[0002] An air compressor is one of the core devices of a vehicle braking system, which compresses air into high-pressure gas by being driven by a motor or an engine of the vehicle to provide a high-pressure gas source for the vehicle braking system. Load rate is an important performance indicator of the air compressor.

[0003] In the conventional technology, a preset pressure value is set, and when the air pressure in the air reservoir is greater than the preset pressure value, it is determined that the air compressor is in a working state, so as to calculate the load rate of the air compressor, and then control the air compressor according to the load rate.

This method calculates the air compressor's load rate by measuring the number of time points; obtains vehicle demand information; and controls the replacement of the air compressor in the vehicle when the air compressor's load rate is not within the demand load range. Compared to the traditional method of determining whether the air compressor is in operation by setting a preset pressure value, this method obtains the extreme values ​​of air pressure in the air tank and determines whether the air compressor is in operation based on the maximum and minimum values. This allows for a more accurate determination of the air compressor's operating status, a more precise calculation of the air compressor's load rate, and the control of air compressor replacement based on the magnitude of the air compressor's load rate.

[0078] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0079] In one embodiment, such as Figure 1 As shown, a method for replacing an air compressor is provided. This method is applied to a vehicle, which includes a pressure sensor, an air reservoir, and an air compressor. The pressure sensor records the air pressure value in the air reservoir. The method includes the following steps:

[0080] Step 102: Obtain the air pressure value in the air storage tank over a preset time period using the pressure sensor; the air pressure value in the air storage tank is obtained according to the preset sampling time point.

[0081] The vehicle in question is a test vehicle, comprising a pressure sensor, an air reservoir, and an air compressor. The pressure sensor is used to record the air pressure in the air reservoir in real time.

[0082] In practice, the preset time period can be 30 minutes, and the preset sampling time point can be 0.05 seconds. Specifically, the preset time period and the preset sampling time point can be set based on actual conditions, and this invention does not impose any limitations on them.

[0083] For example, the terminal can obtain the air pressure value in the air storage tank according to the preset sampling time point within a preset time period through the pressure sensor. The obtained air pressure value in the air storage tank can form an image, which is similar to a sine function image.

[0084] Step 104: Process the data of the air pressure in the air storage tank during the preset time period to obtain the extreme values ​​of the air pressure in the air storage tank, and record the time points corresponding to the extreme values; the extreme values ​​include maximum and minimum values.

[0085] Specifically, the data processing method can be to plot the air pressure values ​​in the air storage tank at preset sampling time points within a preset time period on a coordinate system, where the X-axis can record the time points and the Y-axis can record the air pressure values ​​in the air storage tank.

[0086] For example, there can be multiple extreme values. The extreme values ​​of air pressure in the gas reservoir can be related to a maximum value and a minimum value. Specifically, the extreme values ​​of air pressure in the gas reservoir can be determined by obtaining the maximum and / or minimum values ​​of air pressure in the gas reservoir.

[0087] In one embodiment, the air pressure values ​​in the air storage tank during a preset time period are processed to obtain the extreme values ​​of the air pressure in the air storage tank, and the time points corresponding to the extreme values ​​are recorded.

[0088] Step 106: Determine the operating status of the air compressor based on the maximum and minimum values; the operating status includes the working status and the non-working status.

[0089] The operating status of the air compressor can include working status and non-working status.

[0090] For example, the air pressure in the air tank can reflect the working status of the air compressor to a certain extent. Based on the maximum and minimum values ​​of the air pressure in the air tank during a preset time period, the operating status of the air compressor during the time period corresponding to the maximum and minimum values ​​can be determined.

[0091] Step 108: Obtain the number of first time points in the preset time period where the air compressor is in the working state and the number of second time points in the preset time period where the air compressor is in the non-working state.

[0092] In practice, there are multiple time points between an adjacent maximum and minimum value.

[0093] Among them, the number of the first time point and the number of the second time point are related to the extreme values.

[0094] For example, the number of first time points in a preset time period where the air compressor is in a working state and the number of second time points in a non-working state are obtained.

