[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] With the development and progress of related electronic imaging technologies and vehicle intelligence, car rearview mirrors are also undergoing an intelligent transformation. Currently, most electronic exterior rearview mirrors have a defogging function, which mainly uses lens heating or physical wiping to remove fog and frost.

[0027] In the first related technology, as shown in Figure 1, the defogging vehicle-mounted camera includes: a lens module 110; a heating ring 120, which is mounted on the lens module 110 and used to heat the lens module 110; a heating control module 130, electrically connected to the heating ring 120, which controls the output power of the heating ring 120; a temperature protection module 140, electrically connected to both the heating ring 120 and the heating control module 130, which checks the ambient temperature of the heating ring 120 and sends an interrupt heating command to the heating control module 130 when the ambient temperature exceeds a preset temperature value; a current detection auxiliary module 150, electrically connected to the heating ring 120, which detects the heating current of the heating ring 120; and a current limiting protection module 160, electrically connected to both the current detection auxiliary module 150 and the heating control module 130, which limits the current of the heating control module 130 when the heating current exceeds a preset current value.

[0028] In the second related technology, as shown in FIG. 2, the front shell 2 is fixedly connected with the rear shell 1, and a PCB board 7 is fixedly installed in the front shell 2, and a photosensitive chip 8 is arranged on the PCB board 7, and a plug-in connector 5 for electrically connecting a vehicle body is fixedly connected to the rear shell 1, and a lens shell 3 is fixedly connected to the front shell 2, and a mounting block 11 is fixedly connected in the lens shell 3, and a camera lens 6 is fixedly connected in the middle of the mounting block 11, and the camera lens 6 faces the photosensitive chip 8, and a slidable protective lens is arranged on the mounting block 11, and a lens cover body 4 is fixedly connected to the lens shell 3, and a through hole adapted to the camera lens 6 is arranged on the lens cover body 4, the protective lens is in a strip shape, and the inner side of the protective lens is connected to the camera lens 6, and the outer side of the protective lens is connected to the lens cover body 4, a driving mechanism for driving the protective lens to slide is arranged on the mounting block 11, and a heating element 10 corresponding to the protective lens is also fixedly connected to the mounting block 11 on both sides of the camera lens 6. The defogging method comprises: a camera lens 6 side heating module, a protective lens driving mechanism, the strip-shaped protective lens is driven to slide by the driving mechanism, and then the fogging or frosting part is moved, and the part without fogging or frosting is located in the opposite range of the through hole, and the method has a certain degree of anti-fogging effect.

[0029] The inventor finds that in the first related technology, the defogging vehicle-mounted camera heats the lens surface longitudinally, and the defrosting and defogging efficiency is slow, and long-time heating can easily cause damage to the lens. The defogging detection method based on image detection is easy to cause the defogging heating instruction to be mis-triggered when the camera focuses due to blurred imaging. In the second related technology, the front lens is movable, which causes poor sealing between the camera lens 6 and the light-transmitting lens, and is easy to cause the camera lens 6 to fog inside and cannot be defogged; and the movable lens is easy to scratch the lens, thereby affecting the imaging of the camera.

[0030] Therefore, the present disclosure provides an electronic rearview mirror and a control method, a vehicle, a storage medium and a program product to solve the technical problems in the above related technologies.

[0031] As shown in FIG. 3, FIG. 3 is a schematic diagram of an electronic rearview mirror according to an example embodiment of the present disclosure, referring to FIG. 3, comprising a camera device, a light-transmitting lens 303 and a heating module 304, a lens 305 in the camera device and the light-transmitting lens 303 form a sealed space, and the sealed space is filled with a medium;

[0032] The heating module 304 is used for heating the medium in the sealed space to remove the fog on the light-transmitting lens 303 and / or the lens 305 in the camera device through the heated medium.

