Description

Technical Field

[0001] The present application relates to the field of intelligent vehicle control technology, and in particular to a method and system for defogging a front cover of a vehicle-mounted camera. Background Art

[0002] Due to the rapid development of the automotive industry, autonomous driving technology has become more mature, and more and more autonomous driving assistance functions have been applied to the automotive field. The controllers or sensors that implement these functions are distributed in various places in the car. If one of the components is affected by the environment, it is very likely that the controller or sensor at that location will have problems, which will affect the use of the autonomous driving function, and more seriously, may cause an accident.

[0003] Since the vehicle's assisted driving relies on vehicle cameras, some cameras are installed on the cover behind the vehicle's interior rearview mirror. Therefore, when there is water mist on the cover in front of the camera and the camera is blocked, the safe operation of the vehicle's assisted driving is affected.

[0004] In the related art, when the assisted driving mode is turned on, there is no judgment on whether there is water mist on the cover. When water mist exists on the cover, the assisted driving is turned on, which affects the safe operation of the assisted driving. In addition, there is currently a method of adding heating wires to the windshield of the vehicle, and defogging the cover and windshield inside the vehicle by heating with the heating wires or heating with the air conditioner in the vehicle. However, the heating wires are used to heat the entire glass when there is water mist, and because the heating range is large, the defogging time is very long. The water mist on the cover cannot be completely removed in a short period of time, and it is not easy for the air conditioner to blow into this cover area. At the same time, it takes a long time to dispel the water mist in this area by the air conditioner alone, which affects the safe operation of the assisted driving. Summary of the invention

[0035] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0036] Before explaining the method for defogging a front cover of a vehicle-mounted camera proposed in the present application, the application scenario of the method for defogging a front cover of a vehicle-mounted camera proposed in the present application is first introduced.

[0037] The present application proposes a method for defogging a front cover of a vehicle-mounted camera, which is applied when a vehicle auxiliary driving function is turned on and when the vehicle is driving.

[0038] Due to the rapid development of the automotive industry, autonomous driving technology has become more mature, and more and more autonomous driving assistance functions have been applied to the automotive field. The controllers or sensors that implement these functions are distributed in various places in the car. If one of the components is affected by the environment, it is very likely that the controller or sensor at that location will have problems, which will affect the use of the autonomous driving function, and more seriously, may cause an accident.

[0039] Since the vehicle's assisted driving relies on vehicle cameras, some cameras are installed on the cover behind the vehicle's interior rearview mirror. Therefore, when there is water mist on the cover in front of the camera and the camera is blocked, the safe operation of the vehicle's assisted driving is affected.

[0040] In the related art, when the assisted driving mode is turned on, there is no judgment on whether there is water mist on the cover. When water mist exists on the cover, the assisted driving is turned on, which affects the safe operation of the assisted driving. In addition, there is currently a method of adding heating wires to the windshield of the vehicle, and defogging the cover and windshield inside the vehicle by heating with the heating wires or heating with the air conditioner in the vehicle. However, the heating wires are used to heat the entire glass when there is water mist, and because the heating range is large, the defogging time is very long. The water mist on the cover cannot be completely removed in a short period of time, and it is not easy for the air conditioner to blow into this cover area. At the same time, it takes a long time to dispel the water mist in this area by the air conditioner alone, which affects the safe operation of the assisted driving.

[0041] The present application provides a method for defogging a front cover of a vehicle-mounted camera, which is applied to a vehicle with an assisted driving function, the vehicle comprising: an image acquisition unit, a heating module, an image recognition unit, a temperature difference sensor and a control unit;

[0042] A heating module, used for heating the front cover of the vehicle-mounted camera;

[0043] An image acquisition unit, used to acquire an image of a front cover of the vehicle camera after receiving an auxiliary driving start instruction;

[0044] An image recognition unit is used to recognize the image of the front cover of the vehicle-mounted camera and determine whether there is water mist on the front cover of the vehicle-mounted camera;

[0045] Temperature difference sensor, used to obtain the temperature difference between inside and outside of the vehicle;

[0046] The control unit is used for controlling the heating module to heat the front cover of the vehicle camera when it is determined that there is water mist on the front cover of the vehicle camera, until there is no water mist on the front cover of the vehicle camera, and controlling the assisted driving function to be turned on; after the vehicle turns on the assisted driving function, when the temperature difference between the inside and outside of the vehicle is greater than or equal to the temperature difference critical value, controlling the heating module to heat the front cover of the vehicle camera until the temperature difference between the inside and outside of the vehicle is less than the temperature difference critical value.

