Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
At present, with the rapid development of automobile technology, various functions on automobiles are more and more abundant, including window ventilation. When the vehicle activates the window ventilation function, the window can be controlled to move to a target position, so that the financial safety in the vehicle is ensured while the air circulation inside and outside the vehicle is realized.
However, in the actual control process, when the motor for controlling the window to move is powered off, the motor cannot stop rotating immediately due to inertia, and can continue to rotate for a short distance, so that the actual stop position of the window is deviated from the target position; the deviation can be influenced by superposition factors such as vehicle environment temperature, storage battery voltage change and aging of a vehicle window mechanism, so that the actual position of the ventilation opening of the vehicle window and the target position have different degrees of deviation, and risks such as poor ventilation effect of the vehicle window or property theft in the vehicle are generated.
However, in actual control, the actual stop position of the window is deviated from the target position due to various reasons such as window aging; the position of the ventilation opening of the vehicle window deviates from the target value, so that the ventilation effect of the vehicle window is poor or property in the vehicle is stolen and the like.

The following is introduced with respect to an application environment of the vehicle window control method provided by the embodiment of the present invention:
referring to fig. 1, fig. 1 is a schematic diagram illustrating an application environment suitable for use in embodiments of the present application. The vehicle 100 provided by the embodiment of the present application may include a controller 110 and at least one window 120.
In an embodiment of the present application, the controller 110 is coupled to at least one vehicle window 120. The controller 110 may be an ECU (Electronic Control Unit), also called a Vehicle On Board Computer (Vehicle On Board Computer) or a Vehicle Computer; the controller 110 may also be an MCU (micro controller Unit), which is also called a Single Chip microcomputer (Single Chip Microcontroller) or a Single Chip microcomputer. The controller 110 may control the operation of at least one vehicle window 120. The controller 110 is configured to receive a window control command and control operation of the window 120 according to the current window position and the target window position.
In some embodiments, as shown in fig. 2, the window 120 includes a position determining unit 121, a window moving unit 122, and a window body 123.
In an embodiment of the present application, the Position determining unit 121 may include a Position Sensor (Position Sensor), such as a Hall Sensor; the position determining unit 121 is connected to the window body 123, and the position determining unit 121 is configured to be connected to the controller 110, and send the position of the window body 123 to the controller 110 after determining the current position of the window body 123 and the moved position of the window body 123.
In some embodiments, the controller 110 may compare the current position of the window body 123 obtained by the position determining unit 121 with a target position, and determine a difference between the current position of the window body 123 and the target position as a difference parameter if the difference is greater than a first preset threshold.
In some embodiments, the controller 110 further compares the moved position of the window body 123 acquired by the position determining unit 121 with a target position, and determines that the difference between the adjusted position of the window body 123 and the target position is a target difference if the difference is greater than a second preset threshold.
In an embodiment of the present application, the window moving unit 122 may be a power Glass Lifter (Electric Glass Lifter), including but not limited to a Rope-driven power Glass Lifter (Rope-driven Electric Glass Lifter); the electric glass lifter comprises a Motor, such as a Brushless direct current Motor (brush Motor); the window moving unit 122 is connected to the window body 123, and the window moving unit 122 is configured to be connected to the controller 110 and control the movement of the window body 123.
In some embodiments, after receiving the window control command, the controller 110 determines a position control parameter according to the difference parameter and a preset compensation parameter pre-stored in the controller, and adjusts the position of the window body 123 through the window moving unit 122 according to the position control parameter.
In some embodiments, if the target difference obtained by the controller 110 is greater than the second preset threshold, the controller 110 updates the preset compensation parameter according to the obtained target difference, and controls the window 120 to move according to the updated preset compensation parameter and the target difference.
The specific process will be explained in detail in the following examples.
Referring to fig. 3, a vehicle window control method provided in an embodiment of the present application may be applied to the vehicle 100, where the embodiment describes a flow of steps of a vehicle side, and the method may include: step 210 to step 250.
