Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and more specifically, to a vehicle control method, a vehicle control device, a vehicle, and a computer-readable storage medium within the field of vehicle control technology. Background Technology

[0002] With the rapid development of modern intelligent technology, vehicles can receive control signals transmitted by the vehicle key on the radio frequency band to unlock or lock the vehicle. However, due to the complexity of radio frequency signals in the vehicle's surrounding environment, interference may occur with the control signals used to unlock or lock the vehicle, causing delays or malfunctions in unlocking or locking, thus reducing the user experience. Summary of the Invention

[0003] This application provides a vehicle control method, a vehicle control device, a vehicle, and a computer-readable storage medium. The method can avoid interference from radio frequency signals in the vehicle's surrounding environment to the vehicle's control signals, reduce the possibility of vehicle unlocking or locking failures, and thus improve the user experience.

[0004] In a first aspect, a vehicle control method is provided, the method comprising: if a vehicle key is detected, acquiring a signal of at least one frequency band in the vehicle environment, wherein the at least one frequency band is a radio frequency band in the vehicle environment that is in an operating state; determining a target frequency band based on the at least one frequency band, wherein the target frequency band is different from the at least one frequency band; receiving a vehicle lock control signal transmitted by the vehicle key in the target frequency band, and unlocking or locking the vehicle, wherein the vehicle lock control signal includes an unlock signal or a lock signal of the vehicle.

[0005] In the above technical solution, when detecting the vehicle key, a radio frequency band different from the one active in the vehicle environment is identified as the target frequency band. This target frequency band is then used to receive the vehicle unlocking or locking signals transmitted by the vehicle key within that band, thus unlocking or locking the vehicle. By using a non-active radio frequency band for the transmission of the vehicle lock control signals, it avoids receiving vehicle lock control signals transmitted by the vehicle key using an active frequency band. This prevents interference from radio frequency signals in the vehicle's surrounding environment, reduces the possibility of unlocking or locking malfunctions, and improves the user experience.

[0006] In conjunction with the first aspect, in some implementations of the first aspect, the vehicle includes a transmission module, which includes a Bluetooth module. After locking the vehicle, the method further includes: after a preset duration of locking, receiving the vehicle lock control signal via the Bluetooth module in a broadcast manner.

[0007] In the above technical solution, the vehicle lock control signal is received via broadcast using a Bluetooth module, which can reduce the power consumption of the vehicle when receiving the vehicle lock control signal in sleep mode, thereby achieving the goal of saving vehicle energy consumption.

[0008] In conjunction with the first aspect and the above implementation methods, in some implementation methods of the first aspect, the transmission module further includes a frequency band receiving module, which is used to acquire signals of at least one frequency band; after the preset duration of the locking, the frequency band receiving module is in a sleep state.

[0009] In conjunction with the first aspect and the above implementation methods, in some implementation methods of the first aspect, the method of determining the target frequency band based on the at least one frequency band includes: if the at least one frequency band includes a first frequency band, determining the target frequency band as a second frequency band, wherein the first frequency band is different from the second frequency band; if the at least one frequency band includes both the first frequency band and the second frequency band, determining the target frequency band as the frequency band corresponding to the Bluetooth module.

[0010] In the above technical solution, determining the non-working radio frequency band based on the working frequency band can prevent interference caused by the working frequency band to unlocking or locking the vehicle.

[0011] In combination with the first aspect and the above implementation methods, in some implementation methods of the first aspect, the method of receiving the vehicle lock control signal transmitted by the vehicle key in the target frequency band and unlocking or locking the vehicle includes: receiving the vehicle lock control signal and unlocking the vehicle when the vehicle is in a vehicle armed state.

[0012] In the above technical solution, when the vehicle is in a vehicle armed state, the vehicle can be unlocked using the received vehicle lock control signal, which can ensure that the vehicle can meet the unlocking conditions, thereby avoiding the failure of the unlocking signal.

