[0080] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0081] With the rapid development of the vehicle industry and the improvement of people's living standards, people have higher and higher requirements for vehicle functions. For example, when a vehicle with high off-road performance, such as an SUV (Sport Utility Vehicle), is driving on muddy, gravel, desert or snowy roads, users expect to change the internal pressure of the tire to improve the tire's ground adhesion, so that the vehicle has good passability when driving on muddy, gravel, desert, snowy roads, etc., thereby ensuring driving comfort.

[0082] It is understandable that, in order to inflate the tire, the user usually needs to use an inflation device such as an air pump. Furthermore, to meet the needs of users, the vehicle can be equipped with an external inflation system that can inflate inflatable objects outside the vehicle, so as to inflate and manage inflatable objects such as tires, inflatable rubber boats, and inflatable beds.

[0083] However, since inflatable objects such as tires, inflatable rubber boats, and inflatable beds are usually not equipped with components such as air pressure sensors, when inflating these inflatable objects, how to obtain the internal air pressure value of the inflatable object to determine whether the expected air pressure inside the inflatable object has been reached has become one of the main design difficulties of the external inflation system.

[0084] In the related art, the traditional solution for obtaining the internal air pressure value of an inflatable object is to set up an air pressure sensor to detect the air pressure value of the inflation pipeline, that is, when the air pump inflates the inflatable object through the inflation pipeline, the air pressure sensor value is read as the internal air pressure of the inflatable object. It can be understood that although this solution can obtain the internal air pressure of the inflatable object during the inflation process, the internal air pressure obtained is the air pressure detection value of the air pressure sensor for the inflation pipeline during the inflation process, which has a large delay and error compared to the actual internal air pressure of the inflated object, and if the internal pressure value of the inflatable object fails to reach the target pressure value, the object needs to be inflated a second time, resulting in low inflation efficiency.

[0085] Based on the above problems you may encounter, please refer to Figure 1 , the present application embodiment provides an inflation control method, comprising:

[0086] 01: When the inflatable device inflates the inflatable object, obtain state parameter information of the inflatable device;

[0087] 02: Control the inflation device according to the status parameter information.

[0088] The embodiment of the present application provides an electronic device, which includes a memory and a processor. The inflation control method of the embodiment of the present application can be implemented by the electronic device of the embodiment of the present application. Specifically, a computer program is stored in the memory, and the processor is used to obtain state parameter information of the inflatable device when the inflatable device inflates the inflatable object, and control the inflatable device according to the state parameter information.

[0089] Specifically, in an embodiment of the present application, the electronic device can obtain state parameter information of the inflatable device such as operating voltage, operating current, etc. when the inflatable device is inflating an inflatable object, and control the inflatable device according to the state parameter information, such as controlling the inflatable device to stop inflating the inflatable object or to continue inflating the inflatable object.

[0090] In one example, the inflation device includes an air pump or the like.

[0091] In one example, the inflated object includes an inflatable object such as a vehicle tire, an inflatable rubber boat, an inflatable bed, etc.

[0092] In one example, the status parameter information of the inflatable device includes the operating current, operating voltage, operating power, etc. of the inflatable device.

[0093] In one example, the electronic device can estimate the internal air pressure of the inflated object based on the state parameter information of the inflating device. For example, when the inflating device is a vehicle tire, the tire pressure of the vehicle tire can be estimated based on the state parameter information of the inflating device. Then, when the tire pressure does not reach a preset value, the electronic device can control the inflating device to continue inflating the vehicle tire, and when the tire pressure reaches a preset value, the electronic device can control the inflating device to stop inflating the vehicle tire.

[0094] In one example, the electronic device is an ECU (Electronic Control Unit).

[0095] In this way, in the embodiments of the present application, the state parameter information of the inflatable device can be obtained when the inflatable device is inflating the inflatable object, and the inflatable device can be controlled according to the state parameter information of the inflatable device, thereby realizing inflation control when the inflatable object is not provided with an air pressure sensor, and because the control of the inflatable device is realized based on the state parameter information of the inflatable device, there is no need for the user to manually control the inflatable device, thereby avoiding the user judging the inflation effect of the object based on personal experience to control the inflation, which may cause the inflated object to be under-inflated or over-inflated, thereby ensuring the user's use of the inflatable object to a certain extent.

[0096] See also Figure 2 In certain embodiments of the present application, step 02 includes:

[0097] 020: predicting the inflation state of the inflated object according to the state parameter information;

[0098] 021: Control the inflation equipment according to the inflation status.

[0099] The processor of the embodiment of the present application is also used to predict the inflation state of the inflated object according to the state parameter information, and to control the inflation device according to the inflation state.

[0100] Specifically, in the embodiment of the present application, the electronic device can predict the inflation state of the inflatable object based on the state parameter information of the inflatable device, such as predicting whether the inflatable object has enough gas. In addition, the electronic device can also control the operation of the inflatable device based on the predicted inflation state.

[0101] In one example, the inflation status of the inflatable device is divided into two types, one is fully charged, and the other is not fully charged.

