[0038] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] In one embodiment, as Figure 1 shown, a method for controlling a watch-type car key is provided. Taking the application of this method to a watch-type car key as an example for description, the watch-type car key includes a display screen. It should be noted that the watch-type car key combines the functions of a smart watch and a car key. The method for controlling a watch-type car key includes the following steps:

[0040] Step S110, when it is detected that the watch-type car key is inside the vehicle and a radio frequency signal sent by the vehicle is received, detect whether the display screen is in the lit state.

[0041] When the vehicle is in a parked state (the vehicle being in a parked state at least includes the vehicle doors being locked and the vehicle head unit being powered off), it sends a radio frequency signal to the outside. This radio frequency signal is used for the watch-type car key to check the presence of the vehicle. When the watch-type car key detects the vehicle, it sends a signal to the vehicle to make the vehicle in a state where it can be controlled, such as opening the vehicle doors, turning on the vehicle head unit, etc. As the propagation distance of the radio frequency signal increases, the signal strength of the radio frequency signal that the watch-type car key can receive will gradually weaken. On the contrary, as the propagation distance of the radio frequency signal decreases, the signal strength of the radio frequency signal that the watch-type car key can receive will gradually increase. When the vehicle user is inside the vehicle, according to normal logic, when the watch-type car key is in good condition, the signal strength of the radio frequency signal it receives is the strongest, and the watch-type car key can detect the presence of the vehicle. In order to improve the sensitivity and stability of the watch-type car key when used as a car key function, it is necessary to reduce the interference of the watch-type car key itself on the transmitted signal. When the display screen is in the lit state, it will interfere with the radio frequency signal it emits outward, resulting in the vehicle being unable to receive the radio frequency signal emitted by the watch-type car key, so that the watch-type car key cannot be used as a car key and cannot control the vehicle with the watch-type car key, reducing the stability and sensitivity of the watch-type car key when used as a car key.

[0042] It should be noted that the display screen being in the lit state means that the display screen is lit and emits light. In one way, the watch-type car key judges whether the display screen is in the lit state by detecting the current or voltage of the display screen. In one way, the watch-type car key judges whether the display screen is in the lit state by detecting the temperature of the display screen.

[0043] To accurately determine whether a watch-type vehicle key is inside the vehicle, it can be indirectly determined by judging whether the vehicle user is inside the vehicle (normally, the watch-type vehicle key is worn on the hand of the vehicle user), or directly by determining whether the watch-type vehicle key is inside the vehicle. To determine that the vehicle user wears a watch-type vehicle key, in one example, the watch-type vehicle key can be judged by checking whether the biological information of the vehicle user can be collected. If the biological information of the vehicle user can be collected, it is judged that the watch-type vehicle key is worn on the vehicle user. The biological information can be pulse information, body temperature information, blood pressure information, face information, etc. The following provides two ways to judge whether the watch-type vehicle key is in the vehicle:

[0044] In one way, as Figure 2 shown, in the step of detecting whether the display screen is in the lit state when it is detected that the watch-type vehicle key is inside the vehicle and a radio frequency signal sent by the vehicle is received, the following steps are used to detect that the watch-type vehicle key is inside the vehicle:

[0045] Step S210, obtain the first geographical location of the watch-type vehicle key and the second geographical location set of the vehicle.

[0046] The first geographical location needs to be obtained in real time, that is, the watch-type vehicle key obtains the geographical location of the watch-type vehicle key at the current moment as the first geographical location. Since the volume of the vehicle is relatively large, obtaining the geographical location of a single point on the vehicle cannot determine whether the watch-type vehicle key is inside the vehicle. Therefore, a second geographical location set is obtained. The second geographical location set contains at least three second geographical locations (corresponding numbers of position sensors need to be installed on the vehicle. For example, they are installed on the vehicle respectively). To obtain the second geographical location set of the vehicle, the obtaining can be from the memory of the watch-type vehicle key (for example, after the vehicle parks, the vehicle sends the second geographical location set of the parking location to the watch-type vehicle key, and the watch-type vehicle key stores this second geographical location set, or after the vehicle parks, the watch-type vehicle key collects the second geographical location set of the vehicle's parking location and stores this geographical location), or it can be obtained in real time by the watch-type vehicle key.

[0047] Step S220, if it is judged that the first geographical location is within the area enclosed by the second geographical location set, it is detected that the watch-type vehicle key is inside the vehicle.

[0048] Connect the second geographical locations in sequence to enclose an area. For example, when there are three second geographical locations, the enclosed area is a triangular area; when there are four second geographical locations, the enclosed area is a quadrilateral area. Judge whether the first geographical location is within the area enclosed by the second geographical location set. If the first geographical location is within the area enclosed by the second geographical location set, it can be judged that the watch-type vehicle key is inside the vehicle.