[0013] In conjunction with the first aspect and the above implementation methods, in some implementation methods of the first aspect, the vehicle includes a transmission module, and after a preset duration of locking, the vehicle lock control signal is received via the Bluetooth module in a broadcast manner. The method includes: after the preset duration of locking, the vehicle lock control signal is received via the Bluetooth module in a periodic broadcast manner.

[0014] In the above technical solution, the vehicle lock control signal is received by the Bluetooth module in a periodic broadcast manner, which can ensure the timeliness of receiving the vehicle lock control signal and thus improve the vehicle unlocking efficiency.

[0015] In conjunction with the first aspect and the above implementation methods, in some implementation methods of the first aspect, the method further includes: if the vehicle key is detected to be inside the vehicle, receiving a pairing instruction, the pairing instruction being used to pair the vehicle with the vehicle key; and sending pairing data to the vehicle key according to the pairing instruction, so that the vehicle and the vehicle key are successfully paired.

[0016] In the above technical solution, once the vehicle and the vehicle key are successfully paired, a signal transmission channel for signal transmission between the vehicle and the vehicle key can be established.

[0017] In summary, this application establishes a signal transmission channel for signal transmission by pairing the vehicle with the vehicle key; and when detecting the vehicle key, it uses a non-operating radio frequency band to receive the vehicle unlock signal or vehicle lock signal transmitted by the vehicle key in the non-operating radio frequency band on the signal transmission channel to unlock or lock the vehicle. This avoids interference from radio frequency signals in the vehicle's surrounding environment on the vehicle's control signals, reduces the possibility of vehicle unlocking or locking failure, and improves the user experience. In addition, after the vehicle is locked, since the frequency band receiving module is in a sleep state, it can receive the vehicle lock control signal through the Bluetooth module using a periodic broadcast method, reducing the power consumption of the vehicle receiving the vehicle lock control signal in the sleep state, thereby saving vehicle energy and ensuring the timeliness of receiving the vehicle lock control signal.

[0018] Secondly, a vehicle control device is provided, comprising: an acquisition module for acquiring signals of at least one frequency band in the vehicle environment if a vehicle key is detected, wherein the at least one frequency band is a radio frequency band in the vehicle environment that is in operation; a determination module for determining a target frequency band based on the at least one frequency band, wherein the target frequency band is different from the at least one frequency band; and a receiving module for receiving a vehicle lock control signal transmitted by the vehicle key in the target frequency band, and unlocking or locking the vehicle, wherein the vehicle lock control signal includes an unlock signal or a lock signal of the vehicle.

[0019] In conjunction with the second aspect, in some implementations of the second aspect, the vehicle includes a transmission module, which includes a Bluetooth module. After the vehicle is locked, the receiving module is further configured to: receive the vehicle lock control signal via the Bluetooth module in a broadcast manner after a preset locking time.

[0020] In conjunction with the second aspect and the above implementation methods, in some implementation methods of the second aspect, the transmission module further includes a frequency band receiving module, which is used to acquire signals of at least one frequency band; after the preset duration of the blocking, the frequency band receiving module is in a sleep state.

[0021] In conjunction with the second aspect and the above implementation methods, in some implementation methods of the second aspect, the determination module is specifically used to: if the at least one frequency band includes a first frequency band, determine the target frequency band as a second frequency band, wherein the first frequency band is different from the second frequency band; if the at least one frequency band includes both the first and second frequency bands, determine the target frequency band as the frequency band corresponding to the Bluetooth module.

[0022] In conjunction with the second aspect and the above implementation methods, in some implementation methods of the second aspect, the receiving module is specifically used to: receive the vehicle lock control signal sent by the vehicle key in the target frequency band and unlock or lock the vehicle when the vehicle is in a vehicle armed state, and unlock the vehicle.

[0023] In conjunction with the second aspect and the above implementation methods, in some implementation methods of the second aspect, the vehicle includes a transmission module, which receives the vehicle lock control signal via a broadcast method through the Bluetooth module after the preset locking time. The receiving module is specifically used to receive the vehicle lock control signal via a periodic broadcast method through the Bluetooth module after the preset locking time.

