, which is inconvenient for drivers unfamiliar with vehicle functions. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a method for adjusting a vehicle rearview mirror.

[0004] The present invention also proposes a vehicle having a control module for performing the above-described adjustment method.

[0005] A method for adjusting a vehicle rearview mirror, the method comprising: after the vehicle is started, scanning the driver using an in-vehicle scanning device to obtain the driver's eye point information and reading the seat parameter information; calculating the required angle information of the rearview mirror lens based on the eye point information and the seat parameter information; and adjusting the position of the rearview mirror lens based on the angle information.

[0006] The adjustment method according to the present invention can achieve personalized adjustment for each driver. After the vehicle is started, the scanning device acquires the driver's eye point information and reads the seat parameter information simultaneously. Since the eye point position and seat parameters are directly related to the driver's viewing angle in the rearview mirror, drivers of different heights, body types, and driving postures have different eye point positions and seat parameters. By comprehensively analyzing the driver's eye point information and seat parameter information and using a preset algorithm model, the required angle of the rearview mirror lens can be calculated, ensuring that the rearview mirror is always in the optimal position, effectively eliminating blind spots, ensuring that the driver can clearly and completely observe the situation behind the vehicle, and improving driving safety.

[0007] The adjustment method according to the present invention can automatically adjust the rearview mirror lens during driving, improving ease of use. After the vehicle is started, the scanning device automatically acquires information, eliminating the need for manual input by the driver and saving tedious operating steps. After calculating the angle information, the system automatically controls the rearview mirror lens to rotate or move to the appropriate position. The entire adjustment process requires no time or effort, making the driving process smoother and more comfortable.

[0008] The adjustment method according to the present invention can adapt to a variety of different driving scenarios. By acquiring seat parameters and combining them with eye point information to calculate the rearview mirror angle, the rearview mirror position is adjusted in a timely manner, enabling the driver to have a clear and suitable rear view, reducing operational errors caused by changes in field of vision, thereby enhancing driving stability and safety.

[0009] According to some embodiments of the present invention, after calculating the required angle information of the rearview mirror lens based on the eye point information and the parameter information of the seat, the adjustment method further includes: scanning the driver through a scanning device in the vehicle to obtain the driver's facial information, transmitting the facial information to a background system, matching the driver's driving information based on the facial information, and adjusting the angle information based on the driving information.

[0010] According to some embodiments of the present invention, the driving information includes the correction parameters set by the driver and historical rearview mirror lens angle information.

[0013] According to some embodiments of the present invention, the adjustment method further includes: acquiring the vehicle's driving speed, and determining whether the rearview mirror lens needs to be adjusted based on the vehicle's driving speed.

[0014] According to some embodiments of the present invention, determining whether the rearview mirror lens needs to be adjusted based on the vehicle's driving speed includes: determining that the vehicle's driving speed is lower than a preset speed, adjusting the position of the rearview mirror lens according to the angle information; determining that the vehicle's driving speed reaches the preset speed, and stopping the adjustment of the rearview mirror lens position.

[0015] According to some embodiments of the present invention, the vehicle is provided with a driver for adjusting the position of the rearview mirror lens, the driver being connected to a sliding rheostat; the adjustment method further includes: when the driver adjusts the position of the rearview mirror lens according to the angle information, acquiring voltage information across the sliding rheostat and the vehicle output voltage value, and determining whether to stop adjusting the position of the rearview mirror lens based on the voltage information and the vehicle output voltage value.

[0016] According to some embodiments of the present invention, determining whether to stop adjusting the position of the rearview mirror lens based on the voltage information and the vehicle output voltage value includes: stopping the adjustment of the rearview mirror lens when the difference between the voltage information and the vehicle output voltage value is within a preset range; and continuing to adjust the position of the rearview mirror lens according to the angle information when the difference between the voltage information and the vehicle output voltage value exceeds the preset range, until the difference between the voltage across the sliding rheostat and the vehicle output voltage value is within the preset range.

