Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to the field of vehicle control technology, specifically to a vehicle control system. Background Technology

[0002] Passive Entry Passive Start (PEPS) technology, also known as keyless entry and keyless start technology, means that the car owner does not need to use a key. When the car owner is outside the vehicle preparing to open the door or trunk, the car recognizes that a valid key is outside the vehicle, and the owner can open the door or trunk. After the owner enters the car, they only need to press the start switch, and the car recognizes that a valid key is inside the vehicle, and the car can start.

[0003] Currently, automotive PEPS systems generally use radio frequency technology, employing low-frequency (LF) triggering for key positioning and ultra-high-frequency (UHF) key response. The vehicle side needs to be equipped with both low-frequency and high-frequency transceiver modules, resulting in high hardware costs. Summary of the Invention

[0004] This application provides a vehicle control system to reduce the hardware cost of vehicles. The technical solution of this application is as follows:

[0005] According to the technical solution of this application, a vehicle control system is provided, applied to a vehicle. The vehicle control system includes: a vehicle key, a receiving device in the vehicle, and a vehicle control module. The key includes a first Bluetooth module and a first high-frequency module, and the receiving device includes a second Bluetooth module and a second high-frequency module. The vehicle control module is connected to both the second Bluetooth module and the second high-frequency module. The second Bluetooth module is used to establish a communication connection with the first Bluetooth module. The second high-frequency module is used to establish a communication connection with the first high-frequency module when the Bluetooth signal strength value is less than or equal to a preset threshold. The Bluetooth signal strength value is used to characterize the signal strength between the first Bluetooth module and the second Bluetooth module. The vehicle control module is used to control the vehicle based on user control operations when the Bluetooth signal strength value is greater than the preset threshold; or, when the Bluetooth signal strength value is less than or equal to the preset threshold, to control the vehicle based on control commands received from the second high-frequency module. The control commands are sent from the first high-frequency module to the second high-frequency module.

[0006] According to the aforementioned technical means, the vehicle control system is constructed from a Bluetooth transceiver module and a high-frequency transceiver module. Since the Bluetooth transceiver module is less expensive than the low-frequency transceiver module, the vehicle control system in this embodiment can reduce the vehicle's hardware cost. Furthermore, the vehicle control system employs both Bluetooth and high-frequency communication modes. The vehicle control module controls the vehicle based on user commands when the Bluetooth signal strength exceeds a preset threshold. Thus, when the Bluetooth signal is strong, keyless entry and exit functions are achieved using Bluetooth communication mode; when the Bluetooth signal is weak, high-frequency communication mode ensures the quality of control command transmission and reception. In this way, the vehicle control system achieves the convenience of keyless entry and exit while guaranteeing the quality of control command transmission and reception.

[0007] In one possible implementation, the first Bluetooth module is configured to send connection information to the second Bluetooth module upon detecting a Bluetooth signal sent by the second Bluetooth module. The second Bluetooth module, in response to the connection information, establishes a connection with the first Bluetooth module if the connection information is successfully verified.

[0008] According to the above technical means, the first Bluetooth module performs connection verification before connecting with the second Bluetooth module, and connects with the second Bluetooth module only if the verification is successful, thus avoiding incorrect connection.

[0009] In one possible implementation, the first Bluetooth module is in operating mode, and the key further includes a key control module. The key control module is used to switch the operating mode of the first Bluetooth module from operating mode to sleep mode when it is determined that the key is stationary.

[0010] Based on the aforementioned technical means, when the key is detected to be stationary and it is determined that the key does not need to be used during the current time period, the first Bluetooth module is switched to sleep mode to reduce the power consumption of the first Bluetooth module.

[0011] In one possible implementation, the key further includes a key control module and a remote control button. The key control module is used to generate control commands in response to user button presses on the remote control button, and to send vehicle control commands via a first high-frequency module when the Bluetooth signal strength is less than or equal to a preset threshold.

[0012] Based on the above technical means, when the signals between the first Bluetooth module and the second Bluetooth module are poor, communication via a high-frequency module can ensure the quality of transmission and reception of control commands.

[0013] In one possible implementation, the key control module is also used to send vehicle control commands by the first Bluetooth module when the Bluetooth signal strength is greater than a preset threshold.

