[0036] The example embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent similar or analogous elements. The implementations described in the following example embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0037] It should be noted that all actions of obtaining signals, information or data in this application are carried out in accordance with the corresponding data protection regulations and policies of the country where the device is located, and with the authorization given by the corresponding device owner.

[0038] The present disclosure mainly applies to the scene of detecting the tire pressure of each tire on a vehicle. The Bluetooth tire pressure sensor is a commonly used sensor for measuring the tire pressure of a vehicle, and is installed inside the tire. After detecting the tire pressure detection data, the Bluetooth tire pressure sensor located inside the tire transmits the tire pressure detection data to the signal receiver located inside the vehicle. However, the Bluetooth tire pressure sensor is located outside the vehicle, and the signal receiver is located inside the vehicle. During data transmission, it is generally necessary to penetrate the vehicle body, which requires the Bluetooth tire pressure sensor to have strong transmission power. However, strong transmission power will inevitably increase power consumption, thereby affecting the service life of the Bluetooth tire pressure sensor.

[0039] In addition, in actual tire pressure detection scenarios, it is also necessary to position each tire pressure sensor to determine which tire the detected tire pressure detection data belongs to. In the tire pressure sensor positioning method provided in the related art, the vehicle driving direction is set as the positive direction of the X-axis, and the data corresponding to the Z-axis acceleration rising and the X-axis acceleration greater than zero corresponds to the left wheel rotating counterclockwise, the data corresponding to the Z-axis acceleration rising and the X-axis acceleration less than zero corresponds to the right wheel rotating clockwise, and vice versa, thereby effectively identifying the position of the corresponding tire corresponding to the tire pressure sensor ID. This method needs to detect the acceleration in the X-axis and Z-axis directions of the tire pressure sensor at the same time. Therefore, the detection process and data processing process are relatively complex, and there are often miscalculations, and the positioning accuracy is limited.

[0040] To solve the above problems, the present disclosure provides a tire pressure detection system, method, storage medium and vehicle, and the specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0041] Figure 1 is a structural block diagram of a tire pressure detection system according to an exemplary embodiment, as shown in Figure 1 , the tire pressure detection system 100 comprises:

[0042] A plurality of tire pressure detection devices 101 (four are exemplarily shown in Figure 1 ), a signal receiving device 102 corresponding to the tire pressure detection device 101 one by one, and a controller 103 connected with the signal receiving device 102; wherein the tire pressure detection device 101 and the corresponding signal receiving device 102 perform wireless communication (such as Bluetooth communication), and different tire pressure detection devices 101 are used to detect the tire pressure of different tires of the vehicle.

[0043] In the present disclosure, one tire pressure detection device 101 can be installed inside one tire, which can be a Bluetooth tire pressure sensor for example, and the signal receiving device 102 can be a Bluetooth key anchor point on the vehicle for example.

[0044] Exemplarily, Figure 2 is a schematic diagram of a conventional vehicle tire pressure sensor arrangement, as shown in Figure 2 , in the related art, Bluetooth tire pressure sensors T1, T2, T3, T4 are respectively arranged inside the left front wheel, the left rear wheel, the right rear wheel and the right front wheel of the vehicle, and Figure 2 , in the schematic diagram shown in , a receiver is arranged inside the vehicle, which can receive the tire pressure detection data sent by T1, T2, T3, T4, but a higher transmission power is required to penetrate the vehicle body for data transmission, which will cause high power consumption. Figure 3 is a schematic diagram of the distribution of Bluetooth key anchor points on a vehicle according to an exemplary embodiment, a Bluetooth key anchor point K1, a Bluetooth key anchor point K2, a Bluetooth key anchor point K3, and a Bluetooth key anchor point K4 are respectively arranged in the left front, the left rear, the right rear and the right front of the vehicle, and it can be found that the four Bluetooth key anchor points correspond one by one with Figure 2 four Bluetooth tire pressure sensors T1, T2, T3, T4 shown in , that is, T1 and K1 correspond to each other, T2 and K2 correspond to each other, T3 and K3 correspond to each other, and T4 and K4 correspond to each other, as Figure 2 and Figure 3As shown, the Bluetooth tire pressure sensor and the corresponding Bluetooth key anchor point are not only adjacent in deployment position, but also located outside the vehicle. If the Bluetooth tire pressure sensor can directly send the detected tire pressure detection data to the corresponding Bluetooth key anchor point, a smaller transmission power can be used to achieve the transmission of the tire pressure detection data, which can significantly save the power consumption of the Bluetooth tire pressure sensor, and thus can improve the service life of the tire pressure sensor.

[0045] For example, Figure 4 is a layout schematic diagram of a Bluetooth key anchor point and a Bluetooth tire pressure sensor hybrid system according to an example embodiment. As shown, each Bluetooth tire pressure sensor is paired with the Bluetooth key anchor point at the corresponding position. Compared with the traditional tire pressure detection scheme shown in Figure 4 , the receiver located inside the vehicle can be removed. The tire pressure detection data obtained by the Bluetooth tire pressure sensor can be transmitted through the corresponding Bluetooth key anchor point. Figure 2

[0046] Therefore, in the present disclosure, for each tire pressure detection device 101, the tire pressure detection device 101 is configured to send tire pressure detection data to a corresponding target signal receiving device.

