Description

Technical Field

[0001] The present invention relates to the field of vehicles, and in particular to a tire pressure control method, device, system and vehicle. Background Art

[0002] During vehicle driving, tire pressure that is too high or too low will shorten the tire's service life and indirectly affect the vehicle's key performance such as power, smoothness, handling and braking. Therefore, reasonable tire pressure is crucial to the tire and even the vehicle.

[0003] At present, during the inflation / deflation process of the tire, the user is required to pay attention to the tire pressure at all times with the help of a display instrument. When the tire pressure reaches the target pressure, the user actively ends the inflation or deflation operation, resulting in overpressure / underpressure still existing after the tire is inflated / deflated.

[0094] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0095] See also Figure 1 , Figure 1 Schematic diagram of a tire pressure control system provided by this application. Figure 1 As shown, the tire pressure control system 10 includes a controller 11 and a tire pressure sensor 12. The controller 11 is used to calculate a target pressure 13 of the tire and send the target pressure 13 to the tire pressure sensor 12. The tire pressure sensor 12 is used to receive an inflation / deflation request 15 sent by an inflation / deflation device 14, receive the target pressure 13, generate a start instruction 16 and an end instruction 17 based on the target pressure 13, and send the start instruction 16 or the end instruction 17 to the inflation / deflation device 14. The start instruction 16 is used to instruct the inflation / deflation device 14 to inflate or deflate the tire. The end instruction 17 is used to instruct the inflation / deflation device 14 to end the inflation or deflation operation on the tire.

[0096] Based on the aforementioned tire pressure control system, a tire pressure control method provided by the present application is specifically introduced below.

[0097] See also Figure 2 , Figure 2 is a flow chart of a tire pressure control method provided by the present application. Figure 2 As shown, the tire pressure control method provided by the present application includes:

[0098] S201: The inflation / deflation device generates an inflation / deflation request and sends the inflation / deflation request to the tire pressure sensor.

[0099] Among them, the filling / deflation equipment can be Figure 1 In the filling / deflation device 14, the filling / deflation request can be Figure 1 The tire pressure sensor is used to monitor and collect tire pressure (tire pressure) in real time, which can be Figure 1 The tire pressure sensor 12 in the tire pressure control system 10 in FIG.

[0100] In some possible implementations, the inflation / deflation device communicates with the tire pressure sensor using Bluetooth, wireless fidelity (WiFi), ultra wide band (UWB), etc., to transmit the inflation / deflation request.

[0101] In some possible implementations, the inflation / deflation request includes first request information, wherein the first request information is used to request the controller to determine a target pressure of the tire and to request the tire pressure sensor to determine a type of a start instruction.

[0102] In some other possible implementations, the inflation / deflation request includes the second request information and the inflation information, or the inflation / deflation request includes the second request information and the deflation information. The second request information is used to request the controller to determine the target pressure of the tire. The inflation information is used to request the tire pressure sensor to generate an inflation start instruction. The deflation information is used to request the tire pressure sensor to generate a deflation start instruction. The inflation / deflation request includes at least the following two implementations:

[0103] In a specific implementation, a user can input inflation information or deflation information on the display interface of the inflation / deflation device according to driving experience or driving needs, and the inflation / deflation device generates a corresponding inflation / deflation request according to the inflation information or deflation information, and sends the inflation / deflation request to the tire pressure sensor.

[0104] In another specific implementation, a controller installed on a vehicle determines the type of information contained in the inflation / deflation request by comparing the first pressure of the tire with the standard pressure of the tire when it leaves the factory. The first pressure of the tire is the tire pressure collected in real time by the tire pressure sensor, or the first pressure of the tire is the tire pressure collected regularly by the tire pressure sensor. Specifically, the controller receives the first pressure sent by the tire pressure sensor, and compares the first pressure with the standard pressure of the tire when it leaves the factory stored in the controller. When the first pressure of the tire is less than the standard pressure of the tire when it leaves the factory, and the difference between the two is greater than a first threshold, the controller generates an inflation notification. When the first pressure of the tire is greater than the standard pressure of the tire when it leaves the factory, and the difference between the two is greater than a second threshold, the controller generates a deflation notification. The controller displays the inflation notification or deflation notification to the user through the display interface of the vehicle, and then the user inputs the corresponding inflation information or deflation information on the display interface of the inflation / deflation device, and the inflation / deflation device generates the corresponding inflation / deflation request according to the inflation information or deflation information, and sends the inflation / deflation request to the tire pressure sensor. Alternatively, the controller sends an inflation notification or a deflation notification to the tire pressure sensor, and the tire pressure sensor sends an inflation notification or a deflation notification to the inflation / deflation device. If the inflation / deflation device receives the inflation notification, the inflation / deflation device generates an inflation / deflation request including the second request information and the inflation information; if the inflation / deflation device receives the deflation notification, the inflation / deflation device generates an inflation / deflation request including the second request information and the deflation information. Subsequently, the inflation / deflation device sends an inflation / deflation request to the tire pressure sensor. Alternatively, the controller sends an inflation notification or a deflation notification to the tire pressure sensor, and the tire pressure sensor sends an inflation notification or a deflation notification to the inflation / deflation device, and the inflation / deflation device displays the inflation notification or the deflation notification to the user through the display interface of the inflation / deflation device, and then the user inputs the corresponding inflation information or deflation information on the display interface of the inflation / deflation device, and the inflation / deflation device generates the corresponding inflation / deflation request according to the inflation information or the deflation information, and sends the inflation / deflation request to the tire pressure sensor. The tire pressure sensor and the controller communicate using Bluetooth, wireless fidelity (WiFi), ultra wide band (UWB), etc. The controller can be Figure 1 The controller 11 in the tire pressure control system 10.