And step 210, if the vehicle window control instruction is detected, determining a difference value parameter according to the current position of the vehicle window and the target position.
In some embodiments, the window control instruction may be sent by a user through an on-board computer of the vehicle 100, and the window instruction may also be generated by triggering when the window is not satisfied with the relevant conditions after the vehicle 100 initially controls the window to move, which is not limited in this application.
For example, the current position of the window may be represented as the relative distance between the upper edge of the window and the upper edge of the window frame; it will be appreciated that, with the minimum relative distance, the window is fully closed; when the relative distance is at a maximum, the window is fully open.
It will be appreciated that the current position of the window may also include other representations, for example, the height of the window may be used for representation; for example, when the height of the window is maximum, the window is fully closed; when the height of the car window is minimum, the car window is completely opened; this is not limited by the present application.
In some embodiments, the target position of the window may be represented as a position 2CM to 4CM from the upper edge of the window frame. Preferably, the target position of the window may be selected to be 3CM from the upper edge of the window frame. It can be understood that the farther the target position of the window is from the upper edge of the window frame, the better the ventilation effect of the window is; but too far away increases the risk of property theft; therefore, the target position of the car window can be set according to actual practical requirements, and the application does not limit the target position.
In some embodiments, the difference parameter includes a distance difference and an adjustment direction.
In an embodiment of the present application, the distance difference of the window may be expressed as a relative distance between the current position of the window and the target position of the window; it will be appreciated that the distance difference between the windows may also include other expressions, for example, it may be expressed by the Width of a PWM (Pulse Width Modulation) signal input to a motor controlling the window lift; this is not limited by the present application.
In an embodiment of the present application, the adjustment direction of the window includes a first direction and a second direction; it is understood that the first direction is opposite to the second direction.
Wherein the first direction is a direction when the vehicle 100 controls the window to ascend, and the second direction is a direction when the vehicle 100 controls the window to descend. Illustratively, the window gradually closes as it moves in a first direction; when the window moves in the second direction, the window is gradually opened.
According to different adjustment directions, the determination modes of the distance difference value are different; for example, if the top of the window frame is used as a zero point, and the bottom of the window frame is used as a coordinate axis direction to establish a coordinate system, when the adjustment direction is a first direction, the coordinate of the current position is subtracted by the coordinate of the target position to obtain a distance difference value; and when the adjusting direction is the second direction, subtracting the coordinate of the current position from the coordinate of the target position to obtain a distance difference value. It can be understood that, the coordinate system may be established with different positions as zero points to obtain the coordinates of the current position and the target position, which is not limited in the present application; meanwhile, the current position and the target position may also include other expression forms, such as a PWM signal width input to a motor controlling the window lift, and the like, which is not limited in the present application.
In the embodiment of the present application, the values of the preset compensation parameters used are stored in a storage medium disposed in the vehicle 100, such as an electronic memory like an EEPROM (electrically erasable programmable read only memory), an EPROM, a hard disk, or a ROM. Preferably, the storage medium for storing the preset compensation parameter may be a non-volatile computer-readable medium (non-volatile computer-readable storage medium); different storage media can be selected according to actual use requirements, and the application is not limited to this.
In some embodiments, the preset compensation parameters may be different when the window is in different adjustment directions.
In an embodiment of the present application, when the adjustment direction of the vehicle window is a first direction, the preset compensation parameter is a first compensation parameter; when the adjusting direction of the car window is the second direction, the preset compensation parameter is the second compensation parameter.
In some embodiments, the position control parameters determined from different preset compensation parameters and distance differences may also be different when the window is in different adjustment directions.
In the embodiment of the application, when the adjusting direction of the vehicle window is a first direction, the position control parameter is determined according to the difference between the distance difference value of the vehicle window and the first compensation parameter; specifically, the position control parameter is the distance difference of the window minus the first compensation parameter.
