Description

[0002] With the widespread adoption of smartphones and the development of Bluetooth technology, mobile Bluetooth keys are gradually replacing traditional physical keys, providing car owners with the convenience of unlocking, locking, and starting their vehicles without physical contact. Vehicle Bluetooth mobile phone keys achieve near-field communication between the phone and the vehicle through Bluetooth wireless technology. The Bluetooth anchor point on the vehicle scans the phone's Bluetooth broadcast signal and calculates the distance between the phone key and the vehicle based on the Bluetooth signal strength using an algorithm, thereby determining whether to allow seamless unlocking, locking, and starting of the vehicle. However, Bluetooth signals are significantly affected by the environment. In different environments, at the same distance, the strength of the Bluetooth signal received by the vehicle from the phone varies greatly. This leads to a discrepancy between the predicted distance calculated by the vehicle based on signal strength and the actual distance in the real environment, resulting in significant differences in unlocking / locking distances under different conditions. This instability in Bluetooth key use leads to a poor user experience. Summary of the Invention

[0022] Please see Figure 1 This is a structural diagram illustrating an application scenario of a preferred embodiment of this application. Based on wireless communication technology, when a user needs to operate the vehicle 100, such as unlocking / locking or remote ignition, the user can control the vehicle 100 to perform the corresponding operation through the terminal device 200. It is understood that this application does not limit the specific type of the terminal device 200. For example, it can be a mobile phone, tablet computer, personal computer (PC), smart screen, artificial intelligence (AI) speaker, or wearable terminal device such as a smartwatch, or a key system built into other devices such as a remote key or key card. The terminal device 200 can bind to the vehicle 100 through a server (not shown) to control the vehicle 100 to perform the aforementioned operations.

[0023] Please refer to the following: Figure 2This is a flowchart illustrating a preferred embodiment of the vehicle unlocking / locking method of this application. The vehicle unlocking / locking method can be applied to a vehicle 100. Understandably, the vehicle 100 includes a vehicle unlocking / locking device 1, an in-vehicle Bluetooth device 2, a vehicle controller 3, and an in-vehicle satellite device 4. The vehicle controller 3 can acquire vehicle status and condition information through an in-vehicle communication system (TelematicBox, T-Box) and upload these parameters to the backend of a Telematics Service Provider (TSP). It can also receive commands issued by the backend and send back execution results. Based on this, remote control functions can be extended to mobile apps, smart keys, etc. The T-Box generally refers to an intelligent in-vehicle terminal in a vehicle networking system, which communicates directly with the vehicle's CAN bus.

[0024] Step S201: Establish a Bluetooth communication connection between vehicle 100 and terminal device 200.

[0025] In at least one embodiment of this application, the vehicle 100 can establish a communication connection with at least one terminal device 200 in a stopped state or in a running state. The vehicle 100 can establish a Bluetooth communication connection with the terminal device 200 in different ways. In a first way, when stopped, the vehicle 100 broadcasts a Bluetooth signal to its surroundings in real time or periodically. When the terminal device 200 receives the Bluetooth signal broadcast by the vehicle 100, it determines that the terminal device 200 has entered the Bluetooth communication range of the vehicle 100, and a Bluetooth communication connection is established between the vehicle 100 and the terminal device 200. When the terminal device 200 does not receive the Bluetooth signal broadcast by the vehicle 100, it determines that the terminal device 200 has not entered the Bluetooth communication range of the vehicle 100, and the vehicle 100 cannot establish a Bluetooth communication connection with the terminal device 200. In an alternative approach, terminal device 200 broadcasts Bluetooth signals to its surroundings in real time or periodically. When a nearby vehicle 100 receives the Bluetooth signal broadcast by terminal device 200, vehicle 100 sends a Bluetooth response signal back to terminal device 200. Upon receiving the Bluetooth response signal, terminal device 200 is determined to be within Bluetooth communication range of vehicle 100, and a Bluetooth communication connection is established between vehicle 100 and terminal device 200. If terminal device 200 does not receive a Bluetooth response signal, it is determined to be outside Bluetooth communication range of vehicle 100, and a Bluetooth communication connection between vehicle 100 and terminal device 200 is not established.

[0026] Step S202: Output a Bluetooth connection indication signal.