[0047] Among them, the target signal receiving device refers to the signal receiving device 102 corresponding to the tire pressure detection device 101, as shown in Figure 4 , assuming that the tire pressure detection device 101 is a Bluetooth tire pressure sensor T1, the target signal receiving device is the Bluetooth key anchor point K1 corresponding to T1.

[0048] In addition, the tire pressure detection device 101 can send tire pressure detection data to the corresponding target signal receiving device according to the target transmission power. The signal radiation area corresponding to the target transmission power is the target area, and the target signal receiving device is located in the target area. Other signal receiving devices except the target signal receiving device are located outside the target area, so that only the target signal receiving device corresponding to the tire pressure detection device 101 can receive the tire pressure detection data transmitted by the tire pressure detection device 101, and other signal receiving devices except the target signal receiving device cannot receive the tire pressure detection data sent by the tire pressure detection device 101.

[0049] For example, as shown in Figure 4 , the signal carrying tire pressure detection data emitted by the Bluetooth tire pressure sensor T1 can only be received by the Bluetooth key anchor point K1, and other Bluetooth key anchor points K2, K3, and K4 except K1 cannot receive the signal carrying tire pressure detection data emitted by T1.

[0050] ​The deployment position distance between the tire pressure detection device 101 and the corresponding target signal receiving device is less than or equal to a preset distance threshold, and the target transmission power is preset according to the deployment position distance. In an implementation, the transmission power of each tire pressure detection device 101 can be reduced based on the conventional tire pressure detection scheme as shown in Figure 2 to a level that only the nearby Bluetooth key anchor point can receive the transmission signal of the tire pressure detection device 101.

[0051] It should be noted that the size of the target transmission power depends on the deployment position distance between the tire pressure detection device 101 and the corresponding target signal receiving device, and whether there is an obstacle between the two, etc. For example, the closer the deployment position distance, the smaller the target transmission power. The target transmission power is smaller in the case where there is no obstacle between the two than in the case where there is an obstacle.

[0052] The target signal receiving device is configured to send the received tire pressure detection data to the controller 103.

[0053] In a possible implementation, the controller 103 and each signal receiving device 102 can be connected through Ethernet, so that the target signal receiving device can send the tire pressure detection data to the controller 103 through Ethernet transmission.

[0054] The controller 103 is configured to determine the tire pressure of the target tire according to the tire pressure detection data, wherein the target tire is the tire corresponding to the tire pressure detection device 101.

[0055] In the present disclosure, the target signal receiving device corresponding to the tire pressure detection device 101 can also be configured to send a position indication message of the target signal receiving device to the controller 103, wherein the position indication message can include identification information of the target signal receiving device, or can include position information of the target signal receiving device, so that the controller 103 can be configured to locate the target tire according to the position indication message.

[0056] For example, continuing with the example of Figure 4For example, the Bluetooth tire pressure sensor T1 and the Bluetooth key anchor K1 corresponding to T1 in FIG. 1 are taken as an example. After receiving the tire pressure detection data sent by T1, K1 can send the tire pressure detection data and the position information corresponding to K1 (for example, recorded as point A) to the controller 103. The controller 103 can determine that the information is sent by the Bluetooth key anchor K1 located at the left front of the vehicle according to the position information of K1, and further determine that the Bluetooth tire pressure sensor corresponding to the Bluetooth key anchor K1 is T1, and T1 is a tire pressure sensor deployed inside the left front wheel. Therefore, it can be determined that the target tire is the left front wheel. The above example is only illustrative, and the present disclosure is not limited in this regard.

[0057] In addition, the tire pressure detection system 100 provided by the present disclosure can further include a tire pressure display device connected with the controller 103. In this way, the controller 103 can display the tire pressure of each tire through the tire pressure display device after determining the tire pressure of the target tire.

[0058] In another possible implementation, the tire pressure detection system 100 can further include an alarm device connected with the controller 103. In this way, the alarm device can timely alarm in the case that the tire pressure of the target tire is abnormal.

[0059] By using the above system, the transmission power of the tire pressure detection device can be reduced, thereby prolonging the service life of the tire pressure detection device. In addition, compared with the positioning method of the tire pressure sensor provided in the related art, which needs to detect the acceleration in the X-axis and Z-axis directions of the tire pressure sensor at the same time, the positioning complexity of the tire pressure sensor can be greatly simplified, the positioning efficiency is improved, and the positioning accuracy is ensured. Moreover, the tire pressure detection system provided by the present disclosure can remove the receiver inside the vehicle, thereby reducing the design cost of the tire pressure detection system.

