[0002] Tire pressure sensors are devices installed inside vehicle tires or on wheel rims to monitor the pressure and temperature inside the tire and transmit this data wirelessly to a tire pressure receiver. When a tire pressure sensor is depleted of power or damaged, it needs to be replaced and reactivated.

[0003] Current technical solutions involve activating the target tire pressure sensor by sending a fixed low-frequency signal to it via an activation device. However, this method has a low success rate in activating the tire pressure sensor.

[0004] Therefore, how to improve the success rate of activating tire pressure sensors is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0013] An activation signal is sent to the target tire pressure sensor according to the adjusted preset signal strength, and the target tire pressure sensor is activated again until the preset signal strength exceeds the preset signal strength threshold.

[0014] In one embodiment, the process of determining whether the target tire pressure sensor has been successfully activated includes:

[0015] After sending the activation signal to the target tire pressure sensor, determine whether the activation feedback information sent by the target tire pressure sensor is received within a preset waiting time.

[0016] If the activation feedback information is received within the preset waiting time, it is determined that the target tire pressure sensor has been successfully activated.

[0017] If the activation feedback information is not received within the preset waiting time, it is determined that the target tire pressure sensor has not been successfully activated.

[0018] In one embodiment, the activation feedback information includes the identification information and feature information of the tire pressure sensor; the step of determining that the target tire pressure sensor has been successfully activated if the activation feedback information is received within the preset waiting time includes:

[0019] If the activation feedback information is received within the preset waiting time, the identity information and the feature information are verified.

[0020] If the authentication is successful, the target tire pressure sensor is confirmed to be successfully activated.

[0021] In one embodiment, the method further includes:

[0022] If the preset signal strength exceeds the preset signal strength threshold, it is determined that the target tire pressure sensor has an abnormal fault, and a corresponding prompt message is generated.

[0023] In one embodiment, if the target tire pressure sensor fails to activate successfully, the preset signal strength is adjusted according to a preset rule, and an activation signal is sent to the target tire pressure sensor according to the adjusted preset signal strength to reactivate the target tire pressure sensor until the preset signal strength exceeds a preset signal strength threshold, including:

[0024] If the target tire pressure sensor fails to activate, an activation signal is sent to the target tire pressure sensor again with a preset signal strength to activate the target tire pressure sensor.

[0025] After activating the target tire pressure sensor a preset number of times using the activation signal with the preset signal strength, the preset signal strength is adjusted according to a preset rule, and an activation signal is sent to the target tire pressure sensor according to the adjusted preset signal strength to activate the target tire pressure sensor again, until the preset signal strength exceeds the preset signal strength threshold.

[0026] Secondly, this application also provides an activation device for a tire pressure sensor. The device includes:

[0027] A determination module is used to determine the target tire pressure sensor and the preset signal strength corresponding to the target tire pressure sensor;

If the activation signal of the preset signal strength fails to activate the target tire pressure sensor, the preset signal strength is adjusted according to preset rules, and the target tire pressure sensor is activated again using the adjusted activation signal strength, until the preset signal strength exceeds a preset signal strength threshold. In other words, this method adjusts the preset signal strength according to preset rules when the target tire pressure sensor fails to be activated using the initial activation signal. By continuously adjusting the preset signal strength and attempting activation with multiple preset signal strengths, the method ensures that the target tire pressure sensor can be effectively activated. Therefore, this method can improve the success rate of activating tire pressure sensors.

[0046] The tire pressure sensor activation method provided in this application embodiment can be executed by the processor of the activation device when running a corresponding computer program.

[0047] Figure 1 The flowchart illustrates a tire pressure sensor activation method according to an embodiment of this application. For ease of explanation, only the parts relevant to this embodiment are shown. The method provided in this embodiment includes the following steps:

[0048] S100: Determine the target tire pressure sensor and the preset signal strength corresponding to the target tire pressure sensor.

[0049] The target tire pressure sensor refers to the tire pressure sensor that needs to be activated. In practical applications, the signal strength of the activation signals of each tire pressure sensor in a vehicle can be the same or different; therefore, it is necessary to determine the corresponding preset signal strength based on the target tire pressure sensor.

[0050] Specifically, signal strength refers to the power level of the signal, usually expressed in dBm. During the activation process of a tire pressure sensor, determining the preset signal strength corresponding to the target tire pressure sensor is equivalent to determining the power level of the activating device.

[0051] S200: Send an activation signal to the target tire pressure sensor according to the preset signal strength to activate the target tire pressure sensor.