[0049] In another way, as Figure 3 shown, in the step of detecting whether the display screen is in the lit state when it is detected that the watch-type vehicle key is inside the vehicle and a radio frequency signal sent by the vehicle is received, the following steps are used to detect that the watch-type vehicle key is inside the vehicle:

[0050] Step S310, receive and analyze the detection information sent by the vehicle. In this example, relevant sensors of the vehicle (thermal imaging sensor, biometric identification sensor, temperature sensor, pressure sensor) can be kept working all the time to detect relevant information of the vehicle user at any time and form detection information. In one example, the detection information includes at least one or any combination of the following information: thermal imaging information, fingerprint information, face information, iris information, voice information, temperature information, and seat pressure information.

[0051] Step S320, based on the analysis result of the detection information, detect that the watch-type vehicle key is inside the vehicle. After obtaining the detection information, the watch-type vehicle key analyzes the detection information. If the detection information contains one or any combination of thermal imaging information, fingerprint information, face information, iris information, voice information, temperature information, and seat pressure information, it can be determined that the watch-type vehicle key is inside the vehicle.

[0052] Step S120, if it is detected that the display screen is in the lit state, control the display screen to turn off the screen and enter the disabled state.

[0053] When it is detected that the display screen is in the lit state, in order to avoid the lit display screen affecting the radio frequency signal it emits, control the display screen to turn off the screen and enter the disabled state. Among them, turning off the screen means turning off the backlight of the display screen to make it in the off state. The disabled state means that the display screen cannot be lit and woken up by using conventional operations on the display screen (for example, touch operation, button operation). That is, when the watch-type vehicle key starts the vehicle machine function, the display screen is disabled, so as to avoid the display screen being lit by the vehicle user's repeated operations and interfering with the radio frequency signal emitted by the watch-type vehicle key.

[0054] In some cases, the display screen may malfunction when automatically turning off the screen. In the example of avoiding the signal strength of the radio frequency signal sent by the vehicle received being greater than or equal to the preset strength, in the example of detecting the moving direction of the watch-type vehicle key, in the example of detecting the hand gesture, and in the example of continuously detecting the signal strength of the radio frequency signal sent by the vehicle received, the display screen cannot automatically turn off the screen and affect the radio frequency signal it emits. Add a manual screen-off function. In this example, as Figure 4 shown, the watch-type vehicle key control method includes the steps:

[0055] Step S410, when it is detected that the watch-type vehicle key is inside the vehicle and a radio frequency signal sent by the vehicle is received, detect whether the display screen is in the lit state. It should be noted that step S410 is the same as the steps in the foregoing embodiments. Please refer to the descriptions of the corresponding embodiments for correspondence, and details will not be repeated here.

[0056] Step S420, if it is detected that the display screen is in the lit state, then control the display screen to turn off and enter the disabled state. It should be noted that step S420 is the same as the steps in the foregoing embodiments. Please refer to the descriptions of the corresponding embodiments for correspondence, and details will not be repeated here.

[0057] Step S430, detect whether the display screen turns off and enters the disabled state. If the display screen does not turn off within the first preset duration, obtain an operation action.

[0058] It should be noted that the first preset duration can be set as needed. For example, the first preset duration is 10 seconds, the first preset duration is 15 seconds, or the first preset duration is 20 seconds. In one way, the watch-type vehicle key determines whether the display screen is in the lit state by detecting the current or voltage of the display screen. In one way, the watch-type vehicle key determines whether the display screen is in the lit state by detecting the temperature of the display screen. The operation action is an action of the vehicle user on the display screen. For example, it can be an action on the display screen itself or an action on a button.

[0059] Step S440, if the operation action is the first preset action, then control the display screen to turn off and enter the disabled state.

[0060] In an example where the operation action is an action on the display screen itself, the first preset action may be, but is not limited to: long pressing the display screen, fully covering the display screen, or double clicking the display screen, etc. In an example where the operation action is an action on a button, the first preset action may be, but is not limited to: long pressing the power button, double clicking the power button, simultaneously pressing the power button and the page turning button, etc. When it is detected that the operation action is the first preset action, force the display screen to turn off and enter the disabled state.

