The driver can accurately grasp the reversing operation through the image.

[0004] However, in extreme weather or extreme road conditions, the lens of the reversing camera is easily blocked by dust and other foreign matters. Since the driver usually does not pay attention to the reversing camera, if the lens is blocked, the driver can only discover it when observing the image in the vehicle display and clean the lens by himself, resulting in poor user experience.

[0037] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0038] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure pertains.

The terms “upper,” “lower,” “left,” “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0039] Nowadays, most vehicles are equipped with a rearview camera, which, combined with an in-car infotainment system, forms a reversing camera system. The camera captures images of the environment behind the vehicle, which are then displayed on the infotainment system. This allows the driver to accurately control the reversing maneuver. However, in extreme weather or road conditions, such as during sandstorms or when driving through muddy areas, the reversing camera can easily become obstructed by dust or other debris. Typically, drivers don't notice if the camera is obstructed, meaning they only discover this during reversing by viewing the image on the infotainment system and then manually remove the camera to clean it, resulting in a poor user experience.

[0040] This disclosure provides a vehicle reversing camera cleaning system, such as... Figure 1 As shown, the vehicle reversing camera cleaning system includes a reversing camera 1, a control component 2, and a cleaner 3.

[0041] The control component 2 is electrically connected to the cleaner 3 and is used to determine whether the lens 101 of the reversing camera 1 is blocked by a foreign object. If the lens 101 is blocked by a foreign object, the cleaner 3 is controlled to emit water towards the lens 101.

[0042] In this way, the control component 2 can control the cleaner 3 to spray water onto the lens 101 when the lens 101 is blocked by foreign objects, so as to clean the foreign objects blocking the lens 101, ensuring that the reversing camera is not blocked when the driver is reversing, avoiding the need for the driver to get out of the car to wipe the lens, thereby improving the user experience.

[0043] It is understandable that the cleaner 3 can be a vehicle water sprayer, whose internal structure and composition are basically the same as those of the vehicle water sprayer located on the windshield of the vehicle, except that the setting position of the vehicle water sprayer on the windshield of the vehicle is different.

[0044] In some possible embodiments, the control component 2 determines whether the lens 101 is obstructed by smoothness detection.

[0045] In one example, control component 2 includes a transmitter 21, a receiver 22, and a controller 23. For example... Figure 2 As shown, transmitter 21 and receiver 22 are electrically connected to controller 23. Transmitter 21 is used to emit an infrared beam to lens 101. Receiver 22 is located on the reflected light path of the infrared beam and is used to receive the infrared light reflected by lens 101 and send the light intensity value of the infrared light to controller 23. Controller 23 is electrically connected to cleaner 3 and is used to determine the magnitude of the light intensity value and a first light intensity threshold. If the light intensity value is less than the first light intensity threshold, controller 23 controls cleaner 3 to emit water flow to lens 101.

[0046] The transmitter 21 can be located on the first side of the reversing camera 1, and the receiver 22 can be located on the second side of the reversing camera. The angle between the light outlet of the transmitter 21 and the lens 101 is equal to the angle between the lens 101 and the light inlet of the receiver 22. In this way, it can be ensured that the infrared beam emitted by the transmitter 21 is reflected into the receiver 22 as much as possible after being reflected by the lens 101.

[0047] In one example, after receiving infrared light reflected from lens 101, receiver 22 determines the intensity value of the infrared light and sends it to controller 23. Controller 23 has a first intensity threshold pre-stored. Controller 23 compares the intensity value sent by receiver 22 with the first intensity threshold to determine the magnitude of the difference. If the intensity value is less than the first intensity threshold, it indicates that at least part of the infrared light emitted by transmitter 21 is converted from specular reflection to diffuse reflection after passing through lens 101, preventing it from entering receiver 22. Therefore, controller 23 determines that lens 101 is at least partially blocked by a foreign object. Subsequently, controller 23 controls cleaner 3 to spray water onto lens 101 to clean the foreign object obstructing the surface of lens 101.

