Description

Technical Field

[0001] This invention relates to the field of rearview mirror control technology, and particularly to a rearview mirror control method. Furthermore, this invention also relates to a control device capable of implementing the rearview mirror control method, and a vehicle and computer-readable storage medium. Background Technology

[0002] Rearview mirrors are tools used by drivers to directly obtain external information about the rear, sides, and bottom of the vehicle while seated in the driver's seat; they are often referred to as the vehicle's "second eye." The presence of rearview mirrors greatly expands the driver's field of vision, helping them to understand their surroundings in a timely manner, make correct driving decisions, and thus ensure driving safety.

[0003] However, vehicles may encounter many different conditions while driving. For example, when driving at night, there may be vehicles approaching from behind. The headlights of these vehicles can have a significant impact on the driver's visual perception at night, especially when the vehicles behind have their high beams on, which may affect driving safety.

[0004] To address the impact of glare from following vehicles on drivers, one solution in existing vehicles is to equip rearview mirrors with automatically adjustable anti-glare mirrors. By adjusting the reflectivity of the rearview mirror, the amount of light entering the driver's field of vision is reduced, thus improving driving safety.

[0005] An existing method for controlling an anti-glare rearview mirror uses a time-controlled approach to achieve its anti-glare function. Structurally, the HUT (Head Unit, also known as the vehicle host) is electrically connected to the electrochromic layer inside the rearview mirror.

[0006] Because ambient light at sunrise and sunset significantly affects the driver's visibility, the controller automatically activates the auto-dimming function of the rearview mirror based on the preset sunset time, while the HUT (Head Unit, also known as the vehicle host) automatically deactivates the auto-dimming function based on the sunrise time. In this rearview mirror control method, the reflectivity of the lens remains constant, and it cannot distinguish whether there is glare from behind. If there is no glare from behind, the rearview mirror entering the auto-dimming control mode will affect the driver's visibility. However, if there is glaring light behind the vehicle, the anti-dimming effect of the rearview mirror is insufficient, making it difficult to meet the driver's needs.

[0007] Another existing method for controlling anti-glare rearview mirrors integrates an ambient light sensor and a glare sensor into the mirror itself, with the ambient light sensor and glare sensor respectively located on the front and rear sides of the mirror. Structurally, the ambient light sensor and glare sensor are connected to a PCB board, which in turn is electrically connected to the electrochromic layer within the rearview mirror.

[0008] The ambient light sensor and glare sensor are used to collect light intensity data on the front and rear sides of the rearview mirror, respectively. Based on the difference in light intensity on the front and rear sides of the rearview mirror, the PCB board then adjusts the reflectivity of the lens in real time according to the predetermined reflectivity value.

[0009] While this rearview mirror control method is more effective than the previous one, it still presents challenges. Different drivers have varying sensitivities to light, and the accuracy of ambient light collection can be affected by factors such as the color of the vehicle's tint and the brightness of the screen inside the cabin. Using the same control method for different vehicle models could lead to problems, such as excessive glare that obstructs the driver's view, or insufficient glare that still poses a risk to safe driving and fails to meet individual driver needs. Summary of the Invention

[0010] In view of this, the present invention aims to propose a rearview mirror control method that is applicable to vehicles with different film colors and different cabin screen brightness, and meets the personalized needs of different drivers.

[0011] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0012] A rearview mirror control method, the method comprising:

[0013] When preset conditions are met, the rearview mirror will enter the anti-glare automatic control mode.

[0014] In the anti-glare automatic control mode, the reflectivity of the rearview mirror is controlled in real time to reach the preset reflectivity;

[0015] In the anti-glare automatic control mode, manual input of operation commands is allowed. When a first operation command is received, the reflectivity of the rearview mirror is controlled to increase by a first preset reflectivity value in real time based on the preset reflectivity. When a second operation command is received, the reflectivity of the rearview mirror is controlled to decrease by a second preset reflectivity value in real time based on the preset reflectivity.

[0016] Furthermore, the real-time control of the reflectivity of the rearview mirror to reach a preset reflectivity is achieved by real-time control of the driving voltage of the rearview mirror to a preset driving voltage;

[0017] The control of the reflectivity of the rearview mirror to increase by a first preset reflectivity value in real time based on a preset reflectivity is achieved by decreasing the first preset driving voltage in real time on the preset driving voltage of the rearview mirror, wherein the ratio of the first preset driving voltage to the preset driving voltage is a constant value.

[0018] The control of the reflectivity of the rearview mirror to decrease by a second preset reflectivity value in real time based on the preset reflectivity is achieved by increasing the second preset driving voltage in real time on the preset driving voltage of the rearview mirror, wherein the ratio of the second preset driving voltage to the preset driving voltage is a constant value.

[0019] Furthermore, satisfying the preset conditions includes the ambient light intensity being less than a first preset ambient light intensity threshold.

[0020] When the ambient light intensity is greater than or equal to the first preset ambient light intensity threshold, the rearview mirror is not allowed to enter the anti-glare automatic control mode.

[0021] Furthermore, in the anti-glare automatic control mode, when the ambient light intensity is less than the second preset ambient light intensity threshold and the glare intensity is within different ranges of the first preset glare intensity threshold, the reflectivity of the rearview mirror is controlled to change according to the state curve corresponding to the range of the first preset glare intensity threshold.

