[0032] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0033] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0034] Before introducing a vehicle control method provided by an embodiment of the present disclosure, the scheme used in the relevant scenario is first introduced. Generally, when using RF radio frequency technology to detect tire pressure, an RF Bluetooth receiving device needs to be installed independently, and the relevant tire pressure functions are integrated in the Bluetooth receiving device. In this way, there are multiple Bluetooth receiving devices on the vehicle, such as a Bluetooth digital key, a car Bluetooth module, and an RF Bluetooth receiving device, which can realize the reuse of a Bluetooth receiving module and save a receiving device.

[0035] However, the tire pressure RF Bluetooth receiver shares a Bluetooth receiver module with the vehicle computer or digital key, which may occupy the system RAM (Random-Access Memory) and flash (Flash EEPROM Memory) resources. The tire pressure self-positioning learning function occupies a large amount of system resources, which not only increases the selection requirements for the Bluetooth receiving module and increases the selection cost, but also for products that have already been selected, there may be insufficient remaining RAM and flash resources and they cannot be used directly. In addition, adding a self-positioning learning function may be limited by the code space and cannot be integrated, resulting in it being impossible to implement.

[0036] Figure 1 is a flow chart of a vehicle control method according to an exemplary embodiment. The method can be applied to a vehicle, for example, Figure 2 As shown, the vehicle 100 is equipped with, for example, four tire pressure sensors 1001. It is understood that the four tire pressure sensors 1001 are only exemplary. The number of tire pressure sensors equipped on the vehicle 100 is consistent with the number of tires. Figure 2As shown, the tire pressure sensor 1001 is configured with a battery, a crystal oscillator, an acceleration sensor, a temperature sensor, an air pressure sensor, a SOC (System on Chip), a Bluetooth communication module and an RF communication module. Among them, the SOC is configured with a PMIC (Power Management IC), a memory 1 and an MCU (Micro controller Unit), the Bluetooth communication module can be connected to the anchor point of the Bluetooth module through the Bluetooth antenna, and the RF communication module can be connected to other devices through the RF antenna.

[0037] The Bluetooth key module configured in the vehicle 100 can be connected to the tire pressure sensor through the Bluetooth antenna. The Bluetooth key module can be configured with a Bluetooth key algorithm software library and a tire pressure algorithm software library at the same time. The Bluetooth key algorithm software library can realize the Bluetooth key function, and the tire pressure algorithm software library can realize the tire pressure function. At the same time, the Bluetooth key module is also configured with a RAM for running algorithms and programs and a Flash for storing software programs and data.

[0038] The Bluetooth key module in the vehicle 100 is connected to the wheel speed sensor and the vehicle system through the CAN (Controller Area Network) bus. The vehicle system can be configured with a vehicle-side account system and a memory 2, and then the vehicle-side account system can store the logged-in user account information in the memory 2. The vehicle system can be connected to a display screen, and then display tire pressure information, for example, on the display screen. At the same time, the vehicle system is connected to a remote communication terminal. Figure 1 As shown, the following steps are included.

[0039] In step S11, according to the driving state information of the vehicle, a target tire pressure function enabled by the tire pressure monitoring function configured by the Bluetooth key module and a target key function enabled by the Bluetooth key function are determined; Among them, the tire pressure monitoring function can realize tire pressure functions including data analysis, tire pressure learning self-positioning, tire pressure display, tire pressure alarm, NVM (Node Version Manager), diagnosis, etc. through the tire pressure algorithm library. The Bluetooth key function can realize software functions including Bluetooth connection (including broadcasting and monitoring), ICCOA (Intelligent Car Connectivity Open Alliance), CCC (Car Connectivity Consortium), ICCE (Intelligent Car Connectivity Industry Ecosystem Alliance), and other digital key protocols and unlocking and locking algorithms through the Bluetooth key algorithm software library.

[0040] In the disclosed embodiment, the driving status information of the vehicle can be received. The driving status information may include vehicle speed, engine status, door switch status, etc. Based on the driving status information, the current vehicle usage scenario and safety requirements can be intelligently judged. Then, according to the preset rules or algorithms, the target tire pressure function and target key function that need to be enabled by the Bluetooth key module are analyzed and determined. The target tire pressure function may include real-time tire pressure monitoring, abnormal tire pressure alarm, etc.; and the target key function may include door unlocking, vehicle starting, remote control, etc.