[0095] Step 110: Calculate the load rate of the air compressor based on the number of the first time point and the number of the second time point.

[0096] The first time point number is the number of preset sampling time points corresponding to the air compressor's operating state within a preset time period. The second time point number is the number of preset sampling time points corresponding to the air compressor's non-operating state within a preset time period.

[0097] For example, the formula for calculating the load rate of an air compressor is:

[0098]

[0099] Where A is the load rate of the air compressor; B is the number of sampling time points when the air compressor is in the working state during the preset time period; and C is the number of sampling time points when the air compressor is in the non-working state during the preset time period.

[0100] Step 112: Obtain the demand information of the vehicle, which includes the required load range of the air compressor;

[0101] The vehicle demand information includes the air compressor's required load range. The required load range includes both the maximum and minimum required load values.

[0102] For example, the required load range of the air compressor in the vehicle can be obtained. Specifically, the maximum and minimum values ​​in the required load range are obtained based on empirical values, which are not limited herein.

[0103] Step 114: If the load rate of the air compressor is not within the required load range, control the replacement of the air compressor in the vehicle.

[0104] For example, if the air compressor's load rate is less than the minimum required load, the control will replace the current air compressor with a lower-powered one. If the air compressor's load rate is greater than the maximum required load, the control will replace the current air compressor with a higher-powered one. If the air compressor's load rate is within the required load range, there is no need to replace the air compressor in the vehicle.

[0105] In practice, when it is necessary to test whether the current air compressor meets the actual needs of the vehicle during the vehicle development phase, the load rate of a preset time period can be calculated to determine whether the air compressor in the vehicle needs to be replaced.

[0106] In the above-mentioned method for replacing the air compressor, the air pressure in the air tank during a preset time period is obtained through a pressure sensor; the air pressure values ​​in the air tank during the preset time period are processed to obtain the extreme values ​​of the air pressure in the air tank, and the time points corresponding to the extreme values ​​are recorded; the operating status of the air compressor is determined based on the maximum and minimum values; the number of first time points in the preset time period where the air compressor is in the working state and the number of second time points in the preset time period where the air compressor is in the non-working state are obtained; based on the number of first time points and the number of second time points, the air compressor is calculated. The method involves obtaining the load rate of the air compressor; acquiring vehicle demand information; and controlling the replacement of the air compressor in the vehicle when the air compressor load rate is not within the demand load range. Compared with the traditional method of determining whether the air compressor is in working condition by setting a preset pressure value, this method obtains the extreme values ​​of air pressure in the air tank and determines whether the air compressor is in working condition based on the maximum and minimum values. This allows for a more accurate determination of the air compressor's operating status, a more precise calculation of the air compressor load rate, and control of air compressor replacement based on the magnitude of the air compressor load rate.

[0107] In one embodiment, reference Figure 2 The diagram illustrates a process for determining extreme values. Step 104 includes:

[0108] Step 202: Obtain the maximum value of the air pressure in the air storage cylinder within the preset time period.

[0109] Step 204: Based on the maximum value, set a first threshold range; the first threshold range is obtained by multiplying the maximum coefficient in the first coefficient range by the maximum value and the minimum coefficient by the maximum value.

[0110] Step 206: Determine multiple maxima of air pressure in the gas storage tank based on the first threshold range.

[0111] Step 208: Determine multiple minimum values ​​based on multiple maximum values.

[0112] The first threshold range can be obtained by multiplying the maximum and minimum coefficients in the first coefficient range by the maximum value. The first threshold range is used to determine the maximum value of the gas storage tank within a preset time period. The maximum value is the maximum air pressure in the gas storage tank within the preset time period.

[0113] Under normal circumstances, the coefficients in the first coefficient range are close to 1, typically set to 0.99-0.995. This ensures that multiplying the coefficients in the first coefficient range by the maximum value yields a value in the first threshold range that is close to the maximum value, thereby determining the maximum value of the gas storage tank within the preset time period.

[0114] For example, based on the first threshold range, multiple sampling points within the first threshold range are obtained to determine the maximum value; if multiple maximum values ​​can be determined, then between two adjacent maximum values, there must be a minimum value.