[0022] Furthermore, in the anti-glare automatic control mode, when the ambient light intensity is less than the first preset ambient light intensity threshold and greater than or equal to the second preset ambient light intensity threshold, and the glare intensity is within different ranges of the second preset glare intensity threshold, the reflectivity of the rearview mirror is controlled to change according to the state curve corresponding to the range of the second preset glare intensity threshold.

[0023] Furthermore, in the anti-glare automatic control mode, when a reading light illumination signal is received, the rearview mirror is controlled to exit the anti-glare automatic control mode.

[0024] Furthermore, in the anti-glare automatic control mode, when a reverse gear signal is received from the vehicle, the rearview mirror is controlled to exit the anti-glare automatic control mode.

[0025] The rearview mirror control method of this invention, after controlling the rearview mirror to enter anti-glare mode, can also receive a first operation command and a second operation command input manually. Upon receiving the first operation command, the reflectivity of the rearview mirror increases; upon receiving the second operation command, the reflectivity decreases. This makes the rearview mirror control method more user-friendly. With the addition of manual control to modify the reflectivity of the rearview mirror, even if different drivers have different sensitivities to light or different viewing angles, this rearview mirror control method can better meet the needs of different drivers. It allows drivers to adjust the reflectivity of the rearview mirror to a suitable range according to their own circumstances, enabling them to obtain a clearer field of vision. Furthermore, the anti-glare level of the rearview mirror does not affect the driver's safe driving. This rearview mirror control method is used to control the rearview mirrors of a vehicle, thereby improving vehicle driving safety.

[0026] Furthermore, when the ambient light intensity is within different preset ambient light intensity threshold ranges, a control method corresponding to each preset ambient light intensity threshold range is executed, so that the control method of the rearview mirror can execute the corresponding control method according to the ambient light intensity, which helps to improve driving safety.

[0027] When the ambient light intensity is greater than or equal to the first preset ambient light intensity threshold, the rearview mirror is not allowed to enter the anti-glare automatic control mode, which helps to ensure the driver's rear visibility and thus improves the safety of vehicle driving.

[0028] When the ambient light intensity is less than the second preset ambient light intensity threshold, and the glare intensity falls within different ranges of the first preset glare intensity threshold, the reflectivity of the rearview mirror is controlled according to the state curve corresponding to the range of the first preset glare intensity threshold. This is equivalent to executing a corresponding control strategy based on the glare intensity level, which can make the rearview mirror achieve a more suitable reflectivity, thus balancing the driver's field of vision and anti-glare requirements, and further improving vehicle driving safety.

[0029] When the ambient light intensity is less than the first preset ambient light intensity threshold but greater than or equal to the second preset ambient light intensity threshold, and the glare intensity falls within different ranges of the second preset glare intensity threshold, the reflectivity of the rearview mirror is controlled according to the state curve corresponding to the range of the second preset glare intensity threshold. Similarly, based on the glare intensity level, the corresponding control strategy is executed, which can make the rearview mirror achieve a more suitable reflectivity, which is beneficial to both the driver's field of vision and the need for anti-glare, and can also further improve the safety of vehicle driving.

[0030] Furthermore, upon receiving a reading light illumination signal, the rearview mirror exits the automatic anti-glare control mode, ensuring the driver has a true rear view and improving vehicle safety. Similarly, upon receiving a reverse gear signal, the rearview mirror exits the automatic anti-glare control mode, again ensuring the driver's rear view and improving vehicle safety. This rearview mirror control method, which allows the mirror to exit automatic anti-glare control mode based on either the reading light illumination signal or the reverse gear signal, provides superior safety assurance.

[0031] Furthermore, this invention also proposes a rearview mirror control device, including an input unit and a controller; wherein,

[0032] The input unit is used to send a first operation instruction and a second operation instruction to the controller;

[0033] The controller is used to control the rearview mirror to enter the anti-glare automatic control mode when preset conditions are met.

[0034] In the anti-glare automatic control mode, the reflectivity of the rearview mirror is controlled in real time to reach the preset reflectivity;

[0035] In the anti-glare automatic control mode, manual input of operation commands is allowed. When a first operation command is received, the reflectivity of the rearview mirror is controlled to increase by a first preset reflectivity value in real time based on the preset reflectivity. When a second operation command is received, the reflectivity of the rearview mirror is controlled to decrease by a second preset reflectivity value in real time based on the preset reflectivity.

[0036] Another object of the present invention is to provide a vehicle equipped with a controller capable of performing the rearview mirror control method as described above.

[0037] Another object of the present invention is a computer-readable storage medium for storing a computer program that, when executed by a processor, enables the implementation of the rearview mirror control method as described above.

[0038] The rearview mirror control device, vehicle, and computer-readable storage medium described in this invention have the same beneficial effects as the aforementioned rearview mirror control method compared to the prior art, and will not be repeated here. Attached Figure Description

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

[0048] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] Example 1

[0050] This embodiment relates to a rearview mirror control method, which is particularly suitable for controlling existing rearview mirrors with anti-glare function. It can adjust the reflectivity of the rearview mirror according to the driver's will and preferences, thereby adjusting the anti-glare degree of the rearview mirror, realizing the driver's customized needs, and taking into account the driver's rear visibility and vehicle driving safety, thus having good practicality.