[0041] For example, suppose the vehicle is traveling on a highway at a fast and stable speed. At this time, the vehicle speed information is received and it is determined that the vehicle is in a high-speed driving state. In order to ensure driving safety, the target tire pressure function can be enabled as a real-time monitoring function for tire pressure and tire temperature, so as to promptly detect and handle abnormal tire pressure. At the same time, since the vehicle is driving, the target key function can be turned on only for Bluetooth, and key functions such as door unlocking may not be enabled to avoid potential safety risks and reduce computing power usage.

[0042] In another scenario, if the vehicle is parked in a parking lot and the engine is turned off, the vehicle may be judged to be stationary and safe based on the door switch status and engine status information. At this time, the target key function can be enabled, including door unlocking, remote start and other key functions, to facilitate the owner to operate the vehicle. The target tire pressure function only includes the real-time monitoring function of tire temperature.

[0043] In step S12, according to the target tire pressure function, the tire pressure sensor is controlled to perform tire pressure information sampling, and the key function is performed according to the target key function.

[0044] Among them, the tire pressure sensor can be a tire pressure Bluetooth sensor, and the tire pressure Bluetooth sensor can be configured with a sensor module, SOC, battery and communication device, wherein the sensor module can include, for example, a temperature sensor for measuring the temperature value inside the tire, an air pressure sensor for measuring the air pressure value inside the tire (relative to atmospheric pressure), and an acceleration sensor for measuring the acceleration value inside the tire.

[0045] The SOC may include an MCU, a PMIC and a memory, which are used to provide working power to the tire pressure sensor. The communication device may include a Bluetooth communication module and an RF communication module. The Bluetooth communication module may communicate with the Bluetooth key modules on the vehicle side and the mobile phone side through the Bluetooth antenna. The RF communication module may be connected to the activation device on the production line and the maintenance line through the RF antenna, thereby activating the tire pressure sensor through the activation device.

[0046] In the disclosed embodiment, according to the determined target tire pressure function, an instruction is sent to the tire pressure sensor to control it to perform tire pressure information sampling. After receiving the instruction, the tire pressure sensor will start to collect the tire pressure information of the current tire and send this information back to the system for processing and analysis. At the same time, corresponding key operations can also be performed according to the target key function. For example, if the target key function is to unlock the door, the function of receiving the unlock instruction in the Bluetooth key module can be enabled, and then when the unlock instruction sent by the Bluetooth key is received, the unlock instruction is sent to the vehicle through the Bluetooth key module to automatically unlock the door; if the target key function is to remotely start the vehicle, then when the remote start vehicle instruction sent by the Bluetooth key is received, a start instruction can be sent to the vehicle to start the vehicle engine.

[0047] Let's continue with the example of a vehicle driving on a highway. It has been determined that the tire pressure real-time monitoring function is enabled. Therefore, a command is sent to the tire pressure sensor to request it to start collecting tire pressure information. After receiving the command, the tire pressure sensor will immediately start working and collect tire pressure information such as tire pressure, tire temperature and alarm function according to the preset sampling frequency, and send the tire pressure information back to the system for processing at a certain frequency. If the tire pressure is found to be abnormal (such as too low or too high), an alarm message will be sent immediately to the owner to remind him to pay attention to driving safety. At this time, the target key function enabled is only to connect to the Bluetooth key with the Bluetooth key, that is, turn on Bluetooth to determine that the vehicle has a Bluetooth key.

[0048] In another scenario, if the vehicle is parked in a parking lot, the target key function enabled is door unlocking, and the target tire pressure function enabled is only the alarm function, and then when a remote door unlocking command is received, an unlocking command is sent to the vehicle. At this time, an unlocking request is sent to the system through a mobile phone or other Bluetooth device to verify the owner's identity and send an unlocking command to the vehicle, so that the door is automatically unlocked.

[0049] The above technical solution determines the target tire pressure function enabled by the tire pressure monitoring function configured by the Bluetooth key module and the target key function enabled by the Bluetooth key function according to the driving status information of the vehicle; controls the tire pressure sensor to perform tire pressure information sampling according to the target tire pressure function, and performs the key function according to the target key function. It can realize the system integration fusion based on tire pressure sensor and Bluetooth key, switch functions in different states, and realize time division multiplexing, which can not only reduce costs, but also avoid the problem of insufficient computing resources caused by running multiple high-energy consumption and high-computation tasks at the same time.

