Description

Technical Field

[0001] The present invention relates to the field of automatic driving technology, and in particular to a vehicle window lifting and lowering control method, device and computer program product. Background Art

[0002] Currently, car window glass lifting and lowering are mainly carried out by manual operation buttons and voice control.

[0003] The control method of the manual operation button is that when the switch button is pressed, the controller receives a signal to control the operation of the glass lifter motor to drive the window glass down; when the switch button is pulled, the controller receives a signal to control the motor to run in the reverse direction to drive the window glass up to close the window. When the vehicle is driving, it is not easy for the driver to observe the rear window, so it is not easy to control the opening. In addition, when the switch button is pressed, the motor drives the window glass to rise and fall. The height of the glass rise and fall per unit time is quantitative, so the glass rise and fall position is determined by the length of time the button is stopped. Since the pressing time is not easy to grasp, the window glass opening may not be the expected opening, so it is necessary to press the button multiple times to adjust, and the human-computer interaction experience is poor.

[0004] The voice control method is that when the controller collects the voice signal of opening or closing the window, it compares the voice signal with the window position information, and then controls the motor to drive the window glass to rise and fall. The voice control method requires the collection of voice information and the comparison of the voice signal defined by the system. The voice signal set by the system is fixed. The collected voice information needs to be relatively clear and accurate, and the conversion into the operation of the glass lifting motor and the glass lifting is also quantitative, so the window opening cannot be adjusted arbitrarily. Summary of the invention

[0015] When the vehicle window is fully closed, if a lateral force from the inside of the vehicle to the outside of the vehicle and a vertical upward force acting on the vehicle window glass are detected, no control signal is generated and the vehicle window glass does not move upward.

[0016] Preferably, if only one of the lateral force and the vertical force acting on the vehicle window glass from the inside of the vehicle to the outside of the vehicle is detected, no control signal is generated and the vehicle window glass does not perform lifting movement.

[0017] Preferably, if the detection signal of the pressure sensor assembly is interrupted, no control signal is generated and the vehicle window glass does not perform lifting and lowering movements.

[0018] Preferably, when detecting the force and direction applied by the user to the vehicle window glass, the method further comprises:

[0019] Synchronously timing the force action time;

[0020] According to a preset time-height mapping relationship table, the force action time is converted into a corresponding window glass lifting height, and the window glass lifting height is used as one of the control parameters to generate the control signal;

[0021] The window lifter motor rotates forward or reversely according to the lifting height of the window glass, so that the window glass is lifted or lowered to a height corresponding to the force action time.

[0022] Preferably, after the vehicle window glass is raised or lowered to a certain height, the method further comprises:

[0023] The window glass opening is calculated based on the lifting height of the window glass and the calibrated stroke of the window glass from fully open to fully closed, and the window glass opening is displayed in real time at a preset position.

BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0034] Figure 1 The present invention is a flowchart of a window lifting and lowering control method according to an embodiment of the present invention.

[0035] Figure 2 It is a schematic diagram of the implementation architecture of an embodiment of the present invention.

[0036] Figure 3 It is a specific flow chart of a window lifting and lowering control method according to an embodiment of the present invention. DETAILED DESCRIPTION

[0037] The following descriptions of the embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention may be implemented.

[0038] Please refer to Figure 1 As shown, the first embodiment of the present invention provides a window lifting control method, comprising the following steps:

[0039] Detect the force and direction applied by the user to the window glass and obtain the current opening status of the window;

[0040] Generate a control signal based on the detected force and direction and the current opening status of the window;

[0041] The window lifter motor is controlled to rotate forward or reverse according to the control signal, thereby driving the vehicle window glass to move up and down.

[0042] It can be seen from the above steps that the present invention can determine the user's intention to raise or lower the window and implement it by detecting the force and direction applied to the window glass and the current opening status of the window. Compared with the existing solutions, it can reduce frequent operation adjustments, greatly improve the efficiency of window lifting and lowering, and enhance the comfort and convenience of driving and riding.

[0043] Specifically, please combine Figure 2 , Figure 3 As shown, in the embodiment of the present invention, a pressure sensor assembly is arranged at the window lift bracket. When the vehicle is powered on, the pressure sensor assembly can detect the pressure and direction applied by the user when touching the window glass. Specifically, when the user touches the window glass and swipes upward or downward, the pressure sensor assembly can detect the lateral force F1 (force directed from the inside of the vehicle to the outside of the vehicle) exerted on the window glass, and can also detect the vertical force F2 (upward or downward force) exerted on the window glass.

