Description of the Invention [Technical Field] The present invention relates to a method for preventing and preventing the opening and closing of a handle, and more particularly to a method for preventing loss of a vehicle opening and closing body using current detection. [Prior Art] In recent years, due to the development of electronic technology, some of the opening and closing bodies on the vehicle have been changed from fully automatic to fully automatic, for example, electric windows, sunroofs, etc., thus giving the user a lot of convenience. However, according to the US National Highway Safety (NHTSA) 1997 safety accident survey, there were 499 emergency cases in the United States in four years due to the operation of automotive electric accessories. And /' Zhongda, force 93% of the victims are from the electric window of the car, 32% of the victims are 2 years old at the age of '32% of the victims are younger than 15 years old. Since the two kings are not protected by Bao Xun, the car electric window anti-pinch has become an urgent issue. Therefore, the United States and Europe have enacted regulations FMVSS 118 and 74/60/EEC to force the automatic opening and closing of windows to have anti-clamping force. 1防N or less anti-pinch function. The detection methods of the conventional anti-pinch detection system can be divided into Touchless Direct Systems, Seal Integrated Systems and Indirect DetecH〇n Systems. Some sensors (such as infrared super-a wave 19-induction) to achieve automatic anti-pinch function, but because the sensor is expensive, its cost is relatively higher. The sensor system of the sealed integrated system is integrated in the bezel frame. When something touches the strip, the motor will immediately generate a reversed 彳§ number to allow the anti-pinch system to start A-in, and then move Protect the child or the adult woman. However, because the rubber strip is limited by the installation ring, the display factor, the detection state and its frequent use conditions, the service life is limited, / and the cost is also high. The indirect detection system uses Hall induction technology, and it is necessary to test the skin precision and the cooperation of the mechanism to make the anti-pinch perfect. Therefore, if the mouth of the "in case" can not cooperate or there is fatigue, it will affect the anti-pinch and cause high (four) pinch rate, so this technology still has improvement. In summary, the above-mentioned conventional technology has high cost and short life. The mechanism is complicated and the precision of the motor is high. Therefore, it is very urgent to develop a method for preventing the clamping of the vehicle opening and closing body, thereby improving the aforementioned deficiency. [Invention] The object of the present invention is to provide a vehicle opening and closing body. The anti-pinch method is effective for achieving the automatic anti-pinch function of the vehicle opening and closing body. The X-Ming of the present invention provides a method for preventing and opening the vehicle opening and closing body, thereby effectively recognizing when the vehicle opening and closing body is subjected to Vibration and when _ • for the vehicle opening and closing body to the foreign object, thus reducing the false loss prevention rate. According to the above object of the present invention, the anti-static side of the wheel opening and closing body is effectively used to effectively achieve the function of the female full anti-pinch, and can be avoided The vehicle opening and closing body is erroneously prevented from being caught by the vibration. According to a preferred embodiment of the present invention, in the anti-trapping method of the vehicle opening and closing body of the present invention First, a preset threshold value is provided. Then, the running current of the motor is detected, and at least two current detecting values are obtained according to the time-time t timing, wherein the motor drives the moving member of the vehicle opening and closing body along a moving stroke. Move to the 6 1324216 fully closed position. Then, perform the _ normal anti-pinch mode to determine whether the moving part is caught in the foreign object'. In the normal anti-pinch mode, the first judgment step is performed to determine the last current detection value minus the most Whether the current detection value is greater than the preset threshold value. When the result of the first determination step is YES, a large vibration anti-pinch mode or a small vibration anti-pinch mode is performed. In the large vibration anti-pinch mode, firstly The time point at which the last current detection value is detected is forwarded to a preset time period, wherein the preset time period is greater than the aforementioned time travel. Then, the last current detection value (h) and the maximum value in the preset time period are found. a current detection value (la) and a minimum current detection value (Ib). Next, a second determination step is performed to determine (1._1〇_(1 Guang^ is greater than or equal to the preset) Depreciation. When the result of the second judging step is YES, the anti-missing action of the motor is started. In the small vibration step, the third judgment (4) is performed to determine the last current detection value minus the first current detection. After the value is divided by the value of 2 'is greater than or equal to the intermediate point current value of the two minus the pre-accuracy value. When the result of the third (four) step is YES, 'receive the motor's anti-pinch action. According to the present The day m is preferably _, the current detection value is at least two current detection values, and the normal anti-pinch mode includes at least: the fourth determination step of 'individually calculating the value of each adjacent three current detection value streams minus The first current value of the first current detection value is greater than the result of the first determination step and the fourth determination step, the Tianda vibration anti-pinch mode or the small vibration mode. -疋, 'The above is entered In