[0033] By the technical solution, the medium is filled in the sealed space formed between the lens 305 and the light-transmitting lens 303, and the lens 305 and / or the light-transmitting lens 303 in the camera is removed of the fog by heating the medium by the heating module 304. Compared with the related art, the lens 305 and / or the light-transmitting lens 303 is not directly heated, the damage of the lens 305 and / or the light-transmitting lens 303 is reduced, the fog removal efficiency is improved, and the lens 305 and / or the light-transmitting lens 303 is prevented from being scratched.

[0034] In order to make the person skilled in the art more understand the electronic rearview mirror provided by the present disclosure, the above modules are described in detail below.

[0035] For example, as shown in FIG. 3, the camera can include a lens 305, an image sensor 306, a camera interface 307, a first controller 310, and a display 309 in the vehicle. The camera interface 307 connects the output end of the image sensor 306 and the input end of the first controller 310, and the output end of the first controller 310 is connected with the display screen.

[0036] The lens 305 can be combined by a mirror, a transmitting lens, and a prism in a certain way, and the light image of the observed target can be presented on the target surface of the camera, and finally imaged on the display 309. The image sensor 306 can be a photosensitive element, and can convert the image transmitted by the lens 305 into an electrical signal on the photosensitive surface in a corresponding proportional relationship, and transmit the electrical signal to the display 309 through the first controller 310. The first controller 310 can be used to comprehensively process the reference data collected by each sensor, receive the reference data and fuse, and can transmit data and control instructions to the camera, the second controller 308, the memory 311 and the display 309. The camera interface 307 can be used to connect the image sensor 306 and the first controller 310. The first controller 310 can supply power to the image sensor 306 through the camera interface 307, the image sensor 306 can transmit the detected real-time image to the first controller 310 through the camera interface 307, and the first controller 310 can also transmit other control sub-signals to the camera interface 307. The display 309 can be placed in the vehicle or on a terminal device, used to display the image transmitted by the image sensor 306, and used for the driver or the member to observe the road conditions. The terminal device can be a mobile phone, a tablet computer, a computer, and the like.

[0037] The light-transmitting lens 303 can be a high-definition lens, which is used to enable the camera to collect surrounding environment image information through the light-transmitting lens 303, and can play a role of waterproofing, dustproofing, and preventing overexposure for the lens 305, so as to ensure that the field of view of the lens 305 is clear and stable. In the electronic rearview mirror, the lens 305 of the camera can be used to capture and focus light, and the light-transmitting lens 303 can ensure that the light passes through the lens 305 to the image sensor 306 as much as possible without loss. The heating module 304 can be used to heat the medium in the sealed space. The heating module 304 can be a heating resistor 403, an electric heating wire, or a heater, which is not limited in the embodiment of the present disclosure. The electronic rearview mirror can be an electronic outside rearview mirror, which is not limited in the embodiment of the present disclosure.

[0038] The electronic rearview mirror is used to replace the traditional mirror rearview mirror, and the imaging advantage of the camera is used to reduce the blind area of the rearview mirror, so as to improve the driving safety. At the same time, after the traditional rearview mirror is cancelled, the wind area of the vehicle can be reduced, and then the wind resistance can be reduced, and the fuel consumption and the power consumption of the vehicle can be reduced.

[0039] In the embodiment, the lens 305 of the camera and the light-transmitting lens 303 form a sealed space, and the medium is filled in the sealed space. The medium can be a gaseous medium or a liquid medium, which is not limited in the embodiment of the present disclosure. As shown in FIG. 4, the filled medium is located between the lens mounting position 402 and the light-transmitting lens mounting position 401.

[0040] Then, the medium can be heated by the heating module 304, and the fog on the lens 305 and / or the light-transmitting lens 303 can be removed through the heated medium. The fog on the lens 305 and / or the light-transmitting lens 303 can be removed by heating the medium through the heating module 304, which can achieve the effect of removing the fog, and can avoid directly heating the lens 305 and / or the light-transmitting lens 303, so as to reduce the damage of the lens 305 and / or the light-transmitting lens 303, and reduce the situation that the lens 305 and / or the light-transmitting lens 303 is scratched.

[0041] In a possible manner, the heating module 304 is arranged at a target position of the sealed space, and the target position is a position that does not block the lens 305 and the light-transmitting lens 303.

