Description

Technical Field

[0001] This invention relates to the field of tire pressure monitoring technology, specifically to a tire pressure monitoring method and system. Background Technology

[0002] Tire pressure, strictly speaking, refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car; engine damage leads to the end of the car's lifespan. Similarly, tire pressure is like the blood pressure of the car; its level plays a crucial role in the car's performance and power.

[0003] Patent application CN103085613B discloses a tire pressure detection method. The method involves a tire pressure display device that detects and reports information, informing the user of the detection results via video and voice broadcast, and providing warnings that can directly correct errors and detect malfunctions in the tire pressure detection module. The tire pressure display device includes a main unit module, multiple tire pressure detection modules, and a vehicle audio module. The main unit module includes a central processing unit and a receiver. Through the combination of these components, it can actively report the tire position and tire pressure when the tire is inflated, and simultaneously execute video and voice broadcasts, as well as provide warnings that can directly correct errors and detect malfunctions in the tire pressure detection module.

[0004] During tire pressure testing, the internal tire pressure value and the value given by the sensor can usually be directly confirmed to determine whether the tire pressure is normal. However, due to the aging of the vehicle's tire sensors and insufficient power, false alarms or errors in judgment may occur, causing problems in the tire pressure testing process and thus affecting its accuracy. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a tire pressure detection method and system that solves the problem of false alarms or erroneous judgments caused by the aging of vehicle tire sensors and insufficient power.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tire pressure monitoring system, comprising:

[0007] The tire pressure parameter acquisition end collects the tire pressure parameters generated by the tire pressure sensor and the tire pressure parameters obtained from external detection. The tire pressure parameters obtained from external detection are calibrated as external tire pressure parameters, and the tire pressure parameters generated by the tire pressure sensor are calibrated as internal tire pressure parameters. The external tire pressure parameters and internal tire pressure parameters are then transmitted to the tire pressure abnormality judgment end.

[0008] The tire pressure anomaly detection unit determines whether the received external and internal tire pressure parameters are consistent. If they are consistent, it directly analyzes whether the tire pressure is normal. If they are inconsistent, it identifies the error. If the error is too large, it executes the subsequent pulse signal analysis. The specific method is as follows:

[0009] External tire pressure parameter calibrated to WT i The internal tire pressure parameter is calibrated to NT. i , where i represents different objects being detected;

[0010] Determine WT i Does it meet the following criteria: WT i =NT i If the conditions are met, then this tire pressure parameter WT is determined. i or NT i If the tire pressure meets the standard, no action is taken; if it does not meet the standard, an abnormal tire pressure signal is generated and displayed on the display device.

[0011] Determine WT i and NT i Does it satisfy: |WT i -NT i |>Y1, where Y1 is a preset value. If this is satisfied, it indicates that the error is too large and there is an anomaly, generating an execution instruction to execute the subsequent pulse signal analysis center. If this is not satisfied, then WT is determined. i If the tire pressure meets the standard, no action is taken; otherwise, an abnormal tire pressure signal is generated and displayed on the display. The tire pressure standard is a set of preset ranges.

[0012] The pulse signal analysis center collects the wireless modulated pulse signal that generates this internal tire pressure parameter. Then, it collects past pulse signals generated by this tire pressure sensor from the vehicle's infotainment system. Analyzing these past pulse signals determines the standard peak range and standard slope range, thus determining whether the tire pressure sensor is functioning correctly. The specific method is as follows:

[0013] S1. Construct the waveforms generated by the pulse signals previously produced by this tire pressure sensor, and sequentially confirm the peak value FZ of each waveform. k And the valley values ​​GZ1 on both sides k and GZ2 k Where k represents different waveforms, using The slope parameter XL1 generated between the peak value and different valley values ​​is obtained. k and XL2 k T1 is FZ k With GZ1 kThe time difference between them, where T2 is FZ k With GZ2 k The time difference between the two slope parameters XL1 k and XL2 k Within the range, select the maximum value and label the selected maximum value as the standard slope BX. k ;

[0014] S2, FZ of several sets of peak values ​​generated by different waveforms k and standard slope BX k After averaging, standard peak B1 and standard parameter B2 are obtained, which will then satisfy: The waveform is calibrated as a standard waveform; otherwise, it will satisfy: or The waveform is calibrated as a floating waveform, where X1 and X2 are both preset values;

[0015] S3. Determine the peak value FZ within several standard waveforms. k The maximum and minimum values ​​are used to construct a standard peak interval, and then several standard slopes BX within the standard waveform are determined. k The maximum and minimum values ​​are used to construct a standard slope interval;

[0016] S4. Reconfirm the wireless modulation pulse signal that generates this internal tire pressure parameter, then confirm the waveform generated by this wireless modulation pulse signal, confirm the peak value of this waveform, and define it as the "pulse peak value". Then, in the same way as in step S1, confirm the standard slope of this wireless modulation pulse signal waveform and define it as the "pulse slope".

