Description

[0001] This invention is a divisional application of application number 202010239513.3, filed on March 30, 2020, entitled "Electronic Device". Technical Field

[0002] This invention relates to the field of vehicle control, and more particularly to a vehicle control method and system. Background Technology

[0003] Currently, most automotive reversing radars used in the industry are ultrasonic radars, which install multiple ultrasonic probes in the rear bumper to detect surrounding objects and distances. Solutions for child detection inside the vehicle include cameras or millimeter-wave radar, which install probes in the rear roof or behind the front seats to detect any living beings in the rear seats. Each of these two functions requires a specific set of detection equipment to perform the detection.

[0004] As the demands on vehicle functionality increase, the number of devices and wiring harnesses on vehicles is also growing to achieve these functions, which brings about issues in component layout and styling during the vehicle design process. For example, ultrasonic radar and millimeter-wave radar require different transceiver equipment and separate wiring harness branches, with diverse signals, requirements, and processing technologies; external ultrasonic radar on the bumper can also affect the vehicle's appearance, while internal millimeter-wave radar can also influence the interior design.

[0005] While achieving various functions, how to reduce vehicle hardware configuration and lower costs is a topic worthy of in-depth study by those skilled in the art. Summary of the Invention

[0006] This invention provides a vehicle control method and system that can reduce vehicle hardware configuration while realizing functions such as key control, reversing reminder, and in-vehicle biometric detection, thereby minimizing costs.

[0007] On one hand, the present invention provides a vehicle control system, which includes a first detection module, a second detection module, a key positioning device, a biometric detection device, and a reversing reminder device. The first detection module is connected to the key positioning device and the biometric detection device, respectively, and the second detection module is connected to the key positioning device and the reversing reminder device, respectively.

[0008] The first detection module includes a first radar antenna for implementing an in-vehicle biological detection mode and a first communication antenna for implementing a first key positioning mode; the second detection module includes a second radar antenna for implementing an external environment detection mode and a second communication antenna for implementing a second key positioning mode.

[0009] In the in-vehicle biometric detection mode, the first detection module is used to provide an in-vehicle biometric detection signal to the biometric detection device. In the first key positioning mode, the first detection module is used to provide a first positioning signal of the smart key to the key positioning device. In the external environment detection mode, the second detection module is used to provide an external environment detection signal to the reversing reminder device. In the second key positioning mode, the second detection module is used to provide a second positioning signal of the smart key to the key positioning device.

[0010] The first detection module switches between the in-vehicle biometric detection mode and the first key positioning mode based on the vehicle's locked state, while the second detection module switches between the second key positioning mode and the external environment detection mode based on the vehicle's locked state.

[0011] Another aspect of the present invention provides a vehicle control method for a vehicle control system, the vehicle control system including a first detection module, a second detection module, a key positioning device, a biometric detection device, and a reversing reminder device. The first detection module is connected to the key positioning device and the biometric detection device, respectively, and the second detection module is connected to the key positioning device and the reversing reminder device, respectively. The first detection module includes a first radar antenna for implementing an in-vehicle biometric detection mode and a first communication antenna for implementing a first key positioning mode. The second detection module includes a second radar antenna for implementing an external environment detection mode and a second communication antenna for implementing a second key positioning mode. The vehicle control method includes:

[0012] Determine the vehicle's locked status;

[0013] Based on the vehicle's locking status, the first detection module is controlled to switch between the in-vehicle biometric detection mode and the first key positioning mode, and the second detection module is controlled to switch between the second key positioning mode and the external environment detection mode.

[0014] The detection signal is acquired using the first detection module and the second detection module;

[0015] Based on the acquired detection signal, the key positioning device, the biometric detection device, and the reversing reminder device are triggered to process data in order to control the vehicle.

[0016] The vehicle control method and system provided by this invention have the following beneficial effects:

[0017] The present invention integrates a first radar antenna for implementing an in-vehicle biometric detection mode and a first communication antenna for implementing a first key positioning mode in the first detection module, and integrates a second radar antenna for implementing an external environment detection mode and a second communication antenna for implementing a second key positioning mode in the second detection module. The first detection module can switch between the in-vehicle biometric detection mode and the first key positioning mode according to the vehicle's locking status, and the second detection module can switch between the second key positioning mode and the external environment detection mode according to the vehicle's locking status, thereby realizing key positioning, biometric detection, and reversing reminder functions based on the first and second detection modules.