[0051] To better understand the rearview mirror control method of this embodiment, the structure of the rearview mirror with anti-glare function will be briefly described first. The anti-glare rearview mirror mainly includes an electrochromic mirror, a sensor for detecting ambient light, a sensor for detecting glare, and a controller. These parts work together to achieve the anti-glare effect by sensing the light intensity and adjusting the color of the electrochromic mirror surface, thereby improving driving safety.

[0052] During operation, the electronic controller of the anti-glare rearview mirror outputs a voltage to the electrochromic layer of the mirror. The voltage on the electrochromic layer changes the color of the electrochromic layer (the electrochromic layer of the mirror and the conductive layer). The higher the voltage, the darker the color of the electrochromic layer. This color change of the electrochromic layer makes the reflectivity of the rearview mirror lower, thereby reducing the intensity of the light reflected by the rearview mirror. When strong light is reflected into the driver's eyes, it becomes dark light, thus achieving the effect of preventing glare.

[0053] Rearview mirrors are mainly classified into the following types according to their installation position, specifically including an interior rearview mirror 7 and two exterior rearview mirrors 8. The rearview mirror control method of this embodiment can be used to control any one or any two of the interior rearview mirrors 7 and exterior rearview mirrors 8, or to control all three rearview mirrors simultaneously.

[0054] The interior rearview mirror 7 is installed on the front side of the windshield in the driver's cabin. It is mainly to help the driver to check the situation behind the vehicle. The interior rearview mirror 7 can observe the situation behind without significantly changing the driver's line of sight, which can improve the convenience and safety of driving.

[0055] The exterior rearview mirror 8 is generally installed on the vehicle door, and some models also have it mounted on the fender. The exterior rearview mirror 8 mainly reflects the traffic conditions to the side and rear of the vehicle, and is an important reference for the driver when changing lanes, overtaking, turning and other operations.

[0056] The existing interior rearview mirror 7 and exterior rearview mirror 8, as key safety components for vehicle operation, suffer from severe glare from surrounding lights during nighttime driving, significantly impacting driving safety. Current solutions involve adding electrochromic auto-anti-glare lenses, or electrochromic lenses, to the rearview mirrors. A controller adjusts the brightness of these lenses to reduce the impact of nighttime lights on the driver. However, the existing lens color-changing strategies and anti-glare levels mentioned in the background art fail to meet the needs of diverse customers. Based on the above design concept and overall rearview mirror structure description, and to better meet the usage needs of different customers, this embodiment provides an exemplary structure for the rearview mirror control method as follows: Figure 1 As shown, it mainly includes the following steps.

[0057] S101. When the preset conditions are met, control the rearview mirror to enter the anti-glare automatic control mode.

[0058] It should be noted that the anti-glare automatic control mode refers to a function used to reduce or eliminate the interference of strong light on the driver's vision. This step is specifically implemented by the rearview mirror controller described below. In this embodiment, the anti-glare automatic control mode mentioned is a function in the prior art. In the anti-glare automatic control mode, the controller automatically adjusts the reflectivity of the rearview mirror according to the intensity of ambient light and the intensity of glare, so as to prevent excessive glare from affecting the driver's vision.

[0059] It should be noted that in existing rearview mirror control methods, the reflectivity of the rearview mirror is always automatically adjusted. However, in actual use, the inventors found that different drivers have different eyesight and sensitivity to light. Furthermore, due to the different heights of different drivers, the angle from which drivers observe the rearview mirror when in the driving position is different. The change in angle will result in different light entering different drivers due to the reflection of the rearview mirror. Therefore, the existing method of automatically adjusting the reflectivity of the rearview mirror cannot well meet the needs of all drivers. Thus, it is necessary to add a manual adjustment mode for the reflectivity of the rearview mirror.

[0060] In actual vehicles, a command input unit, such as a button or touch screen, can be installed. When the driver or passenger operates the command input unit, the command input unit can send command information to the controller. When the controller receives the command information input by the command input unit, it controls the rearview mirror to enter the anti-glare automatic control mode. If the command input unit is operated again, the controller can control the rearview mirror to exit the anti-glare automatic control mode.

[0061] In this method, a single command input unit is used as an example for illustration, as this provides high integration and facilitates placement. It should be understood that two command input units are also possible; the controller simply needs to be able to control the rearview mirror to enter or exit the anti-glare automatic control mode when it receives the corresponding command information. For example, based on the command information sent to the controller by one command input unit, the controller controls the rearview mirror to enter the anti-glare automatic control mode. Receiving the command information sent to the controller by that command input unit indicates that the preset conditions have been met. Based on the command information sent to the controller by the other command input unit, the controller controls the rearview mirror to exit the anti-glare automatic control mode. In a preferred embodiment, the controller controls the rearview mirror to enter the anti-glare automatic control mode. In addition to the command information input by the command input unit, it can also be based on the ambient light intensity and the glare intensity sensed by the sensors. For example, the ambient light intensity can be detected by the rain and light sensor 3, and the light intensity information obtained by the rearview camera 4 can be used as the detected glare intensity. Then, the controller controls the rearview mirror to execute the corresponding control strategy to realize the function of controlling the rearview mirror to enter and exit the anti-glare automatic control mode.

