Description

[0002] The inner rearview mirror is an important component in the driver's vision system, which can provide the driver with a view of the rear of the vehicle, and is usually used to help the driver observe the road conditions behind and on both sides of the vehicle. The inner rearview mirror can reflect the light of the rear vehicle's headlights. When the vehicle is driving in a relatively dark environment, if the light of the rear vehicle's headlights is too strong, the light reflected by the inner rearview mirror will cause the passengers to be dazzled, affecting the safety of driving.

[0003] To solve this problem, the traditional inner rearview mirror anti-dazzling technology usually adds a light sensor in the inner rearview mirror, and detects the difference in light intensity inside and outside the vehicle through the added light sensor, and then adjusts the reflectivity of the rearview mirror based on the difference in light intensity inside and outside the vehicle to achieve the anti-dazzling function. However, due to the high cost of the light sensor, the production cost of the inner rearview mirror is high. SUMMARY

[0042] To solve the problems in the prior art, the embodiments of the present application provide an interior rearview mirror control method, device, electronic device, vehicle, and storage medium. First, the interior rearview mirror control method provided by the embodiments of the present application is introduced.

[0043] Figure 1 is a flowchart of the interior rearview mirror control method provided by the embodiments of the present application. As shown in Figure 1 The interior rearview mirror control method provided by the embodiments of the present application is applied to a vehicle, and can be specifically applied to an electronic device of the vehicle. For example, the electronic device can be a vehicle terminal. The vehicle includes a headlamp and an interior rearview mirror, and the method includes the following steps 101-102, wherein:

[0044] Step 101, if the headlamp is in an open mode, the target anti-glare degree of the interior rearview mirror is obtained when the gear of the vehicle is in a preset gear and the anti-glare function of the vehicle is turned on, and the preset gear includes any gear except the parking gear and the reverse gear.

[0045] The preset gear includes any gear except the parking gear and the reverse gear, for example, the preset gear can include the neutral gear or the driving gear. The anti-glare function of the vehicle refers to a function of automatically adjusting the intensity of the reflection of the interior rearview mirror to reduce the interference of reflected light on the driver in the night or strong light environment. The anti-glare function of the vehicle can be turned on through the display screen of the vehicle terminal, or can be turned on through the voice control function of the vehicle, or can also be turned on through the keys provided in the vehicle, which is not limited here.

[0046] In a case that the gear of the vehicle is in a preset gear and the anti-dazzling function of the vehicle is turned on, the electronic device can further determine whether the headlamp of the vehicle is in an on mode. If the headlamp is not in the on mode, it can be considered that the environment where the vehicle is located is relatively bright, and the driver of the vehicle is less likely to be disturbed by reflected light, so there is no need to adjust the reflectivity of the interior rearview mirror. If the headlamp is in the on mode, it can be determined that the environment where the vehicle is located is relatively dark, and the driver of the vehicle is more likely to be disturbed by reflected light, so the target anti-dazzling degree of the interior rearview mirror can be obtained, so as to subsequently adjust the reflectivity of the interior rearview mirror according to the target anti-dazzling degree of the interior rearview mirror. The target anti-dazzling degree can be input by a user, can be a default value set in advance, or can also be determined according to historical use records. The target anti-dazzling degree can be in the form of a percentage, such as any percentage in 0-100%, or can be any anti-dazzling degree in a plurality of preset anti-dazzling degrees (for example, 1st-10th anti-dazzling degrees), or the target anti-dazzling degree can also adopt other forms capable of representing the adjustment degree, which is not limited here.

[0047] In step 102, the reflectivity of the interior rearview mirror is adjusted to a target reflectivity according to the target anti-dazzling degree.

[0048] After obtaining the target anti-dazzling degree of the interior rearview mirror, the reflectivity of the interior rearview mirror can be adjusted to a target reflectivity according to the target anti-dazzling degree. Exemplarily, a corresponding relationship between the anti-dazzling degree and the reflectivity can be constructed in advance, that is, a corresponding relationship including a plurality of preset anti-dazzling degrees and the reflectivity corresponding to each preset anti-dazzling degree is constructed. In this way, after obtaining the target anti-dazzling degree, the target anti-dazzling degree can be matched with the plurality of preset anti-dazzling degrees in the corresponding relationship, so as to obtain the target reflectivity corresponding to the target anti-dazzling degree, and then the voltage output to the interior rearview mirror is adjusted according to the target reflectivity, so as to adjust the reflectivity of the interior rearview mirror to the target reflectivity. Alternatively, the value of the voltage to be output to the interior rearview mirror can also be calculated according to the target anti-dazzling degree and the maximum working voltage of the interior rearview mirror, and then the voltage is output to the interior rearview mirror according to the value, so as to adjust the reflectivity of the interior rearview mirror to the target reflectivity. In this way, the adjustment of the reflectivity of the interior rearview mirror can be completed, and the anti-dazzling function of the vehicle can be realized in a case that no light sensor is arranged in the interior rearview mirror.