[0060] Figure 5 is a flowchart of a tire pressure detection method according to an example embodiment. The method can be applied to the tire pressure detection system 100 as shown in Figure 1 FIG. 1, which includes a plurality of tire pressure detection devices 101 as shown in Figure 1 FIG. 1, a signal receiving device 102 corresponding to each tire pressure detection device 101, and a controller 103 connected with the signal receiving device 102. The tire pressure detection device 101 and the corresponding signal receiving device 102 perform wireless communication, for example, through Bluetooth. Different tire pressure detection devices 101 are used to detect the tire pressure of different tires of the vehicle, and one tire pressure detection device 101 can be installed inside one tire. In addition, the tire pressure detection device 101 can include a Bluetooth tire pressure sensor (for example, T1 in FIG. 1). Figure 4T1, T2, T3, T4 in FIG. 1), the signal receiving device 102 can include a Bluetooth key anchor point (as shown in FIG. 1, K1, K2, K3, K4). Figure 4

[0061] As shown in FIG. 1, the method includes the following steps: Figure 5

[0062] In step S501, for each tire pressure detection device, the tire pressure detection device sends tire pressure detection data to a corresponding target signal receiving device.

[0063] The target signal receiving device refers to the signal receiving device 102 corresponding to the tire pressure detection device 101, as shown in FIG. 1, assuming that the tire pressure detection device 101 is a Bluetooth tire pressure sensor T1, the target signal receiving device is the Bluetooth key anchor point K1 corresponding to T1. Figure 4

[0064] In this step, the tire pressure detection device 101 can send the tire pressure detection data to the corresponding target signal receiving device according to a target transmission power, the signal radiation area corresponding to the target transmission power is a target area, the target signal receiving device is located in the target area, and other signal receiving devices except the target signal receiving device are located outside the target area.

[0065] In this way, it can be ensured that only the target signal receiving device corresponding to the tire pressure detection device 101 can receive the tire pressure detection data transmitted by the tire pressure detection device 101, and other signal receiving devices except the target signal receiving device cannot receive the tire pressure detection data sent by the tire pressure detection device 101.

[0066] For example, as shown in FIG. 1, the signal carrying tire pressure detection data emitted by the Bluetooth tire pressure sensor T1 can only be received by the Bluetooth key anchor point K1, and other Bluetooth key anchor points K2, K3, K4 cannot receive the signal carrying tire pressure detection data emitted by T1. Figure 4

[0067] In addition, the target transmission power can be pre-set in the following manner:

[0068] The target transmission power is pre-set according to a deployment position distance, wherein the deployment position distance is the distance between the tire pressure detection device 101 and the corresponding target signal receiving device, and the deployment position distance is less than or equal to the pre-set distance threshold.

[0069] In an implementation manner, the target transmission power can be pre-set according to a deployment position distance, wherein the deployment position distance is the distance between the tire pressure detection device 101 and the corresponding target signal receiving device, and the deployment position distance is less than or equal to the pre-set distance threshold. Figure 2 ​​​​The transmitting power of each tire pressure detection device 101 is reduced based on the conventional tire pressure detection scheme shown, to only the nearby Bluetooth key anchor point can receive the transmitting signal of the tire pressure detection device 101.

[0070] In step S502, the tire pressure detection data received by the target signal receiving device is sent to the controller.

[0071] In an implementation, the controller 103 can be connected with each signal receiving device 102 through Ethernet, so that the target signal receiving device can send the tire pressure detection data to the controller 103 through Ethernet transmission.

[0072] In step S503, the tire pressure of the target tire is determined by the controller according to the tire pressure detection data, and the target tire is the tire corresponding to the tire pressure detection device.

[0073] In an implementation, the position indication message of the target signal receiving device can also be sent to the controller 103 by the target signal receiving device, so that the target tire is located by the controller 103 according to the position indication message.

[0074] The position indication message can include the identification information of the target signal receiving device, or can include the position information of the target signal receiving device.

[0075] For example, continue to take the Bluetooth tire pressure sensor T1 in Figure 4 and the Bluetooth key anchor point K1 corresponding to T1 as an example, after receiving the tire pressure detection data sent by T1, K1 can send the tire pressure detection data and the position information (for example, can be recorded as point A) corresponding to K1 to the controller 103, and the controller 103 can determine that this information is sent by the Bluetooth key anchor point K1 located at the left front of the vehicle according to the position information of K1, and further determine that the Bluetooth tire pressure sensor corresponding to the Bluetooth key anchor point K1 is T1, and T1 is a tire pressure sensor deployed inside the left front wheel, so it can be determined that the target tire is the left front wheel. The above example is only illustrative, and the present disclosure is not limited in this regard.

[0076] By using the above method, the transmitting power of the tire pressure detection device can be reduced, and thus the service life of the tire pressure detection device can be prolonged. In addition, compared with the positioning method of the tire pressure sensor provided in the related art, the positioning method of the tire pressure sensor in the present disclosure can greatly simplify the positioning complexity of the tire pressure sensor, improve the positioning efficiency, and ensure the positioning accuracy. In addition, the tire pressure detection system provided in the present disclosure can remove the receiver in the vehicle, and thus the design cost of the tire pressure detection system can be reduced.

[0077] The present disclosure further provides a computer readable storage medium, which stores computer program instructions, and the computer program instructions are executed by a processor to implement the steps of the tire pressure detection method provided in the present disclosure.