It will be appreciated that when the adjustment direction of the window is the first direction, the window is in a raised adjustment state. After the motor for controlling the window to move is powered off, the motor cannot stop rotating immediately but rotates a short distance under the influence of the self-motion inertia of the motor. The adjustment direction of the window is upward, if the motor is not powered off in advance at the moment, the window cannot stop at a preset target position, but a certain offset occurs upwards, so that the power-off position of the motor needs to be lower than the target position by a certain distance at the moment. At this time, the position control parameter needs to be determined according to the difference between the distance difference of the vehicle window and the first compensation parameter, so that the power-off position of the motor is lower than the target position by a certain distance.
In the embodiment of the application, when the adjusting direction of the vehicle window is a second direction, the position control parameter is determined according to the difference between the distance difference value of the vehicle window and the second compensation parameter; specifically, the position control parameter is the distance difference of the window minus the second compensation parameter.
It will be appreciated that when the adjustment direction of the window is the second direction, the window is in a lowered adjustment state. After the motor for controlling the window to move is powered off, the motor cannot stop rotating immediately but rotates a short distance under the influence of the self-motion inertia of the motor. The window is adjusted downwards, if the motor is not powered off in advance at the moment, the window cannot stop at a preset target position, but is deviated downwards to a certain extent, so that the power-off position of the motor needs to be higher than the target position by a certain distance at the moment. At this time, the position control parameter needs to be determined according to the difference between the distance difference of the vehicle window and the first compensation parameter, so that the power-off position of the motor is higher than the target position by a certain distance.
In some embodiments, if the distance difference of the vehicle window is greater than a first preset threshold, the position control parameter is determined according to the distance difference, the adjustment direction and a preset compensation parameter.
It will be appreciated that when the distance difference between the windows is less than or equal to the first predetermined threshold, the windows have been adjusted to the appropriate position to meet the user's needs and the windows are no longer repositioned.
In an embodiment of the present application, the first preset threshold may range from 4MM to 6MM. Preferably, the first preset threshold may be selected to be 5MM. It can be understood that the smaller the first preset threshold is, the higher the precision of the window position adjustment is; the first preset threshold value can be set according to actual use precision requirements and specific conditions of the car window, and the method is not limited by the application.
And step 230, adjusting the position of the vehicle window according to the position control parameter.
In some embodiments, after determining the position control parameter, the vehicle 100 may convert the position control parameter into a corresponding PWM signal and send the PWM signal to a motor for controlling the window position, thereby adjusting the window position. It is understood that the vehicle 100 may also adopt other ways of adjusting the position of the window, and the adjustment way is different according to the type number of the vehicle or the window, etc., and the present application does not limit this.
And 240, determining a target difference value according to the adjusted position of the car window and the target position.
In some embodiments, the adjusted position of the window may be the relative distance between the upper edge of the window and the upper edge of the window frame after the position is adjusted in step 230; it is to be understood that the adjusted position of the window may also include other expressions to indicate a relative distance between the upper edge of the window and the upper edge of the window frame, which is not limited in the present application.
In some embodiments, the target difference may be expressed as a relative distance of the adjusted position of the window from a target position of the window; it will be appreciated that the target difference also includes other types of representations, such as may be represented by the width of a PWM signal input to a motor controlling window lift; this is not limited by the present application.
According to different adjusting directions, the determining mode of the target difference value is different; for example, if the top of the window frame is taken as a zero point, the bottom of the window frame is taken as a coordinate axis direction to establish a coordinate system, and when the adjusting direction is a first direction, the coordinate of the adjusted position is subtracted by the coordinate of the target position to obtain a target difference value; and when the adjusting direction is the second direction, subtracting the coordinate of the current position from the coordinate of the adjusted position to obtain a target difference value. It can be understood that, the coordinate system may be established with different positions as zero points to obtain coordinates of the adjusted position and the target position, which is not limited in the present application; meanwhile, the adjusted position and the target position may also include other expression forms, such as a PWM signal width input to a motor controlling the lifting of the window, and the like, which is not limited in the present application.