[0024] In conjunction with the second aspect and the above implementation methods, in some implementation methods of the second aspect, the receiving module is further configured to: if the vehicle key is detected to be inside the vehicle, receive a pairing instruction, the pairing instruction being used to pair the vehicle with the vehicle key; and send pairing data to the vehicle key according to the pairing instruction, so that the vehicle and the vehicle key are successfully paired.

[0025] Thirdly, a vehicle is provided, including a memory and a processor.

[0034] The technical solutions of this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, and can include three relationships. For example, A and / or B can represent: including only A, including both A and B, or including only B. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0035] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0036] Figure 1 This is a schematic diagram of a vehicle unlocking or locking scenario provided in an embodiment of this application.

[0037] For example, such as Figure 1 As shown, scenario 100 includes a vehicle 110 and a vehicle key 120. The user can send an unlock signal or a lock signal to the vehicle 110 by triggering the unlock button or lock button on the vehicle key 120. After receiving the unlock signal or lock signal, the vehicle 110 can control the vehicle to unlock or lock.

[0038] Figure 2This is a schematic diagram of the system structure of the vehicle and vehicle key provided in the embodiments of this application.

[0039] For example, such as Figure 2 As shown, system 200 includes vehicle 110, vehicle key 120, and offline device 230.

[0040] The vehicle 110 includes a high-frequency receiving module 111, a body controller 112, a low-frequency antenna 113, a door lock 114, a gateway 115, and a multimedia screen 116.

[0041] For example, the high-frequency receiving module 111 can be used to acquire signals on the radio frequency (RF) band; wherein, the high-frequency receiving module 111 includes an RF1 module and an RF2 module, and the RF1 module and the RF2 module can be used to transmit signals on a preset radio frequency band; for example, the RF1 module is used to transmit signals on the RF1 radio frequency band, which refers to the radio frequency band with a radio frequency range of 433.05MHz-434.79MHz; for example, the center frequency of the RF1 radio frequency band is 433.92MHz.

[0042] For example, the RF2 module can be used to transmit signals on the RF2 radio frequency band. The radio frequency range of the RF2 radio frequency band is different from that of the RF1 radio frequency band. For example, the frequency of the RF2 radio frequency band is 315MHz.

[0043] It should be understood that the RF1 and RF2 radio frequency bands are radio frequency bands that can be used for radio communication.

[0044] The high-frequency receiving module 111 also includes a Bluetooth Low Energy (BLE) module; the BLE module is used for short-range signal transmission; for example, the BLE module can be used to transmit signals in a 2.4 GHz radio frequency band.

[0045] The offline device 230 can be used to trigger the pairing of vehicle 110 and vehicle key 120.

[0046] The body controller 112 can be used to detect the opening or closing of the door lock 114, and to send commands to the high-frequency receiving module 111 to detect the radio frequency band of the vehicle environment. The body controller 112 can also be used to control the pairing of the vehicle 110 and the vehicle key 120.

[0047] Gateway 115 can be used to transmit information between offline device 230 and body controller 112, and the information transmission method is Controller Area Network (CAN) network.

[0048] The multimedia screen 116 can be used to receive and display the pairing code for pairing the vehicle 110 and the vehicle key 120.

[0049] The low-frequency antenna 113 can be used to receive the pairing signal transmitted by the body controller 112 through the low-frequency (LF) band and transmit the pairing signal to the vehicle key 120.

[0050] The vehicle key 120 can be used to receive pairing signals transmitted by the low-frequency antenna 113 and pair with the vehicle 110. The vehicle key 120 includes RF1 and RF2 modules, which can also be used to transmit signals on preset radio frequency bands of 433.92 MHz and / or 315 MHz. The vehicle key 120 also includes a BLE module, which can be used to transmit signals on a 2.4 GHz radio frequency band.

