Description

Tire pressure sensor configuration method Technical Field

[0001] The present invention relates to the technical field of tire pressure monitoring, and in particular to a tire pressure sensor configuration method. Background Art

[0002] Currently, the interaction between tire pressure sensors and vehicle ECUs is one-way communication. The tire pressure sensors can only actively send 433M or 315M RF tire pressure information, and the vehicle ECU can only passively receive the tire pressure information sent by the tire pressure sensors. In addition, the operating modes and main operating parameters of tire pressure sensors applicable to different vehicle models will vary. The configuration parameter data of tire pressure sensors in existing technologies are all solidified in the firmware code of the TPMS (Tire Pressure Monitoring System) transmitter. Since the tire pressure sensor is manufactured using glue injection or laser welding, the code cannot be changed after it is completed. This leads to the following problems:

[0003] 1. Currently, different models are mixed together on the same production line in car factories. The operating parameters of tire pressure sensors installed on different models vary. This results in frequent switching of tire pressure equipment configuration information during vehicle calibration. This reduces assembly efficiency due to the switching of vehicle configurations.

[0004] 2. According to traditional methods, the working mode or working parameters of the new project have changed, requiring the redesign of a new tire pressure sensor product and the introduction of a new material. This will extend the corresponding development and testing cycle and increase development costs.

[0005] 3. When replacing the tire pressure sensor after sales, you need to search the database according to the car model and year to find the appropriate replacement part. Special tools are also required to complete the after-sales matching work. Non-professionals cannot complete the corresponding operation.

[0006] Summary of the Invention

[0007] In response to the above-mentioned problems in the prior art, the present invention proposes a tire pressure sensor configuration method to achieve effective configuration of tire pressure sensors, which is applicable to different vehicle models and can effectively reduce product development and design costs and shorten the development cycle.

[0013] According to one embodiment of the present invention, the vehicle ECU activates the working mode of the tire pressure sensor using a low-frequency instruction, where the low-frequency instruction includes a low-frequency carrier wake-up format and a data wake-up format.

[0015] The process of the vehicle ECU configuring the tire pressure sensor according to pre-stored configuration parameters includes: the vehicle ECU reading the current configuration state of the tire pressure sensor and configuring the parameters of the tire pressure sensor according to the current configuration state.

[0016] According to one embodiment of the present invention, if the current configuration state of the tire pressure sensor is unconfigured, the vehicle ECU sends pre-stored configuration parameters to the tire pressure sensor and saves them to the current configuration parameter module.

[0017] According to one embodiment of the present invention, if the current configuration state of the tire pressure sensor is configured, the tire pressure sensor sends the configuration parameters stored in the current configuration parameter module to the vehicle ECU for comparison with the pre-stored configuration parameters;

[0018] If there is a difference between the two, the vehicle ECU sends the configuration parameters to the tire pressure sensor and saves them to the current configuration parameter module;

[0019] If the two are the same, the configuration parameters of the current configuration parameter module of the tire pressure sensor are retained.

[0020] According to one embodiment of the present invention, if the configuration parameters of the current configuration parameter module of the tire pressure sensor are updated, the tire pressure sensor operates based on the updated configuration parameters and confirms the configuration completion to the vehicle ECU.

[0021] According to one embodiment of the present invention, the tire pressure sensor is switchable in one of a plurality of operating modes;

[0022] In the stationary mode, determining whether a flameout monitoring function is enabled, and if so, setting a duration of the flameout monitoring function; and entering the operating mode if the centripetal acceleration value of the tire is detected to be greater than or equal to a first threshold;

[0023] In the operating mode, if the centripetal acceleration value of the tire is detected to be greater than or equal to a second threshold, the operating state is maintained; if the centripetal acceleration value of the tire is detected to be less than a third threshold, the stationary mode is entered; if the change in air pressure of the tire between the current moment and the previous moment is detected to exceed a fourth threshold, the pressure change mode is entered;

[0024] In the pressure change mode, if the tire air pressure change is less than a fifth threshold value within a first set time period, the pressure change mode is exited.

[0025] According to one embodiment of the present invention, the working mode further includes a sleep mode, a positioning mode and a delay mode;

[0026] If the delay mode exists, then in the operating mode, if it is detected that the centripetal acceleration value of the tire is less than a third threshold, the delay mode is entered;

[0027] In the dormant mode, if it is detected that the tire pressure value of the tire is greater than or equal to a sixth threshold, entering the stationary mode;

[0028] In the positioning mode, selecting the positioning mode duration and positioning function type;

[0029] In the delay mode, if the centripetal acceleration value of the tire is detected to be greater than or equal to the seventh threshold value within the second set time period, the system returns to the previous working mode; otherwise, the system enters the static mode at the end of the second set time period.

