Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0039] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.
[0040] The term "module" refers to any known or subsequently developed hardware, software, firmware, artificial intelligence, fuzzy logic, or combination of hardware and / or software code that is capable of performing the functions associated with that element.
[0041] Figure 1 This is a schematic diagram of the buttons for an electric wheelchair in the relevant technology, such as... Figure 1 As shown, related technologies generally use independent buttons or button combinations to enter the self-locking mode. This can be achieved from... Figure 1 As clearly seen, current electric wheelchairs have numerous buttons. When a user needs to enter the self-locking mode, they must locate the button marked "lock" among these buttons, making the operation cumbersome. To improve the button operation experience, this application provides an electric wheelchair control method, an electric wheelchair, and a device. This method enables the user to seamlessly enter the self-locking mode. In this application embodiment, the electric wheelchair is equipped with a joystick, which integrates a sensor. In this method, the sensor collects sensing data; if the sensing data determines that the joystick is in a non-grip state, the wheelchair enters the self-locking mode. In the self-locking mode, pushing the joystick will not rotate the wheelchair.
[0042] To enable seamless entry and exit from the self-locking mode, this application provides an electric wheelchair equipped with a joystick. Exemplarily, the joystick can be located on the armrest of the electric wheelchair; however, those skilled in the art can also place the joystick in other locations on the electric wheelchair as needed, as long as it is convenient for user operation. To determine in real time whether the joystick is in a gripped state, this application integrates a sensor in the joystick so that the sensor can collect sensing data in real time. To control the electric wheelchair, this application provides an electric wheelchair control method. Figure 2 This application provides a schematic diagram of an electric wheelchair control process, which includes: S201: Acquire the sensing data collected by the sensor.
[0043] The electric wheelchair control method provided in this application is applied to an electronic device, which may be a computer (PC), a server, or a controller for an electric wheelchair.
[0044] In self-locking mode, the electric wheelchair will not rotate when the user pushes the joystick. Since users generally do not need to enter self-locking mode while driving the electric wheelchair, and typically move it by controlling the joystick, this embodiment of the application can determine whether to enter self-locking mode by monitoring the state of the joystick.
[0045] In this embodiment of the application, the sensing data collected by the sensor can be acquired in real time, and the state of the joystick can be determined based on the sensing data.
[0046] For example, the sensor can be a temperature sensor, in which case the sensed data collected by the sensor will be temperature data. Of course, those skilled in the art can also configure the sensor to other types of sensors as needed.
[0047] S202: If it is determined from the sensing data that the joystick is in a non-grip state, then a self-locking mode is entered, in which the wheelchair will not rotate when the joystick is pushed.
[0048] After acquiring the sensor data, it can be determined whether the joystick is currently in a gripped or ungripped state. A gripped state means the joystick is being held by a hand; an ungripped state means the joystick is not being held by a hand.
[0049] In this embodiment, if the acquired sensor data determines that the joystick is in a non-grip state, it can be assumed that the joystick is not currently being held by a hand, and the user has no need to control the electric wheelchair's movement by manipulating the joystick. Therefore, the electric wheelchair can be controlled to enter a self-locking mode. When the electric wheelchair enters the self-locking mode, the user will not rotate the wheelchair when pushing the joystick.
[0050] For example, if the sensor integrated into the joystick is a temperature sensor, it can determine whether the currently collected temperature is within the reasonable temperature range corresponding to the human body based on the temperature data collected by the temperature sensor. If not, it can be considered that the joystick is not being held and is in a non-held state, and it can be determined that it has entered the self-locking mode.
[0051] In this embodiment, the wheelchair does not rotate when the joystick is pushed in self-locking mode. To monitor the joystick's status in real time, a sensor is integrated into the joystick. When controlling the electric wheelchair, the sensor collects sensor data. When the sensor data determines that the joystick is not being held, the wheelchair enters self-locking mode. By monitoring whether the joystick is being held, the system determines whether the user needs to control the electric wheelchair by manipulating the joystick. Entering self-locking mode when the sensor data determines that the joystick is not being held allows the user to seamlessly enter self-locking mode.
[0052] To achieve seamless user exit from the self-locking mode, based on the above embodiments, the method in this application embodiment further includes: If the sensor data determines that the joystick is in a gripped state, then exit the self-locking mode.
[0053] In this embodiment of the application, if it is determined from the obtained sensing data that the joystick is in a holding state, it can be considered that the joystick is currently being held by a human hand, and the user has a need to control the movement of the electric wheelchair by manipulating the joystick, and can control the electric wheelchair to exit the self-locking mode.
[0054] For example, if the sensor integrated into the joystick is a temperature sensor, it can determine whether the currently collected temperature is within the reasonable temperature range corresponding to the human body based on the temperature data collected by the temperature sensor. If so, it can be assumed that the joystick is currently being held by a person and is in a holding state, and it can be determined to exit the self-locking mode.
