[0047] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0048] In one embodiment, as shown in Figure 1, a watch-style car key control method is provided. Taking the application of this method to a watch-style car key as an example, the watch-style car key includes a display screen. It should be noted that the watch-style car key combines the functions of a smartwatch and a car key. The watch-style car key control method includes the following steps:

[0049] Step S110: When the signal strength of the received radio frequency signal sent by the car is greater than or equal to a preset strength, detect whether the display screen is in a bright state.

[0050] When the car is in an unlocked state (which includes at least locked doors and a powered-off infotainment system), it sends radio frequency (RF) signals to the outside world. These RF signals are used by the watch-style car key to detect the car's presence. When the watch-style car key detects the car, it sends a signal to unlock the doors, enabling keyless entry. As the RF signal travels further, the signal strength received by the watch-style car key gradually decreases. When the car owner attempts to enter the vehicle, the person carrying the watch-style car key approaches the vehicle, and the signal strength of the RF signal received by the watch-style car key gradually increases. A preset strength is set as a criterion. When the signal strength of the RF signal received by the watch-style car key is greater than or equal to this preset strength, it can be determined that the car owner intends to enter the vehicle. It should be noted that the preset strength can be set based on the signal strength when the vehicle generates its RF signal and the distance between the watch-style car key and the vehicle. A higher preset strength indicates a closer car owner, suggesting a stronger intention to enter the vehicle, and thus a more accurate determination.

[0051] The display being on means the screen is lit up. In one method, the watch-style car key determines whether the screen is on by detecting the current or voltage of the display. In another method, it determines whether the screen is on by detecting the temperature of the display. It should be noted that when the display is on, the power supply circuit for the display starts working. When the power supply circuit is working, the boost circuit in the power supply circuit also starts working. The boost circuit generates electromagnetic waves that cause interference. The frequency of these electromagnetic waves is approximately between 10 Hz and 500 MHz. The radio frequency signal emitted by the watch-style car key is low-frequency, typically 125 kHz, which falls within the range of electromagnetic interference generated by the boost circuit. Therefore, when the display is on, the watch-style car key may be unable to achieve keyless entry, or its stability and sensitivity of keyless entry may be reduced. 。 Therefore, when the watch-style car key is about to activate the keyless entry function (the signal strength of the received radio frequency signal sent by the car is greater than or equal to the preset strength), it checks whether the display screen is on in order to control the display screen further.

[0052] Step S120: If the display screen is detected to be on, the display screen is turned off and enters a disabled state.

[0053] Upon detecting that the display is on, to prevent the illuminated display from interfering with its emitted radio frequency signals, the display is controlled to turn off and enter a disabled state. The screen-off indicator turns off the display's backlight, placing it in an off state. The disabled state means that the display cannot be activated by regular operations (e.g., touch or button operations). Specifically, when the keyless entry function is activated using the watch-style car key, the display is disabled to prevent interference with the radio frequency signals emitted by the watch-style car key due to subsequent user actions.

[0054] To more accurately determine the intention of a car user entering the vehicle and avoid accidental operation due to a user merely passing by, the following, but not limited to, methods are provided:

[0055] The first method, as shown in Figure 2, involves controlling the display to turn off and enter a disabled state if the display is detected to be on. This includes the following steps:

[0056] Step S210: If the display screen is detected to be on, the direction of movement of the watch-style car key is detected.

[0057] In one example, the watch-style car key can obtain its real-time geolocation and calculate its direction of movement based on the geolocation at different times. In another example, the watch-style car key can utilize a geomagnetic sensor to determine its direction of movement.

[0058] In step S220, if the direction of movement is towards the car, the control display screen is turned off and enters a disabled state.

[0059] A movement direction pointing towards the car indicates that the user intends to approach the car. In one example, to further increase the accuracy of determining the user's intention to enter the car, if the movement direction is towards the car and remains so for a third preset duration, the display screen will turn off and enter a disabled state. It should be noted that the third preset duration can be set according to actual needs; the longer the third preset duration, the higher the accuracy of the determination.

