[0002] In order to improve the aesthetics of the vehicle and reduce the wind resistance and wind noise between the door glass and the window frame, the zero-step difference design between the door glass and the window frame is becoming more and more popular in automobiles.

BRIEF DESCRIPTION OF THE DRAWINGS

[0059] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings required for use in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings in the following description are some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0060] Figure 1 Flow chart of a zero-order difference vehicle window self-test method according to an embodiment of the present invention;

[0061] Figure 2 Schematic diagram of a zero-order difference vehicle window self-test device in an embodiment of the present invention. DETAILED DESCRIPTION

[0062] The embodiments of the present invention provide a zero-order difference vehicle window self-detection method and device, thereby filling the gap in the zero-order difference vehicle window glass and window frame flush detection technology.

[0063] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0064] like Figure 1 As shown, the zero-order difference vehicle window self-test method of this embodiment includes:

[0065] Step S1, controlling the zero-order difference window to perform a complete lifting process;

[0066] Step S2, when the zero-order difference vehicle window is in a closed state, obtaining a first gap and a surface difference between a glass edge and a window frame of the zero-order difference vehicle window;

[0067] Step S3, if the first gap and the face difference are lower than a first preset threshold, it is determined that the glass is flush with the window frame;

[0068] Step S4: if the first gap and the surface difference are higher than the first preset threshold, determine whether the glass is flush with the window frame.

[0069] In this embodiment, the gap and face difference between the glass edge and the window frame can also be obtained under the condition that the zero-order difference window is not in the lifting process to determine whether the glass is flush with the window frame. However, when using the vehicle, the user often controls the lifting of the zero-order difference window. The gap and face difference under static conditions cannot reflect the influence of the glass lifting action on the gap and face difference, which will make the self-test result unreliable. Step S1 controls the zero-order difference window to perform a complete lifting process, so that the first gap and face difference obtained in step S2 are the gap and face difference that take into account the influence of the glass lifting action. The first gap and face difference are more real, which can make the self-test result of the zero-order difference window more reliable.

[0070] In step S2, the first gap and face difference actually include the absolute value of the gap between the glass edge and the window frame and the absolute value of the face difference between the glass edge and the window frame, that is, the first gap and face difference are actually two values, and their judgment logic is the same, so the first gap and face difference are used instead in this embodiment. The first gap and face difference between the glass edge and the window frame at the B-pillar can be obtained, and the first gap and face difference at only one position at the B-pillar can be obtained, but the first gap and face difference at a single position are not representative. In order to improve the reliability of the zero-order difference window self-test result, the first gap and face difference at multiple positions at the B-pillar can be obtained, such as evenly selecting the upper, middle and lower positions at the B-pillar to obtain the first gap and face difference. At this time, step S3 is: if the first gaps and face differences at all positions are lower than the first preset threshold, it is determined that the glass is flush with the window frame; step S4 is: if the first gap and face difference at at least one position are higher than the first preset threshold, it is determined whether the glass is flush with the window frame.

[0071] It can be understood that, in step S3, if the first gap and the face difference are lower than the first preset threshold, it means that the first gap and the face difference between the glass edge of the zero-order difference window and the window frame are small, and it can be considered that the glass of the zero-order difference window is flush with the window frame, and the zero-order difference window has good aesthetics; in step S4, if the first gap and the face difference are higher than the first preset threshold, it is necessary to determine whether the glass is flush with the window frame.

[0072] As can be seen from the above, after controlling the zero-order difference window to perform a complete lifting process, this embodiment obtains the first gap and face difference between the glass edge and the window frame of the zero-order difference window. The first gap and face difference take into account the influence of the glass lifting and lowering action. The first gap and face difference are more realistic, which can make the self-inspection result of the zero-order difference window more reliable; if the first gap and face difference are lower than the first preset threshold, it means that the first gap and face difference are small, and it can be considered that the glass and window frame of the zero-order difference window are flush, and the zero-order difference window has good aesthetics; if the first gap and face difference are higher than the first preset threshold, it is determined whether the glass and window frame are flush; the lack of glass and window frame flush detection technology for zero-order difference windows is made up, and effective self-inspection of the aesthetics of zero-order difference windows is realized.

[0073] In step S4 of this embodiment, judging whether the glass is flush with the window frame may include: directly judging whether the glass is not flush with the window frame. This is equivalent to judging whether the glass is not flush with the window frame based on the first gap and surface difference obtained once, and the self-checking process is simple. However, since an experiment is accidental, in order to improve the reliability of the self-checking result, in this embodiment, preferably, judging whether the glass is flush with the window frame in step S4 includes:

[0074] Control the zero-order difference window to perform multiple complete lifting processes;

[0075] After each lifting process is completed and the zero-order difference window is in a closed state, a second gap and a surface difference between the glass edge and the window frame are obtained;

[0076] If the average value of the plurality of second gaps and flushnesses is lower than a first preset threshold, it is determined that the glass is flush with the window frame;

[0077] If the average value of the plurality of second gaps and flushnesses is higher than a first preset threshold, it is determined that the glass is not flush with the window frame.