[0051] In such Figure 1 In the scenario shown, the vehicle key 120 can send an unlock signal to the vehicle 110 via the RF1 radio frequency band. However, due to the rapid development of modern intelligent technology, the radio frequency signals in the vehicle's surrounding environment are more complex. The RF1 radio frequency band may include non-unlocking signals, such as call signals, which may interfere with the control signals that unlock or lock the vehicle on the RF1 radio frequency band. This can cause delays or malfunctions in unlocking or locking the vehicle, thus reducing the user experience.

[0052] It should be understood that the vehicle key 120 can also send a locking signal to the vehicle 110 via the RF1 radio frequency band.

[0053] To address the aforementioned issues, this application provides a vehicle control method that avoids interference from the vehicle's surrounding environment, including radio frequency signals in the same frequency band, on the vehicle's control signals, reducing the likelihood of vehicle unlocking or locking malfunctions and thus improving the user experience.

[0054] Figure 3 This is a flowchart illustrating a vehicle control method provided in an embodiment of this application.

[0055] For example, such as Figure 3 As shown, the method 300 includes the following implementation process:

[0056] S310: If a vehicle key is detected, acquire signals from at least one frequency band in the vehicle environment.

[0057] Wherein, at least one of the aforementioned frequency bands is a radio frequency band in an operational state within the aforementioned vehicle environment. An operational radio frequency band refers to a radio frequency band that is occupied within the vehicle environment. For example, if the current environment of the vehicle includes RF1 and RF2 radio frequency bands, when either RF1 or RF2 is occupied, RF1 or RF2 can be represented as an operational radio frequency band; or, when both RF1 and RF2 are occupied, both RF1 and RF2 can be represented as operational radio frequency bands.

[0058] For example, if the vehicle can detect the vehicle key, it means that the user carrying the vehicle key is within range where they can control the vehicle to unlock or lock (e.g., the distance between the vehicle key and the vehicle is 30 meters). The vehicle can obtain at least one radio frequency band in its environment that is in operation, such as the RF1 radio frequency band or the RF2 radio frequency band, or the RF1 radio frequency band and the RF2 radio frequency band.

[0059] S320, determine the target frequency band based on at least one of the above frequency bands.

[0060] The target frequency band mentioned above is different from at least one of the above frequency bands, that is, the target frequency band is a frequency band that is not in operation. The target frequency band can be referred to as "non-operational radio frequency band".

[0061] For example, based on at least one acquired frequency band, the vehicle can identify other frequency bands different from the acquired frequency band as the target frequency band. For instance, when the RF1 radio frequency band is acquired, the RF2 radio frequency band can be identified as the target frequency band.

[0062] For example, if the above-mentioned at least one frequency band includes a first frequency band, the target frequency band is determined to be a second frequency band, and the first frequency band is different from the second frequency band; if the above-mentioned at least one frequency band includes a first frequency band and a second frequency band, the target frequency band is determined to be the frequency band corresponding to the Bluetooth module, thereby avoiding the determined target frequency band being a frequency band in the working state, and thus preventing the frequency band in the working state from interfering with the unlocking or locking of the vehicle.

[0063] For example, RF1 can be designated as the first frequency band, and RF2 as the second frequency band, with RF1 being different from RF2. When the vehicle acquires information about the operating frequency bands, including RF1, RF2 can be identified as the target frequency band.

[0064] Alternatively, when the radio frequency band of the vehicle's operating status includes the RF2 radio frequency band, the RF1 radio frequency band can be determined as the target frequency band; or, when the radio frequency band of the vehicle's operating status includes both the RF1 and RF2 radio frequency bands, the frequency band corresponding to BLE (e.g., 2.4 GHz) can be used as the target frequency band.

[0065] Alternatively, when the radio frequency bands of the vehicle's operating state do not include RF1 and RF2, either RF1 or RF2 can be determined as the target frequency band. The target frequency band can be determined based on the radio frequency bands in the vehicle environment that are in the operating state. This application embodiment does not limit this.

