Technical Field
The invention relates to the field of vehicle control, in particular to a control method for preventing frameless vehicle door opening glass from being scratched.
Background
Due to the requirement of appearance design, the car doors of sports cars and saloons are often designed without an upper frame. When no frame door was opened, in order to guarantee that the door can open smoothly, window glass need descend a section distance simultaneously, because control logic and cost restriction cause a lot of frameless motorcycle types to open the door fast, the scraping appears in window glass and last window frame.
There is the data to show, and the control logic that current frameless door glass that opens the door descends is: after the vehicle is unlocked, a door handle is pulled, the door is opened, a door opening signal is fed back to the BCM when the door is opened, the BCM sends a glass descending instruction to the glass lifter ECU through the LIN, and the glass lifter executes descending action. Since the glass drop occurs after the door is opened, there is a problem that the glass does not completely drop to the position when the door is opened quickly, resulting in scratching of the window glass and the upper sash guide. In order to deal with the problem, some host factories can reduce the insertion amount of the glass and the upper window frame guide rail as much as possible, which may cause the problems of poor sealing, water leakage, high-speed wind noise and the like.
Chinese patent document CN102140878A discloses a glass microlitre and micro-drop system for a door without an upper frame and a control method thereof. The automobile door anti-pinch device comprises an automobile body controller, an automobile door switch, an automobile window lifter and an automobile door anti-pinch module, wherein the automobile body controller is connected with the automobile door switch; the vehicle body controller controls the window regulator after detecting the opening and closing state of the door switch. The control method comprises the following steps that when a vehicle body controller detects that a vehicle door switch is switched from closed to open, a vehicle window lifter is controlled to lift/lower a vehicle window glass to a position which is a set value away from a vehicle roof within a set time range; when the automobile body controller detects that the automobile door is opened and closed, the automobile body controller controls the automobile window lifter to lift the automobile window glass to the top. Above-mentioned technical scheme can't in time react when the user opens the door fast, easily leads to the problem of door window glass and last window frame guide rail scraping.
Disclosure of Invention
The control method for preventing the frameless car door opening glass from scraping mainly solves the technical problem that the original frameless car door opening glass does not descend in time, does not need to add new hardware, divides the door opening glass micro-descending action into two times under the condition of the existing hardware through a new logic, can solve the door opening scraping problem, can also ensure the sealing problem of a car in the processes of locking and driving, has better reliability and lower cost, does not need to add extra cost while improving the product quality, and improves the product competitiveness.
The technical problem of the invention is mainly solved by the following technical scheme: the invention comprises the following steps:
(1) after the vehicle is awakened and unlocked, the door glass begins to perform one-time micro-landing;
(2) pulling a door handle, and opening the door and starting to perform secondary micro-reduction on door glass;
(3) closing the vehicle door, and starting to perform microlitre for the vehicle door glass;
(4) after the safe driving judgment is carried out, the vehicle door glass starts to perform secondary microlitre;
(5) after the vehicle stops, the door glass begins to perform one-time micro-drop;
(6) pulling a door handle, and opening the door and starting to perform secondary micro-reduction on door glass;
(7) closing the vehicle door, and starting to perform microlitre for the vehicle door glass;
(8) the car is locked and the door glass begins to perform a second microliter. The glass rises from the one-time fine-falling position to the top dead center, and then one cycle is finished.
Preferably, the first fine lowering is to lower the door glass from the glass top dead center to a first fine lowering position, and the second fine lowering is to lower the door glass from the first fine lowering position to a second fine lowering position.
Preferably, the first microliter is to raise the door glass from the second microliter position to the first microliter position, and the second microliter is to raise the door glass from the first microliter position to the glass top dead center.
Preferably, the safe driving determination in step 2 includes: the driver or passenger locks the central lock or the vehicle starts to speed up to the speed set value of the automatic lock falling.
Preferably, the glass top dead center is determined by the cooperation of the window frame guide rail and the roof sealing strip.
Preferably, the insertion amount of the door glass is the sum of a descending dimension a of the primary fine lowering glass and a dimension b of the upper sash guide rail, which is required to descend when the glass slides out of the primary fine lowering position at the moment of opening the door. After the driver or the passenger finishes the action of opening and closing the door to get on and off the vehicle, the vehicle is locked by pressing a key or a central control, or the speed of the vehicle reaches a locking set value, the glass rises to the top dead center from the one-time micro-drop position, and the depth of the glass entering the groove is changed into a + b, so that the problems of water leakage or high-speed wind noise are avoided.