[0014] In one possible implementation, the key further includes a motion sensing module connected to the key control module. The motion sensing module generates motion parameters for the key and sends these parameters to the key control module. The motion parameters characterize the key's pose. The key control module further determines the key's motion state based on the motion parameters.

[0015] In one possible implementation, the key also includes a power supply module and a wireless charging coil, the power supply module being connected to the wireless charging coil. The wireless charging coil is used to provide power to the power supply module via wireless charging.

[0016] In one possible implementation, the second Bluetooth module includes a Bluetooth antenna.

[0017] In one possible implementation, the second Bluetooth module is further configured to determine the location information of the key and send the key's location information to the vehicle control module. The vehicle control module is further configured to determine the Bluetooth signal strength value based on the location information.

[0018] In one possible implementation, the vehicle control module is specifically used to control the vehicle based on control commands when the Bluetooth signal strength value is less than or equal to a preset threshold and the control command verification passes.

[0019] In one possible implementation, the vehicle doors are locked, and the vehicle control module is specifically used to unlock the vehicle doors based on the user's door-opening operation when the Bluetooth signal strength value is greater than a preset threshold.

[0020] The vehicle control system provided in this application has the following beneficial effects:

[0021] (1) The vehicle control system is constructed from a Bluetooth transceiver module and a high-frequency transceiver module. Since the Bluetooth transceiver module is less expensive than the low-frequency transceiver module, the vehicle control system in this embodiment can reduce hardware costs. Furthermore, the vehicle control system employs both Bluetooth and high-frequency communication modes. The vehicle control module controls the vehicle based on user control operations when the Bluetooth signal strength exceeds a preset threshold. Thus, when the Bluetooth signal is strong, keyless entry and exit functions are achieved using Bluetooth communication mode; when the Bluetooth signal is weak, the high-frequency communication mode ensures the quality of control command transmission and reception. In this way, the vehicle control system achieves the convenience of keyless entry and exit while ensuring the quality of control command transmission and reception.

[0022] (2) The first Bluetooth module performs connection verification before connecting with the second Bluetooth module, and connects with the second Bluetooth module if the verification is successful, thus avoiding incorrect connection.

[0023] (3) Based on the above technical means, when the key is detected to be in a stationary state and it is determined that the key does not need to be used during the current time period, the first Bluetooth module is switched to sleep mode to reduce the power consumption of the first Bluetooth module.

[0024] (4) Based on the above technical means, when the signals between the first Bluetooth module and the second Bluetooth module are poor, the high-frequency module is used to communicate to ensure the quality of control command transmission and reception.

[0030] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0031] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0032] First, a brief introduction to the application scenarios involved in this application will be given.

[0033] PEPS (Keyless Entry & Start) technology means that the car owner does not need to use a key. When the car owner is outside the car and ready to open the door or trunk, the car recognizes that a valid key is outside the car, and the car owner can open the door or trunk. After the car owner enters the car, he only needs to press the start switch, and the car recognizes that a valid key is inside the car, and the car can start.

[0034] Currently, automotive PEPS systems generally use radio frequency technology, employing low-frequency LF triggering for key positioning and ultra-high frequency UHF key response. The vehicle side needs to be equipped with both low-frequency and high-frequency transceiver modules, resulting in high hardware costs.

[0035] To address the aforementioned problems, this application provides a vehicle control system applied to a vehicle. The vehicle control system includes: a vehicle key, a receiving device in the vehicle, and a vehicle control module. The key includes a first Bluetooth module and a first high-frequency module; the receiving device includes a second Bluetooth module and a second high-frequency module; the vehicle control module is connected to both the second Bluetooth module and the second high-frequency module. The second Bluetooth module is used to establish a communication connection with the first Bluetooth module. The second high-frequency module is used to establish a communication connection with the first high-frequency module when the Bluetooth signal strength value is less than or equal to a preset threshold. The Bluetooth signal strength value is used to characterize the signal strength between the first and second Bluetooth modules. The vehicle control module is used to control the vehicle based on user control operations when the Bluetooth signal strength value is greater than the preset threshold. Alternatively, when the Bluetooth signal strength value is less than or equal to the preset threshold, it controls the vehicle based on control commands received from the second high-frequency module. The control commands are sent from the first high-frequency module to the second high-frequency module.