[0062] In the following description, the function of the rearview mirror entering and exiting the automatic anti-glare control mode is achieved by detecting the ambient light illuminance through the rain and light sensor 3. It should be understood that, in addition to the method described above, the function of controlling the rearview mirror to enter and exit the automatic anti-glare control mode can also refer to methods in the prior art. It should be understood that when controlling the rearview mirror to enter the automatic anti-glare control mode, the controller can control the rearview mirror to perform the following step S102.

[0063] It should be noted that in the actual control method, the controller can first determine whether it has received the instruction information from the instruction input unit requesting to enter the anti-glare automatic control mode, and then determine whether the ambient light intensity is less than the first preset ambient light intensity threshold according to the following method, and enter the anti-glare automatic control mode when the ambient light intensity is less than the first preset ambient light intensity threshold.

[0064] S102. In the automatic anti-glare control mode, the reflectivity of the rearview mirror is controlled in real time to reach the preset reflectivity. It should be noted that in the automatic anti-glare control mode, the reflectivity of the rearview mirror is not fixed, but is adjusted in real time by the controller according to the ambient light intensity and the glare intensity according to the preset state curve, which will be described in detail below.

[0065] S103. In the anti-glare automatic control mode, manual input of operation commands is allowed. When the first operation command is received, the reflectivity of the rearview mirror is increased by the first preset reflectivity value in real time based on the preset reflectivity. When the second operation command is received, the reflectivity of the rearview mirror is decreased by the second preset reflectivity value in real time based on the preset reflectivity.

[0066] In one preferred embodiment, the reflectivity of the rearview mirror is controlled in real time to reach a preset reflectivity, which is achieved by controlling the driving voltage of the rearview mirror to a preset driving voltage in real time.

[0067] The reflectivity of the rearview mirror is controlled by increasing a first preset reflectivity value in real time based on a preset reflectivity. This is achieved by decreasing the first preset driving voltage on top of the preset driving voltage of the rearview mirror, where the ratio of the first preset driving voltage to the preset driving voltage is a constant value. The reflectivity of the rearview mirror is also controlled by decreasing a second preset reflectivity value based on the preset reflectivity. This is achieved by increasing the second preset driving voltage on top of the preset driving voltage of the rearview mirror, where the ratio of the second preset driving voltage to the preset driving voltage is a constant value.

[0068] It should be noted that the preset reflectivity of the rearview mirror is different when the ambient light intensity and the glare intensity are within different threshold ranges. However, according to the adjustment method of this embodiment, the ratio of the first preset driving voltage that needs to be reduced at each time to the current preset driving voltage is fixed, and the ratio of the second preset driving voltage that needs to be increased at each time to the current preset driving voltage is fixed. This helps the driver obtain a clearer field of vision, and the adjusted reflectivity of the rearview mirror can better meet the driver's needs.

[0069] It should be noted that step S103 is implemented by the controller described below. Specifically, the controller can change the driving voltage input to the rearview mirror by referring to the method described above or other existing methods. When the driving voltage increases, the color of the rearview mirror becomes darker, the reflectivity of the rearview mirror decreases, and less light is reflected from the rearview mirror to the driver's eyes.

[0070] As the driving voltage decreases, the color of the rearview mirror gradually changes from dark to bright, and its reflectivity gradually increases from low to high. Consequently, the amount of light reflected from the mirror to the driver's eyes gradually increases. When there is no driving voltage, i.e., when the rearview mirror is not in anti-glare automatic control mode, the mirror is very bright, and its reflectivity reaches its maximum.

[0071] It should be noted that both the first and second operation commands are manually triggered by the input unit described below, which then sends the first and second operation commands to the controller. Specifically, the first operation command originates from the input unit described below, which is operated by the driver or passenger. The input unit can be, for example, a button or a touch screen. Specifically, when the driver or passenger operates the input unit, the input unit sends command information to the rearview mirror's controller. Upon receiving the first operation command, the rearview mirror's controller reduces the reflectivity of the rearview mirror, which can be achieved by increasing the driving voltage of the rearview mirror's electrochromic layer.

[0072] The second operation command is similar to the first operation command, and it also comes from the input unit described below. This input unit can be an input unit that can input the first operation command, such as a touch screen. If the driver presses the input unit for a short time, the controller can receive the first operation command sent by the input unit. If the driver presses the input unit for a long time, such as for more than 3 seconds, the controller can receive the second operation command sent by the input unit.

[0073] It should be understood that the functions of the first and second operation commands are integrated into the same input unit, making the rearview mirror control device simple in structure and convenient in arrangement. However, it should also be understood that there can also be two input units, with each input unit corresponding to the first and second operation commands respectively. When the driver triggers one input unit, that input unit sends the first operation command to the rearview mirror controller, and when the driver triggers the other input unit, that input unit sends the second operation command to the rearview mirror controller.

[0074] It should also be noted that when one input unit is briefly triggered, the first preset driving voltage can be reduced; when one input unit is triggered for a long time, the third preset driving voltage value can be reduced, with the first preset driving voltage being less than the third preset driving voltage. Conversely, when another input unit is briefly triggered, the second preset driving voltage can be increased; and when another input unit is triggered for a long time, the fourth preset driving voltage can be increased, with the second preset driving voltage value being less than the fourth preset driving voltage value. Specifically, controlling the rearview mirror's reflectivity to increase by the first preset reflectivity value and controlling the rearview mirror's reflectivity to decrease by the second preset reflectivity value are both implemented based on the rearview mirror entering the anti-glare automatic control mode described below. For example, if the rearview mirror is providing driving voltage to the electrochromic layer of the rearview mirror according to its anti-glare curve, when the rearview mirror controller receives the first or second operation command, it increases or decreases the driving voltage of the electrochromic layer of the rearview mirror based on the driving voltage to decrease or increase the reflectivity of the rearview mirror.

