[0002] With the development of the automobile industry, consumers have increasingly higher requirements for the cleanliness and high-end appearance of vehicles. However, in actual driving, pollutants are often splashed onto vehicles. These pollutants may be mud on rainy roads or sand in dusty weather. Pollutants attached to vehicles not only affect the appearance of the vehicle, but may also cause damage to the vehicle. For example, mud splashes may adhere to the surface of the bumper through the gap between the bumper and the fender. If it is not cleaned in time, it will not only affect the appearance of the vehicle, but also damage the protective layer on the surface of the bumper, accelerate the damage of the bumper, and reduce the expected life of the bumper.

[0003] To address the problem of pollutants adhering to vehicle surfaces, existing automobile manufacturers generally improve vehicle coatings in the hope that pollutants are difficult to adhere to the vehicle surface, or improve vehicle structural design in the hope that pollutants cannot adhere to key protection areas on the vehicle surface. However, none of them have proposed specific methods for effectively testing the effectiveness of vehicle protection tests. Generally, the protection results of specific vehicle designs are evaluated only through subjective evaluation, which is difficult to reflect the actual protection effect and has poor accuracy.

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0028] In a first aspect, an embodiment of the present application provides a vehicle protection testing method.

[0029] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle protection test method of this application. Figure 1 As shown, the vehicle protection test methods include:

[0030] Step S1, after collecting the original characteristic information of the area to be monitored on the vehicle, the vehicle is placed in a variety of preset road conditions, and the driving action of the vehicle is controlled to collect the final characteristic information of the area to be detected on the vehicle after the driving is completed.

[0031] Step S2: combining the original feature information and the final feature information to obtain the coverage area of ​​the monitored area coated by pollutants during driving.

[0032] Step S3: Combine the monitored area and the covered area to obtain a protection effect score, and the covered area is negatively correlated with the protection effect score.

[0033] In this embodiment, original characteristic information of the area to be monitored on the vehicle is collected before the test, the vehicle is placed in a variety of preset road conditions during the test, the vehicle's driving action is controlled, and final characteristic information of the area to be monitored on the vehicle is collected at the end of the test. The original characteristic information and the final characteristic information can be combined to obtain the coverage area of ​​the area to be monitored that is coated with pollutants during driving, and the protection effect score can be obtained by combining the area to be monitored and the coverage area. Through this method, the pollutant coverage area of ​​the vehicle when it is driving in different road conditions and according to different driving actions can be comprehensively and accurately obtained, thereby obtaining an accurate protection effect score.

[0034] Furthermore, in one embodiment, both the original feature information and the final feature information are image data of the area to be monitored.

[0035] In this embodiment, before the vehicle protection test begins, the image acquisition device is used to collect the original image of the area to be monitored on the vehicle, such as the bumper. After the vehicle protection test begins, the vehicle is placed in different preset road conditions. In each road condition, the vehicle is controlled to drive according to the specified driving action. After the vehicle protection test ends, the image acquisition device is used to collect the final image of the area to be monitored on the vehicle, such as the bumper. Combined with the original image of the area to be detected and the final image of the area to be monitored, data analysis is performed to obtain the coverage area of ​​the area to be monitored after driving according to the specified driving action under the specified road condition. The larger the coverage area, the more serious the coating of pollutants. Combined with the coverage area and the area to be monitored, data analysis is performed to obtain the protection effect score of the area to be monitored after driving according to the specified driving action under the specified road condition. The higher the protection effect score, the better the protection effect. Thus, the protection capability of the vehicle after driving according to different driving actions under different road conditions is comprehensively and accurately analyzed. Subsequent automobile companies can optimize the protection design of the vehicle according to the test results, thereby improving the protection effect of the vehicle after it is put on the market and improving the user evaluation.

[0036] Furthermore, in one embodiment, after the vehicle drives according to a set of driving actions in a road condition, a protection effect score is obtained, and then the monitored area of ​​the vehicle is restored to be consistent with the state presented by the original image, and then the vehicle starts to drive again according to a new set of driving actions in a new road condition, and a protection effect score is obtained again. After the vehicle drives according to all preset driving actions in all preset road conditions, all protection effect scores are weighted and summed to obtain a total score that can characterize the protection effect of the vehicle. The weighted weight is related to the road condition environment of the driving area after the vehicle is actually released. For example, the driving area after the vehicle is actually released can be obtained based on historical statistical information. Combined with the historical statistical information, if the actual driving area of ​​the vehicle is mostly rainy, the protection effect score obtained by testing the vehicle in a rainy environment is multiplied by a higher weight, and the protection effect score obtained by testing the vehicle in sandstorm weather is multiplied by a lower weight, so that the protection effect score of the vehicle is more in line with the actual needs of users.