[0036] Thus, the vehicle control system is constructed from a Bluetooth transceiver module and a high-frequency transceiver module. Since the Bluetooth transceiver module is less expensive than the low-frequency transceiver module, the vehicle control system in this embodiment can reduce hardware costs. Furthermore, the vehicle control system employs both Bluetooth and high-frequency communication modes. The vehicle control module controls the vehicle based on user commands when the Bluetooth signal strength exceeds a preset threshold. Thus, when the Bluetooth signal is strong, keyless entry and exit functions are achieved through Bluetooth communication. When the Bluetooth signal is weak, high-frequency communication ensures the quality of control command transmission and reception. In this way, the vehicle control system achieves both the convenience of keyless entry and exit and ensures the quality of control command transmission and reception.

[0037] Secondly, a brief introduction is given to the implementation environment (implementation architecture) involved in the method provided in this application.

[0038] Figure 1 A schematic diagram of a vehicle control system provided in an embodiment of this application is shown. Figure 1 As shown, the vehicle control system 100 includes a vehicle key 101, a vehicle receiving device 102, and a vehicle control module 103. The receiving device 102 is connected to the vehicle control module 103.

[0039] In some embodiments, such as Figure 1 As shown, the key 101 includes a first Bluetooth module 1011 and a first high-frequency module 1012. The receiving device 102 includes a second Bluetooth module 1021 and a second high-frequency module 1022. The vehicle control module 103 is connected to both the second Bluetooth module 1021 and the second high-frequency module 1022. Bluetooth communication is established between the first Bluetooth module 1011 and the second Bluetooth module 1021, and high-frequency communication is established between the first high-frequency module 1012 and the second high-frequency module 1022.

[0040] In some embodiments, the second Bluetooth module 1021 is used to establish a communication connection with the first Bluetooth module 1011.

[0041] The second high-frequency module 1022 is used to establish a communication connection with the first high-frequency module 1012 when the Bluetooth signal strength value is less than or equal to a preset threshold. The Bluetooth signal strength value is used to characterize the signal strength between the first Bluetooth module 1011 and the second Bluetooth module 1021.

[0042] The vehicle control module 103 is used to control the vehicle based on user control operations when the Bluetooth signal strength value is greater than a preset threshold. Alternatively, when the Bluetooth signal strength value is less than or equal to the preset threshold, it controls the vehicle based on control signals received by the second high-frequency module 1022 from the first high-frequency module 1012.

[0043] In some embodiments, the first Bluetooth module 1011 is configured to scan for Bluetooth signals sent by the second Bluetooth module 1021, and upon detecting a Bluetooth signal sent by the second Bluetooth module 1021, generate first connection information and send the first connection information to the second Bluetooth module 1021. Correspondingly, upon receiving the first connection information sent by the first Bluetooth module 1011, the second Bluetooth module 1021 verifies the connection information, and if the verification is successful, establishes a connection with the first Bluetooth module 1011.

[0044] In other embodiments, the first Bluetooth module 1011 is used to broadcast Bluetooth signals. Correspondingly, upon detecting the Bluetooth signal broadcast by the first Bluetooth module 1011, the second Bluetooth module 1021 generates second connection information and sends the second connection information to the first Bluetooth module 1011. Accordingly, the first Bluetooth module 1011 establishes a connection with the second Bluetooth module 1021 in response to the second connection information sent by the second Bluetooth module 1021.

[0045] In some embodiments, when the first Bluetooth module 1011 is connected to the second Bluetooth module 1021, the first Bluetooth module 1011 sends a first control command to the second Bluetooth module 1021. Correspondingly, the second Bluetooth module 1021 responds to the first control command sent by the first Bluetooth module 1011 and forwards the first control command to the vehicle control module 103. Further, the vehicle control module 103 controls the vehicle based on the first control command.

[0046] In some embodiments, the first high-frequency module 1012 is used to send a second control command to the second high-frequency module 1022. Correspondingly, upon receiving the second control command sent by the first high-frequency module 1012, the second high-frequency module 1022 forwards the second control command to the vehicle control module 103. Further, upon receiving the second control command sent by the second high-frequency module 1022, the vehicle control module 103 controls the vehicle based on the second control command.

[0047] It should be noted that the first control instruction and the second control instruction can be the same instruction or different instructions, and this application embodiment does not limit this.

[0048] Understandably, the key 101 can send control commands through the first high-frequency module 1012 and also through the first Bluetooth module 1011.