[0105] S202: The controller calculates and obtains first information.

[0106] In some possible implementations, the first information includes mileage, tire load, tread depth, etc. The mileage is calculated based on wheel speed and time. The tire load is calculated based on tire pressure, tire temperature, inner wall angular acceleration, and radial deformation. The tread depth is calculated based on tire pressure, tire temperature, and inner wall radial acceleration. The wheel speed is monitored and collected by a wheel speed sensor installed in the tire, the driving time is generated by an internal clock installed on the vehicle, and the tire pressure, tire temperature, inner wall angular acceleration, radial deformation, and inner wall radial acceleration are monitored and collected by a tire pressure sensor. Wheel speed, driving time, tire pressure, tire temperature, inner wall angular acceleration, radial deformation, inner wall radial acceleration, etc. can be collected either regularly or periodically.

[0107] In some possible implementations, the calculation results of the mileage, tire load, and tread depth are stored in the controller, and can be updated regularly, or can be updated regularly, or can be updated under specified conditions. For example, the tire load is calculated when the tire load is greater than a tire load threshold, or the tread depth is calculated when the tread depth is less than a tread depth threshold.

[0108] It should be understood that the present technical solution can either execute the above step S201 first, and then execute the above step S202; or execute the above step S202 first, and then execute the above step S201.

[0109] S203: The tire pressure sensor sends an inflation / deflation request to the controller.

[0110] S204: When receiving the inflation / deflation request, the controller calculates the target pressure based on the first information.

[0111] In some possible implementations, the controller calculates the target pressure based on the first information. The target pressure may be Figure 1 The target pressure 13 in the tire pressure control system 10 in the first information is calculated by the controller using the mileage, tire load, and tread depth in the first information to obtain the mileage coefficient, tire load coefficient, and tread depth coefficient, and then the mileage coefficient, tire load coefficient, and tread depth coefficient are used to calculate the target pressure. The target pressure includes at least the following two implementation methods:

[0112] In a specific implementation, the target pressure can be expressed as:

[0113] F(t)=[a0+a1*c1(t)+a2*c2(t)+a3*c3(t)]*F0(t)

[0114] Where F(t) represents the target pressure at time t, a0, a1, a2, and a3 are coefficients, and a0+a1+a2+a3=1, c1(t) represents the mileage coefficient at time t, c2(t) represents the tire load coefficient at time t, c3(t) represents the tread depth coefficient at time t, and F0(t) represents the base pressure at time t. Specifically, c1(t)∈{s1,s2,…,s p}, where s i represents the mileage coefficient corresponding to the ith mileage range. Therefore, the mileage coefficient corresponding to the mileage range of the vehicle at time t is the mileage coefficient at time t, that is, the specific value of c1(t). For example, when the ith mileage range is 0-500 kilometers, s i =1.0; in the case where the ith mileage range is 500-1000 km, s i = 0.9; when the i-th mileage range is 1000-1500 kilometers, s i =0.8. c2(t)∈{w1,w2,…,w q}, where w i represents the tire load coefficient corresponding to the i-th tire load range. Therefore, the tire load coefficient corresponding to the tire load range of the tire load at time t is the tire load coefficient at time t, that is, the specific value of c2(t). For example, when the i-th tire load range is 120-150 kg, w i =1.0; when the i-th tire load range is 90-120 kg, w i = 0.9; when the i-th tire load range is 60-90 kg, w i =0.8. c3(t)∈{d1,d2,…,d r}, where d i represents the tread depth coefficient corresponding to the i-th tread depth range. Therefore, the tread depth coefficient corresponding to the tread depth range of the tire at time t is the tread depth coefficient at time t, that is, the specific value of c3(t). For example, when the i-th tread depth range is 8-10 mm, d i =1.0; when the tread depth of the i-th tire is in the range of 6-8 mm, d i = 0.9; when the tread depth of the i-th tire is in the range of 4-6 mm, d i =0.8.