[0075] It should be understood that when the driving voltage increases by the first preset driving voltage, the reflectivity decreases by the first preset reflectivity value, and when the driving voltage decreases by the first preset driving voltage, the reflectivity increases by the first preset reflectivity value. The first preset driving voltage and the second preset driving voltage can be stored in the memory described below.

[0076] Specifically, increasing or decreasing the driving voltage of the electrochromic layer of the rearview mirror can be done by increasing or decreasing a fixed driving voltage value, or by increasing or decreasing the driving voltage value proportionally to the current driving voltage. In other words, the driving voltage that is increased or decreased is not a constant value.

[0077] It should be noted that in the description of this embodiment, the specific values ​​of the first preset reflectivity value and the second preset reflectivity value can be the same or different, and the value of the driving voltage can be preset according to the requirements. In this embodiment, the example of increasing or decreasing the preset driving voltage value to achieve a preset change in reflectivity value is used for explanation. In addition, the reflectivity of the rearview mirror can also be increased or decreased according to other existing methods. As in this embodiment, the voltage signal output by the rearview mirror controller to the electrochromic lens is adjusted by the rearview mirror controller (such as HUT) according to the set anti-glare degree ratio of 0-100% before being output to the lens to adapt to the setting requirements of different drivers.

[0078] For example, when neither the first nor the second operation command is received, the rearview mirror controller outputs a driving voltage of 1.1V to the electrochromic lens. However, when the second operation command is received, if the preset increase rate of the driving voltage is 10%, the driving voltage output by the rearview mirror controller to the electrochromic lens becomes 1.21V. Furthermore, this adjustment of the driving voltage is based on a preset anti-glare curve, ensuring that within a certain range of ambient light intensity and glare intensity, the driving voltage at each point on the preset anti-glare curve is adjusted by an increase rate of 10%, thus better meeting the driver's needs for both visibility and anti-glare levels.

[0079] As a preferred embodiment, if the rearview mirror enters the anti-glare automatic control mode, when the ambient light intensity is within different preset ambient light intensity threshold ranges, the control method corresponding to each preset ambient light intensity threshold range is executed.

[0080] Because the intensity of ambient light has a significant impact on the reflectivity of rearview mirrors and human visual perception, for example, during the day, even if there is a vehicle behind and it is using high beams, the visual impact on the driver is relatively small. However, at night, even if the vehicle behind is using low beams, the distance between the front and rear vehicles and the left and right vehicles may change at any time during the driving process, which may lead to a greater visual impact on the driver for a certain period of time, and may also affect the vehicle's safety.

[0081] Therefore, in this embodiment, when the ambient light intensity is within different preset ambient light intensity threshold ranges, a control method corresponding to each preset ambient light intensity threshold range is executed, so that the control method of the rearview mirror can execute the corresponding control method according to the ambient light intensity, which helps to improve driving safety.

[0082] For example, a vehicle with an existing rain light sensor 3 collects ambient light signals and sends the collected ambient light signals to the controller of the rearview mirror. To better understand the control method of the rearview mirror in this embodiment, the ambient light intensity collected by the rain light sensor 3 is divided into three levels. For example, the first preset ambient light intensity threshold is 90 lux, and the second preset ambient light intensity threshold is 10 lux.

[0083] When the ambient light intensity is greater than or equal to 90 lux, the light intensity within this range represents daytime light. When the ambient light intensity is less than 10 lux, the light intensity within this range represents nighttime light. When the ambient light intensity is less than 90 lux but greater than or equal to 10 lux, the light intensity within this range represents dawn or dusk light.

[0084] In this embodiment, the control methods corresponding to the three levels of ambient light intensity will be described in detail below. It should be understood that the ambient light intensity can be divided into three levels, or other numbers, such as two, four, or five levels. It should be understood that the more precise the division of the light intensity levels, the more accurate the anti-glare effect will be. However, based on the current experimental results, dividing the ambient light intensity into three levels is sufficient to meet the driver's needs.

[0085] Furthermore, after the glare intensity signal collected by the rearview camera 4 is sent to the controller of the rearview mirror, this embodiment divides the glare light into four levels according to the light intensity range. When the glare intensity is within different ranges, the controller will output a corresponding driving voltage signal to the electrochromic lens of the rearview mirror according to the anti-glare curve corresponding to the light intensity of each of the four levels. In this embodiment, for example, a driving voltage signal of 0-1.4V can be sent to the electrochromic lens of the rearview mirror to adjust the reflectivity of the rearview mirror.

[0086] like Figure 3 The diagram shown is an exemplary schematic of an anti-glare curve. Figure 3In the diagram, the horizontal axis represents the ambient light intensity, the vertical axis represents the glare intensity, and the four anti-glare curves represent the reflectance corresponding to the ambient light and glare intensity, respectively. From bottom to top, the reflectances represented by each curve are, for example, 20%, 40%, 60%, and 80%. It should be understood that... Figure 3 The above is just one example. The ambient light and glare corresponding to each anti-glare curve can be determined according to the specific situation, and the reflectivity represented by each curve can also be determined according to the actual situation.