[0050] Alternatively, see Figure 3 As shown, in step S11, the step of determining the target tire pressure function enabled by the tire pressure monitoring function configured by the Bluetooth key module and the target key function enabled by the Bluetooth key function according to the driving state information of the vehicle includes: In step S111, in response to a change in the vehicle state of the vehicle, the driving state information of the vehicle is acquired; Among them, the change in vehicle status refers to the vehicle changing from one status to another based on driving or user operation. If the vehicle status has not changed, the current target tire pressure function and target key function are maintained. If the vehicle status has changed, it is necessary to re-acquire the vehicle's driving status information.

[0051] In the disclosed embodiment, the vehicle status information may include the power mode of the vehicle, and the power mode may be, for example, that the vehicle is in a power-off state, or that the vehicle is in an Aweak / ACC (Adaptive Cruise Control) state, or that the vehicle is in a running state, or that the vehicle is in an Aweak / OFF state. The vehicle status information may also include the vehicle speed and gear position, for example, the vehicle speed is 0, or the vehicle speed is less than a preset vehicle speed, or the vehicle speed is greater than or equal to a preset vehicle speed, and the gear position may be that the vehicle is in P (Park), the vehicle is in D (Drive), the vehicle is in R (Reverse), or the vehicle is in N (Neutral).

[0052] In the disclosed embodiment, the driving state of the vehicle is monitored in real time through built-in sensors or connected vehicle networks (such as CAN bus). When the vehicle state changes (such as speed change, braking, acceleration, etc.), the change information is immediately responded to and captured, including driving state information such as vehicle speed, acceleration, braking state, engine state, etc. For example, the power mode can be obtained by obtaining the state of the relay in the vehicle electrical box, the vehicle speed can be obtained from the vehicle speed sensor or the instrument cluster or the body control module or the cockpit domain controller through the bus, and the gear position can be obtained through the transmission controller.

[0053] In step S112, according to the driving state information of the vehicle, a target tire pressure function enabled by the tire pressure monitoring function configured by the Bluetooth key module and a target key function enabled by the Bluetooth key function are determined.

[0054] The disclosed embodiment can analyze the driving status information according to a preset algorithm or rule, and determine the target tire pressure function and target key function enabled by the Bluetooth key module accordingly. For example, when the vehicle is in a low-speed driving or parking state, the real-time requirements of tire pressure monitoring are reduced, and the basic tire pressure monitoring function is maintained; at the same time, in order to improve the user experience, convenient key functions such as window control by key can be enabled. When the vehicle is in a high-speed driving state, the real-time and accuracy of tire pressure monitoring are enhanced to ensure driving safety, and some key functions that may distract the driver's attention may be restricted or disabled.

[0055] The above technical solution can intelligently determine and enable the target tire pressure function and target key function of the Bluetooth key module according to the real-time driving status information of the vehicle, reduce the computing power requirements of the Bluetooth key module, and thus realize intelligent management and control of the vehicle. Compared with the traditional fixed function activation method, this dynamic adjustment method can better adapt to different driving conditions and improve the overall performance of the system and user experience.

[0056] Optionally, before obtaining the driving state information of the vehicle in response to a change in the vehicle state, the method further includes: If the driving state of the vehicle enters the parking and locking state, the timing is started; In the disclosed embodiment, the parking lock state may be a state where the vehicle speed is 0, and thus the parking lock state may be entered when the vehicle speed is reduced, for example, during driving, the vehicle starts braking until the vehicle speed is 0. The parking lock state may be entered when the vehicle starts braking, or when the vehicle speed is already 0. Therefore, the timer may be triggered to start timing when the brake pedal of the vehicle is pressed, or when the vehicle speed is reduced to 0.

[0057] According to the timing duration of the timing and a preset duration threshold, it is determined that the vehicle state of the vehicle has changed.

[0058] In the disclosed embodiment, during the operation of the timer, the timing duration is continuously checked and compared with a preset duration threshold. The preset duration threshold can be set according to the vehicle usage habits, safety requirements, and energy saving considerations. If the timing duration exceeds the preset duration threshold, it can be determined that the state of the vehicle has changed from the original parking and locking state to a "long-term unused" or "dormant" state.

[0059] For example, when it is detected that the timing duration has exceeded a preset duration threshold T, for example, the preset duration threshold T can be 10 minutes, or 15 minutes, which can be defined, it can be determined that the vehicle state has changed and entered the stationary mode.

