Description

Technical Field

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

[0002] Currently, the operation mechanism of mobile phone Bluetooth keys in vehicles relies on the Bluetooth module installed in the vehicle to measure distance and locate, in order to determine the relative position of the mobile phone and the vehicle, and thus decide whether to grant the user the permission to unlock or start the vehicle.

[0003] In related technologies, positioning methods based on received signal strength indication have been widely adopted in frameless vehicle door designs to improve the accuracy of positioning near the doors. However, for vehicles with framed doors, the installation location of Bluetooth modules is limited. They typically cannot be directly deployed behind the B-pillar trim panel because the window frame obstructs the Bluetooth signal, reducing signal strength and affecting positioning accuracy. Furthermore, the space on the window frame is insufficient to accommodate the Bluetooth module, and side-impact safety requirements often limit its installation on the front / rear bumper panels, significantly reducing the accuracy of Bluetooth positioning near the doors. Therefore, a technical problem remains that cannot effectively control the vehicle.

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.

[0034] According to an embodiment of this application, an embodiment of a vehicle control system is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0035] This embodiment provides a vehicle control system, the vehicle including framed doors. Figure 1 This is a schematic diagram of a vehicle control system according to an embodiment of this application, such as... Figure 1 As shown, the vehicle's control system 1000 includes a controller 1002, a Bluetooth module 1004, and a mobile terminal 1006.

[0036] Controller 1002 can be a vehicle body domain controller module.

[0037] Bluetooth module 1004 is installed inside the door handle of the framed door and is connected to controller 1002.

[0038] In this embodiment, the Bluetooth module includes a first Bluetooth module and a second Bluetooth module. The first Bluetooth module can be used to determine the location of the mobile terminal 1006 based on the detected Bluetooth signal of the mobile terminal 1006 when the target switch of the vehicle is turned on; based on the location, it sends a target request to the controller, wherein the controller is used to perform control operations on the vehicle in response to the target request; the second Bluetooth module can be used to send a capacitive sensing signal corresponding to the capacitive sensing area to the controller in response to the capacitive sensing area on the door handle receiving a touch signal when the target switch is turned off, wherein the controller is used to perform control operations on the vehicle in response to the capacitive sensing signal.

[0039] Optionally, the Bluetooth module can be a Bluetooth module with integrated dual-zone capacitors. The target request may include an unlock request or a lock request, and the control operation may include unlocking or locking.

[0040] Optionally, the first Bluetooth module, as the core component of the Bluetooth module, is activated when the target switch of the vehicle (e.g., when the vehicle is near the unlock switch or far from the door lock switch) is in the on state. The Bluetooth chip and optimized Bluetooth antenna in the first Bluetooth module continuously monitor the Bluetooth signal strength from the mobile terminal. Based on the received Bluetooth signal strength and quality, the first Bluetooth module can accurately locate the position of the mobile terminal and determine whether the user is approaching or moving away from the vehicle. When it is determined that the mobile terminal is within the vehicle's unlock or lock area, the first Bluetooth module can automatically send the corresponding unlock or lock request to the controller. Upon receiving the target request, the controller can execute the corresponding unlock or lock command, thereby achieving automatic unlocking or locking of the vehicle.

[0041] Optionally, the second Bluetooth module is activated when the target switch is off. The second Bluetooth module may include a touch chip, electrode pads, and a flexible circuit board, which together form the capacitive sensing area on the door handle (e.g., an inner area and an outer area). When a user touches the inner area (e.g., the inside of the door handle), the second Bluetooth module detects this action and generates a corresponding capacitive sensing signal, which is then sent to the controller to trigger vehicle unlocking. Similarly, when a user touches the outer area (e.g., the outside of the door handle), the second Bluetooth module can also generate a capacitive sensing signal to instruct the vehicle to perform a locking operation. In this way, even if the target switch is off, the user can still manually trigger the vehicle's locking and unlocking functions without worrying about Bluetooth signal obstruction.

[0042] For example, when a target switch (e.g., near the unlock switch or far from the lock switch) is open, the first Bluetooth module analyzes the Bluetooth signal emitted by the mobile terminal to accurately calculate the mobile terminal's position relative to the vehicle. Based on the calculated position information, the first Bluetooth module generates and sends a target request to the controller. These target requests may include instructions to unlock or lock the vehicle, which the controller responds to and executes according to the actual situation. When the target switch is turned off by the user, meaning the system no longer relies on Bluetooth signals for automatic unlocking and locking, the second Bluetooth module is activated. The second Bluetooth module monitors the capacitive sensing areas on both the inside and outside of the door handle, awaiting manual touch from the user. Once user touch on the capacitive sensing area is detected, the second Bluetooth module immediately triggers a capacitive sensing signal and can send the signal to the controller via a data cable. The controller executes the corresponding vehicle control operation, such as unlocking or locking, based on the received capacitive sensing signal.

[0043] Optionally, to ensure stable operation and waterproofing of the vehicle's control system, the Bluetooth module with integrated dual-zone capacitors can utilize a robust and durable housing, internally filled with polyurethane potting compound, and reinforced with precision foam for cushioning and fixation. Wiring harnesses and waterproof connectors connect the circuit board to other electronic systems in the vehicle, ensuring secure and reliable data transmission. Furthermore, a low-dropout linear regulator on the circuit board provides a stable power supply, while a Controller Area Network (CAN) transceiver handles communication with the vehicle's network, ensuring harmonious coexistence between the Bluetooth module and other vehicle components, enabling complete intelligent vehicle control.

[0044] Mobile terminal 1006 can be a mobile phone or a physical remote key. The physical remote key can be simply referred to as a physical key or key. This is just an example, and no specific restrictions are placed on the mobile terminal here.

[0045] In this embodiment, the Bluetooth module with integrated dual-zone capacitors provides a comprehensive intelligent locking and unlocking solution for vehicles with framed doors through its unique design and functional combination. This not only overcomes the limitations of traditional Bluetooth modules but also enhances the user experience, increases the flexibility and security of the vehicle's control system, thereby solving the technical problem of ineffective vehicle control and achieving the technical effect of effective vehicle control.