[0102] Furthermore, in one example, the electronic device may predict the inflation state of the inflated object at the current moment based on the state parameter information of the inflatable device, and control the control device to stop inflating if the inflation state of the inflated object at the current moment is fully charged; if the inflation state of the inflated object at the current moment is not fully charged, control the control device to continue inflating the inflated object until the inflated object becomes fully charged at a certain moment in the inflation state.

[0103] In one example, the electronic device may input state parameter information of the inflatable device into a neural network model deployed in a local or remote server, so that the neural network model predicts the inflation state of the inflatable object based on the state parameter information of the inflatable device. Furthermore, the electronic device may control the inflatable device based on the inflation state of the inflatable object predicted by the model.

[0104] Thus, in the embodiment of the present application, the inflation state of the inflatable object can be predicted according to the state parameter information of the inflatable device, and the inflatable device can be controlled according to the inflation state of the inflatable object, thereby achieving control of the inflatable device.

[0105] In certain embodiments of the present application, the inflated state includes internal air pressure.

[0106] Specifically, the electronic device can predict the internal air pressure of the inflatable object according to the state parameter information of the inflatable device, and then control the inflatable device according to the internal air pressure of the inflatable object.

[0107] It can be understood that in the embodiments of the present application, the internal air pressure of the inflated object can be predicted based on the state parameter information of the inflatable device. Furthermore, even if the inflated object does not have a built-in air pressure sensor, the internal air pressure of the inflated object during the inflation process can be determined, and the inflatable device can be controlled based on the internal air pressure, thereby ensuring reliable control of the inflation process to a certain extent.

[0108] In this way, in the embodiment of the present application, the internal air pressure of the inflated object can be predicted based on the state parameter information of the inflatable device, and the internal air pressure of the inflated object can be detected when the inflated object does not have a built-in air pressure sensor. In addition, the control of the inflatable device can be achieved based on the internal air pressure of the inflated object, thereby ensuring reliable control of the inflatable device and the inflation process to a certain extent.

[0109] See also Figure 3 In some embodiments of the present application, the inflatable device includes a motor, and then step 020 includes:

[0110] 0200: Determine the air pressure compensation coefficient and the motor torque of the inflatable device according to the state parameter information;

[0111] 0201: Determine the internal air pressure based on the air pressure compensation coefficient and motor torque.

[0112] The processing unit of the embodiment of the present application is also used to determine the air pressure compensation coefficient and the motor torque of the inflatable device according to the state parameter information, and to determine the internal air pressure according to the air pressure compensation coefficient and the motor torque.

[0113] Specifically, in the implementation manner of the present application, the air pressure compensation coefficient and the motor torque of the inflatable device can be determined according to the state parameter information, and the internal air pressure of the inflated object can be determined based on the air pressure compensation coefficient and the motor torque of the inflatable device.

[0114] In one example, the air pressure compensation coefficient is used to indicate the compensation of "the actual inflation state of the inflatable device for the inflated object at the current moment" relative to "the ideal inflation state of the inflatable device for the inflated object at the current moment" during the inflation process of the inflatable device.

[0115] It can be understood that, under an ideal inflation environment, the inflation device can inflate the same volume of gas into the inflated object at different times, while in an actual inflation environment, as the inflation device continuously inflates the inflated object, the inflation pressure of the inflated object increases with time. Accordingly, as the inflation pressure of the inflated object gradually increases, the "resistance hindering the gas from entering the interior of the inflated object" exerted by the inflated object on the gas in the inflation device (or the air path between the inflatable device and the inflated object) also gradually increases.

[0116] It is also understandable that the resistance may affect the operation effect of the inflatable device to a certain extent, thereby affecting the inflatable state of the inflatable device for the inflated object, and causing the volume of gas inflated by the inflatable device to be different at different times. Therefore, in the embodiment of the present application, the air pressure compensation coefficient and the motor torque of the inflatable device may be determined according to the state parameter information, thereby predicting the internal air pressure of the inflated object.

[0117] In one example, the electronic device may determine the air pressure compensation coefficient and the motor torque corresponding to the state parameter information by looking up the table based on a pre-stored mapping table.

[0118] In one example, the electronic device may use the state parameter information as an input parameter of a pre-implemented function for calculating the air pressure compensation coefficient and the motor torque, and determine the air pressure compensation coefficient and the motor torque corresponding to the state parameter information through the return value of the function.

[0119] In this way, in the embodiment of the present application, the air pressure compensation coefficient and the motor torque of the inflatable device can be determined according to the state parameter information of the inflatable device, and the internal air pressure of the inflated object can be determined according to the air pressure compensation coefficient and the motor torque of the inflatable device, thereby realizing the prediction of the internal air pressure of the inflated object.

[0120] See also Figure 4 In some embodiments of the present application, the state parameter information includes a first operating voltage, a first operating current, and a first motor speed when the inflatable device is inflated at a current duty cycle. Then, step 0200 includes:

[0121] 02000: determining a first operating power of the inflatable device according to the first operating voltage and the first operating current;

[0122] 02001: Determine a first motor torque of the inflatable device according to a first operating power and a first motor speed;

[0123] 02002: Determine the motor torque according to the first motor torque and the motor radius of the motor.

