Description

Technical Field

[0001] This invention relates to the field of automotive technology, and more specifically, to a method and system for matching and learning tire pressure sensors for a vehicle controller. Background Technology

[0002] Current tire pressure monitoring systems on the market match the tire pressure sensor IDs and locations within car tires using several methods. First, they use specialized, complex equipment to read the tire pressure sensor ID information, then store it in the controller via configuration writing. Second, they operate different wheels at different speeds, identifying the tire pressure sensor's location by wheel speed and then memorizing the tire pressure readings. These methods involve complex techniques and devices, resulting in significant software development difficulties and increased costs associated with tire pressure sensor matching and learning. Furthermore, learning efficiency is limited by the operator's skill level, and it causes considerable inconvenience when users need to re-match and learn the tire pressure sensor IDs after changing tires. Summary of the Invention

[0003] This invention provides a method and system for matching and learning tire pressure sensors for a vehicle controller, in order to overcome at least one technical problem existing in the prior art.

[0004] On one hand, the present invention provides a method for matching and learning tire pressure sensors for a vehicle controller, comprising: The design includes 31 routines for tire pressure learning, which include a preset tire learning sequence. The first tire set in the tire pressure learning routine 31 is used as the current tire; Send a command to the controller to start the tire pressure learning routine 31 and begin timing; The tire pressure sensor is activated by the tire pressure sensor activation device. The controller sends high-frequency data signals learned from the tire pressure sensors; the high-frequency data signals include tire pressure sensor ID information. The high-frequency data signal is verified. When tire pressure data in learning mode is received, the tire pressure sensor ID information is stored and the timer is cleared. Determine if the current tire is the last tire. If not, set the next tire as the current tire and return to step 31 of the tire pressure learning routine. If it is, the program ends.

[0005] Optionally, after initiating the tire pressure learning 31 routine, it also includes: The controller determines whether the current tire's tire pressure sensor ID information exists in the controller by using the value of the stored tire pressure sensor ID information bit. If it does, the current tire learning process is exited, a message indicating that the current tire learning process failed is displayed, and the process jumps to the step of determining whether the current tire is the last tire. If it does not, the process jumps to activating the current tire's tire pressure sensor.

[0006] Optionally, before verifying the high-frequency data signal, the method further includes: Determine whether the controller has received a high-frequency data signal. If no high-frequency data signal is received, determine whether a timeout has occurred. If no timeout has occurred, return to the step of activating the tire pressure sensor of the current tire; if a timeout has occurred, return to the step of starting tire pressure learning routine 31.

[0007] Optionally, the high-frequency data signal is verified, including: Verify whether the high-frequency data signal received by the controller is valid data; When valid data is received, verify whether the high-frequency data signal received by the controller is the tire pressure data in learning mode.

[0008] Optionally, verifying whether the high-frequency data signal received by the controller is a valid number involves: The high-frequency data signal is verified based on the data integrity verification information. If the verification passes, it indicates that the received high-frequency data signal is valid data; if the verification fails, it indicates that the received high-frequency data signal is not valid data, and the process returns to the step of activating the tire pressure sensor of the current tire.

[0009] Optionally, verify whether the high-frequency data signal received by the controller is tire pressure data in learning mode, specifically: Determine whether the data value of the tire pressure sensor status information bit is a predetermined value. If yes, it indicates that the high-frequency data signal is tire pressure data in learning mode; if not, it indicates that the high-frequency data signal is not tire pressure data in learning mode, and return to the step of activating the tire pressure sensor of the current tire.

[0010] Optionally, after storing the tire pressure sensor ID information, the system may also include a message indicating that the current tire has been successfully learned.

[0011] Optionally, when it is necessary to delete the tire pressure sensor ID information of a specific tire: Design 31 procedures for tire pressure reduction; Send a command to the controller to start the tire pressure deleting procedure 31; Check if the tire pressure sensor ID information for the specified tire exists in the controller. If it exists, delete the stored data and indicate successful deletion; if it does not exist, exit the deletion process and indicate deletion failure.