[0055] To further improve the accuracy of electric wheelchair control, based on the above embodiments, in this embodiment, the joystick includes a gripping area, and the sensor is disposed in the gripping area, which is the area that contacts the joystick when the user operates it.
[0056] To ensure accurate detection of sensor data when a user holds the joystick, a gripping area can be provided on the joystick in this embodiment. This gripping area can be understood as the area that contacts the joystick when the user manipulates it.
[0057] To ensure accurate data acquisition, in this embodiment, the sensor can be positioned in the grip area.
[0058] Specifically, Figure 3 This is a schematic diagram of a joystick provided in an embodiment of this application. Figure 3 The large rectangular area can be understood as the joystick of the electric wheelchair, which is connected to the wheelchair. This joystick includes a gripping area. Figure 3 The smaller rectangular areas can be considered the gripping areas. The smaller rectangular areas are located within the larger rectangular areas. Sensors can be placed within these gripping areas.
[0059] To further improve the accuracy of electric wheelchair control, based on the above embodiments, in this application embodiment, the sensor is a biosensor, an infrared sensor, or a pressure sensor.
[0060] To further improve the accuracy of electric wheelchair control, various types of sensors can be incorporated into the joystick in this embodiment. For example, the sensor can be a biosensor, an infrared sensor, or a pressure sensor. Of course, those skilled in the art can select other types of sensors as needed.
[0061] In one possible implementation, if the sensor is a biosensor, the acquired sensing data may include at least one of heart rate, blood oxygen saturation, and body temperature. Of course, those skilled in the art can configure the content of the sensing data as needed.
[0062] When the sensor is a biosensor, in this embodiment of the application, when determining whether the joystick is in a non-grip state based on the sensing data, a standard range of sensing data pre-saved for each type can be obtained.
[0063] Specifically, assuming that sensor data including heart rate and blood oxygen saturation are pre-configured, then we can obtain the pre-saved standard range A for heart rate-type sensor data and the pre-saved standard range B for blood oxygen saturation-type sensor data.
[0064] After obtaining the standard range corresponding to each type of sensing data, it can be determined whether the sensing data collected by the sensor is within the corresponding standard range.
[0065] If it is determined that the acquired sensor data is not all within the corresponding standard range, it can be assumed that the object currently in contact with the joystick is not a human body, and the joystick is in a non-grip state.
[0066] If it is determined that the acquired sensor data are all within the corresponding standard range, then it can be assumed that the joystick is currently in contact with a human body, and the joystick is in a holding state.
[0067] In one possible implementation, if the sensor is an infrared sensor, then when determining whether the joystick is in a non-grip state based on the sensing data, it is possible to determine whether the grip area of the joystick is blocked based on the acquired sensing data.
[0068] If the sensor data determines that the joystick's grip area is not obstructed, then the joystick is currently in an ungripped state.
[0069] If the sensor data determines that the joystick's grip area is blocked, then the joystick is currently in a gripping state.
[0070] In one possible implementation, if a pressure sensor is used, then when determining whether the joystick is in a non-grip state based on the sensing data, it can be determined whether the sensing area of the joystick is pressed based on the sensing data collected by the sensor.
[0071] If the sensor data determines that the grip area of the joystick is not being pressed, it can be assumed that there is no person or object in contact with the joystick, and the joystick is in a non-grip state.
[0072] If the sensor data determines that the grip area of the joystick has been pressed, it can be determined that the joystick is currently in contact with a person or object in the outside world, and that the joystick is in a gripping state.
[0073] To ensure user safety, based on the above embodiments, the method in this application embodiment further includes: When the electric wheelchair is powered on, it enters a self-locking mode.
[0074] To prevent accidental activation by users and potential threats to human safety, this embodiment of the application allows the electric wheelchair to enter a self-locking mode upon startup. In other words, the electric wheelchair automatically enters self-locking mode upon power-on.
[0075] The following is combined Figure 4 The process of controlling an electric wheelchair will be explained. Figure 4 This is a schematic diagram illustrating an electric wheelchair control process provided in an embodiment of this application. Figure 4As shown, when the electric wheelchair is powered on / started, the entire machine can be set to a locked state, i.e., enter a self-locking mode. The biosensor in the wheelchair's joystick collects biometric information in real time. This biometric information is the sensing data described in the above embodiments. After acquiring the biometric signal, it can be determined whether the collected biometric signal is a human signal. If so, it can be determined that the joystick is in a gripping state, and the self-locking mode can be entered, i.e., the locking command is engaged. If not, it can be determined that the joystick is not in a gripping state, and the self-locking mode can be exited, i.e., the entire machine remains locked.
[0076] The electric wheelchair control method provided in this application embodiment can realize intelligent automatic locking and unlocking, allowing users to operate without noticing, avoiding user misoperation, and improving user experience.