[0046] In the control system of the vehicle described in this application, a Bluetooth module is deployed inside the door handle of the framed door and connected to the controller. When the target switch of the vehicle is open, the first Bluetooth module determines the location of the mobile terminal based on the detected Bluetooth signal of the mobile terminal. Based on the location, a target request is sent to the controller, which responds to the target request and performs control operations on the vehicle. When the target switch is closed, the second Bluetooth module, in response to a touch signal received in the capacitive sensing area on the door handle, sends a corresponding capacitive sensing signal to the controller, which responds to the capacitive sensing signal and performs control operations on the vehicle. In other words, by integrating a dual-zone capacitive Bluetooth module into the door handle, this application significantly improves the Bluetooth signal reception and processing capabilities near the door without sacrificing the original keyless entry function, thereby improving positioning accuracy and solving the technical problem of ineffective vehicle control, achieving effective vehicle control.

[0047] The above-mentioned system of this application will be further described below.

[0048] As an optional implementation, the first Bluetooth module includes: a Bluetooth antenna, used to determine the distance between the mobile terminal and the vehicle based on the detected Bluetooth signal when the target switch is turned on; and to locate the mobile terminal based on the distance to obtain its location; and a Bluetooth chip, used to send a target request corresponding to the geographical area to the controller based on the geographical area where the location is located.

[0049] In this embodiment, the Bluetooth antenna can be used to determine the distance between the mobile terminal and the vehicle based on the detected Bluetooth signal when the target switch is on. For example, the Bluetooth antenna can locate the user's mobile phone position in real time. The distance between the mobile terminal and the vehicle is determined based on the detected Bluetooth signal, such as detecting the distance from the mobile phone to the vehicle.

[0050] Optionally, the design and deployment of the Bluetooth antenna are crucial to ensuring signal reception quality. With the target switch on, the Bluetooth antenna can continuously monitor Bluetooth signals in the environment. The Bluetooth antenna can capture and measure signals emitted by the mobile terminal. The signal strength, frequency, and angle of arrival can be used to calculate the relative distance between the mobile terminal and the vehicle. This process is dynamic; as the user moves, the Bluetooth antenna can update the distance information in real time, thereby achieving continuous positioning of the mobile terminal.

[0051] For example, by observing the changing trend of the Received Signal Strength Indicator (RSSI), or using more advanced ranging technologies such as Bluetooth 5.1's Angle of Arrival (AoA) or Angle of Departure (AoD) measurements, the Bluetooth antenna can determine the distance between the phone and the vehicle. If the user's phone enters a predefined unlocked area, the Bluetooth antenna detects the shortened distance and sends this information to the Bluetooth chip for further processing.

[0052] Optionally, in response to the Bluetooth antenna detecting that the mobile terminal has entered a specific geographical area, the Bluetooth chip can determine whether the phone is within the unlock or lock range based on the received location information. If it is confirmed that the phone is in the correct location, the Bluetooth chip will generate a corresponding unlock or lock request and send the unlock or lock request to the controller (e.g., the vehicle domain controller module) via the data bus.

[0053] Optionally, a geographic region refers to a virtual area that can be used to represent a vehicle's safety and convenience requirements, such as an external unlocking zone (external area) and an internal locking zone (internal area). For example, when the distance measured by the Bluetooth antenna is below a distance threshold, it indicates that the phone has entered the unlocking zone. The Bluetooth chip will generate an unlock request, package it together with the location information, and send it to the vehicle domain controller module via the CAN bus. Conversely, if the phone is far from the vehicle and the distance continuously detected by the Bluetooth antenna exceeds another distance threshold, the Bluetooth chip will generate a locking request, which will also be sent to the controller via the CAN bus to achieve automatic locking.

[0054] In this embodiment, by fully utilizing the functions of the Bluetooth antenna and chip, combined with a geographic location strategy, the location of the mobile terminal can be determined intelligently and accurately, and the vehicle's locking and unlocking operations can be performed accordingly, greatly improving the user experience and the security of the vehicle's control system.

[0055] As an optional implementation, the control operation includes an unlocking operation or a locking operation, the target request includes an unlocking request corresponding to the unlocking operation, or a locking request corresponding to the locking operation, the geographic area includes a first geographic area or a second geographic area, the second geographic area being located outside the first geographic area, and the Bluetooth chip is used to send a target request corresponding to the location to the controller based on the location area through the following steps: in response to the location being in the first geographic area outside the vehicle, an unlocking request corresponding to the first geographic area is sent to the controller, wherein the controller is used to control the vehicle to perform an unlocking operation in response to the unlocking request; in response to the location being in the second geographic area outside the vehicle, a locking request corresponding to the second geographic area is sent to the controller, wherein the controller is used to control the vehicle to perform a locking operation in response to the locking request.

[0056] In this embodiment, the Bluetooth module integrating dual-zone capacitors further refines the control logic and geographical area division to achieve more precise and scenario-based vehicle locking and unlocking functions. The first geographical area can be used to represent the unlocking area near the vehicle; when a mobile terminal enters the first geographical area, it can be recognized as the user intending to unlock the vehicle. The second geographical area can be located outside the first geographical area, away from the vehicle's locking area; when a mobile terminal enters or remains in the second geographical area, it can be recognized as the user intending to lock the vehicle.

[0057] Optionally, when the mobile terminal is in the first geographic area (unlocked area), the Bluetooth chip can detect that the mobile terminal has entered an area close to the vehicle and automatically send an unlock request to the controller. After receiving the unlock request, the controller performs the vehicle unlocking operation to allow the user to enter the vehicle.

[0058] Optionally, when the mobile terminal is in the second geographical area (locked area), the Bluetooth chip can detect that the mobile terminal is away from the vehicle and generate a lock request to send to the controller. The controller responds to the lock request and performs the vehicle lock operation to ensure the vehicle's safety status after the user leaves.