[0115] In one example, the air pressure values ​​obtained in the gas storage tank over a preset time period can form an image similar to a sine function. The image is divided into multiple first threshold ranges, each containing multiple sampling points, with a maximum value existing between adjacent first threshold ranges. For example, if there is a sampling point A in the first first threshold range and a sampling point B in the second first threshold range, then there is a maximum value between sampling points A and B.

[0116] In the above embodiments, the maximum value of the air pressure in the air storage tank within a preset time period is obtained. Based on the maximum value, a first threshold range is set. Based on the first threshold range, multiple maximum values ​​of the air pressure in the air storage tank are determined, and multiple minimum values ​​are determined based on these multiple maximum values. By setting the first threshold range using the maximum value, the maximum and minimum values ​​can be determined, thereby enabling a more accurate determination of the air compressor's operating status and a more precise calculation of the air compressor's load rate.

[0117] In one embodiment, reference Figure 3 This illustrates another flowchart for determining extreme values. Step 104 includes:

[0118] Step 302: Obtain the minimum air pressure in the air storage cylinder within the preset time period.

[0119] Step 304: Based on the minimum value, set a second threshold range; the second threshold range is obtained by multiplying the maximum coefficient in the second coefficient range by the minimum value and the minimum coefficient by the minimum value.

[0120] Step 306: Determine multiple minimum values ​​of air pressure in the gas storage tank based on the second threshold range.

[0121] Step 308: Determine multiple maxima based on multiple minima.

[0122] The second threshold range can be obtained by multiplying the maximum coefficient by the minimum value and the minimum coefficient by the minimum value within the second coefficient range. The second threshold range is used to determine the minimum value of the air storage tank within a preset time period. The minimum value is the minimum air pressure in the air storage tank within the preset time period.

[0123] Under normal circumstances, the second coefficient range can be set to the same size as the first coefficient range, for example, both can be set to 0.99-0.995, so that the value in the second threshold range obtained by multiplying the coefficient by the minimum value in the second coefficient range is close to the minimum value, thereby determining the minimum value of the gas storage tank within the preset time period.

[0124] For example, the air pressure values ​​obtained in the air storage tank over a preset time period can form an image similar to a sine function. The minimum value is determined based on the sampling points of the second threshold range in the image. If multiple minimum values ​​can be determined, there must be a maximum value between two adjacent minimum values.

[0125] In the above embodiments, the minimum air pressure in the air reservoir within a preset time period is obtained. Based on the minimum value, a second threshold range is set. Based on the second threshold range, multiple minimum values ​​of the air pressure in the air reservoir are determined, and multiple maximum values ​​are determined based on the multiple minimum values. By setting the second threshold range using the minimum value, the maximum and minimum values ​​can be accurately determined, thereby enabling a more accurate determination of the air compressor's operating status and a more precise calculation of the air compressor's load rate.

[0126] In one embodiment, reference Figure 4 The diagram illustrates a flowchart for determining extreme values ​​in another embodiment. Step 104 includes:

[0127] Step 402: Obtain the maximum and minimum values ​​of the air pressure in the air storage cylinder within the preset time period.

[0128] Step 404: Based on the maximum and minimum values, set a first threshold range and a second threshold range.

[0129] The first threshold range can be obtained by multiplying the maximum coefficient by the maximum value and the minimum coefficient by the maximum value in the first coefficient range. The first threshold range is used to determine the maximum value of the air reservoir within a preset time period. The maximum value is the maximum air pressure in the air reservoir within the preset time period. The second threshold range can be obtained by multiplying the maximum coefficient by the minimum value and the minimum coefficient by the minimum value in the second coefficient range. The second threshold range is used to determine the minimum value of the air reservoir within a preset time period. The minimum value is the minimum air pressure in the air reservoir within the preset time period.

[0130] Step 406: Determine the maximum and minimum values ​​of the air pressure in the gas storage cylinder based on the first threshold range and the second threshold range.

[0131] For example, the air pressure values ​​obtained in the air storage tank over a preset time period can form an image similar to a sine function. The maximum value is determined based on the intersection of the first threshold range in the image, and the minimum value is determined based on the intersection of the second threshold in the image.