[0017] The vehicle according to the present invention is briefly described below.

[0018] The vehicle according to the present invention includes a control module for performing the adjustment method described in any of the above embodiments. Since the vehicle according to the present invention includes a control module for performing the adjustment method described in any of the above embodiments, the vehicle according to the present invention can automatically adjust the position of the rearview mirror lenses according to the driver's personalized information, eliminating blind spots, improving driving convenience, adapting to multiple scenarios, and enhancing driving stability and safety.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] In related technologies, vehicle rearview mirrors primarily rely on manual adjustment by the driver. To address the drawbacks of manual adjustment, some vehicles are equipped with a rearview mirror memory function. This function allows drivers to pre-store one or more sets of rearview mirror lens data. When the driver uses the vehicle again, they can quickly restore the previously set position with a single button press. However, the rearview mirror memory function has significant limitations. On one hand, the stored position data is fixed and cannot be dynamically adjusted based on the driver's actual physical condition and driving posture. On the other hand, setting and recalling the memory function is relatively complex, requiring the driver to perform a series of operations in the vehicle's settings menu, which is inconvenient for drivers unfamiliar with vehicle functions.

[0024] The following is for reference. Figure 1 A method for adjusting according to an embodiment of the present invention is described.

[0025] like Figure 1 As shown, a method for adjusting a vehicle rearview mirror includes: after the vehicle is started, scanning the driver through an in-vehicle scanning device to obtain the driver's eye point information and reading the seat parameter information; calculating the required angle information of the rearview mirror lens based on the eye point information and the seat parameter information; and adjusting the position of the rearview mirror lens based on the angle information.

[0026] When the vehicle starts, the in-vehicle scanning device is activated, allowing it to acquire driver information at the start of each drive, preparing for subsequent rearview mirror adjustments. The scanning device scans the driver, locating their eye position, or eye-point information. This eye-point information directly determines the driver's viewing angle in the rearview mirrors. Different eye-point positions require different rearview mirror angles to ensure the driver sees a complete and clear view of the rear.

[0027] Simultaneously, the seat parameter information is read. These parameters are closely related to the driver's eye position. For example, changing the seat position alters the relative position between the driver and the rearview mirror, thus changing the eye position accordingly; adjusting the seat height also affects the driver's viewing angle in the rearview mirror. Therefore, accurately obtaining seat parameters is crucial for calculating the optimal rearview mirror angle.

[0028] The system comprehensively analyzes the driver's eye position information and seat parameter information. Using pre-set algorithms and models, and considering the complex relationship between eye position and seat parameters, it calculates the required angle information for the rearview mirror lens. After calculating the appropriate angle information, it controls the rearview mirror lens to rotate or move to achieve the calculated angle position.

[0029] The adjustment method according to the present invention can achieve personalized adjustment for each driver. After the vehicle is started, the scanning device acquires the driver's eye point information and reads the seat parameter information simultaneously. Since the eye point position and seat parameters are directly related to the driver's viewing angle in the rearview mirror, drivers of different heights, body types, and driving postures have different eye point positions and seat parameters. By comprehensively analyzing the driver's eye point information and seat parameter information and using a preset algorithm model, the required angle of the rearview mirror lens can be calculated, ensuring that the rearview mirror is always in the optimal position, effectively eliminating blind spots, ensuring that the driver can clearly and completely observe the situation behind the vehicle, and improving driving safety.

[0030] The adjustment method according to the present invention can automatically adjust the rearview mirror lens during driving, improving ease of use. After the vehicle is started, the scanning device automatically acquires information, eliminating the need for manual input by the driver and saving tedious operating steps. After calculating the angle information, the system automatically controls the rearview mirror lens to rotate or move to the appropriate position. The entire adjustment process requires no time or effort, making the driving process smoother and more comfortable.