[0017] S5. Confirm whether the pulse peak value and pulse slope both meet the following conditions: pulse peak value ∈ standard peak value range and pulse slope ∈ standard slope range. If both conditions are met, it means that the wireless modulation pulse signal generated by this tire pressure sensor is a normal fluctuation signal. At the same time, a speed test signal is generated and transmitted to the periodic speed analysis center. If one condition is not met or neither condition is met, it means that this tire pressure sensor may be abnormal, and a sensor abnormality signal is generated and transmitted to the external display terminal for external personnel to view.

[0018] Preferably, it also includes a periodic speed analysis center, which directly extracts wheel speed parameters generated within the past 6 hours from the vehicle's infotainment system based on the speed test signal, assigns different labels to different wheel speed parameters, determines the number of the tire to be tested, and labels the wheel speed parameters generated by this tire as the parameters to be verified, and checks whether these parameters to be verified are normal; the specific method is as follows:

[0019] The average of several sets of parameters to be verified generated by the tire under test over the past 6 hours is calculated and denoted as HD. The wheel speed parameters generated by other wheels are determined, and the average of the different wheel speed parameters for each corresponding wheel is calculated and denoted as JD. t , where t represents different wheels;

[0020] Lock in several more JD groups t The mean value JZ is then analyzed to determine if HD satisfies the condition: |HD-JZ|>Y2, where Y2 is a preset value. If satisfied, the corresponding tire under test is marked as an abnormal tire, and an abnormal tire pressure signal is generated and displayed. If not satisfied, it means that there is a false alarm during the tire pressure detection process of this tire under test, and the generated value is not accurate. It may be caused by tire temperature or other factors, and no processing is required.

[0021] Preferably, a tire pressure monitoring method includes the following steps:

[0022] Step 1: Collect the tire pressure parameters generated by the tire pressure sensor and the tire pressure parameters obtained from external detection, and determine whether the two sets of tire pressure parameters are consistent. If they are consistent, directly analyze whether the tire pressure is normal. If they are inconsistent, determine the error. If the error is too large, execute the subsequent pulse signal analysis center.

[0023] Step 2: The pulse signal analysis center collects the wireless modulated pulse signal that generates this internal tire pressure parameter. Then, it collects the pulse signals previously generated by this tire pressure sensor from the vehicle's infotainment system, analyzes the previously generated pulse signals, determines the standard peak range and standard slope range, and reconfirms the wireless modulated pulse signal that generates this internal tire pressure parameter to determine whether the peak value and slope of the pulse signal meet the corresponding standard conditions. If they meet the conditions, subsequent testing and processing are performed; if they do not meet the conditions, a sensor abnormality signal is directly generated and displayed.

[0024] Step 3: Extract the wheel speed parameters generated within the past 6 hours directly from the vehicle's infotainment system, mark the different wheel speed parameters differently, determine the number of the tire to be tested, and mark the wheel speed parameters generated by this tire to be tested as the parameters to be verified. Check whether this parameter to be verified is normal and determine whether the tire pressure of this tire to be tested is normal.

[0025] Beneficial effects

[0026] This invention provides a tire pressure monitoring method and system. Compared with the prior art, it has the following advantages:

[0027] This invention acquires and confirms the tire pressure inside the tire, determining whether two sets of tire pressure parameters are consistent. If inconsistencies exist, it examines the past signal waveforms generated by the tire pressure sensor. By analyzing the differences between the current signal and past signals, it identifies the valleys and peaks between different signals. Signals with drastic fluctuations are prioritized for removal. After removal, the corresponding standard waveform is determined. Since a large number of standard waveforms show high similarity, a corresponding standard range can be identified. The peak value and standard value of the current waveform are then analyzed to determine if they fall within the corresponding standard range. If they do, the current waveform conforms to the corresponding standard; otherwise, it does not. This indicates a problem with the tire pressure sensor, and a corresponding signal is generated for external inspection. This allows for timely detection and replacement of the tire pressure sensor, improving the comprehensiveness of the tire pressure detection process. It not only confirms whether the tire pressure of the object being tested is problematic but also identifies whether the internal tire pressure sensor is functioning correctly.

