[0063] Figure 10 This is a block diagram illustrating a tire pressure sensor according to an exemplary embodiment. Detailed Implementation

[0064] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0065] Figure 1 This is a flowchart illustrating a vehicle tire pressure detection method according to an exemplary embodiment. This method can be applied to an in-vehicle wireless terminal. Figure 1 As shown, the method may include S101 to S103.

[0066] S101, based on the vehicle status, determines the target communication mode of the vehicle-mounted wireless terminal and controls the vehicle-mounted wireless terminal to enter the target communication mode.

[0067] For example, vehicle status may include vehicle speed and vehicle ignition status. The target communication mode can be set according to the communication module in the vehicle wireless terminal.

[0068] For example, if the communication module of an in-vehicle wireless terminal includes a Bluetooth module, the target communication mode can include Bluetooth Low Energy (BLE) mode and regular Bluetooth mode. The Bluetooth module operates bidirectionally, capable of both sending and receiving information, thus enabling rapid data transmission and reception, but consuming more energy. Bluetooth Low Energy (BLE) mode consumes even less power than regular Bluetooth mode; however, when the Bluetooth module enters BLE mode, it can only transmit a limited amount of data. For instance, in this mode, the Bluetooth module can be used to transmit communication commands.

[0069] For example, if the communication module of the vehicle-mounted wireless terminal also includes a radio frequency (RF) module, the target communication mode can also include an RF communication mode. The RF module operates unidirectionally; that is, it can be used to send or receive information, but not simultaneously. The RF module in the vehicle-mounted wireless terminal's communication module is used for receiving information, while the RF module for sending information can be located in the tire pressure sensor. The RF module consumes less power than a Bluetooth module; however, its efficiency is lower when the vehicle speed is below a certain threshold, resulting in longer intervals between information transmissions. Therefore, at low vehicle speeds, the vehicle-mounted wireless terminal may struggle to obtain the necessary information in real time.

[0070] Therefore, by determining the target communication mode of the vehicle-mounted wireless terminal based on the vehicle's status and controlling the vehicle-mounted wireless terminal to enter the target communication mode, the communication mode of the vehicle-mounted wireless terminal can be adapted to the actual status of the vehicle, thereby reducing the energy consumption of the vehicle-mounted wireless terminal during the communication process and extending the equipment's usage time.

[0071] S102 sends a communication mode command to the tire pressure sensor.

[0072] The communication mode command is used to control the tire pressure sensor to enter the target communication mode. The communication mode command can be sent to the tire pressure sensor via the Bluetooth module of the vehicle's wireless terminal.

[0073] In this way, the vehicle wireless terminal and tire pressure sensor can be put into the same communication mode by communication mode commands to ensure smooth communication.

[0074] S103: If tire pressure information is received from the tire pressure sensor, determine whether there is any abnormality in the vehicle's tires based on the tire pressure information.

[0075] The vehicle-mounted wireless terminal is used for location data collection, vehicle body data collection and transmission, and communication with the backend system to achieve vehicle information monitoring and control. It is a device for remote vehicle monitoring. The tire pressure monitoring system (TPMS) is a system installed on the vehicle to monitor tire pressure in some way and issue an alarm when one or more tires are underinflated. Currently, the vehicle-mounted wireless terminal and the TPMS are independent, increasing the procurement and maintenance costs for vehicle manufacturers. However, in the vehicle tire pressure detection method disclosed in this paper, tire anomaly detection can be achieved through the vehicle-mounted wireless terminal, which is equivalent to integrating the core TPMS algorithm module of the TPMS system into the vehicle-mounted wireless terminal, making the equipment structure more rational. Furthermore, the vehicle-mounted wireless terminal itself has powerful communication capabilities, and information transmission and reception can be achieved by reusing the communication module within the vehicle-mounted wireless terminal.