[0031] The adjustment method according to the present invention can adapt to a variety of different driving scenarios. By acquiring seat parameters and combining them with eye point information to calculate the rearview mirror angle, the rearview mirror position is adjusted in a timely manner, enabling the driver to have a clear and suitable rear view, reducing operational errors caused by changes in field of vision, thereby enhancing driving stability and safety.

[0032] Therefore, according to the adjustment method of the present invention, the rearview mirror lens can be automatically adjusted according to the driver's personalized information, eliminating blind spots, improving driving convenience, and adapting to various driving scenarios to enhance driving stability and safety.

[0033] It should be noted that the rearview mirrors include a left rearview mirror and a right rearview mirror. In the adjustment method of the present invention, at least one of the left and right rearview mirrors is adjusted independently according to the above process.

[0034] According to some embodiments of the present invention, such as Figure 1 As shown, after calculating the required angle information of the rearview mirror lens based on the eye point information and seat parameter information, the adjustment method also includes: scanning the driver through the in-vehicle scanning device to obtain the driver's facial information, transmitting the facial information to the background system, matching the driver's driving information based on the facial information, and adjusting the angle information based on the driving information.

[0035] After calculating the rearview mirror angle based on eye-point information and seat parameters, the driver's face is scanned using an in-vehicle scanning device to obtain facial information. Facial information is unique; different drivers have different facial features. Obtaining facial information can provide a basis for subsequent matching of driver-related data. Therefore, the in-vehicle scanning device achieves both eye-point information acquisition and facial information acquisition.

[0036] The in-vehicle scanning device transmits the collected facial information to the backend system. This backend system has data storage and processing capabilities, capable of storing information on multiple drivers and analyzing and matching the received data. The backend system has a built-in database that stores the facial information of each driver and their corresponding driving information. Using image recognition algorithms and data analysis technology, the backend system compares the received facial information with the information in the database, finds the matching driver record, and then extracts that driver's driving information.

[0037] Different drivers have different requirements for the field of vision of their rearview mirrors while driving. By matching driving information, the rearview mirror angle can be adjusted more precisely to better meet the driver's actual needs. The back-end system analyzes and adjusts the previously calculated rearview mirror lens angle information based on the matched driving information using preset algorithms and models, so that the rearview mirror lens angle can better adapt to the driver's personalized driving needs and provide a better rear view.

[0038] It should be noted that the scanning device can use an infrared camera, which has significant advantages in precise positioning and rapid scanning, enabling efficient acquisition of driver-related information. The infrared camera can be installed in the rearview mirror inside the vehicle, without taking up too much extra interior space, and its well-placed location allows for a comprehensive and clear scan of the driver, obtaining accurate eye-point and facial information.

[0039] According to some embodiments of the present invention, the driving information includes correction parameters set by the driver and historical rearview mirror lens angle information. The correction parameters set by the driver are parameters actively set by the driver for the rearview mirror angle adjustment system based on their actual needs and preferences. Different drivers have specific needs or preferences; for example, some drivers may be dissatisfied with the default adjustment angle of the rearview mirror due to factors such as seating posture and wish to make personalized adjustments by setting correction parameters. The correction parameters set by the driver can fully consider specific needs or preferences, making rearview mirror adjustment more flexible and diverse. Furthermore, if the driver finds that the rearview mirror angle does not meet their needs during actual driving, they can adjust the correction parameters at any time. The system will optimize the rearview mirror angle promptly based on real-time feedback to ensure the driver has the best rear visibility.

[0040] By adjusting and correcting parameters, drivers can actively participate in the rearview mirror adjustment process, modifying the angle according to their own preferences, thus improving their sense of control over the vehicle. Through the driver's active settings and real-time feedback, the system can continuously optimize the adjustment algorithm, making the rearview mirror angle more accurately meet the driver's needs, further improving driving safety and comfort.