[0060] In this way, setting the timing duration and the preset duration threshold T as hysteresis can avoid repeated switching between static and running modes in the process of driving for situations such as temporary braking to stop, waiting for a red light, etc.

[0061] Optionally, the method further comprises: When it is determined that the vehicle state of the vehicle has not changed, the target tire pressure function being enabled and the target key function being enabled are maintained.

[0062] In an embodiment of the present disclosure, when it is determined that the vehicle state of the vehicle has not changed, for example, when it is determined that the timing duration has not reached a preset duration threshold, or when it is determined that the vehicle is in a parked and locked state, or when it is determined that the vehicle is in an unlocked and parked state, the currently enabled target tire pressure function and the enabled target key function are maintained.

[0063] For example, since the vehicle was in a driving state before parking, the target tire pressure functions enabled in the driving state are tire temperature monitoring, tire pressure monitoring and real-time reporting of information, and the target key function enabled is maintaining a Bluetooth connection with the Bluetooth key. Therefore, when it is determined that the timing duration has not reached the preset duration threshold, the target tire pressure functions such as tire temperature monitoring, tire pressure monitoring and real-time reporting of information and the target key functions such as maintaining a Bluetooth connection with the Bluetooth key are kept enabled.

[0064] Optionally, the vehicle status includes at least one of the following: a parking locked state, an unlocked state, a driving state, and a dormant parking state.

[0065] Among them, the parking lock state can be, for example, a locked parking state, for example, the power mode of the vehicle is in a power-off state, the vehicle speed is reduced to 0, and the gear is in P gear. It can also be a locked state in which the power mode of the vehicle is in a running state, the vehicle speed is 0, and the gear is in D gear, or R gear or N gear. The unlocked state can be a state in which the parking lock state is switched to a state in which the power mode is awake and adaptive cruise, or a state in which the driving state is switched to an unlocked state in which the engine is turned off and parked. The driving state can usually be determined by the vehicle speed, for example, the vehicle speed is greater than 0. The dormant parking state is that the power mode of the vehicle is in a power-off state, the vehicle speed is 0, the gear is in P gear, and the vehicle is always in a low-power dormant state.

[0066] See also Figure 4In the illustrated embodiment, the vehicle status can also be divided into a stationary locked state, a stationary unlocked state, a moving driving state, a stationary red light state, a stationary driving state and a stationary parking state.

[0067] The stationary locked vehicle state corresponds to the vehicle power mode being in the off state, the vehicle speed being 0, and the gear being P. At this time, the enabled target tire pressure function may be only for abnormal monitoring, and all Bluetooth key functions may be used as enabled target key functions.

[0068] When receiving a command to unlock the vehicle, such as a Bluetooth key, or a physical key or remote control key, the vehicle state can be confirmed to have changed, and then switched to a stationary unlocked state, where the vehicle power mode corresponding to the stationary unlocked state can be an awake adaptive cruise state, a vehicle speed of 0, and a gear position of P. At this time, the enabled target tire pressure function can be only abnormality monitoring, and all Bluetooth key functions can still be used as enabled target key functions.

[0069] Further, when the vehicle is started and the vehicle state is switched to the sports driving state, the power mode of the vehicle corresponding to the sports driving state is the power-on state, the vehicle speed is greater than the preset vehicle speed threshold, for example, the preset vehicle speed threshold may be 30 kilometers per hour, and the gear is D gear or R gear. At this time, the enabled target tire pressure function may include tire temperature monitoring, tire pressure monitoring and real-time reporting information, and the Bluetooth connection with the Bluetooth key is used as the enabled target key function.

[0070] Furthermore, during the vehicle braking process or after the vehicle stops, it can be confirmed that the vehicle state has changed, and then switched to the stationary red light state. The stationary red light state corresponds to the vehicle power mode being the power-on state, the vehicle speed being less than or equal to the preset vehicle speed threshold, for example, the preset vehicle speed threshold may be 30 kilometers per hour, and the time duration being less than the preset time threshold, for example, the preset time threshold may be 10 minutes, and the gear is D gear, R gear, or N gear. At this time, the enabled target tire pressure function can maintain tire temperature monitoring, tire pressure monitoring, and real-time reporting information, and continue to connect to the Bluetooth key through Bluetooth as the enabled target key function.