[0027] In at least one embodiment of this application, when the vehicle 100 and the terminal device 200 successfully establish a Bluetooth communication connection, the vehicle Bluetooth device 2 outputs a Bluetooth connection indication signal to the vehicle satellite device 4.

[0028] Step S203: When the vehicle 100 is in the target state, wake up the vehicle-mounted satellite device 4 of the vehicle 100.

[0029] In at least one embodiment of this application, the target state includes an unstarted state and a parked state. The vehicle controller 3 can determine whether the vehicle 100 is in the target state by using brake gear information and the engine status information of the vehicle 100. Specifically, when the engine of the vehicle 100 is in the unstarted state, the vehicle controller 3 recognizes that the vehicle 100 is in the unstarted state and outputs a wake-up signal to the on-board satellite device 4 to wake up the on-board satellite device 4; when the vehicle 100 is in the P gear, the vehicle controller 3 recognizes that the vehicle 100 is in the parked state and outputs a wake-up signal to indicate both the started state and the parked state.

[0030] Step S204: Obtain visible satellite information using vehicle-mounted satellite device 4.

[0031] In at least one embodiment of this application, the vehicle-mounted satellite device 4 searches for and acquires visible satellite information. Visible satellite information includes the number of visible satellites and satellite signal strength. The vehicle-mounted satellite device 4 can utilize either the Global Positioning System (GPS) or the BeiDou satellite system to achieve the corresponding functions. GPS is a system that uses GPS positioning satellites to perform real-time positioning and navigation globally. GPS is a satellite navigation system with omnidirectional, all-weather, all-time, and high-precision capabilities, providing global users with low-cost, high-precision three-dimensional position, velocity, and accurate timing navigation information.

[0032] Step S205: Determine the target environment where vehicle 100 is located based on visible satellite information, and match the corresponding calculation parameters based on the target environment.

[0033] Please see Figure 3 This is a detailed flowchart of step S205 provided in the embodiments of this application.

[0034] Step S2051: Determine whether the number of visible satellites is greater than or equal to the number threshold.

[0035] In at least one embodiment of this application, the quantity threshold is 3. In other embodiments, the quantity threshold may be adjusted as needed.

[0036] Step S2052: When the number of visible satellites is greater than or equal to the number threshold, determine whether the satellite signal strength is greater than the signal strength threshold.

[0037] In at least one embodiment of this application, the signal strength threshold can be -130 dBm. In other embodiments, the signal strength threshold can be adjusted as needed.

[0038] In step S2053, when the satellite signal strength is greater than the signal strength threshold, the vehicle 100 is determined to be in the first target environment and matched with the first calculation parameters.

[0039] In at least one embodiment of this application, the first target environment is an open-air environment.

[0040] Step S2054: When the number of visible satellites is less than the number threshold or the satellite signal strength is less than or equal to the signal strength threshold, the vehicle 100 is determined to be in the second target environment and the second calculation parameters are matched.

[0041] In at least one embodiment of this application, the second target environment is a garage environment.

[0042] In at least one embodiment of this application, the vehicle 100 stores a correspondence table between target environments and calculation parameters. The calculation parameters are Bluetooth signal-related parameters, including a reference signal strength indicator (RSSI) value and a path loss index. The reference signal strength is the Received Signal Strength Indication (RSSI) value at a preset distance from the vehicle 100. In at least one embodiment of this application, the preset distance is 1 meter. When the vehicle 100 is determined to be in a first target environment, a first RSSI value and a first path loss index are acquired as matching first calculation parameters; when the vehicle 100 is determined to be in a second target environment, a second RSSI value and a second path loss index are acquired as matching second calculation parameters. The first RSSI value is greater than the second RSSI value; the first path loss index is less than the second path loss index. That is, the RSSI value of the Bluetooth signal in an open-air environment is greater than the RSSI value in a garage environment; the loss of the Bluetooth signal in an open-air environment is less than the loss of the Bluetooth signal in a garage environment.

[0043] In at least one embodiment of this application, the first calculation parameter and the second calculation parameter can be obtained by fitting multiple experimental data.

[0044] Taking the reference signal strength as an example, when the vehicle 100 is in the first target environment, the signal strength indication value at a preset distance from the vehicle 100 is measured multiple times and the average value is taken as the first reference signal strength indication value; when the vehicle 100 is in the second target environment, the signal strength indication value at a preset distance from the vehicle 100 is measured multiple times and the average value is taken as the second reference signal strength indication value.