[0132] In the above embodiments, the maximum and minimum values ​​of air pressure in the air storage tank within a preset time period are obtained. Based on the maximum and minimum values, a first threshold range and a second threshold range are set. Based on the first threshold range and the second threshold range, the maximum and minimum values ​​of air pressure in the air storage tank are determined. By setting the first and second threshold ranges using the maximum and minimum values, the maximum and minimum values ​​can be determined, thereby enabling a more accurate determination of the air compressor's operating status and a more precise calculation of the air compressor's load rate.

[0133] In one embodiment, step 106 includes:

[0134] Step 1062: Under the condition that the time point corresponding to the minimum air pressure in the air storage tank is to the time point corresponding to the maximum air pressure in the air storage tank, it is determined that the air compressor is in working state.

[0135] Step 1064: When the time point corresponding to the maximum air pressure in the air storage tank is to the time point corresponding to the minimum air pressure in the air storage tank, it is determined that the air compressor is in a non-working state.

[0136] For example, from the time point corresponding to the minimum air pressure in the air tank to the time point corresponding to the maximum air pressure in the air tank, the air compressor is in a working state; from the time point corresponding to the maximum air pressure in the air tank to the time point corresponding to the minimum air pressure in the air tank, the air compressor is determined to be in a non-working state.

[0137] Specifically, upon vehicle startup, the initial air pressure value and initial time point in the air reservoir are recorded. The time point from the initial air pressure value to the time point corresponding to the minimum air pressure value in the first air reservoir indicates the air compressor is in a non-operating state. The time point from the time point corresponding to the minimum air pressure value to the time point corresponding to the maximum air pressure value in the air reservoir indicates the air compressor is in an operating state. The time point from the time point corresponding to the maximum air pressure value to the time point corresponding to the minimum air pressure value in the air reservoir indicates the air compressor is in a non-operating state. The time point from the minimum air pressure value in the last air reservoir to the time point corresponding to the final air pressure value in the air reservoir indicates the air compressor is in an operating state.

[0138] Specifically, if the minimum value between the last maximum value and the termination point of the air pressure change in the gas storage tank is within the data point of the last recorded first value, then the time point recorded at this minimum value is discarded. If it is not within the data point of the last recorded first value, then the minimum value between the last maximum value and the termination point of the air pressure change in the gas storage tank is the minimum value point.

[0139] In the above embodiments, the minimum and maximum values ​​of the air pressure in the air storage tank are used to determine whether the air compressor is in working condition, so as to accurately determine the usage status of the air compressor and more accurately calculate the load rate of the air compressor.

[0140] In one embodiment, the vehicle includes an engine, and the vehicle's demand information includes the required energy consumption range of the air compressor; the method further includes:

[0141] Obtain the air compressor's usage status, engine speed, and air compressor speed characteristic parameters within a preset time period;

[0142] The power of the air compressor is calculated based on the usage status of the air compressor during the preset time period, the speed of the engine, and the speed characteristic parameters of the air compressor.

[0143] Calculate the energy consumption of the air compressor during the preset time period based on the power of the air compressor.

[0144] If the energy consumption of the air compressor is not within the required energy consumption range, the air compressor in the vehicle shall be replaced.

[0145] The vehicle also includes an engine, and the vehicle's demand information includes the energy consumption range required by the air compressor. The air compressor's operating status includes both working and non-working states. The energy consumption range includes the maximum and minimum energy consumption values. Specifically, the maximum and minimum energy consumption values ​​are obtained based on empirical values, and this invention does not impose limitations on them.

[0146] For example, the air compressor speed can be determined based on the speed ratio between the engine and the air compressor and the engine speed; the air compressor speed characteristic parameters corresponding to the working and non-working states can be determined based on the air compressor's operating status, thereby obtaining the air compressor power. Specifically, a certain time point is selected, the engine speed at that time point is obtained, the air compressor speed at that time point can be obtained based on the engine-to-air compressor speed ratio, and the air compressor speed characteristic parameters are determined based on the air compressor's corresponding operating status at that time point, so as to calculate the air compressor power at that time point.