[0018] Unlike existing technologies that implement key positioning, biometric detection, and reversing warning functions through completely independent hardware settings, location arrangements, and control logic, the first and second detection modules of this invention reuse the hardware and location settings of the antenna module in the key positioning system of existing vehicles. A radar antenna is integrated into the internal antenna module of the original key positioning system, enabling the integrated first detection module to both locate the smart key and detect in-vehicle biometric information. Similarly, a radar antenna is integrated into the external antenna module of the original key positioning system, enabling the integrated second detection module to both locate the smart key and detect external environmental information. Furthermore, through logic control, the three functions of key positioning, biometric detection, and reversing warning are achieved through a single set of signal acquisition hardware and location settings. This eliminates the need for additional hardware and location setup costs, saving costs and improving the vehicle's aesthetics. Attached Figure Description

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention 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 the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] Figure 1 This is a schematic diagram of a vehicle control system provided in an embodiment of the present invention. Please refer to [link / reference]. Figure 1 The vehicle control system includes a first detection module 10, a second detection module 20, a key positioning device 30, a biometric detection device 40, and a reversing warning device 50. The first detection module 10 is connected to both the key positioning device 30 and the biometric detection device 40, and the second detection module 20 is connected to both the key positioning device 30 and the reversing warning device 50. Preferably, there are multiple first detection modules 10 and multiple second detection modules 20.

[0031] Each first detection module 10 includes a first radar antenna for implementing an in-vehicle biometric detection mode, a first communication antenna for implementing a first key positioning mode, and a first switching device. In the in-vehicle biometric detection mode, the first detection module provides an in-vehicle biometric detection signal to the biometric detection device 40; in the first key positioning mode, the first detection module provides a first positioning signal of the smart key to the key positioning device 30; the first switching device switches between operating in the in-vehicle biometric detection mode and the first key positioning mode according to the vehicle's locking state.

[0032] Each second detection module 20 includes a second radar antenna for implementing an external environment detection mode, a second communication antenna for implementing a second key positioning mode, and a second switching device. In the external environment detection mode, the second detection module provides an external environment detection signal to the reversing warning device 50; in the second key positioning mode, the second detection module provides a second positioning signal of the smart key to the key positioning device 30; the second switching device switches between operating in the second key positioning mode and the external environment detection mode according to the vehicle's locking state.

[0033] The key positioning device 30 is used to determine the vehicle's locking status, which includes a locked state and an unlocked state.

[0034] When the vehicle is locked, the first switching device activates the first radar antenna and disables the first communication antenna, putting the first detection module into in-vehicle biological detection mode. The second switching device activates the second communication antenna and disables the second radar antenna, putting the second detection module into second key positioning mode. The first detection module acquires biological detection signals from organisms inside the vehicle and sends these signals to a biological detection device. The biological detection device determines the presence of a living organism inside the vehicle based on the biological detection signals and sends an alarm message based on the determination result. The second detection module acquires the first positioning signal from the smart key and sends it to a key positioning device. The key positioning device calculates a first distance between the smart key and the vehicle based on the first positioning signal, compares this first distance with a first preset distance, and controls the vehicle based on the comparison result.

[0035] In practical applications, the first detection module in biometric detection mode is mainly used to detect whether there are children inside the vehicle. When the biometric detection device determines that there is a child inside the vehicle based on the biometric detection signal, it can send a warning message to the vehicle's associated devices, or trigger an audible and visual alarm through in-vehicle devices, or forcibly block the key to lock the vehicle. When the smart key is located outside the vehicle, the second detection module receives the frequency emitted by the smart key's controller through the second communication antenna to generate a first positioning signal. The key positioning device analyzes the location of the smart key based on the first positioning signal, calculates the first distance between the vehicle and the smart key based on the location of the smart key and the current location of the vehicle. When the first distance is less than a first preset distance, the vehicle door is opened, and the vehicle is in an unlocked state. When the first distance is not less than the first preset distance, the vehicle remains locked, and no vehicle control operation is performed. The first preset distance is preferably 1.5 meters.

[0036] When the vehicle is unlocked, the first switching device activates the first communication antenna and disables the first radar antenna, putting the first detection module in the first key positioning mode. The second switching device activates the second radar antenna and disables the second communication antenna, putting the second detection module in the external environment detection mode. The first detection module acquires the second positioning signal of the smart key and sends it to the key positioning device. The key positioning device calculates the second distance between the smart key and the vehicle based on the second positioning signal, compares the second distance with a second preset distance, and controls the vehicle based on the comparison result. The second detection module acquires the environmental detection signal of the external environment of the vehicle and sends it to the reversing reminder device. The reversing reminder device determines whether there are obstacles within a preset range at the rear of the vehicle based on the environmental detection signal and sends reversing reminder information based on the determination result.