addition, the normal anti-pinch mode of the present invention is _ which is to move the stroke to the full-close position to the anti-pinch mode of the first-stage anti-trap mode, and the first section of the anti-missing 7 1324216 A, a second section of the anti-pinch zone, and - The third section of the anti-pinch zone. The first section of the anti-pinch zone includes a first time travel (tl) 'the second section of the anti-pinch zone includes a second time travel (t2), and the third section of the anti-pinch zone includes a third time trip, where t3>t2> Tl. The preset threshold value is set to a first preset threshold value, a first preset threshold value and a first in the first section of the anti-pinch zone, the second section of the anti-pinch zone, and the second section of the anti-pinch zone. The third preset threshold value is that the first preset threshold value is greater than the second preset threshold value, and the second preset threshold value is greater than the third preset threshold value. Therefore, the application of the present invention can effectively achieve the automatic anti-pinch function of the vehicle opening and closing body without using an inductor; it can effectively recognize when the vehicle opening and closing body is subjected to vibration and when the vehicle opening and closing body is clamped to the foreign object, Therefore, the false anti-clamp rate is reduced. [Embodiment] The present invention utilizes a hardware circuit of an electronic control unit (ECU) of a vehicle, and is equipped with a shunt device to measure a change in the operating current of the motor, thereby performing analysis and judgment to achieve prevention. The function of the clip. In general, when a moving member of a vehicle opening and closing body (such as a sunroof, a power window, or the like) is displaced in the closing direction when the moving stroke is displaced, if the obstacle is hit, the motor running current for driving the moving member is remarkably improved. Therefore, according to this characteristic, the opening and closing body (for example, a sunroof, a power window, etc.) can be prevented from being pinched by detecting a change in current. Please refer to FIG. 1 , which is a schematic diagram showing the total stroke L of the motor running current for driving the opening and closing body of the vehicle. At point B1, the motor is started to move the opening and closing body (such as the sunroof, power window, etc.). When the movement stroke of the 13 1324216 piece is displaced in the closing direction, the movement will rise instantaneously when the bowl is moved. When the moving parts arrive at the full position of the .11 motor, the running current of the motor will rise instantaneously.

Therefore, the function of the anti-pinch can be used to perform special analysis on the fluctuation of the electric k caused by the vibration of the vehicle, and the malfunction of the closed body, resulting in the loss of the vehicle door and the normal operation of the vehicle to open and close the vehicle. Switch function. Closed body: defense: 2nd and 3rd drawings, Fig. 2 is a diagram showing the prevention of the vehicle opening of the present invention; FIG. 3 is a diagram showing the opening and closing of the vehicle of the present invention. intention. First, the motor is started (step ι〇〇), and the moving member of the opening and closing body performs step 11G along the moving stroke D4 to the full-off=receiver' to detect that the running material of the motor as shown in the figure w/ successively obtains at least There is a current sense of two current detection values... after the 'anti-clamp determination step. The anti-pinch judging step of the present invention has a normal anti-lost mode, a large vibration anti-lost mode, and a small vibration anti-clamping normal anti-pinch mode to determine whether the moving member of the vehicle opening and closing body is cool to foreign matter (step 13A). If the situation of pinching foreign matter is not detected (ie, the judgment result of 4216 is not selected), then it is not necessary to judge other anti-pinch modes, and return to step 110 to re-detect the running current of the motor; If it is detected that there is a foreign object loss (ie, the judgment result in step 130 is YES), the large vibration loss prevention mode or the small vibration loss prevention mode is performed (step 丨4〇), wherein the large vibration prevention and loss prevention type is used. In order to detect whether the fluctuation of the motor running current is caused by the large expansion of the vehicle; the small vibration anti-clamp mode is used to detect whether the fluctuation of the motor running current is caused by the small vibration of the vehicle. The following explains the operation of the normal ^ loss mode, the large vibration anti-pinch mode, and the small vibration anti-pinch mode. • Mode Refer to Figures 2 to 4, and Figure 4 is a schematic diagram showing the travel of the motor running current after the moving parts of the vehicle opening and closing body have lost foreign objects. When the moving member is 'to a foreign object, the current detection obtained by the step U0 according to the timing of a time travel-data includes at least three current detection values. For convenience of explanation, the present embodiment is represented by a total of five current detection values A1 to A5, wherein the current is increased by A5 due to the foreign matter being caught by the moving member. In the present embodiment, first, the current difference values A3 - A1, A4 - Lu 2 A5 ~ ~ ' and the total current difference A5 - A1 are judged. Then, the anti-pinch judgment step is performed according to the current difference value and the total current difference value, that is, when (A3 - A" > 〇 and (A4 A2) > 〇 and (A5 - A3) > 0 and (A5 - A1) 〉Preset threshold value, which means that the moving object of the vehicle opening and closing body is caught in the foreign object at this time, then it is judged as loss prevention (ie, the judgment result in step 130 is YES), at this time, the large vibration anti-pinch mode still needs to be performed and/or Or a small vibration anti-pinch mode to determine whether to change the operating state of the motor (for example, reverse) to achieve the anti-pinch function. Alternatively, the present invention may also adopt another implementation judgment method, as long as it is obtained according to the sequence of 1324216 } includes two current detection values, in which the value of the threshold value is judged to be anti-sweet, and then the anti-lost mode and/or the small vibration anti-fog mode are still needed to determine the most = no change of the operating state of the motor.