Description

TECHNICAL AREA

The present invention relates to the field of vehicles, in particular to a method for adjusting the translucency of a vehicle window pane, an associated device and a vehicle.

STATE OF THE ART

At present, some high quality vehicles have an electronic curtain whose color can be adjusted by the user through a switch or knob (colorless or colored in a solid color), thus changing the translucency of the electronic curtain. However, such a method allows only a switching between a colorless state and a solid color, without being able to realize a stepless adjustment between a completely transparent state and a completely nontransparent state.

DETAILED DESCRIPTION

Hereinafter, specific embodiments of the present invention will be explained in more detail with reference to accompanying drawings. It should be understood that the specific embodiments described are merely for the purpose of describing and explaining the invention without restricting the invention.

1 shows a method for adjusting the light transmittance of a vehicle window pane according to an exemplary embodiment in a flowchart. As it turned out 1 results, the method may include the following steps.

In step 101 Receive a swipe command generated by the user via a vehicle window pane with adjustable translucency from the user.

In the present invention, the light transmittance of the vehicle window glass is adjustable. In one embodiment, the vehicle window pane may consist of two panes 1 . 2 exist that are on top of each other as out 2 it can be seen on the opposite sides of the two discs 1 . 2 a plurality of electrodes made of a transparent material 3 . 4 are provided and the electrodes 3 . 4 assigned location between the two discs 1 . 2 with several pieces of liquid crystal material 5 is filled, each piece of the liquid crystal material is associated with each pair of electrodes. By applying a control voltage with different frequency at both ends of individual transparent electrode pair, the hue of the respective liquid crystal material 5 radiated light to be controlled so as to realize an adjustable light transmittance of the vehicle window glass. At a higher frequency at the two ends of the transparent electrodes 3 . 4 applied control voltage has that of the liquid crystal material 5 emitted light of a lighter color, so that the vehicle window glass has a higher light transmittance, whereas, at a lower frequency at the two ends of the transparent electrodes 3 . 4 applied control voltage that of the liquid crystal material 5 radiated light has a darker color, so that the vehicle window glass has a lower light transmittance.

In another embodiment, the vehicle window pane with adjustable light transmission may itself be a touch screen. Thus, adjustment of the light transmittance of the vehicle window glass can be made by adjusting the displayed color of the touch screen.

In addition, the method may be used in a vehicle control device, wherein a sensor may be provided on the vehicle window pane to detect a swipe executed by the user via the vehicle window pane, with a swipe detected by the sensor being detected by the user via the vehicle window pane A swipe command is generated in response to the swipe operation performed by the user via the vehicle window glass, which is transmitted to the vehicle control device receiving the swipe command.

In step 102 Determining a target area to be set on the vehicle window pane and the target light transmittance associated with the target area to be set in response to the swipe command.

In the present invention, the target area to be set refers to an area on the vehicle window glass, the translucency of which the user can change, the user controlling both the light transmittance of a portion on the vehicle window glass and the vehicle window Translucency of the whole area on the vehicle window glass can change. The target area to be set can be determined in various ways. In one embodiment, the vehicle controller may determine the target area to be set by the following steps 3 can be seen.

In step 3021 Determining the start position of the stroking, the stop position of the stroking and the stroking direction in response to the swipe command.

In step 3022 Determining the target area to be set depending on the start position of the stroke, the stop position of the stroke, and the stroke direction.

In the present invention, the start position of the stroking refers to a position from which the swipe starts with a user's finger via the vehicle window glass, and the stop position of the swipe to a position where the swipe with a finger of the user User is finished via the vehicle window glass. When sweeping a user's finger across the vehicle window glass, the vehicle controller receives a swipe command generated by the swipe and determines the corresponding start position of the swipe, the stop position of swipe, and the swipe direction, followed by the swipe one of Starting position of the sweeping reference line is covered in a shift of the reference line along the strike direction up to the stop position of the stroking over the vehicle window, is determined as a target area to be set.

As it turned out 4A and 4B results in, for example, with the arrow 41 shown stroking the finger of the user on the vehicle window pane the corresponding start position 42 of the stroke, the stop position 43 of the stroke and the strike direction as vertical upward (see 4A) or obliquely at an angle of 45 ° relative to the horizontal direction (see 4B) be determined so that the area 45 passing through the start position 42 of the brushing reference line 44 as a reference line with a shift of the reference line 44 along the strike direction up to the stop position 43 is covered by the sweeping over the vehicle window, represents the target area to be set.

It should also be noted that the strike direction is any direction and the line shape of the reference line 44 may be a straight line, a curve, etc., with no specific limitation in the present invention.

How out 5 can be seen, the vehicle control device in another embodiment by the following steps determine the target area to be set.