[0061] In some usage scenarios, the vehicle user is inside the vehicle to rest or for other things and does not need to drive the vehicle. In these cases, the vehicle user has no intention of driving the vehicle. Due to the foregoing steps of the watch-type vehicle key control method of the present application, the display screen has turned off and entered the disabled state. In order for the vehicle user to unlock the display screen and use the display screen normally in these cases, the following several methods are provided:

[0062] The first method, after the step of controlling the display screen to turn off and enter the disabled state if it is detected that the display screen is in the lit state, further includes the steps:

[0063] If the duration of the received radio frequency signal sent by the vehicle exceeds the second preset duration, control the display screen to turn on and enter the enabled state. It should be noted that before the in-vehicle computer of the vehicle starts, the vehicle will continuously emit radio frequency signals, so that the watch-type vehicle key can continuously receive the radio frequency signals sent by the vehicle. Under normal circumstances, if the vehicle user wants to drive the vehicle, the in-vehicle computer will be started within a relatively short period of time. If the vehicle user does not start the in-vehicle computer for a long time, it means that the vehicle user just wants to rest or do other things in the vehicle and has no intention of driving the vehicle. Therefore, the second preset duration is set, and this second preset duration can be set according to the statistically average duration for vehicle users to get in the vehicle and start the vehicle. For example, the second preset duration is slightly longer than the average duration. If the radio frequency signal sent by the vehicle can still be received after exceeding the second preset duration, it means that the vehicle owner has no intention of driving the vehicle, ensuring that the vehicle user can use the watch function of the watch-type vehicle key, controlling the display screen to turn on and enter the enabled state. It should be noted that the enabled state can receive touch commands and be touched and operated by the vehicle user.

[0064] The second method is as Figure 5 shown. After the step of controlling the display screen to turn off and enter the disabled state if it is detected that the display screen is in the on state, the following steps are further included:

[0065] Step S510: Before the in-vehicle computer of the vehicle starts, detect the hand gesture.

[0066] For example, the watch-type vehicle 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, etc. Among them, the acceleration sensor can detect acceleration and gravitational acceleration, the gyroscope can detect the rotation angle and direction, the magnetometer can detect the magnetic field strength and direction, and the camera can detect hand movements. It should be noted that when using the speed sensor, gyroscope, and magnetometer to detect hand gestures, it can be to detect the hand gesture of the hand wearing the watch-type vehicle key. When using the camera to detect hand gestures, it can be to detect the hand gesture of the hand not wearing the watch-type vehicle key.

[0067] Step S520: If the gesture is a preset gesture, control the display screen to turn on and enter the enabled state.

[0068] When the detected hand gesture is a preset gesture, it can indicate that the vehicle user has no intention of getting into the vehicle, force the display screen to light up and be enabled, and the vehicle user wants to unlock the display screen. In one example, the preset gesture can be, but is not limited to: rotating the hand, waving the hand repeatedly, raising the hand, etc. It should be noted that the enabled state can receive touch commands and be touched and operated by the vehicle user.

[0069] The third method is as Figure 6As shown, after detecting that the display screen is in the lit state and controlling the display screen to turn off and enter the disabled state, the method further includes the steps of:

[0070] Step S610, before the in-vehicle infotainment (IVI) system of the vehicle is started, detect an operation action. The operation action is an action of the vehicle user on the display screen. For example, it can be an action on the display screen itself or an action on a button.

[0071] Step S620, if the operation action is a second preset action, control the display screen to turn on and enter the enabled state. When the operation action is a second preset action, it can indicate that the vehicle user has no intention of entering the vehicle and wants to unlock the display screen. In an example where the operation action 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 an example where the operation action is an action on a button, the second preset action can be, but is not limited to, long-pressing the page-turning button, triple-tapping the power button, pressing the power button and the page-turning button simultaneously, etc. When it is detected that the operation action is a second preset action, since the vehicle user has no intention of entering the vehicle, the display screen is forced to light up and enabled.

[0072] The method for controlling a watch-type vehicle key in this application includes the following steps: when it is detected that the watch-type vehicle key is inside the vehicle and a radio frequency signal sent by the vehicle is received, detect whether the display screen is in the lit state; if it is detected that the display screen is in the lit state, control the display screen to turn off and enter the disabled state. When the vehicle is in the parked state, it will emit a radio frequency signal to the outside so that the watch-type vehicle key can detect the vehicle. After the watch-type vehicle key receives the radio frequency signal sent by the vehicle, the watch-type vehicle key sends a signal to the vehicle to make the vehicle in a state where it can be controlled (for example, starting the IVI system). When the watch-type vehicle key receives the radio frequency signal sent by the vehicle, the controller of the watch-type vehicle key turns off the display screen and enters the disabled state, reducing the interference of the watch-type vehicle key when sending a signal to the vehicle, thereby improving the sensitivity and stability of the watch-type vehicle key when realizing the function of starting the IVI system.

[0073] It should be understood that although Figures 1 - 6 the steps in the flowchart are shown in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear indication in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders.

[0077] For the specific limitations of the wristwatch-type vehicle key control device, reference can be made to the limitations on the wristwatch-type vehicle key control method in the above text, which will not be elaborated here. Each module in the above wristwatch-type vehicle key control device can be implemented in whole or in part by software, hardware, and their combination. The above modules can be embedded in the processor in the computer device in hardware form or be independent of it, or be stored in the memory in the computer device in software form, so that the processor can call and execute the operations corresponding to the above modules.