[0059] Optionally, through the above methods, the Bluetooth chip can intelligently adjust its response strategy according to different geographical areas, thereby achieving a seamless and secure vehicle locking and unlocking experience. This not only improves the user experience but also enhances vehicle security, ensuring that the correct control operations are performed at the right time and place.

[0060] Optionally, the Bluetooth module can dynamically identify the process of a mobile terminal moving from one geographic area to another. For example, when a user approaches a vehicle with their phone, the Bluetooth module can detect the phone moving from a second geographic area (away from the vehicle) to a first geographic area (closer to the vehicle) and switch from locked monitoring mode to unlocked monitoring mode accordingly. Conversely, when the phone moves away from the vehicle, the Bluetooth module can recognize this change and automatically switch back to locked monitoring mode.

[0061] In this embodiment of the invention, the aforementioned dynamic identification and control logic of geographical areas enables the Bluetooth module with integrated dual-zone capacitors to adapt to different user behaviors and vehicle usage scenarios, providing more intelligent and safer vehicle control functions.

[0062] As an optional implementation, the target switch includes a first type of switch corresponding to the unlocking operation and a second type of switch corresponding to the locking operation. The Bluetooth antenna is used to determine the distance between the mobile terminal and the vehicle based on the detected Bluetooth signal when the target switch is open by the following steps: when the first type of switch is open, in response to the direction in which the mobile terminal approaches the framed door, the distance between the approaching mobile terminal and the vehicle is determined based on the detected Bluetooth signal; when the second type of switch is open, in response to the direction in which the mobile terminal moves away from the framed door, the distance between the moving mobile terminal and the vehicle is determined based on the detected Bluetooth signal.

[0063] In this embodiment, the target switch includes a first type of switch corresponding to the unlocking operation (e.g., when the vehicle approaches the unlocking switch) and a second type of switch corresponding to the locking operation (e.g., when the vehicle moves away from the locking switch).

[0064] Optionally, when the first type of switch (vehicle approaching the unlock switch) is activated, the Bluetooth antenna begins monitoring the Bluetooth signal in the space near the vehicle door. Once a mobile terminal (such as a user's mobile phone) is detected moving towards the vehicle, the Bluetooth antenna calculates the actual distance between the mobile terminal and the vehicle based on the strength of the received Bluetooth signal and other parameters, such as the signal frequency and angle. This process is performed in real time until the mobile terminal enters a pre-defined first geographical area (unlock zone). At this point, the Bluetooth antenna transmits the distance information to the Bluetooth chip, which determines whether the unlocking conditions are met. If they are met, an unlocking request is generated and sent to the controller via the CAN bus for unlocking. Conversely, if the mobile terminal does not enter the unlocking zone or the distance does not meet the conditions, no unlocking request will be sent, thus avoiding accidental operation.

[0065] Optionally, when the second type of switch (vehicle-away-from-the-door lock switch) is activated, the Bluetooth antenna is also operational, monitoring the Bluetooth signal away from the vehicle door. As the mobile device begins to move away from the vehicle, the Bluetooth antenna continuously tracks and measures changes in signal strength to calculate and monitor the distance between the mobile device and the vehicle. Once the mobile device enters the second geographic area (locking zone), the Bluetooth antenna immediately notifies the Bluetooth chip, which generates a locking request and transmits it to the controller, triggering the vehicle's locking operation. This ensures automatic locking after the user has moved a certain distance from the vehicle, providing both convenience and safety.

[0066] In this embodiment of the invention, the Bluetooth antenna can not only accurately detect the dynamic position of the mobile terminal when the target switch is open, but also intelligently react according to the preset geographical area boundary, thereby driving the unlocking or locking request of the first Bluetooth module. By closely linking the control logic with the state of the target switch, the Bluetooth module with integrated dual-zone capacitors achieves highly automated vehicle unlocking and locking management, significantly improving user experience and vehicle safety.

[0067] As an optional implementation, the second Bluetooth module includes: an electrode plate, used to sense that the touch signal is received in the capacitive sensing area when the target switch is off, triggering a capacitive sensing signal; and a touch chip, used to connect to the electrode plate via a flexible circuit board, used to detect the triggered capacitive sensing signal, and to send the detected capacitive sensing signal to the controller.

[0068] In this embodiment, the second Bluetooth module, as another key component of the Bluetooth module integrating dual-zone capacitors, can provide users with keyless entry and exit confirmation functions through the collaborative work of the electrode plate and the touch chip when the target switch (such as the vehicle approaching the unlock switch or the vehicle moving away from the door lock switch) is closed.

[0069] Optionally, electrode pads can be arranged on the inner and outer sides of the door handle, i.e., the capacitive sensing area, to detect the user's touch actions. When the user touches the door handle, that is, the capacitive sensing area receives the touch signal, it can generate a capacitive sensing signal, which is an initial indication that the user intends to unlock or lock the vehicle.

[0070] Optionally, the touch chip can be tightly connected to the electrode pad via a flexible circuit board, and can be used to detect and process the capacitive sensing signal generated by the electrode pad. When a user's finger touches a preset capacitive sensing area on the door handle, the electrode pad can sense the capacitance change caused by the touch. This capacitance change is caused by the difference in dielectric constant between the user's finger or mobile terminal and the electrode pad, thus generating a small electric field change around the electrode pad. When the target switch is turned off and the system switches to manual control mode, the electrode pad begins to actively monitor this change. Once a valid touch event (e.g., user touch) is detected, a capacitive sensing signal is triggered. By identifying the change in the capacitive sensing signal, it is determined whether the touch action is valid and in which sensing area (inner or outer area) the touch occurred. Based on the identification result, the touch chip sends the processed capacitive sensing signal to the controller to trigger the corresponding control action.