[0066] Table 1 can also be used to explain S320:

[0067] Table 1

[0068] RF1 RF2 RF2 RF1 RF1 and RF2 BLE corresponding frequency band Non-RF1 and RF2 RF1 or RF2

[0069] S330 receives the vehicle lock control signal sent by the vehicle key in the target frequency band and unlocks or locks the vehicle.

[0070] The aforementioned vehicle lock control signals include either the vehicle unlock signal or the vehicle lock signal. These signals can be signals sent by the user triggering the unlock or lock button on the vehicle key, or they can be signals triggered by the user carrying the vehicle key and touching the door handle.

[0071] For example, after determining the target frequency band, the vehicle can send the determined target frequency band, which is the transmission frequency band for the vehicle lock control signal, to the vehicle key. This allows the vehicle key to use the target frequency band to send an unlock signal to control the vehicle to unlock or a lock signal to control the vehicle to lock. When the vehicle receives the unlock signal or the lock signal, it can unlock the vehicle according to the unlock signal or lock the vehicle according to the lock signal.

[0072] For example, when a user unlocks a vehicle, if the vehicle identifies the RF1 radio frequency band as the target frequency band, the vehicle can send a signal from the RF1 radio frequency band, which is the frequency band for transmitting unlock signals, to the vehicle key. The vehicle key will then use the RF1 radio frequency band to send an unlock signal to the vehicle, allowing the vehicle to unlock using the received unlock signal. Alternatively, when a user locks a vehicle, if the vehicle identifies the RF2 radio frequency band as the target frequency band, the vehicle can send a signal from the RF2 radio frequency band, which is the frequency band for transmitting lock signals, to the vehicle key. The vehicle key will then use the RF2 radio frequency band to send a lock signal to the vehicle, allowing the vehicle to lock using the received lock signal.

[0073] For example, when a user unlocks a vehicle using a vehicle key, the vehicle will detect its own status. When the vehicle detects that it is in an armed state, it can unlock the vehicle based on the unlock signal sent by the vehicle key, so as to ensure that the vehicle can meet the unlocking conditions and thus avoid the unlock signal from failing.

[0074] Among them, the vehicle's armed status can refer to the vehicle's anti-theft status being activated.

[0075] For example, when a user locks the vehicle with the vehicle key, the vehicle will detect its own status. When the vehicle detects that it is in the unlocked state, it can lock the vehicle according to the lock signal sent by the vehicle key to ensure that the vehicle can meet the lock conditions, thereby avoiding the lock signal failure.

[0076] Among them, the vehicle's unlocked state refers to the vehicle's anti-theft system being in a dormant state.

[0077] exist Figure 3 In the provided method 300, when detecting the vehicle key, a target frequency band is determined by differentiating itself from the operating frequency band in the vehicle environment. This target frequency band is then used to receive the vehicle unlocking or locking signal transmitted by the vehicle key within the target frequency band, thereby unlocking or locking the vehicle. By using a non-operating radio frequency band for the transmission of the vehicle lock control signal, it prevents the reception of vehicle lock control signals transmitted by the vehicle key using an operating frequency band. This avoids interference from radio frequency signals in the vehicle's surrounding environment, reduces the possibility of vehicle unlocking or locking malfunctions, and thus improves the user experience.

[0078] Figure 4 This is a schematic flowchart illustrating another vehicle control method provided in this application embodiment. The embodiment shown in the figure is... Figure 3 This is based on the embodiment shown.

[0079] For example, such as Figure 4 As shown, the method 400 includes the following implementation process:

[0080] S410, if the vehicle key is detected to be inside the vehicle, a pairing command is received, which is used to pair the vehicle with the vehicle key.