In step 5021 Determining the number of touch points, the start position of the stroking, the stop position of the stroking and the stroking direction in response to the swipe command.

In step 5022 : Determine if the number of touch points is a first number. Perform the step 5023 if this is the case, and execute the step 5026 if this is not the case.

In step 5023 : Determine if there is an area with a current transmittance of less than 100% on the vehicle window glass. Perform the step 5024 if this is the case, and execute the step 5025 if this is not the case.

In step 5024 : Determine the area with a current transmittance of less than 100% as the target area to be set.

In step 5025 : Determining the entire area on the vehicle window pane as the target area to be set.

In step 5026 : Determine if the number of touch points is a second number. Perform the step 5027 , If this is the case.

In step 5027 Determining the target area to be set depending on the start position of the stroke, the stop position of the stroke, and the stroke direction.

In the present invention, the touch point when swiping with a finger is generated by the user through the vehicle window glass, and the number of touch points corresponds to the number of fingers on the vehicle window glass. If the number of touch points is the first number and an area having an actual transmittance of less than 100% (where the transmittance of the vehicle window glass is in the range of 0% to 100%) is present on the vehicle window glass, this indicates that that now there is an area of changed color, the area with a current transmittance of less than 100% being determined as a target area to be set. If the number of touch points is the first number and there is no area with an actual light transmission of less than 100% on the vehicle window glass, this indicates that that now the color of the entire vehicle window pane has not changed, wherein the entire area on the vehicle window pane can be determined as the target area to be set. If the number of touch points is the second number, the target area to be set is determined depending on the start position of the stroke, the stop position of the stroke and the stroke direction. A concrete embodiment concerning the determination of the target area to be set depending on the start position of the brushing, the stop position of the brushing and the brushing direction has been set in the above step 3022 explained in detail and here is waived a repetition.

In addition, it should be noted that the second number differs from the first number, the first number, for example, at 1 and the second number at 2 lies. In addition, the first number and the second number may be both a value set by the user and an empirical default value, with no specific limitation in the present invention.

In addition, the brushing at a number of touch points other than the first number and the second number may be considered invalid, in which case no adjustment of the translucency of the vehicle window glass occurs.

After determining the target area to be set, the vehicle control device determines a target light transmittance associated with the target area to be set. The target light transmittance is in a range of 0% to 100%. In this case, has a target light transmittance of 0% to a completely non-translucent state of the vehicle window glass and a target light transmittance of 100% in a completely translucent state of the vehicle window glass.

Similarly, the determination of the target transmittance can also be done in different ways. In one embodiment, the vehicle controller may determine the stop position of the sweep in response to the sweep command and determine a light transmittance of the vehicle window glass associated with the stop position of the sweep as the target light transmittance. The corresponding relationship between the stop position of the stroking and the light transmittance of the vehicle window glass can be predetermined so that when a finger is stroked by the user through the vehicle window, the vehicle controller receives a swipe command generated by the swipe, the corresponding stop position of the vehicle Then, based on the predetermined correspondence between the stop position of the coating and the light transmittance of the vehicle window glass, a light transmittance of the vehicle window pane associated with the stop position of the stroking is detected and the transmittance of the vehicle window glass is determined as a target transmittance.

In addition, it should be noted that the corresponding relationship between the stop position of the stroke and the light transmittance of the vehicle window pane is set both by the user and by default, with no specific limitation in the present invention.

In another embodiment, the vehicle control device may determine the strike direction depending on the swipe command and determine the target light transmittance depending on the strike direction. Specifically, in a first direction as the strike direction, the target light transmittance can be determined from the following equation (1): $$T_m=\text{Max}\left(T_D-\Delta T_1\mathrm{,\; 0}\%\right)$$

It stands T _m for the target translucency, T _D for the current light transmission of the target area to be set and ΔT ₁ for a predetermined first light transmittance change.

When the strike direction is a second direction opposite to the first direction, the target light transmittance can be determined from the following equation (2). $$T_m=\text{min}\left(T_D+\Delta T_{1}100\%\right)$$

For example, the first direction is vertically downward and the second direction is vertically upward. If the user wants to reduce the translucency of the vehicle window glass, he can run a finger vertically down the vehicle window pane, so that the A vehicle control device, upon receiving a swipe command generated by the vertical swipe operation from the swipe command, determines that the swipe direction is vertically downward, and thus, the swipe direction is the first direction, in which case the target translucency is based on the swipe direction The above equation (1) can be determined while the user can swipe vertically upward with a finger over the vehicle window glass if he wants to increase the light transmittance of the vehicle window pane, so that the vehicle control device upon receiving a swipe command generated by the vertical swipe operation judges from the swipe command that the strike direction is vertically upward, and thus the strike direction is the second direction, in which case the target light transmittance can be determined from the above equation (2).