[0087] In the following description, this embodiment divides the glare intensity into levels greater than or equal to 0 lux and less than or equal to 1 lux, greater than 1 lux and less than or equal to 5 lux, greater than 5 lux and less than or equal to 10 lux, and greater than 10 lux. It should be understood that, in addition to being divided into four levels, the glare intensity can also be divided into other numbers, such as two, three, or five levels. It should be understood that the more precise the division of the glare intensity levels, the more accurate the anti-glare effect will be. However, based on current experimental results, dividing the glare intensity into four levels is sufficient to meet the driver's needs.

[0088] In a preferred embodiment, satisfying the preset conditions includes the ambient light intensity being less than a first preset ambient light intensity threshold. That is, the preset conditions are satisfied when the ambient light intensity is less than the first preset ambient light intensity threshold, and this condition allows entry into the anti-glare automatic control mode. Conversely, when the ambient light intensity is greater than or equal to the first preset ambient light intensity threshold, the rearview mirror is not allowed to enter the anti-glare automatic control mode.

[0089] In this embodiment, the first preset ambient light intensity threshold is 90 lux. When the ambient light intensity is greater than or equal to 90 lux, it represents daytime. At this time, vehicles behind generally do not turn on their headlights. Even if vehicles behind turn on their headlights, the visual impact of the lights from vehicles behind during the day is relatively small.

[0090] Therefore, in this embodiment, when the ambient light intensity is greater than or equal to the first preset ambient light intensity threshold, the rearview mirror is not allowed to enter the anti-glare automatic control mode, which helps to ensure the driver's rear view and thus improve the safety of vehicle driving. At the same time, it also makes it convenient for the driver to adjust the position of the rearview mirror independently, thereby meeting the needs of different customers.

[0091] As a preferred implementation, in the anti-glare automatic control mode, when the ambient light intensity is less than the second preset ambient light intensity threshold and the glare intensity is within different ranges of the first preset glare intensity threshold, the reflectivity of the rearview mirror is controlled to change according to the state curve corresponding to the range of the first preset glare intensity threshold.

[0092] In this embodiment, the second preset ambient light intensity threshold is 10 lux, and the glare intensity is divided into two levels. Specifically, the first preset glare intensity threshold range includes two levels: greater than or equal to 0 lux and less than or equal to 1 lux, and greater than 1 lux and less than or equal to 5 lux. When the glare intensity is within these two glare intensity ranges, the controller sends a driving voltage to the electrochromic lens of the corresponding rearview mirror according to the state curve pre-stored in the memory corresponding to the glare intensity range.

[0093] It should be understood that when the ambient light intensity is less than 10 lux, the corresponding glare intensity can be divided into two levels, or other levels, such as three, four, or five levels.

[0094] In this embodiment, when the ambient light intensity is less than the second preset ambient light intensity threshold and the glare intensity is within different ranges of the first preset glare intensity threshold, the reflectivity of the rearview mirror is controlled to change according to the state curve corresponding to the range of the first preset glare intensity threshold. This is equivalent to executing a corresponding control strategy based on the glare intensity level, which can make the rearview mirror achieve a more suitable reflectivity, which is beneficial to taking into account both the driver's field of vision and the need for anti-glare, and can further improve the safety of vehicle driving.

[0095] As a preferred implementation, in the anti-glare automatic control mode, when the ambient light intensity is less than a first preset ambient light intensity threshold and greater than or equal to a second preset ambient light intensity threshold, and the glare intensity is within different ranges of the second preset glare intensity threshold, the reflectivity of the rearview mirror is controlled to change according to the state curve corresponding to the range of the second preset glare intensity threshold.

[0096] In this embodiment, as described above, the first preset ambient light intensity threshold is 90 lux, the second preset ambient light intensity threshold is 10 lux, and the glare intensity is divided into two levels. Specifically, the second preset glare intensity threshold range includes two levels: greater than 5 lux and less than or equal to 10 lux, and greater than 10 lux. When the glare intensity is within these two glare intensity ranges, the controller sends a driving voltage to the electrochromic lens of the corresponding rearview mirror according to the state curve pre-stored in the memory corresponding to the glare intensity range.

[0097] It should be understood that when the ambient light intensity is less than 90 lux and greater than or equal to 10 lux, the corresponding glare intensity can be divided into two levels, or other levels, such as three, four, or five levels.

[0098] In this embodiment, when the ambient light intensity is less than a first preset ambient light intensity threshold but greater than or equal to a second preset ambient light intensity threshold, and the glare intensity falls within different ranges of the second preset glare intensity threshold, the reflectivity of the rearview mirror is controlled according to the state curve corresponding to the range of the second preset glare intensity threshold. Similarly, based on the glare intensity level, the corresponding control strategy is executed, which can make the rearview mirror achieve a more suitable reflectivity, which is beneficial to both the driver's field of vision and the need for anti-glare, and can also further improve the safety of vehicle driving.

[0099] As a preferred implementation, in the anti-glare automatic control mode, when the reading light 5 is illuminated, the rearview mirror is controlled to exit the anti-glare automatic control mode. This step is implemented by the controller, which helps to ensure the driver's rear visibility and improves the safety of vehicle driving.

