The present invention relates to a window system endurance test method of a vehicle, and more particularly, to a window system endurance test method of a vehicle in which an inversion of a window can be detected, thereby improving the reliability of the endurance test result.

Currently, most power window systems have been a manual method in which the window is moved by powering the motor while the user presses the switch. The endurance test of the manual power window system was repeated for the rising and falling of the window, but with a predetermined number of times with a predetermined time interval between the rising and falling. Then, check the motor and regulator for any abnormality during the repetition process. Therefore, it is possible to check whether the motor and the regulator have repeatedly operated for a prescribed number of times to recognize the durability, and when an abnormality occurs, it is possible to know how many times the abnormality occurs after the operation.

On the other hand, in recent years, an automatic power window system in which a window is automatically opened and closed by receiving an input signal when a driver operates a switch (not a continuous operation) has been increasingly used. The automatic power window system has a function to stop the closing operation of the window and lower it by a specified position to detect an object being caught in order to prevent the user's body from being caught by an open gap during automatic window lift.

Due to the jamming function as described above, the automatic power window system cannot apply the window durability test method applied to the conventional manual power window system as it is.

This means that even though the manual method has a slight obstacle to the lifting of the window due to an assembly error, the window is fully raised and then fully lowered. Therefore, the endurance test of simply measuring the cumulative number of lifting operations can be applied. If a failure occurs while the window is rising, it is judged as being jammed and reversed.

Regulators, motors, and even door panels and window channels of power window systems are deformed due to abnormalities in form, fastening strength or engagement as time passes and the number of actuations increases. The inversion such as occurs intermittently, but the conventional endurance test method does not consider the inversion as described above, it could not be detected even if the window is lowered by the inversion during the test.

Therefore, if an inversion occurs, the window lowers and stops to the reverse falling position. If the falling signal following the rising signal before the reverse descent is transmitted by the periodic descent signal, the window is lowered again from the reverse falling position, and it is as if it was operating normally. Cause the same result. Therefore, when this type of operation is repeated, the actual number of repetitions that satisfy the endurance conditions may not be satisfied, but the test apparatus may be counted to satisfy the set number of repetitions. There was a problem.

Accordingly, the present invention has been made to solve the above problems, the window system of the vehicle to obtain a more accurate test results by performing the endurance test in consideration of the inversion operation that may occur in the automatic power window system The purpose is to provide a durability test method.

The present invention for achieving the above object,

In the manual power window system endurance test method consisting of a window rising power supply step, a rising pause phase, a window falling power supply phase, a falling pause phase,

In the step of supplying the window lowering power, a window misrecognition determining step of determining whether the window is inverted by a signal generated by the window movement detection sensor installed in the door window channel is performed.

Counting the normal number of times when it is determined to be normal in the step of determining whether the window is inverted, and performing normal and inverted operation counts to count the number of inversions when it is determined that the inversion has occurred,

After the normal and inverted operation count count step, if the counted normal operation count is equal to the reference number set as a reference value for acknowledging durability, it is determined that durability and operation performance are satisfied, and the inversion is set in advance. If the recovery time is greater than the limit, the final judging step is performed to determine that the operating performance is poor.

If the final determination step does not meet the conditions of the final determination, it characterized in that the logic cycle step of performing the window rising power supply step again.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

First, as shown in FIG. 1, the test apparatus used in the present invention includes a window regulator 10, a motor 20 for operating the regulator 10, and a window and a door lifted by the regulator 10. In the window channel 5, the window movement detecting sensor 50 mounted at a position slightly higher than the window inversion lowering position A, and the window raising and lowering to supply the window raising and lowering power to the motor 20 periodically The control unit 30 receives the signal from the window movement sensor 50 and counts the number of times of normal operation of the window and the number of inversions of reverse operation, and the operation of the entire device, that is, the operation of the window raising and lowering control unit 30. It is composed of a test control unit 40 for controlling, except that the window movement sensor 50 is additionally provided, there is a difference in the control logic of the control unit 40 only the configuration of the device In there is no difference between the present invention it will be charged only as to how.

The method of the present invention proceeds as follows.

Basically, it proceeds in the same way as the existing manual power window endurance test method. That is, as shown in FIG. 3, the window rising power supply step S1, the rising pause step S2, the window falling power supply step S3, and the falling pause step S4 are repeatedly performed.

In the window lowering power supply step (S3), a window misrecognition determination step (S5) is performed.

On the other hand, determining the inversion of the window (S5) by the signal transmitted from the window movement sensor 50 is performed as follows.

As shown in FIG. 2, in the case of normal operation, a signal transmitted from the window movement sensor 50 is periodically generated.

However, when an inversion occurs, the window is reversed and the window movement detecting sensor 50 generates a falling detection signal earlier than normal, thereby generating an abnormal signal at the position B in FIG. 2.

Therefore, the detection signal which is not in the normal signal cycle as described above and is located at an arbitrary position between the rising signal and the falling signal before the falling signal indicates that the reverse fall has occurred due to the inversion.

That is, in normal operation, the detection signal of the window movement detection sensor comes in at the same time interval, but if it is inverted, the falling detection signal is generated earlier than normal. Therefore, subtracting the time from the current falling detection signal generation time to the descending once again after the normal rise should be the same as the previous falling detection signal generation time.

Therefore, if the time calculated as described above is the same as the previous falling sensor generation time is determined to be normal operation, if it is small is determined to be inversion.

That is, it is judged to be normal when it compares {(current falling detection signal generation time)-(rising movement time + rising pause time + falling movement time + falling pause time)} with {the previous falling detection signal generation time). If it is small, it is judged as an inversion.

Subsequently, if the operating state is normal, the normal count is counted, and if the incorrect count is counted, the number of incorrect counts is counted. )

Then, if the normal number of times of operation counted in the step is equal to the set reference number, it is determined that the durability and performance are satisfactory, and the test operation is stopped.

The reference frequency is a value set by the designer in consideration of how many times the endurance test can endure the window system to function as a normal product.

In addition, when the number of inversions counted in the step is larger than the preset inversion limit number, it is determined that the operation performance is poor, and the test operation is stopped.

In other words, even if the normal operation number of the test operation has not yet reached the above standard number that can be recognized as durability, the occurrence of the error inversion over the set limit number of inversion means that it does not function as a normal product. Determination of badness and no further unnecessary endurance test (S7)

On the other hand, if the normal operation count counted in the final determination step (S7) is less than the reference number or the inversion number is less than the inversion limit number of times, the window rising power supply step (S1), which is the first step, is performed again. . (Logic cycle step; S8)

As described above, according to the present invention, more accurate test results can be obtained by performing an endurance test in consideration of an inversion operation that may occur in an automatic power window system.

In addition, there is an advantage that the unnecessary test is not repeated by stopping the endurance test immediately if it is determined that the operation is inferior by counting the inversion operation count.