Further, for example, the first direction extends horizontally to the right and the second direction horizontally to the left. If the user desires to reduce the translucency of the vehicle window glass, he may sweep a finger horizontally to the right across the vehicle window so that the vehicle controller, upon receiving a swipe command generated by the horizontal swipe to the right, determines from the swipe command that the swipe direction horizontally to the right, and thus the strike direction is the first direction, in which case the target translucency can be determined from equation (1) above, while the user can sweep horizontally to the left across the vehicle window with a finger, if he wants to increase the light transmittance of the vehicle window glass, so that the vehicle controller, upon receiving a swipe command generated by the horizontal swipe operation to the left, determines from the swipe command that the swipe direction is horizontal to the left, and thus the strike direction is the second direction, in which case the target light transmittance can be determined from equation (2) above.

In the above embodiments, it is provided that the light transmittance of the vehicle window is increased or decreased accordingly by a predetermined first Lichtdurchlässigkeitsänderung with each coating. Thus, the brushing direction is directly related to the increase or decrease of the translucency of the vehicle window glass, thereby facilitating the adjustment of the translucency of the vehicle window glass by the user according to his own needs to a desired light transmittance.

In addition, the first direction may be in any direction, and there is no specific limitation in the present invention. In addition, it should be noted that the first light transmittance change may be both a value set by the user and a default value, with no specific limitation in the present invention.

In a further embodiment, it is provided that the vehicle control device can determine the strike removal and strike direction as a function of the strike command and the target light transparency as a function of the strike removal and strike direction. Specifically, in a first direction as the strike direction, the target light transmittance can be determined from the following equation (3): $$T_m=\text{Max}\left(T_D-\mathrm{<figure-callout\; id="2"\; label="\Delta \; T"\; filenames="DE102017125872A1\_0007.png"\; state="\{\{state\}\}">\Delta \; </figure-callout>}{T}_{}{}_2\mathrm{,\; 0}\%\right)$$

It stands ΔT ₂ for a second light transmittance change associated with the strike removal.

When the strike direction is a second direction opposite to the first direction, the target light transmittance can be determined from the following equation (4). $$T_m=\text{min}\left(T_D+\mathrm{<figure-callout\; id="2"\; label="\Delta \; T"\; filenames="DE102017125872A1\_0007.png"\; state="\{\{state\}\}">\Delta \; </figure-callout>}{T}_{}{}_{2}100\%\right)$$

In the present invention, the correspondence relationship between the coating removal and the second light transmission change may be predetermined. In addition, the correspondence relationship can be set both by the user and by default, with no specific limitation in the present invention.

For example, the first direction is vertically downward and the second direction is vertically upward. If the user desires to reduce the translucency of the vehicle window glass, he / she can sweep vertically downward with a finger over the vehicle window pane by a distance, so that the vehicle controller, upon receiving a swipe command generated by the vertical swipe operation, determines from the swipe command, that the brushing direction is vertically downwards, and thus the brushing direction is the first direction, at the same time the brushing distance of the finger is determined by the user in the first direction and the second light transmission change associated with the brushing distance, and now the target light transmission is determined from the The above equation (3) can be determined while the user can sweep vertically upward with a finger over the vehicle window glass by a distance, if he wants to increase the light transmittance of the vehicle window, so that s the vehicle controller, upon receiving a swipe command generated by the vertical swipe operation, determines from the swipe command that the swipe direction vertically upward, and thus the strike direction is the second direction, simultaneously determining the strike distance of the finger from the user in the second direction and the second light transmittance change associated with the strike removal, and now the target light transmittance from the above equation (FIG. 4) can be determined.

Further, for example, the first direction is horizontally to the right and the second direction horizontally to the left. If the user desires to reduce the translucency of the vehicle window glass, he / she may sweep a finger horizontally to the right across the vehicle window by a distance so that the vehicle controller, upon receiving a swipe command to the right generated by the horizontal swipe, determines from the swipe command, that the brushing direction is horizontal to the right, and thus the brushing direction is the first direction, simultaneously determining the brush stroke distance from the user in the first direction and the second light transmission variation associated with the brush stroke, and now the target light transmission from the The above equation (3) can be determined while the user can sweep a finger horizontally to the left across the vehicle window glass by a distance if he wants to increase the light transmittance of the vehicle window glass That is, after receiving a swipe command generated by the horizontal swipe to the left from the swipe command, the vehicle controller determines that the swipe direction is horizontal to the left, and thus the swipe direction is the second direction, and at the same time the swipe distance of the finger can be determined by the user in the second direction and the second light transmission change associated with the stroke distance, and now the target light transmittance can be determined from the above equation (4).