[0100] It should be noted that reading light 5 is, for example, the overhead light in the driver's cabin. When reading light 5 is lit, the ambient light inside the driver's cabin brightens. If the rearview mirror is in anti-glare automatic control mode, the controller will control the rearview mirror to exit the anti-glare automatic control mode. If the rearview mirror is not in anti-glare automatic control mode but reading light 5 is already lit, the controller will not allow the rearview mirror to enter the anti-glare automatic control mode. This allows the driver to obtain a clearer rear view, thereby improving vehicle driving safety.

[0101] It should be understood that the reading light 5 in this embodiment is not limited to the overhead light in the driver's cab. All vehicle lights in the driver's cab that can improve the ambient light brightness in the driver's cab are within the scope of the reading light 5. The reading light 5 mainly refers to vehicle lights installed in the driver's cab that may affect the rearview mirror's field of vision.

[0102] It should be noted that the function of controlling the reading light 5 to turn on and off can be implemented by the vehicle's controller, or by the control switch of the reading light 5. When the function of controlling the reading light 5 to turn on and off is implemented by the vehicle's controller, the information on whether the reading light 5 is on or off is transmitted from the vehicle's sensors to the rearview mirror controller.

[0103] When the reading light 5's on / off function is controlled by a control switch, a sensor can be installed near the control switch to monitor its operating status. Specifically, the existing method can be referenced, and the sensor transmits the operating status information of the control switch to the rearview mirror's controller. Based on the operating status of the control switch, the controller can control the rearview mirror to decide whether to allow entry into the anti-glare automatic control mode, or control the rearview mirror to exit the anti-glare automatic control mode when it receives a signal that the reading light 5 is lit.

[0104] As a preferred implementation, in the anti-glare automatic control mode, when a reverse gear signal is received from the vehicle, the rearview mirror is controlled to exit the anti-glare automatic control mode. This step is implemented by the controller.

[0105] It should be noted that when the vehicle is in reverse, a clearer rear view for the driver is beneficial for ensuring driving safety. If the rearview mirror is in anti-glare automatic control mode, the controller will control the rearview mirror to exit the anti-glare automatic control mode. If the rearview mirror is not in anti-glare automatic control mode while the vehicle is reversing, the controller will not allow the rearview mirror to enter anti-glare automatic control mode, thus providing the driver with a clearer rear view and improving driving safety.

[0106] It should be noted that the vehicle's reverse gear information can be obtained from the vehicle's gear position sensor, as detailed in existing technologies. When the gear position sensor detects that the vehicle is reversing, it sends this information to the rearview mirror controller. The controller then determines whether to allow the rearview mirror to enter anti-glare automatic control mode based on whether the vehicle is reversing, or to exit anti-glare automatic control mode upon receiving a reverse gear signal. Besides obtaining reverse gear information from the gear position sensor, the rearview mirror controller can also obtain it from other controllers on the vehicle, such as the power domain controller described below.

[0107] It should be noted that when a reverse gear signal is received, controlling the rearview mirror to exit the automatic anti-glare control mode also helps ensure the driver's rear visibility and improves vehicle safety. The reflectivity of the rearview mirror can be controlled based on either the reading light 5 illumination signal or the reverse gear signal, resulting in superior safety performance.

[0108] The rearview mirror controller mentioned in this embodiment can be, for example, an existing controller on the vehicle, such as an existing CEM (Central Electronic Module), or other domain controllers, or a separate independent rearview mirror controller can be set up separately in the vehicle.

[0109] The rearview mirror control method of this embodiment can receive a first operation command and a second operation command after controlling the rearview mirror to enter the anti-glare mode. When the first operation command is received, the reflectivity of the rearview mirror is increased, and when the second operation command is received, the reflectivity of the rearview mirror is decreased, making the rearview mirror control method more user-friendly.

[0110] Even though different drivers have different sensitivities to light, this rearview mirror control method can better meet the needs of different drivers. It allows drivers to adjust the reflectivity of the rearview mirror to a suitable range according to their own situation, so that the driver can obtain a clearer field of vision. Moreover, the anti-glare degree of the rearview mirror will not affect the driver's safe driving. This rearview mirror control method is used to control the vehicle's rearview mirrors, which helps to improve the safety of vehicle driving.

[0111] Furthermore, the rearview mirror control method of this embodiment can rely on the existing hardware integration of the whole vehicle. Based on the traditional automatic anti-glare control method, this control method integrates an algorithm for automatically adjusting the reflectivity of the lens in the controller of the rearview mirror. The ambient light intensity uses the signal from the existing vehicle rain and light sensor 3, and the glare intensity at the rear is processed by the rearview camera 4. The reflectivity of the lens is automatically adjusted according to the ambient light intensity and the glare intensity. This method has a low cost and a good effect on improving the driving safety of the vehicle.

[0112] Example 2

[0113] This embodiment relates to a rearview mirror control device, which mainly includes an input unit and a controller to implement the rearview mirror control method as described in Embodiment 1. The input unit is used to send a first operation command and a second operation command to the controller. The controller is used to control the rearview mirror to enter an anti-glare automatic control mode when preset conditions are met. In the anti-glare automatic control mode, the reflectivity of the rearview mirror is controlled in real time to reach a preset reflectivity. Manual input of operation commands is allowed in the anti-glare automatic control mode. Upon receiving the first operation command, the reflectivity of the rearview mirror is increased in real time by a first preset reflectivity value based on the preset reflectivity. Upon receiving the second operation command, the reflectivity of the rearview mirror is decreased in real time by a second preset reflectivity value based on the preset reflectivity.

