Description

Technical Field

[0001] This application relates to the field of tire pressure monitoring, and more particularly to a sensor protection method, device, storage medium, and electronic device. Background Technology

[0002] Currently, a direct tire pressure monitoring system (TPMS) consists of two parts: a sensor and a receiver. The sensor monitors tire pressure information such as tire pressure and tire temperature, while the receiver reports the tire pressure information sent by the sensor to the central electronic module (CEM), which then performs logical analysis and processing on the tire pressure information.

[0003] Existing sensors cannot be effectively protected during use, have a short lifespan, and need to be replaced regularly, which increases the cost of using TPMS. Summary of the Invention

[0004] The applicant discovered that most sensors in existing TPMS operate for extended periods, which shortens their lifespan. Therefore, by rationally scheduling the sensor's operating time and avoiding prolonged operation, effective protection of the sensor can be achieved, extending its lifespan and reducing the cost of using the TPMS.

[0005] This application provides a sensor protection method, apparatus, storage medium, and electronic device, with the aim of extending the service life of the sensor and reducing the cost of using TPMS.

[0008] Based on the vehicle status, a corresponding control signal is generated; the control signal is used to control the sensor to adjust its own working state; the types of the working state include the sleep state and the wake-up state;

[0009] The control signal is sent to the sensor, triggering the sensor to adjust its own working state; the adjusted working state of the sensor is the same as the vehicle state type.

[0015] Optionally, the control signal may include a shutdown signal and an on signal;

[0016] Based on the vehicle state, corresponding control signals are generated, including:

[0017] If the vehicle is in the sleep state, a shutdown signal is generated; if the vehicle is in the wake-up state, an activation signal is generated.

[0018] Optionally, the control signal is sent to the sensor to trigger the sensor to adjust its own operating state, including:

[0019] When the vehicle is in the sleep state, the shutdown signal is sent to the sensor, triggering the sensor to adjust its own operating state to the sleep state; the sensor stops tire pressure monitoring in the sleep state.

[0020] When the vehicle is in the awakened state, the activation signal is sent to the sensor, triggering the sensor to adjust its working state to the awakened state; the sensor performs tire pressure monitoring in the awakened state.

[0021] Optionally, the control signal is sent to the sensor to trigger the sensor to adjust its own operating state, including:

[0022] The control signal is converted into a low-frequency signal by an antenna pre-installed on the vehicle, and the low-frequency signal is sent to the sensor to trigger the sensor to adjust its own working state; the sensor responds to the low-frequency signal based on an internal process and adjusts its own working state accordingly.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] like Figure 1 The diagram shown is a flowchart of a sensor protection method provided in an embodiment of this application, which can be applied in CEM and includes the following steps.

[0040] S101: Obtain vehicle status.

[0041] Understandably, there are multiple ways to obtain vehicle status. For example, vehicle status can be determined based on signals sent by the user via a mobile device. Alternatively, vehicle status can be determined based on the vehicle's power mode.

[0042] Optionally, the specific implementation process for obtaining the vehicle status includes: obtaining the vehicle's power mode; and determining the vehicle status based on the power mode.

[0043] It should be noted that the method for obtaining the vehicle's power mode is common knowledge in this field and will not be elaborated upon here. The so-called vehicle status is typically used to indicate whether the vehicle is in a working state, that is, to determine whether the vehicle is being used by a user.

[0044] Generally speaking, vehicle status can be categorized into two types: dormant and active. Dormant status indicates that the vehicle is not in use, such as when the user turns off the engine and parks the vehicle, or when the user remotely locks the doors. Active status indicates that the vehicle is in use, such as when the user remotely turns on the lights or air conditioning, when the user is driving the vehicle, or when the user starts the vehicle.

[0045] Optionally, the specific implementation process for determining the vehicle state based on the power mode includes: if the power mode is power-down, then the vehicle state is determined to be in a sleep state; if the power mode is power-on, then the vehicle state is determined to be in a wake-up state.

[0046] S102: Generate corresponding control signals based on vehicle status.

[0047] The control signal is used to control the sensor to adjust its own working state. The sensor's working state can specifically include sleep state and wake-up state. Generally speaking, when the vehicle is in sleep state, the vehicle is not in use. Therefore, the tire pressure monitoring function provided by TPMS does not need to continue to be executed (i.e., CEM no longer performs logical analysis and processing of tire pressure information). By controlling the sensor to enter sleep state, the sensor can be prevented from working for a long time, effectively protecting the sensor, extending the sensor's service life, and reducing the cost of using TPMS.