And step 250, updating the preset compensation parameter according to the target difference value.
It can be understood that, through the updating of the compensation parameters, the vehicle can obtain the preset compensation parameters suitable for the current condition when the vehicle is under different environmental conditions such as temperature, humidity and the like and the self mechanism components are not in ideal conditions (such as low battery voltage and aging of the window control device), so that the window is accurately controlled to move to the target position.
In some embodiments, if the target difference is greater than a second preset threshold, determining a target compensation value according to the value of the preset compensation parameter and the target difference; and updating the value of the preset compensation parameter to the target compensation value.
It will be appreciated that when the target difference value of the window is less than or equal to the second preset threshold value, the window has been adjusted to a suitable position to meet the user's needs, and the value of the preset compensation parameter is not updated.
In an embodiment of the present application, the second preset threshold may range from 4MM to 6MM. Preferably, the second preset threshold may be selected to be 5MM. It can be understood that the smaller the second preset threshold is, the higher the precision of the window position adjustment is; the second preset threshold value can be set according to actual use precision requirements and specific conditions of the car window, and the method is not limited by the application.
In some embodiments, the step 250 of updating the preset compensation parameter according to the target difference comprises the following steps.
(1) And determining a middle compensation value according to the preset proportional coefficient and the target difference value.
In an embodiment of the present application, the preset scaling factor may range from 0.35 to 0.65. Preferably, the predetermined scaling factor may be selected to be 0.5. It is understood that the preset proportionality coefficient may be set according to specific conditions of the vehicle window, and the application is not limited thereto.
In the embodiment of the present application, the intermediate compensation value is the target difference multiplied by the preset scaling factor.
(2) And determining a target compensation value according to the sum of the value of the preset compensation parameter and the intermediate compensation value.
(3) And updating the value of the preset compensation parameter to be the target compensation value.
In an embodiment of the present application, the updated value of the preset compensation parameter may be stored in a storage medium disposed in the vehicle 100, such as an electronic memory like an EEPROM (electrically erasable programmable read only memory), an EPROM, a hard disk, or a ROM. Preferably, the storage medium for storing and updating the preset compensation parameter may be a non-volatile computer-readable storage medium; different storage media can be selected according to actual use requirements, and the application is not limited to this.
In some embodiments, as shown in fig. 4, after the step 250, updating the preset compensation parameter according to the target difference, the vehicle window control method provided by the embodiment of the present application further includes the following steps.
And step 260, if the target difference value is larger than a second preset threshold value, triggering to generate a vehicle window control instruction.
It can be understood that by judging the numerical relationship between the target difference value and the second preset threshold value, whether the current window is adjusted to the target position or not can be determined, so that whether the window position needs to be continuously adjusted or not can be determined; for example, if the target difference is greater than a second preset threshold value, and the vehicle window is not adjusted to the target position at this time, triggering to generate a vehicle window control instruction, and continuing to adjust the vehicle window position; if the target difference is smaller than a second preset threshold value, the vehicle window is adjusted to the target position at the moment, and the vehicle window position is not adjusted continuously.
In some embodiments, if the target difference is greater than a second preset threshold, generating a window control command is triggered.
It is understood that after triggering generation of the window control command, the vehicle 100 restarts the window control movement operation from step 210.
It can be understood that when the target difference value of the window is less than or equal to the second preset threshold value, the window has been adjusted to a suitable position meeting the user's needs, and no longer triggers the generation of the window control command.
In an embodiment of the present application, the second preset threshold may range from 4MM to 6MM. Preferably, the second preset threshold may be selected to be 5MM. It can be understood that the smaller the second preset threshold value is, the higher the precision of the window position adjustment is; the second preset threshold value can be set according to actual use precision requirements and specific conditions of the car window, and the method is not limited by the application.