[0037] Furthermore, in one embodiment, both the original feature information and the final feature information are wavelength reflection data of the area to be detected.

[0038] In this embodiment, wavelength reflection technology can detect a variety of information, including but not limited to the surface structure and composition of an object. This technology obtains relevant information about an object by analyzing the reflection characteristics of light, and is applicable to a variety of fields, such as medical diagnosis, material science, etc. In the field of material science, wavelength reflection technology can be used to analyze the surface structure and composition of materials. Different materials have different surface reflection characteristics. By measuring the wavelength and intensity of reflected light, the composition and structural information of the material can be inferred.

[0039] Before the vehicle protection test starts, a signal of a specified wavelength is sent to the area to be monitored on the vehicle through a signal sending device, and then the wavelength reflection signal of the area to be monitored on the vehicle is collected, such as the original wavelength reflection signal of the bumper. After the vehicle protection test starts, the vehicle is placed in different preset road conditions. In each road condition, the vehicle is controlled to drive according to the specified driving action. After the vehicle protection test is completed, a signal of a specified wavelength is sent to the area to be monitored on the vehicle again through the signal sending device, and then the wavelength reflection signal of the area to be monitored on the vehicle is collected, such as the final wavelength reflection signal of the bumper. Since the wavelength reflection signals when the vehicle surface is not coated with pollutants and when coated with pollutants are different, data analysis is performed in combination with the original wavelength reflection signal of the area to be detected and the final wavelength reflection signal of the area to be monitored, and the coverage area of ​​the area to be monitored that is polluted and coated after driving according to the specified driving action under the specified road conditions is obtained. The larger the coverage area, the more serious the coating with pollutants. Data analysis is performed in combination with the coverage area and the area to be monitored, and the protection effect score of the area to be monitored after driving according to the specified driving action under the specified road conditions is obtained. The higher the protection effect score, the better the protection effect. In this way, the protection capability of the vehicle after driving according to different driving actions under different road conditions is comprehensively and accurately analyzed. Subsequent car companies can optimize the protection design of the vehicle according to the test results, thereby improving the protection effect of the vehicle after it is put on the market and improving user evaluation.

[0040] Furthermore, in one embodiment, the original feature information and the final feature information are combined to obtain the coverage area of ​​the monitored area coated by pollutants during driving, which specifically includes the following steps:

[0041] The original feature information and the final feature information are compared, and the set of position points with different comparison results is taken as the coverage area.

[0042] In this embodiment, when the characteristic information is image data, an image recognition algorithm is used to directly identify the total image area in the original characteristic information and the image area of ​​the pollutant coverage area in the final characteristic information, or the two images are compared, and the location points with different comparison results are the pollutant coverage areas.

[0043] In a specific embodiment, when collecting original feature information, a developer is applied to the monitored area. After the developer is evenly applied, the image acquisition system records it by taking photos. After the test, the system takes photos again to record the mud splashing situation, and analyzes and processes the collected images. By gridding the photos, the proportion of the area washed by water to the entire side of the bumper is calculated, and different steps are set according to the proportion. Combined with the design requirements of the car companies, the mud splashing performance of different competing vehicles can be judged.

[0044] Calculation formula: Mud splashing degree (%) = number of grids in the area washed by rainwater (X) / number of grids in the area coated with developer (Y).

[0045] When the road material is mud, the mud splashing degree (A%), with a weight of a%.

[0046] When the road material is sand: mud splashing degree (B%), weight is b%.

[0047] When the road material is gravel: mud splashing degree (C%), the weight is c%.

[0048] Comprehensive mud splashing degree = mud splashing degree (A%) × a% + mud splashing degree (B%) × b% + mud splashing degree (C%) × c%,

[0049] If the comprehensive mud splash degree of vehicle A is less than 50%, the protection performance is judged to be qualified.

[0050] If the comprehensive mud splash degree of vehicle B is less than 40%, the protection performance is judged to be qualified.

[0051] If the comprehensive mud splash degree of vehicle C is less than 30%, the protection performance is judged to be qualified.

[0052] If the comprehensive mud splash degree of vehicle D is less than 20%, the protective performance is judged to be unqualified.

[0053] The developer is evenly applied on the side of the bumper. The device can ensure that the developer is evenly applied on the side of the bumper to avoid observation errors caused by uneven application, so as to facilitate observation of mud splash protection. The developer has good adhesion and visibility and will not cause damage to the bumper.

[0054] Furthermore, in one embodiment, the road condition environment includes road material and road surface water depth.

[0055] In this embodiment, the road material can be soil, sand, gravel, etc., and the depth of water on the road surface can be set according to the test requirements. For example, under a certain road condition, the specific test environment is set to asphalt road surface, water depth of 4 cm, and length of 200 meters. The vehicle is controlled to drive on the road with different driving operations, and then the protection effect of the vehicle is tested.

[0056] Furthermore, in one embodiment, the road condition environment also includes wind speed and ambient temperature.

[0057] In this embodiment, considering that wind speed and ambient temperature may also affect whether pollutants are easily attached to the vehicle, different wind speeds and ambient temperatures may also be set when testing the protective performance of the vehicle, so as to comprehensively analyze the factors affecting the protective performance of the vehicle.

[0058] Furthermore, in one embodiment, the driving action includes vehicle speed, vehicle acceleration, vehicle direction, and vehicle steering angle.

[0059] In this embodiment, the driving, braking and steering operations of the vehicle at different speeds are simulated. The speed, braking force and steering angle of the vehicle are accurately controlled. The driving of the vehicle at different speeds is accurately controlled to simulate various speed changes in actual road driving. By adjusting the braking force and steering angle, complex driving scenarios such as emergency braking and sharp turns are simulated.

[0060] For example: 50 meters / hour, walk back and forth 20 times, braking deceleration 0.4G, turn left 45 degrees while braking, then return the steering wheel to the center, then turn right 45 degrees, and then stop.

[0061] In summary, the present invention provides a standardized testing method and device that can accurately evaluate the protection performance of a vehicle bumper, such as its ability to protect against splashing mud on muddy roads, thereby providing a basis for vehicle manufacturers to improve their designs.

[0062] In a second aspect, an embodiment of the present application also provides a vehicle protection testing system.

[0063] In one embodiment, referring to Figure 2 , Figure 2 This is a functional module diagram of an embodiment of the vehicle protection test device of the present application. Figure 2 As shown, the vehicle protection test device includes:

[0064] The test control module 1 is used to collect the original feature information of the area to be monitored on the vehicle, place the vehicle in a variety of preset road conditions, and collect the final feature information of the area to be detected on the vehicle after the driving is completed by controlling the vehicle's driving action.

[0065] The data processing module 2 is used to combine the original feature information and the final feature information to obtain the coverage area of ​​the monitored area coated by pollutants during driving. It is also used to combine the monitored area and the coverage area to obtain the protection effect score, and the coverage area is negatively correlated with the protection effect score.

[0066] In this embodiment, original characteristic information of the area to be monitored on the vehicle is collected before the test, the vehicle is placed in a variety of preset road conditions during the test, the vehicle's driving action is controlled, and final characteristic information of the area to be monitored on the vehicle is collected at the end of the test. The original characteristic information and the final characteristic information can be combined to obtain the coverage area of ​​the area to be monitored that is coated with pollutants during driving, and the protection effect score can be obtained by combining the area to be monitored and the coverage area. Through this method, the pollutant coverage area of ​​the vehicle when it is driving in different road conditions and according to different driving actions can be comprehensively and accurately obtained, thereby obtaining an accurate protection effect score.

[0067] Furthermore, in one embodiment, both the original feature information and the final feature information are image data of the area to be monitored.

The larger the coverage area, the more serious the coating of pollutants. Combined with the coverage area and the area to be monitored, data analysis is performed to obtain the protection effect score of the area to be monitored after driving according to the specified driving action under the specified road condition. The higher the protection effect score, the better the protection effect. Thus, the protection capability of the vehicle after driving according to different driving actions under different road conditions is comprehensively and accurately analyzed. Subsequent automobile companies can optimize the protection design of the vehicle according to the test results, thereby improving the protection effect of the vehicle after it is put on the market and improving the user evaluation.

After the vehicle drives according to all preset driving actions in all preset road conditions, all protection effect scores are weighted and summed to obtain a total score that can characterize the protection effect of the vehicle. The weighted weight is related to the road condition environment of the driving area after the vehicle is actually released. For example, the driving area after the vehicle is actually released can be obtained based on historical statistical information.