[0071] Furthermore, when the vehicle starts moving again, it can be determined that the vehicle state changes to a moving driving state, and the enabled target tire pressure function can maintain tire temperature monitoring, tire pressure monitoring and real-time reporting of information, and continue to connect to the Bluetooth key as the enabled target key function.

[0072] Further, after the vehicle is braked to a stop, it can be determined that the vehicle state has changed, and the vehicle state is a stationary driving state, and the stationary driving state corresponds to the vehicle power mode being a power-on state, the vehicle speed being 0, and the gear being D gear, R gear, or N gear. At this time, the enabled target tire pressure function can remain tire temperature monitoring, tire pressure monitoring, and real-time reporting information, and continue to use Bluetooth connection with the Bluetooth key as the enabled target key function. However, the frequency of tire temperature monitoring, tire pressure monitoring, and real-time reporting information can be reduced.

[0073] Furthermore, if the gear is switched to P or the timer duration is greater than the preset time threshold, the vehicle state is switched to a stationary parking state, and the stationary parking state corresponds to the vehicle power mode being the wake-up power-off state, the vehicle speed being 0, and the gear being P. At this time, the enabled target tire pressure function may only be used for abnormality monitoring, and all Bluetooth key functions may still be used as enabled target key functions.

[0074] Optionally, controlling the tire pressure sensor to perform tire pressure information sampling according to the target tire pressure function includes: determining, according to the target tire pressure function, an operating mode of the tire pressure sensor on the vehicle; In the disclosed embodiments, different tire pressure functions, such as real-time monitoring, abnormality alarm, regular self-inspection, etc., may require the tire pressure sensor to perform sampling at different frequencies and accuracies.

[0075] The working modes of the tire pressure sensor can include normal monitoring mode, low power mode, alarm mode, etc. Each mode corresponds to a different sampling frequency and data processing method. In this way, the working mode of the tire pressure sensor can be determined according to the vehicle status.

[0076] For example, if the vehicle is in a stationary unlocked state, the target tire pressure function is to monitor the tire pressure in real time and issue an alarm when the pressure is abnormal, then the corresponding tire pressure sensor working mode can be low power mode. When the vehicle starts and starts driving, the target tire pressure function can be to monitor the tire pressure and temperature in real time and report them in real time, and the corresponding tire pressure sensor working mode can be normal monitoring mode.

[0077] According to the working mode, the tire pressure sensor is controlled to perform tire pressure information sampling.

[0078] In the implementation of the present disclosure, after determining the working mode of the tire pressure sensor, a command is sent to the tire pressure sensor via a wireless signal such as Bluetooth, instructing it to perform sampling at a specified frequency and accuracy. After receiving the command, the tire pressure sensor starts the internal pressure sensor and temperature sensor to convert the collected air pressure and temperature data into electrical signals. After the electrical signal is processed, it is sent to the receiver in the car through the wireless transmission module, and finally the tire pressure and temperature information is displayed on the dashboard.

[0079] For example, when the tire pressure sensor is in normal monitoring mode, it can collect tire pressure data and temperature data every 30 seconds. If the air pressure of a tire suddenly drops, the tire pressure sensor will immediately detect the change, send the tire pressure data in real time, and trigger the alarm mechanism. The alarm information is sent to the receiver in the car via a wireless signal, and the driver is reminded of the abnormal tire pressure visually and audibly on the dashboard. In low power mode, tire pressure data can be collected and saved locally. If the air pressure of a tire suddenly drops, the tire pressure sensor will immediately detect the change and trigger the sending of tire pressure data, and trigger the alarm mechanism.

[0080] In this way, the working mode of the tire pressure sensor is determined according to the target tire pressure function, and the tire pressure sensor is controlled to perform tire pressure information sampling according to the working mode, which can ensure that the tire pressure monitoring system can accurately and timely reflect the tire pressure status and improve driving safety.

[0081] Optionally, controlling the tire pressure sensor to perform tire pressure information sampling according to the working mode includes: Determining a target operating frequency of a sensor function configured in the tire pressure sensor according to the operating mode, wherein the same function configured in the tire pressure sensor has different operating frequencies in different operating modes; In the disclosed embodiment, the control unit in the tire pressure monitoring system (TPMS) determines the function to be performed by the tire pressure sensor and its corresponding operating frequency according to the determined operating mode of the tire pressure sensor. For example, in the low power consumption mode, a lower sampling frequency may be set to save energy and reduce sensor wear; while in the normal monitoring mode, the sampling frequency may be increased to more accurately monitor tire pressure changes.

