Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that the illustrations provided in the following embodiments merely illustrate the basic concept of the present invention by way of illustration, and only the components related to the present invention are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complicated.
The engine oil in the vehicle can be used in lubrication, cooling, sealing and other aspects, so that the normal operation of the engine can be ensured, the service life of the engine can be prolonged, and the performance and reliability of the vehicle can be improved. In the use process of the vehicle, the engine oil can be subjected to sites such as oil aging, oil pollution, low oil quantity, oil product reduction and the like in the operation process of the engine, so that the engine oil needs to be replaced periodically or is replenished in time to protect the engine. According to the background art, the existing method for replacing or supplementing engine oil cannot be applied to a hybrid vehicle model, and a first object of the embodiment of the present invention is to provide an engine oil monitoring method, as shown in fig. 1, and fig. 3 shows a step flowchart of the engine oil monitoring method of the present invention, including:
s101, collecting a current engine oil image of a part to be detected of a vehicle;
in this step, the vehicle may be a fuel-powered vehicle type, a new energy-powered vehicle type, or a hybrid vehicle type. The component to be detected may be a component that requires the use of oil and that requires the periodic replacement of oil, such as components of an engine, transmission, hydraulic system, brake system, power steering system, and the like. The engine oil image can be acquired by equipment with a camera function, such as a camera, an engine oil ruler, or the image acquisition device 1 provided by the invention. In some embodiments, one or more components to be detected may be acquired at the same time, resulting in an oil image of the target component to be detected. The engine oil image can intuitively show the engine oil liquid level, the engine oil color, the engine oil impurities and the like of the engine oil.
S102, comparing the engine oil image with a plurality of image identification samples in an image library, wherein different image identification samples are characterized as different periods of engine oil in a life cycle;
s103, determining the current state of the part to be detected in the life cycle based on at least one image identification sample matched with the engine oil image.
Specifically, with the use process of the engine oil, the quality and the liquid level of the engine oil can change, and different patterns, colors, turbidity and other characteristics are formed on the surface of the engine oil, and the complete use process can be expressed as an unused state (new oil) -an in-use state (oil being deteriorated) -a used state (deteriorated oil). In the use process, the quality of the engine oil is continuously deteriorated, and the time which passes when the engine oil is changed from new oil to deteriorated oil can be used as the service life period of the engine oil. The time for each image identification sample collection is different, and the use degree of the engine oil is different, so that the different time periods of the engine oil in the life cycle are corresponding. For example, the image of the new oil identifies the first time that the sample is collected, the best quality oil, its foremost period in the life cycle, the light deterioration of the oil can be considered, and the longest time that the oil needs to be replaced. The deteriorated oil is at the last period of the life cycle, and it can be considered that the oil has deteriorated and that the oil needs to be replaced in time.
Thus, an image of engine oil can be collected, a plurality of image identification samples are obtained, and stored in advance in the vehicle ECU (Engine Control Unit ). And uploading the engine oil image acquired in real time to a vehicle ECU in the use process, and comparing the engine oil image with a plurality of pre-stored image identification samples to obtain an image identification sample similar to the engine oil image.
In some embodiments, a motor oil image may be compared to an image identification sample for similarity, and the image identification sample that matches the motor oil image may be determined based on the similarity. In some embodiments, the similarity may be compared one by at least one feature of the engine oil color, the engine oil impurity, and the engine oil pattern, resulting in at least one image identification sample with at least one feature being similar. In some embodiments, by comparing the oil color, oil impurity, and oil pattern simultaneously, a well-defined image representation sample of all three features is obtained. And judging the current state of the engine oil through the image representation sample.
In this embodiment, in order to ensure that the engine oil image collected in real time can be matched with a similar or identical image identification sample, an image of each stage may be collected as much as possible during the use of the vehicle, for example, an image identification sample may be collected in each of the first driving range and the second driving range. It is understood that the longer the mileage, the closer the period in which the engine oil is in the life cycle, the closer the time to exchange can be considered.
