[0025] After the target tire pressure sensor is activated 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, and the target tire pressure sensor is activated again until the preset signal strength exceeds a preset signal strength threshold.

[0046] A tire pressure sensor activation method provided in an embodiment of the present application may be executed by a processor of an activation device when running a corresponding computer program.

[0047] Figure 1 This is a flow chart of a method for activating a tire pressure sensor provided in an embodiment of the present application. For ease of description, only the part related to the present embodiment is shown. The method provided in the present embodiment includes the following steps:

[0048] S100: Determine a target tire pressure sensor and a 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 currently. In actual applications, the signal strengths of the activation signals of the tire pressure sensors of the vehicle may be the same or different; therefore, the corresponding preset signal strength needs to be determined according to the target tire pressure sensor.

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

[0051] S200: Sending an activation signal to the target tire pressure sensor according to a 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 a signal for waking up the tire pressure sensor, and specifically may be a low-frequency instruction transmitted by the activation device through an 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 using the activation signal, that is, to wake up the target tire pressure sensor using the activation signal.

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

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

[0056] In this step, if the target tire pressure sensor is not activated successfully, 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, and the re-determined activation signal is sent to the target tire pressure sensor; the target tire pressure sensor is activated again using the activation signal with the adjusted preset signal strength.

[0057] If the target tire pressure sensor can be activated by the adjusted activation signal, the process is terminated; if the target tire pressure sensor still cannot be activated by the adjusted activation signal, the preset signal strength is adjusted again according to the preset rules based on the last 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, and thus the process is terminated; 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, and the target tire pressure sensor is activated again.

[0059] The embodiment of the present application provides a method for activating a tire pressure sensor, which first activates a target tire pressure sensor using an activation signal of a preset signal strength. If the activation signal of the preset signal strength fails to successfully activate the target tire pressure sensor, the preset signal strength is adjusted according to a preset rule, and the target tire pressure sensor is activated again using the activation signal of the adjusted preset signal strength until the preset signal strength exceeds the 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, the method adjusts the preset signal strength according to the preset rule, and continuously adjusts the preset signal strength of the activation signal, and attempts to activate using activation signals of multiple preset signal strengths to ensure that the target tire pressure sensor can be effectively activated. Therefore, the method can improve the success rate of activating the tire pressure sensor.

[0060] On the basis of the above-mentioned embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, in this embodiment, 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, and the target tire pressure sensor is activated again until the preset signal strength exceeds the preset signal strength threshold, including:

[0061] Get the signal strength adjustment change;

[0062] The preset signal strength is adjusted using the signal strength adjustment variation to obtain an 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 adjustment amount when adjusting the preset signal strength. The signal strength adjustment change can be a preset fixed value, that is, the adjustment amount is the same each time the preset signal strength is adjusted; or it can be a variable, that is, the adjustment amount is different each time the preset signal strength is adjusted.

[0065] Specifically, the preset signal strength is adjusted using the signal strength adjustment variation, that is, the signal strength adjustment variation is increased or decreased on the basis of 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 the activation signal is sent to the target tire pressure sensor to activate the target tire pressure sensor using the activation signal, that is, the target tire pressure sensor is woken up again using the activation signal with the adjusted preset signal strength.

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

[0068] In another specific example, the preset signal strength may be preset as a maximum signal strength; based on the maximum signal strength, when adjusting the preset signal strength, the signal strength adjustment change amount is reduced each time to obtain an adjusted preset signal strength.

[0069] In this embodiment, the preset signal strength is adjusted according to the signal strength adjustment change amount, and the corresponding activation signal is determined, so that the activation signal can be updated efficiently and conveniently, thereby improving the efficiency of activating the tire pressure sensor.

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

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

[0072] If activation feedback information is received within the preset waiting time, it is determined that the target tire pressure sensor is activated successfully;

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

[0074] In actual applications, after the activation device sends an activation signal to the target tire pressure sensor, if the target tire pressure sensor is activated, activation feedback information is sent to the activation device.

[0075] Therefore, the activation device starts timing after sending an activation signal to the target tire pressure sensor, and waits to receive activation feedback information sent by the target tire pressure sensor; after updating the timing, it is determined whether the timing time reaches the preset waiting time; if the timing time does not reach the preset waiting time, it is determined whether the activation feedback information is received; if the activation feedback information is received within the preset waiting time, it is determined that the target tire pressure sensor is successfully activated; if the timing time reaches the preset waiting time and no activation feedback information is received, that is, the activation feedback information is not received within the preset waiting time, it is determined that the target tire pressure sensor is not successfully activated.