[0012] Optionally, when it is necessary to check learning progress: The learning schedule is designed with 31 routines. Send a command to the controller to start the learning progress routine 31; Check whether the controller has saved the tire pressure sensor ID information of all tires. If so, return the learning completion status and all tire pressure sensor ID information. If not, return the learning incomplete status and the tire pressure sensor ID information that has been learned.

[0013] On the other hand, the present invention also provides a system for matching and learning tire pressure sensors for a vehicle controller, comprising: The first design module is used to design 31 routines for tire pressure learning, which include a preset tire learning sequence. The setting module is used to set the first tire in the tire pressure learning routine 31 as the current tire. The first sending module is used to send a command to the controller to start the tire pressure learning routine 31 and start timing; Tire pressure sensor activation device, used to activate the tire pressure sensor of the current tire; The second transmitting module is used to send high-frequency data signals learned by the tire pressure sensor to the controller; the high-frequency data signals include tire pressure sensor ID information. The verification module is used to verify the high-frequency data signal. When the tire pressure data in the learning mode is received, the tire pressure sensor ID information is stored and the timer is cleared. The judgment module is used to determine whether the current tire is the last tire. If not, the next tire is set as the current tire, and the program returns to step 31 of the tire pressure learning routine. If it is, the program ends.

[0014] The innovative aspects of this invention include: In this embodiment, the tire pressure sensor is activated using a simple handheld device. After activation, the tire pressure sensor sends high-frequency signal data including ID information. After receiving the high-frequency data, the controller judges the data validity and learning status, and realizes the matching and learning of the ID data of the tire pressure sensor. In this way, if the learning is wrong or the wheel is replaced, the learning can be easily and cost-effectively relearned. Moreover, when the whole vehicle is off the production line and powered on again, the tire pressure can be learned for the first time at an even lower cost, which is one of the innovations of this embodiment.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] It should be noted that the terms "comprising" and "having," and any variations thereof, in the embodiments and drawings of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0019] This invention discloses a method and system for matching and learning tire pressure sensors for a vehicle controller. These will be described in detail below.

[0020] Figure 1 This is a flowchart of a method for matching and learning tire pressure sensors for a vehicle controller, provided in an embodiment of the present invention. Please refer to it. Figure 1 The method for matching and learning tire pressure sensors for a vehicle controller, provided in this embodiment of the invention, includes: Step 1: Design 31 tire pressure learning routines, which include a preset tire learning sequence; Step 2: Set the first tire set in the tire pressure learning routine 31 as the current tire; Step 3: Send a command to the controller to start the tire pressure learning routine 31 and start timing; Step 4: Activate the tire pressure sensor of the current tire via the tire pressure sensor activation device; Step 5: Send the high-frequency data signal learned by the tire pressure sensor to the controller; the high-frequency data signal includes the tire pressure sensor ID information; Step 6: Verify the high-frequency data signal. When tire pressure data from the learning mode is received, store the tire pressure sensor ID information and clear the timer. Step 7: Determine if the current tire is the last tire. If not, set the next tire as the current tire and return to the "Start Tire Pressure Learning 31" routine step; if yes, the program ends.

[0021] For details, please refer to Figure 1 The method for matching and learning tire pressure sensors for a vehicle controller provided in this embodiment of the invention first designs a tire pressure learning routine (31 routines) in step 1. To ensure that all tires are learned, this invention sets a learning order for the tires that need to be learned in the tire pressure learning routines, ensuring that learning is performed only after all wheels are installed on the vehicle, thus avoiding learning errors caused by incorrect sorting. When learning the tire pressure ID of the vehicle, in step 2, according to the order set in step 1, the first tire set in the tire pressure learning routines is taken as the current tire, and then each tire is learned sequentially, avoiding any omissions.

[0022] After the setup is complete, in step 3, you can send a command to start the controller's tire pressure learning routine service 31 and begin timing. In this invention, the command protocol is Unified Diagnostic Services (UDS).

[0023] At the start of the learning process, the tire pressure sensor is activated first in step 4. In this invention, the tire pressure sensor of the current tire is activated by hand-held activation of the tire pressure sensor device. After the tire pressure sensor is activated, in step 5, it automatically sends a high-frequency data signal for tire pressure sensor learning to the controller. This high-frequency data signal includes at least the tire pressure sensor ID information.