[0052] After determining the preset signal strength, an activation signal is determined based on the preset signal strength. The activation signal is used to wake up the tire pressure sensor, which can be a low-frequency command transmitted by the activation device through the antenna.

[0053] After determining the activation signal according to the preset signal strength, the activation device sends the activation signal to the target tire pressure sensor to activate the target tire pressure sensor, that is, to wake up the target tire pressure sensor by using the activation signal.

[0054] S300: If the target tire pressure sensor is not activated successfully, the preset signal strength is adjusted according to the preset rules, and an activation signal is sent to the target tire pressure sensor according to the adjusted preset signal strength to activate the target tire pressure sensor again until the preset signal strength exceeds the preset signal strength threshold.

[0055] In practical applications, the target tire pressure sensor may be activated by an activation signal, or the activation signal may not be able to activate the target tire pressure sensor.

[0056] In this step, if the target tire pressure sensor fails to activate, the preset signal strength is adjusted according to the preset rules, and the activation signal is re-determined according to the adjusted preset signal strength. The re-determined activation signal is then sent to the target tire pressure sensor to reactivate it using the activation signal with the adjusted preset signal strength.

[0057] If the target tire pressure sensor can be activated using the adjusted activation signal, the process ends; if the target tire pressure sensor still cannot be activated using the adjusted activation signal, the preset signal strength is adjusted again according to the preset rules based on the previous adjustment of the preset signal strength.

[0058] Then, it is determined whether the adjusted preset signal strength exceeds the preset signal strength threshold. If the adjusted preset signal strength exceeds the preset signal strength threshold, it means that the target tire pressure sensor cannot be activated using the activation signal with the maximum preset signal strength within the allowable range, so the process ends. If the adjusted preset signal strength does not exceed the preset signal strength threshold, an activation signal is sent to the target tire pressure sensor according to the adjusted preset signal strength to activate the target tire pressure sensor again.

[0059] This application provides a method for activating a tire pressure sensor. First, the target tire pressure sensor is activated using an activation signal of a preset signal strength. If the activation signal of the preset signal strength fails to activate the target tire pressure sensor, the preset signal strength is adjusted according to preset rules, and the target tire pressure sensor is activated again using the adjusted activation signal strength, until the preset signal strength exceeds a preset signal strength threshold. In other words, when the target tire pressure sensor is not successfully activated using the activation signal of the preset signal strength, this method adjusts the preset signal strength according to preset rules. By continuously adjusting the preset signal strength of the activation signal and attempting activation with activation signals of various preset signal strengths, the method ensures that the target tire pressure sensor can be effectively activated. Therefore, this method can improve the success rate of activating the tire pressure sensor.

[0060] Based on the above embodiments, this embodiment further explains and optimizes the technical solution. Specifically, in this embodiment, the preset signal strength is adjusted according to preset rules, and an activation signal is sent to the target tire pressure sensor according to the adjusted preset signal strength to reactivate the target tire pressure sensor until the preset signal strength exceeds the preset signal strength threshold, including:

[0061] Acquire the signal strength adjustment change;

[0062] The preset signal strength is adjusted by using the signal strength adjustment change amount to obtain the adjusted preset signal strength;

[0063] An activation signal is sent to the target tire pressure sensor according to the adjusted preset signal strength, and the target tire pressure sensor is activated again until the preset signal strength exceeds the preset signal strength threshold.

[0064] The signal strength adjustment change refers to the amount of adjustment when the preset signal strength is adjusted. The signal strength adjustment change can be a preset fixed value, meaning that the adjustment amount is the same each time the preset signal strength is adjusted; or it can be a variable, meaning that the adjustment amount is different each time the preset signal strength is adjusted.

[0065] Specifically, the preset signal strength is adjusted by adjusting the signal strength adjustment amount, that is, by increasing or decreasing the signal strength adjustment amount based on the preset signal strength, to obtain the adjusted preset signal strength.

[0066] After determining the adjusted preset signal strength, an activation signal is determined based on the adjusted preset signal strength and sent to the target tire pressure sensor to activate the target tire pressure sensor, that is, to wake up the target tire pressure sensor again using the activation signal with the adjusted preset signal strength.

[0067] In one specific example, the preset signal strength can be preset to the minimum signal strength value; based on this minimum signal strength value, when adjusting the preset signal strength, the signal strength adjustment amount is increased each time to obtain the adjusted preset signal strength.