[0048] In an example, the controller 23 also pre-stores a second light intensity threshold, which is smaller than the first light intensity threshold. The controller 23 can determine whether the posture of the emitter 21 and the receiver 22 relative to the lens 101 is normal by comparing the light intensity value with the second light intensity threshold.

[0049] Specifically, the second light intensity threshold can be a very small preset value. The specific sizes of the second light intensity threshold and the first light intensity threshold can be set by the technician according to actual needs, and the embodiments of the present disclosure do not limit this.

[0050] In implementation, after the controller 23 obtains the light intensity value from the receiver 22, the controller 23 compares the light intensity value sent by the receiver 22 with the first light intensity threshold and the second light intensity threshold respectively, and determines the size of the light intensity value and the first light intensity threshold and the second light intensity threshold. If the light intensity value is smaller than the second light intensity threshold, at this time the receiver 22 cannot receive infrared light or can only receive a very small part of the infrared light, which indicates that the posture of the emitter 21 and the receiver 22 relative to the lens 101 is abnormal. If the light intensity value is greater than or equal to the second light intensity threshold and smaller than the first light intensity threshold, at this time the posture of the emitter 21 and the receiver 22 relative to the lens 101 is normal, but at least part of the infrared light emitted by the emitter 21 is converted from specular reflection to diffuse reflection after passing through the lens 101, resulting in the inability to enter the receiver 22. Thus, the controller 23 determines that the lens 101 is at least partially blocked by foreign matter, and then the controller 23 controls the cleaner 3 to emit water flow to the lens 101 to clean the foreign matter blocking the surface of the lens 101. If the light intensity value is greater than or equal to the first light intensity threshold, the posture of the emitter 21 and the receiver 22 relative to the lens 101 is normal, and the lens 101 is not blocked by foreign matter.

[0051] In an example, the reversing camera cleaning system further comprises a car display 4, which is electrically connected with the controller 23. The controller 23 is further configured to display a light path abnormality prompt on the car display 4 when the light intensity value is smaller than the second light intensity threshold.

[0052] Referring to Figure 3 , the controller 23 compares the light intensity value sent by the receiver 22 with the second light intensity threshold, and determines the size of the light intensity value and the second light intensity threshold. If the light intensity value is smaller than the second light intensity threshold, the controller 23 displays a light path abnormality prompt on the car display 4. The light path abnormality prompt can be displayed on the car display 4 in the form of a pop-up window. Specifically, the pop-up window can have the text information “Tip! Light path abnormality!” in the middle of the window. The pop-up window is used to inform the driver that the posture of the emitter 21 and the receiver 22 relative to the lens 101 is abnormal, and to remind the driver to adjust the posture of the emitter 21 and the receiver 22 relative to the lens 101.

[0053] In an example, the reversing camera 1, the transmitter 21, the receiver 22 and the controller 23 in the control assembly 2, and the cleaner 3 are respectively electrically connected with a 12-volt direct current battery in the vehicle, which is used to provide power for the reversing camera 1, the control assembly 2 and the controller 23.

[0054] In this way, for the hybrid vehicle, the power required by the reversing camera cleaning system and the power required by the vehicle driving can be respectively provided by the 12-volt direct current battery and the power battery, so as to reduce the difficulty of power management of the vehicle.

[0055] In some possible embodiments, the control assembly 2 is electrically connected with the reversing camera 1, the control assembly 2 acquires the image captured by the reversing camera 1, and determines whether the lens 101 is blocked by analyzing the image.

[0056] In an example, the control assembly 2 is configured to acquire the rear view image of the vehicle captured by the reversing camera 1, input the rear view image of the vehicle into the foreign matter blocking judgment model to obtain a foreign matter blocking judgment result, and control the cleaner 3 to emit water flow to the lens 101 in a case where the foreign matter blocking judgment result is blocking.

[0057] The foreign matter blocking judgment model has been trained, and the training process of the foreign matter blocking judgment model is described as follows. The process includes:

[0058] 501. Acquire a plurality of sample rear view images in a sample rear view video of a vehicle.