[0045] Taking the path loss index as an example, when vehicle 100 is in the first target environment, the relative distance calculation formula uses a first reference signal strength indicator value as the reference signal strength. Multiple measured signal strength indicator values ​​are obtained by measuring the signal strength indicator values ​​at different distances from vehicle 100. Each measured signal strength indicator value is substituted into the relative distance calculation formula to derive multiple measured path loss indices. The average of these multiple measured path loss indices is calculated as the first path loss index. When vehicle 100 is in the second target environment, the relative distance calculation formula uses a second reference signal strength indicator value as the reference signal strength indicator value. Multiple measured signal strength indicator values ​​are obtained by measuring the signal strength indicator values ​​at different distances from vehicle 100. Each measured signal strength indicator value is substituted into the relative distance calculation formula to derive multiple measured path loss indices. The average of these multiple measured path loss indices is calculated as the second reference signal strength indicator value. In at least one embodiment of this application, the measured signal strength indicator values ​​correspond to Bluetooth signal strength indicator values ​​at distances of 1 meter, 2 meters, 2 meters, and 10 meters from vehicle 100, respectively.

[0046] Step S206: Transmit the received terminal Bluetooth information.

[0047] In at least one embodiment of this application, the vehicle-mounted Bluetooth device 2 can receive and transmit terminal Bluetooth signals broadcast in real time by the terminal device 200 to the vehicle controller 3. In other embodiments, the vehicle-mounted Bluetooth device 2 can also receive and transmit terminal Bluetooth signals broadcast by the terminal device 200 at predetermined time intervals to the vehicle controller 3. The predetermined time interval can be set as needed.

[0048] Step S207: Calculate the relative distance between vehicle 100 and terminal device 200 based on terminal Bluetooth information and matched calculation parameters.

[0049] In at least one embodiment of this application, the relative distance can be calculated according to the following formula.

[0050] in, The relative distance between vehicle 100 and terminal equipment 200. This is the reference signal strength indication value corresponding to the target environment. This refers to the Bluetooth signal strength indication value received by vehicle 100 under the target environment. The path loss index that matches the target environment.

[0051] Step S208: Control vehicle 100 to perform corresponding control operations based on relative distance and unlocking / locking strategy.

[0052] Please refer to the following: Figure 4 This is a detailed flowchart of step S208.

[0053] Step S2081: Determine whether the relative distance is less than or equal to the unlocking threshold.

[0054] Step S2082: When the relative distance is less than or equal to the unlocking threshold, perform the unlocking control operation.

[0055] Step S2083: When the relative distance is greater than the unlocking threshold, determine whether the relative distance is greater than or equal to the locking threshold.

[0056] Step S2084: When the relative distance is greater than or equal to the locking threshold, execute the locking control operation.

[0057] Step S2085: When the relative distance is greater than the unlocking threshold and less than the locking threshold, perform a monitoring and control operation to monitor the changing trend of the relative distance.

[0058] In at least one embodiment of this application, the vehicle controller 3 sends an unlock command to a door actuator (not shown) as a corresponding unlock control operation. The unlock control operation may include unlocking the driver's side door of the vehicle 100 or unlocking all doors. The unlock control operation may also include other operations such as starting the engine of the vehicle 100. The vehicle controller 3 sends a lock command to the door actuator as a corresponding lock control operation. The lock control operation may include locking all doors of the vehicle 100. The vehicle controller 3 performs a monitoring control operation to monitor the changing trend of relative distance.

[0059] Step S209: Control the vehicle-mounted satellite signal to enter sleep mode.

[0060] In at least one embodiment of this application, the vehicle controller 3 generates a sleep signal to the vehicle satellite device 4 when it detects that the vehicle 100 is in the off state or in the P gear. The vehicle satellite device 4 switches to the sleep state according to the sleep signal, thereby reducing the power consumption of the vehicle 100 when it is off or parked.

[0061] Based on the aforementioned vehicle unlocking and locking method, when the terminal device 200 is within the Bluetooth sensing range of the vehicle 100, the onboard satellite device 4 is activated. The onboard satellite device 4 determines the environment in which the vehicle 100 is located. The calculation parameters in the distance calculation formula are adjusted according to the different environments in which the vehicle 100 is located, thereby improving the accuracy of relative distances under different conditions and optimizing the user experience. Simultaneously, utilizing visible satellite information reduces the probability of the vehicle 100 failing to unlock or experiencing delayed unlocking when performing unlocking control operations under different environments, thus improving the security of the vehicle 100.