[0081] For example, before pairing a vehicle and its key, the vehicle and key can first undergo RF-LF learning, such as... Figure 2As shown, the offline device can trigger the body controller to send LF signals to drive the low-frequency antenna in the vehicle, causing the low-frequency antenna to send LF signals to the vehicle key in the 125kHz radio frequency band. After receiving the LF signal, the vehicle key sends signals to the high-frequency receiving module in the vehicle using the RF1 radio frequency band and / or the RF2 radio frequency band, thereby completing RF-LF learning. The fact that the vehicle key and the vehicle can complete RF-LF learning indicates that the vehicle key and the vehicle are a match.

[0082] Furthermore, after the vehicle completes RF-LF learning, it can have LF positioning function. This LF positioning function can detect the position of the vehicle key to determine whether the vehicle key is located inside or outside the vehicle.

[0083] For example, when the vehicle key is detected to be inside the vehicle, the vehicle can receive a pairing command triggered by an offline device to pair the vehicle and the vehicle key.

[0084] S420, according to the above pairing instruction, send pairing data to the vehicle key so that the vehicle and the vehicle key are successfully paired.

[0085] For example, after receiving a pairing command, the vehicle... Figure 2 The high-frequency receiving module reads the pairing code broadcast by the vehicle's BLE radio and transmits it to the downstream device for display via the gateway. This allows the user to obtain the pairing code, which is then input through the multimedia screen. The multimedia screen transmits the pairing code signal to the body controller via the CAN network. The body controller then transmits the pairing code signal to the vehicle key via the LF radio frequency band, enabling successful pairing between the vehicle and the vehicle key. Once successfully paired, a signal transmission channel for signal transmission between the vehicle and the vehicle key is established.

[0086] Once the vehicle and vehicle key are successfully paired, when the user uses the vehicle key to unlock or lock the vehicle again, the vehicle key and vehicle can quickly enter a linked state, establishing a signal transmission channel for signal transmission without needing to repeat the pairing process; and... Figure 2 The high-frequency receiving module, including the BLE module chip and the radio frequency (RF1 module and RF2 module) chip, can communicate through the Serial Peripheral Interface (SPI) bus system to wake up the RF1 module and RF2 module, so that the RF1 module and RF2 module can have the function of receiving signals in the radio frequency band and acquiring frequency band signals in the vehicle environment.

[0087] S310: If a vehicle key is detected, acquire signals from at least one frequency band in the vehicle environment.

[0088] For example, Figure 3 The S320 in the text includes multiple implementations of S321, S322, or S323.

[0089] For example, in S321, if at least one frequency band includes the first frequency band, the target frequency band is determined to be the second frequency band.

[0090] For example, S322, if the above-mentioned at least one frequency band does not include the first frequency band and the second frequency band, the target frequency band is determined to be the first frequency band or the second frequency band.

[0091] For example, in S323, if the above-mentioned at least one frequency band includes the first frequency band and the second frequency band, the target frequency band is determined to be the frequency band corresponding to the Bluetooth module.

[0092] For example, Figure 3 S330 in the text includes multiple implementations such as S331, S332, or S333.

[0093] For example, S331 receives the vehicle lock control signal transmitted by the vehicle key in the target frequency band. The vehicle lock control signal can be a lock signal or an unlock signal.

[0094] For example, in S332, if the vehicle control signal is a locking signal, the vehicle is locked.

[0095] For example, S333, if the vehicle is in a vehicle armed state and the vehicle lock control signal is an unlock signal, the vehicle is unlocked.

[0096] It is understandable that S321, S322, or S323 are multiple implementations of S320, and S331, S332, or S333 are multiple implementations of S330, in Figure 3 The corresponding embodiments have already been described, and will not be repeated here.

[0097] Continue to refer to Figure 4 After the vehicle is locked, S460 is executed, and after the preset locking time, the vehicle lock control signal is received via broadcast through the Bluetooth module.

[0098] The preset duration can be set to 2S, 3S, 5S or 6S, and can be set according to the actual situation. This application embodiment does not limit this.

[0099] The vehicle's transmission module includes a BLE module, combined with... Figure 2 To explain, the transmission module can refer to... Figure 2The high-frequency receiving module in the text refers to the Bluetooth module, which is the BLE module included in the high-frequency receiving module; and the BLE module is a... Figure 2 The BLE module in the vehicle key transmits signals.