[0059] The sample rear view video refers to a video recorded by a rear view camera of the vehicle. The sample rear view image can be an image of any frame in the rear view video.

[0060] In implementation, after all the sample rear view images in the sample rear view video are obtained, the sample rear view images can be sequentially arranged in time sequence.

[0061] 502. Screen the sample rear view images to obtain target sample rear view images.

[0062] In implementation, the sample rear view images meeting the foreign matter blocking condition in the sample rear view images can be determined as the target sample rear view images by manual screening, and the target sample rear view images are used to input the foreign matter blocking judgment model which has not been trained.

[0063] 503. Train and parameterize the foreign matter blocking judgment model with the target sample rear view images to obtain the foreign matter blocking judgment model after parameterization.

[0064] In implementation, the technician can first determine the target sample vehicle rear view image and the shield as input sample data, and first label the correct shield result for the input target sample vehicle rear view image. Then, the input sample data is input into the foreign matter shield judgment model to be trained to obtain a predicted foreign matter shield judgment result. Then, the predicted foreign matter shield judgment result and the benchmark foreign matter shield judgment result can be input into a preset loss function to calculate a corresponding loss value. Further, based on the loss value, an adjustment value corresponding to each to-be-adjusted parameter in the foreign matter shield judgment model to be trained is calculated, and the corresponding to-be-adjusted parameter is adjusted based on the adjustment value to obtain the foreign matter shield judgment model after adjustment.

[0065] 504、If the training adjustment meets the preset end condition, the foreign matter shield judgment model after adjustment is determined as the trained foreign matter shield judgment model.

[0066] In implementation, the technician can train and adjust the foreign matter shield judgment model to be trained based on the calculated loss value, so that the foreign matter shield judgment result output by the foreign matter shield judgment model to be trained is more accurate, thereby obtaining an output accurate foreign matter shield judgment model. The foreign matter shield judgment model to be trained is trained multiple times until the preset end condition is reached, and then the training is stopped. The preset end condition can be various, and the following gives several conditions that meet the preset end condition:

[0067] (1) The loss value in the continuous preset number of times of training is less than the preset loss value threshold.

[0068] The preset number and the preset loss value threshold can be any reasonable value, for example, the preset number can be 50 or 100, and the present embodiment is not limited in this regard. In implementation, the foreign matter shield judgment model in training gradually reduces the loss value between the predicted foreign matter shield judgment result output by the model and the benchmark foreign matter shield judgment result in the overall trend through parameter adjustment. If after a certain number of training (such as 10000 times of training), the loss value in the continuous preset number of times of training is less than the preset loss value threshold, then the current model can be considered as a trained foreign matter shield judgment model.

[0069] (2) In the continuous preset number of times of training, the model judgment accuracy exceeds the preset accuracy threshold.

[0070] The preset number and the preset accuracy threshold can be any reasonable value, for example, the preset number can be 50 or 100, and the preset accuracy threshold can be 90%, etc., and the present embodiment is not limited in this regard.

[0071] In implementation, the foreign matter occlusion judgment model in training gradually increases the judgment accuracy of the model in the overall trend through parameter adjustment. If the model judgment accuracy exceeds the preset accuracy threshold in continuous preset number of times of training after a certain number of times of training (such as 1000 times of training), it can be considered that the current model is a trained foreign matter occlusion judgment model.

[0072] In an example, the reversing camera cleaning system further comprises a car display 4, and the car display 4 is electrically connected with the control component 2.

[0073] In implementation, the control component 2 is configured to acquire a rear view image of the vehicle captured by the reversing camera 1, input the rear view image of the vehicle into the foreign matter occlusion judgment model to obtain a foreign matter occlusion judgment result, display the rear view image of the vehicle and a cleaning trigger control on the car display 4 in the case that the foreign matter occlusion judgment result is occlusion, and control the cleaner 3 to emit water flow to the lens 101 in response to detecting a click operation of the cleaning trigger control.