[0049] The vehicle control system provided in this application embodiment offers the following advantages: The vehicle control system is constructed from a Bluetooth transceiver module and a high-frequency transceiver module. Since the Bluetooth transceiver module is less expensive than the low-frequency transceiver module, the vehicle control system in this application embodiment can reduce hardware costs. Furthermore, the vehicle control system employs both Bluetooth and high-frequency communication modes. The vehicle control module controls the vehicle based on user control operations when the Bluetooth signal strength exceeds a preset threshold. Thus, when the Bluetooth signal is strong, keyless entry and exit functions are achieved using Bluetooth communication mode; when the Bluetooth signal is weak, the high-frequency communication mode ensures the quality of control command transmission and reception. In this way, the vehicle control system achieves the convenience of keyless entry and exit while ensuring the quality of control command transmission and reception.

[0050] In one design, to avoid connection errors, a first Bluetooth module 1011 is used to send connection information to a second Bluetooth module 1021 upon detecting a Bluetooth signal sent by the second Bluetooth module 1021.

[0051] In some embodiments, such as Figure 2As shown, the key 101 also includes a key control module 1013. The key control module 1013 is connected to both the first Bluetooth module 1011 and the first high-frequency module 1012. The key control module 1013 is used to generate connection information and send the connection information from the first Bluetooth module 1011 to the second Bluetooth module 1021 when the first Bluetooth module 1011 scans for a Bluetooth signal sent by the second Bluetooth module 1021. The connection information includes one or more of the following: a key ID, the identifier of the first Bluetooth module, and a connection request identifier.

[0052] In some embodiments, the first Bluetooth module 1011 is configured to scan for Bluetooth signals and, if a Bluetooth signal is detected, determine whether it is a Bluetooth signal sent by the second Bluetooth module 1021. Further, if it is determined that the detected Bluetooth signal is sent by the second Bluetooth module 1021, it is determined that the Bluetooth signal of the second Bluetooth module 1021 has been detected, and connection information is generated. Subsequently, the first Bluetooth module 1011 sends the connection information.

[0053] In some embodiments, the connection information is encrypted.

[0054] The second Bluetooth module 1021 is used to establish a connection with the first Bluetooth module 1011 in response to connection information and if the connection information is verified.

[0055] In some embodiments, the second Bluetooth module 1021 receives connection information sent from the first Bluetooth module 1011 and forwards the connection information to the vehicle control module 103. Further, upon receiving the connection information forwarded by the second Bluetooth module 1021, the vehicle control module 103 verifies the connection information, and if the verification is successful, controls the second Bluetooth module 1021 to establish a connection with the first Bluetooth module 1011.

[0056] In other embodiments, the second Bluetooth module 1021 receives connection information sent from the first Bluetooth module 1011 and verifies the connection information. Further, if the connection information is successfully verified, the second Bluetooth module 1021 establishes a connection with the first Bluetooth module 1011.

[0057] In one design, to reduce the power consumption of the first Bluetooth module, the first Bluetooth module 1011 is in an operating mode, and the key 101 also includes a key control module 1013.

[0058] For example, the key control module 1013 can be a microcontroller unit (MCU), or other control units. This application does not limit the specific implementation of the embodiment.

[0059] The key control module 1013 is used to switch the working mode of the first Bluetooth module 1011 from the running mode to the sleep mode when it is determined that the key is stationary.

[0060] In some embodiments, such as Figure 2 As shown, the key 101 also includes a motion sensing module 1014. The motion sensing module 1014 is used to collect motion parameters of the key 101 and send the motion parameters to the key control module 1013 in real time or periodically. Accordingly, the key control module 1013 determines the motion state of the key 101 based on the motion parameters sent by the motion sensor 1014.

[0061] Subsequently, the key control module 1013 is used to switch the working mode of the first Bluetooth module 1011 from the running mode to the sleep mode and disconnect the connection with the second Bluetooth module 1021 when it is determined that the key is in a stationary state.

[0062] In some other embodiments, the first Bluetooth module 1011 is in sleep mode. The key control module 1013 is further configured to switch the operating mode of the first Bluetooth module 1011 from sleep mode to running mode when it is determined that the key is in motion.