[0071] For example, when the target switch is off, and a user touches the sensing area on the inside of the door handle with their mobile phone or physical key, the electrode plate detects a change in capacitance and generates a capacitive sensing signal. Upon receiving this signal, the touch chip confirms the user's intention to unlock the vehicle and sends an unlock signal to the body domain controller module. The body domain controller module responds to this unlock request, executes the unlocking operation, and allows the user to enter the vehicle. Conversely, when a user touches the sensing area on the outside of the door handle, the electrode plate also generates a capacitive sensing signal. After detecting and processing the signal, the touch chip generates a locking signal and sends it to the body domain controller module, triggering the vehicle's locking mechanism to ensure vehicle security when unattended.

[0072] In this embodiment of the invention, the above method ensures that even when the target switch is off, and the vehicle is in an environment with heavy signal interference, the user can still safely control the unlocking and locking of the vehicle through simple touch operation, demonstrating the flexibility and reliability of the Bluetooth module with integrated dual-zone capacitors in various usage scenarios.

[0073] As an optional implementation, the control operation includes an unlocking operation or a locking operation. The capacitive sensing signal includes a first capacitive sensing signal corresponding to the unlocking operation or a second capacitive sensing signal corresponding to the locking operation. The capacitive sensing area includes a first capacitive sensing area or a second capacitive sensing area. The first capacitive sensing area is located in the area inside the door handle, and the second capacitive sensing area is located in the area outside the door handle. The touch chip is used to detect the capacitive sensing signal through the following steps, and to send the detected capacitive sensing signal to the controller: in response to detecting the first capacitive sensing signal on the first capacitive sensing area, the detected first capacitive sensing signal is sent to the controller, wherein the controller is used to control the vehicle to perform an unlocking operation in response to the first capacitive sensing signal; in response to detecting the second capacitive sensing signal on the second capacitive sensing area, the detected second capacitive sensing signal is sent to the controller, wherein the controller is used to control the vehicle to perform a locking operation in response to the second capacitive sensing signal.

[0074] In this embodiment, the Bluetooth module integrating dual-zone capacitance employs a combination of capacitive sensing area and touch chip to achieve touch-based unlocking and locking control operations. The capacitive sensing area is clearly divided into a first capacitive sensing area (inner area) and a second capacitive sensing area (outer area), located on the inside and outside of the door handle, respectively. The touch chip can generate and send corresponding capacitive sensing signals to the controller based on different touch actions to perform unlocking or locking operations.

[0075] Optionally, in response to detecting a first capacitive sensing signal in a first capacitive sensing area (e.g., an inner area), the detected first capacitive sensing signal can be sent to a controller, wherein the controller is used to control the vehicle to perform an unlocking operation in response to the first capacitive sensing signal. For example, by touching the inner area of ​​the Bluetooth module, the Bluetooth module will process the capacitive sensing signal and send it to the vehicle domain controller module, and the vehicle can perform unlocking.

[0076] Optionally, in response to detecting a second capacitive sensing signal on a second capacitive sensing area (e.g., the outer area), the detected second capacitive sensing signal is sent to the controller, wherein the controller is used to control the vehicle to perform a locking operation in response to the second capacitive sensing signal. For example, by touching the outer area of ​​the Bluetooth module, the Bluetooth module will process the capacitive sensing signal and send it to the vehicle domain controller module, and the vehicle can perform unlocking.

[0077] For example, when a user touches the first capacitive sensing area on the inside of the door handle, the electrode plate captures this contact event and generates a first capacitive sensing signal. After detecting the first capacitive sensing signal, the touch chip confirms the user's intention to unlock the vehicle and sends the processed first capacitive sensing signal to the body domain controller module via the CAN bus. Upon receiving the signal, the body domain controller module executes the vehicle unlocking operation according to preset logic, allowing the user to enter the vehicle.

[0078] For another example, when a user touches the second capacitive sensing area on the outside of the door handle, the electrode plate generates a second capacitive sensing signal. The touch chip can recognize this signal and, after processing, forward it to the vehicle domain controller module, triggering the vehicle's locking operation. Thus, even when the target switch (such as the vehicle approaching the unlock switch or moving away from the door lock switch) is off, the user can still lock the vehicle using a simple and direct touch method, ensuring vehicle safety.

[0079] In this embodiment of the invention, the touch recognition control method described above not only provides users with flexible control options that do not depend on the on / off state of the target switch, but also enhances the convenience and safety of the vehicle. Especially in complex environments or special circumstances, users can still control the vehicle through intuitive gestures, reflecting the user-friendly design of the Bluetooth module with integrated dual-zone capacitors.

[0080] As an optional implementation, the target switch includes a first type of switch corresponding to the unlocking operation and a second type of switch corresponding to the locking operation. The electrode is used to sense a touch signal received in the capacitive sensing area and trigger the capacitive sensing signal when the target switch is closed by the following steps: when the first type of switch is closed, sense a touch signal received in the first capacitive sensing area and trigger the first capacitive sensing signal; when the second type of switch is closed, sense a touch signal received in the second capacitive sensing area and trigger the second capacitive sensing signal.

[0081] In this embodiment, the target switch is further subdivided into a first type of switch corresponding to the unlocking operation and a second type of switch corresponding to the locking operation. When the target switch is closed, the Bluetooth module with integrated dual-zone capacitance detects direct contact with the vehicle door handle through electrode plates, thereby triggering the corresponding capacitance sensing signal and control operation.

[0082] Optionally, if the first type of switch (e.g., the vehicle approach unlock switch) is off, this means the user needs to manually trigger the unlocking operation instead of relying on automatic Bluetooth positioning. In this case, the electrode pads in the integrated module begin monitoring the user's touch action in the first capacitive sensing area (inner area) on the inside of the door handle. When the user approaches the vehicle and touches the preset inner capacitive sensing area on the door handle with their finger, the electrode pads immediately sense this touch action, resulting in a change in capacitance. This change in capacitance is quickly captured by the touch chip, triggering the first capacitive sensing signal. The touch chip then processes the first capacitive sensing signal, confirms the validity of the touch, and transmits the first capacitive sensing signal to the controller via a flexible circuit board, triggering the vehicle unlocking operation and allowing the user to enter the vehicle.