[0076] Figure 2 This is a flowchart illustrating a vehicle tire pressure detection method according to an exemplary embodiment. This method can be applied to tire pressure sensors on a vehicle. Figure 2 As shown, the method may include S201 to S202.

[0077] S201, in response to the received communication mode command sent by the vehicle-mounted wireless terminal, enter the target communication mode corresponding to the communication mode command.

[0078] S202, when the target communication mode allows the tire pressure sensor to send tire pressure information, send tire pressure information to the vehicle wireless terminal.

[0079] In this way, the tire pressure sensor can enter the same communication mode as the vehicle wireless terminal through the received communication mode command, so as to ensure the smooth progress of subsequent communication. This allows the vehicle wireless terminal to determine whether there is any abnormality in the vehicle's tires, thereby ensuring the safety of driving.

[0080] The above technical solution determines the target communication mode of the vehicle-mounted wireless terminal based on the vehicle's status and controls the terminal to enter that mode. A communication mode command is sent to the tire pressure sensor, controlling it to enter the target mode. This adapts the communication mode of the wireless terminal and the tire pressure sensor to the vehicle's actual condition, reducing energy consumption and extending device lifespan. If tire pressure information is received from the sensor, it determines whether there are any abnormalities in the tires. This allows the wireless terminal to identify tire abnormalities, thus ensuring driving safety.

[0081] Figure 3The diagram illustrates the signaling interaction between an onboard wireless terminal and a tire pressure sensor when implementing the vehicle tire pressure detection method provided in this disclosure, according to one embodiment. Figure 3 The steps shown are in conjunction with the above. Figure 1 and Figure 2 The description is consistent with the actual situation, so I will not repeat it here.

[0082] Figure 4 A signaling interaction diagram between an onboard wireless terminal and a tire pressure sensor is shown in another embodiment of the vehicle tire pressure detection method provided in this disclosure. Figure 4 As shown, the vehicle tire pressure detection method may include steps S401 to S403.

[0083] S401 If the vehicle is in a powered-off state and has not received a wake-up command, the vehicle wireless terminal determines that the target communication mode of the vehicle wireless terminal is Bluetooth Low Energy mode, and controls the Bluetooth module of the vehicle wireless terminal to enter the low-power working mode.

[0084] For example, wake-up commands may include remote vehicle control commands and entry unlock commands, which can be issued by the user through an electronic device (such as a smartphone) bound to the vehicle's wireless terminal. The vehicle's ignition status can be determined by the ignition switch position; if the ignition switch is ON, the vehicle is considered to be running, and if the ignition switch is OFF, the vehicle is considered to be off.

[0085] If the vehicle is off and no wake-up command has been received, it can be determined that the vehicle is stationary and the user has no intention of using the vehicle. In this case, to avoid wasting energy, the onboard wireless terminal and tire pressure sensor can be controlled to enter a low-power mode, and tire information transmission can be stopped.

[0086] S402, the vehicle wireless terminal sends a communication mode command to the tire pressure sensor. The target communication mode corresponding to the communication mode command is Bluetooth Low Energy mode.

[0087] Specifically, the vehicle-mounted wireless terminal sends communication mode commands to the tire pressure sensor via the Bluetooth module in the vehicle-mounted wireless terminal; the low-power Bluetooth mode does not allow the tire pressure sensor to send tire pressure information.

[0088] S403, in response to a communication mode command received from the vehicle's wireless terminal, the tire pressure sensor controls its Bluetooth module to enter a low-power operating mode.

[0089] For example, the tire pressure sensor can receive communication mode commands sent by the vehicle's wireless terminal via its own Bluetooth module. In this way, the communication mode commands can be used to ensure that the vehicle's wireless terminal and the tire pressure sensor enter the same communication mode, thus ensuring smooth communication.

[0090] With the above technical solution, when the vehicle is stationary and the user has no intention of using the vehicle, the vehicle-mounted wireless terminal and tire pressure sensor can be controlled to enter a low-power mode and not transmit tire pressure information, so as to avoid energy waste and extend the device's usage time.