[0060] In one example, when the signal strength of the received radio frequency signal sent by the car is greater than or equal to a preset strength, the watch-style car key obtains the car's geographical location and the watch-style car key's geographical location. The car's geographical location can be obtained from the watch-style car key's memory (for example, after the car is parked, the car sends its parking geographical location to the watch-style car key, and the watch-style car key stores the geographical location, or after the car is parked, the watch-style car key collects the parking geographical location of the car and stores the geographical location), or the car's geographical location can be collected immediately when the signal strength of the received radio frequency signal sent by the car is greater than or equal to the preset strength.

[0061] The initial direction between the watch-style car key and the car is calculated using the car's and watch-style car key's geographical locations. If the watch-style car key's direction of movement is the same as the initial direction, or if its direction of movement is different from the initial direction but within a reasonable deviation, for example, within ±1 degree, then the initial direction is determined.

[0062] When a car user wants to enter the car, they must continuously move closer to the vehicle, thus constantly shortening the straight-line distance between the user and the car. Therefore, by incorporating the detection of this straight-line distance, it's possible to more accurately determine whether the user intends to enter the car, thereby avoiding accidental operation of the watch-style car key due to misjudgment. Specifically, in this example, the watch-style car key control method also includes the steps of: measuring the straight-line distance from the watch-style car key to the car; and, within the range where the straight-line distance changes from greater than a preset distance to equal to a preset distance, detecting the direction of movement of the watch-style car key in real time; if, within this range, the direction of movement consistently points towards the car, the control display screen is turned off and enters a disabled state.

[0063] It should be noted that the preset distance can be set according to actual needs; the shorter the preset distance, the higher the accuracy of the judgment. The straight-line distance refers to the straight-line distance from the watch-style car key to the car. This straight-line distance can be calculated by the watch-style car key obtaining its current geographic coordinates and the car's geographic coordinates, or it can be obtained through infrared ranging technology or by measuring the straight-line distance.

[0064] In one example, when the signal strength of the received radio frequency signal from the car is greater than or equal to a preset strength, the straight-line distance from the watch-style car key to the car is measured. As the car user moves closer to the car, the straight-line distance between the watch-style car key and the car continuously decreases. Therefore, the straight-line distance undergoes a process of changing from greater than a preset distance to equal to a preset distance. During this process, the direction of movement is continuously detected. If the direction of movement is consistently pointing towards the car, it indicates that the car user intends to enter the car.

[0065] The second method, as shown in Figure 3, involves controlling the display to turn off and enter a disabled state if the display is detected to be on. This includes the following steps:

[0066] Step S310: If the display screen is detected to be on, then the hand gesture is detected.

[0067] For example, a watch-style car key can use one or any combination of the following devices to detect hand gestures: a speed sensor, a gyroscope, a magnetometer, or a camera. The accelerometer can detect acceleration and gravitational acceleration, the gyroscope can detect rotation angle and direction, the magnetometer can detect magnetic field strength and direction, and the camera can detect hand movements. It should be noted that when using a speed sensor, gyroscope, or magnetometer to detect hand gestures, it can be to detect gestures from a hand wearing the watch-style car key. When using a camera to detect hand gestures, it can be to detect gestures from a hand not wearing the watch-style car key. In this example, detecting hand gestures is used to further determine whether the car user intends to enter the vehicle.

[0068] In step S320, if the gesture is the first preset gesture, the display screen is turned off and enters a disabled state.

[0069] When the detected hand gesture is a first preset gesture, it indicates that the car user intends to enter the car. In one example, the first preset gesture may be, but is not limited to: raising a hand, raising a hand and pointing at the car, flipping a hand, etc.

[0070] The third method, as shown in Figure 4, involves controlling the display to turn off and enter a disabled state if the display is detected to be on. This includes the following steps:

[0071] In step S410, if the display screen is detected to be on, the signal strength of the received radio frequency signal sent by the car is continuously detected.

[0072] To further determine whether a car user intends to enter the vehicle, the signal strength of the received radio frequency (RF) signal can be continuously monitored. If the user intends to enter the vehicle, they will approach the car, and the received RF signal strength will increase. If the user does not intend to enter the vehicle, they will move away from the car, and the received RF signal strength will decrease.

[0073] In step S420, if the signal strength gradually increases, the display screen is turned off and enters a disabled state.

[0074] When the signal strength is detected to be continuously increasing, it is determined that the car user intends to enter the car.