Preferably, the secondary micro-drop descending amount is the sum of the size b of the descending required for sliding the glass out of the upper window frame guide rail from the primary micro-drop position at the moment of opening the door and the size c of the descending required for sliding the glass out of the upper window frame guide rail from the secondary micro-drop position. Assuming that the insertion amount of the upper glass is designed to be 8mm in a + b, and 5mm in a first micro-drop, then 3mm in b; when the vehicle door is opened, the distance from the glass falling from the a to the sliding-out b is 3mm, and the distance is shortened by 2.7 times compared with the distance from the top dead center to the sliding-out b, which is 8 mm; the glass descending speed is generally 100mm/s to 180mm/s, and according to the minimum descending speed (because the speed is the smallest, the scraping is easier to occur), the glass needs 80ms when the glass descends for 8mm, and only 30ms when the glass descends for 3mm, the time is reduced by 50ms, and about 2/3 time is saved.
Preferably, the angle when the vehicle door is opened is inward inclination, and the glass slides out along the upper edge of the glass along the door opening movement direction when the vehicle door is opened. When the door is opened, the glass slides out of the window frame guide rail along the door opening movement direction along the upper edge of the glass instead of the positive Y direction, and when the insertion amount is small, the glass has the tendency of automatically sliding out when the door is opened, so that the interference with the window frame guide rail is avoided.
The invention has the beneficial effects that: need not to increase new hardware, through a new logic, under the condition of current hardware, the glass that opens the door descends the action a little and has been divided into twice, can solve the scraping problem that opens the door, can guarantee again that the vehicle is locking the car and the sealed problem of in-process that traveles, and the reliable performance is better, and the cost is lower, when having promoted the product quality, need not to increase extra cost, has improved product competitiveness.

Wherein, the glass top dead center 3 is determined by the matching of the window frame guide rail 1 and the roof sealing strip 2.
(2) And pulling the door handle, opening the door and simultaneously starting to perform secondary fine lowering on the door glass, and lowering the door glass from the primary fine lowering position 4 to the secondary fine lowering position 6.
(3) When the door is closed, the door glass starts to perform one microliter, and the door glass is raised from the secondary micro-drop position 6 to the primary micro-drop position 4.
(4) And (4) carrying out safe driving judgment, namely after a driver or a passenger locks according to the central lock or the vehicle starts to accelerate to a speed set value of automatic lock falling, starting to perform secondary microlitre on the door glass, and lifting the door glass from the primary microlitre position 4 to the glass top dead center 3.
(5) After the vehicle stops, the door glass starts to perform one fine lowering, and the door glass is lowered from the glass top dead center 3 to the one fine lowering position 4.
(6) And pulling the door handle, opening the door and simultaneously starting to perform secondary fine lowering on the door glass, and lowering the door glass from the primary fine lowering position 4 to the secondary fine lowering position 6.
(7) When the door is closed, the door glass starts to perform one microliter, and the door glass is raised from the secondary micro-drop position 6 to the primary micro-drop position 4.
(8) And locking the vehicle, starting to perform secondary microlitre on the door glass, and lifting the door glass from the primary microlitre position 4 to the glass top dead center 3, so that one cycle is ended.
The window frame guide rail 1 and the roof sealing strip 2 are matched to determine the glass top dead center 3 at the highest position where the glass can rise, when the door glass is positioned at the glass top dead center 3, the door glass is tightly matched with the roof sealing strip 2 to ensure the sealing performance, and the sealing performance is related to the glass insertion amount.
Wherein a is the descending size of the primary micro-descending glass, b is the size of the descending required for the glass to slide out of the upper window frame guide rail 1 from the primary micro-descending position 4 at the moment of opening the door, and c is the size of the descending required for the glass to slide out of the upper window frame to the secondary micro-descending position 6. a + b represents the amount of glass inserted, and b + c represents the amount of secondary decrease in the amount of glass. Assuming that the insertion amount of the upper glass is designed to be 8mm in a + b, and 5mm in a first micro-drop, then 3mm in b; when the vehicle door is opened, the distance from the glass falling from the a to the sliding-out b is 3mm, and the distance is shortened by 2.7 times compared with the distance from the top dead center to the sliding-out b, which is 8 mm; the glass descending speed is generally 100mm/s to 180mm/s, and when the speed is minimum, scraping is easier to occur, the glass is 80ms when the glass descends for 8mm, and the glass descends for 3mm, only 30ms is needed, the time is reduced by 50ms, and 2/3 time is saved. And because the angle when the door is opened is inward inclination, when the door is opened, the glass does not slide out of the window frame guide rail in the positive Y direction, but slides out along the opening movement direction of the upper edge 7 of the glass, when the insertion amount is small, the glass has the tendency of automatically sliding out when the door is opened, thereby avoiding the interference with the window frame guide rail,
the scheme has passed the real vehicle verification and can effectively avoid scraping. When the driver or the passenger finishes the action of opening and closing the door to get on and off the vehicle, the vehicle is locked by a key or a central control, or the speed of the vehicle reaches a locking set value, the glass rises to the upper stop point 3 from the primary micro-drop position 4, and the depth of the glass entering the groove is changed into a + b, so that the problems of water leakage or high-speed wind noise are avoided.