[0091] Figure 5 A signaling interaction diagram between an onboard wireless terminal and a tire pressure sensor is shown in another embodiment of the vehicle tire pressure detection method provided in this disclosure. Figure 5 As shown, the vehicle tire pressure detection method may include steps S501 to S505.

[0092] S501, if the vehicle is in a turned-off state and receives a wake-up command, or if the vehicle is started, the vehicle wireless terminal determines that the target communication mode of the vehicle wireless terminal is the normal Bluetooth mode, and controls the Bluetooth module of the vehicle wireless terminal to enter the normal working mode.

[0093] For example, if the ignition switch changes from OFF to ON, it can be determined that the vehicle is ignited. If the vehicle is off and a wake-up command is received, or if the vehicle is ignited, it can be determined that the user intends to use the vehicle, and the vehicle has not yet started. To facilitate rapid information transmission, the in-vehicle wireless terminal and tire pressure sensor can be controlled to enter normal Bluetooth mode.

[0094] S502, the vehicle wireless terminal sends a communication mode command to the tire pressure sensor, and the target communication mode corresponding to the communication mode command is the regular Bluetooth mode.

[0095] The vehicle-mounted wireless terminal can send communication mode commands to the tire pressure sensor via the Bluetooth module in the vehicle-mounted wireless terminal; the regular Bluetooth mode allows the tire pressure sensor to send tire pressure information.

[0096] S503, the tire pressure sensor responds to the communication mode command sent by the vehicle wireless terminal and controls the Bluetooth module of the tire pressure sensor to enter the normal working mode.

[0097] For example, the tire pressure sensor can receive communication mode commands sent by the vehicle's wireless terminal via its own Bluetooth module. In this way, the communication mode commands can be used to ensure that the vehicle's wireless terminal and the tire pressure sensor enter the same communication mode, thus ensuring smooth communication.

[0098] S504, the tire pressure sensor sends tire pressure information to the vehicle's wireless terminal via the tire pressure sensor's Bluetooth module.

[0099] S505: If the Bluetooth module of the vehicle wireless terminal receives tire pressure information sent by the tire pressure sensor, the vehicle wireless terminal will determine whether there is any abnormality in the vehicle's tires based on the tire pressure information.

[0100] With the above technical solution, when the user intends to use the vehicle but the vehicle has not yet started, the vehicle wireless terminal and tire pressure sensor can be controlled to enter the normal Bluetooth mode to transmit tire pressure information through the Bluetooth modules at both ends. This allows the vehicle wireless terminal to quickly determine whether the vehicle tires are abnormal, thus ensuring the safety of driving the vehicle.

[0101] Figure 6 A signaling interaction diagram between an onboard wireless terminal and a tire pressure sensor is shown in another embodiment of the vehicle tire pressure detection method provided in this disclosure. Figure 6 As shown, the vehicle tire pressure detection method may include steps S601 to S605.

[0102] S601, if the vehicle speed is greater than the vehicle speed threshold, the vehicle wireless terminal determines that the target communication mode of the vehicle wireless terminal is the radio frequency communication mode, and controls the radio frequency module of the vehicle wireless terminal to turn on and the Bluetooth module to enter the low power operation mode.

[0103] As mentioned above, the radio frequency (RF) module consumes less power than the Bluetooth module. However, its efficiency is lower when the vehicle speed is below a certain threshold, resulting in longer intervals between data transmissions. At speeds above the threshold, the RF module's efficiency increases rapidly, allowing for shorter intervals between data transmissions. Therefore, the RF module of the in-vehicle wireless terminal can be activated, and the Bluetooth module can be controlled to enter a low-power operating mode to reduce energy consumption during data transmission.

[0104] The vehicle speed threshold can be preset, for example, to 30 km / h. If the detected vehicle speed is 32 km / h, then the target communication mode of the vehicle-mounted wireless terminal can be determined to be radio frequency communication mode.