[0075] In some cases, the automatic screen-off function may malfunction. To prevent the display from automatically turning off and affecting the emitted radio frequency signal, the following steps are taken: avoiding situations where the received radio frequency signal strength from the car is greater than or equal to a preset strength; avoiding situations where the movement direction of the watch-type car key is detected; avoiding situations where hand gestures are detected; and avoiding situations where the received radio frequency signal strength from the car is continuously detected. In these cases, a manual screen-off function is added. In this example, as shown in Figure 5, the watch-type car key control method includes the following steps:

[0076] Step S510: When the signal strength of the received radio frequency signal sent by the car is greater than or equal to a preset strength, detect whether the display screen is in a lit state. It should be noted that step S510 is the same as the steps in the previous embodiments; please refer to the description of the corresponding embodiments, which will not be repeated here.

[0077] In step S520, if the display screen is detected to be on, the display screen is turned off and enters a disabled state. It should be noted that step S520 is the same as the steps in the previous embodiments; please refer to the description of the corresponding embodiments for details, which will not be repeated here.

[0078] Step S530: Detect whether the display screen is off and in a disabled state. If the display screen is not off within a first preset time period, an operation action is acquired. It should be noted that the first preset time period can be set as needed, for example, a first preset time period of 10 seconds, 15 seconds, or 20 seconds. In one embodiment, the watch-style car key determines whether the display screen is on by detecting the current or voltage of the display screen. In another embodiment, the watch-style car key determines whether the display screen is on by detecting the temperature of the display screen. The operation action is the action taken by the car user on the display screen; for example, it can be an action on the display screen itself or an action on a button.

[0079] In step S540, if the operation is the first preset action, the display screen is turned off and enters the disabled state.

[0080] In examples where the operation is an action on the display screen itself, the first preset action can be, but is not limited to: long-pressing the display screen, completely covering the display screen, or double-tapping the display screen. In examples where the operation is an action on a button, the first preset action can be, but is not limited to: long-pressing the power button, double-tapping the power button, or simultaneously pressing the power button and the page up / down button. When the operation is detected as the first preset action, the display screen is forcibly turned off and enters a disabled state.

[0081] When a car user approaches the vehicle simply to check its exterior, retrieve items placed nearby, or for other reasons, and has no intention of entering the vehicle, the display screen is already off and disabled due to the aforementioned steps of the watch-style car key control method described in this application. To enable the car user to unlock and use the display screen normally in these situations, the following methods are provided:

[0082] The first method, as shown in Figure 6, after the step of controlling the display to turn off and enter a disabled state if the display is detected to be on, also includes the following steps:

[0083] Step S610: Before the car's infotainment system is started, the hand gesture is detected.

[0084] For example, a watch-style car key can use one or any combination of the following devices to detect hand gestures: a speed sensor, a gyroscope, a magnetometer, or a camera. The accelerometer can detect acceleration and gravitational acceleration, the gyroscope can detect rotation angle and direction, the magnetometer can detect magnetic field strength and direction, and the camera can detect hand movements. It should be noted that when using a speed sensor, gyroscope, or magnetometer to detect hand gestures, it can be used to detect gestures from a hand wearing the watch-style car key. When using a camera to detect hand gestures, it can be used to detect gestures from a hand not wearing the watch-style car key.

[0085] In step S620, if the gesture is the second preset gesture, the display screen is turned on and enters the enabled state.

[0086] When the detected hand gesture is the second preset gesture, it indicates that the car user does not intend to enter the vehicle. The display screen is then forcibly illuminated and enabled, indicating the car user intends to unlock the screen. In one example, the second preset gesture could be, but is not limited to: rotating the hand, repeatedly shaking the hand, raising the hand, etc. It should be noted that the enabled state can receive touch commands and be operated by the car user.

[0087] The second method, as shown in Figure 7, after the step of controlling the display to turn off and enter the disabled state if the display is detected to be on, also includes the following steps:

[0088] Step S710: Before the vehicle's infotainment system is started, the operation action is detected. The operation action is the action taken by the vehicle user on the display screen, such as an action on the display screen itself or an action on a button.

[0089] In step S720, if the operation is the second preset action, the display screen is turned on and enters the enabled state.