[0147] For example, the energy consumption of the air compressor in its operating state and its non-operating state can be calculated. When the energy consumption in the non-operating state exceeds a threshold, the control will switch the air compressor to a more energy-efficient one. Specifically, the energy consumption formula for the air compressor is:

[0148]

[0149] Where W represents the energy consumption of the air compressor; n represents the time point; p represents the power; and t represents the time.

[0150] In the above embodiments, the usage status of the air compressor, the engine speed, and the air compressor speed characteristic parameters are obtained during a preset time period to calculate the power of the air compressor during the preset time period. Based on the power of the air compressor, the energy consumption of the air compressor during the preset time period is calculated. Thus, when the energy consumption of the air compressor is not within the required energy consumption range, the air compressor in the vehicle is controlled to be replaced. By using extreme values, the usage status of the air compressor is determined more accurately, and the energy consumption of the air compressor is calculated more precisely, so as to control the replacement of the air compressor in the vehicle when the energy consumption of the air compressor is not within the required energy consumption range.

[0151] To better understand the process of air compressor load rate and energy consumption, an example is provided for reference. Figure 5 This diagram illustrates a process for calculating the load rate and energy consumption of an air compressor.

[0152] Step 502: Obtain the air pressure value of the air storage tank, engine speed, speed ratio of the engine to the air compressor, and speed characteristic parameters of the air compressor during the preset time period.

[0153] Step 504: Obtain the maximum and minimum values ​​within the preset time period, and record the time points corresponding to the maximum and minimum values.

[0154] Step 506: Based on the time points corresponding to the maximum and minimum values, determine and record the air compressor's usage status at each time point within the preset time period.

[0155] Step 508: Obtain the power of the air compressor based on the working status of the air compressor at each time point in the preset time period, the engine speed, and the air compressor speed characteristic parameters.

[0156] Step 510: Calculate the energy consumption of the air compressor based on its power.

[0157] Step 512: Based on the usage status of the air compressor at each time point during the preset time period, accumulate the number of first time points in the working state and the number of second time points in the non-working state.

[0158] Step 514: Calculate the load rate of the air compressor based on the quantity at the first time point and the quantity at the second time point.

[0159] To better understand the process of air compressor load rate and energy consumption, another example is provided for detailed explanation. (See reference...) Figure 6 This diagram illustrates another process for calculating the load rate and energy consumption of an air compressor.

[0160] Step 602: Obtain the air pressure value of the air storage tank, engine speed, speed ratio of the engine to the air compressor, and speed characteristic parameters of the air compressor during a preset time period.

[0161] Step 604: Obtain the maximum value of the air pressure in the air storage tank within a preset time period, and set a first threshold range.

[0162] Step 606: Based on the first threshold range, determine multiple maximum values ​​of air pressure in the gas storage tank and record the time points corresponding to the maximum values.

[0163] Step 608: Determine multiple minimum values ​​based on multiple maximum values.

[0164] Specifically, the minimum value between the initial air pressure point in the gas storage tank and the first maximum value is obtained; the minimum value between each maximum value point is obtained, and the corresponding time point is recorded. The minimum value between the last maximum value and the gas storage tank pressure termination point is obtained, and it is determined whether this point is among the last 20 data points. If not, the minimum value between the last maximum value and the gas storage tank pressure termination point is recorded as the minimum value; if so, the data point is discarded.

[0165] Step 610: Record the time points corresponding to multiple minimum values ​​in chronological order.

[0166] Step 612: Determine the operating status of the air compressor at each time point within the preset time period based on each maximum and minimum value.

[0167] The preset time period can be the entire working time period.

[0168] Specifically, upon vehicle startup, the initial air pressure value and initial time point in the air reservoir are recorded. The time point from the initial air pressure value to the time point corresponding to the minimum air pressure value in the first air reservoir indicates the air compressor is in a non-operating state. The time point from the time point corresponding to the minimum air pressure value to the time point corresponding to the maximum air pressure value in the air reservoir indicates the air compressor is in an operating state. The time point from the time point corresponding to the maximum air pressure value to the time point corresponding to the minimum air pressure value in the air reservoir indicates the air compressor is in a non-operating state. The time point from the minimum air pressure value in the last air reservoir to the time point corresponding to the final air pressure value in the air reservoir indicates the air compressor is in an operating state.

