Description

Technical Field

[0001] The present invention relates to the technical field of automotive braking, and particularly to a method, device, electronic device and storage medium for warning of vehicle air pressure leakage. Background Art

[0002] With the development of automotive technology, especially the increasing requirements for braking systems, it has become crucial to detect and warn of vehicle air pressure leakage. In the commercial vehicle industry that uses compressed air as the energy source for the braking system, the air braking system uses an air compressor to provide compressed air, an energy storage device to store compressed air, pipelines for transmission, and various valves or components with different functions to make the compressed air perform the expected functions. Since components such as the energy storage device, pipelines, and valves of the air braking system need to be connected through a large number of connecting joints, there is a possibility of compressed air leakage. For serious leakage, it is easy for the driver to detect, and the sensors on the vehicle will also give an alarm in time; however, for slow leakage, or slow leakage caused by the aging of the air braking system, the sensors cannot judge and identify it, and it is also very difficult for humans to detect. For vehicles using an air braking system, when the vehicle starts, it must ensure that the compressed air reaches a sufficient pressure to ensure sufficient braking ability and safety. When the vehicle has been parked overnight, due to slow leakage, the compressed air pressure is low, and the air compressor needs to slowly inflate to increase the air pressure, which results in a longer start-up time and affects travel efficiency. Slow leakage caused by the aging of the air braking system may suddenly form a violent air leak, resulting in a reduction or loss of the function of the air braking system and endangering driving safety.

[0003] In the prior art, it is usually to collect the air pressure when the vehicle shuts off, the air pressure when the vehicle starts again, and the time, and calculate the difference between the two to determine whether the braking air pressure leaks. However, in actual operation, since the electronic control system will also automatically shut down when the vehicle shuts off, it is very difficult to accurately collect and upload the air pressure when the vehicle shuts off to the system, or the uploaded data may be missed, resulting in inaccurate detection of the vehicle braking air pressure. Summary of the Invention

[0004] In view of this, it is necessary to provide a method, device, electronic device and storage medium for warning of vehicle air pressure leakage to solve the technical problem in the prior art that in the detection method for whether the braking air pressure leaks, more parameters need to be obtained and it is difficult to accurately collect, upload and store offline these parameters.

[0041] The following will specifically describe the preferred embodiments of the present invention with reference to the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, rather than to limit the scope of the present invention.

[0042] A specific embodiment of the present invention discloses a vehicle air pressure leakage warning method. Please refer to Figure 1 , including:

[0043] S101. Obtain the parking duration of the target vehicle and the braking air pressure when the target vehicle starts the engine;

[0044] S102. According to the preset data analysis method, determine the safe air pressure range of the vehicle under different parking durations, and construct a relationship model between the parking duration and the safe air pressure range;

[0045] S103. According to the relationship model between the parking duration and the safe air pressure range, determine the safe air pressure range corresponding to the parking duration of the target vehicle;

[0046] S104. According to the relationship between the braking air pressure when the target vehicle starts the engine and the safe air pressure range, determine the air pressure leakage state of the target vehicle.

[0047] In this embodiment, first, the parking duration of the target vehicle and the braking air pressure when the target vehicle starts the engine are obtained, reducing the collection of vehicle state quantities. Subsequently, according to the preset data analysis method, the safe air pressure range of the vehicle under different parking durations is determined, and a relationship model between the parking duration and the safe air pressure range is constructed. Thus, according to the relationship model, the safe air pressure range corresponding to the parking duration of the target vehicle is determined. Finally, according to the relationship between the braking air pressure when the target vehicle starts the engine and the safe air pressure range, it is judged whether there is leakage in the target vehicle's engine braking. By establishing a relationship model between the parking duration and the safe air pressure range, the present invention can qualitatively obtain whether there is leakage in the vehicle braking and qualitatively analyze the degree of air pressure leakage only by obtaining the parking duration and the braking air pressure when starting the engine. This not only reduces the acquisition of vehicle parameters, but also simplifies the calculation through qualitative analysis of the constructed relationship model, is applicable to any scenario and vehicle, simplifies the calculation, and improves the judgment efficiency of air pressure leakage.

[0048] It should be noted that the preset data analysis method includes using predefined rules, models or algorithms to analyze data. Usually, based on domain knowledge or experience, data is processed through rules and logic, without relying on a large amount of training data and complex model training processes. Specifically, in determining the safe air pressure range of the vehicle, the safe air pressure range under different parking durations is determined through thresholds, without the need for complex machine learning model training and parameter tuning processes, simplifying the calculation of vehicle air pressure leakage warning and improving the calculation efficiency of air pressure leakage.