[0042] Figure 1 shows a flowchart of a tire pressure sensor configuration method according to one embodiment of the present invention. As shown in the figure, the present invention provides a tire pressure sensor configuration method. The tire pressure sensor is a configurable sensor that can receive configuration parameters from the vehicle ECU, store them, and operate based on them. The configuration method includes:

[0043] Establish communication between vehicle ECU and tire pressure sensor;

[0044] The vehicle ECU configures the tire pressure sensor based on pre-stored configuration parameters. As will be readily understood, different types of vehicles have different configuration requirements for tire pressure sensors. Because the tire pressure sensor provided by the present invention is configurable, different types of vehicles can pre-store configuration parameters matching their vehicle type in their ECUs, allowing them to configure the parameters of the tire pressure sensor installed on the vehicle.

[0045] Preferably, the configuration parameters pre-stored in the vehicle ECU include multiple operating modes applicable to the tire pressure sensor, and configuration parameter information corresponding to each operating mode, the configuration parameter information including sampling period parameters, broadcast transmission parameters and operating parameters;

[0046] The multiple working modes include at least a static mode, a running mode and a pressure change mode.

[0047] Preferably, in each operating mode, the tire pressure sensor periodically samples information such as the tire pressure, ambient temperature, centripetal acceleration, and battery voltage, and then transmits this information via BLE broadcast data. The sampling period parameters include at least sampling period data for tire pressure, temperature, acceleration, and battery (corresponding to the aforementioned tire pressure, ambient temperature, centripetal acceleration, and battery voltage, respectively). The broadcast transmission parameters include at least the broadcast period, broadcast interval, and broadcast frame number. The operating parameters include at least multiple different operating parameter values.

[0048] Refer to Table 1, including A2 static mode, A4 operating mode and A5 pressure change mode. In each working mode, there is corresponding configuration parameter information.

[0049] Table 1 Tire pressure sensor working mode and parameter configuration table

[0050] Preferably, the vehicle ECU activates the tire pressure sensor's operating mode using low-frequency commands. These low-frequency commands include a low-frequency carrier wake-up format and a data wake-up format, as shown in Table 2. Specifically, the tire pressure sensor supports 125kHz low-frequency command activation for offline matching of the tire pressure sensor. Traditional tire pressure sensors only support customer-specific low-frequency commands, which are fixed in their firmware and cannot be modified. Because the present invention utilizes a configurable tire pressure sensor, enabling bidirectional communication between the vehicle ECU and the tire pressure sensor, low-frequency commands can be added to the tire pressure sensor through configuration, enabling the sensor to support both the low-frequency carrier wake-up format and the data wake-up format.

[0051] Table 2 Low-frequency instruction configuration parameters

[0052] Preferably, the tire pressure sensor includes a current configuration parameter module and a current configuration status module. The current configuration parameter module is used to store the configuration parameters received by the tire pressure sensor, while the current configuration status module is used to identify the current configuration status. The current configuration status can be used to characterize the vehicle type, indicating whether the tire pressure sensor was previously configured for a certain type of vehicle or not. The current configuration parameter module and the current configuration status module can be understood as two memories provided on the tire pressure sensor: the current configuration parameter module is a read / write memory, while the current configuration status module is a read-only memory.

[0053] The process of the vehicle ECU configuring the tire pressure sensor according to the pre-stored configuration parameters includes: the vehicle ECU reading the current configuration state of the tire pressure sensor and configuring the parameters of the tire pressure sensor according to the current configuration state.

[0054] Preferably, if the current configuration state of the tire pressure sensor is not configured, the vehicle ECU sends the pre-stored configuration parameters to the tire pressure sensor and saves them to the current configuration parameter module. The current configuration state is not configured, indicating that the tire pressure sensor has not been configured by the vehicle before.

[0055] Preferably, if the current configuration state of the tire pressure sensor is configured, the tire pressure sensor sends the configuration parameters stored in the current configuration parameter module to the vehicle ECU for comparison with the pre-stored configuration parameters;

[0056] If there is a discrepancy between the two, the vehicle ECU sends the configuration parameters to the tire pressure sensor and saves them to the current configuration parameter module. This indicates that the tire pressure sensor was previously configured for a different vehicle type than the current one, or that the sensor was configured for the same vehicle type but with different operating modes and configuration parameter information.