[0048] It should be noted that the control signals include both off and on signals. Optionally, the specific implementation process for generating the corresponding control signal is based on the vehicle state. See [link to relevant documentation]. Figure 2 The steps shown are explained below.

[0049] S103: Sends a control signal to the sensor, triggering the sensor to adjust its own working state.

[0050] The adjusted sensor's operating state is the same as the vehicle's operating state. That is, if the vehicle is in a dormant state, the adjusted sensor will also be in a dormant state; if the vehicle is in a wake-up state, the adjusted sensor will also be in a wake-up state.

[0051] In this embodiment, if the sensor is in a dormant state, it will stop monitoring tire pressure, that is, it will stop collecting tire pressure information such as tire pressure and tire temperature, and stop sending the collected tire pressure information to the receiver. At this time, the sensor consumes the least amount of energy.

[0052] If the sensor is in the wake-up state, it will perform tire pressure monitoring, that is, the sensor will collect tire pressure information such as tire pressure and tire temperature, and send the collected tire pressure information to the receiver.

[0053] Since the sensor is used to monitor tire pressure information such as tire pressure and tire temperature, it is typically mounted on the wheel and powered by its own battery. The sensor also has wireless signal transmission capabilities to send the real-time tire pressure information it collects to a receiver. Therefore, this embodiment of the application uses wireless communication to send control signals to the sensor to control its operating state.

[0054] Optionally, the specific implementation process of sending the control signal to the sensor to trigger the sensor to adjust its own working state includes: converting the control signal into a low-frequency signal through an antenna pre-installed on the vehicle, and sending the low-frequency signal to the sensor to trigger the sensor to adjust its own working state; the sensor responds to the low-frequency signal based on its internal process and adjusts its own working state.

[0055] To ensure the antenna can successfully receive low-frequency signals from the sensor, it is necessary to ensure that the antenna's installation location is within the sensor's signal reception range. Specifically, regarding the antenna's installation location being within the sensor's signal reception range, please refer to... Figure 3 As shown.

[0056] Generally speaking, the types of antennas shown in the embodiments of this application include, but are not limited to, low-frequency antennas and mobile terminals. Specifically, taking a mobile terminal with low-frequency signal transmission function as an example, when the mobile terminal obtains the vehicle status, it can generate a control signal corresponding to the vehicle status, and then send the control signal to the sensor, triggering the sensor to adjust its own working state based on the control signal so that the adjusted working state is the same as the vehicle status type.

[0057] Furthermore, for sensors with network communication capabilities, the embodiments of this application can also send control signals to the sensor via the cloud. It is understood that other methods of sending control signals to the sensor can also be considered as means that can be implemented by the embodiments of this application, and will not be described in detail here.

[0058] It should be noted that both the on and off signals are specific manifestations of control signals. Therefore, the specific process of sending a control signal to the sensor to trigger the sensor to adjust its own working state can be summarized as follows: Figure 2 The process is shown below.

[0059] Based on the process shown in S101-S103, this embodiment of the application adjusts the working state of the sensor based on the vehicle state so that the adjusted working state is consistent with the vehicle state. This ensures that when the vehicle is in a sleep state, the sensor also enters a sleep state, thereby avoiding the sensor from working for a long time, effectively protecting the sensor, extending the sensor's service life, and reducing the cost of using TPMS.

[0060] like Figure 2 The diagram shown is a flowchart of another sensor protection method provided in this application embodiment, including the following steps.

[0061] S201: Generate corresponding control signals based on vehicle status.

[0062] Specifically, if the vehicle is in a dormant state, a shutdown signal is generated; if the vehicle is in a wake-up state, an activation signal is generated.

[0063] S202: When the vehicle is in sleep mode, a shutdown signal is sent to the sensor, triggering the sensor to adjust its own working state to sleep mode.

[0064] The sensor stops monitoring tire pressure when it is in sleep mode.

[0065] It is understood that the sensor is mounted on the wheel and has wireless communication capabilities. Therefore, in this embodiment, the shut-off signal can be sent to the sensor via wireless communication.

[0066] S203: When the vehicle is in a wake-up state, an activation signal is sent to the sensor, triggering the sensor to adjust its own working state to a wake-up state.

[0067] The sensor performs tire pressure monitoring when it is in the wake-up state.

[0068] It is understood that the sensor is mounted on the wheel and has wireless communication capabilities. Therefore, in this embodiment, the activation signal can be sent to the sensor via wireless communication.

[0069] Based on the process shown in S201-S203, this application embodiment adjusts the working state of the sensor based on the control signal to ensure that when the vehicle is in a dormant state, the sensor also enters a dormant state, thereby avoiding the sensor from working for a long time, achieving effective protection of the sensor, extending the service life of the sensor, and reducing the cost of using TPMS.