[0049] Furthermore, since different types of vehicles have different air pressure leakage rates or different starting air pressure values, the relationship model between the parking duration and the safe air pressure range includes various different types of vehicles.

[0050] In some embodiments, for the step of determining the safe air pressure range of the vehicle under different parking durations according to the preset data analysis method, please refer to Figure 2 , including:

[0051] S201. Obtain the historical parking duration data of the vehicle, the braking air pressure when starting the engine, and the historical air pressure leakage information.

[0052] S202. According to the different braking air pressures when starting the engine and the corresponding historical air pressure leakage information under the same parking duration in the historical parking duration data, determine the safe air pressure range corresponding to the parking duration.

[0053] In this embodiment, by collecting and sorting a large amount of historical data, the braking air pressure of the same type of vehicle at the same moment is plotted, and the safe threshold of the braking air pressure is determined according to the air pressure leakage information. When the vehicle air pressure is greater than the safe threshold value, the vehicle is in the normal pressure relief range and no alarm is required. Thus, the safe air pressure range corresponding to the vehicle at this moment is determined. According to this method and steps, the safe air pressure ranges corresponding to the vehicle at all different moments are determined.

[0054] Thus, an integrated real-time monitoring system is integrated. The system can obtain data such as the vehicle braking air pressure and parking duration in real time through sensors and feedback them to the system in a timely manner. In this way, the real-time monitoring of the vehicle state can be realized, and actions can be taken in a timely manner when needed. And monitor the vehicle braking air pressure and parking duration data, and detect abnormal situations in time and trigger early warnings. For example, when the braking air pressure drops abnormally or the air pressure leakage rate increases abnormally, the system can automatically issue an alarm to remind the maintenance personnel to perform maintenance.

[0055] In some embodiments, for the step of determining the safe air pressure range corresponding to the parking duration according to the different braking air pressures when starting the engine and the corresponding historical air pressure leakage information under the same parking duration in the historical parking duration data, please refer to Figure 3 , including:

[0056] S301. According to the historical air pressure leakage information, determine the average value of the braking air pressure when starting the engine when the vehicle engine braking has air pressure leakage under the same parking duration in the historical parking duration data.

[0057] S302. Set a threshold for the braking air pressure to generate leakage according to the average value, and determine the safe air pressure range corresponding to the parking duration.

[0058] In this embodiment, first, calculate the average value of the braking air pressure when starting the vehicle engine under the same parking duration according to the historical data as the reference value. According to the air pressure leakage information, determine the threshold for the braking air pressure to generate leakage, where the threshold is determined according to the average value of the historical leakage air pressure of multiple vehicles at the same moment. Specifically, each vehicle will have air pressure leakage when parking, manifested as the pressure gradually decreasing over time. Combine the average braking air pressure with the set air pressure leakage threshold to determine the safe air pressure range corresponding to the parking duration.

[0059] In some embodiments, determining the safety air pressure range corresponding to the parking duration based on the braking air pressure and the corresponding historical air pressure leakage information at the same parking duration in the historical parking duration data further includes:

[0060] According to the different air pressure drop rates of vehicles with different leakage degrees, respectively determine the average value of the braking air pressure when starting the engine at the same moment for vehicles with different leakage degrees;

[0061] According to the average value of the braking air pressure when starting the engine at the same moment for vehicles with different leakage degrees, determine the correlation between the parking duration and the air pressure leakage degree.

[0062] In this embodiment, by collecting and sorting out a large amount of historical data, the average value of the braking air pressure when starting the engine at the same moment for vehicles with different leakage degrees is determined, and then a relationship model between the parking duration corresponding to the vehicle leakage degree and the braking air pressure is established, so that the leakage degree of the target vehicle can be qualitatively judged through the leakage degree relationship model. If the vehicle is in a slight leakage degree, it can continue to run for a period of time; if the vehicle is in a serious leakage degree, it must be repaired immediately.

[0063] Therefore, through the research on the relationship between the parking duration and the braking air pressure of vehicles with different leakage degrees in this embodiment, the safety and reliability of the vehicle braking system can be improved, potential hazards caused by braking system problems can be reduced, the vehicle maintenance plan can be optimized, the leakage problems of the braking system can be detected and repaired in time, and thus the operation efficiency and safety level of the entire fleet can be improved.

[0064] In a specific embodiment, for vehicles with different leakage degrees, the descending speeds of the curves are different, and the lowest points reached by the descent are different.

[0065] Furthermore, the braking system performance of different types of vehicles or under different driving conditions can also be studied to determine whether there are differences in the braking system performance under specific types of vehicles or driving conditions. Develop customized maintenance strategies and safety policies for specific vehicles or driving situations to further improve the safety and reliability level of the entire fleet. At the same time, it can also be explored how to use advanced sensing technologies and data analysis algorithms to achieve real-time monitoring and predictive maintenance of the braking system to ensure that potential safety problems are detected and solved in time during vehicle operation.