[0124] The processor of the embodiment of the present application is also used to determine the first operating power of the inflatable device based on the first operating voltage and the first operating current, and to determine the first motor torque of the inflatable device based on the first operating power and the first motor speed, and to determine the motor torque based on the first motor torque and the motor radius of the motor.

[0125] Specifically, in the embodiment of the present application, the electronic device can determine the motor torque of the motor in the inflatable device according to the first operating voltage, the first operating current and the first motor speed of the inflatable device at the current duty cycle of the inflatable device.

[0126] For example, let the current duty cycle of the inflatable device be A'%, and let the operating current, operating voltage and motor speed of the inflatable device when inflating the inflatable object at the current duty cycle A' be I', U', n' respectively, then:

[0127] First, based on the operating current I' and the operating voltage U' when the inflatable device inflates the inflatable object at the current duty cycle A'%, the operating power P' when the inflatable device inflates the inflatable object at the current duty cycle A'% can be determined by multiplying the operating current I' and the operating voltage U', where P'=I'×U'.

[0128] Next, based on the operating power P' when the inflatable device inflates the inflatable object at the current duty cycle A'%, and the motor speed n' when the inflatable device inflates the inflatable object at the current duty cycle A'%, the motor torque T' when the inflatable device inflates the inflatable object at the current duty cycle A'% can be determined by the operating power P', the motor speed n' and the constant 9550, where P'×9550=T'×n'.

[0129] Finally, based on the motor torque T' when the inflatable device inflates the inflatable object at the current duty cycle A'%, and the motor radius r of the motor 电 , then the torque F' of the inflatable device's motor when it works at the motor speed n' can be determined, where F'=T' / r 电 .

[0130] Thus, in the embodiment of the present application, the first operating power of the inflatable device can be determined according to the first operating voltage and the first operating current, the first motor torque of the inflatable device can be determined according to the first operating power and the first motor speed, and the motor torque of the motor in the charging device can be determined according to the first motor torque and the motor radius of the motor, thereby achieving the determination of the motor torque.

[0131] See also Figure 5 In certain embodiments of the present application, the state parameter information includes a second operating voltage, a second operating current, and a second motor speed when the inflatable device is inflated at a preset duty cycle. Then, step 0200 includes:

[0132] 02003: Determine a second operating power of the inflatable device according to the second operating voltage and the second operating current;

[0133] 02004: Determine a second motor torque of the inflatable device according to the second operating power and the second motor speed;

[0134] 02005: Determine the gas pressure compensation coefficient according to the second motor torque and the second motor speed.

[0135] Specifically, in the embodiment of the present application, the electronic device can determine the air pressure compensation coefficient according to the operating voltage, operating current and motor speed when the inflatable device inflates the inflatable object with a preset duty cycle.

[0136] For example, assuming that the preset duty cycles include A1%, A2%, and A3%, and assuming that the operating current, operating voltage, and motor speed of the inflatable device when inflating the inflatable object at the preset duty cycle A1% are I1, U1, and n1, respectively. Similarly, assuming that the operating current, operating voltage, and motor speed of the inflatable device when inflating the inflatable object at the current duty cycle A2% are I2, U2, and n2, respectively, and the operating current, operating voltage, and motor speed of the inflatable device when inflating the inflatable object at the current duty cycle A3% are I3, U3, and n3, respectively, then:

[0137] First, based on the operating current I1 and the operating voltage U1 when the inflatable device inflates the inflatable object at the preset duty cycle A1%, the operating power P1 of the inflatable device when the inflatable object is inflated at the preset duty cycle A1% can be determined by multiplying the operating current I1 and the operating voltage U1, where P1=I1×U1. Similarly, the operating powers P2 and P3 of the inflatable device when the inflatable object is inflated at the preset duty cycles A2% and A3% can be obtained.

[0138] Next, based on the operating power P1 when the inflatable device inflates the inflatable object at the preset duty cycle A1%, and the motor speed n1 when the inflatable device inflates the inflatable object at the preset duty cycle A1%, the motor torque T1 when the inflatable device inflates the inflatable object at the preset duty cycle A1% can be determined by the operating power P1, the motor speed n1 and the constant 9550, wherein P1×9550=T1×n1. Similarly, the motor torques T1 and T2 when the inflatable device inflates the inflatable object at the preset duty cycles A2% and A3% can be obtained.

[0139] Finally, the air pressure compensation coefficient K' can be determined based on the motor speeds n1, n2, n3 when the charging device inflates the inflatable object at the preset duty cycles A1%, A2%, A3%, and the motor torques T1, T2, T3 when the charging device inflates the inflatable object at the preset duty cycles A1%, A2%, A3%.

[0140] In one example, the air pressure compensation coefficient K' is calculated by the following formula:

[0141]

[0142] Thus, in the embodiment of the present application, the second operating power of the inflatable device can be determined according to the second operating voltage and the second operating current, and the second motor torque of the inflatable device can be determined according to the second operating power and the second motor speed, and: the air pressure compensation coefficient can be determined according to the second motor torque and the second motor speed, thereby realizing the determination of the air pressure compensation coefficient.