[0169] Step 614: Record the working status of the air compressor at each point in time.

[0170] Specifically, based on the usage status of the air compressor at each time point within a preset time period, the number of first time points in the working state and the number of second time points in the non-working state are accumulated respectively.

[0171] Step 616: Obtain the power of the air compressor based on the working status of the air compressor at each time point in the preset time period, the engine speed, and the air compressor speed characteristic parameters.

[0172] Step 618: Calculate the energy consumption of the air compressor based on its power.

[0173] Step 620: Calculate the load rate of the air compressor based on the working status at each time point.

[0174] To better understand the air compressor replacement process, an example will be provided. (Refer to...) Figure 7 The diagram shows a flowchart of another method for replacing an air compressor.

[0175] Step 702: Obtain the air pressure value in the air storage tank for a preset time period using a pressure sensor; the air pressure value in the air storage tank is obtained according to the preset sampling time point.

[0176] Step 704: Obtain the maximum value of air pressure in the air reservoir within a preset time period; set a first threshold range based on the maximum value; determine multiple maxima of air pressure in the air reservoir based on the first threshold range; determine multiple minima based on the multiple maxima; or, obtain the minimum value of air pressure in the air reservoir within a preset time period; set a second threshold range based on the minimum value; determine multiple minima of air pressure in the air reservoir based on the second threshold range; determine multiple maxima based on the multiple minima.

[0177] Specifically, the first threshold range is obtained by multiplying the maximum coefficient by the maximum value and the minimum coefficient by the maximum value in the first coefficient range; the second threshold range is obtained by multiplying the maximum coefficient by the minimum value and the minimum coefficient by the minimum value in the second coefficient range.

[0178] Step 706: Determine that the air compressor is in working condition between the time point corresponding to the minimum air pressure in the air storage tank and the time point corresponding to the maximum air pressure in the air storage tank.

[0179] Step 708: Under the condition that the time point corresponding to the maximum air pressure in the air storage tank is to the time point corresponding to the minimum air pressure in the air storage tank, it is determined that the air compressor is in a non-working state.

[0180] Step 710: Obtain the number of first time points in the preset time period where the air compressor is in the working state and the number of second time points in the preset time period where the air compressor is in the non-working state.

[0181] Step 712: Calculate the load rate of the air compressor based on the quantity at the first time point and the quantity at the second time point; if the load rate of the air compressor is not within the required load range, control the replacement of the air compressor in the vehicle.

[0182] Step 714: Obtain the air compressor's operating status, engine speed, and air compressor speed characteristic parameters during a preset time period to calculate the air compressor's power.

[0183] Step 716: Calculate the energy consumption of the air compressor during a preset time period based on the power of the air compressor; if the energy consumption of the air compressor is not within the required energy consumption range, control the replacement of the air compressor in the vehicle.

[0184] In this embodiment, the air pressure in the air reservoir is obtained through a pressure sensor over a preset time period. The air pressure values ​​within the reservoir are processed to obtain extreme values, and the corresponding time points are recorded. The operating status of the air compressor is determined based on the maximum and minimum values. The number of first time points in the preset time period where the air compressor is in a working state and the number of second time points in the preset time period where the air compressor is not in a working state are obtained. The load rate of the air compressor is calculated based on the first and second time point counts. Vehicle demand information is obtained. If the air compressor load rate is not within the required load range, the air compressor in the vehicle is replaced. Compared to the traditional method of determining whether the air compressor is in a working state by setting a preset pressure value, this method obtains the extreme values ​​of the air pressure in the reservoir and determines whether the air compressor is in a working state based on the maximum and minimum values. This allows for a more accurate determination of the air compressor's operating status and a more precise calculation of the air compressor load rate. Furthermore, the air compressor replacement control is achieved based on the magnitude of the load rate.
