Description

Technical Field

[0001] This invention belongs to the field of remote control vehicle window technology, specifically a vehicle window control method. Background Technology

[0002] Car window controls are typically achieved through physical switches or voice commands. However, physical switches are often difficult to control precisely, especially while driving, while voice control is less timely and also struggles to pinpoint exact locations. Therefore, a simple, direct, and accurate control method is highly anticipated. Summary of the Invention

[0003] To address the above problems, this invention provides a vehicle window control device and method, comprising multiple infrared switches and a window controller. The infrared switches are installed on the inner door panel below the window, with a fixed distance between them. The infrared switches are electrically connected to the window controller, and the light path of the infrared switches is perpendicular to the ground and upwards. This invention utilizes infrared switches installed at the junction of the window and the inner door panel. The infrared switches are arranged on the inner door panel below the window, one every 5cm, for a total of 6-7 switches, the number depending on the window size. When the user wants to close or open the window, they only need to move their hand along the inside of the window to the desired height, and the window will then move to that position. The operation is simple and precise, improving the user's sense of control and thus increasing satisfaction.

[0004] The technical solution of this invention is as follows: a method for controlling vehicle windows, comprising the following steps: The S1 window controller detects whether there are any obstructions in the direction of the infrared switch's output light path. If there is no obstruction, repeat step S1; if there is an obstruction, continue to step S3. If the infrared switch of S3 is blocked by an object and the value exceeds the first threshold, the window controller enters the pre-control state. S4 determines the distance relationship between the obstruction and the infrared switch: If it is close to the infrared switch, the control direction is downward; If the infrared switch is far away, the control direction is upward.

[0005] The infrared switches are installed on the inner door panel below the windows. The infrared switches are distributed at a fixed distance from each other. The infrared switches are electrically connected to the window controller. The direction of the light emitted by the infrared switches is perpendicular to the ground and upward.

[0006] Furthermore, the fixed distance is 4cm.

[0007] Furthermore, the fixed distance is 5cm.

[0008] Furthermore, the fixed distance is 6cm.

[0009] Furthermore, the number of infrared switches is calculated as the window size divided by a fixed distance, rounded down to the nearest integer.

[0010] Furthermore, in step S4, the distance L of descent or ascent is determined by the formula... L = (L1 + ... + L) n ) / n Calculate, where n is the number of infrared switches that detected obstructions, and L n The distance between the infrared switch and the obstruction.

[0011] Furthermore, in step S3, the first threshold is 2.

[0012] Furthermore, in step S3, the first threshold is 1 / 3 of the number of infrared switches.

[0013] The beneficial effects of this invention are as follows: This invention utilizes infrared switches installed at the junction of the window and the inner door panel. These switches are spaced 5cm apart on the inner door panel below the window, totaling 6-7 switches, the number depending on the window size. To close or open the window, the user simply moves their hand along the inside of the window to the desired height, and the window moves to that position. The operation is simple and precise, enhancing the user's sense of control and thus improving satisfaction. Attached Figure Description

[0015] It should be noted that in the description of this invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0016] In this invention, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; a connection can be a mechanical connection or an electrical connection; a link can be a direct connection or an indirect connection through an intermediate medium, and can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0017] A vehicle window control device includes: multiple infrared switches and a window controller. The infrared switches are installed on the inner door panel below the window and are distributed at a fixed distance from each other. The infrared switches are electrically connected to the window controller, and the light path of the infrared switches is perpendicular to the ground and upward.

[0018] Furthermore, the fixed distance is 5cm.

[0019] A method for controlling vehicle windows includes the following steps: The S1 window controller detects whether there are any obstructions in the direction of the infrared switch's output light path. If there is no obstruction, repeat step S1; if there is an obstruction, continue to step S3. If the infrared switch of S3 is blocked by an object and the value exceeds the first threshold, the window controller enters the pre-control state. S4 determines the distance relationship between the obstruction and the infrared switch: If it is close to the infrared switch, the control direction is downward; If the infrared switch is far away, the control direction is upward.

[0020] Furthermore, in step S4, the distance L of descent or ascent is determined by the formula... L = (L1 + ... + L) n ) / n Calculate, where n is the number of infrared switches that detected obstructions, and L n The distance between the infrared switch and the obstruction.

[0021] Furthermore, in step S3, the first threshold is 2.

[0022] Human hand operation The user needs to place their hand along the car window and move it to the desired control position. The movement distance should be greater than 1cm. Moving it upwards represents a request to raise the window, and moving it downwards represents a request to lower the window. The stopping position is where the user wants the window to stay.

[0023] Infrared detection algorithm The infrared beams are counted as 6. Each infrared beam will emit a corresponding signal when it detects a hand, denoted as R1, R2, R3, R4, R5, and R6. When a hand is detected, the corresponding signal is set to 1. That is, when infrared switches numbered 2 and 3 detect a hand, R2=1 and R3=1.

[0024] When the window controller receives two or more valid infrared switches, it considers the window control to be effective and the window controller enters the pre-control state.

[0025] Control of window controller The distances detected by the infrared detection switch are denoted as P1, P2, P3, P4, P5, and P6, respectively. The target control position P of the window is the average of the detected distances. For example, if the window controller receives P2 and P3, and the values ​​of P2 and P3 gradually increase, then the target control position P = (P2 + P3) / 2, and the control direction is to raise the window. If the values ​​of P4 and P5 gradually decrease, then the target control position P = (P4 + P5) / 2, and the control direction is to lower the window. The position P corresponds to the window travel distance through calibration.