[0143] See also Figure 6 In some implementations of the present application, step 0201 includes:

[0144] 02010: Determine the air resistance of the inflated object to the inflating air path according to the air pressure compensation coefficient and the motor torque;

[0145] 02011: Determine internal air pressure based on air resistance.

[0146] The processor of the embodiment of the present application is also used to determine the air resistance of the inflated object to the air path for inflation based on the air pressure compensation coefficient and the motor torque, and to determine the internal air pressure based on the air resistance.

[0147] Specifically, in the embodiments of the present application, the air resistance of the inflated object to the air path for inflation can be determined based on the air pressure compensation coefficient and the motor torque of the motor in the charging device, and the internal air pressure of the inflated object can be determined based on the air resistance of the inflated object to the air path for inflation.

[0148] In one example, the air resistance is used to indicate the resistance applied by the inflated object to the gas in the inflation gas path, which prevents the gas from entering the interior of the inflated object.

[0149] In one example, the “air resistance of the inflated object to the air path for inflation” is positively correlated with the “internal air pressure of the inflated object”.

[0150] Thus, in the embodiment of the present application, the air resistance of the inflated object to the inflating air path can be determined according to the air pressure compensation coefficient and the motor torque, and the internal air pressure of the inflated object can be determined according to the air resistance of the inflated object to the inflating air path, thereby realizing the prediction of the internal air pressure of the inflated object.

[0151] In some embodiments of the present application, step 02010 includes:

[0152] The air resistance is determined based on the air pressure compensation coefficient, the motor torque and a predetermined air pressure relationship coefficient.

[0153] The processor in the implementation manner of the present application is also used to determine the air resistance based on the air pressure compensation coefficient, the motor torque and the predetermined air pressure relationship coefficient.

[0154] Specifically, in the embodiment of the present application, the electronic device can determine the air resistance of the inflated object to the inflation air path according to the air pressure compensation coefficient, the motor torque of the inflation device, and the predetermined air pressure relationship coefficient.

[0155] In one example, the air resistance of the inflated object can be calculated by the following formula:

[0156] F′ 阻 =ζ*F'+K'

[0157] In the formula, F′ 阻 It represents the air resistance of the inflated object, F' represents the motor torque of the inflatable equipment, and K' represents the air pressure compensation coefficient.

[0158] Thus, in the embodiment of the present application, the air resistance of the inflatable object to the inflation air path can be determined according to the air pressure compensation coefficient, the motor torque of the inflation device and the predetermined air pressure relationship coefficient.

[0159] In certain embodiments of the present application, the inflation control method further includes:

[0160] When the inflatable device inflates the inflatable object, the air pressure relationship coefficient is determined according to the internal air pressure detection value and the internal air pressure expected value of the inflatable object.

[0161] The processor of the embodiment of the present application is also used to determine the air pressure relationship coefficient according to the internal air pressure detection value and the expected internal air pressure value of the inflated object when the inflatable device inflates the inflated object.

[0162] Specifically, in the embodiment of the present application, the electronic device may determine the air pressure relationship coefficient according to the internal air pressure detection value of the inflated object when the inflatable device inflates the inflatable object and the expected internal air pressure value of the inflated object.

[0163] For example, firstly, the expected inflation pressure P of the inflated object can be calculated or simulated to determine the expected inflation pressure P of the inflated object after the inflatable device inflates the inflated object with a unit volume of gas in an ideal inflation scenario. std Then, after controlling the inflation device to inflate a unit volume of gas into the inflated object, the inflated object is subjected to air pressure detection to obtain the actual inflation pressure P now Finally, according to the desired inflation pressure P std and the actual inflation pressure P now Fitting is performed to obtain the above air pressure relationship coefficients.

[0164] In one example, the air pressure relationship coefficient may be determined based on a detected internal air pressure value and an expected internal air pressure value of the inflatable object when the inflatable device is powered on for the first time to inflate the inflatable object.

[0165] In one example, the air pressure relationship coefficient may be determined based on a detected internal air pressure value and an expected internal air pressure value of the inflatable object when the inflatable device is powered on for the first time after maintenance to inflate the inflatable object.

[0166] Thus, in the embodiment of the present application, when the inflatable device inflates the inflatable object, the air pressure relationship coefficient can be determined according to the internal air pressure detection value and the expected internal air pressure value of the inflatable object, thereby determining the air pressure relationship coefficient.

[0167] In some embodiments of the present application, step 02011 includes:

[0168] The internal air pressure is determined based on the air resistance and the radius of the air inlet interface of the inflated object.

[0169] The processor of the embodiment of the present application is also used to determine the internal air pressure based on the air resistance and the air inlet interface radius of the inflated object.

[0170] Specifically, in the embodiment of the present application, the electronic device can determine the internal air pressure of the inflated object according to the air resistance of the inflated object to the inflating air path and the interface radius of the air inlet interface of the inflated object.

[0171] In one example, the internal pressure of the inflated object can be calculated by the following formula:

[0172]

[0173] Among them, P′ 估 Indicates the internal pressure of the inflated object, F' 阻 Indicates the air resistance of the inflated object, r 管 Indicates the radius of the air inlet interface of the inflated object.