[0049] The steps 101-102 provided by the embodiment of the present application are that, when the gear of the vehicle is in the preset gear and the anti-dazzling function of the vehicle is turned on, if the headlamp is in the on mode, the target anti-dazzling degree of the inside rearview mirror is acquired, and the reflectivity of the inside rearview mirror is adjusted to the target reflectivity according to the target anti-dazzling degree. Through the above steps, it can be judged whether the reflectivity of the inside rearview mirror needs to be adjusted based on the gear of the vehicle, the on state of the anti-dazzling function and the mode of the headlamp, and the reflectivity of the inside rearview mirror is adjusted when it needs to be adjusted. The light sensor no longer needs to be arranged in the inside rearview mirror, and the production cost of the inside rearview mirror can be reduced.

[0050] In an embodiment of the present application, the inside rearview mirror control method further comprises:

[0051] When the gear of the vehicle is in the parking gear or the reverse gear, the anti-dazzling function of the vehicle is disabled.

[0052] When the gear of the vehicle is in the parking gear or the reverse gear, the driver may have the need to observe the road conditions behind the vehicle through the inside rearview mirror, at this time, the reflectivity of the inside rearview mirror needs to be high so that the driver can clearly observe the situation behind the vehicle. Therefore, when the gear of the vehicle is in the parking gear or the reverse gear, the anti-dazzling function of the vehicle can be disabled, so that the anti-dazzling function of the vehicle cannot be turned on, avoiding interference with the driver observing the road conditions behind the vehicle through the inside rearview mirror, and improving the safety of using the vehicle.

[0053] In an embodiment of the present application, the target anti-dazzling degree adopts a preset default value, or is determined according to historical use records, or is determined based on user input, and the historical use records are used to record the anti-dazzling degrees used by the inside rearview mirror in a historical time period.

[0054] Specifically, when the gear of the vehicle is in the preset gear, the anti-dazzling function of the vehicle is turned on, and the headlamp is in the on mode, the target anti-dazzling degree of the inside rearview mirror can be acquired. The target anti-dazzling degree can be a preset default value (such as 50%). For example, when the anti-dazzling function of the vehicle is used for the first time, the default value can be used as the target anti-dazzling degree. Alternatively, the target anti-dazzling degree can be determined according to historical use records. The historical use records are used to record the anti-dazzling degrees used by the inside rearview mirror in a historical time period, and the historical time period is determined based on the current time and a preset time length, which can be adjusted according to actual conditions. The current time refers to the time when the target anti-dazzling degree is acquired.

[0055] For example, if the anti-dazzling function of the vehicle is re-enabled, the gear of the vehicle is in the preset gear, and the headlamp is in the on mode, the target anti-dazzling degree can be determined according to the historical use record when no user input is received. In addition, if the gear of the vehicle is switched to the preset gear or the headlamp is switched to the on mode, the target anti-dazzling degree can also be determined according to the historical use record. Alternatively, the target anti-dazzling degree can be determined based on user input. The user input can be input by the user through the display screen of the vehicle terminal, input by the user through the voice control function of the vehicle, or input through the buttons or knobs provided in the vehicle, which is not limited herein. In this way, the target anti-dazzling degree can be obtained in various ways, so as to adjust the reflectivity of the interior rearview mirror based on the target anti-dazzling degree subsequently.

[0056] In an embodiment of the present application, the interior rearview mirror is made of electrochromic material, and the on mode includes a low beam mode or a high beam mode.

[0057] The reflectivity of the interior rearview mirror is adjusted to a target reflectivity according to the target anti-dazzling degree, including:

[0058] The maximum working voltage of the interior rearview mirror corresponding to the on mode is obtained, wherein the maximum working voltage corresponding to the low beam mode is less than the maximum working voltage corresponding to the high beam mode;

[0059] The target voltage of the interior rearview mirror is determined according to the maximum working voltage and the target anti-dazzling degree;

[0060] The voltage of the interior rearview mirror is adjusted to the target voltage to adjust the reflectivity of the interior rearview mirror to the target reflectivity.

[0061] According to the target anti-dazzling degree, the reflectivity of the interior rearview mirror can be adjusted to the target reflectivity. Specifically, the interior rearview mirror is made of electrochromic material (such as electrochromic glass). Under the action of an electric field, the ions in the electrochromic material of the interior rearview mirror can move directionally, so that the optical absorption characteristics of the interior rearview mirror change reversibly, and specifically, the color of the interior rearview mirror changes.