[0068] In another specific example, the preset signal strength can be preset to the maximum signal strength value; based on this maximum signal strength value, when adjusting the preset signal strength, the amount of signal strength adjustment is reduced each time to obtain the adjusted preset signal strength.

[0069] In this embodiment, the preset signal strength is adjusted according to the change in signal strength, and the corresponding activation signal is determined. This enables efficient and convenient updating of the activation signal and improves the efficiency of activating the tire pressure sensor.

[0070] Based on the above embodiments, this embodiment further explains and optimizes the technical solution. Specifically, in this embodiment, the process of determining whether the target tire pressure sensor has been successfully activated includes:

[0071] After sending an activation signal to the target tire pressure sensor, determine whether the activation feedback information sent by the target tire pressure sensor is received within a preset waiting time.

[0072] If activation feedback is received within the preset waiting time, the target tire pressure sensor is confirmed to have been successfully activated.

[0073] If no activation feedback is received within the preset waiting time, it is determined that the target tire pressure sensor has not been successfully activated.

[0074] In practical applications, after the activation device sends an activation signal to the target tire pressure sensor, if the target tire pressure sensor is activated, it will send activation feedback information back to the activation device.

[0075] Therefore, after sending an activation signal to the target tire pressure sensor, the activation device starts timing and waits to receive activation feedback information from the target tire pressure sensor. After updating the timing, it checks whether the timing duration has reached the preset waiting time. If the timing duration has not reached the preset waiting time, it determines whether activation feedback information has been received. If activation feedback information is received within the preset waiting time, the target tire pressure sensor is determined to be successfully activated. If the timing duration reaches the preset waiting time and no activation feedback information is received, that is, no activation feedback information is received within the preset waiting time, the target tire pressure sensor is determined to be unactivated.

[0076] The method described in this embodiment can efficiently and conveniently determine whether the target tire pressure sensor has been successfully activated, thereby improving the activation efficiency of the tire pressure sensor.

[0077] In practical applications, activating a target tire pressure sensor may also activate other tire pressure sensors. For example, when activating the target tire pressure sensor corresponding to the left front wheel, it may activate the tire pressure sensors on the right front wheel, left rear wheel, or other nearby tires, leading to tire crossover issues during sensor activation.

[0078] Based on the aforementioned technical problems and the above embodiments, this embodiment further explains and optimizes the technical solution. Specifically, in this embodiment, the activation feedback information includes the identification information and feature information of the tire pressure sensor; if activation feedback information is received within a preset waiting time, it is determined that the target tire pressure sensor has been successfully activated, including:

[0079] If an activation feedback message is received within the preset waiting time, the identity information and feature information will be verified.

[0080] If authentication is successful, the target tire pressure sensor is confirmed to be activated successfully.

[0081] The identification information refers to the information used to uniquely identify the tire pressure sensor. The feature information refers to pre-stored information related to the characteristics of the tire pressure sensor. Specifically, the feature information includes the signal strength of the required activation signal, the tire pressure sensor model, and manufacturing information.

[0082] In this embodiment, after receiving the activation feedback information within a preset waiting time, the activation feedback information is authenticated based on the identification information and feature information to determine whether the activation feedback information is sent by the target tire pressure sensor.

[0083] Specifically, the authentication process includes: determining whether the identification information in the activation feedback information is consistent with the preset identification information of the target tire pressure sensor pre-stored in the activation device; determining whether the feature information in the activation feedback information is consistent with the preset feature information of the target tire pressure sensor pre-stored in the activation device; if the identification information and feature information are consistent with the pre-stored preset identification information and preset feature information respectively, it indicates that the authentication of the activation feedback information has passed, and therefore the target tire pressure sensor has been successfully activated; if the identification information is inconsistent with the pre-stored preset identification information, or the feature information is inconsistent with the pre-stored preset feature information, it indicates that the authentication of the activation feedback information has failed, and therefore the target tire pressure sensor has not been successfully activated.

[0084] In this embodiment, the determination of whether the target tire pressure sensor has been successfully activated is based on the identification and feature information of the tire pressure sensor. This can avoid the problem of tire crossover that may occur when activating the tire pressure sensor, ensure that the target tire pressure sensor is activated, and thus improve the activation success rate of the tire pressure sensor.

[0085] Based on the above embodiments, this embodiment further explains and optimizes the technical solution. Specifically, in this embodiment, the method further includes:

[0086] If the preset signal strength exceeds the preset signal strength threshold, it is determined that the target tire pressure sensor has an abnormal fault, and a corresponding prompt message is generated.