[0082] For example, the sampling frequency in the running mode is greater than the sampling frequency in the positioning mode, the sampling frequency in the positioning mode is greater than the sampling frequency in the static mode, and the sampling frequency in the static mode may be greater than or equal to the sampling frequency in the sleep mode.

[0083] In the embodiment of the present disclosure, it is assumed that the vehicle is traveling at a constant speed on a highway. At this time, the tire pressure sensor may be in a normal monitoring mode, and its operating frequency is set to collect tire pressure data and temperature data every 5 seconds. However, when the vehicle enters a stationary mode, the sampling frequency of the tire pressure sensor is reduced to once every 60 seconds to reduce energy consumption.

[0084] The tire pressure sensor is interacted with by the anchor point of the Bluetooth key, so that the tire pressure sensor performs tire pressure information sampling according to the target operating frequency.

[0085] Among them, the anchor point of the Bluetooth key is the access point of Bluetooth communication. The Bluetooth key anchor point here can not only be used to establish Bluetooth connection between the vehicle's on-board system and mobile phones, remote control keys, etc., but also to establish a connection between the tire pressure monitoring system and the tire pressure sensor. Send instructions to the tire pressure sensor through the anchor point of the Bluetooth key, including the set working frequency, sampling request, etc. After receiving the instruction, the tire pressure sensor performs tire pressure information sampling at the specified frequency, and sends the collected data back to the control unit via Bluetooth or other wireless methods.

[0086] In the disclosed embodiment, the tire pressure sensor can establish a Bluetooth connection with the main anchor point of the Bluetooth key, that is, multiple tire pressure sensors are connected to a determined main anchor point, or each tire pressure sensor can establish a Bluetooth connection with an anchor point. Among them, the anchor points of the Bluetooth key can be set at the four corners of the vehicle, so each tire pressure sensor can establish a Bluetooth connection with the nearest anchor point of the Bluetooth key. In this way, not only can the Bluetooth receiving devices configured on the vehicle be reduced, the anchor points of the Bluetooth key can be shared, but also the Bluetooth anchor points deployed on the vehicle can be reduced, saving costs.

[0087] Optionally, the working mode includes at least one of the following: sleep mode, stationary mode, running mode, and positioning mode.

[0088] Among them, sleep mode is a low-power state of TPMS, which can save power. In sleep mode, the tire pressure sensor can reduce or stop data sampling and transmission until a wake-up signal is received.

[0089] The stationary mode is when the vehicle is stationary but the engine is still running. If the tire pressure is lower than the low pressure warning threshold, or the tire pressure is higher than the high pressure warning threshold, you can switch to the stationary mode. In this mode, the TPMS may reduce the data sampling frequency, but still maintain basic monitoring of tire pressure.

[0090] The operating mode is the normal working state of the TPMS. When the vehicle is driving, it enters this mode. In the operating mode, the tire pressure sensor will collect and transmit tire pressure data at a preset frequency to ensure that the driver can understand the tire status in real time.

[0091] The positioning mode is used during the initial installation or re-setting of the TPMS to ensure that each tire pressure sensor can be correctly identified and matched to its corresponding tire. In this mode, the positioning and calibration of the sensor can be completed.

[0092] See also Figure 5In the embodiment shown, in sleep mode, the tire pressure and temperature sampling frequency is 60 seconds, and the RF transmission is not transmitted, thereby reducing power consumption. This mode can be used for vehicle transportation and warehousing. At this time, the vehicle and the tire pressure sensor are not moving, so there is no RF transmission. Among them, the RF transmission is the tire pressure sensor transmitting tire pressure information to the vehicle through the anchor point of the Bluetooth key.

[0093] In stationary mode, the tire pressure and temperature sampling frequency is 60 seconds, and the RF transmission frequency is 60 minutes / packet. The vehicle is also parked in this mode. It can switch from sleep mode to stationary mode when the tire pressure sensor detects abnormal temperature or tire pressure.

[0094] After detecting that the vehicle is in motion, it can switch from static mode to positioning mode. In positioning mode, the tire pressure and temperature sampling frequency is 11.25 seconds, and the RF transmission frequency is 15.5 seconds / packet-22.5 seconds / packet. After continuously monitoring that it is in the running state, it enters PAL (automatic positioning) mode until positioning is completed and switches to running mode.