[0062] Based on the foregoing features of the interior rearview mirror, the reflectivity of the interior rearview mirror can be adjusted by changing the voltage output to the interior rearview mirror. The on mode includes a low beam mode or a high beam mode. First, the electronic device can obtain the maximum working voltage of the interior rearview mirror corresponding to the on mode. It can be understood that, compared to the environment in which the vehicle is located when the headlamp is in the low beam mode, the environment in which the vehicle is located when the headlamp is in the high beam mode is usually darker, and at this time the driver of the vehicle is more likely to be disturbed by the strong light of other vehicles, so the reflectivity of the interior rearview mirror when the headlamp is in the high beam mode should be lower than the reflectivity of the interior rearview mirror when the headlamp is in the low beam mode, in order to reduce the reflection of light. And the voltage output to the interior rearview mirror is negatively correlated with the reflectivity of the interior rearview mirror. Therefore, the maximum working voltage corresponding to the low beam mode should be less than the maximum working voltage corresponding to the high beam mode.

[0063] Thus, according to the maximum working voltage and the target anti-glare degree, the target voltage of the interior rearview mirror can be determined. For example, if the target anti-glare degree is any anti-glare degree in the plurality of anti-glare degrees preset, then based on the maximum working voltage, the voltage corresponding to each anti-glare degree can be determined. For example, the maximum working voltage is 1.2 volts, and the anti-glare degrees of 1 to 10 are preset, then the voltage corresponding to the anti-glare degree of 1 can be 0.12 volts, the voltage corresponding to the anti-glare degree of 10 can be 1.2 volts, and so on. Thus, after obtaining the target anti-glare degree, the voltage corresponding to the target anti-glare degree, i.e. the target voltage, can be determined. Alternatively, if the target anti-glare degree is in percentage form, for example 50%, then in the case of a maximum working voltage of 1.2 volts, the target anti-glare degree can be multiplied by the maximum working voltage to obtain the target voltage of the interior rearview mirror, i.e. 0.6 volts. It should be noted that the determination of the maximum working voltage of the interior rearview mirror corresponding to the on mode, and the target voltage of the interior rearview mirror is not limited to the foregoing examples, and can be adjusted according to actual conditions.

[0064] After obtaining the target voltage of the interior rearview mirror, the voltage output to the interior rearview mirror can be adjusted to the target voltage to adjust the reflectivity of the interior rearview mirror to the target reflectivity. Specifically, the duty cycle of the pulse width modulation signal can be adjusted to make the voltage output to the interior rearview mirror reach the target voltage. Thus, under the action of the target voltage, the ions in the electrochromic material of the interior rearview mirror move directionally, causing the optical performance of the interior rearview mirror to change, and the reflectivity of the interior rearview mirror to adjust to the target reflectivity. Through the foregoing steps, the reflectivity of the interior rearview mirror can be adjusted to the target reflectivity according to the target anti-glare degree, thereby completing the adjustment of the reflectivity of the interior rearview mirror and realizing the anti-glare function of the vehicle.

[0065] In an embodiment of the present application, the method further comprises:

[0066] multiplying the maximum working voltage and the target anti-dazzling degree to obtain the target voltage of the interior rearview mirror, the target anti-dazzling degree being greater than or equal to 0 and less than or equal to 1.

[0067] According to the maximum working voltage and the target anti-dazzling degree, the target voltage of the interior rearview mirror can be determined. Specifically, the target anti-dazzling degree is a specific value that can describe the ratio between the target voltage and the maximum working voltage, and the target anti-dazzling degree is greater than or equal to 0 and less than or equal to 1, for example, the target anti-dazzling degree can be 50% or 0.5. In this way, the maximum working voltage and the target anti-dazzling degree can be multiplied to obtain the target voltage of the interior rearview mirror. For example, the maximum working voltage is 1.2 volts, and the target anti-dazzling degree is 50%, and the target voltage can be obtained as 0.6 volts. Through the foregoing steps, the target voltage to be output to the interior rearview mirror can be determined, which facilitates subsequent output of the target voltage to the interior rearview mirror, so that the reflectivity of the interior rearview mirror can be adjusted to the target reflectivity.