[0024] After the tire pressure sensor sends the high-frequency data signal it has learned, the controller waits to receive the high-frequency data signal. It then verifies the high-frequency data signal in step 6, first checking whether the received high-frequency data signal is valid.

[0025] The high-frequency data signal also includes data integrity verification information and tire pressure sensor status information. In this embodiment, the high-frequency data signal is verified by the data integrity verification information. If the verification passes, it means that the received high-frequency data signal is valid data; otherwise, it means that the received high-frequency data signal is not valid data.

[0026] If the received high-frequency data signal is not valid, return to step 4, reactivate the tire pressure sensor of the current tire, and relearn the current tire. Conversely, if it is valid data, determine whether the high-frequency data signal received by the controller is tire pressure data in learning mode. If it is not in learning mode, return to step 4, reactivate the tire pressure sensor of the current tire, and relearn the current tire; otherwise, if it is in learning mode, it indicates that the learning was successful, the tire pressure sensor ID information in the high-frequency data signal is stored, and the timer is cleared.

[0027] In this embodiment, the high-frequency data signal is determined to be tire pressure data in learning mode by the data value of the tire pressure sensor status information bit. For example, when the data value of the tire pressure sensor status information bit is a predetermined value, it indicates that the high-frequency data signal is tire pressure data in learning mode; otherwise, it indicates that the high-frequency data signal is not tire pressure data in learning mode.

[0028] Once a tire pressure sensor has been successfully learned, the user can be notified by honking. To help users distinguish between successful learning, failed learning, and no learning required, different honking frequencies can be set; for example, one honk for successful learning, two honks for failed learning, and three honks for no learning required. This way, success can be immediately recognized after each learning cycle, without waiting for the vehicle to move.

[0029] Typically, a vehicle has multiple tires. Therefore, after learning the tire for each tire, it's necessary to determine if there are any tires yet to be learned. This invention, in step 7, determines if the current tire is the last tire. If it's not the last tire, the next tire is selected as the current tire, and the process returns to step 3 to begin learning the next tire. Conversely, if it is the last tire, it means all tires have been learned, and the program ends.

[0030] The present invention provides a method for matching and learning tire pressure sensors for vehicle controllers. This method uses a simple handheld device to activate the tire pressure sensor. After activation, the tire pressure sensor sends high-frequency signal data including ID information. Upon receiving the high-frequency data, the controller judges the data validity and learning status, thus achieving matching and learning of the tire pressure sensor's ID data. In this way, if a learning error occurs or the wheel is replaced, relearning can be performed easily and at low cost. Furthermore, when the vehicle is re-energized after production, initial tire pressure learning can be performed at an even lower cost.

[0031] Optionally, Figure 2 Please refer to another flowchart of the method for matching and learning tire pressure sensors for a vehicle controller, as provided in the embodiments of the invention. Figure 2 After starting the tire pressure learning routine 31, it also includes: Step 04, by using the value of the tire pressure sensor ID information storage bit, to determine whether there is tire pressure sensor ID information of the current tire in the controller. If there is, exit the current tire learning, prompt that the current tire learning has failed, and jump to the step of determining whether the current tire is the last tire; if not, jump to activate the tire pressure sensor of the current tire.

[0032] Specifically, if the tire pressure sensor ID information for the current tire exists in the controller, relearning is not required. Therefore, please refer to... Figure 2 Before the controller learns the tire pressure ID, step 04 is used to check whether the controller has the tire pressure sensor ID information for the current tire.

[0033] Before learning the tire pressure sensor, the storage bit for the tire pressure sensor ID information in the controller is usually at a default value. Therefore, the existence of the tire pressure sensor ID information for the current tire can be determined by checking this storage bit. For example, if the storage bit for the tire pressure sensor ID information is at the default value, it means that the controller does not have the tire pressure sensor ID information for the current tire; conversely, if it is not at the default value, it means that the controller has the tire pressure sensor ID information for the current tire.

[0034] If the tire pressure sensor ID information of the current tire is available, there is no need to learn the current tire. Therefore, jump to step 7 to determine if the current tire is the last tire. If it is not the last tire, the next tire is taken as the current tire, and return to step 3. The tire pressure learning routine service of the controller is started by sending a command to learn and determine the current tire. Otherwise, if it is the last tire, it means that all tires have been learned and the program ends.

[0035] If the controller does not have the tire pressure sensor ID data for the current tire, it needs to learn the current tire's sensor data and then execute the subsequent steps sequentially. It should be noted that when learning the current tire is not required, the user can be promptly notified of the learning status via a horn, allowing the user to accurately determine the location of the next tire sensor to be activated.

[0036] Optionally, Figure 3 Please refer to another flowchart of the method for matching and learning tire pressure sensors for a vehicle controller provided in the embodiments of the invention. Figure 3 Before verifying the high-frequency data signal, the process also includes: Step 06, determining whether the controller has received the high-frequency data signal. If the high-frequency data signal is not received, it determines whether a timeout has occurred. If no timeout has occurred, it returns to the step of activating the tire pressure sensor of the current tire; if a timeout has occurred, it returns to the step of starting the tire pressure learning routine 31.

[0037] Specifically, the controller can only perform tire pressure sensor ID learning after receiving a high-frequency data signal. Therefore, please refer to... Figure 3 In this embodiment, before performing the verification, step 06 is used to determine whether the controller has received a high-frequency data signal.

[0038] If no high-frequency data signal is received, the system further checks for timeout. Timeout refers to whether the time since the start of the timing has exceeded a predetermined time. The predetermined time can be set according to the specific system being used and is not specifically limited here. If there is no timeout, the system returns to step 4, reactivates the tire pressure sensor of the current tire, and relearns the current tire. Conversely, if a timeout occurs, the system exits the current learning process, returns to step 3, and sends a command to the controller again to start the tire pressure learning routine 31, relearning the current tire.

[0039] Optionally, Figure 4 Please refer to the flowchart for deleting tire pressure sensor ID information provided in this embodiment of the invention. Figure 4When it is necessary to delete the tire pressure sensor ID information: Step 11, design the tire pressure deletion routine 31; Step 12, send a command to the controller to start the tire pressure deletion routine 31; Step 13, check whether the tire pressure sensor ID information of the specified tire exists in the controller. If it exists, delete the stored data and prompt that the deletion was successful; if it does not exist, exit the deletion process and prompt that the deletion failed.

[0040] Specifically, for controllers that have already learned but need to relearn, or controllers that have memorized tire pressure sensor IDs with incorrect locations, this invention designs a process for deleting tire pressure sensor ID information. Please refer to... Figure 4 When it is necessary to delete tire pressure sensor ID information, the first step is to design a tire pressure deletion routine (31 routines) via step 11. Then, via step 12, a command is sent to the controller to start the tire pressure deletion routine (31 routines). In this invention, the protocol for the command is the Unified Diagnostic Service (UDS). After receiving the above command, the controller begins to execute the routine (31 routines) for deleting tire pressure ID information. When executing this program, only the tire pressure sensor ID information stored in the controller needs to be deleted. Therefore, via step 13, it is checked whether the tire pressure sensor ID information of the specified tire exists in the controller. If it exists, the stored data is deleted, and a horn beep (e.g., two horn beeps) is used to indicate successful deletion; if it does not exist, the deletion process is exited, and a horn beep (e.g., three horn beeps) is used to indicate deletion failure.

[0041] Optionally, Figure 5 Please refer to the flowchart provided in this embodiment of the invention for checking learning progress. Figure 5 When it is necessary to check the learning progress: Step 21, design the learning progress routine 31; Step 22, send a command to the controller to start the learning progress routine 31; Step 23, check whether the controller has saved the tire pressure sensor ID information of all tires. If so, it will report the learning completion status and all tire pressure sensor ID information; if not, it will report the learning incomplete status and the tire pressure sensor ID information that has been learned.

[0042] Specifically, to facilitate the checking of the learning progress of the vehicle's tire pressure sensor ID matching, this invention designs a process for checking the learning progress. Please refer to... Figure 5When it is necessary to check the learning progress, firstly, in step 21, a learning progress routine 31 is designed. Then, in step 22, a command is sent to the controller to start the learning progress routine 31. In this invention, the protocol for the command is the Unified Diagnostic Service (UDS). After receiving the above command, the controller executes the learning progress routine 31 in step 23, checking whether the controller has saved the tire pressure sensor ID information of all tires. If so, it indicates that the learning of all tires is complete, and the controller returns the learning completion status and all tire pressure sensor ID information. If not, it indicates that there are still tire pressure sensors that have not been learned. In this case, the controller returns the learning incomplete status and simultaneously sends the tire pressure sensor ID information that has been learned.