[0042] For example, the target position can be a side wall of the closed space or an outer side of the closed space. When the target position is a side wall of the closed space, the medium in the closed space can be heated directly by the heating module 304. When the target position is an outer side of the closed space, the medium heated by the heating module 304 can be input into the closed space to defog the lens 305 and / or the light-transmitting lens 303. In this way, the heating of the medium by the heating module 304 arranged at the target position can avoid the obstruction of the field of view of the lens 305 and / or the light-transmitting lens 303.

[0043] In a possible implementation, the heating module 304 includes a heating resistor 403 and a circuit board 404, and the heating resistor 403 is arranged on the circuit board 404.

[0044] The heating module 304 is configured to heat the medium in the closed space by the heating resistor 403.

[0045] It should be understood that the heating resistor 403 can be a conductor that generates heat when powered. The circuit board 404 can be an aluminum substrate, which is not limited in the embodiments of the present disclosure. The aluminum substrate can be a metal-based copper-clad plate with good heat dissipation function.

[0046] As shown in FIG. 4, the heating module 304 includes a heating resistor 403 and a circuit board 404, and the heating resistor 403 is arranged on the circuit board 404. The heating resistor 403 can be arranged in one or multiple. When the heating resistor 403 is arranged in multiple, the heating resistors 403 can be arranged in sequence on the circuit board 404. The circuit board 404 can be arranged at the target position of the closed space, so as to avoid the obstruction of the light of the lens 305 and the light-transmitting lens 303.

[0047] In a possible implementation, the medium is an inert gas medium, and the inert gas medium includes helium and argon.

[0048] It should be understood that when the medium is a gas medium, the gas medium can be an inert gas medium. Among them, the inert gas medium can include helium and argon, and the embodiments of the present disclosure do not make specific limitations thereon. Helium is a lighter inert gas than air, with a boiling point of -268.93°C, and has the characteristics of lower boiling point and can be rapidly heated and penetrate small spaces. Argon is a heavier inert gas than air, with a boiling point of -185.85°C, and has the characteristic of higher boiling point, and the gas can provide uniform heat distribution, so it can be suitable for scenarios that require a larger heating area. At the same time, helium and argon also have good insulation performance, which can help prevent heat loss. That is to say, when helium and argon are filled in the closed space, the helium and argon filled in the closed space can be rapidly and uniformly heated by the heating module 304, thereby improving the defogging rate and uniformity of the lens 305 and / or the light-transmitting lens 303.

[0049] By heating the medium with the heating module 304 to remove the fog on the lens 305 and / or the light-transmitting lens 303 in the camera, compared with the way of directly defogging the lens 305 or the light-transmitting lens 303 in the related art, it can avoid directly heating the lens 305 and / or the light-transmitting lens 303, thereby reducing the damage to the lens 305 and / or the light-transmitting lens 303, and also preventing the lens 305 and / or the light-transmitting lens 303 from being scratched.

[0050] In a possible manner, the electronic rearview mirror further includes a control unit, a temperature sensor 302, and / or a humidity sensor 301, an output end of the temperature sensor 302 is connected to an input end of the control unit, an output end of the humidity sensor 301 is connected to an input end of the control unit, and an output end of the control unit is connected to the heating module 304.

[0051] The temperature sensor 302 is configured to detect a temperature value of the medium in the closed space and transmit the temperature value to the control unit.

[0052] The humidity sensor 301 is configured to detect a humidity value outside the light-transmitting lens 303 and transmit the humidity value to the control unit.

[0053] The control unit is configured to control a working state of the heating module 304 according to the temperature value and / or the humidity value.

[0054] It should be understood that the temperature sensor 302 can be a sensor that converts a temperature variable into a standardized output signal that can be transmitted. The humidity sensor 301 can be a sensor that converts a humidity variable into a standardized output signal that can be transmitted. The control unit can be a device for controlling the working state of the heating module 304.