[0115] In another specific implementation, the target pressure can be expressed as:

[0116] F(t)=[a0+a1*c1(y)*c2(t)*c3(t)]*F0(y)

[0117] Wherein, F(t) represents the target pressure at time t, a0 and a1 are coefficients, and a0+a1=1, c1(t) represents the mileage coefficient at time t, c2(t) represents the tire load coefficient at time t, c3(t) represents the tread depth coefficient at time t, and F0(t) represents the basic pressure at time t.

[0118] In some possible implementations, the base pressure F0(t) at time t includes at least the following four implementations:

[0119] In a specific implementation, the controller calculates the base pressure F0(t) at time t based on the second information, and therefore, the controller calculates the target pressure based on the first information and the second information. The second information is determined by the user, including driving weather (such as sunny, cloudy, rainy, snowy, hail, storm, sandstorm, etc.), driving temperature (such as -4.9~0℃, 0~4.9℃, 5~9.9℃, etc.), driving road conditions (such as normal road surface, sand, snow, grass, etc.), driving experience (such as maneuverability, smoothness, braking, etc.), etc. The user can input the second information through the display interface of the inflation / deflation device, and the inflation / deflation device sends the second information to the tire pressure sensor, and then the tire pressure sensor sends the received second information to the controller. Alternatively, the user can input the second information through the display interface of the vehicle, and the vehicle sends the second information to the controller. Therefore, the base pressure F0(t) at time t can be expressed as:

[0120] F0(t)=[b0+b1*u1(t)+b2*u2(t)+…+b m *u m (t)]*F0

[0121] Among them, F0(t) represents the base pressure at time t, b0, b1, b2, ... b m are coefficients, and b0+b1+b2+…+b m =1, F0 represents the standard pressure of the tire when it leaves the factory, u i (t) represents the coefficient corresponding to one of the driving weather, driving temperature, driving road conditions, driving experience, etc. at time t. i (t) represents the driving road condition coefficient at time t, u i (t)∈{r1,r2,…,r l}, where r j represents the driving condition coefficient corresponding to the jth specific description content. Therefore, the driving condition coefficient corresponding to the specific description content of the driving condition at time t is the driving condition coefficient at time t, that is, u iFor example, when the jth specific description content is a normal road surface, r j = 1.0; when the jth specific description is sand, r j = 1.2; when the jth specific description is snow, r j =0.7.

[0122] In another specific implementation, the controller calculates the basic pressure F0(t) at time t based on the third information, and therefore, the controller calculates the target pressure based on the first information and the third information. The third information is used to describe the vehicle attributes and tire attributes, including vehicle type (such as a single compartment vehicle type, a two-compartment vehicle type, a two-compartment and a half vehicle type, a three-compartment vehicle type, a micro, small, medium vehicle type, a large, compact vehicle type, a CDV vehicle type, an MPV vehicle type, an SUV vehicle type, etc.), tire model (such as a car tire, a light truck tire, a truck and a bus tire, an agricultural vehicle tire, an engineering vehicle tire, an industrial vehicle tire, an aircraft tire, a motorcycle tire, etc.), the standard pressure of the tire when it leaves the factory, and the like. The above tire model can also be represented by parameters such as the tire's cross-sectional width, the ratio of the sidewall height to the cross-sectional width, and the tire structure (such as a cross-layer tire, a radial layer tire). The third information is stored in the controller. Therefore, the basic pressure F0(t) at time t can be expressed as:

[0123] F0(t)=[g0+g1*p1+g2*p2+…+g n *p n ]*F0

[0124] Among them, F0(t) represents the base pressure at time t, g0, g1, g2, ... g n is a coefficient, and g0+g1+g2+…+g n =1, F0 represents the standard pressure of the tire when it leaves the factory, p i represents the coefficient corresponding to one of the vehicle type, tire model, etc. For example, in p i In the case of vehicle model coefficient, p i ∈{v1,v2,…,v e}, where v j represents the model coefficient corresponding to the jth model. Therefore, the model coefficient corresponding to the vehicle model is p i For example, when the jth model is a small car, v j =0.2; when the jth vehicle type is a large vehicle, v j =1.5; when the jth vehicle model is an SUV, v j =0.8.