[0062] Please see Figure 5 This is a schematic diagram of the vehicle unlocking / locking device 1 according to at least one embodiment of this application. In at least one embodiment of this application, the vehicle unlocking / locking device 1 can be built into the vehicle controller 3 of the vehicle 100. The vehicle unlocking / locking device 1 can communicate with the vehicle Bluetooth device 2 and the vehicle satellite device 4. The vehicle unlocking / locking device 1 includes an environment recognition module 10, a parameter matching module 20, a calculation module 30, and a control module 40.

[0063] The environment recognition module 10 is used to determine the target environment where the vehicle 100 is located based on visible satellite information.

[0064] In at least one embodiment of this application, visible satellite information is searched and acquired using a vehicle-mounted satellite device 4. Visible satellite information includes the number of visible satellites and their signal strength. The vehicle-mounted satellite device 4 can utilize either the Global Positioning System (GPS) or the BeiDou satellite system to achieve the corresponding functions. GPS is a system that uses GPS positioning satellites to perform real-time positioning and navigation globally. GPS is a satellite navigation system with omnidirectional, all-weather, all-time, and high-precision capabilities, providing global users with low-cost, high-precision three-dimensional position, velocity, and accurate timing navigation information.

[0065] The environment identification module 10 determines whether the number of visible satellites is greater than or equal to a number threshold. In at least one embodiment of this application, the number threshold is 3. In other embodiments, the number threshold can be adjusted as needed. When the number of visible satellites is greater than or equal to the number threshold, the environment identification module 10 further determines whether the satellite signal strength is greater than a signal strength threshold. In at least one embodiment of this application, the signal strength threshold can be -130dBm. In other embodiments, the signal strength threshold can be adjusted as needed. When the satellite signal strength is greater than the signal strength threshold, the environment identification module 10 determines that the vehicle 100 is in a first target environment. In at least one embodiment of this application, the first target environment is an open-air environment. When the number of visible satellites is less than the number threshold or the satellite signal strength is less than or equal to the signal strength threshold, the environment identification module 10 determines that the vehicle 100 is in a second target environment. In at least one embodiment of this application, the second target environment is a garage environment.

[0066] The parameter matching module 20 is used to match calculation parameters according to the target environment. Specifically, the parameter matching module 20 is used to match a first calculation parameter according to a first target environment or a second calculation parameter according to a second target environment.

[0067] In at least one embodiment of this application, the vehicle 100 stores a correspondence table between target environments and calculation parameters. The calculation parameters are Bluetooth signal-related parameters, including a reference signal strength indicator (RSSI) value and a path loss index. The reference signal strength is the Received Signal Strength Indication (RSSI) value at a preset distance from the vehicle 100. In at least one embodiment of this application, the preset distance is 1 meter. When the vehicle 100 is determined to be in a first target environment, a first RSSI value and a first path loss index are acquired as matching first calculation parameters; when the vehicle 100 is determined to be in a second target environment, a second RSSI value and a second path loss index are acquired as matching second calculation parameters. The first RSSI value is greater than the second RSSI value; the first path loss index is less than the second path loss index. That is, the RSSI value of the Bluetooth signal in an open-air environment is greater than the RSSI value in a garage environment; the loss of the Bluetooth signal in an open-air environment is less than the loss of the Bluetooth signal in a garage environment.

[0068] In at least one embodiment of this application, the first calculation parameter and the second calculation parameter can be obtained by fitting multiple experimental data.

[0069] Taking the reference signal strength as an example, when the vehicle 100 is in the first target environment, the signal strength indication value at a preset distance from the vehicle 100 is measured multiple times and the average value is taken as the first reference signal strength indication value; when the vehicle 100 is in the second target environment, the signal strength indication value at a preset distance from the vehicle 100 is measured multiple times and the average value is taken as the second reference signal strength indication value.