In the above embodiments, it is provided that with each brushing, the light transmittance of the vehicle window pane is correspondingly increased or decreased by a second translucency change, the size of which depends on the brushing distance. In this case, the value size of the second change in light transmission is directly proportional to the coating removal, so that a larger coating removal provides for a higher value of the second change in light transmission. The immediate relationship between the coating distance and the amount of adjustment by which the light transmittance of the vehicle window glass is increased or decreased facilitates the adjustment of the transmittance of the vehicle window glass from the user to a desired light transmittance.

In yet another embodiment, it is provided that at T _D = 100%, ie in a completely translucent state of the vehicle window pane, the target light transmittance can be determined from equation (5) below: $$T_m=T_D-\mathrm{<figure-callout\; id="3"\; label="\Delta \; T"\; filenames="DE102017125872A1\_0007.png"\; state="\{\{state\}\}">\Delta \; </figure-callout>}{T}_{}{}_3$$

It stands ΔT ₃ for a predetermined third transmittance change.

At T _D = 0%, that is, in a completely non-translucent state of the vehicle window glass, the target light transmittance can be determined from the following equation (6): $$T_m=T_D-\mathrm{<figure-callout\; id="4"\; label="\Delta \; T"\; filenames="DE102017125872A1\_0007.png"\; state="\{\{state\}\}">\Delta \; </figure-callout>}{T}_{}{}_4$$

It stands ΔT ₄ for a predetermined fourth transmittance change.

When 0% <T _D <100%, the target light transmittance can be determined from the above equation (1), (2) or from the above equation (3), (4). This contributes to a diverse form of control of the translucency of the vehicle window glass and continues to provide an improved user experience.

Accordingly, in the above embodiments, the target transmittance of the vehicle window glass is reduced by a third transmittance change every time the vehicle window glass is in a completely transparent state, while the target transmittance of the vehicle window glass is increased by a fourth transmittance change each time it is swiped, when the vehicle window pane is in a completely non-translucent state.

In addition, it should be noted that the third transmittance change and the fourth transmittance change may be both a value set by the user and a default value, and the two values may be the same or different, and in the present invention there is no specific restriction.

In step 103 : Adjust the light transmittance of the target area to be set to the target transmittance, as shown 1 can be seen.

At an in 2 In the structure of the vehicle window glass shown in FIG. 2, after determining a target area to be set and the target light transmittance assigned to the target area to be adjusted, the vehicle control unit assigns the frequency of the control voltage at each end of the transparent electrode to the target area to be set in accordance with the received swipe command Determine the dependence of the target light transmittance and apply a control voltage with this frequency to both ends of the corresponding transparent electrode, so that a color change (brightened or darkened) of the light emitted from the corresponding liquid crystal material light can be controlled to the light transmittance of the target area to be set on the target Adjust light transmission.

In addition, by setting the displayed color of the target area to be set, the task of adjusting the light transmittance of the area to the target transmittance can be accomplished if the vehicle window glass itself is a touch screen.

The embodiments according to the embodiments of the present invention may include the following advantageous effects: determining a target area to be set on the vehicle window pane and target light transmittance associated with the target area to be set in response to a swipe command generated by the user via a vehicle window pane with adjustable light transmission; Adjust the translucency of the target area to be set to the target transmittance. Thus, the user can set the light transmittance of a vehicle window glass to any desired value with ease of operation. In addition, a change in the light transmittance of a portion of the vehicle window glass can be made possible, thus meeting individual user needs and improving the user experience.

In step 104 : Capture the user's fingerprint information upon detection of the user's wipe.

In step 105 : Determine whether the user is legitimate based on the user's fingerprint information. Perform the step 103 , If this is the case.

In the present invention, the user's fingerprint information may be captured via a fingerprint sensor and sent to the vehicle controller, which receives the user's fingerprint information and then compares the user's received fingerprint information with the legitimate user's pre-stored fingerprint information. If it corresponds to the prestored fingerprint information of the legitimate user, the user may be identified as the legitimate user, in which case the step 103 that is, setting the light transmittance of the target area to be set to the target transmittance while the user is detected as an unlawful user if it does not correspond to the pre-stored right user's fingerprint information, in which case it can be determined that the unauthorized User is not authorized to adjust the translucency of the vehicle window glass. Thus, the driving safety risk resulting from an undesirable change in the light inside the vehicle due to a sudden adjustment of the translucency of the vehicle window by an unlawful user, such as a child, can be precluded, thus ensuring the personal safety of the driver and passenger.

It should also be noted that the step 105 and 106 both before the step 101 as well as after the step 101 or after the step 102 can be carried out, wherein in the present invention, no specific limitation.