[0068] In an embodiment of the present application, after the reflectivity of the interior rearview mirror is adjusted to the target reflectivity according to the target anti-dazzling degree, the method further comprises:

[0069] performing preset processing on the target anti-dazzling degree to obtain usage information of the target anti-dazzling degree, the usage information comprising at least one of the number of times of usage of the target anti-dazzling degree and the usage time of the target anti-dazzling degree;

[0070] the preset processing comprises one of the following:

[0071] if there is an anti-dazzling degree same as the target anti-dazzling degree in the historical usage record, the number of times of usage of the anti-dazzling degree same as the target anti-dazzling degree in the historical usage record is increased by one to obtain the number of times of usage of the target anti-dazzling degree, and / or the usage time of the target anti-dazzling degree is recorded in the historical usage record, the historical usage record being used to record the anti-dazzling degrees used by the interior rearview mirror in a historical time period;

[0072] if there is no anti-dazzling degree same as the target anti-dazzling degree in the historical usage record, the target anti-dazzling degree is recorded in the historical usage record, and the number of times of usage of the target anti-dazzling degree is recorded, and / or the usage time of the target anti-dazzling degree is recorded in the historical usage record.

[0073] The use information includes at least one of a use frequency and a use time of the target glare degree. The use time can be a start time of using the target glare degree, or the use time can be an end time of using the target glare degree, or the use time can be a time period from the start time to the end time of using the target glare degree. After the reflectivity of the interior rearview mirror is adjusted to the target reflectivity according to the target glare degree, the target glare degree can be preset to obtain the use information of the target glare degree.

[0074] Specifically, based on the target glare degree and the glare degrees recorded in the historical use record, a processing manner for the target glare degree can be determined. The historical use record can be used to record the glare degrees used by the interior rearview mirror in a historical time period. That is, if there is a glare degree same as the target glare degree in the historical use record, the use frequency of the glare degree same as the target glare degree in the historical use record is increased by one to obtain the use frequency of the target glare degree, and / or the use time of using the target glare degree is recorded in the historical use record. For example, if the target glare degree is 50%, and there is a glare degree same as the target glare degree (i.e. 50%) in the historical use record, the use frequency of the glare degree same as the target glare degree (e.g. 3 times) can be obtained from the historical use record, then the use frequency of the glare degree same as the target glare degree is increased by one to obtain the use frequency of the target glare degree (i.e. 4 times), and the historical use record is updated according to the use frequency of the target glare degree. If there is no glare degree same as the target glare degree in the historical use record, the target glare degree is recorded in the historical use record, and the use frequency of the target glare degree is recorded, and / or the use time of using the target glare degree is recorded in the historical use record. In this way, the use information of the target glare degree can be recorded in the historical use record as historical use information, so as to determine the target glare degree based on the information recorded in the historical use record subsequently.

[0075] It should be noted that subsequently, if it is necessary to determine the target glare degree according to the historical use record, the target glare degree can be determined based on the use frequency of each glare degree or the use time of each glare degree. For example, the glare degree with the highest use frequency can be determined as the target glare degree. Or, the glare degree with the closest use time to the current time can be determined as the target glare degree. Or, if the use time is a time period, the glare degree with the longest use time can be determined as the target glare degree.

[0076] The following provides an example of the rearview mirror control method provided in the embodiments of this application.

[0077] Figure 2 This is a schematic diagram of the communication relationships within a vehicle provided in an embodiment of this application. Currently, vehicles generally possess... Figure 2 The basic subsystem and domain controller 4 (i.e., electronic device) shown can achieve the rearview mirror anti-glare solution provided in this application embodiment without using a light sensor by adding software signals, without changing the hardware such as the interface and pins of the domain controller 4.

[0078] like Figure 2 As shown, the basic subsystem includes a lighting subsystem 1, a gear shift subsystem 2, and a vehicle infotainment subsystem 3 (i.e., the vehicle terminal). The lighting subsystem 1 provides a signal indicating whether the vehicle's headlights are on. The gear shift subsystem 2 provides a signal indicating the vehicle's gear position. The vehicle infotainment subsystem 3 provides a switch to enable / disable the anti-glare function, and also allows the user to input the target anti-glare level. The domain controller 4 processes the signals provided by the lighting subsystem 1, gear shift subsystem 2, and vehicle infotainment subsystem 3, and outputs a target voltage corresponding to the target anti-glare level to the rearview mirror 5.

[0079] The rearview mirror 5, acting as the execution terminal of the entire anti-glare mechanism, uses a special electrochromic material in its lens, such as electrochromic glass. Electrochromic materials possess the characteristic of changing their light transmittance under different electric fields, and their transmittance is continuously adjustable. Therefore, when the rearview mirror 5 receives the target voltage output from the domain controller 4, the ions within the electrochromic material of the rearview mirror 5 will undergo directional movement under the drive of the electric field, thereby changing the optical performance of the rearview mirror 5 (i.e., changing the reflectivity of the rearview mirror 5) and causing a change in the color of the rearview mirror 5.