[0028] To confirm whether there are any false alarms in tire pressure parameters during tire inspection, the rotation speed of the corresponding tire is taken into account and analyzed. This analysis confirms whether the tire pressure is abnormal based on the abnormal rotation speed, making the inspection process more comprehensive and effective. Attached Figure Description

[0030] Figure 2 This is a waveform diagram of the pulse signal of the present invention. Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figure 1 This application provides a tire pressure monitoring system, including a tire pressure parameter acquisition terminal, a tire pressure abnormality judgment terminal, a pulse signal analysis center, a cycle speed analysis center, and a display terminal;

[0034] The tire pressure parameter acquisition terminal is electrically connected to the tire pressure anomaly determination terminal input node, and the tire pressure anomaly determination terminal is electrically connected to the pulse signal analysis center input node. The pulse signal analysis center is electrically connected to the periodic speed analysis center input node, and the tire pressure anomaly determination terminal, the pulse signal analysis center, and the periodic speed analysis center are all electrically connected to the display terminal input node.

[0035] The tire pressure parameter acquisition terminal collects tire pressure parameters generated by the tire pressure sensor and tire pressure parameters obtained from external detection. The tire pressure parameters obtained from external detection are calibrated as external tire pressure parameters, and the tire pressure parameters generated by the tire pressure sensor are calibrated as internal tire pressure parameters. The external tire pressure parameters and internal tire pressure parameters are transmitted to the tire pressure anomaly determination terminal. When performing tire pressure detection, the external instrument can acquire and confirm the tire pressure inside the tire. At the same time, the corresponding tire pressure sensor inside the tire will also generate tire pressure. Therefore, two sets of tire pressure parameters can be directly collected. The internal tire pressure parameters can be obtained from the vehicle system.

[0036] The tire pressure anomaly detection terminal determines whether the received external and internal tire pressure parameters are consistent. If they are consistent, it directly analyzes whether the tire pressure is normal. If they are inconsistent, it identifies the error. If the error is too large, it executes the subsequent pulse signal analysis center. The specific method for anomaly detection is as follows:

[0037] External tire pressure parameter calibrated to WT i The internal tire pressure parameter is calibrated to NT. i , where i represents different objects being detected;

[0038] Determine WT i Does it meet the following criteria: WT i =NT i If the conditions are met, then this tire pressure parameter WT is determined. i or NT i If the tire pressure meets the standard, no action is taken; if it does not meet the standard, an abnormal tire pressure signal is generated and displayed on the display device.

[0039] Determine WT i and NT i Does it satisfy: |WT i -NT i |>Y1, where Y1 is a preset value, the specific value of which is determined by the operator based on experience. If it is satisfied, it indicates that the error is too large and there is an anomaly, and an execution instruction is generated to execute the subsequent pulse signal analysis center. If it is not satisfied, then WT is determined. iIf the tire pressure meets the standard, no action is taken; otherwise, an abnormal tire pressure signal is generated and displayed on the display. The tire pressure standard is a set of preset ranges, and the specific values ​​are determined by the operator based on experience.

[0040] Specifically, in a normal analysis process, only one set of tire pressure parameters needs to be monitored. However, for some older or older vehicles, the internal tire pressure sensors may have some problems. When they are aging or have insufficient power, it is easy to cause errors in the internal tire pressure parameters, and their accuracy is greatly affected. Therefore, by using the above analysis method, we can make a preliminary judgment on whether there is a problem with the tire pressure sensor, improve the comprehensiveness of the tire pressure detection process, and not only confirm whether there is a problem with the tire pressure of the corresponding object being tested, but also identify whether the internal tire pressure sensor is working properly.

[0041] The pulse signal analysis center collects the wirelessly modulated pulse signal that generates this internal tire pressure parameter. Then, it collects past pulse signals generated by the tire pressure sensor from the vehicle's infotainment system, analyzes these past pulse signals, and determines the standard peak range and standard slope range. The pulse signal waveform is as follows: Figure 2 As shown, the specific method for determining the interval is as follows:

[0042] S1. Construct the waveforms generated by the pulse signals previously produced by this tire pressure sensor, and sequentially confirm the peak value FZ of each waveform. k And the valley values ​​GZ1 on both sides k and GZ2 k Where k represents different waveforms, using The slope parameter XL1 generated between the peak value and different valley values ​​is obtained. k and XL2 k T1 is FZ k With GZ1 k The time difference between them, where T2 is FZ k With GZ2 k The time difference between the two slope parameters XL1 k and XL2 k Within the range, select the maximum value and label the selected maximum value as the standard slope BX. k ;

[0043] S2, FZ of several sets of peak values ​​generated by different waveforms k and standard slope BX k After averaging, standard peak B1 and standard parameter B2 are obtained, which will then satisfy: The waveform is calibrated as a standard waveform; otherwise, it will satisfy: or The waveform is calibrated as a floating waveform, where X1 and X2 are preset values, and their specific values ​​are determined by the operator based on experience.