[0125] In another specific implementation, the controller calculates the basic pressure F0(t) at time t based on the second information and the third information. Therefore, the controller calculates the target pressure based on the first information, the second information and the third information. The basic pressure F0(t) at time t can be expressed as:

[0126] F0(t)=[h0+h1*x1(t)+h2*x2(t)+…+h k *x k (t)]*F0

[0127] Among them, F0(t) represents the base pressure at time t, h0, h1, h2, ... h k are coefficients, and h0+h1+h2+…+h k =1, F0 represents the standard pressure of the tire when it leaves the factory, x i (t) represents a coefficient corresponding to one of the elements in the second information or a coefficient corresponding to one of the elements in the third information.

[0128] In another specific implementation, the basic pressure F0(t) at time t may be the standard pressure of the tire when it leaves the factory, and then F0(t)=F0.

[0129] It should be understood that the above-mentioned implementation methods of the target pressure F(t) and the basic pressure F0(t) are merely examples and are not specifically limited here.

[0130] In some possible implementations, since the target pressure F(t) is calculated based on the basic pressure F0(t) of the tire, and the basic pressures of different tires are different, before calculating the target pressure based on the first information, the controller determines whether the tire is a target tire. Only when the tire is a target tire, the calculated target pressure is the current adaptation pressure of the tire. Among them, the target tire is a tire that matches the tire attributes stored in the controller. Tire attributes include tire model, standard pressure, wheel position identification number, etc. The controller determines whether the tire is a target tire in at least the following three implementations:

[0131] In a specific implementation, the controller uses the ID of the tire pressure sensor carried by the tire pressure sensor when sending the inflation / deflation request to compare with the ID of the target tire pressure sensor to determine whether the ID of the tire pressure sensor is consistent with the ID of the target tire pressure sensor, thereby determining whether the tire is the target tire. Among them, the target tire pressure sensor is the tire pressure sensor corresponding to the ID stored in the controller. When the ID of the tire pressure sensor is consistent with the ID of the target tire pressure sensor, it indicates that the controller stores the ID of the tire pressure sensor, and further indicates that the tire is the target tire, and the controller calculates the target pressure based on the first information; when the ID of the tire pressure sensor is inconsistent with the ID of the target tire pressure sensor, it indicates that the controller does not store the ID of the tire pressure sensor, and further indicates that the tire is not the target tire, and the controller sends an "information matching error" to the user.

[0132] In another specific implementation, the controller generates a tire pressure reading request and sends the tire pressure reading request to the tire pressure sensor. The tire pressure reading request includes a specified time period. After the tire pressure sensor receives the tire pressure reading request sent by the controller, it sends multiple tire pressures within the specified time period to the controller. After the controller receives multiple tire pressures within the specified time period sent by the tire pressure sensor, it determines whether there is 0 in the multiple tire pressures. When there is no 0 in the multiple tire pressures, it indicates that the tire is the target tire, and the controller calculates the target pressure based on the first information; when there is 0 in the multiple tire pressures, it indicates that the tire is not the target tire, and the controller sends an "information error" to the user, and further confirms with the user whether the tire change operation has been performed.

[0133] In another specific implementation, the controller generates a tire pressure reading request and sends the tire pressure reading request to the tire pressure sensor. After receiving the tire pressure reading request sent by the controller, the tire pressure sensor sends the ID of the tire pressure sensor and multiple tire pressures within a specified time period to the controller. After receiving the ID of the tire pressure sensor and multiple tire pressures within a specified time period sent by the tire pressure sensor, the controller determines whether the ID of the tire pressure sensor is consistent with the ID of the target tire pressure sensor, and determines whether there is 0 in the multiple tire pressures. When the ID of the tire pressure sensor is consistent with the ID of the target tire pressure sensor, and there is no 0 among the multiple tire pressures, the controller calculates the target pressure based on the first information; when the ID of the tire pressure sensor is consistent with the ID of the target tire pressure sensor, and there is 0 among the multiple tire pressures, the controller further confirms with the user whether a tire change operation has ever been performed; when the ID of the tire pressure sensor is inconsistent with the ID of the target tire pressure sensor, and there is no 0 among the multiple tire pressures, the controller sends an "information error" to the user, and further confirms with the user whether a tire change operation has ever been performed; when the ID of the target tire pressure sensor is inconsistent with the ID of the tire pressure sensor, and there is 0 among the multiple tire pressures, the controller sends an "information error" to the user, and further confirms with the user whether a tire change operation has ever been performed.