[0083] Optionally, when the second type of switch (e.g., when the vehicle is away from the door lock switch) is off, the system enters a manual trigger locking state. In this mode, active monitoring of external Bluetooth signals ceases, and the system prepares to receive direct touch signals from the user. When the user leaves the vehicle and touches a preset outer capacitive sensing area on the door handle, the electrode pads respond immediately, detecting the capacitance change caused by the touch. Upon receiving the capacitance change, the touch chip generates a second capacitive sensing signal containing the user's request to lock the vehicle. The touch chip handles the complete processing of the second capacitive sensing signal, including verification, reinforcement, and encoding, and then forwards the signal to the controller via a flexible circuit board to trigger the vehicle's locking mechanism, ensuring vehicle safety.

[0084] In this embodiment of the invention, by fully considering the user's needs in different scenarios, the controller can correctly receive and interpret both the first capacitive sensing signal when the first type of switch is closed and the second capacitive sensing signal when the second type of switch is closed. The controller converts the capacitive sensing signal into specific vehicle control commands, such as "unlock" or "lock". Based on the type of received capacitive sensing signal, the controller will execute the corresponding control operation. If it is the first capacitive sensing signal (corresponding to the unlock operation), the controller will send an unlock command to the vehicle's door lock system; if it is the second capacitive sensing signal (corresponding to the lock operation), it will send a lock command. During the execution of the operation, the controller can also consider the vehicle's current safety status and operating conditions to ensure the safety and suitability of the control commands.

[0085] As an optional implementation, the system includes a circuit board, on which the wiring harness of the Bluetooth module is fixed. The circuit board includes: a transceiver for converting data from the first Bluetooth module into electrical signals and transmitting the electrical signals through the data bus in the system, or receiving data from the data bus and transmitting the received data to the first Bluetooth module; and a voltage regulator for outputting DC voltage to the first Bluetooth module, the second Bluetooth module, and the transceiver.

[0086] In this embodiment, one end of the wiring harness can be soldered to an internal circuit board. The transceiver can be a CAN transceiver. The voltage regulator can be a low-dropout linear regulator.

[0087] Optionally, the transceiver can be used to convert data from the first Bluetooth module into electrical signals and transmit the electrical signals through the data bus of the vehicle's control system, or to receive data from the data bus and send the received data to the first Bluetooth module. For example, it can convert data provided by the Bluetooth chip into electrical signals and then send them out through the data bus, while also receiving bus data and transmitting the data to the Bluetooth chip.

[0088] For example, when a user approaches a vehicle with a mobile device (such as a mobile phone), the first Bluetooth module detects this event and generates a corresponding data packet. The transceiver converts these data packets into electrical signals for transmission to the body domain controller module via a data bus (such as the CAN bus of an in-vehicle network). Conversely, when the body domain controller module sends a command to the first Bluetooth module via the data bus, the transceiver again takes over, converting the received electrical signals back into data packets and transmitting them to the first Bluetooth module to perform the corresponding action (such as unlocking or locking the vehicle).

[0089] Optionally, the voltage regulator can be used to output DC voltage to the first Bluetooth module, the second Bluetooth module, and the transceiver, that is, to provide a stable, low-noise DC voltage output. In the complex electrical environment of a vehicle, the voltage regulator ensures that critical components of the vehicle's control system receive the necessary stable power supply, even under conditions of voltage fluctuations or electromagnetic interference. This stability is crucial for maintaining the positioning accuracy of the Bluetooth module and the normal operation of other components on the circuit board.

[0090] In this embodiment of the invention, by combining the signal conversion capability of the transceiver and the power management capability of the voltage regulator, the circuit board can effectively support various operations of the Bluetooth module with integrated dual-zone capacitors. Whether using Bluetooth signals in automatic unlocking / locking mode or capacitor sensing signals in manual unlocking / locking mode, the stability and reliability of the vehicle control system can be ensured, thereby providing users with a first-class vehicle access experience.

[0091] In the control system of the vehicle described in this application, a Bluetooth module is deployed inside the door handle of the framed door and connected to the controller. When the target switch of the vehicle is open, the first Bluetooth module determines the location of the mobile terminal based on the detected Bluetooth signal of the mobile terminal. Based on the location, a target request is sent to the controller, which responds to the target request and performs control operations on the vehicle. When the target switch is closed, the second Bluetooth module, in response to a touch signal received in the capacitive sensing area on the door handle, sends a corresponding capacitive sensing signal to the controller, which responds to the capacitive sensing signal and performs control operations on the vehicle. In other words, by integrating a dual-zone capacitive Bluetooth module into the door handle, this application significantly improves the Bluetooth signal reception and processing capabilities near the door without sacrificing the original keyless entry function, thereby improving positioning accuracy and solving the technical problem of ineffective vehicle control, achieving effective vehicle control.

[0092] The above technical solutions of the embodiments of this application will be further illustrated below with reference to preferred embodiments of the present invention.

[0093] Currently, for vehicles with frameless doors, Bluetooth modules can be installed behind the B-pillar trim to improve positioning accuracy near the door. However, for vehicles with framed doors, the window frame covers the B-pillar. If the module were forcibly installed behind the B-pillar trim, the Bluetooth signal would be completely blocked by the metal of the window frame, causing it to malfunction. Furthermore, considering side-impact safety requirements, the gaps and space in the window frames of most vehicles with framed doors are generally insufficient for installing a Bluetooth module.

[0094] In summary, in vehicles with framed doors, the Bluetooth module is generally located on the front / rear bumper skin, resulting in poor positioning accuracy near the door. Analyzing the structure of framed doors, the only usable space is inside the door handle. However, the door handle typically houses a capacitive sensor module. While users can achieve keyless entry by touching the handle with their key, the Bluetooth module and the capacitive sensor module are two different modules, and only one can be accommodated in the door handle. Therefore, for many vehicles with framed doors, to retain the keyless entry function of the capacitive sensor while improving the positioning accuracy of the Bluetooth module near the door, a Bluetooth module integrating the capacitive sensor function needs to be invented. This would satisfy both functional and performance requirements.