[0037] When the vehicle is unlocked, the first detection module receives a frequency signal from the smart key controller via the first communication antenna, generating a second positioning signal. The key positioning device analyzes the smart key's position based on the second positioning signal and calculates a second distance between the vehicle and the smart key based on the smart key's position and the vehicle's current position. When the second distance is less than a second preset distance, it is determined that the smart key is inside the vehicle, and the vehicle is put into start mode. When the second distance is not less than the second preset distance, it is determined that the smart key is outside the vehicle, and no vehicle control operation is performed. The first preset distance is preferably 0 meters.

[0038] In one feasible embodiment, the first detection module and the second detection module are selected as UWB (Ultra Wideband) antenna modules.

[0039] Figure 2 This is a flowchart illustrating a vehicle control method provided in an embodiment of the present invention. Figure 2The vehicle control method shown is used in a vehicle control system, which includes a first detection module, a second detection module, a key positioning device, a biometric detection device, and a reversing warning device. The first detection module is connected to both the key positioning device and the biometric detection device, and the second detection module is connected to both the key positioning device and the reversing warning device. The first detection module includes a first radar antenna for implementing an in-vehicle biometric detection mode, a first communication antenna for implementing a second key positioning mode, and a first switching device. The second detection module includes a second radar antenna for implementing an external environment detection mode, a second communication antenna for implementing the first key positioning mode, and a second switching device. Please refer to [link to relevant documentation]. Figure 2 The vehicle control method includes:

[0041] The vehicle's locking status includes both locked and unlocked states.

[0042] S203: Based on the vehicle's locking status, control the first detection module to switch between the in-vehicle biometric detection mode and the second key positioning mode, and control the second detection module to switch between the first key positioning mode and the external environment detection mode.

[0043] Preferably, the first detection module and the second detection module are UWB antenna modules.

When the vehicle is unlocked, the first detection module acquires a second positioning signal from the internal key, and the second detection module acquires an environmental detection signal from the external environment.

[0050] S305: The first detection module acquires the biological detection signal of the organism inside the vehicle, and the second detection module acquires the first positioning signal of the smart key.

[0051] S307: The biological detection device receives the biological detection signal sent by the first detection module, determines whether there is a living organism in the vehicle based on the biological detection signal, and sends an alarm message based on the determination result; the key positioning device receives the first positioning signal sent by the second detection module, calculates the first distance between the smart key and the vehicle based on the first positioning signal, compares the first distance with the first preset distance, and controls the vehicle based on the comparison structure.

[0052] In the biometric detection mode, the first detection module primarily detects the presence of children inside the vehicle. When the biometric detection device determines the presence of a child based on the biometric signal, it can send a warning message to associated vehicle devices, trigger an audible and visual alarm via in-vehicle equipment, or forcibly lock the vehicle by blocking the key. When the smart key is located outside the vehicle, the second detection module receives the frequency emitted by the smart key's controller via the second communication antenna to generate a first positioning signal. The key positioning device analyzes the smart key's position based on the first positioning signal and calculates a first distance between the vehicle and the smart key based on the smart key's position and the vehicle's current position. When the first distance is less than a first preset distance, the vehicle door is unlocked. When the first distance is not less than the first preset distance, the vehicle remains locked, and no vehicle control operations are performed. The first preset distance is preferably 1.5 meters.

[0053] Figure 4 This is a flowchart illustrating the vehicle control method in the unlocked state provided in an embodiment of the present invention. Please refer to... Figure 4 ,include:

[0054] S401: Confirm that the vehicle's locked state is now unlocked.

[0055] S403: The first switching device enables the first detection module to be in the second key positioning mode by enabling the first communication antenna and disabling the first radar antenna; the second switching device enables the second detection module to be in the vehicle external environment detection mode by enabling the second radar antenna and disabling the second communication antenna.

[0056] S405: The first detection module acquires the second positioning signal of the smart key, and the second detection module acquires the environmental detection signal of the vehicle's external environment.