[0070] Taking the path loss index as an example, when vehicle 100 is in the first target environment, the relative distance calculation formula uses a first reference signal strength indicator value as the reference signal strength. Multiple measured signal strength indicator values ​​are obtained by measuring the signal strength indicator values ​​at different distances from vehicle 100. Each measured signal strength indicator value is substituted into the relative distance calculation formula to derive multiple measured path loss indices. The average of these multiple measured path loss indices is calculated as the first path loss index. When vehicle 100 is in the second target environment, the relative distance calculation formula uses a second reference signal strength indicator value as the reference signal strength indicator value. Multiple measured signal strength indicator values ​​are obtained by measuring the signal strength indicator values ​​at different distances from vehicle 100. Each measured signal strength indicator value is substituted into the relative distance calculation formula to derive multiple measured path loss indices. The average of these multiple measured path loss indices is calculated as the second reference signal strength indicator value. In at least one embodiment of this application, the measured signal strength indicator values ​​correspond to Bluetooth signal strength indicator values ​​at distances of 1 meter, 2 meters, 2 meters, and 10 meters from vehicle 100, respectively.

[0071] The calculation module 30 is used to calculate the relative distance between the vehicle 100 and the terminal device 200 based on the terminal Bluetooth information and the matched calculation parameters.

[0072] In at least one embodiment of this application, the relative distance can be calculated according to the following formula.

[0073] in, The relative distance between vehicle 100 and terminal equipment 200. This is the reference signal strength indication value corresponding to the target environment. This refers to the Bluetooth signal strength indication value received by vehicle 100 under the target environment. The path loss index that matches the target environment.

[0074] The control module 40 is used to control the vehicle 100 to perform corresponding control operations based on the relative distance and the locking / unlocking strategy. The control module 40 determines whether the relative distance is less than or equal to an unlocking threshold. When the relative distance is less than or equal to the unlocking threshold, the control module 40 performs an unlocking control operation. When the relative distance is greater than the unlocking threshold, the control module 40 further determines whether the relative distance is greater than or equal to a locking threshold. When the relative distance is greater than or equal to the locking threshold, the control module 40 performs a locking control operation. When the relative distance is greater than the unlocking threshold but less than the locking threshold, the control module 40 performs a monitoring control operation to monitor the changing trend of the relative distance.

[0075] In at least one embodiment of this application, the control module 40 sends an unlock command to a door actuator (not shown) as a corresponding unlock control operation. The unlock control operation may include unlocking the driver's side door of the vehicle 100 or unlocking all doors. The unlock control operation may also include other operations such as starting the engine of the vehicle 100. The control module 40 sends a lock command to the door actuator as a corresponding lock control operation. The lock control operation may include locking all doors of the vehicle 100. The control module 40 performs a monitoring control operation to monitor the changing trend of relative distance.

[0076] The control module 40 is also used to control the vehicle-mounted satellite signal to enter a sleep state. In at least one embodiment of this application, the control module 40 generates a sleep signal to the vehicle-mounted satellite device 4 when it detects that the vehicle 100 is in a ignition off or parked position. The vehicle-mounted satellite device 4 switches to a sleep state according to the sleep signal, thereby reducing the power consumption of the vehicle 100 when it is in a ignition off or parked state.

[0077] Based on the aforementioned vehicle unlocking / locking device 1, when the terminal device 200 is within the Bluetooth sensing range of the vehicle 100, the onboard satellite device 4 is activated. The onboard satellite device 4 determines the environment in which the vehicle 100 is located. The calculation parameters in the distance calculation formula are adjusted according to the different environments in which the vehicle 100 is located, thereby improving the accuracy of relative distances under different conditions and optimizing the user experience. Simultaneously, utilizing visible satellite information reduces the probability of the vehicle 100 failing to unlock or experiencing delayed unlocking when performing unlocking control operations under different environments, thus improving the security of the vehicle 100.

[0078] Please see Figure 6 This is a block diagram of a vehicle 100 according to at least one embodiment of this application. It is understood that this application does not limit the type of vehicle 100; for example, it can be a plug-in hybrid electric vehicle or a hybrid electric vehicle.

[0079] Vehicle 100 includes a vehicle unlocking / locking device 1, an in-vehicle Bluetooth device 2, a vehicle controller 3, an in-vehicle satellite device 4, a processor 5, a memory 6, and a communication interface 7. The vehicle unlocking / locking device 1, the in-vehicle Bluetooth device 2, the vehicle controller 3, the in-vehicle satellite device 4, the processor 5, the memory 6, and the communication interface 7 can be connected via a T-Box to complete communication between them.