[0174] Thus, in the embodiment of the present application, the internal air pressure of the inflated object can be determined according to the air resistance of the inflated object and the air inlet interface radius of the inflated object, thereby realizing the prediction of the internal air pressure of the inflatable device.

[0175] In some embodiments of the present application, step 020 includes:

[0176] When the internal air pressure is greater than or equal to a preset pressure, controlling the inflatable device to stop inflating; and / or,

[0177] When the internal air pressure is lower than the preset pressure, the inflatable device is controlled to continue inflating.

[0178] The electronic device of the embodiment of the present application is also used to control the inflatable device to stop inflating when the internal air pressure is greater than or equal to the preset pressure, and / or control the inflatable device to continue inflating when the internal air pressure is less than the preset pressure.

[0179] Specifically, in an embodiment of the present application, when the electronic device predicts the internal air pressure of an inflatable object based on state parameter information of the inflatable device, when it is determined that the inflatable object has achieved the desired inflation effect based on the internal air pressure of the inflatable object, that is, when the internal air pressure of the inflatable object is greater than or equal to a preset pressure, the inflatable device is controlled to stop inflating the inflatable object to avoid the inflatable object being inflated with too much gas.

[0180] In addition, the electronic device can also control the inflation device to continue inflating the inflated object to avoid insufficient inflation of the inflated object when it determines based on the internal air pressure of the inflated object that the inflated object has not yet achieved the desired inflation effect, that is, when the internal air pressure of the inflated object is less than a preset pressure.

[0181] Thus, in an embodiment of the present application, the inflation device can be controlled to stop inflating the inflated object when the internal air pressure is greater than or equal to the preset pressure, and / or the inflation device can be controlled to continue inflating the inflated object when the internal air pressure is less than the preset pressure, thereby achieving reliable control of the inflation device and the inflation process.

[0182] In addition, when the electronic device predicts the internal air pressure of the inflated object according to the state parameter information of the inflatable device, it can feedback prompt information to prompt the user when the internal air pressure of the inflated object is greater than or equal to another preset pressure.

[0183] For example, let the ideal internal pressure of the inflated object be P std , the electronic device can broadcast a voice message of "filled" through its own sound unit to prompt the user when the internal air pressure of the inflated object is greater than or equal to P1.

[0184] For example, let the ideal internal pressure of the inflated object be P std , the electronic device can broadcast a voice message of "about to be filled" through its own sound unit to remind the user when the internal air pressure of the inflated object is greater than or equal to P2, where P2 is less than P std , and P2 and P std The difference is a preset smaller value.

[0185] In certain embodiments of the present application, the inflation control method further includes:

[0186] The inflation device is controlled according to the current air pressure of the air circuit being inflated.

[0187] The processor of the embodiment of the present application is also used to control the inflation device according to the current air pressure of the air circuit for inflation.

[0188] Specifically, in an embodiment of the present application, an air pressure sensor may be provided on the air path between the inflatable device and the inflated object, and then, the electronic device may control the inflatable device to continue to inflate the inflatable object or stop inflating the inflatable object according to the current air pressure detected by the air pressure sensor.

[0189] It can be understood that in the embodiments of the present application, the electronic device can control the inflatable device through the state parameter information of the inflatable device, and can also control the inflatable device through the current air pressure of the air path between the inflatable device and the inflated object. Therefore, the inflatable device can be controlled in two ways, thereby achieving redundancy of the control of the inflatable device, thereby avoiding the situation where the inflatable device and the inflation process cannot be controlled when the inflatable device cannot be controlled by the state parameter information of the inflatable device, or when the inflatable device cannot be controlled by the current air pressure of the air path between the inflatable device and the inflated object.

[0190] In this way, in the implementation mode of the present application, the inflatable device can be controlled according to the state parameter information of the inflatable device, and the inflatable device can also be controlled according to the current air pressure of the air circuit for inflating the inflatable device, thereby achieving redundant control of the inflatable device, and further ensuring the controllability of the inflatable device and the inflation process.

[0191] In certain embodiments of the present application, the above-mentioned inflatable device is controlled according to the current air pressure of the inflatable air circuit, including:

[0192] The inflatable device is controlled according to the current air pressure of the air circuit when the inflatable device stops inflating.

[0193] The processor of the embodiment of the present application is also used to control the inflatable device according to the current air pressure of the air circuit when the inflatable device stops inflating.

[0194] Specifically, in an embodiment of the present application, the inflatable device can be controlled to stop inflating during the inflation process, so that the "current air pressure in the air path between the inflatable device and the inflated object" can be equivalent to the "inflation pressure of the inflated object". Furthermore, when the inflatable device is controlled by the "current air pressure in the air path between the inflatable device and the inflated object", accurate and effective control of the inflatable device can be guaranteed.

[0195] In one example, when the "current air pressure of the air path between the inflatable device and the inflated object" does not reach the desired air pressure of the inflated object, the inflatable device is controlled to continue to inflate the inflated object. And, when the "current air pressure of the air path between the inflatable device and the inflated object" reaches the desired air pressure of the inflated object, the inflatable device is maintained in a state of stopping inflating the inflated object.