[0095] In the operating mode, the tire pressure and temperature sampling frequency is 5 seconds, and the RF transmission frequency is 1min / packet. If no movement is detected for a continuous preset time, it can switch to the static state.

[0096] Optionally, controlling the tire pressure sensor to perform tire pressure information sampling according to the target tire pressure function includes: According to the target tire pressure function, calling a first software development kit configured in the Bluetooth key module, the first software development kit being a software development kit corresponding to the tire pressure monitoring function; Among them, the first software development kit (SDK) is a collection of software development tools and library files for tire pressure monitoring function, including API (Application Programming Interface), library functions, sample codes, etc. for tire pressure monitoring function, which is used for software development of tire pressure monitoring function.

[0097] In the disclosed embodiment, the TPMS system calls the SDK of the tire pressure monitoring function according to the target tire pressure function. The SDK is pre-installed in the Bluetooth key module and includes all software tools and library files required to implement the tire pressure monitoring function.

[0098] For example, if the vehicle is traveling long distances at high speeds, and the TPMS monitors the tire pressure in real time, the TPMS system will use "real-time monitoring" as the target tire pressure function and call the SDK of the tire pressure monitoring function in the Bluetooth key module to achieve real-time collection and transmission of tire pressure data.

[0099] The corresponding target software functions are enabled through the first software development kit, and the tire pressure sensor is controlled to perform tire pressure information sampling.

[0100] In the disclosed embodiment, after calling the SDK of the tire pressure monitoring function, the TPMS system uses the API and library functions provided in the SDK to enable the corresponding software functions. These functions may include initialization of the tire pressure sensor, setting of the sampling frequency, data collection and transmission, etc. By calling the SDK, the TPMS system can achieve precise control of the tire pressure sensor to meet specific monitoring requirements.

[0101] In this way, the tire pressure sensor can be flexibly controlled to sample and transmit tire pressure information according to different target tire pressure functions, thereby ensuring the safety and stability of vehicle driving.

[0102] Optionally, executing a key function according to the target key function includes: According to the target key function, calling a second software development kit configured in the Bluetooth key module, where the second software development kit is a software development kit corresponding to the Bluetooth key function; Among them, the second software development kit is a software development kit corresponding to the Bluetooth key function, which includes all software tools and library files required to implement the Bluetooth key function and is used to accelerate the development and integration of the Bluetooth key function.

[0103] In the disclosed embodiment, when the vehicle is in a stopped and locked state, for example, in a scene where the vehicle is parked in a basement, the corresponding second SDK in the Bluetooth key module is called according to the target key function, for example, the Bluetooth connection function is turned on, the positioning function is turned on. This SDK contains all the software tools and library files required to implement the target key function, so that the vehicle can execute the corresponding key function according to the instruction.

[0104] The corresponding target software function is enabled by the second software development kit to execute the key function.

[0105] After calling the second SDK corresponding to the target key function, the vehicle's control unit will use the API and library functions provided in the SDK to enable the corresponding software functions. These functions may include initialization of Bluetooth communication, parsing and execution of instructions, control of vehicle actuators, etc. By calling the SDK and using the API, the vehicle can achieve precise control of the key function, thereby meeting the user's remote control needs.

[0106] For example, when the vehicle is in a stopped and locked state in an underground parking lot, all Bluetooth key functions can be enabled through the second SDK, while only the target tire pressure function of abnormal tire pressure monitoring can be enabled through the first SDK. After the vehicle is unlocked and running, only the Bluetooth connection function with the Bluetooth key can be enabled through the second SDK, while all tire pressure functions such as real-time tire pressure monitoring and tire temperature monitoring can be enabled through the first SDK.

[0107] In this way, the Bluetooth key module is reused. The tire pressure sensor and Bluetooth key can share the Bluetooth key's anchor point and Bluetooth receiving module, and selectively enable different functions according to the actual vehicle status, avoiding the large computing power resource requirements of the Bluetooth receiving module and reducing costs.

[0108] Optionally, the driving status information includes at least one of the following: power mode, vehicle speed, and gear information of the vehicle.

[0109] As can be seen from the above embodiments, the power mode is used to indicate the current power connection state of the vehicle, which may include a power-off state, an adaptive cruise control state, a power-on state, etc. The vehicle speed is used to indicate the current speed of the vehicle. The gear information is the vehicle driving state indicated in the vehicle configuration, such as a transmission or an electronic control system.