[0087] In this embodiment, when it is determined that the adjusted preset signal strength exceeds the preset signal strength threshold, that is, when the target tire pressure sensor cannot be activated even with the activation signal of the maximum preset signal strength within the allowable range, it is determined that the target tire pressure sensor has an abnormal fault, and a corresponding prompt message is generated.

[0088] The system includes a notification message to indicate a malfunction in the target tire pressure sensor. After generating the notification message, it is sent to a notification device, which continuously emits corresponding signals to alert the user of the malfunction, allowing the user to detect and address the issue. The notification device may include a buzzer, indicator light, voice player, or display, and the corresponding signals may include a continuous buzzer or a flashing indicator light.

[0089] As can be seen, this embodiment determines that the target tire pressure sensor has an abnormal fault when the adjusted preset signal strength exceeds the preset signal strength threshold, and generates corresponding prompt information. This can conveniently and intuitively prompt the user that the target tire pressure sensor has an abnormal fault, so that the target tire pressure sensor can be detected or handled in a timely manner.

[0090] Figure 2A flowchart illustrating a method for activating a tire pressure sensor according to another embodiment of this application. (In conjunction with...) Figure 2 As shown, based on the above embodiments, this embodiment further explains and optimizes the technical solution. Specifically, in this embodiment, if the target tire pressure sensor fails to activate successfully, the preset signal strength is adjusted according to preset rules, and an activation signal is sent to the target tire pressure sensor according to the adjusted preset signal strength to reactivate the target tire pressure sensor until the preset signal strength exceeds the preset signal strength threshold, including:

[0091] If the target tire pressure sensor is not activated successfully, an activation signal will be sent to the target tire pressure sensor again according to the preset signal strength to activate the target tire pressure sensor.

[0092] After the number of activations of the target tire pressure sensor using an activation signal with a preset signal strength reaches a preset threshold, the preset signal strength is adjusted according to a preset rule, and an activation signal is sent to the target tire pressure sensor according to the adjusted preset signal strength to activate the target tire pressure sensor again, until the preset signal strength exceeds the preset signal strength threshold.

[0093] In this embodiment, when the target tire pressure sensor is activated using the activation information of the preset signal strength T, if the target tire pressure sensor is not successfully activated, the activation signal is sent to the target tire pressure sensor again according to the preset signal strength T, that is, the target tire pressure sensor is activated again using the activation information of the preset signal strength T, and the number of activations of the target tire pressure sensor using the activation information of the preset signal strength T is updated.

[0094] Determine whether the number of activations is less than or equal to a preset threshold.

[0095] If the number of activations is less than or equal to the preset threshold, that is, the number of activations of the target tire pressure sensor using the activation signal with preset signal strength T has not reached the preset threshold, then the target tire pressure sensor will be activated again using the activation information with preset signal strength T.

[0096] If the number of activations exceeds the preset threshold, that is, the number of activations of the target tire pressure sensor using the activation signal with preset signal strength T reaches the preset threshold, then the preset signal strength needs to be adjusted. Specifically, the preset signal strength is adjusted according to preset rules to obtain the adjusted preset signal strength (T = T + ΔT); ΔT represents the amount of signal strength adjustment.

[0097] Determine whether the adjusted preset signal strength T exceeds the preset signal strength threshold;

[0098] If the adjusted preset signal strength T exceeds the preset signal strength threshold, it means that the target tire pressure sensor cannot be activated even with the activation signal of the maximum preset signal strength within the allowable range. This indicates that the target tire pressure sensor has an abnormal fault and generates a corresponding prompt message.

[0099] If the adjusted preset signal strength T does not exceed the preset signal strength threshold, then an activation signal is sent to the target tire pressure sensor according to the adjusted preset signal strength to reactivate the target tire pressure sensor.

[0100] In this embodiment, when the activation of the target tire pressure sensor using an activation signal of preset signal strength fails, the same activation signal of preset signal strength is used to activate the target tire pressure sensor multiple times. This avoids failure to activate the target tire pressure sensor due to signal transmission errors and can improve the activation success rate of the tire pressure sensor.

[0101] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0102] It should be noted that the information collection process (such as the facial image collection process, fingerprint information collection process, etc.) / feature extraction process involved in this application is carried out with the user's knowledge and permission. That is, the information collection process / feature extraction process complies with the requirements of laws and regulations and does not constitute an act that harms the public interest.