[0196] Thus, in the embodiment of the present application, the inflatable device can be controlled according to the current air pressure of the air circuit when the inflatable device stops inflating, thereby ensuring that the current air pressure of the air circuit is effective and reliable in controlling the inflatable device.

[0197] In certain embodiments of the present application, the inflation control method further includes:

[0198] In response to the inflation control instruction, the inflation device is controlled to inflate the inflatable object.

[0199] The processor of the embodiment of the present application is also used to control the inflation device to inflate the inflatable object in response to the inflation control instruction.

[0200] Specifically, in the implementation mode of the present application, the electronic device can respond to the inflation control instructions triggered by the user through the control panel, display components and other devices, control the inflatable device to inflate the inflatable object, and control the inflatable device according to the state parameter information of the inflatable device when it is inflated.

[0201] In one example, the inflation control instruction includes the desired air pressure of the inflated object. Then, the electronic device can control the inflation device to inflate the inflated object according to the inflation control instruction so that the inflation pressure of the inflated object matches the desired air pressure, or in other words, the inflation pressure of the inflated object and the desired air pressure are within a preset allowable range.

[0202] In one example, the inflation control instruction includes a desired air pressure value of the inflated object, and a message including a unit for indicating the desired air pressure value. Then, the electronic device can convert the desired air pressure value into an expected air pressure value of a preset air pressure unit based on the desired air pressure value and the message for indicating the unit of the expected air pressure value, and calculate the expected air pressure value of the preset air pressure unit.

[0203] For example, in the inflation control instruction, the expected air pressure value of the inflated object is 1. The electronic device determines that the unit of the expected air pressure value is kPa (kilopascal) based on the message used to indicate the unit of the expected air pressure value in the inflation control instruction. Then, when the preset air pressure unit is Pa (Pascal), the electronic device can convert the expected air pressure value (i.e., 1) in the inflation control instruction into an air pressure value under the unit of Pa, i.e., 1000, and control the inflation device to inflate the inflated object according to the air pressure value of 1000.

[0204] Thus, in the embodiment of the present application, the inflatable device can be controlled to inflate the inflatable object in response to the inflation control instruction, thereby controlling the inflatable device to inflate the inflatable object.

[0205] See also Figure 7 Corresponding to the above-mentioned inflation control method, an embodiment of the present application further provides an inflation system 100, which includes an inflation device 101, an inflated object 102 and a controller 103. The controller 103 is connected to the inflation device 101, and the controller 103 is configured to control the inflation device 101 to inflate the inflated object 102 to implement the above-mentioned inflation control method.

[0206] Specifically, in the embodiment of the present application, the controller 103 can control the inflatable device 101 to inflate the inflatable object 102 , and control the inflatable device 101 according to state parameter information when the inflatable device 101 inflates the inflatable object 102 .

[0207] In one example, the inflatable device 101 includes an air pump or the like.

[0208] In one example, the inflated object 102 includes an inflatable object such as a vehicle tire, an inflatable rubber boat, an inflatable bed, etc.

[0209] In one example, the status parameter information of the inflatable device 102 includes the operating current, operating voltage, operating power, etc. of the inflatable device 102 .

[0210] In one example, the controller 103 can estimate the internal air pressure of the inflated object 102 based on the state parameter information of the inflatable device 101. For example, when the inflatable device 101 is a vehicle tire, the tire pressure of the vehicle tire can be estimated based on the state parameter information of the inflatable device 101. Then, when the tire pressure does not reach a preset value, the controller 103 can control the inflatable device 101 to continue inflating the vehicle tire, and when the tire pressure reaches a preset value, the controller 103 can control the inflatable device 101 to stop inflating the vehicle tire.

[0211] In one example, the controller 103 is an ECU (Electronic Control Unit).

[0212] In one example, the controller 103 includes the electronic device described above.

[0213] It can be understood that the specific process of the controller 103 controlling the inflatable device 101 according to the state parameter information when the inflatable device 101 inflates the inflatable object 102 can refer to the contents of each step in the above-mentioned inflation method, and each step in the above-mentioned inflation method can be implemented by the controller 103 in the embodiment of the present application. To avoid repetition, it will not be described in detail here.

[0214] In this way, the inflation system 100 provided in the embodiment of the present application can obtain the state parameter information of the inflatable device 101 when the inflatable device 101 inflates the inflatable object 102, and control the inflatable device 101 according to the state parameter information of the inflatable device 101, thereby realizing inflation control when the inflatable object 102 is not provided with an air pressure sensor, and, because the control of the inflatable device 101 is realized based on the state parameter information of the inflatable device 101, there is no need for the user to manually control the inflatable device 101, thereby avoiding the user judging the inflation effect of the object based on personal experience to control the inflation, which may cause the inflatable object 102 to be under-inflated or over-inflated, thereby ensuring the user's use of the inflatable object 102 to a certain extent.