[0080] In the process of processing the signals provided by the lighting subsystem 1, gear shift subsystem 2, and vehicle infotainment subsystem 3 through the domain controller 4, the following conditions can be determined based on the signals provided by the lighting subsystem 1, gear shift subsystem 2, and vehicle infotainment subsystem 3:

[0081] Condition 1: Whether the vehicle's headlights are in the on mode (provided by lighting subsystem 1);

[0082] Condition 2: Is the vehicle not in park or reverse gear (provided by gear position subsystem 2)?

[0083] Condition 3: Is the vehicle's anti-glare switch turned on? (Signal provided by vehicle infotainment system 3)

[0084] The condition one is used to determine whether the current vehicle is in an environment with relatively dark external light (such as a night road, a tunnel, an underground parking lot, etc.); the condition two is used to determine whether the current vehicle is in normal driving, and when the vehicle is in a parking gear or a reverse gear, the anti-dazzling function can be disabled to avoid affecting the driver's behavior of observing the rear of the vehicle through the interior rearview mirror; and the condition three is used to determine whether the driver currently needs to turn on the anti-dazzling function.

[0085] When the above three conditions are met, that is, the gear of the vehicle is in a preset gear (wherein the preset gear includes any gear except the parking gear and the reverse gear), the anti-dazzling function of the vehicle is turned on, and the headlamp is in an on mode, the domain controller 4 determines that the vehicle needs to be anti-dazzled, and at this time, the domain controller 4 will output a target voltage by changing the duty cycle of the pulse width modulation signal according to the target anti-dazzling degree provided by the vehicle machine subsystem 3. That is, when the user sets a higher target anti-dazzling degree, the domain controller 4 will adjust the pulse width modulation signal, so that the duty cycle of the pulse width modulation signal becomes larger, thereby applying a higher target voltage to the interior rearview mirror 5 to enhance the anti-dazzling effect of the interior rearview mirror 5 (at this time, the decrease value of the reflectivity of the interior rearview mirror 5 is larger). Conversely, when the user sets a lower target anti-dazzling degree, the domain controller 4 will adjust the pulse width modulation signal, so that the duty cycle of the pulse width modulation signal becomes smaller, thereby reducing the target voltage applied to the interior rearview mirror 5 to weaken the anti-dazzling effect of the interior rearview mirror 5 (at this time, the decrease value of the reflectivity of the interior rearview mirror 5 is smaller).

[0086] In addition, when the user uses the anti-dazzling function for the first time, the vehicle machine subsystem 3 can provide a default factory degree (i.e., a pre-set default value) as the target anti-dazzling degree, such as 50%, so that even if the user uses the anti-dazzling function for the first time, the color change effect of the interior rearview mirror 5 can be perceived. In other cases, the user can set the target anti-dazzling degree through the vehicle machine subsystem 3 according to the environment in which the vehicle is located and subjective feeling. Moreover, the target anti-dazzling degree set by the user can be memorized by the vehicle machine subsystem 3, and when the anti-dazzling function is turned on next time, the vehicle machine subsystem 3 can provide the target anti-dazzling degree set by the user last time, so that the domain controller 4 adjusts the reflectivity of the interior rearview mirror 5 according to the target anti-dazzling degree set by the user last time. In this way, the user does not need to set the target anti-dazzling degree again, and can also avoid the situation that the user cannot achieve the required anti-dazzling effect again due to forgetting the specific value of the set target anti-dazzling degree.

[0087] Compared with the prior art, the interior rearview mirror control method provided by the embodiment of the present application has the following advantages:

[0088] (1) The interior rearview mirror does not have a light sensor or a complex electronic system, which reduces the risk of the anti-glare function failing due to electronic component failure, and allows the interior rearview mirror to stably play the role of reducing strong light interference in various harsh environments.

[0089] (2) By adding a manual adjustment option, the driver can decide whether to activate the anti-glare function based on their actual experience, and can also adjust the anti-glare level independently. In this way, it is not limited by the preset program and sensing range of the light sensor, and can more accurately meet the driver's personal anti-glare needs. This allows the driver to flexibly adjust the reflectivity of the rearview mirror according to the intensity of the lights of vehicles behind them under different road conditions and lighting conditions, thereby achieving the best anti-glare effect.

[0090] (3) The vehicle terminal can memorize the target anti-glare level set by the user. In this way, if the vehicle is still in a low light environment when the user disconnects from the vehicle and gets back in, the anti-glare level can be automatically restored to the level set before the user disconnected from the vehicle, without the need for the user to adjust it again, thus improving the user experience.