[0078] This is equivalent to obtaining the second gap and flushness at one or more positions each time a lifting process is completed, and each position has multiple second gaps and flushnesses. If only multiple second gaps and flushnesses at a single position are obtained, if the average value of the multiple second gaps and flushnesses at this position is lower than the first preset threshold, it is determined that the glass is flush with the window frame; if the average value of the multiple second gaps and flushnesses at this position is higher than the first preset threshold, it is determined that the glass is not flush with the window frame. If the second gaps and flushnesses at multiple positions are obtained, if the average value of the multiple second gaps and flushnesses at each position is lower than the first preset threshold, it is determined that the glass is flush with the window frame; if the average value of the multiple second gaps and flushnesses at at least one position is higher than the first preset threshold, it is determined that the glass is not flush with the window frame.

[0079] In this embodiment, in addition to the self-inspection of the aesthetics of the zero-order difference window, it is also necessary to self-inspect the sealing of the zero-order difference window under the premise of good aesthetics. Therefore, after steps S3 and S4, the zero-order difference window self-inspection method further includes:

[0080] After determining that the glass is flush with the window frame, the zero-order difference window is controlled to perform a complete lifting process;

[0081] When the zero-order difference window is in a closed state, obtaining a first pressure exerted on a sealing strip of a vehicle door opening;

[0082] If the first pressure is higher than the second preset threshold, it is determined that the sealing performance of the zero-order difference window is qualified;

[0083] If the first pressure is lower than the second preset threshold, it is determined whether the sealing performance of the zero-order difference window is qualified.

[0084] The first pressure obtained here also takes into account the influence of the glass lifting action. The first pressure is more realistic and can make the zero-order difference window self-test result more reliable. The first pressure of a single position of the door opening sealing strip can be obtained, but the first pressure of a single position is not representative. In order to improve the reliability of the zero-order difference window self-test result, the first pressures of multiple positions can be obtained, such as the first pressures of the sealing strips at the four positions of the door opening, the top, bottom, left and right. At this time, if the first pressures of all positions are higher than the second preset threshold, it is determined that the sealing of the zero-order difference window is qualified; if the first pressure of at least one position is lower than the second preset threshold, it is determined whether the sealing of the zero-order difference window is qualified.

[0085] It is understandable that the better the sealing performance of the zero-order difference window, the greater the pressure on the door opening sealing strip should be. Therefore, if the first pressure is higher than the second preset threshold, it means that the pressure on the door opening sealing strip is very large and the sealing performance of the zero-order difference window is good.

[0086] Among them, judging whether the sealing of the zero-order difference window is qualified may include: judging that the sealing of the zero-order difference window is unqualified. This is equivalent to judging that the sealing of the zero-order difference window is unqualified based on only the first pressure obtained once, and the self-checking process is simple. However, since an experiment is accidental, in order to improve the reliability of the self-checking result, this embodiment may preferably: judging whether the sealing of the zero-order difference window is qualified, including:

[0087] Control the zero-order difference window to perform multiple complete lifting processes;

[0088] After each lifting process is completed and the zero-step difference window is in a closed state, obtaining a second pressure on the door opening sealing strip;

[0089] If the average value of the plurality of second pressures is higher than the second preset threshold, it is determined that the sealing performance of the zero-order difference window is qualified;

[0090] If the average value of the plurality of second pressures is lower than the second preset threshold, it is determined that the sealing performance of the zero-order difference window is unqualified.

[0091] This is equivalent to obtaining the second pressure of one or more positions each time a lifting process is completed, and each position has multiple second pressures. If only multiple second pressures of a single position are obtained, if the average value of the multiple second pressures of this position is higher than the second preset threshold, the sealing of the zero-order difference window is determined to be qualified; if the average value of the multiple second pressures of this position is lower than the second preset threshold, the sealing of the zero-order difference window is determined to be unqualified. If the second pressures of multiple positions are obtained, if the average value of the multiple second pressures of each position is higher than the second preset threshold, the sealing of the zero-order difference window is determined to be qualified; if the average value of the multiple second pressures of at least one position is lower than the second preset threshold, the sealing of the zero-order difference window is determined to be unqualified.

[0092] In this embodiment, after determining that the sealing of the zero-order difference window is qualified, it also includes: determining whether the Hall signal of the vehicle is correct; if the Hall signal is incorrect, controlling the zero-order difference window to perform a complete lifting process and completing the Hall number correction through self-learning; after completing the Hall number correction, self-inspection of aesthetics and sealing is performed again.

[0097] If the first gap and the face difference are higher than the first preset threshold, it is determined whether the glass is flush with the window frame.

[0098] Furthermore, the control module can also be used to control the zero-order difference window to perform a complete lifting process after determining that the glass is flush with the window frame;

[0099] The acquisition module is further used to acquire the first pressure exerted on the sealing strip of the vehicle door opening when the zero-order difference window is in a closed state;

[0100] The determination module is further configured to determine that the sealing performance of the zero-order difference vehicle window is qualified if the first pressure is higher than a second preset threshold value;

[0101] If the first pressure is lower than the second preset threshold, it is determined whether the sealing performance of the zero-order difference window is qualified.