[0215] In some embodiments of the present application, the system 100 further includes an air pressure sensor 104 connected to the controller 103, the air pressure sensor 104 is configured to detect the current air pressure of the air circuit 105 for inflation, and the controller 103 is configured to control the inflatable device 101 according to the current air pressure of the air circuit 105 for inflation.

[0216] Specifically, in the embodiment of the present application, the controller 103 is also connected to an air pressure sensor 104, which is used to detect the current air pressure of the air path 105 between the inflatable device 101 and the inflated object 102. Then, the controller 103 can control the inflatable device 101 according to the current air pressure of the air path 105.

[0217] It can be understood that in the embodiment of the present application, the controller 103 can control the inflatable device 101 through the state parameter information of the inflatable device 101, and can also control the inflatable device 101 through the current air pressure of the air path 105 between the inflatable device 101 and the inflated object 102. Therefore, the inflatable device 101 can be controlled in two ways, thereby achieving redundancy in the control of the inflatable device 101, thereby avoiding the situation where the inflatable device 101 and the inflation process cannot be controlled when the inflatable device 101 cannot be controlled by the state parameter information of the inflatable device 101, or when the inflatable device 101 cannot be controlled by the current air pressure of the air path 105 between the inflatable device 101 and the inflated object 102.

[0218] In this way, in the embodiment of the present application, the current air pressure of the air path 105 between the inflatable device 101 and the inflated object 102 can be detected based on the air pressure sensor 104, and then, the inflatable device 101 can be controlled according to the state parameter information of the inflatable device 101, and the inflatable device 101 can also be controlled according to the current air pressure of the air path 105 for inflating the inflatable device 101, thereby achieving redundant control of the inflatable device 101, and then ensuring the controllability of the inflatable device 101 and the inflation process.

[0219] Optionally, in one example, the controller 103 may control the inflatable device 101 according to the current air pressure of the air circuit 105 when the inflatable device 101 stops inflating. Specifically, in the embodiment of the present application, the controller 103 may control the inflatable device 101 to stop inflating during the inflation process, so that "the current air pressure of the air circuit 105 between the inflatable device 101 and the inflated object 102 detected by the air pressure sensor 104" may be equivalent to the "inflation air pressure of the inflated object 102", and then, when the inflatable device 101 is controlled by the "current air pressure of the air circuit 105 between the inflatable device 101 and the inflated object 102", the accurate and effective control of the inflatable device 101 can be guaranteed.

[0220] In one example, when the “current air pressure of the air path 105 between the inflatable device 101 and the inflated object 102” does not reach the desired air pressure of the inflatable object 102, the inflatable device 101 is controlled to continue to inflate the inflatable object 102. And, when the “current air pressure of the air path 105 between the inflatable device 101 and the inflated object 102” reaches the desired air pressure of the inflatable object 102, the inflatable device 101 is maintained in a state of stopping inflating the inflatable object 102.

[0221] In some embodiments of the present application, the inflation system 100 further includes an interactive device connected to the controller 103 .

[0222] Specifically, in an embodiment of the present application, the inflation system 100 also includes an interactive device connected to the controller 103, and then, the user can send instructions to the controller 103 through the interactive device, such as sending an inflation control instruction to the controller 103 through the interactive device, so that the controller 103 controls the inflation device 101 to inflate the inflatable object 102 according to the inflation control instruction.

[0223] In one example, the inflation control instruction includes the desired air pressure of the inflated object 102. Then, the controller 103 can control the inflation device 101 to inflate the inflated object 102 according to the inflation control instruction so that the inflation pressure of the inflated object 102 matches the desired air pressure, or in other words, the inflation pressure of the inflated object 102 is within a preset allowable range with the desired air pressure.

[0224] In one example, the inflation control instruction includes a desired air pressure value of the inflated object 102, and a message including a unit for indicating the desired air pressure value. Then, the controller 103 can convert the desired air pressure value into an expected air pressure value of a preset air pressure unit based on the desired air pressure value and the message for indicating the unit of the expected air pressure value, and according to the expected air pressure value of the preset air pressure unit.

[0225] For example, in the inflation control instruction, the expected air pressure value of the inflated object 102 is 1, and the controller 103 determines that the unit of the expected air pressure value is kPa (kilopascal) based on the message used to indicate the unit of the expected air pressure value in the inflation control instruction. Then, when the preset air pressure unit is Pa (Pascal), the controller 103 can convert the expected air pressure value (i.e. 1) in the inflation control instruction into an air pressure value under the unit of Pa, i.e. 1000, and control the inflation device 101 to inflate the inflated object 102 according to the air pressure value of 1000.

[0226] Thus, in the implementation mode of the present application, interaction with the user can be performed through the interactive device.

[0227] In some embodiments of the present application, the interactive device includes a control panel 106 connected to the controller 103 , and / or includes a display component 107 connected to the controller 103 .

[0228] Specifically, in the embodiment of the present application, the user may interact via a control panel 106 connected to the controller 103 and / or a display component 107 connected to the controller 103 .

[0229] In one example, the display component 107 includes a vehicle dashboard and / or a vehicle multimedia center console.