防—:二—二)Γ or (Α4—Α2... or (Α5-... or (Α5) ritual value, 胄有有— When the condition is established, it is judged as non-anti-collapse (ie, step 1 3 0 Judging the fruit of the fruit * not, the illusion is broken... the result is no), without changing the state of the horse for anti-pinch, also the helmet needs In the case of the pole, the movement of the moving piece D4 of the moving piece D4 of the motor is controlled as a three-stage stroke. The plan is divided into a first-stage anti-cooling zone m, including a first time travel (referred to as (1), a second anti-pinch zone D2, including a second time travel (referred to as t2) and a third anti-pinch zone (1), including There is a second itinerary (abbreviated as t3), where t3>t2>tl, and p. , n ^ ^ L and the parent-proof zone and different anti-clamping forces according to the position of the moving parts respectively There is a first preset threshold value, a second preset threshold value, and a third preset threshold value, etc. The first preset (four) value is used as the condition for starting the defense prevention in the segment defense mD1 - in the second segment The anti-pinch area is in the middle mining (4) and the second preset door value is used as a condition for judging the start of the anti-pinch. The third preset threshold value is used in the third anti-M D3 as one of the conditions for determining the anti-pinch. Because the space of each anti-pinch zone is different, the foreign body that may be lost or the body part of the person is also different, for example: the first - anti-pinch D1 can be used for anti-clamping judgment of the human finger: the second anti-pinch zone D2 can be used for anti-clamp judgment of the human arm; the third anti-pinch zone D3 can be used for anti-clamp judgment of the human body, and the human body part is soft. Different degrees, such as the finger part of the human body relative to the body part is compared to the 1324216 hard mouth, the invention presets the first preset threshold value is greater than the second preset door • plant value '帛 two preset door value preset It is larger than the third preset homing value.

The anti-pinch is activated when the first, second or third preset threshold corresponding to the anti-pinch interval (DU 12 1324216 or D3) of the position is used. The anti-pinch judgment condition of any of the aforementioned preset threshold values of '(Ic_Ib)_(Ia_Ib)g in Fig. 5 should not be satisfied. Since the current value of (Ie-Ib) is already, -! is (Ia h), the waveform in this state does not start the anti-pinch. That is to say, the moving part of the motor can be closed at this time, and the action of the trick occurs at the time of closing the window, and a large shock wave is generated. According to the above-mentioned judgment condition of the present invention, it is possible to prevent the power window from being mistakenly judged as an anti-pinch when the card is broken: Under this condition, the large shock-proof judgment mode of the present invention can also be used when (I. lb) - (Ia - lb) g 〇, the anti-pinch is activated. Assume that the point a in Fig. 5 is very close to point b, then (Ic - Ib ) _ ^ lb ) = $ The anti-pinch judgment condition of any preset threshold value may be established, and the anti-pinch is activated. That is to say, it is possible that the moving part of the motor actually encounters a foreign object or is caught in a person without any interference or slight interference. Small vibration prevention _ $ • ° month refers to Fig. 6' which shows the waveform of the judgment current against the small vibration of the present invention. The small vibration anti-pinch step is judged after the normal anti-pinch step is judged to be anti-pinch. A small vibration waveform may occur due to the encounter with the = gravel road while the vehicle is running and the opening and closing action of the motor moving member is being performed. In order to avoid the anti-clamping error caused by the rising wave band of the shock wave, the present invention obtains at least two current detection values such as · A1 and A3 'the current value in the rising band of the small vibration waveform according to the time series. (A3) After subtracting the pre-current value (A (a) and then dividing by the value of 2" is greater than or equal to Α3, Αι intermediate point current value minus 13 1324216 to the preset error value, that is, start anti-lost. That is (A3 - When a1)/2^a2—k is established, it is judged as anti-pinch; among them, A3 is the post current value, ten ai is the pre-current value, and A2 is the intermediate point current value between... and A3, where 乂 is the preset error. In other words, if the rising section of the small vibration waveform approaches a straight line, it is reported that the judgment of the small vibration anti-inflammatory mode may be satisfied, and the rising section of the right small vibration waveform approaches the opening σ. In the parabolic mode, m is further judged by the preset error value k, if the midpoint current value C1 of the line is linear and straight (as the dashed line value A2 of Fig. 6 is approximated in the error of the precaution of the present invention) Within the value and range, it is broken as anti-pinch; otherwise, it is judged as non-defense ====================================================================================================== J circuit 10, control circuit 2〇 and Lu is used for (4) motor 40 operation electric = electric two 3: _ test circuit value.