[0105] The radio frequency module in the communication module of the vehicle wireless terminal is used to receive information, while the radio frequency module used to send information can be located in the tire pressure sensor. Therefore, the transmission of communication mode commands can be achieved by controlling the Bluetooth modules of the vehicle wireless terminal and the tire pressure sensor to enter a low-power working mode.

[0106] S602, the vehicle-mounted wireless terminal sends a communication mode command to the tire pressure sensor. The target communication mode corresponding to the communication mode command is the radio frequency communication mode.

[0107] Among them, the vehicle-mounted wireless terminal sends communication mode commands to the tire pressure sensor through the Bluetooth module in the vehicle-mounted wireless terminal; the radio frequency communication mode allows the tire pressure sensor to send tire pressure information.

[0108] S603, in response to the communication mode command received from the vehicle wireless terminal, controls the RF module of the tire pressure sensor to turn on and the Bluetooth module to enter low power operation mode.

[0109] For example, the tire pressure sensor can receive communication mode commands sent by the vehicle's wireless terminal via its own Bluetooth module. In this way, the communication mode commands can be used to ensure that the vehicle's wireless terminal and the tire pressure sensor enter the same communication mode, thus ensuring smooth communication.

[0110] S604, the tire pressure sensor sends tire pressure information to the vehicle wireless terminal through the tire pressure sensor's radio frequency module.

[0111] S605, if the radio frequency module of the vehicle wireless terminal receives tire pressure information sent by the tire pressure sensor, the vehicle wireless terminal will determine whether there is any abnormality in the vehicle tires based on the tire pressure information.

[0112] Using the above technical solution, if the vehicle speed exceeds a speed threshold, the onboard wireless terminal and tire pressure sensor can be controlled to enter radio frequency communication mode to transmit tire pressure information through the radio frequency modules at both ends. This reduces energy consumption during communication and allows the onboard wireless terminal to quickly determine if there are any abnormalities in the vehicle's tires, thereby ensuring driving safety.

[0113] Optionally, the vehicle tire pressure detection method provided in this disclosure may further include:

[0114] If an abnormality is found in the vehicle's tires, the vehicle's location information is obtained.

[0115] The vehicle location information, tire pressure information, and tire pressure abnormality warning information are sent to the cloud.

[0116] For example, tire pressure information may include tire pressure and tire temperature values. If the tire pressure exceeds a preset tire pressure threshold range, or the tire temperature exceeds a preset tire temperature threshold range, it can be determined that there is an abnormality in the vehicle's tires. Vehicle location information can be obtained through a positioning system pre-set on the vehicle, where the positioning system can be GNSS (Global Navigation Satellite System) or GPS (Global Positioning System).

[0117] The system sends vehicle location information, tire pressure information, and abnormal tire pressure alerts to the cloud. This allows the cloud to send information about abnormal tire pressure to the vehicle owner's smart device, enabling them to be aware of the problem promptly. It also sends the information to the nearest roadside assistance team for quick resolution of the tire issue. This ensures vehicle safety.

[0118] Based on the same inventive concept, this disclosure also provides a first vehicle tire pressure detection device, which is applied to an in-vehicle wireless terminal. Figure 7 This is a block diagram illustrating a first vehicle tire pressure monitoring device 700 according to an exemplary embodiment. (Refer to...) Figure 7 The first vehicle tire pressure monitoring device 700 may include:

[0119] The first control module 701 is used to determine the target communication mode of the vehicle wireless terminal according to the vehicle status, and control the vehicle wireless terminal to enter the target communication mode.

[0120] The first transmitting module 702 is used to send a communication mode command to the tire pressure sensor, wherein the communication mode command is used to control the tire pressure sensor to enter the target communication mode.

[0121] The determination module 703 is used to determine whether there is an abnormality in the vehicle tires based on the tire pressure information received from the tire pressure sensor.