It will be appreciated that it is desirable to collect an image identification sample for each stage of the vehicle, wherein the method of collection may be the same as the method of collection of the engine oil image.
Specifically, the current state includes at least the oil deterioration condition and the oil level information, and is displayed on the dashboard of the vehicle. The engine oil deterioration condition can be represented by an image identification sample, and the time period of the part to be detected in the life cycle can be obtained by the corresponding image identification sample, so that the user is informed of the time for changing the engine oil and the degree of engine oil deterioration; wherein the engine oil level information can be intuitively embodied through the collected engine oil image.
Therefore, the current state (comprising the oil deterioration condition and the oil liquid level) of the oil of the part to be detected is finally converted by obtaining the determined image identification sample similar to or the same as the oil image, and the current state can inform the user of the date of oil maintenance in advance or timely warn the user that the oil maintenance is needed. Compared with the prior art, for the hybrid vehicle type with irregular engine oil deterioration condition, the invention does not need to regularly change the engine oil according to the driving mileage specified by manufacturers, can intuitively and accurately judge whether the part to be detected needs engine oil maintenance or not according to the real-time engine oil image, and can change or supplement the engine oil in time, thereby avoiding the problems of too early oil change, waste of parking time and maintenance cost, too late oil change, influence on the normal work of the part to be detected and the like.
Referring to fig. 2, a schematic diagram of an exemplary oil monitoring method for outputting an oil status according to the present disclosure is shown.
In yet another embodiment, the image library is acquired by:
s201, acquiring the image identification samples of the to-be-tested component under different driving mileage;
s202, acquiring oil sample quality information corresponding to different driving ranges, wherein the oil sample quality information at least comprises a period corresponding to the engine oil in a life cycle under the corresponding driving ranges;
s203, storing the image identification sample and the corresponding oil sample quality information in the image library in an associated mode.
Specifically, the oil quality information is associated with the image identification sample, so that the oil deterioration condition can be represented by the image identification sample. In some embodiments, images corresponding to engine oil under specific mileage (such as 0Km, 500Km, 1000Km, 1500Km … maintenance mileage and the like) can be collected in a test stage of vehicle development and calibrated as image identification samples, and oil sample quality information. In some embodiments, the quality information of the oil sample can be obtained by laboratory detection on the collected oil sample, and can be generally characterized as parameters such as viscosity, acid value, moisture, density, ph value and the like, wherein the parameters are set with standard values, the standard values can represent the deterioration value of the engine oil, and the closer the detection value of the parameters is to the standard values, the more serious the deterioration degree of the engine oil is considered.
In this embodiment, a set of determined image identification samples and oil sample quality information are corresponding to one set of determined image identification samples and oil sample quality information under the same driving range, and a plurality of sets of calibration image cards are formed, that is, an image library with the image identification samples and the oil sample quality information associated is established, so that each image identification sample can be considered to be calibrated with the oil sample quality information, the oil sample quality information can represent the oil deterioration condition of engine oil, and therefore, the oil deterioration condition of a part to be detected can be obtained by determining the image identification samples corresponding to the oil images. It is understood that the farther the mileage is, the more severe the deterioration of the engine oil is, and the more the period of the engine oil in the life cycle is considered to be. The maintenance mileage may be considered the mileage covered by the engine oil at the last period of the life cycle.
For example, the oil collected at 0Km corresponds to new oil, the difference between the parameter value of the corresponding oil sample quality information and the standard value is large, the period of the oil is the forefront in the life cycle, the oil deterioration condition can be considered light, and the time for replacing the oil is the longest. The oil collected under the maintenance mileage has the corresponding oil sample quality information reaching the deterioration standard and is in the final period of the life cycle, and the oil can be considered to be deteriorated.
Therefore, through establishing the mapping relation between the image identification sample and the oil sample quality information, the oil liquid level and the oil deterioration condition of the part to be detected can be obtained simultaneously through the oil image, the method is wide in applicable vehicle type, high in functional integration level, free of additional acquisition of the current state of the oil through a plurality of modules such as a liquid level sensor and an oil quality sensor, low in cost, and convenient for a user to master more comprehensive oil state information, including oil color, oil definition, oil pollution degree and the like.