[0041] Historical rearview mirror lens angle information records the various angles the rearview mirror lenses were at during past driving activities. Each time the rearview mirror lens position is adjusted based on the calculated angle information, the backend system synchronously records the corresponding angle information, and also stores related eye point information, seat parameters, and correction parameters. This helps to comprehensively understand the changes in rearview mirror angles under different conditions and the driver's usage habits.

[0042] By analyzing historical rearview mirror lens angle information, the backend system can understand the driver's rearview mirror usage habits. Utilizing big data, artificial intelligence, and deep learning models, it automatically optimizes the rearview mirror angle adjustment strategy. Based on the driver's past active adjustments, it proactively amplifies or reduces the adjustment range of the rearview mirror lens, allowing the backend system to more closely match the driver's actual needs when making new angle adjustments, achieving personalized default settings.

[0043] According to some embodiments of the present invention, the eye point information includes three-dimensional coordinate position data of the driver's eyes and gaze direction data of the eyes.

[0044] The three-dimensional coordinate position data of the driver's eyes refers to the precise position coordinates of the driver's left and right eyes in the three-dimensional spatial coordinate system inside the vehicle. The three-dimensional coordinate position of the eyes is fundamental to determining the driver's basic observation position inside the vehicle. By obtaining accurate three-dimensional coordinate position data, the driver's visual center position can be determined, thus providing a reference for subsequent angle adjustments.

[0045] Binocular gaze direction data refers to the direction vector that the driver's eyes are focused on during normal driving. By analyzing gaze direction, potential blind spots can be identified, and the rearview mirror angle can be adjusted accordingly to expand the field of vision.

[0046] According to some embodiments of the present invention, the parameter information of the seat includes the seat's fore-aft position, height, and tilt angle.

[0047] Changes in the seat's fore-and-aft position directly alter the relative distance between the driver and the rearview mirror. When the seat moves forward, the distance between the driver and the rearview mirror decreases, resulting in a narrower field of vision, but allowing for a clearer view of nearby objects. Conversely, when the seat moves backward, the distance to the rearview mirror increases, expanding the field of vision, but reducing the ability to observe details of nearby objects.

[0048] Adjusting the seat height changes the driver's line of sight, thus affecting their ability to observe the rear and sides of the vehicle. A higher seat position provides the driver with a wider field of vision, allowing them to spot distant and high-altitude objects earlier, but makes it more difficult to observe the area below the vehicle and the ground nearby. Conversely, a lower seat position offers a clearer view of the area below and the ground nearby, but with a relatively narrower field of vision.

[0049] The seat tilt angle primarily affects the driver's posture and back support, which in turn indirectly affects visibility. A suitable tilt angle allows the driver to maintain a comfortable posture, reducing driving fatigue, and also helps maintain a stable line of sight. If the tilt angle is too large, the driver's body will lean back, which may cause the line of sight to shift upward, affecting the observation of road conditions in front of and below the vehicle; if the tilt angle is too small, the driver's body will lean forward too much, and the line of sight may shift downward too much, making it difficult to observe distant situations.

[0050] By acquiring parameters such as the seat's fore-and-aft position, height, and tilt angle, the vehicle can automatically adjust the position of the rearview mirror lenses according to the different drivers' physical characteristics and driving habits, providing a personalized driving environment for each driver and making driving more comfortable and convenient.

[0051] According to some embodiments of the present invention, the adjustment method further includes: acquiring the vehicle's driving speed and determining whether the rearview mirror lens needs adjustment based on the vehicle's driving speed. At different vehicle speeds, the driver's focus and range of attention regarding the rear view vary. By acquiring the real-time driving speed and using it as a basis for judgment, it is possible to dynamically determine whether the rearview mirror lens needs adjustment, thereby providing the driver with a more suitable rear view and improving driving safety and comfort.

[0052] According to some embodiments of the present invention, determining whether the rearview mirror lens needs to be adjusted based on the vehicle's driving speed includes: determining that the vehicle's driving speed is lower than a preset speed, adjusting the position of the rearview mirror lens according to angle information; and determining that the vehicle's driving speed has reached the preset speed, stopping the adjustment of the rearview mirror lens position.