[0043] Based on the same inventive concept, the present invention also provides a system for matching and learning tire pressure sensors for a vehicle controller. Figure 6 This is a schematic diagram of a system for matching and learning tire pressure sensors for a vehicle controller, provided in an embodiment of the present invention. Please refer to... Figure 6 The system 100 for matching and learning tire pressure sensors for vehicle controllers provided in this embodiment of the invention includes: The first design module is used to design 31 routines for tire pressure learning, which include a preset tire learning sequence. The setting module is used to set the first tire in the tire pressure learning 31 routines as the current tire. The first sending module is used to send a command to the controller to start the tire pressure learning routine 31 and start the timing; Tire pressure sensor activation device, used to activate the tire pressure sensor of the current tire; The second transmitting module is used to send high-frequency data signals learned by the tire pressure sensor to the controller; the high-frequency data signals include tire pressure sensor ID information; The verification module is used to verify high-frequency data signals. When it receives tire pressure data from the learning mode, it stores the tire pressure sensor ID information and clears the timer. The first judgment module is used to determine whether the current tire is the last tire. If not, the next tire is set as the current tire, and the program returns to step 31 of the tire pressure learning routine. If it is, the program ends.

[0044] For details, please refer to Figure 6The system 100 for matching and learning tire pressure sensors with a vehicle controller, provided in this embodiment of the invention, firstly designs 31 routines for tire pressure learning through a first design module. To ensure that all tires are learned, the invention sets a learning order for the tires that need to be learned in the 31 routines, ensuring that learning is performed only after all wheels are installed on the vehicle, thus avoiding learning errors caused by incorrect sorting. When learning tire pressure IDs for the vehicle, the setting module, according to the order set in the 31 routines, takes the first tire set in the 31 routines as the current tire, and then learns them one by one in sequence, thus avoiding omissions.

[0045] Once the setup is complete, the first sending module can be used to send commands to activate the controller's tire pressure learning routine service (Routine 31) and start timing. In this invention, the command protocol is Unified Diagnostic Services (UDS).

[0046] To begin learning, the tire pressure sensor of the current tire is activated by hand-holding the tire pressure sensor activation device. After the tire pressure sensor is activated, the second transmitting module controls the tire pressure sensor to automatically send high-frequency data signals for tire pressure sensor learning to the controller. These high-frequency data signals include at least the tire pressure sensor ID information.

[0047] After the tire pressure sensor sends its learned high-frequency data signal, the controller waits to receive it. The controller then verifies the high-frequency data signal using a verification module. During verification, the first step is to check whether the received high-frequency data signal is valid.

[0048] The high-frequency data signal also includes data integrity verification information and tire pressure sensor status information. In this embodiment, the high-frequency data signal is verified using the data integrity verification information. If the verification passes, it indicates that the received high-frequency data signal is valid; otherwise, it indicates that the received high-frequency data signal is not valid.

[0049] If the received high-frequency data signal is not valid, the process returns to the step of reactivating the tire pressure sensor of the current tire and relearning the current tire. Conversely, if the data is valid, the controller checks whether the high-frequency data signal received is tire pressure data in learning mode. If it is not in learning mode, the process returns to the step of reactivating the tire pressure sensor of the current tire and relearning the current tire; otherwise, if it is in learning mode, the learning is successful, the tire pressure sensor ID information in the high-frequency data signal is stored, and the timer is cleared.

[0050] In this embodiment, the high-frequency data signal is determined to be tire pressure data in learning mode by the data value of the tire pressure sensor status information bit. For example, when the data value of the tire pressure sensor status information bit is a predetermined value, it indicates that the high-frequency data signal is tire pressure data in learning mode; otherwise, it indicates that the high-frequency data signal is not tire pressure data in learning mode.