[0055] In the embodiment, the temperature sensor 302 can collect the temperature value of the medium in the sealed space and transmit the temperature value to the control unit. The humidity sensor 301 can collect the humidity value outside the light-transmitting lens 303 and transmit the humidity value to the control unit. The control unit can control the working state of the heating module 304 according to the temperature value and / or the humidity value. For example, the control unit can control whether the heating module 304 enters the heating state according to the temperature value and the humidity value. Alternatively, the control unit can control whether the heating module 304 is in the stop heating state according to the temperature value and / or the humidity value, which is not limited in the embodiment of the present disclosure.

[0056] When the control unit controls the working state of the heating module 304 according to the temperature value and / or the humidity value, the temperature value and the humidity value can be used to determine the starting and stopping time of the heating module 304, which can improve the accuracy of controlling the working state of the heating module 304, and thus can improve the defogging efficiency and reduce the loss.

[0057] In a possible manner, the humidity sensor 301 is arranged outside the light-transmitting lens 303, and / or

[0058] The temperature sensor 302 is arranged in the medium in the sealed space.

[0059] It should be understood that when the temperature of the medium in the sealed space is measured by the temperature sensor 302, the temperature sensor 302 can be arranged on the side wall in the sealed space, which is not limited in the embodiment of the present disclosure. When the humidity value of the environment where the electronic rearview mirror is located is measured by the humidity sensor 301, the humidity sensor 301 can be arranged outside the light-transmitting lens 303, which is not limited in the embodiment of the present disclosure.

[0060] By arranging the temperature sensor 302 in the sealed space to measure the temperature value of the medium in the sealed space and arranging the humidity sensor 301 outside the light-transmitting lens 303 to measure the humidity value of the environment where the electronic rearview mirror is located, the working state of the heating module 304 can be controlled according to the temperature value and / or the humidity value, and thus the defogging efficiency can be improved and the loss can be reduced.

[0061] In a possible manner, the control unit is configured to:

[0062] When the temperature value is less than a preset temperature value and the humidity value is greater than a preset humidity value, the control unit controls the heating module 304 to be in the heating state, the preset temperature value is the temperature value of the electronic rearview mirror in the state without fog, and the preset humidity value is the humidity value of the electronic rearview mirror in the state without fog.

[0063] It should be understood that the preset temperature value can be a temperature value when the enclosed space formed between the lens 305 and the light-transmitting lens 303 is in a state without fog. The preset humidity value can be a humidity value when the enclosed space formed between the lens 305 and the light-transmitting lens 303 is in a state without fog. When the temperature value is less than the preset temperature value and the humidity value is greater than the preset humidity value, it can represent that the enclosed space formed between the lens 305 and the light-transmitting lens 303 is fogging, and de-fogging is needed in time. In this case, the heating module 304 can be controlled to be in a heating state, and then the medium in the enclosed space is heated by the heating module 304, and the fog on the lens 305 and / or the light-transmitting lens 303 is removed by the heated medium.

[0064] By setting the preset temperature value and the preset humidity value, and controlling the heating state of the heating module 304 according to the temperature value, the preset temperature value, the humidity value and the preset humidity value, the sensitivity and accuracy of the de-fogging of the heating module 304 can be improved.

[0065] In a possible manner, the control unit is configured to:

[0066] After the heating module 304 is controlled to be in the heating state, when the temperature value is greater than the preset temperature value, and / or the humidity value is less than the preset humidity value, the heating module 304 is controlled to be in a stop heating state.

[0067] It should be understood that when the working state of the heating module 304 is in the heating state, the temperature value in the medium and the humidity value outside the light-transmitting lens 303 can continue to be collected, and then the heating module 304 can be controlled to be in the stop heating state according to the temperature value and / or the humidity value. For example, when the temperature value is greater than the preset temperature value, or the humidity value is less than the preset humidity value, or the temperature value is greater than the preset temperature value and the humidity value is less than the preset humidity value, the heating module 304 can be controlled to be in the stop heating state.

[0068] By continuing to collect the temperature value and / or the humidity value, and comparing the temperature value with the preset temperature value, and / or comparing the humidity value with the preset humidity value, the heating module 304 can be controlled to be in the stop heating state. Damage caused by overheating of the heating module 304 can be prevented.