[0114] To better understand the rearview mirror control device of this embodiment, such as Figure 2 As shown, in this embodiment, an input unit for adjusting the anti-glare level of the lens is added to the controller (such as HUT) of the rearview mirror. The anti-glare level can be adjusted arbitrarily from 0-100%. The inner rearview mirror 7 and the outer rearview mirror 8 are set separately to meet the needs of different customers and can better cope with vehicles with different colored films, screen brightness, etc.

[0115] Figure 2 The diagram shows an exemplary structure of the rearview mirror control device in this example. The first controller 1 is connected to the rain and light sensor 3, the reading light 5, and the powertrain domain unit (PDCU) 6, respectively. The first controller 1 is connected to the second controller 2, and the second controller 2 is connected to the electrochromic lens of the interior rearview mirror 7 and the electrochromic lens of the exterior rearview mirror 8, respectively.

[0116] It should be noted that the rain and light sensor 3 is used to detect the ambient light intensity in Embodiment 1 and transmits the light intensity signal to the first controller 1. The detection method for the reading light 5's on / off state and the method for transmitting the reading light 5's on / off signal to the first controller 1 are the same as described in Embodiment 1. The power domain controller 6 is used to transmit the obtained reverse gear information to the first controller 1. The rearview mirror camera is used to transmit the acquired glare intensity signal to the first controller 1.

[0117] The first controller 1 can be, for example, an existing CEM (Central Electronic Module) on the vehicle, while the second controller 2 can be, for example, another existing domain controller on the vehicle. The first controller 1 processes all or part of the ambient light intensity information, glare intensity information, reading light 5 on / off information, and reverse gear information and transmits them to the second controller 2. The second controller 2 transmits the control information from the first controller 1 to the electrochromic lens of the interior rearview mirror 7 and the electrochromic lens of the exterior rearview mirror 8, respectively. Alternatively, the second controller 2 processes the information that the first controller 1 has not processed and transmits it to the electrochromic lens of the interior rearview mirror 7 and the electrochromic lens of the exterior rearview mirror 8, respectively, thereby achieving the purpose of adjusting the interior rearview mirror 7 and the exterior rearview mirror 8 respectively.

[0118] It should be understood that the second controller 2 can also be connected only to the electrochromic lens of the interior rearview mirror 7, or the second controller 2 can be connected only to the electrochromic lens of the exterior rearview mirror 8. Furthermore, there are two exterior rearview mirrors 8, and the second controller 2 can be connected to the electrochromic lenses of each of the two exterior rearview mirrors 8 respectively.

[0119] Furthermore, the above structure is illustrated using the example of a rearview mirror controller that includes both a first controller 1 and a second controller 2, meaning that the rearview mirror has two controllers. However, it should be understood that it is also possible to integrate the functions of the first controller 1 and the second controller 2 into a single structure, i.e., to use only one rearview mirror controller.

[0120] It should also be understood that in this embodiment, the second controller 2 is shared by the controllers of the electrochromic lens of the interior rearview mirror 7 and the electrochromic lens of the exterior rearview mirror 8. This results in a smaller number of parts. It should be understood that it is also possible to match the controllers of the electrochromic lens of the interior rearview mirror 7 and the electrochromic lens of the exterior rearview mirror 8 with separate controllers.

[0121] Input unit Figure 2Although not shown, the input unit is connected to the controller of the rearview mirror. The input unit can be, for example, an existing touch screen on the vehicle. In this embodiment, the input unit can be connected to the first controller 1 or the second controller 2.

[0122] When the input unit is connected to the first controller 1, the input unit inputs a first operation command and a second operation command. The first controller 1 identifies the corresponding command and sends it to the second controller 2. The second controller 2 controls the electrochromic lens of the interior rearview mirror 7 and the electrochromic lens of the exterior rearview mirror 8 respectively. Alternatively, the first controller 1 transmits the first operation command and the second operation command to the second controller 2, and the second controller 2 identifies the corresponding command to adjust the electrochromic lens of the interior rearview mirror 7 and the electrochromic lens of the exterior rearview mirror 8.

[0123] Finally, it should be noted that in this embodiment, the rearview mirror controller simultaneously adjusts the reflectivity of the inner rearview mirror 7 and the outer rearview mirror 8 when the first or second operation command is input. It should be understood that the input unit can be configured to match the inner rearview mirror 7 and the outer rearview mirror 8 respectively.

[0124] For example, there are two input units. Operating one input unit can only adjust the reflectivity of the interior rearview mirror 7, while operating the other input unit can only adjust the reflectivity of the exterior rearview mirror 8. When the number of rearview mirrors varies, the number of input units can be one, or it can be set to a number corresponding to each rearview mirror as needed.

[0125] This embodiment also provides a vehicle, which includes a vehicle controller capable of executing the rearview mirror control method of this embodiment. Specifically, the vehicle controller includes one or more processors and one or more memories.

[0131] This embodiment also relates to a computer-readable storage medium for storing the computer program described above, which, when executed by a processor, implements the rearview mirror control method as described above.

[0132] At this point, a general example of a computer-readable storage medium is a memory. Furthermore, computer-readable storage media include both permanent and non-permanent, removable and non-removable media, and information storage can be achieved by any method or technology.