[0051] Once a tire pressure sensor has been successfully learned, the user can be notified by honking. To help users distinguish between successful learning, failed learning, and no learning required, different honking frequencies can be set; for example, one honk for successful learning, two honks for failed learning, and three honks for no learning required. This way, success can be immediately recognized after each learning cycle, without waiting for the vehicle to move.

[0052] Typically, a vehicle has multiple tires. Therefore, after each tire has been learned, it is necessary to determine if there are any tires that have not yet been learned. This invention uses a first judgment module to determine if the current tire is the last tire. If it is not the last tire, the next tire is designated as the current tire, and a new command is sent to the controller to start the tire pressure learning routine 31, beginning the learning process for the next tire. Conversely, if it is the last tire, it indicates that all tires have been learned, and the program ends.

[0053] The present invention provides a system for matching and learning tire pressure sensors for vehicle controllers. This system uses a simple handheld device to activate the tire pressure sensor. After activation, the tire pressure sensor sends high-frequency signal data including ID information. Upon receiving this high-frequency data, the controller judges the data validity and learning status, thus achieving matching and learning of the tire pressure sensor's ID data. In this way, if a learning error occurs or the wheel is replaced, relearning can be performed easily and at low cost. Furthermore, when the vehicle is re-energized after production, initial tire pressure learning can be performed at an even lower cost.

[0054] Optionally, Figure 7 This is another structural schematic diagram of the system for matching and learning tire pressure sensors for a vehicle controller, provided in an embodiment of the present invention. Please refer to... Figure 7 When it is necessary to delete the tire pressure sensor ID information, the system also includes: a second design module for designing the tire pressure deletion routine; a third sending module for sending a command to the controller to start the tire pressure deletion routine; and a first checking module for checking whether the tire pressure sensor ID information of the specified tire exists in the controller. If it exists, the stored data is deleted and a message indicating successful deletion is displayed. If it does not exist, the deletion process is exited and a message indicating deletion failure is displayed.

[0055] Specifically, for controllers that have already learned but need to relearn, or controllers that have memorized tire pressure sensor IDs with incorrect locations, this invention designs a process for deleting tire pressure sensor ID information. Please refer to... Figure 7 When it is necessary to delete tire pressure sensor ID information, the second design module first designs a 31-step routine for deleting tire pressure sensor IDs. Then, the third sending module sends a command to the controller to activate the 31-step routine. In this invention, the command protocol is the Unified Diagnostic Service (UDS). After receiving the command, the controller begins executing the 31-step routine for deleting tire pressure sensor ID information. During this execution, only the tire pressure sensor ID information stored in the controller needs to be deleted. Therefore, the first checking module checks whether the tire pressure sensor ID information for the specified tire exists in the controller. If it exists, the stored data is deleted, and a horn beep (e.g., two horn beeps) indicates successful deletion; if it does not exist, the deletion process exits, and a horn beep (e.g., three horn beeps) indicates deletion failure.

Please refer to... Figure 8 When it is necessary to check the learning progress, it also includes: a third design module, used to design the learning progress routine 31; a fourth sending module, used to send a command to the controller to start the learning progress routine 31; and a second checking module, used to check whether the controller has saved the tire pressure sensor ID information of all tires. If so, it will return the learning completion status and all tire pressure sensor ID information; if not, it will return the learning incomplete status and the tire pressure sensor ID information that has been learned.

[0057] Specifically, to facilitate the checking of the learning progress of the vehicle's tire pressure sensor ID matching, this invention designs a process for checking the learning progress. Please refer to... Figure 8 When it is necessary to check the learning progress, the learning progress routine 31 is first designed through the third design module. Then, the fourth sending module sends a command to the controller to start the learning progress routine 31. In this invention, the protocol of the command is the Unified Diagnostic Service (UDS). After receiving the above command, the controller executes the learning progress routine 31 through the second checking module to check whether the tire pressure sensor ID information of all tires is stored in the controller. If so, it means that the learning of all tires is completed, and the controller returns the learning completion status and all tire pressure sensor ID information. If not, it means that there are still tire pressure sensors that have not been learned. In this case, the controller returns the learning incomplete status and sends the tire pressure sensor ID information that has been learned.