In a further technical solution, the oil sample quality information further includes: at least one of an oil failure rate, an oil remaining life time, and an oil remaining maintenance mileage; step S103 may include:
s103-1, acquiring target quality information corresponding to the engine oil image based on the oil sample quality information corresponding to each of at least one image identification sample matched with the engine oil image;
s103-2, determining the current state of the part to be detected in the life cycle based on the target quality information.
In the scheme, the service life cycle of the engine oil of the part to be detected is set in the vehicle ECU, the ECU can analyze and process the time period of the oil sample quality information and the total time of the service life cycle through the data processing module through the corresponding time period of the engine oil under the corresponding driving mileage in the service life cycle, and the results of the determined engine oil inferior rate, the engine oil residual service life duration, the engine oil residual maintenance mileage and the like are converted into the results, and the results are directly fed back to a vehicle instrument panel to be presented to a user. It should be explained that the remaining life time of the engine oil may be the time remaining from the last time of the life cycle; the remaining maintenance mileage of the engine oil can be the remaining driving mileage from the maintenance mileage; the poor quality of the engine oil can be considered as the deterioration degree of the engine oil, and the deterioration degree can be calculated by the detection value and the standard value of the quality information of the oil sample.
The unique and determined target quality information can be obtained through the oil sample quality information, the current state of the part to be detected can be directly and intuitively displayed on the vehicle instrument panel according to parameters such as the oil quality rate, the oil remaining life time, the oil remaining maintenance mileage and the like, a user can grasp the oil state conveniently, countermeasures can be taken in advance, and the need of changing the oil during long-distance running is avoided.
In an implementation, the image library further includes: identifying samples by a plurality of images under different vehicle environments;
step S102, including:
s102-1, acquiring a plurality of target image identification samples in the same vehicle environment as the vehicle;
s102-2, comparing the engine oil image with a plurality of target image identification samples.
Specifically, the environment for using the vehicle can be a region where the vehicle is often driven, and the road conditions or the climate conditions of different regions are different, so that the service life period is different, for example, the service life period of engine oil can be shorter under the conditions of high air temperature, poor road conditions and the like, and the engine oil needs to be replaced more frequently. Therefore, under the same driving mileage, the engine oil liquid level and the engine oil deterioration condition in different vehicle environments are different. For example, when a vehicle travels 100Km, the degree of deterioration of engine oil of a vehicle that is often traveling in a mountain is more serious than that of a vehicle that is often traveling in plain.
In some embodiments, the invention can collect the image identification sample and the oil sample quality information of the test vehicle under different driving mileage under different environments in the test stage of vehicle development, and acquire the image library related to the vehicle environment through steps S201-S203. When the vehicle needs to monitor the engine oil deterioration condition in real time in the use process, a target image identification sample related to the environment where the vehicle is located can be called, for example, when the vehicle is often driven in a mountain region, an obtained engine oil image is compared with an image identification sample in an image library collected in the mountain region by a test vehicle, so that the target image identification sample can more accurately reflect the engine oil deterioration condition of the vehicle, the service life period of engine oil can be more accurately estimated, and the precision and reliability of the image library are improved.
It will be appreciated that the types of in-car environments are numerous and that it is difficult to collect image identification samples that can all include different in-car environments during the trial phase of vehicle development. In some embodiments, through a machine self-learning algorithm, through a model established by an image library, vehicle information (a new image identification sample and new oil sample quality information corresponding to driving mileage under the current vehicle environment) uploaded to a vehicle cloud by a user is combined, more detailed and comprehensive data are collected and analyzed, and a new image library with huge data updated in real time is obtained, so that the use requirements of different users are met, and more high-quality vehicle service is provided for the user.
According to the foregoing, it is necessary to collect current engine oil images of the vehicle and image identification samples of the vehicle under different driving ranges.