[0057] S407: The key positioning device receives the second positioning signal sent by the first detection module, calculates the second distance between the smart key and the vehicle based on the second positioning signal, compares the second distance with the second preset distance, and controls the vehicle based on the comparison result; the reversing reminder device receives the environmental detection signal sent by the second detection module, determines whether there is an obstacle within a preset range at the rear of the vehicle based on the environmental detection signal, and sends a reversing reminder message based on the determination result.

[0058] Specifically, when the vehicle is unlocked, the first detection module receives a frequency signal from the smart key controller via the first communication antenna, generating a second positioning signal. The key positioning device analyzes the smart key's position based on the second positioning signal and calculates a second distance between the vehicle and the smart key based on the smart key's position and the vehicle's current position. When the second distance is less than a second preset distance, it is determined that the smart key is inside the vehicle, and the vehicle is put into start mode. When the second distance is not less than the second preset distance, it is determined that the smart key is outside the vehicle, and no vehicle control operation is performed. The first preset distance is preferably 0 meters.

[0059] In this embodiment of the invention, a first radar antenna for implementing an in-vehicle biometric detection mode and a first communication antenna for implementing a first key positioning mode are integrated in the first detection module, and a second radar antenna for implementing an external environment detection mode and a second communication antenna for implementing a second key positioning mode are integrated in the second detection module. The first detection module can switch between the in-vehicle biometric detection mode and the first key positioning mode according to the vehicle's locking status, and the second detection module can switch between the second key positioning mode and the external environment detection mode according to the vehicle's locking status, thereby realizing key positioning, biometric detection, and reversing reminder functions based on the first and second detection modules.

[0060] Unlike existing technologies that implement key positioning, biometric detection, and reversing warning functions through completely independent hardware settings, location arrangements, and control logic, the first and second detection modules of this invention reuse the hardware and location settings of the antenna module in the key positioning system of existing vehicles. A radar antenna is integrated into the internal antenna module of the original key positioning system, enabling the integrated first detection module to both locate the smart key and detect in-vehicle biometric information. Similarly, a radar antenna is integrated into the external antenna module of the original key positioning system, enabling the integrated second detection module to both locate the smart key and detect external environmental information. Furthermore, through logic control, the three functions of key positioning, biometric detection, and reversing warning are achieved through a single set of signal acquisition hardware and location settings. This eliminates the need for additional hardware and location setup costs, saving costs and improving the vehicle's aesthetics.

[0061] The vehicle control system embodiments provided in this invention are based on the same inventive concept as the vehicle control method embodiments.

[0062] Figure 5 This is a schematic diagram of a detection module installed on a vehicle according to an embodiment of the present invention. Please refer to... Figure 5 Existing vehicle key positioning systems include internal antenna modules and external antenna modules. In the figure, 1 is the internal antenna module located inside the vehicle's headliner facing inwards, and 2 and 3 are external antenna modules located at the rear of the vehicle facing outwards. According to the present invention, a radar antenna is integrated into the internal antenna module to obtain a first detection module, enabling the first detection module to both locate the smart key and detect child information inside the vehicle. A radar antenna is integrated into the external antenna module to obtain a second detection module, enabling the second detection module to both locate the smart key and detect information about the external environment.

[0063] Figure 6 This is a schematic diagram of the structure of the switching detection module operating mode under the locked state provided in an embodiment of the present invention. Figure 7 This is a structural diagram illustrating the switching of the detection module's operating mode in the unlocked state, as provided in an embodiment of the present invention. Please refer to [link / reference]. Figure 6 and Figure 7 In the diagram, UWB antenna module 1 belongs to the first detection module, while UWB antenna modules 2 and 3 both belong to the second detection module.

[0064] When the vehicle is locked and not in use, the external key location function and the internal child detection function need to be activated. UWB antenna module 1 activates the radar antenna for child detection, while simultaneously disabling the communication antenna to disable the internal key location function. UWB antenna modules 2 and 3 activate their communication antennas for external key location, while simultaneously disabling the radar antenna to disable the rear parking radar function.

[0065] When the vehicle is unlocked, the functions that need to be activated are the in-vehicle key location function and the rear parking radar function. UWB antenna module 1 disables the child detection function by turning off the radar antenna, while simultaneously activating the communication antenna for in-vehicle key location. UWB antenna modules 2 and 3 disable the external key location function by turning off their communication antennas, while simultaneously activating the rear parking radar function.

[0066] When the vehicle is locked or unlocked, the UWB antenna module interacts with the key positioning device, biometric detection device, or reversing reminder device. For details of the data interaction process, please refer to the above method embodiments.