[0095] Therefore, this application provides a Bluetooth module with integrated dual-zone capacitors. This Bluetooth module, installed inside the door handle, improves the Bluetooth positioning accuracy near the door of a framed vehicle while retaining the original keyless entry function. The structure of the Bluetooth module with integrated dual-zone capacitors includes an external module housing, foam, wiring harness, and connectors; and an internal circuit board and potting compound. The internal circuit board mainly houses a Bluetooth chip, Bluetooth antenna, touch chip, electrode plates, flexible circuit board, low-dropout linear regulator, and CAN transceiver. When the Bluetooth module with integrated dual-zone capacitors is installed inside the vehicle door handle, the antenna inside the Bluetooth module will locate the user's phone in real time when the user approaches or moves away from the vehicle with their mobile phone key. This enables automatic unlocking when approaching the vehicle and automatic locking when moving away. If the user disables the automatic unlocking and locking function, they can approach the vehicle with their mobile phone key or physical remote key and touch the capacitive sensing area on the inside of the door handle to unlock the vehicle. When leaving the vehicle, they can touch the capacitive sensing area on the outside of the door handle to lock the vehicle. This solves the technical problem of ineffective vehicle control and achieves effective vehicle control.

[0099] Figure 5 This is a schematic diagram of side B of a circuit board according to an embodiment of this application, as shown below. Figure 5 As shown, it includes: Bluetooth chip 310, Bluetooth antenna 320 and flexible circuit board 350.

[0100] Figure 6 This is a schematic diagram of a Bluetooth module system according to an embodiment of this application, such as... Figure 6 As shown, it includes: a Bluetooth module 10 with integrated dual-zone capacitors, a vehicle domain controller module 20, a mobile phone 30, and a physical remote key 40.

[0101] In this embodiment, the Bluetooth module 10 with integrated dual-zone capacitors is installed inside the vehicle door handle. It supports user touch to achieve keyless entry (unlocking and locking the vehicle) and can also improve the Bluetooth positioning accuracy near the door, enhancing the user's Bluetooth key experience. The Bluetooth module 10 with integrated dual-zone capacitors includes a housing 100, foam 110, potting compound 120, wiring harness 200, connector 210, and circuit board 300.

[0102] Optionally, the housing 100 needs to be adapted to the internal structure of the vehicle door handle 400 and is snapped into the door handle by the limiting rib 410. Foam 110 serves as shock absorber; different thicknesses of foam can be set according to the structure, with 1mm thickness being an option. Potting compound 120, composed of polyurethane, fills the entire module for sealing, meeting waterproof requirements. Wiring harness 200 is soldered at one end to the internal circuit board 300, mating with the housing 100 via a plug 220, and at the other end to the connector 210. The number of wiring harnesses 200 can be customized according to product requirements; the Bluetooth module can have six wiring harnesses 200: one power wire, one ground wire, two CAN wires, one signal wire, and one detection wire. Connector 210 uses an 8-pin waterproof connector (PinInput / Output, abbreviated as PIN) to meet the mounting hole size requirements, waterproof requirements, and wiring harness connection requirements of the door handle frame. The circuit board 300 mainly includes a Bluetooth chip 310, a Bluetooth antenna 320, a touch chip 330, an electrode sheet 340, a flexible circuit board 350, a low-dropout linear regulator 360, and a CAN transceiver 370.

[0103] Optionally, the Bluetooth chip 310 and Bluetooth antenna 320 are used to store and execute programs and receive the Bluetooth signal strength of the user's mobile phone 30 to realize the positioning function of the Bluetooth key; the touch chip 330, electrode plate 340 and flexible circuit board 350 are used for capacitive sensing of the outer area 500 and the inner area 600 and processing of touch signals; the low dropout linear regulator 360 mainly achieves voltage regulation through linear adjustment, thereby providing a stable, low-noise DC voltage output; the CAN transceiver 370 converts the data provided by the Bluetooth chip 310 into electrical signals, and then sends them out through the data bus, while also receiving bus data and transmitting the data to the Bluetooth chip 310.

[0104] Optionally, if the vehicle is near the unlock switch and the user approaches the vehicle door with their mobile phone 30, the distance between the mobile phone and the vehicle is detected by the Bluetooth module 10. When the mobile phone 30 is detected to be in the unlock area outside the vehicle, the Bluetooth module 10 sends an unlock request to the vehicle domain controller module 20, and the vehicle can automatically unlock. If the vehicle is far from the door lock switch and the user carries their mobile phone 30 away from the vehicle door, the Bluetooth module 10 detects the distance between the phone and the vehicle. When the phone 30 is detected to be in the locking area outside the vehicle, the Bluetooth module 10 sends a locking request to the vehicle domain controller module 20, and the vehicle can automatically lock. If the vehicle is near the door lock switch and the user carries their mobile phone 30 or physical remote key 40 to the vicinity of the vehicle door, they can touch the inner area 600 of the Bluetooth module 10. The Bluetooth module 10 will process the capacitive sensing signal and send it to the vehicle domain controller module 20, and the vehicle can unlock. If the vehicle is far from the door lock switch and the user carries their mobile phone 30 or physical remote key 40 out of the vehicle, they can touch the outer area 500 of the Bluetooth module 10. The Bluetooth module 10 will process the capacitive sensing signal and send it to the vehicle domain controller module 20, and the vehicle can lock.

[0105] In this embodiment, by integrating a Bluetooth module with dual-zone capacitance, the Bluetooth positioning accuracy of a vehicle with framed doors near the door can be improved. It also has the keyless entry function of a capacitive sensor. Compared with the original independent Bluetooth module plus a capacitive sensor module, the Bluetooth module with integrated dual-zone capacitance also reduces costs.