[0074] Referring to Figure 4 , the control component 2 can display the rear view image of the vehicle and the cleaning trigger control on the car display 4 in the form of a pop-up window. Specifically, the left side of the car display 4 can display the cleaning trigger control, and the right side of the car display 4 can display the rear view image of the vehicle. The control component 2 is configured to control the cleaner 3 to emit water flow to the lens 101 in response to detecting a click operation of the cleaning trigger control.

[0075] Optionally, the control component 2 can also be configured to control the rear view image of the vehicle to fill the entire display area of the car display 4 in response to detecting a click operation of the rear view image of the vehicle.

[0076] In actual driving process, there may be a situation that the driver needs to immediately perform a reversing operation. At this time, the reversing camera may be occluded by foreign matter, but the occlusion range is small or does not affect the reversing operation to be performed by the driver. At this time, the control component 2 can display the rear view image of the vehicle and the cleaning trigger control on the car display 4 at the same time, so that the driver can judge whether the foreign matter occlusion range affects the current reversing operation according to the current rear view image of the vehicle. If the foreign matter occlusion range does not affect the current reversing operation, the driver can grasp the reversing operation according to the current rear view image of the vehicle. If the foreign matter occlusion range indeed affects the current reversing operation, the driver can trigger the control component 2 to control the cleaner 3 to emit water flow to the lens 101 by clicking the cleaning trigger control, so as to clean the foreign matter and then perform the reversing operation, thereby improving the operation flexibility.

[0077] In some possible embodiments, the control component 2 determines whether the lens 101 is occluded by foreign matter according to a preset period. The preset period can be 1 minute, 2 minutes or 5 minutes.

[0078] In an example, the control assembly 2 comprises a transmitter 21, a receiver 22 and a controller 23. The transmitter 21 is configured to emit an infrared light beam to the lens 101. The receiver 22 is electrically connected to the controller 23. The receiver 22 is located on the reflected light path of the infrared light beam. The receiver 22 is configured to receive the infrared light reflected by the lens 101 and send the light intensity value of the infrared light to the controller 23. The controller 23 is electrically connected to the cleaner 3. The controller 23 is configured to determine the size of the light intensity value and the first light intensity threshold value. In the case that the light intensity value is less than the first light intensity threshold value, the controller 23 is configured to obtain the rear view image of the vehicle captured by the reversing camera 1, input the rear view image of the vehicle into the foreign matter blocking judgment model to obtain a foreign matter blocking judgment result, and control the cleaner 3 to emit water flow to the lens 101 in the case that the foreign matter blocking judgment result is blocking.

[0079] Optionally, the reversing camera cleaning system further comprises a vehicle machine display 4. The controller 23 is electrically connected to the vehicle machine display 4. In this example, the controller 23 is further configured to input the rear view image of the vehicle into the foreign matter blocking judgment model to obtain a foreign matter blocking judgment result, and display the light path abnormality prompt on the vehicle machine display 4 in the case that the foreign matter blocking judgment result is unblocking.

[0080] In this way, the accuracy of determining whether the lens 101 is blocked by foreign matter can be improved.

[0081] The specific steps of controlling the cleaner 3 to emit water flow to the lens 101 and displaying the light path abnormality prompt on the vehicle machine display 4 can be referred to the description above, which will not be repeated here.

[0082] In some possible embodiments, the control assembly 2 is further configured to estimate a target starting time based on the starting times in a preset historical time period, determine a target cleaning time based on the target starting time and a reserved time period, and control the cleaner 3 to emit water flow to the lens 101 at the target cleaning time.

[0083] The preset historical time period can be three days or one week. The reserved time period can be 10 minutes or 15 minutes. The historical time period and the reserved time period can be set by the technician according to actual needs, which are not limited in the embodiments of the present disclosure.