[0134] S205: The controller sends the target pressure to the tire pressure sensor.

[0135] S206: The tire pressure sensor generates a start instruction when receiving the target pressure, and sends the start instruction to the inflation / deflation device.

[0136] The start command can be Figure 1 The start command 16 in the tire pressure control system 10 in FIG.

[0137] In some possible implementations, the tire pressure sensor generates a start instruction including at least the following two implementations:

[0138] In a specific implementation, when the inflation / deflation request received by the tire pressure sensor includes the first request information, that is, corresponding to the inflation / deflation request including the first request information in the above step S201, the tire pressure sensor collects the tire pressure of the tire when receiving the target pressure, and records the collected tire pressure as the initial pressure of the tire. Subsequently, the tire pressure sensor compares the target pressure with the initial pressure. When the target pressure is greater than the initial pressure, the start instruction generated by the tire pressure sensor is an inflation start instruction; when the target pressure is less than the initial pressure, the start instruction generated by the tire pressure sensor is a deflation start instruction.

[0139] In another specific implementation, when the inflation / deflation request received by the tire pressure sensor includes the second request information and the inflation information, that is, corresponding to the inflation / deflation request including the second request information and the inflation information in step S201, the start instruction generated by the tire pressure sensor is an inflation start instruction. When the inflation / deflation request received by the tire pressure sensor includes the second request information and the deflation information, that is, corresponding to the inflation / deflation request including the second request information and the deflation information in step S201, the start instruction generated by the tire pressure sensor is a deflation start instruction.

[0140] S207: The inflation / deflation device performs an inflation operation or a deflation operation on the tire based on the start instruction.

[0141] When the start command is an inflation start command, the inflation / deflation device performs an inflation operation on the tire. When the start command is a deflation start command, the inflation / deflation device performs a deflation operation on the tire.

[0142] S208: The tire pressure sensor determines whether the tire pressure is equal to the target pressure.

[0143] In some possible implementations, since the inflation / deflation device inflates or deflates the tire based on the start instruction, the tire pressure changes over time. During the inflation / deflation process, the tire pressure sensor monitors and collects the tire pressure in real time, compares the tire pressure with the target pressure, and determines whether the tire pressure is equal to the target pressure. If the tire pressure is equal to the target pressure, it indicates that the inflation or deflation operation can be terminated; if the tire pressure is not equal to the target pressure, it indicates that the inflation or deflation operation can continue.

[0144] S209: When the tire pressure is equal to the target pressure, the tire pressure sensor generates an end instruction and sends the end instruction to the inflation / deflation device so that the inflation / deflation device ends the inflation or deflation operation on the tire.

[0145] The end instruction can be Figure 1 The end instruction 17 in the tire pressure control system 10 in FIG.

[0146] In some possible implementations, after receiving the end instruction, the inflation / deflation device ends the tire inflation or deflation operation and prompts the user through a display interface that the inflation / deflation is completed.

[0147] In a specific implementation, the inflation / deflation device receives an end instruction and a target pressure sent by the tire pressure sensor, and the inflation / deflation device prompts the user through a display interface that inflation / deflation is complete and displays the target pressure.

[0148] In another specific implementation, the tire pressure sensor also sends an end instruction to the controller. After receiving the end instruction, the controller controls voice, speakers, lights, etc. to prompt the user that the inflation / deflation is completed.

[0149] In summary, this technical solution calculates the target pressure based on information such as mileage, tire load, and tread depth. The tire pressure sensor notifies the inflation / deflation device to perform inflation or deflation based on the target pressure, and the tire pressure sensor determines in real time whether to end the inflation or deflation operation. Therefore, while ensuring that the target pressure is the current adaptation pressure of the tire, the accuracy of inflation / deflation is improved, and the effect of controlling the tire pressure to be consistent with the target pressure is achieved. The automation of the inflation / deflation process is also realized, and there is no need for the user to intervene in the inflation or deflation operation, which effectively improves the convenience of the inflation or deflation operation. Furthermore, this technical solution can also calculate the target pressure based on information such as driving weather, driving temperature, driving road conditions, driving experience, vehicle model, and tire model, that is, comprehensively considering the current adaptation pressure of the tire from multiple dimensions, and therefore, it can effectively improve the user's driving experience and comfort. On the other hand, in the present technical solution, the inflation / deflation device directly exchanges information with the tire pressure sensor, and the tire pressure sensor directly exchanges information with the controller, that is, the inflation / deflation process interacts two by two, with few interaction nodes, thereby effectively improving the efficiency of the inflation operation or deflation operation and improving the intelligence level of the inflation / deflation process.