[0070] To further understand the sensor protection method shown in the embodiments of this application, the embodiments of this application are based on a specific vehicle usage scenario to explain the specific implementation means of the sensor protection method, as shown below.

[0071] 1. When the vehicle's power mode is off and a user-sent lock command is received, the CEM records the lock command in the cache and starts the hibernation timer. The main reason for starting the hibernation timer is that the vehicle does not immediately enter hibernation mode after power-off; it needs a short buffer period for the vehicle's internal functions to gradually shut down. Therefore, the hibernation timer is used to calculate when the vehicle will enter hibernation mode.

[0072] 2. When the sleep timer exceeds the threshold, CEM responds to the latch command in the cache and generates a shutdown signal.

[0073] 3. The CEM sends a shutdown signal to the sensor via an antenna pre-installed on the vehicle. The sensor has a pre-integrated driver program that controls the sensor's operation in response to control signals. Specifically, it stops tire pressure monitoring in response to the shutdown signal and resumes tire pressure monitoring in response to the activation signal.

[0074] 4. Upon receiving the shutdown signal, the sensor responds by adjusting its operating state to a dormant state, thus ceasing tire pressure monitoring and no longer collecting or sending tire pressure information to the receiver.

[0075] It should be noted that after the sensor stops working on tire pressure monitoring, it can also reduce its own power consumption, ensuring the rational use of power and preventing the vehicle from starting without power to perform tire pressure monitoring.

[0076] 5. When the vehicle's power mode is "on" and an unlock command is received from the user, the CEM generates an unlock signal.

[0077] 6. The CEM sends an activation signal to the sensor via an antenna.

[0078] 7. Upon receiving the activation signal, the sensor responds by adjusting its operating state to become an activated state and performs tire pressure monitoring.

[0079] 8. After entering the wake-up state, the sensor sends the real-time monitored tire pressure information to the receiver, which then forwards the tire pressure information to the CEM. In this embodiment, the sensor and the antenna communicate based on low-frequency signals, the sensor and the receiver communicate based on high-frequency signals, and the receiver and the CEM communicate based on the vehicle network.

[0080] 9. CEM performs logical analysis and processing of tire pressure information to obtain feedback information, which is then displayed. Generally, CEM routes the feedback information to multimedia for display.

[0081] For details on the signal interaction processes involved in the specific use cases described above, please refer to [link / reference]. Figure 4 As shown, other usage scenarios for vehicles, such as remote vehicle start, can be found in the implementation process shown in the embodiments of this application, which will not be elaborated here.

[0082] In summary, the sensor protection method described above, in this embodiment, after detecting that the vehicle is powered off, controls the sensor to enter a sleep state, reasonably arranges the sensor's usage time, avoids the sensor from working for a long time, effectively protects the sensor, extends the sensor's service life, and reduces the cost of using the TPMS.

[0083] Corresponding to the sensor protection method provided in the above embodiments of this application, the embodiments of this application also provide a sensor protection device.

[0087] The state determination unit 100 can be used to: determine the vehicle state as a sleep state if the power mode is power-down; and determine the vehicle state as a wake-up state if the power mode is power-on.

[0091] The signal transmitting unit 300 is used to send control signals to the sensor to trigger the sensor to adjust its own working state; the adjusted working state of the sensor is the same as the vehicle state type.

[0092] In the sensor protection device shown in the embodiments of this application, the signal sending unit 300 can be specifically used to: send a shutdown signal to the sensor when the vehicle is in a sleep state, triggering the sensor to adjust its own working state to a sleep state; the sensor stops tire pressure monitoring in the sleep state; and send an activation signal to the sensor when the vehicle is in a wake-up state, triggering the sensor to adjust its own working state to a wake-up state; the sensor performs tire pressure monitoring in the wake-up state.

[0093] The signal transmitting unit 300 can be used to: convert control signals into low-frequency signals through an antenna pre-installed on the vehicle, and send the low-frequency signals to the sensor to trigger the sensor to adjust its own working state; the sensor responds to the low-frequency signals based on its internal process and adjusts its own working state.

[0094] Optionally, the antenna can be installed within the sensor's signal receiving range.

[0095] Based on the various units shown in the sensor protection device, the embodiments of this application can adjust the working state of the sensor according to the vehicle state so that the adjusted working state is consistent with the vehicle state. This ensures that when the vehicle is in a dormant state, the sensor also enters a dormant state, thereby avoiding the sensor from working for a long time, achieving effective protection of the sensor, extending the sensor's service life, and reducing the cost of using the TPMS.