[0069] In a possible manner, the control unit is further configured to:

[0070] Obtain meteorological environment data of an environment in which the electronic rearview mirror is located, and determine the preset temperature value and the preset humidity value according to the meteorological environment data.

[0071] It should be understood that the preset temperature value and the preset humidity value can be determined according to meteorological environment data of an environment in which the vehicle is located. For example, when the vehicle travels from a place A to a place B, and the meteorological environment data of the place A and the place B are different, the preset temperature value and the preset humidity value of the place A and the place B are also different. By determining the preset temperature value and the preset humidity value according to the meteorological environment data of the environment in which the vehicle is located, the preset temperature value and the preset humidity value can be updated adaptively, and then the starting and stopping time of the heating module 304 can be determined according to the preset temperature value and the preset humidity value, which can improve the accuracy of defogging and improve the defogging efficiency and reduce the loss.

[0072] In a possible manner, the control unit includes a first controller 310 and a second controller 308, an input end of the first controller 310 is connected with an output end of the temperature sensor 302 and / or an output end of the humidity sensor 301 respectively, an output end of the first controller 310 is connected with an input end of the second controller 308, and an output end of the second controller 308 is connected with the heating module 304;

[0073] The first controller 310 is configured to receive the temperature value and / or the humidity value, and generate a control signal according to the temperature value and / or the humidity value, and input the control signal to the second controller 308.

[0074] The second controller 308 is configured to control the working state of the heating module 304 according to the control signal.

[0075] It should be understood that the second controller 308 can be a heating controller, which can be configured to receive the control signal sent by the first controller 310, and then control the working state of the heating module 304 according to the control signal. For example, when the temperature value exceeds the preset temperature value, the heating module 304 is controlled to be in a stopping heating state, and over-temperature protection can be realized.

[0076] The control signal can be a defogging instruction, a stop heating instruction, etc. When the second controller 308 receives the control signal, it can control the working state of the heating module 304 according to the control signal. For example, as shown in FIG. 5, when the first controller 310 determines that the temperature value is less than the preset temperature value and the humidity value is greater than the preset humidity value, the generated control signal can be a defogging instruction, and the defogging instruction is sent to the second controller 308. After receiving the defogging instruction, the second controller 308 controls the heating module 304 to enter a heating state, so as to remove the fog on the lens 305 and / or the light-transmitting lens 303 by heating the medium. When the first controller 310 determines that the temperature value is greater than the preset temperature value and / or the humidity value is less than the preset humidity value, the generated control signal can be a stop heating instruction, and the stop heating instruction is sent to the second controller 308. After receiving the stop heating instruction, the second controller 308 can control the heating module 304 to be in a stop heating state, thereby achieving over-temperature protection.

[0077] As shown in FIG. 3, the electronic rearview mirror further includes a power supply 312 and a memory 311. The output end of the power supply 312 can be connected with the first controller 310, the memory 311, the display 309 and the second controller 308 of the electronic rearview mirror, for supplying power to the first controller 310, the memory 311, the display 309 and the second controller 308. The memory 311 can be used to store the data of each sensor received by the first controller 310 and the data information displayed on the display 309.

[0078] Based on the same concept, the embodiment also discloses a control method of an electronic rearview mirror. The electronic rearview mirror includes a camera device, a light-transmitting lens 303 and a heating module 304. The lens 305 of the camera device and the light-transmitting lens 303 form a sealed space, and the sealed space is filled with a medium. As shown in FIG. 6, which is a schematic diagram of a control method of an electronic rearview mirror according to an example embodiment of the present disclosure, the control method includes:

[0079] S601: Control the heating module 304 to heat the medium in the sealed space, so as to remove the fog on the light-transmitting lens 303 and / or the lens 305 of the camera device by the heated medium.

[0080] For example, when the heating module 304 is controlled to heat the medium in the sealed space, the control can be performed by a control unit, and the present embodiment does not make specific limitation thereto.