[0100] For example, when the vehicle is locked for 3 seconds, it can first enter the vehicle armed state. After entering the vehicle armed state, the vehicle will enter the vehicle sleep state within a short period of time (e.g., 2 seconds). After the vehicle enters the vehicle sleep state, it indicates that the vehicle can enter the low power mode. And, the duration of the vehicle entering the vehicle sleep state from the locked state is used as the preset duration.

[0101] After the vehicle enters sleep mode, it can receive the lock control signal via broadcast through the Bluetooth module in the transmission module. The frequency band receiving module within the transmission module will be in a dormant state, not receiving lock control signals or acquiring signals from at least one frequency band in the vehicle's environment. In other words, the frequency band receiving module's functions of receiving lock control signals and acquiring frequency band signals are disabled. Since the power consumption of a BLE module broadcasting is typically 1-3mA, while the power consumption detected by an RF module is tens of mA, far exceeding the power consumption of a BLE module broadcasting, by putting the frequency band receiving module in a dormant state and only using the BLE module to broadcast the lock control signal when the vehicle enters sleep mode, the power consumption of receiving lock control signals in sleep mode can be reduced, thereby saving vehicle energy.

[0102] Among them, the frequency band receiving module refers to Figure 2 The high-frequency receiver module includes RF1 and RF2 modules; and the RF1 and RF2 modules can be used with... Figure 2 The RF1 and RF2 modules in the vehicle key transmit signals.

[0103] It should be understood that after a vehicle is locked, it can directly enter the vehicle sleep mode. The time required to enter the vehicle sleep mode without going through the vehicle's armed state is much longer than the time required to enter the vehicle sleep mode through the vehicle's armed state, for example, 10 minutes or 15 minutes.

[0104] For example, after the preset duration of the locking, the vehicle lock control signal is received periodically via the Bluetooth module.

[0105] The periodic broadcast refers to broadcasting the vehicle lock control signal at fixed intervals, which can also be referred to as "polling broadcast". The fixed interval can be set to 10S, 20S or 30S, and this application embodiment does not limit it.

[0106] For example, when the vehicle is locked for 5 seconds, the BLE module in the vehicle receives the lock control signal via broadcast every 10 seconds. By continuously receiving the lock control signal and broadcasting it continuously, the system ensures that the lock control signal sent by the vehicle key is received in a timely manner, thereby improving the unlocking efficiency of the vehicle.

[0107] For example, after the vehicle enters sleep mode, the user carries the vehicle key and touches the door handle to unlock the vehicle. The vehicle can send an unlock request to the vehicle key. After receiving the unlock request, the vehicle key can send an unlock signal to the vehicle through the radio frequency band corresponding to the BLE module to unlock the vehicle. Alternatively, the user can trigger the unlock button on the vehicle key within the range where they can control the vehicle to unlock or lock. The vehicle key can then send an unlock signal to the BLE module in the vehicle through the radio frequency band corresponding to its own BLE module to unlock the vehicle.

[0108] exist Figure 4 In the provided method 400, a signal transmission channel for signal transmission is established by pairing the vehicle with the vehicle key; and when detecting the vehicle key, the unlock signal or lock signal of the vehicle transmitted by the vehicle key in the non-working state radio frequency band is received on the signal transmission channel using the non-working state radio frequency band, so as to unlock or lock the vehicle. This can avoid the interference of radio frequency signals in the vehicle's surrounding environment on the vehicle's control signal, reduce the possibility of vehicle unlocking or locking failure, and thus improve the user experience; in addition, after the vehicle is locked, since the frequency band receiving module is in a sleep state, the vehicle lock control signal can be received through the Bluetooth module in a periodic broadcast manner, reducing the power consumption of the vehicle receiving the vehicle lock control signal in the sleep state, thereby saving vehicle energy consumption and ensuring the timeliness of receiving the vehicle lock control signal.