[0106] Corresponding to the vehicle control system of the embodiments of this application, a vehicle control method is proposed. Figure 7 This is a flowchart of a vehicle control method according to an embodiment of this application, such as... Figure 7 As shown, the vehicle includes a framed door. The method is applied to a Bluetooth module, which is deployed inside the door handle of the framed door and connected to a controller. The method includes the following steps.

[0107] Step S701: When the target switch of the vehicle is turned on, the location of the mobile terminal is determined based on the detected Bluetooth signal of the mobile terminal; based on the location, a target request is sent to the controller, wherein the target request is responded to by the controller to perform control operations on the vehicle.

[0108] In this embodiment, the Bluetooth module with integrated dual-zone capacitors continuously monitors the target switch status of the vehicle. The target switches include a first type of switch corresponding to unlocking operations (e.g., when the vehicle approaches the unlock switch) and a second type of switch corresponding to locking operations (e.g., when the vehicle moves away from the lock switch). When either target switch is turned on, the Bluetooth module enters a standby state, ready to receive and process Bluetooth signals from the mobile terminal.

[0109] Optionally, when the target switch is on, the Bluetooth antenna in the Bluetooth module with integrated dual-zone capacitors begins scanning the surrounding environment, capturing and analyzing the Bluetooth signal emitted by the mobile terminal. Parameters such as the Bluetooth signal strength, frequency, and time of arrival are used to calculate the precise location of the mobile terminal. Once the Bluetooth signal is detected, the Bluetooth module determines the real-time location of the mobile terminal based on the signal analysis results and determines whether it is within a preset geographical area. For example, by combining the vehicle's geometric model and environmental factors, it determines whether the mobile terminal is in a first geographical area close to the vehicle or a second geographical area far from the vehicle.

[0110] Optionally, the Bluetooth module generates a corresponding control request based on the geographical area where the mobile terminal is located. If the mobile terminal is determined to be located in a first geographical area close to the vehicle, an unlock request is generated; if it is located in a second geographical area far from the vehicle, a lock request is generated.

[0111] Optionally, after receiving the target request from the integration module, the vehicle domain controller module can decide whether to execute the operation indicated in the request based on the vehicle's current state (such as whether the engine is off, whether the doors are closed, etc.) and preset safety rules. If the decision is affirmative, the controller will send a command to the vehicle's actuators (such as door lock motors) to complete the unlocking or locking of the vehicle.

[0112] In step S702, when the target switch is closed, in response to receiving a touch signal in the capacitive sensing area on the door handle, a capacitive sensing signal corresponding to the capacitive sensing area is sent to the controller, wherein the capacitive sensing signal is responded to by the controller to perform control operations on the vehicle.

[0113] In this embodiment, when the target switch is off—that is, both the first type of switch (vehicle approaching the unlock switch) and the second type of switch (vehicle moving away from the lock switch) are in the off state—the first Bluetooth module in the Bluetooth module is used to locate the mobile terminal's position information and does not send unlock or lock requests (i.e., unlock / lock requests) to the controller. After the user touches the capacitive sensing area, the controller can receive the capacitive sensing signal and simultaneously receive the mobile terminal's position information from the first Bluetooth module. Based on the capacitive sensing signal and the mobile terminal's position information, the controller determines whether to perform an unlock or lock operation.

[0114] In other words, when the target switch is off, the controller can perform an unlocking or locking operation after receiving the capacitive sensing signal and the location information of the mobile terminal.

[0115] Optionally, when a user touches the capacitive sensing area, the capacitance change detected by the electrode pads is converted into a capacitive sensing signal. The touch chip is responsible for processing these capacitive sensing signals, including amplification, filtering, and analog-to-digital conversion, to enhance the clarity of the capacitive sensing signal and reduce the impact of external interference. The processed capacitive sensing signal contains specific information about the touch event, such as the timing, intensity, and location of the touch. Once the capacitive sensing signal is successfully triggered, the touch chip can send this signal to the vehicle domain controller module via a designated pin (e.g., a signal line pin) in an 8-pin miniature waterproof connector. The waterproof connector ensures that the quality of signal transmission is not affected even under adverse environmental conditions, thereby guaranteeing the reliability and stability of the vehicle's control system.

[0116] Optionally, after receiving the capacitive sensing signal, the vehicle domain controller module can interpret the user intent behind the signal according to preset logic and rules. If the capacitive sensing signal indicates that the user is touching the first capacitive sensing area on the inside of the door handle, the controller will perform the unlocking operation; conversely, if the user is touching the second capacitive sensing area on the outside, the controller will perform the locking operation.

[0117] Optionally, if both the first type of switch (vehicle near the unlock switch) and the second type of switch (vehicle away from the lock switch) are in the on state, and the first Bluetooth module detects that the mobile terminal is in the first geographical area (unlocked area) or the second geographical area (locked area), it can directly send an unlock request or a lock request to the controller. In this case, it is not necessary to generate a capacitive sensing signal through user touch. After receiving the unlock request or lock request from the first Bluetooth module, the controller can perform the unlock operation or the lock operation.

[0118] In other words, when the target switch is turned on, the first Bluetooth module can send an unlock request or a lock request to the controller when it locates the mobile terminal in the unlocking / locking area. The controller can then respond to the unlock request or lock request and directly perform the unlocking or locking operation.

[0119] In this embodiment, a Bluetooth module is deployed within the door handle of a framed vehicle door and connected to a controller. When the target switch of the vehicle is open, the first Bluetooth module determines the location of the mobile terminal based on the detected Bluetooth signal. Based on the location, a target request is sent to the controller, which responds to the target request and performs control operations on the vehicle. When the target switch is closed, the second Bluetooth module, in response to a touch signal received at the capacitive sensing area on the door handle, sends a capacitive sensing signal corresponding to the capacitive sensing area to the controller, which responds to the capacitive sensing signal and performs control operations on the vehicle. In other words, by integrating a dual-zone capacitive Bluetooth module within the door handle, this application significantly improves the Bluetooth signal reception and processing capabilities near the door without sacrificing the original keyless entry function, thereby improving positioning accuracy and solving the technical problem of ineffective vehicle control, achieving effective vehicle control.