[0122] The above technical solution determines the target communication mode of the vehicle-mounted wireless terminal based on the vehicle's status and controls the terminal to enter that mode. A communication mode command is sent to the tire pressure sensor, controlling it to enter the target mode. This adapts the communication mode of the wireless terminal and the tire pressure sensor to the vehicle's actual condition, reducing energy consumption and extending device lifespan. If tire pressure information is received from the sensor, it determines whether there are any abnormalities in the tires. This allows the wireless terminal to identify tire abnormalities, thus ensuring driving safety.

[0123] Optionally, the first control module 701 includes:

[0124] The first control submodule is used to determine that the target communication mode of the vehicle wireless terminal is low-power Bluetooth mode if the vehicle is in a turned-off state and no wake-up command is received, and to control the Bluetooth module of the vehicle wireless terminal to enter the low-power working mode.

[0125] Optionally, the first control module 701 includes:

[0126] The second control submodule is used to determine that the target communication mode of the vehicle wireless terminal is the normal Bluetooth mode if the vehicle is in a turned-off state and receives a wake-up command, or if the vehicle is started, and to control the Bluetooth module of the vehicle wireless terminal to enter the normal working mode.

[0127] Wherein, when the target communication mode is the standard Bluetooth mode, the determining module 703 is used to receive the tire pressure information sent by the tire pressure sensor in the following manner:

[0128] The Bluetooth module receives tire pressure information sent by the tire pressure sensor.

[0129] Optionally, the first control module 701 includes:

[0130] The third control submodule is used to determine that the target communication mode of the vehicle wireless terminal is radio frequency communication mode if the vehicle speed is greater than the vehicle speed threshold, and to control the radio frequency module of the vehicle wireless terminal to turn on and the Bluetooth module to enter the low power operation mode.

[0131] Wherein, when the target communication mode is radio frequency communication mode, the determining module 703 is used to receive the tire pressure information sent by the tire pressure sensor in the following manner:

[0132] The radio frequency module receives tire pressure information sent by the tire pressure sensor.

[0133] The first sending module 702 is used to send a communication mode command to the tire pressure sensor in the following manner:

[0134] The Bluetooth module sends a communication mode command to the tire pressure sensor.

[0135] Optionally, the first vehicle tire pressure monitoring device 700 further includes:

[0136] The acquisition module is used to acquire vehicle location information if it is determined that the vehicle tires are abnormal.

[0137] The second sending module is used to send the vehicle location information, the tire pressure information, and the tire pressure abnormality warning information to the cloud.

[0138] Based on the same inventive concept, this disclosure also provides a second vehicle tire pressure detection device, applied to a tire pressure sensor. Figure 8 This is a block diagram illustrating a second vehicle tire pressure monitoring device 800 according to an exemplary embodiment. (Refer to...) Figure 8 The second vehicle tire pressure monitoring device 800 may include:

[0139] The second control module 801 is used to respond to a communication mode command sent by the vehicle-mounted wireless terminal and enter the target communication mode corresponding to the communication mode command.

[0140] The third transmitting module 802 is used to transmit tire pressure information to the vehicle wireless terminal when the target communication mode allows the tire pressure sensor to transmit tire pressure information.

[0141] The above technical solution determines the target communication mode of the vehicle-mounted wireless terminal based on the vehicle's status and controls the terminal to enter that mode. A communication mode command is sent to the tire pressure sensor, controlling it to enter the target mode. This adapts the communication mode of the wireless terminal and the tire pressure sensor to the vehicle's actual condition, reducing energy consumption and extending device lifespan. If tire pressure information is received from the sensor, it determines whether there are any abnormalities in the tires. This allows the wireless terminal to identify tire abnormalities, thus ensuring driving safety.

[0142] Optionally, the target communication mode corresponding to the communication mode instruction is Bluetooth Low Energy mode, which does not allow the tire pressure sensor to send the tire pressure information.

[0143] The second control module 801 is used to enter the target communication mode corresponding to the communication mode command in the following manner:
