Watch type car key control method and device and watch type car key

Abstract

The invention relates to a watch type car key control method and device and a watch type car key. The method comprises the steps that when it is detected that the watch type car key is located in a car and a radio frequency signal sent by the car is received, whether a display screen is in a screen-on state or not is detected; if it is detected that the display screen is in the bright screen state, the display screen is controlled to be turned off and enters a forbidden state. When the automobile is in a parking state, a radio-frequency signal is transmitted to the outside so that the watch type automobile key can check the automobile, and after the watch type automobile key receives the radio-frequency signal transmitted by the automobile, the watch type automobile key transmits a signal to the automobile so that the automobile can be in a manipulable state (for example, an automobile machine is started). When the watch-type car key receives the radio frequency signal transmitted by the car, the display screen of the watch-type car key controller is turned off and enters the forbidden state, the interference of the watch-type car key in sending the signal to the car is reduced, and therefore the sensitivity and stability of the watch-type car key in the process of starting the car machine function are improved.

[0037] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with 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.

[0038] In one embodiment, Figure 1 As shown, a watch-type car key control method is provided, and the method is applied to a watch-type car key as an example for explanation. 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 watch-type car key control method includes the following steps:

[0039] Step S110, when it is detected that the watch-type car key is located in the car and a radio frequency signal sent by the car is received, it is detected whether the display screen is in a light-on state.

[0040] The car sends a radio frequency signal to the outside world when it is parked (the car is in a parked state, which at least includes the car doors being locked and the car computer being powered off). The radio frequency signal is used by the watch-type car key to check the existence of the car. When the watch-type car key detects the car, it sends a signal to the car to put the car in a controllable state, for example, opening the door, turning on the car computer, 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. Conversely, 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 car user is inside the vehicle, according to normal logic, when the watch-type car key is in good working order, the signal strength of the radio frequency signal received is the strongest, and the watch-type car key is able to detect the existence of the vehicle. In order to improve the sensitivity and stability of the watch-type car key as a car key function, it is necessary to reduce the interference of the watch-type car key itself to the generated signal. When the display screen is in the bright screen state, it will interfere with the radio frequency signals emitted by the display screen, causing the vehicle to be unable to receive the radio frequency signals emitted by the watch-type car key, thereby making the watch-type car key unable to be used as a car key and unable to control the car, reducing the stability and sensitivity of the watch-type car key when used as a car key.

[0041] It should be noted that the display screen is in the bright screen state means that the display screen is lit and emits light. In one embodiment, the watch-type car key determines whether the display screen is in the bright screen state by detecting the current or voltage of the display screen. In another embodiment, the watch-type car key determines whether the display screen is in the bright screen state by detecting the temperature of the display screen.

[0042] In order to accurately determine whether the watch-type car key is in the car, it can be indirectly determined by determining whether the car user is inside the car (normally, the watch-type car key is worn on the car user's hand), or it can be directly determined whether the watch-type car key is in the car. In order to determine whether the car user is wearing a watch-type car key, in one example, the watch-type car key can be determined by checking whether the car user's biometric information can be collected. If the car user's biometric information can be collected, it is determined that the watch-type car key is worn on the car user. The biometric information can be pulse information, body temperature information, blood pressure information, facial information, etc. The following provides two ways to determine whether the watch-type car key is in the car:

[0043] In one way, Figure 2 As shown, when it is detected that the watch-type car key is located in the car and a radio frequency signal sent by the car is received, in the step of detecting whether the display screen is in a light-on state, the watch-type car key is detected to be located in the car based on the following steps:

[0044] Step S210, obtaining a set of a first geographical location of the watch-type car key and a second geographical location of the car.

[0045] The first geographic location needs to be acquired in real time, that is, the watch-type car key acquires the geographic location of the watch-type car key at the current moment as the first geographic location. Since the size of the car is relatively large, it is impossible to determine whether the watch-type car key is located inside the car by acquiring the geographic location of a point on the car. Therefore, a second geographic location set is acquired, and the second geographic location set includes at least three second geographic locations (a corresponding number of location sensors need to be installed on the car, for example, respectively installed on the car). The acquisition of the second geographic location set of the car can be retrieved from the memory of the watch-type car key (for example, after the car is parked, the car sends the second geographic location set of parking to the watch-type car key, and the watch-type car key stores the second geographic location set, or after the car is parked, the watch-type car key collects the second geographic location set of parking of the car and stores the geographic location), or it can be acquired by the watch-type car key in real time.

[0046] Step S220: If it is determined that the first geographical location is located within the area surrounded by the set of second geographical locations, it is detected that the watch-type car key is located in the car.

[0047] The second geographical locations are sequentially connected to form an area. For example, when there are three second geographical locations, the area formed is a triangular area, and when there are four second geographical locations, the area formed is a quadrilateral area. It is determined whether the first geographical location is within the area formed by the second geographical locations. If the first geographical location is within the area formed by the second geographical locations, it can be determined that the watch-type car key is located in the car.

[0048] In another way, Figure 3 As shown, when it is detected that the watch-type car key is located in the car and a radio frequency signal sent by the car is received, in the step of detecting whether the display screen is in a light-on state, the watch-type car key is detected to be located in the car based on the following steps:

[0049] Step S310, receiving and parsing the detection information sent by the car. In this example, the relevant sensors of the car (thermal imaging sensor, biometric information recognition sensor, temperature sensor, pressure sensor) can be kept in working state to detect relevant information of the car user at any time to 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, facial information, iris information, sound information, temperature information and seat pressure information.

[0050] Step S320: based on the analysis result of the detection information, it is detected that the watch-type car key is located in the car. After obtaining the detection information, the watch-type car key analyzes the detection information. If the detection information contains one or any combination of thermal imaging information, fingerprint information, facial information, iris information, sound information, temperature information and seat pressure information, it can be determined that the watch-type car key is located in the car.

[0051] Step S120, if it is detected that the display screen is in the on state, the display screen is controlled to be turned off and enter the disabled state.

[0052] When the display screen is detected to be in the on state, in order to avoid the influence of the lit display screen on the radio frequency signal it transmits, the display screen is controlled to turn off and enter the disabled state. Among them, the off screen indicates that the backlight of the display screen is turned off, making it in the off state. The disabled state means that the display screen cannot be lit up and woken up by conventional operations on the display screen (for example, touch operation, button operation), that is, when the watch-type car key starts the car machine function, the display screen is disabled, thereby preventing the display screen from being lit up again due to the car user's operation and interfering with the radio frequency signal transmitted by the watch-type car key.

[0053] In some cases, the automatic screen off of the display may fail. To avoid this, in the example where the signal strength of the RF signal sent by the car is greater than or equal to the preset strength, in the example where the moving direction of the watch-type car key is detected, in the example where the hand gesture is detected, and in the example where the signal strength of the RF signal sent by the car is continuously detected, the display cannot automatically turn off and affect the RF signal it sends. In this example, a manual screen off function is added. Figure 4 As shown, the watch-type car key control method includes the steps of:

[0054] Step S410, when it is detected that the watch-type car key is in the car and the radio frequency signal sent by the car is received, it is detected whether the display screen is in a bright screen state. It should be noted that step S410 is the same as the step in the above embodiment, please refer to the description of the corresponding embodiment, and it will not be repeated here.

[0055] Step S420: If it is detected that the display screen is in the on state, the display screen is controlled to be off and enter the disabled state. It should be noted that step S420 is the same as the step in the above embodiment, please refer to the description of the corresponding embodiment, and will not be repeated here.

[0056] Step S430, detect whether the display screen is turned off and enters a disabled state. If the display screen is not turned off within a first preset time period, obtain the operation action.

[0057] It should be noted that the first preset time length can be set as needed, for example, the first preset time length is 10 seconds, the first preset time length is 15 seconds, or the first preset time length is 20 seconds. In one embodiment, the watch-type car key determines whether the display screen is in a bright screen state by detecting the current or voltage of the display screen. In one embodiment, the watch-type car key determines whether the display screen is in a bright screen state by detecting the temperature of the display screen. The operation action is the action of 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.

[0058] Step S440: If the operation action is the first preset action, the display screen is controlled to turn off and enter a disabled state.

[0059] In the 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 the example where the operation action is an action on a key, the first preset action may be, but is not limited to: long pressing the power key, double-clicking the power key, pressing the power key and the page turning key at the same time, etc. When the operation action is detected to be the first preset action, the display screen is forcibly controlled to turn off and enter a disabled state.

[0060] In some usage scenarios, the car user is in the car for rest or other things, and does not need to drive the car. In these cases, the car user has no intention of driving the car. Due to the above steps of the watch-type car key control method of this application, the display screen has been turned off and entered a disabled state. In order for the car user to unlock the display screen and use it normally in these cases, the following methods are provided:

[0061] The first method, if it is detected that the display screen is in the on state, then after the step of controlling the display screen to turn off the screen and enter the disabled state, also includes the steps of:

[0062] If the duration of receiving the radio frequency signal sent by the car exceeds the second preset duration, the display screen is controlled to light up and enter the enabled state. It should be noted that before the car's computer is started, the car will continue to transmit radio frequency signals, so that the watch-type car key can continue to receive the radio frequency signal transmitted by the car. Under normal circumstances, if the car user wants to drive the car, the car computer will be started in a relatively short time. If the car user delays starting the car computer, it means that the car user just wants to rest in the car or do other things, and has no intention of driving the vehicle. For this reason, a second preset duration is set, and the second preset duration can be set according to the average duration of the car user getting in the car and starting the car. For example, the second preset duration is slightly longer than the average duration. If the radio frequency signal sent by the car can still be received after exceeding the second preset duration, it means that the car owner has no intention of driving the car, ensuring that the car user can use the watch function of the watch-type car key to control the display screen to light up and enter the enabled state. It should be noted that the enabled state can receive touch commands and be touched by the car user.

[0063] The second method, such as Figure 5 As shown, if it is detected that the display screen is in the on state, then after the step of controlling the display screen to turn off the screen and enter the disabled state, the step further includes:

[0064] Step S510, before the vehicle computer is started, detect the hand gesture.

[0065] For example, a watch-type car key can detect hand gestures using one or any combination of the following devices: a velocity sensor, a gyroscope, a magnetometer, or a camera. Among them, the acceleration sensor can detect acceleration and gravity 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 a velocity sensor, a gyroscope, or a magnetometer is used to detect hand gestures, the gestures of a hand wearing a watch-type car key can be detected. When a camera is used to detect hand gestures, the gestures of a hand not wearing a watch-type car key can be detected.

[0066] Step S520: If the gesture is a preset gesture, the display screen is controlled to light up and enter an enabled state.

[0067] When the hand gesture detected is a preset gesture, it can be said that the car user has no intention to enter the car, and the display screen is forced to light up and enabled, and the car user wants to unlock the display screen. In an example, the preset gesture can be but is not limited to: rotating the hand, shaking the hand repeatedly, raising the hand, etc. It should be noted that the enabled state can receive touch instructions and be touched by the car user.

[0068] The third method, such as Figure 6As shown, if it is detected that the display screen is in the on state, then after the step of controlling the display screen to turn off the screen and enter the disabled state, the step further includes:

[0069] Step S610: Before the vehicle computer of the vehicle is started, an operation action is detected. 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 it can be an action on a button.

[0070] Step S620, if the operation action is the second preset action, the display screen is controlled to light up and enter the enabled state. When the operation action is the second preset action, it can be said that the car user has no intention of entering the car, and the car user wants to unlock the display screen. In the 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-clicking the display screen, etc. In the 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 key, triple-clicking the power key, pressing the power key and the page turning key at the same time, etc. When it is detected that the operation action is the second preset action, the car user has no intention of entering the car, and the display screen is forced to light up and enabled.

[0071] For some car users, they do not want the watch-type car key to be automatically used as a car key in certain occasions or time periods. Therefore, in one example, when the watch-type car key is detected to be in the car and the radio frequency signal sent by the car is received, before the step of detecting whether the display screen is in the light-on state, the step is also included: receiving a mode switching instruction, and controlling the watch-type car key to perform key mode based on the mode switching instruction. The software of the watch-type car key has a built-in mode selection function, and the car user can switch the working mode of the watch-type car key independently. Specifically, the watch-type car key includes a smart watch mode and a key mode. In the smart watch mode, the watch-type car key is used as a smart watch. In the key mode, the watch-type car key is used as a car key. Among them, the car user can send a mode switching instruction to the watch-type car key through the touch screen, sound or physical button. Thereby, the car user can independently control the watch-type car key to work in which mode, thereby improving the car user's experience with the watch-type car key.

[0072] The watch-type car key control method of the present application includes the following steps: when it is detected that the watch-type car key is located in the car and receives the radio frequency signal sent by the car, it detects whether the display screen is in the light-on state; if it is detected that the display screen is in the light-on state, the display screen is controlled to turn off and enter a disabled state. When the car is in a parked state, a radio frequency signal is transmitted to the outside world so that the watch-type car key can detect the vehicle. After receiving the radio frequency signal transmitted by the car, the watch-type car key sends a signal to the vehicle to put the car in a controllable state (for example, starting the car). When the watch-type car key receives the radio frequency signal transmitted by the car, the display screen of the watch-type car key controller turns off and enters a disabled state, reducing the interference of the signal sent by the watch-type car key to the vehicle, thereby improving the sensitivity and stability of the watch-type car key in realizing the function of starting the car.

[0073] It should be understood that although Figure 1-6 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 1-6 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed 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 executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0074] In one embodiment, a watch-type vehicle key control device is provided, the device comprising:

[0075] A detection module, used for detecting whether the display screen is in a light-on state when detecting that the watch-type car key is in the car and receiving a radio frequency signal sent by the car;

[0076] The control module is used to control the display screen to turn off and enter a disabled state if it is detected that the display screen is in a light-on state.

[0077] The specific definition of the watch-type car key control device can be found in the definition of the watch-type car key control method above, which will not be repeated here. Each module in the above-mentioned watch-type car key control device can be implemented in whole or in part by software, hardware and a combination thereof. The above-mentioned modules can be embedded in or independent of the processor in the computer device in the form of hardware, or can be stored in the memory of the computer device in the form of software, so that the processor can call and execute the operations corresponding to the above modules.

[0078] In one embodiment, a watch-type car key is provided, and its internal structure diagram can be as follows: Figure 7 As shown. The watch-type car key includes a processor, a memory and a display screen connected via a system bus. Among them, the processor of the watch-type car key is used to provide computing and control capabilities.
