Detailed Implementation

[0018] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0019] It should be understood that the terms "comprising" and other similar expressions in the specification, claims, and accompanying drawings of this invention are intended to cover a non-exclusive inclusion, such as a process, method, system, or apparatus that includes a series of steps or units and is not limited to the listed steps or units. Furthermore, "first" and "second" are used to distinguish different objects and are not intended to describe a specific order.

[0020] According to the first aspect of this application, Figure 1 As shown, this embodiment provides a method for controlling the speed of automobile doors and windows, including the following steps: Step S1: Establish a mapping relationship between pressing parameters and output duty cycle, wherein the pressing parameters include pressing pressure and / or pressing time, the pressing pressure is the pressing pressure of the user pressing the switch button of the car door and window, and the pressing time is the pressing time of the user pressing the switch button of the car door and window.

[0021] In this way, by establishing a mapping relationship between pressing parameters and output duty cycle, different output duty cycles can be obtained when different pressing parameters are output, thereby controlling different moving speeds of car doors and windows.

[0022] In this embodiment, the moving speed of the car doors and windows includes the opening speed and closing speed of the car doors and windows. The car doors and windows include car doors and car windows. Car doors include driver's door, passenger door, two rear doors, trunk door, etc., and car windows include side windows, sunroof glass, etc. This embodiment does not limit these.

[0023] In this embodiment, when it is necessary to control the preset moving speed of the car door and window, a mapping relationship between the preset pressing parameters and the output duty cycle is established for the car door and window.

[0024] In this embodiment, the switch button includes, but is not limited to, physical buttons and virtual buttons, and the switch button integrates pressure sensing and time detection.

[0025] In this embodiment, the moving speed of the car doors and windows includes the opening speed and closing speed of the car doors and windows.

[0026] In this embodiment, the pressing parameters include pressing time, pressing pressure, and a combination of pressing time and pressing pressure.

[0027] In some embodiments of this example, when the pressing parameter includes pressing pressure, the mapping relationship between the pressing parameter and the output duty cycle is a first proportional relationship between the pressing pressure and the output duty cycle, that is, the greater the pressing pressure, the greater the output duty cycle, and the greater the moving speed of the car door and window.

[0028] Specifically, a first proportional relationship is established based on the first pressing coefficient, pressing pressure, first pressure threshold, and output duty cycle, and the calculation formula is as follows:

[0029] in, The first pressure coefficient, The first pressure threshold, The pressing pressure, To fix the minimum output duty cycle, To output the duty cycle.

[0030] In some embodiments of this example, when the pressing parameter includes pressing time, the mapping relationship between the pressing parameter and the output duty cycle is a second direct proportional relationship between the pressing time and the output duty cycle, that is, the longer the pressing time, the larger the output duty cycle, and the greater the moving speed of the car door and window.

[0031] Specifically, a second proportional relationship is established based on the second press coefficient, press time, first time threshold, and output duty cycle, and the calculation formula is as follows:

[0032] in, This is the second pressure coefficient. The first time threshold, This refers to the pressing time.

[0033] In some embodiments of this example, when the pressing parameters include pressing time and pressing pressure, the mapping relationship between the pressing parameters and the output duty cycle is a third proportional relationship between the pressing time, the pressing pressure, and the output duty cycle. That is, the larger the product of the pressing time and the pressing pressure, the larger the output duty cycle and the greater the moving speed of the car door and window.

[0034] Specifically, a third proportional relationship is established based on the third press coefficient, press pressure, first pressure threshold, press time, first time threshold, and output duty cycle. The calculation formula is as follows:

[0035] in, This is the third pressure coefficient.

[0036] In some implementations of this embodiment, such as Figure 2 As shown, when the pressing parameters include pressing pressure and pressing time; Set the first pressure threshold. Second pressure threshold First time threshold Second time threshold Second pressure threshold Greater than the first pressure threshold Second time threshold Greater than the first time threshold ; When pressing pressure Less than the second pressure threshold And pressing time Less than the first time threshold In the mapping relationship between the pressing parameters and the output duty cycle, the pressing parameters correspond to a fixed minimum output duty cycle. .

[0037] When pressing pressure Greater than or equal to the second pressure threshold And pressing time Less than the first time threshold If the output duty cycle Less than or equal to the fixed maximum output duty cycle The mapping relationship between the pressing parameter and the output duty cycle is a first direct proportional relationship between the pressing pressure and the output duty cycle. If the output duty cycle Greater than the fixed maximum output duty cycle The pressing parameter corresponds to a fixed maximum output duty cycle. .