[0120] The above-mentioned method of this application will be further described below.

[0121] As an optional implementation, when the target switch of the vehicle is turned on, the location of the mobile terminal is determined based on the detected Bluetooth signal of the mobile terminal, including: when the target switch is turned on, determining the distance between the mobile terminal and the vehicle based on the detected Bluetooth signal; locating the mobile terminal based on the distance to obtain its location; and sending a target request to the controller based on the location, including: sending a target request corresponding to the geographical area where the location is located to the controller; when the target switch is turned off, in response to receiving a touch signal on the capacitive sensing area of ​​the door handle, sending a capacitive sensing signal corresponding to the capacitive sensing area to the controller, including: when the target switch is turned off, sensing that the capacitive sensing area has received a touch signal, triggering the capacitive sensing signal; detecting the triggered capacitive sensing signal, and sending the detected capacitive sensing signal to the controller.

[0122] In this embodiment, the operation process of the Bluetooth module with integrated dual-zone capacitors in two different states of target switch on and off ensures that the user can efficiently and safely control the vehicle's locking and unlocking functions in both automatic and manual modes.

[0123] Optionally, when the target switch is open—that is, when the target switch (such as the vehicle approaching the unlock switch or the vehicle moving away from the lock switch) is in the open state, preparing to enter the automatic locking / unlocking mode—the Bluetooth module's RSSI or other positioning technologies can be used to detect and analyze the Bluetooth signal emitted by the mobile terminal (such as a mobile phone) to calculate the real-time distance between the mobile terminal and the vehicle. Based on the calculated distance, the geographical area of ​​the mobile terminal can be determined. If the mobile terminal is located in the unlocked area outside the vehicle (the distance to the vehicle is less than a set threshold), the Bluetooth module will send an unlock request to the body domain controller module via the data bus (such as the CAN bus); conversely, if it is located in the locked area (far from the vehicle), it will send a lock request. Upon receiving the request, the controller will execute the corresponding locking / unlocking control operation.

[0124] Optionally, when the target switch is off, touch events in the capacitive sensing area of ​​the door handle can be monitored via electrode pads to prepare for user manual operations. When the user touches the capacitive sensing area on the door handle, the electrode pads capture the capacitance change, triggering a capacitive sensing signal. The touch chip is responsible for detecting the triggered capacitive sensing signal and performing necessary signal processing to ensure signal accuracy and reliability. The processed signal contains information such as the touch area, touch intensity, and touch duration. The processed capacitive sensing signal is sent to the vehicle domain controller module via a waterproof connector. Based on the received signal, the controller identifies the user's intent (unlock or lock) and executes the corresponding control operation.

[0125] In this embodiment, a Bluetooth module is deployed within the door handle of a framed vehicle door and connected to a controller. When the target switch of the vehicle is open, the first Bluetooth module determines the location of the mobile terminal based on the detected Bluetooth signal. Based on the location, a target request is sent to the controller, which responds to the target request and performs control operations on the vehicle. When the target switch is closed, the second Bluetooth module, in response to a touch signal received at the capacitive sensing area on the door handle, sends a capacitive sensing signal corresponding to the capacitive sensing area to the controller, which responds to the capacitive sensing signal and performs control operations on the vehicle. In other words, by integrating a dual-zone capacitive Bluetooth module within the door handle, this application significantly improves the Bluetooth signal reception and processing capabilities near the door without sacrificing the original keyless entry function, thereby improving positioning accuracy and solving the technical problem of ineffective vehicle control, achieving effective vehicle control.

[0126] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties.

[0127] According to an embodiment of this application, a vehicle control device is provided. It should be noted that the vehicle control device can be used to execute the above-described vehicle control method.

[0128] Figure 8 This is a schematic diagram of a vehicle control device according to an embodiment of this application, such as... Figure 8 As shown, the vehicle control device 80 may include a first transmitting unit 81 and a first transmitting unit 82.

[0129] The first transmitting unit 81 is used to determine the location of the mobile terminal based on the detected Bluetooth signal of the mobile terminal when the target switch of the vehicle is turned on; and to send a target request to the controller based on the location, wherein the target request is responded to by the controller to perform control operations on the vehicle.

[0130] The second transmitting unit 82 is used to transmit a capacitive sensing signal corresponding to the capacitive sensing area to the controller in response to receiving a touch signal in the capacitive sensing area on the door handle when the target switch is closed. The capacitive sensing signal is responded to by the controller to perform control operations on the vehicle.

[0131] Optionally, the first sending unit 81 includes: a determining subunit, configured to determine the distance between the mobile terminal and the vehicle based on the detected Bluetooth signal when the target switch is turned on; a positioning subunit, configured to locate the mobile terminal based on the distance to obtain its location; and a first sending subunit, configured to send a target request corresponding to the geographical area to the controller based on the geographical area where the location is located.

[0132] The second transmitting unit 82 includes: a trigger subunit, used to sense a touch signal received in the capacitive sensing area when the target switch is closed, and trigger a capacitive sensing signal; and a second transmitting subunit, used to detect the triggered capacitive sensing signal and send the detected capacitive sensing signal to the controller.

[0133] In the vehicle control device of this embodiment, when the target switch of the vehicle is turned on, the first sending unit 81 determines the location of the mobile terminal based on the detected Bluetooth signal of the mobile terminal; based on the location, a target request is sent to the controller, wherein the target request is responded to by the controller to perform control operations on the vehicle; when the target switch is turned off, the second sending unit 82, in response to receiving a touch signal on the capacitive sensing area on the door handle, sends a capacitive sensing signal corresponding to the capacitive sensing area to the controller, wherein the capacitive sensing signal is responded to by the controller to perform control operations on the vehicle, thereby solving the technical problem of not being able to effectively control the vehicle and achieving the technical effect of effectively controlling the vehicle.