[0076] According to the method of this embodiment, it is possible to efficiently and conveniently determine whether the target tire pressure sensor is successfully activated, thereby improving the activation efficiency of the tire pressure sensor.

[0077] In actual applications, when activating the target tire pressure sensor, other tire pressure sensors may be activated. For example, when activating the target tire pressure sensor corresponding to the left front wheel, the right front wheel or left rear wheel or other nearby tire pressure sensors may be activated, resulting in the problem of tire cross-talk when activating the tire pressure sensor.

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

[0079] If activation feedback information is received within the preset waiting time, identity verification is performed on the identification information and feature information;

[0080] If the identity authentication is successful, it is determined that the target tire pressure sensor is activated successfully.

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

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

[0083] Specifically, the identity 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 characteristic information in the activation feedback information is consistent with the preset characteristic information of the target tire pressure sensor pre-stored in the activation device; if the identification information and the characteristic information are respectively consistent with the pre-stored preset identification information and the preset characteristic information, it means that the identity authentication of the activation feedback information is passed, and therefore it is determined that the target tire pressure sensor is activated successfully; if the identification information is inconsistent with the pre-stored preset identification information, or the characteristic information is inconsistent with the pre-stored preset characteristic information, it means that the identity authentication of the activation feedback information is not passed, and therefore it is determined that the target tire pressure sensor is not activated successfully.

[0084] In this embodiment, whether the target tire pressure sensor is successfully activated is determined based on the identification information and characteristic information of the tire pressure sensor, which can avoid the problem of tire cross-talk when activating the tire pressure sensor and ensure that the target tire pressure sensor is activated, thereby improving the success rate of tire pressure sensor activation.

[0085] On the basis of the above embodiments, this embodiment further illustrates 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, which means that the target tire pressure sensor cannot be activated by the activation signal with 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 prompt information is used to prompt that the target tire pressure sensor has an abnormal fault; after the prompt information is generated, the prompt information is sent to the prompt device, and the prompt device continuously sends a corresponding signal to prompt the user that the target tire pressure sensor has an abnormal fault, so that the user can perform fault detection and fault handling on the target tire pressure sensor. The prompt device includes a buzzer, an indicator light, a voice player or a display, etc., and the corresponding signal includes a continuous buzzer, a flashing indicator light, etc.

[0089] It can be seen that when this embodiment determines that the adjusted preset signal strength exceeds the preset signal strength threshold, it determines that the target tire pressure sensor has an abnormal fault and generates corresponding prompt information, which can conveniently and intuitively prompt the user that the target tire pressure sensor has an abnormal fault, so as to timely perform fault detection or fault processing on the target tire pressure sensor.

[0090] Figure 2A flowchart of a tire pressure sensor activation method provided by another embodiment of the present application. Figure 2 As shown, based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, in this embodiment, if the target tire pressure sensor is not successfully activated, 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, and the target tire pressure sensor is activated again 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 is 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 activation times of the target tire pressure sensor using the activation signal of the preset signal strength reaches the preset number threshold, the preset signal strength is adjusted according to the preset rule, and 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.

[0093] In this embodiment, when the target tire pressure sensor is activated by using the activation information of the preset signal strength T, if the target tire pressure sensor is not successfully activated, an 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 by using the activation information of the preset signal strength T, and the activation times of activating the target tire pressure sensor by using the activation information of the preset signal strength T are updated;

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

[0095] If the number of activations is less than or equal to the preset number threshold, that is, the number of activations of the target tire pressure sensor using the activation signal with the preset signal strength T does not reach the preset number threshold, the target tire pressure sensor is activated again using the activation information with the preset signal strength T;

[0096] If the number of activations is greater than a preset number threshold, that is, the number of activations of the target tire pressure sensor using an activation signal with a preset signal strength T reaches the preset number threshold, it is necessary to adjust the preset signal strength, specifically, to adjust the preset signal strength according to a preset rule to obtain an adjusted preset signal strength (T=T+△T); △T represents the signal strength adjustment change;

[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 by the activation signal with the maximum preset signal strength within the allowable range, and it is determined that the target tire pressure sensor has an abnormal fault, and a corresponding prompt message is generated;

[0099] If the adjusted preset signal strength T 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.

[0100] In this embodiment, when the target tire pressure sensor is not successfully activated using an activation signal with a preset signal strength, the target tire pressure sensor is activated multiple times using an activation signal with the same preset signal strength to avoid failure to successfully activate the target tire pressure sensor due to signal transmission errors, thereby improving the success rate of tire pressure sensor activation.

[0101] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean 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 the present application.

[0102] It should be noted that the information collection process (such as face image collection process, fingerprint information collection process, etc.) / feature extraction process involved in this application is performed 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.