[0057] If the two are the same, the configuration parameters of the current configuration parameter module of the tire pressure sensor are retained. This situation indicates that the vehicle type previously configured for the tire pressure sensor is consistent with the currently configured vehicle type, and the specific working mode type and configuration parameter information are exactly the same.

[0058] Preferably, if the configuration parameters of the current configuration parameter module of the tire pressure sensor are updated, the tire pressure sensor operates based on the updated configuration parameters and confirms to the vehicle ECU that the configuration is complete.

[0059] Preferably, the tire pressure sensor is switchable to one of a plurality of operating modes;

[0060] In the stationary mode, determining whether a flameout monitoring function exists and, if so, setting a duration for the flameout monitoring function; and entering the operating mode if the centripetal acceleration value of the tire is detected to be greater than or equal to a first threshold.

[0061] In the running mode, if the centripetal acceleration value of the tire is detected to be greater than or equal to the second threshold, the running state is maintained; if the centripetal acceleration value of the tire is detected to be less than the third threshold, the stationary mode is entered; if the change in tire pressure between the current moment and the previous moment is detected to exceed the fourth threshold, the pressure change mode is entered;

[0062] In the pressure change mode, if the tire air pressure change is less than a fifth threshold value within a first set time period, the pressure change mode is exited.

[0063] It should be noted that to ensure the basic functionality of the tire pressure sensor, the stationary mode, operating mode, and pressure change mode are the basic operating modes and are generally required during configuration. However, the corresponding acquisition cycle parameters, broadcast parameters, and operating parameters for these operating modes are still configurable. In other words, even if the tire pressure sensor requires the same operating mode on different vehicle types, different configuration parameters may still be required for the same operating mode.

[0064] Preferably, the operating modes of the tire pressure sensor also include a sleep mode, a positioning mode and a delay mode;

[0065] If the delay mode exists, then in the running mode, if the centripetal acceleration value of the tire is detected to be less than the third threshold, the delay mode is entered;

[0066] In the dormant mode, if the tire pressure is detected to be greater than or equal to the sixth threshold, the vehicle enters the stationary mode;

[0067] In positioning mode, select the positioning mode duration and positioning function type;

[0068] In the delay mode, if the centripetal acceleration of the tire is detected to be greater than or equal to the seventh threshold value within the second set time, the system returns to the previous working mode; otherwise, the system enters the static mode at the end of the second set time.

[0069] Refer to Table 3, including A1 sleep mode, A2 static mode, A3 positioning mode, A4 operation mode, A5 pressure change mode and A6 delay mode. The six working modes have their own corresponding configuration parameter information.

[0070] Table 3 Tire pressure sensor working mode and parameter configuration table

[0071] In conjunction with Table 3, the specific operation content of the tire pressure sensor in a specific working mode is described in detail.

[0072] A1 sleep mode: This is the default configuration. When the tire pressure sensor is installed in a tire, if the detected tire pressure is greater than or equal to data1 (unit: kPa), the tire automatically exits sleep mode and enters static mode.

[0073] A2 stationary mode: When the centripetal acceleration value is detected to be greater than or equal to the operating parameter data4, the system enters the positioning mode or the operating mode. The operating parameter data5 in the stationary mode is used to determine whether the flameout monitoring function is available. If the flameout monitoring function is available, the operating parameter data6 can be used to set the duration of the flameout monitoring function.

[0074] A3 positioning mode: Execute the operating parameter data7 according to the positioning mode, select the duration of the positioning mode, and select the type of positioning function through the operating parameter data8;

[0075] A4 operating mode: If the centripetal acceleration is greater than or equal to operating parameter data10, the system will maintain the operating state. If the centripetal acceleration is less than operating parameter data11, the system will enter the stationary mode or delay mode. In A4 operating mode, if the tire pressure is detected to have changed by more than operating parameter data12 (unit: kPa) compared to the previously sent pressure, the system will enter the pressure change mode.

[0076] A5 pressure change mode: When the pressure change within the operating parameter data13 (unit: seconds) is less than the operating parameter data14 (unit: kPa), the pressure change mode is exited;

[0077] A6 delay mode: The duration of the delay mode is the operating parameter datal6 (unit: minute). During the operation of parameter data16, if the centripetal acceleration is detected to be greater than or equal to the operating parameter data17, the system returns to the working mode before the delay mode. Otherwise, the system enters the static mode after the execution of operating parameter data16 is completed.