[0053] A preset speed is set as the dividing point, categorizing the vehicle's driving state into low-speed and high-speed scenarios. When the vehicle speed is below the preset speed, the driver requires a higher level of close-range rear visibility, and the vehicle's driving state changes frequently, necessitating constant adjustments to the rearview mirrors to obtain the best view. Conversely, when the vehicle speed reaches the preset speed, the current rearview mirror position is considered sufficient for driving needs, eliminating the need for further adjustments and avoiding unnecessary interference with driving.

[0054] According to some embodiments of the present invention, the vehicle is provided with a driver for adjusting the position of the rearview mirror lens, the driver being connected to a sliding rheostat; the adjustment method further includes: when the driver adjusts the position of the rearview mirror lens according to angle information, acquiring voltage information across the sliding rheostat and the vehicle output voltage value, and determining whether to stop adjusting the position of the rearview mirror lens based on the voltage information and the vehicle output voltage value.

[0055] The actuator is used to adjust the position of the rearview mirror lens. It receives control signals and converts electrical energy into mechanical energy to drive the rearview mirror lens to rotate or move, thereby adjusting the angle. A sliding rheostat is connected to the actuator, and its resistance changes with the adjustment of the rearview mirror lens. When the actuator drives the rearview mirror lens to adjust its position, it moves the slider on the sliding rheostat. Therefore, the position of the slider on the rheostat directly corresponds to the angle of the rearview mirror lens. The resistance of the rheostat depends on the position of the slider. As the slider moves, the resistance changes linearly, and this change in resistance directly causes a change in the voltage across the rheostat. Therefore, the voltage across the rheostat reflects the current actual position of the rearview mirror lens.

[0056] When the driver adjusts the position of the rearview mirror lens, it moves the slider of the sliding rheostat, thereby changing the resistance value of the rheostat connected in the circuit. According to Ohm's law, with a constant circuit current, a change in resistance will cause a change in the voltage across the rheostat. The vehicle's output voltage is a stable voltage reference provided by the vehicle's power system. By obtaining the voltage information across the rheostat and the vehicle's output voltage value, and comparing and analyzing them, it can be determined whether the rearview mirror lens has been adjusted to the appropriate position, and thus decide whether to stop adjusting.

[0057] By monitoring the voltage change across a sliding rheostat, the adjustment position of the rearview mirror lens can be detected. Voltage detection is simple, low-cost, and easy to implement, which can simplify the control logic and reduce the complexity and cost of the system.

[0058] According to some embodiments of the present invention, determining whether to stop adjusting the position of the rearview mirror lens based on voltage information and the vehicle output voltage value includes: stopping the adjustment of the rearview mirror lens position when the difference between the voltage information and the vehicle output voltage value is within a preset range; and continuing to adjust the position of the rearview mirror lens position according to the angle information when the difference between the voltage information and the vehicle output voltage value exceeds the preset range, until the difference between the voltage across the sliding rheostat and the vehicle output voltage value is within the preset range.

[0059] When the difference between the voltage across the sliding rheostat and the vehicle output voltage is within the preset range, it indicates that the rearview mirror lens has been adjusted to a suitable position. It can be assumed that the angle of the rearview mirror lens meets the driver's field of vision requirements, and the adjustment of the rearview mirror lens position will stop at this time.

[0060] If the difference between the determined voltage information and the vehicle's output voltage exceeds the preset range, it indicates that the rearview mirror lens has not been adjusted to the appropriate position. At this point, the position of the rearview mirror lens continues to be adjusted based on the angle information. During this adjustment process, the voltage across the sliding rheostat is monitored in real time until the difference between the voltage across the rheostat and the vehicle's output voltage falls within the preset range. Adjustment stops only after this process is complete. Through continuous adjustment, the rearview mirror lens eventually reaches the required position.