[0230] Thus, in the embodiment of the present application, interaction with the user can be achieved through the control panel 106 and / or the display component 107 .

[0231] In some embodiments of the present application, the control panel 106 includes an inflation interface, and the inflation device 101 inflates the inflatable object 102 through the inflation interface.

[0232] Specifically, in the embodiment of the present application, when the interactive device includes a control panel 106, the control panel 106 may also include an inflation interface, and then the inflatable device 101 can be connected to the inflatable object 102 through the inflation interface, and inflate the inflatable object 102 through the inflation interface.

[0233] In this way, in the embodiment of the present application, the inflatable device 101 can inflate the inflatable object 102 through the inflation interface of the control panel 106 .

[0234] To more clearly describe the inflation system 100 in the embodiment of the present application, please refer to Figure 7 , Figure 8 as well as Fig. 9 , Figure 8 and Fig. 9 These are schematic diagrams of application scenarios in certain embodiments of the present application. Figure 8 As shown, first, after the controller 103 is powered on, the inflation system 100 deployed on the vehicle and the vehicle inflation function supported by the inflation system 100 are started.

[0235] Then, after the vehicle inflation function is started, the inflation system 100 is in a dormant (standby) state. The system 100 communicates with the control panel 106 and the display component 107 via the CAN (Controller Area Network) bus of the controller 103, thereby obtaining the inflation control command input by the user on the control panel 106 or the display component 107, and the system 100 starts to execute the vehicle inflation function.

[0236] Then, the system 100 directly obtains the target pressure value of the inflated object 102 and the relevant message of the corresponding pressure unit selection sent by the control panel 106 or the display component 107 through the vehicle CAN bus, and controls the inflation of the inflated object 102 according to the target pressure value of the inflated object 102 and the corresponding pressure unit.

[0237] Then, the system 100 controls the inflatable device 101 to start, and at the same time, the air pressure sensor 104 on the air circuit 105 collects the pressure value in real time.

[0238] Next, the high-pressure gas output by the inflatable device 101 flows along the gas path 105 , sequentially passes through the air pressure sensor 104 and the inflatable interface of the control panel 106 , and flows to the inflated object 102 .

[0239] Next, the system 100 performs the following steps: Fig. 9 The pressure estimation method of the inflated object 102 shown in the figure obtains the estimated pressure value of the inflated object 102 (i.e. the internal air pressure mentioned above), or the controller 103 collects the pressure value in the air circuit 105 (i.e. the current pressure mentioned above) in real time through the air pressure sensor 104 on the air circuit 105. At this time, the air circuit 105 of the system 100 structure collected by the air pressure sensor 104 is normally the air pressure in the space of "inflatable device 101--air circuit 105--air pressure sensor 104--inflating interface of control panel 106--inflated object 102", so that the estimated pressure value of the inflated object 102 can be obtained.

[0240] Subsequently, the system 100 determines whether the current pressure value of the inflatable object 102 reaches the target pressure value of the inflatable object 102 according to the estimated pressure value of the inflatable object 102 .

[0241] Then, when the estimated pressure value of the inflated object 102 reaches the target pressure value, the system 100 controls the inflating device 101 to close, and feeds back the inflation completion status to the control panel 106, the vehicle instrument and the multimedia central control screen. At this point, the normal inflation control of the system 100 ends.

[0242] Finally, the system 100 ends the vehicle inflation function and enters a dormant (standby) state.

[0243] like Fig. 9 As shown, first, the system 100 obtains the external inflation control instruction sent by the control panel 106 or the display component 107 through the CAN bus, and the system 100 starts the inflation control and begins to estimate the pressure value of the inflated object 102.

[0244] Next, the system 100 collects the operating current I', the operating voltage U' and the motor speed n' when the inflatable device 101 inflates the inflatable object 102 at the current duty cycle A'%.

[0245] Next, the system 100 controls the air pump to adjust the duty cycle of the air pump so that the duty cycles of the air pump are A1%, A2% and A3% respectively. The system 100 can collect the operating current I1 when the inflatable object 102 is inflated with the duty cycle A1%. Similarly, the operating currents I2 and I3 can be obtained when the air pump inflates the inflatable object 102 with the duty cycles A2% and A3%.

[0246] Then, the system 100 obtains the operating power P' of the inflatable device 101 when it inflates the inflatable object 102 at the current duty cycle A'% according to the collected operating current I' and operating voltage U' when the inflatable device 101 inflates the inflatable object 102 at the current duty cycle A'%, by P'=I'×U'. Similarly, the operating powers P1, P2, and P3 of the inflatable device 101 when it inflates the inflatable object 102 at the duty cycle A1%, the duty cycle A2%, and the duty cycle A3% can be obtained respectively.

[0247] Then, the system 100 obtains the motor speed n' when the inflatable device 101 inflates the inflatable object 102 at the current duty cycle A'% based on the collected data, combined with the operating power P' when the inflatable device 101 inflates the inflatable object 102 at the current duty cycle A'%, and the motor torque T' when the inflatable device 101 inflates the inflatable object 102 at the current duty cycle A'% is obtained by P'×9550=T'×n'.