[0084] In implementation, the control assembly 2 is electrically connected to the vehicle machine system of the vehicle. When the vehicle is started, the control assembly 2 can record the starting time of the vehicle. The target starting time can be estimated based on the starting times in a plurality of preset historical time periods. The steps of estimating the target starting time can be as follows:

[0085] (1) Determine the time segment to which the recorded starting time of the vehicle belongs.

[0086] In implementation, a plurality of time segments are pre-stored in the control component 2. The number of time segments can be 3-6, for example, 3 time segments are pre-stored in the control component 2, each time segment corresponds to a time span of 8 hours, the 3 time segments are respectively the first time segment 6:01-14:00, the second time segment 14:01-22:00, and the third time segment 22:01-6:00 of the next day, each time the vehicle is started, the control component 2 determines the time segment to which the current starting time belongs based on the current starting time, for example, the current starting time is 8:15, and the current starting time belongs to the first time segment by determining the end value of the time segment.

[0087] (2) Determine the average starting time of the time segment corresponding to the current starting time within the preset historical time length.

[0088] In implementation, the current starting time can be 8:19, the control component 2 determines that the current starting time belongs to the first time segment, then determines the average starting time corresponding to the historical starting time in the first time segment within the preset historical time length, for example, the historical starting time of the first time segment in the past three days is 8:10, 8:15 and 8:20, and the average starting time can be determined as 8:15.

[0089] (3) Determine the above average starting time as the target starting time.

[0090] In implementation, after determining the target starting time, the time point located before the target starting time and separated from the target starting time by the reserved time length can be determined as the target cleaning time point based on the target starting time, and the control component 2 can control the cleaner 3 to clean the lens 101 at the target cleaning time point. Thus, it is ensured that the lens 101 of the reversing camera 1 is not blocked by foreign matter when the driver starts the vehicle near the target starting time.

[0091] In an example, for any working day, the control component 2 can estimate the second starting time in the working day based on the first stopping time in the working day and the preset working time length, and determine the target cleaning time point based on the second starting time and the reserved time length.

[0092] Wherein, the first stopping time is the time when the vehicle is turned off for the first time in the first time segment or the second time segment. The preset working time length can be 9.5 hours.

[0093] Currently, the flexible working system is gradually popularized. The flexible working system is a working system in which only the working time in an arbitrary working day is ensured to be unchanged, and the off-work time changes according to the change of the work time. For example, if an employee starts work at 8:30, the off-work time can be 18:00, if an employee starts work at 9:30, the off-work time can be 19:00, and if an employee starts work at an arbitrary time within 8:30-9:30, the off-work time is the time corresponding to 9.5 hours after the work time.

[0094] In implementation, when the vehicle is parked with the engine off in the first time segment or the second time segment, the control component 2 can determine the time of parking with the engine off as the first stop time, then determine the time located after the first stop time and away from the first stop time by a preset working time as the second start time, and determine the time located before the second start time and away from the second start time by a reserved time as the target cleaning time.

[0095] For example, in the case where the preset working time is 9.5 hours and the reserved time is 10 minutes, the vehicle is parked with the engine off at 9:20. The control component 2 can determine 9:20 as the first stop time, then determine 18:50 as the second start time, and determine 18:40 as the target cleaning time.

[0096] The technical scheme provided by the embodiment of the present disclosure at least has the following beneficial effects:

[0097] The embodiment of the present disclosure provides a vehicle reversing camera cleaning system, wherein a control component 2 for determining whether the lens of the reversing camera is blocked by foreign matter is arranged in the vehicle reversing camera cleaning system, and the control component 2 can control the cleaner 3 to emit water flow to the lens 101 to clean the foreign matter blocking the lens 101 in the case where the lens 101 is blocked by foreign matter, so that the driver can ensure that the reversing camera is not blocked when performing the reversing operation, and the driver can avoid wiping the lens by himself, thereby improving the user experience.

[0098] The embodiment of the present disclosure provides a vehicle, which comprises the vehicle reversing camera cleaning system described above.

[0099] The above description is only optional embodiments of the present disclosure, and does not limit the present disclosure.