[0078] Conventionally, tire pressure sensors are powered by button batteries. Therefore, the number of working modes designed, how to switch between working modes, and configuration parameter information will greatly affect the service life of the tire pressure sensor. By designing a reasonable number of working modes, switching methods, sampling cycles, and broadcast transmission cycles, the service life of the tire pressure sensor can be extended while ensuring the user's functional experience.

[0079] The following describes the configuration process for tire pressure sensors. Figure 2 shows a schematic diagram of the vehicle ECU and tire pressure sensors according to one embodiment of the present invention. As shown in the figure, taking a small vehicle as an example, the vehicle ECU is installed on the vehicle, and four tire pressure sensors B1, B2, B3, and B4 are installed on each of the vehicle's four tires.

[0080] The process of establishing communication between the vehicle ECU and the tire pressure sensor includes:

[0081] Use offline low-frequency equipment to read the MAC information of each tire pressure sensor through low-frequency wake-up, and write it to the vehicle ECU through OBD to complete the matching process between the tire pressure sensor and the vehicle ECU;

[0082] When a vehicle is assembled at the factory and enters the dynamic hub test bench on the inspection line, a tire rotation test will be performed, which will trigger the tire pressure sensor to send a BLE broadcast message. The vehicle ECU scans the BLE broadcast with the specified MAC address and connects to it. The vehicle ECU can establish two-way Bluetooth communication with four tire pressure sensors at the same time.

[0083] The process by which the vehicle ECU configures the tire pressure sensor according to pre-stored configuration parameters:

[0084] Read the current configuration status of the tire pressure sensor. If the current configuration status shows Z1, it means that the tire pressure sensor is not configured. The configuration parameters stored in the vehicle ECU memory are sent to the tire pressure sensor through the write configuration data feature. If the current configuration status shows Z2, it means that the tire pressure sensor has been configured. The current tire pressure sensor configuration parameters are read back through the read configuration data feature and compared with the configuration parameters in the vehicle ECU memory. If there is a difference, the latest configuration parameters of the vehicle ECU are written to the tire pressure sensor.

[0085] After receiving the configuration parameters sent by the Bluetooth ECU, all tire pressure sensors B1 to B4 will send a response message to the vehicle ECU to ensure that the configuration data update is valid;

[0086] Tire pressure sensors B1 to B4 save the received configuration data in their internal memories and operate according to the updated configuration parameters.

[0087] It should be noted that if the number of tire pressure sensors connected is less than 4 when the vehicle ECU is tested on a dynamic rotating drum test bench, it means that the signals of one or more tire pressure sensors installed on the tires are not detected. In this case, the instrument may prompt a tire pressure system failure and the vehicle will be returned to the maintenance area for inspection.

[0088] The present invention provides a tire pressure sensor configuration method that establishes communication between the vehicle ECU and the tire pressure sensor to achieve effective configuration of the tire pressure sensor. Different operating modes, sampling periods, transmission periods, and transmission frame rates can be configured for different vehicle models. This allows different vehicle models to simply configure the tire pressure sensor's operating mode based on the required functions. Tire pressure sensor products can be fully installed on a platform, allowing all vehicle models to be equipped with the same type of tire pressure sensor, achieving one-to-many compatibility. This tire pressure sensor configuration method has the following advantages:

[0089] 1. The tire pressure offline equipment can be designed in a unified manner, reducing equipment development costs and improving assembly line loading efficiency;

[0090] 2. Tire pressure sensors enable platform-based product design, requiring only one sensor to meet the needs of all vehicle models, significantly shortening development and testing cycles and saving significant development costs. Tire pressure sensors enable platform-based product design, requiring only one sensor to meet the needs of all vehicle models, significantly shortening development and testing cycles and saving significant development costs.

[0091] 3. After-sales maintenance is convenient. The product adopts a platform design. You only need to replace the platform component and then configure the parameters. The vehicle ECU will automatically configure the tire pressure sensor operating parameters. It can be completed without too much professional knowledge.

[0092] 4. Improve product quality. Platform-based product design brings more stable product quality.

[0093] It will be apparent to those skilled in the art that various modifications and variations may be made to the above exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations of the present invention that fall within the scope of the appended claims and their equivalent technical solutions.