[0044] The pressure sensor assembly transmits the force signals F1 and F2 to the domain controller, which processes information such as the direction and magnitude of the force. When the force values ​​of F1 and F2 are both in the calibration range, it determines whether the window needs to be raised or lowered in combination with the current opening status of the window, and then converts it into a control signal for the window lifter motor to control the rotation direction and speed of the motor. The calibration value of the lateral force F1 must be directional, pointing from inside the car to outside the car, and the calibration value must not be zero to prevent people outside the car from touching the glass to raise or lower it. The vertical force F2 is set to a positive value when the force is upward and a negative value when the force is downward, and the calibration value is not zero. The motor speed is the set value to ensure that the window glass lifting speed is not too fast or too slow.

[0045] (1) When the window is partially open:

[0046] When the user touches the window glass and swipes upward, the domain controller receives the force signal (lateral force from inside the car to outside and vertical force upward) and makes a logical judgment. If it determines that the window needs to be raised, it will generate a control signal to control the window lifter motor to drive the window glass to move upward.

[0047] When the user touches the window glass and swipes downward, the domain controller receives the force signal (lateral force from inside the car to outside and vertical downward force) and makes a logical judgment (whether the lateral force and vertical upward force are both within the preset calibration range), determines that the window needs to be lowered, and generates a control signal to control the window lifter motor to drive the window glass to move downward;

[0048] (2) When the windows are fully closed:

[0049] When the user touches the window glass and swipes downward, the domain controller receives the force signal (lateral force from inside the car to outside and vertical downward force) and makes a logical judgment (whether the lateral force and vertical downward force are both within the preset calibration range), determines that the window needs to be lowered, and generates a control signal for the window glass to be lowered, and controls the window lifter motor to drive the window glass to move downward;

[0050] When the user touches the window glass and swipes upward, the domain controller receives the force signal (lateral force from inside the car to outside and vertical force upward) and makes a logical judgment. If it determines that the window does not need to be raised or lowered, it will no longer generate a control signal and the window glass will not move upward.

[0051] (3) When the domain controller receives only one force signal:

[0052] When the domain controller only receives the force signal of the lateral force F1 or the vertical force F2, the domain controller will no longer generate a control signal after making a logical judgment on the force signal, and the window glass will not move up or down.

[0053] The window lift motor receives a signal from the domain controller, and the motor rotates forward or reverse at a certain speed, thereby driving the glass to rise and fall.

[0054] When setting the calibration intervals for the lateral force F1 and the vertical force F2, it is necessary to reasonably determine the range of forces that the sensor can identify and respond to. As an example, the considerations for setting the calibration intervals usually include:

[0055] 1. User operating habits: Set the force calibration range according to the usage habits of most users to ensure that the system can adapt to the operating force of most users.

[0056] 2. Window materials and structures: The window materials and structures of different models may be different, which will affect the perception and transmission of applied force, and the calibration range needs to be set according to the specific situation.

[0057] 3. Sensor sensitivity: The sensitivity of the sensor determines the minimum detectable force value. The calibration interval should ensure that the sensor can accurately detect the force within its sensitivity range.

[0058] 4. Safety considerations: To avoid accidental lifting or lowering of the window due to misoperation or too light a touch, the calibration range should exclude excessively small force values.

[0059] 5. Environmental factors: Environmental factors such as temperature and humidity may affect the performance of the sensor, and these factors should be taken into account when setting the calibration interval.

[0060] For example:

[0061] 1. Calibration range of lateral force F1:

[0062] The minimum detectable value of the lateral force is set at 2 Newtons (N) to exclude light touches.

[0063] The maximum detectable value is set to 10 Newtons to prevent the user from having to use excessive force to operate the window.

[0064] 2. Calibration range of vertical force F2:

[0065] When the user swipes upward on the car window glass, the minimum detectable value of the vertical force is set to 1 Newton to ensure that the rising action can be triggered by a light touch.

[0066] The maximum detectable value is set to 8 Newtons to prevent users from using excessive force.

[0067] 3. Directionality of force:

[0068] The direction of the lateral force F1 is set from inside the vehicle to outside the vehicle to ensure that only the operation of the user inside the vehicle can trigger the window to be raised or lowered.

[0069] In the embodiment of the present invention, the lifting height of the window glass can be controlled by the duration of the force applied by the user to the window glass. This control method is different from the traditional method of controlling the height by sliding distance, and provides a new user interaction method. The following is a detailed description.

[0070] The force applied by the user to the vehicle window glass is detected by the pressure sensor assembly, and a timer is started to record the force application time.