[0047] Those skilled in the art should understand that the above-mentioned application scenarios and modules in the vehicle are only examples, and other existing or future application scenarios and modules, if applicable to the embodiments of the present application, should also be included in the protection scope of the embodiments of the present application and are included here by reference.

[0048] It should be noted that the business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0049] Next, a method for defogging the front cover of a vehicle-mounted camera provided in the present application is explained in detail. Figure 1 This is a flow chart of a vehicle camera front cover defogging method for activating assisted driving provided by the present application. Figure 2 This is a flow chart of a method for defogging a front cover of a vehicle camera provided by the present application to determine whether to heat and defog the cover; Figure 1 , Figure 2 The present application provides a method for defogging a front cover of a vehicle-mounted camera, comprising the following steps.

[0050] After receiving the instruction to start the assisted driving, an image of the front cover of the vehicle camera is obtained;

[0051] Recognize the image of the front cover of the vehicle camera to determine whether there is water mist on the front cover of the vehicle camera;

[0052] When it is determined that there is no water mist on the front cover of the vehicle-mounted camera, the auxiliary driving function is controlled to be turned on;

[0053] When it is determined that there is water mist on the front cover of the vehicle-mounted camera, the front cover of the vehicle-mounted camera is heated until there is no water mist on the front cover of the vehicle-mounted camera, and the auxiliary driving function is controlled to be turned on.

[0054] Therefore, the present application provides a method for defogging the front cover of a vehicle camera. After receiving the assisted driving start command, it is first determined whether there is water mist on the front cover of the vehicle camera. When it is determined that there is water mist on the front cover of the vehicle camera, the front cover of the vehicle camera is heated until there is no water mist on the front cover of the vehicle camera. The assisted driving function is then controlled to be turned on, thereby ensuring the safe operation of the vehicle after the assisted driving function is started.

[0055] Regardless of whether the assisted driving function is turned on when the vehicle is stationary or in driving, the present application first determines whether there is water mist on the cover in front of the vehicle camera after obtaining the assisted driving start instruction. Only when there is no water mist on the cover in front of the vehicle camera, the assisted driving function is directly controlled to be turned on; when it is determined that there is water mist, the cover in front of the vehicle camera needs to be heated to remove the water mist. Only when the water mist on the cover in front of the vehicle camera is completely removed, the assisted driving function will be controlled to be turned on.

[0056] In order to improve the efficiency of removing water mist from the front cover of the vehicle camera, the present application stipulates that when it is determined that there is water mist on the front cover of the vehicle camera, the proportion of the water mist area in the image of the front cover of the vehicle camera is also determined. When the proportion is less than a proportion threshold, the front cover of the vehicle camera is heated at low power; when the proportion is greater than or equal to the proportion threshold, the front cover of the vehicle camera is heated at high power.

[0057] Specifically, an image recognition unit is used to determine whether there is water mist on the front cover of the vehicle camera, and to determine the proportion of the water mist area in the image of the front cover of the vehicle camera, and different status signals 1x are output according to different proportions, where x is 0 or 1; when the image recognition unit determines that there is water mist on the front cover of the vehicle camera, and the proportion of the water mist area in the image of the front cover of the vehicle camera is less than a proportion threshold, the output status signal is 10, and the control unit controls the heating module to perform low-power heating on the front cover of the vehicle camera in the first gear according to the signal to remove the water mist; when the image recognition unit determines that there is water mist on the front cover of the vehicle camera, and the proportion of the water mist area in the image of the front cover of the vehicle camera is greater than or equal to the proportion threshold, the output status signal is 11, and the control unit controls the heating module to perform high-power heating on the front cover of the vehicle camera in the second gear according to the signal to remove the water mist.