[0044] S3. Determine the peak value FZ within several standard waveforms. k The maximum and minimum values ​​are used to construct a standard peak interval, and then several standard slopes BX within the standard waveform are determined. k The maximum and minimum values ​​are used to construct a standard slope interval;

[0045] S4. Reconfirm the wireless modulation pulse signal that generates this internal tire pressure parameter, then confirm the waveform generated by this wireless modulation pulse signal, confirm the peak value of this waveform, and define it as the "pulse peak value". Then, in the same way as in step S1, confirm the standard slope of this wireless modulation pulse signal waveform and define it as the "pulse slope".

[0046] S5. Confirm whether the pulse peak value and pulse slope both meet the following conditions: pulse peak value ∈ standard peak value range and pulse slope ∈ standard slope range. If both conditions are met, it means that the wireless modulation pulse signal generated by this tire pressure sensor is a normal fluctuation signal. At the same time, a speed test signal is generated and transmitted to the periodic speed analysis center. If one condition is not met or neither condition is met, it means that this tire pressure sensor may be abnormal. A sensor abnormality signal is generated and transmitted to the external display terminal for external personnel to view.

[0047] Specifically, to confirm whether the sensor inside the tire is working properly, it is necessary to analyze the difference between the signal generated this time and the signals generated in the past. From the signals generated in the past, the valleys and peaks of different signals are identified. Signals with drastic fluctuations are removed first. After removal, the corresponding standard waveform can be determined. Since a large number of standard waveforms are highly similar, the corresponding standard range can be determined from a large number of standard waveforms. Then, the peak value and standard value generated by the current waveform are analyzed to determine whether it belongs to the corresponding standard range. If it does, it means that the current waveform meets the corresponding standard. If it does not, it means that the current waveform does not meet the corresponding standard, and the tire pressure sensor has a corresponding problem. The corresponding signal is then generated and displayed for external personnel to check, so that the tire pressure sensor can be checked in time, the problem can be determined, and it can be replaced in time, thus improving the comprehensiveness of this system in the tire pressure detection process.

[0048] The cycle speed analysis center, based on the speed test signal, directly extracts the wheel speed parameters generated within the past 6 hours from the vehicle's infotainment system, assigns different labels to different wheel speed parameters, determines the number of the tire to be tested, and labels the wheel speed parameters generated by this tire as the parameters to be verified. It then checks whether these parameters are normal. The specific method is as follows:

[0049] The average of several sets of parameters to be verified generated by the tire under test over the past 6 hours is calculated and denoted as HD. The wheel speed parameters generated by other wheels are determined, and the average of the different wheel speed parameters for each corresponding wheel is calculated and denoted as JD. t , where t represents different wheels;

[0050] Lock in several more JD groups t The mean value JZ is then analyzed to determine whether HD satisfies the condition: |HD-JZ|>Y2, where Y2 is a preset value, the specific value of which is determined by the operator based on experience. If this condition is met, the corresponding tire under test is marked as an abnormal tire, an abnormal tire pressure signal is generated and displayed. If this condition is not met, it means that there is a false alarm during the tire pressure detection process of this tire under test, and the generated value is not accurate. It may be caused by tire temperature or other factors, and no processing is required.

[0051] Specifically, if a tire has too low or too high tire pressure, during normal rotation, if the tire pressure is lower than other tires, the tire will rotate faster because the entire tire is smaller, thus rotating faster. Conversely, the same principle applies. During normal analysis, if the rotation speed of a tire deviates significantly, it indicates an abnormal tire pressure signal, which should be addressed promptly. Tire pressure testing is a more comprehensive and effective method.

If they are consistent, directly analyze whether the tire pressure is normal. If they are inconsistent, determine the error. If the error is too large, execute the subsequent pulse signal analysis center.

[0055] Step 2: The pulse signal analysis center collects the wireless modulated pulse signal that generates this internal tire pressure parameter. Then, it collects the pulse signals previously generated by this tire pressure sensor from the vehicle's infotainment system, analyzes the previously generated pulse signals, determines the standard peak range and standard slope range, and reconfirms the wireless modulated pulse signal that generates this internal tire pressure parameter to determine whether the peak value and slope of the pulse signal meet the corresponding standard conditions. If they meet the conditions, subsequent testing and processing are performed; if they do not meet the conditions, a sensor abnormality signal is directly generated and displayed.