[0066] In some embodiments, the parking duration data of the vehicle includes multiple different types of vehicles; determining the safety air pressure range of the vehicle at different parking durations according to the preset data analysis method further includes:

[0067] Obtain the parking duration data, the braking air pressure when starting the engine, and the historical air pressure leakage information of different types of vehicles;

[0068] Based on the braking air pressure when starting the engine and the corresponding historical air pressure leakage information of the vehicle for the same type of vehicle under the same parking duration, determine the safe air pressure range corresponding to the parking duration of the same type of vehicle.

[0069] In this embodiment, first, obtain the parking duration data, the braking air pressure when starting the engine, and the historical air pressure leakage information of multiple different types of vehicles. These data can be from vehicle monitoring systems, historical records, or other data sources. Classify different types of vehicles, for example, classify them according to vehicle type, manufacturer, or model, etc. Then analyze each category of vehicles. For the same type of vehicle, based on the braking air pressure when starting the engine at different times under the same parking duration and the corresponding air pressure leakage information, determine the safe air pressure range corresponding to the parking duration of this type of vehicle.

[0070] Furthermore, according to the characteristics of different types of vehicles and the data analysis results, it may be necessary to adjust and optimize the setting of the safe air pressure range to ensure its applicability to various vehicles and improve the accuracy and reliability of the prediction.

[0071] In a specific embodiment, the measured values of the braking air pressure of different vehicles at different parking times are shown in Table 1. Among them, Vehicle No. 1 parked for 7 hours, and the braking air pressure dropped to 440, which is lower than the set safety threshold of 517. It is judged that the vehicle has a large braking air pressure leakage, and this vehicle needs to be warned. Among them, Vehicle No. 2 parked for 12 hours, and the braking air pressure dropped to 528, which is higher than the set safety threshold of 492. It is judged that the vehicle has a small braking air pressure leakage and does not need to be warned.

[0073]

[0074] In some embodiments, determining the vehicle air pressure leakage state according to the relationship between the braking air pressure when starting the engine of the target vehicle and the safe air pressure range includes:

[0075] Judge whether the braking air pressure when starting the engine of the target vehicle is within the safe air pressure range;

[0076] If not, it means that the braking of the target vehicle engine has a leakage, and then send a warning.

[0077] In this embodiment, by comparing the relationship between the braking air pressure of the target vehicle engine and the safe air pressure range, it can be qualitatively analyzed whether the vehicle has a leakage, so as to decide whether to send a warning.

[0078] Specifically, when a vehicle with a leaking braking circuit stops, the air pressure value of each circuit will gradually decrease. When the engine is restarted, the leakage effect of the braking circuit can be judged according to the air pressure value. The specific operation process is as follows:

[0079] 1: Calculate the vehicle parking time.

[0080] For the time when the vehicle engine stops during parking (time_shutdown) to the time when the vehicle starts the engine (time_start), the corresponding parking time can be known as: time_parking = time_start - time_shutdown.

[0081] When the vehicle starts, the braking air pressure pressure_start at the time when the vehicle starts the engine can be obtained.

[0082] Draw a two-dimensional table with time_parking as the x-axis and pressure_start as the y-axis, and set the threshold pressure_threshold at different times.

[0083] Compare the air pressure thresholds at different parking durations. If pressure_start > pressure_threshold, it can be judged that the braking air pressure leakage of this vehicle is very small or there is no leakage.

[0084] If pressure_start < pressure_threshold, it can be judged that the braking air pressure leakage of this vehicle is large enough and a reminder or even an alarm is required.

[0085] Based on the above vehicle air pressure leakage warning method, an embodiment of the present invention further provides a vehicle air pressure leakage warning device. Please refer to Figure 4 which includes an acquisition module 410, a model construction module 420, an air pressure determination module 430, and a judgment module 440.

[0086] The acquisition module 410 is used to acquire the parking duration of the target vehicle and the braking air pressure when the target vehicle starts the engine;

[0087] The model construction module 420 is used to determine the safe air pressure range of the vehicle at different parking durations according to the preset data analysis method, and construct a relationship model between the parking duration and the safe air pressure range;

[0088] The air pressure determination module 430 is used to determine the safe air pressure range corresponding to the parking duration of the target vehicle according to the relationship model between the parking duration and the safe air pressure range;

[0089] A judgment module 440 is configured to determine the air pressure leakage state of the target vehicle according to the relationship between the braking air pressure and the safety air pressure range when starting the engine based on the current measurement.