[0058] The image recognition unit constantly acquires the image of the cover in front of the vehicle camera, so it can immediately determine whether the water mist on the cover in front of the vehicle camera is completely removed. When it is determined that the water mist on the cover in front of the vehicle camera is completely removed, it outputs a status signal 00, and the control unit controls the heating module to stop working based on the signal, thereby stopping the heating of the cover in front of the vehicle camera, and at the same time controls the assisted driving function to be turned on.

[0059] Preferably, the percentage threshold is 1 / 2.

[0060] Since the temperature of the vehicle changes continuously due to weather or rain and snow during driving, water mist will gradually form on the cover in front of the vehicle camera. In order to prevent the formation of water mist on the cover in front of the vehicle camera from affecting the auxiliary driving function, this application also obtains the temperature difference between the inside and outside of the vehicle after the vehicle turns on the auxiliary driving function;

[0061] When the temperature difference between the inside and outside of the vehicle is greater than or equal to the critical temperature difference value, the cover in front of the vehicle camera is heated until the temperature difference between the inside and outside of the vehicle is less than the critical temperature difference value.

[0062] After the assisted driving function is turned on, the temperature difference between the inside and outside of the vehicle is monitored, and then whether the heating module heats the cover in front of the vehicle camera is controlled. This can effectively prevent the appearance of water mist on the cover in front of the vehicle camera, thereby ensuring the safe operation of the vehicle after the assisted driving function is started.

[0063] The present application also stipulates that when the temperature difference between the inside and outside of the vehicle is greater than or equal to the temperature difference critical value, the error between the temperature difference between the inside and outside of the vehicle and the temperature difference critical value is also calculated; when the error is less than the set temperature error threshold, the front cover of the vehicle camera is heated at low power; when the error is greater than or equal to the set temperature error threshold, the front cover of the vehicle camera is heated at high power.

[0064] Specifically, a temperature difference sensor is used to obtain the temperature difference between the inside and outside of the vehicle. When the temperature difference between the inside and outside of the vehicle is greater than or equal to the temperature difference critical value, the error between the temperature difference between the inside and outside of the vehicle and the temperature difference critical value is also calculated; when the error is less than the set temperature error threshold, the output state signal is 10, and the control unit controls the heating module to perform low-power heating on the front cover of the vehicle camera in the first gear according to the signal to remove water mist; when the error is greater than or equal to the set temperature error threshold, the output state signal is 11, and the control unit controls the heating module to perform high-power heating on the front cover of the vehicle camera in the second gear according to the signal to remove water mist.

[0065] The temperature difference sensor constantly obtains the temperature difference between the inside and outside of the vehicle, so it can immediately determine whether the water mist on the front cover of the vehicle camera has been completely removed. When it is determined that the water mist on the front cover of the vehicle camera has been completely removed, it outputs a status signal 00, and the control unit controls the heating module to stop working based on the signal, thereby stopping the heating of the front cover of the vehicle camera.

[0066] The above two heating methods are not independent, but related to each other, that is, when the temperature difference between the inside and outside of the vehicle is greater than or equal to the temperature difference critical value, or when it is determined that there is water mist on the cover in front of the vehicle camera based on the image of the cover in front of the vehicle camera, the heating module is controlled to heat the cover in front of the vehicle camera. Only when the temperature difference between the inside and outside of the vehicle is less than the temperature difference critical value, and it is determined that there is no water mist on the cover in front of the vehicle camera based on the image of the cover in front of the vehicle camera, the heating function of the heating module on the cover in front of the vehicle camera will be turned off.

[0067] Preferably, the temperature error threshold is set to 5°C.

[0068] The low power is 10W and the high power is 20W.

[0069] To summarize, the present application provides a method for defogging the front cover of a vehicle camera. Before the assisted driving function is turned on, it is first determined whether there is water mist on the front cover of the vehicle camera. When it is determined that there is water mist on the front cover of the vehicle camera, the front cover of the vehicle camera is heated until there is no water mist on the front cover of the vehicle camera. Only then is the assisted driving function controlled to be turned on. When the assisted driving function is turned on, the front cover of the vehicle camera is heated in a timely manner according to the temperature difference between the inside and outside of the vehicle to prevent the formation of water mist on the front cover of the vehicle camera, thereby ensuring the safe operation of the vehicle after the assisted driving function is turned on.