[0038] When pressing pressure Less than the first pressure threshold And pressing time Greater than or equal to the first time threshold And less than the second time threshold The mapping relationship between the pressing parameters and the output duty cycle is a second direct proportional relationship between the pressing time and the output duty cycle. .

[0039] When pressing pressure Greater than or equal to the first pressure threshold And less than the second pressure threshold And pressing time Greater than or equal to the first time threshold And less than the second time threshold The mapping relationship between the pressing parameters and the output duty cycle is a third direct proportional relationship between the pressing time, the pressing pressure, and the output duty cycle. .

[0040] When pressing pressure Greater than or equal to the second pressure threshold And pressing time Greater than or equal to the first time threshold And less than the second time threshold If the output duty cycle Less than or equal to the fixed maximum output duty cycle The mapping relationship between the pressing parameters and the output duty cycle is a third direct proportional relationship between the pressing time, the pressing pressure, and the output duty cycle. If the output duty cycle Greater than the fixed maximum output duty cycle The pressing parameter corresponds to a fixed maximum output duty cycle. .

[0041] When pressing pressure For any value, the pressing time Greater than or equal to the second time threshold In the mapping relationship between the pressing parameters and the output duty cycle, the pressing parameters correspond to a fixed maximum output duty cycle. .

[0042] Step S2: Obtain the current pressing parameters of the user pressing the switch button of the car door window. The current pressing parameters include the current pressing pressure and / or the current pressing time. Input the current pressing parameters into the mapping relationship between pressing parameters and output duty cycle to obtain the current output duty cycle. Obtain the current moving speed based on the current output duty cycle.

[0043] In some embodiments of this example, the current moving speed is obtained based on the current output duty cycle. Specifically, the current moving speed is obtained based on the current output duty cycle, the motor back electromotive force constant, the power supply rated voltage, and the mechanical conversion coefficient. The calculation formula is as follows:

[0044] in, Let be the back electromotive force constant of the motor. This is the rated voltage of the power supply. For mechanical conversion coefficient, This represents the current movement speed.

[0045] In this embodiment, when the current pressing parameters include the current pressing pressure, the current pressing pressure is input into the first proportional relationship between pressing pressure and output duty cycle to obtain the current output duty cycle.

[0046] Given the current press parameters, including the current press time, the current press time is input into the second proportional relationship between the press time and the output duty cycle to obtain the current output duty cycle.

[0047] Given that the current pressing parameters include the current pressing pressure and the current pressing time, the mapping relationship between the pressing parameters and the output duty cycle is determined based on the current pressing pressure and the current pressing time, thereby obtaining the current output duty cycle.

[0048] Thus, this embodiment can adaptively adjust the movement time of car doors and windows based on the current pressing pressure and / or the current pressing time to cope with various car door and window opening and closing situations.

[0049] Step S3: Control the car doors and windows to open and close at the current moving speed.

[0050] In some embodiments of this example, if the car door or window is opened to a first preset opening threshold or closed to a second preset opening threshold, the car door or window opens and closes at a preset moving speed. The first preset opening threshold and the second preset opening threshold can be set as needed, and this example does not limit this.

[0051] In one specific embodiment, the first preset opening threshold is 85% of the opening stroke, and the second preset opening threshold is 10% of the closing stroke. If the car door or window is above 85% of the opening stroke when it is open and below 10% of the closing stroke when it is closed, then the car door or window opens and closes at a preset moving speed, which is the initial moving speed.

[0052] According to the second aspect of this application, such as Figure 3 As shown, this embodiment provides a car door and window speed control system, including: The model building module is used to establish the mapping relationship between pressing parameters and output duty cycle. The pressing parameters include pressing pressure and / or pressing time. The pressing pressure is the pressing pressure of the user pressing the switch button of the car door and window, and the pressing time is the pressing time of the user pressing the switch button of the car door and window. The acquisition module is used to acquire the current pressing parameters of the user pressing the switch button of the car door window. The current pressing parameters include the current pressing pressure and / or the current pressing time. The current pressing parameters are input into the mapping relationship between pressing parameters and output duty cycle to obtain the current output duty cycle. The current moving speed is obtained based on the current output duty cycle. The control module is used to control the opening and closing of the car doors and windows at the current moving speed.