[0063] Understandably, when the key is stationary, the operating mode of the first Bluetooth module 1011 is switched from running mode to sleep mode to reduce the power consumption of the first Bluetooth module 1011.

[0064] In a design, such as Figure 2 As shown, key 101 includes a key and also includes remote control button 1015.

[0065] In some embodiments, the remote control button 1015 can be one remote control button or multiple remote control buttons. This application embodiment does not specifically limit the number of remote control buttons.

[0066] The key control module 1013 is used to generate vehicle control commands corresponding to button operations in response to button operations. When the Bluetooth signal strength is less than or equal to a preset threshold, the first high-frequency module 1012 sends the vehicle control commands. The button operation is pressing the remote control button 1015. The key control module 1013 is also used to send vehicle control commands via the first Bluetooth module 1011 when the Bluetooth signal strength is greater than a preset threshold.

[0067] For example, taking the operation of pressing the unlock button as an example, the key control module 1013 responds to the operation of pressing the unlock button and determines whether the Bluetooth signal strength value is less than or equal to a preset threshold. Further, if the Bluetooth signal strength value is less than or equal to the preset threshold, an unlock control command is generated and sent through the first high-frequency module 1012.

[0068] It should be noted that the preset threshold is set in advance by the operation and maintenance personnel, and the size of the preset threshold is not specifically limited in this application embodiment.

[0069] Understandably, in the vehicle control system of this application embodiment, when the Bluetooth signal between the first Bluetooth module 1011 and the second Bluetooth module 1021 is weak, control commands are sent through a high-frequency module, thereby ensuring the quality of control command transmission and reception.

[0070] In some embodiments, the key 101 further includes a motion sensing module 1014, which is connected to the key control module 1013.

[0071] The motion sensing module 1014 generates motion parameters for the key and sends these parameters to the key control module 1013. The key control module 1013 also determines the key's motion state based on these motion parameters. The motion parameters characterize the key's pose.

[0072] In one design, for convenient charging of the key, the key 101 also includes a power supply module 1016 and a wireless charging coil 1017. The power supply module 1016 is connected to a first Bluetooth module 1011, a key control module 1013, a motion sensing module 1014, a remote control button 1015, and a first high-frequency module 1012. The power supply module 1016 is used for wireless charging via the wireless charging coil 1017.

[0073] A wireless charging coil is used to provide power to the power supply module via wireless charging.

[0074] In a design, such as Figure 2 As shown, the second Bluetooth module 1021 includes a Bluetooth antenna.

[0075] In some embodiments, the second Bluetooth module 1021 listens for or scans for Bluetooth signals via a Bluetooth antenna.

[0076] In one design, the vehicle control module 103 is specifically used to respond to the control command sent by the second high-frequency module 1022, verify the control command, and control the vehicle based on the control command if the control command is verified.

[0077] In some embodiments, the control command is an encrypted command. The vehicle control module 103, in response to the control command sent by the second high-frequency module 1022, decrypts and verifies the control command, and if the decryption and verification of the control command is successful, controls the vehicle based on the control command.

[0078] In some embodiments, the control command includes a key identifier. The vehicle control module 103, in response to the control command sent by the second high-frequency module 1022, verifies the key identifier and, if the key identifier verification is successful, controls the vehicle based on the control command.

[0079] In some embodiments, the vehicle doors are locked. The vehicle control module 103 is specifically used to unlock the vehicle doors based on the user's door opening operation when the Bluetooth signal strength value is greater than a preset threshold.

[0080] In some embodiments, the second Bluetooth module 1021 is further configured to receive Bluetooth signals transmitted by the first Bluetooth module 1011 via a Bluetooth antenna, and determine the position of the first Bluetooth module 1011 based on the Bluetooth signals transmitted by the first Bluetooth module 1011 and a preset position algorithm. Further, the second Bluetooth module 1021 transmits the position of the first Bluetooth module 1011 to the vehicle control module 103.

[0081] Correspondingly, the vehicle control module 103 responds to the user's control operation on the vehicle, determines whether the position of the first Bluetooth module 1011 is within a preset range, and controls the vehicle based on the user's control operation on the vehicle if the position of the first Bluetooth module 1011 is within the preset range.