[0090] When the operation is the second preset action, it indicates that the car user does not intend to enter the car and wants to unlock the display screen. In examples where the operation is an action on the display screen itself, the second preset action can be, but is not limited to: drawing a circle on the display screen, drawing a straight line on the display screen, or triple-tapping the display screen, etc. In examples where the operation is an action on a button, the second preset action can be, but is not limited to: long-pressing the page up / down button, triple-tapping the power button, or pressing the power button and page up / down button simultaneously, etc. When the second preset action is detected, indicating that the car user does not intend to enter the car, the display screen is forcibly illuminated and enabled.

[0091] The third method, as shown in Figure 8, after the step of controlling the display to turn off and enter the disabled state if the display is detected to be on, also includes the following steps:

[0092] In step S810, before the vehicle's infotainment system starts, the signal strength of the received radio frequency (RF) signal transmitted by the vehicle is continuously monitored. To determine whether the vehicle user intends to enter the vehicle, the signal strength of the received RF signal is continuously monitored. If the vehicle user intends to enter the vehicle, the user approaches the vehicle, and the signal strength of the received RF signal increases. If the vehicle user does not intend to enter the vehicle, the user moves away from the vehicle, and the signal strength of the received RF signal decreases.

[0093] In step S820, if the signal strength gradually decreases or remains unchanged within a second preset time period, the display screen is turned on and enters the enabled state.

[0094] When the signal strength gradually decreases, it indicates that the car user has moved away from the vehicle. If it remains constant for a second preset time, it indicates that the car user is either stationary or rotating around the car at a constant distance. In both cases, the car user has no intention of entering the vehicle, and the display screen is forcibly illuminated and activated.

[0095] The watch-style car key control method of this application involves the following steps: when the signal strength of the received radio frequency signal sent by the car is greater than or equal to a preset strength, it detects whether the display screen is on; if the display screen is detected to be on, it controls the display screen to turn off and enter a disabled state. When the car is in an unlocked state, it transmits radio frequency signals to the outside world so that the watch-style car key can detect the vehicle, and then the watch-style car key sends a signal to the vehicle to unlock the door. When the watch-style car key receives the radio frequency signal transmitted by the car, the display screen of the watch-style car key controller turns off and enters a disabled state, reducing interference from the signal sent by the watch-style car key to the vehicle, thereby improving the sensitivity and stability of the watch-style car key when implementing the keyless entry function.

[0096] It should be understood that although the steps in the flowcharts of Figures 1-8 are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some of the steps in Figures 1-8 may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the sub-steps or stages of other steps.

[0097] In one embodiment, a watch-style car key control device is provided, comprising:

[0098] The detection module is used to detect whether the display screen is on when the signal strength of the received radio frequency signal sent by the car is greater than or equal to a preset strength.

[0099] The control module is used to turn off the display screen and disable it if it detects that the display screen is on.

[0100] Specific limitations regarding the watch-style car key control device can be found in the above description of the watch-style car key control method, and will not be repeated here. Each module in the aforementioned watch-style car key control device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in or independent of the processor in a computer device, or stored in the memory of a computer device as software, so that the processor can call and execute the corresponding operations of each module.

[0101] In one embodiment, a watch-style car key is provided, the internal structure of which can be shown in Figure 9. The watch-style car key includes a processor, a memory, and a display screen connected via a system bus. The processor provides computing and control capabilities. The memory includes a non-volatile storage medium and internal memory. The non-volatile storage medium stores an operating system and computer programs. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage medium. The computer program is executed by the processor to implement a watch-style car key control method. The display screen controlled by the watch-style car key can be a liquid crystal display (LCD) or an e-ink display.

[0102] Those skilled in the art will understand that the structure shown in Figure 9 is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the watch-type car key control applied thereto. The specific watch-type car key control may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements.

[0103] In one embodiment, a watch-style car key is provided, including a display screen, a memory, and a processor. The processor is connected to both the display screen and the memory. The memory stores a computer program, and the processor executes the computer program to perform the following steps:

[0104] When the signal strength of the received radio frequency signal sent by the car is greater than or equal to the preset strength, the system detects whether the display screen is on.

[0105] If the screen is detected to be on, the screen will be turned off and disabled.

[0106] In one embodiment, the processor, when executing a computer program, also performs the following steps:

[0107] If the display screen is detected to be on, the direction of movement of the watch-style car key is detected.