[0081] Optionally, the control method further includes:

[0082] Detecting the humidity value outside the light-transmitting lens 303 and / or the temperature value of the medium in the sealed space.

[0083] According to the temperature value and / or the humidity value, the working state of the heating module 304 is controlled.

[0084] Optionally, according to the temperature value and the humidity value, the working state of the heating module 304 is controlled, including:

[0085] When the temperature value is less than a preset temperature value, and the humidity value is greater than a preset humidity value, the heating module 304 is controlled to be in a heating state, the preset temperature value is a temperature value of the electronic rearview mirror in a state without fog, and the preset humidity value is a humidity value of the electronic rearview mirror in the state without fog.

[0086] Optionally, according to the temperature value and / or the humidity value, the working state of the heating module 304 is controlled, including:

[0087] After the heating module 304 is controlled to be in the heating state, when the temperature value is greater than the preset temperature value, and / or the humidity value is less than the preset humidity value, the heating module 304 is controlled to be in a stop heating state.

[0088] The control method further includes:

[0089] Obtaining meteorological environment data of an environment in which the electronic rearview mirror is located;

[0090] According to the meteorological environment data, the preset temperature value and the preset humidity value are determined.

[0091] Referring to FIG. 7, FIG. 7 is a flowchart illustrating a control method of an electronic rearview mirror according to an example embodiment of the present disclosure. As shown in FIG. 7, the flow of the control method of the electronic rearview mirror includes the following steps.

[0092] S701: When a vehicle is started, the electronic rearview mirror can obtain a temperature value in a sealed space through a temperature sensor 302, and obtain a humidity value outside a light-transmitting lens 303 through a humidity sensor 301.

[0093] S702: A preset temperature value and a preset humidity value are generated by a first controller 310 according to current meteorological environment data.

[0094] S703: The temperature value, the preset temperature value, the humidity value, and the preset humidity value are fused by the first controller 310, and when the temperature value is lower than the preset temperature value, and the humidity value is greater than the preset humidity value, a control signal of a defogging instruction is generated.

[0095] S704: When the heating controller receives the control signal, the current input to the heating module 304 is controlled to make the heating module 304 enter a heating state, so that the medium in the sealed space between the camera lens 305 and / or the light-transmitting lens 303 is heated by the heating module 304, and the lens 305 and the light-transmitting lens 303 are defogged.

[0096] S705: When the heating module 304 continues to heat, the temperature sensor 302 continues to collect temperature values, and the humidity sensor 301 continues to collect humidity values. When the temperature value is greater than a preset temperature value, and / or the humidity value is less than a preset humidity value, the first controller 310 generates a control signal for a stop heating instruction. After receiving the control signal, the heating controller controls the heating module 304 to be in a stop heating state, to prevent overheating from damaging the heating device.

[0097] The specific implementation of each flow step has been described in detail above, and will not be repeated here. In addition, it should be understood that, for the above method embodiments, in order to simply describe, they are all expressed as a combination of a series of actions, but those skilled in the art should know that the disclosure is not limited by the action sequence described above. Secondly, those skilled in the art should know that the above-described embodiments belong to preferred embodiments, and the steps involved are not necessarily required by the disclosure.

[0098] Through the above technical solution, the medium is filled in the sealed space formed by the lens 305 and the light-transmitting lens 303 of the camera device, and the lens 305 and / or the light-transmitting lens 303 in the camera device is defogged by heating the medium by the heating module 304. Compared with the way of directly heating the lens 305 or the light-transmitting lens 303 to defog in the related art, the lens 305 and / or the light-transmitting lens 303 can be avoided to be directly heated, so that the damage of the lens 305 and / or the light-transmitting lens 303 can be reduced, the defogging efficiency can be improved, and the lens 305 and / or the light-transmitting lens 303 can be prevented from being scratched. At the same time, the heating of the heating module 304 is controlled by comparing the temperature value with the preset temperature value and comparing the humidity value with the preset humidity value, so that the sensitivity and accuracy of the heating module 304 to remove the fog on the lens 305 and / or the light-transmitting lens 303 can be improved.