[0082] For example, taking a preset range as a circular area with a radius of 3 meters centered on the vehicle's main control board, the vehicle control module 103, in response to the user's operation of opening the trunk, determines whether the current position of the first Bluetooth module 1011 is within the preset range. If the current position of the first Bluetooth module 1011 is within the preset range, the vehicle control module 103, in response to the operation of opening the trunk, unlocks the vehicle's trunk.

[0083] For example, taking the preset range as inside a vehicle, the vehicle control module 103, in response to the operation of starting the vehicle, determines whether the first Bluetooth module 1011 is located inside the vehicle, and starts the vehicle if the first Bluetooth module 1011 is located inside the vehicle.

[0084] In some embodiments, the second Bluetooth module is further configured to determine the location information of the key and send the key's location information to the vehicle control module. The vehicle control module is further configured to determine the Bluetooth signal strength value based on the location information.

[0085] To better understand the vehicle control system provided in the embodiments of this application, such as... Figure 3 As shown, a vehicle control method is illustrated, comprising: S201-S209.

[0086] S201. When the key is detected to be in motion, the working mode of the first Bluetooth module 1011 is woken up from the sleep mode to the working mode.

[0087] In some embodiments, the first Bluetooth module 1011 is in sleep mode. When the key control module 1013 detects that the key is in motion, it wakes the first Bluetooth module 1011 from sleep mode to working mode.

[0088] S202, the first Bluetooth module 1011 broadcasts a Bluetooth signal. Correspondingly, the second Bluetooth module 1021 scans the Bluetooth signal broadcast by the first Bluetooth module 1011.

[0089] S203, the second Bluetooth module 1021 performs connection authentication on the first Bluetooth module 1011.

[0090] S204. If the connection authentication of the first Bluetooth module 1011 is successful, the second Bluetooth module 1021 establishes a connection with the first Bluetooth module 1011.

[0091] S205, the second Bluetooth module 1021 determines the position of the first Bluetooth module 1011.

[0092] S206, the second Bluetooth module 1021 sends the location of the first Bluetooth module 1011 to the vehicle control module 103. Correspondingly, the vehicle control module 103 receives the location of the first Bluetooth module 1011 sent by the second Bluetooth module 1021.

[0093] S207, the vehicle control module 103 receives Bluetooth control commands from the second Bluetooth module 1021.

[0094] In some embodiments, the first Bluetooth module 1011 sends a Bluetooth control command to the second Bluetooth module 1021. Correspondingly, the second Bluetooth module 1021 receives the Bluetooth control command sent from the first Bluetooth module 1011 and forwards the Bluetooth control command to the vehicle control module 103.

[0095] S208. When the position of the first Bluetooth module 1011 is within a preset range, the vehicle control module 103 controls the vehicle based on Bluetooth control commands.

[0096] In another scenario, if the location of the first Bluetooth module 1011 is not within the preset range, the vehicle control module 103 discards the Bluetooth control command.

[0097] S209. When the key is detected to be stationary, the key control module 1013 switches the working mode of the first Bluetooth module 1011 from working mode to sleep mode.

[0098] In some embodiments, when the key is detected to be stationary, the key control module 1013 disconnects the connection between the first Bluetooth module 1011 and the second Bluetooth module 1021, and wakes the first Bluetooth module 1011 from the working mode to the sleep mode.

[0099] To better understand the vehicle control system provided in the embodiments of this application, such as... Figure 4 As shown, a vehicle control method is illustrated, including: S301-S304.

[0100] S301, In response to the control operation of pressing the target button, the key control module 1013 generates a vehicle control command corresponding to the control operation.

[0101] S302, the key control module 1013 sends vehicle control commands through the first high-frequency module 1012. Correspondingly, the second high-frequency module 1022 receives the vehicle control commands sent from the first high-frequency module 1012.

[0102] S303, the second high-frequency module 1022 forwards vehicle control commands to the vehicle control module 103. Correspondingly, the vehicle control module 103 receives the vehicle control commands forwarded by the second high-frequency module 1022.

[0103] S304, Vehicle control module 103 responds to vehicle control commands and controls the vehicle based on the vehicle control commands.

[0104] For example, the vehicle control command is a door unlock command, and the vehicle control module responds to the door unlock command by controlling the door to unlock.

[0105] For example, the vehicle control command is a door locking command, and the vehicle control module responds to the door locking command by controlling the door to lock.

[0106] This application provides a vehicle equipped with a vehicle control system 100.