[0071] Then, according to the preset time-height mapping relationship table, the force action time is converted into the corresponding window glass lifting height H. For example, the longer the force action time, the higher the window glass lifting height. The time-height mapping relationship table can be realized by calibrating the average force application time of the user and the expected window glass lifting height, for example: 0.5 seconds corresponds to the window glass rising or falling 2 cm, 1 second corresponds to the window glass rising or falling 5 cm, 2 seconds corresponds to the window glass rising or falling 10 cm, and 3 seconds corresponds to the window glass rising to the maximum height set by the user or falling to the minimum height set by the user.

[0072] The control signal is generated by taking the window glass lifting height as one of the control parameters.

[0073] The angle sensor located in the window lift motor is used to detect the rotation angle θ of the motor. The relationship between the rotation angle θ and the window glass lifting height H is as follows:

[0074]

[0075] Where R is the radius of the glass lifter rope pulley.

[0076] Therefore, according to the window glass lifting height H in the control signal, the rotation angle θ of the motor can be obtained, so as to control the motor to rotate a corresponding angle to lift the window glass to a height corresponding to the user force action time.

[0077] Furthermore, the embodiment of the present invention combines the glass lifting height H with the calibrated stroke L of the window glass from fully open to fully closed to obtain the window glass opening K, and displays it in real time at the window switch button position, so that the user does not need to look back to observe the lifting height of the front and rear window glasses when adjusting the window, but can intuitively adjust the window opening through the displayed real-time window glass opening, thereby enhancing the human-machine intelligent interaction experience between people and window control.

[0078] The calculation method of the window glass opening K is as follows:

[0079]

[0080] When the user's hand leaves the glass, the signal from the pressure sensor assembly is interrupted, and the domain controller terminates the control signal to the glass lifter motor through logical judgment, causing the motor to stop running and the glass to stop lifting and lowering.

[0081] Corresponding to the vehicle window lifting control method described in the first embodiment of the present invention, the second embodiment of the present invention further provides a vehicle window lifting control device, including:

[0082] A detection module is used to detect the force and direction applied by the user to the window glass and obtain the current opening status of the window;

[0083] The control module is used to generate a control signal according to the detected force and direction and the current opening status of the window, and control the window lifter motor to rotate forward or reverse according to the control signal, thereby driving the window glass to rise and fall.

[0084] Corresponding to the vehicle window lifting control method described in the first embodiment of the present invention, the third embodiment of the present invention further provides a vehicle window lifting control device, including:

[0085] one or more processors;

[0086] Memory;

[0087] One or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the one or more processors, and the one or more applications are configured to execute the vehicle window lifting and lowering control method.

[0088] Corresponding to the window lifting control method described in the aforementioned embodiment 1 of the present invention, the embodiment 4 of the present invention further provides a computer program product, including computer instructions, and the computer instructions instruct a computer device to execute operations corresponding to the method.

[0089] Preferably, the processor may be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor, or the processor may be any conventional processor. The processor is the control center of the device, and various parts of the device are connected using various interfaces and lines.

[0090] The memory mainly includes a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function, etc., and the data storage area can store related data, etc. In addition, the memory can be a high-speed random access memory, or a non-volatile memory, such as a plug-in hard disk, a smart memory card (SmartMedia Card, SMC), a secure digital (Secure Digital, SD) card, and a flash card (Flash Card), etc., or the memory can also be other volatile solid-state storage devices.

[0091] It should be noted that the above-mentioned device may include but is not limited to a processor and a memory, which can be understood by those skilled in the art.

[0092] For the working principle and process of the above embodiment, please refer to the description of the above embodiment of the present invention, which will not be repeated here.

[0093] It can be seen from the above description that compared with the prior art, the beneficial effect of the present invention is that the present invention realizes the intelligent adjustment of the lifting speed and opening of the window glass by detecting the force direction, force size and time of the hand touching the glass. Compared with the existing scheme, the need for frequent operation and adjustment is significantly reduced, and the operation efficiency is improved. At the same time, the introduction of the window opening display function makes it possible for users to adjust the window without looking back to observe the opening of the front and rear window glasses when adjusting the window. They only need to observe the opening of the window in real time at a preset position such as the window switch button position, and make precise adjustments according to the real-time opening, further improving the convenience of use. In addition, the present invention not only improves the human-computer interaction experience, but also significantly improves the sensory quality, thereby enhancing the customer's satisfaction, realizing the intelligence and convenience of the window glass lifting control, and bringing users a more efficient, comfortable and satisfactory experience.

[0094] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
