Description

Field of the Invention [0001] The present invention relates to a method and apparatus for controlling a sunroof,

The present invention relates to sunroof control and, more particularly, to a method and apparatus for preventing false reverse during operation of a sunroof.

There are many convenience devices for the driver and passengers in the cabin room of the car. Such convenience devices include electronic devices such as HUD, navigation, AV system, sunroof, as well as mechanical devices such as ashtrays and cup holders, and these electronic devices are increasing with the development of technology.

The sunroof is installed on the ceiling of the vehicle to light outdoor natural light, and it also serves as a passage for indoor and outdoor air exchange because it can be opened and closed.

As with the power window, the sunroof can be opened and closed automatically. If hands or foreign objects are caught between the closed sunroofs, there is a risk of injury or damage to the sunroof. Therefore, vehicles equipped with sunroofs or power windows are required by law to be equipped with anti-seizure function in preparation for such interference.

Conventional anti-jamming function measures the current of the motor and detects the change of the current due to the resistance of the rotation of the motor when the object is caught. It detects the jamming and reverses the motor.

FIG. 1 is a flow chart of a method for recognizing such a conventional object fit.

During the initial start of the sunroof or power window, the motor runs suddenly, so the motor speed remains unstable for a while. Therefore, it is determined whether the masking period is the initial masking period in order not to perform the anti-jamming operation for a predetermined period of time (S110), and the anti-jamming operation is not performed in the masking period.

If it is not the initial masking period, the speed of the sunroof or the power window is calculated, which can be calculated instead of the rotational speed of the motor (S120).

The rotation speed of the motor is calculated, and the difference is compared with the rotation speed at the time of normal operation, and the difference value is accumulated (S130).

The jamming reference value is set to a constant reference value through experiments (S140). If the insertion reference value is too small, it is too sensitive to the speed change to cause a malfunction. If the insertion reference value is too large, the anti-jamming function may not work even if the actual object is stuck.

(S150). If the jamming recognition value is greater than or equal to the jamming recognition value, the jamming state is updated (S160), and the sunroof is reversed so that the object is stuck in the sunroof This prevents it (S170).

Recently, the sunroof or power window is set to operate not only when the engine is started, but also when the engine is off. When the motor is operated while the starter is off, the motor for starting the engine is operated when the engine is cranking, that is, when the engine is started when the sunroof or the power window is operating. In such a case, Or an error occurs if the power window recognizes the input using voltage or current.

In the event of such an error, there is a problem in that the object is not caught, but the anti-squeaking option is activated and the sunroof or power window is reversed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus and method for preventing a sunroof or a power window from being reversed due to a voltage drop at the time of starting a sunroof or an engine in a state that the starter is off, The purpose.

The objects of the present invention are not limited to the above-mentioned objects, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.

The method of preventing false reverse according to one aspect of the present invention includes the steps of increasing a voltage drop count when a voltage drop due to engine cranking occurs and comparing the voltage drop count with a preset voltage drop set count value; Comparing the difference between the rotational speed of the motor and the rotational speed of the motor in the steady state with a preset rotational speed threshold when the voltage drop count is greater than the voltage drop set count; Increasing the false reverse prevention logic execution count when the difference in the rotational speed is equal to or greater than the rotational speed threshold; Comparing the false reverse prevention logic execution count with a preset threshold value; And turning on the anti-reverse logic if the comparison result indicates that the anti-reverse prevention logic execution count is greater than the threshold value.

According to another aspect of the present invention, there is provided a front loop anti-reverse device comprising at least one processor, the processor including: calculating an operating speed of a sunroof; Comparing the operation speed with a sunroof operation speed in a steady state and accumulating the difference value to calculate a wake-up recognition value; Decreasing the preamble recognition value or decreasing the predetermined preamble recognition reference value when the on-state anti-reverse logic is in the ON state; And stopping or reversing the sunroof when the value of the occlusion detection value is equal to or greater than a predetermined idle detection reference value, thereby preventing false reverse of the sunroof.

According to the present invention, even when the motor for starting the engine is operated by operating the sunroof or the power window and then turning on the starter key or by pressing the engine start button while the starter is not turned on, So that the sunroof or the power window does not cause a false inversion at the time of engine cranking.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving them will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. As used herein, the terms " comprises, " and / or "comprising" refer to the presence or absence of one or more other components, steps, operations, and / Or additions.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 shows a flow diagram of a method for implementing false anti-tamper logic according to an embodiment of the present invention.

When a user operates a sunroof (hereinafter, the sunroof is described, but the operation principle may be applied to the same power window and similar devices) while the vehicle is not running, the engine cranking occurs A voltage drop occurs (S210).

If a voltage drop occurs, the number of times the voltage drop occurs is counted and stored as a voltage drop Cnt value (S220), and the voltage drop Cnt value is compared with a preset count threshold value (S230).

At this time, the time interval for measuring whether a voltage drop has occurred and the count threshold can be set in advance through experiments. For example, if the voltage drop Cnt exceeds 3 by measuring at intervals of 1 millisecond (ms) or 0.1 second It can be set to operate the inversion prevention logic.

Since the malfunction may occur if the erroneous prevention logic is activated whenever a voltage drop occurs, the number of times the voltage erroneous occurs is counted, and it is determined whether the erroneous logic is operated only when the erroneous erroneous logic is operated more than a predetermined number of times. At this time, the set threshold value can be determined experimentally by using the optimum value which does not cause malfunction.

If the voltage drop Cnt does not reach the preset count threshold, the voltage drop detection is not canceled but the voltage drop detection is canceled. The Cnt (count) value is increased (S240) The voltage drop detection is canceled only when it is larger than the count threshold (S242) and greater (S246).

As in the case of voltage drop setting, it is necessary to increase Cnt of voltage drop detection for a certain period of time and release it after a certain time elapses to prevent malfunction. The set count threshold can be determined experimentally.

For example, if the threshold value of the recognition release setting count is set to 3, if the voltage drop recognition release count value becomes 4, the loop for recognition release is released too soon and a malfunction occurs. However, if the recognition release setting count threshold value is set to 4 If the Cnt value is 5 when the voltage drop detection is released, if it exits the loop and performs a normal operation, it is possible to set the optimal unreceivable setting count threshold value to 4 by repeating this experiment.

If the voltage drop Cnt value is larger than the set count value, a step of comparing the conditions to execute the false reverse prevention logic is executed.

First, a difference value between the rotation speed of the motor when the sunroof operates normally and the rotation speed of the current motor is calculated and compared with the preset difference value (S250).

If the rotational speed difference value is less than the set value, the logic execution Cnt (count) value is decreased (S270) and the counter value is compared with 0 (S272). On the other hand, if the logic execution Cnt value is not 0, step S250 is repeated to compare the rotation speed difference within the set value.

If the rotational speed difference value is greater than or equal to the preset value, the logic execution Cnt value is increased (S260). If the rotational speed difference value is greater than or equal to the preset value, the logic execution Cnt value is increased by more than a predetermined number If it is determined that the speed difference is within the set value (S250), the false reverse prevention logic is executed (S264).

In the case of recognizing or releasing the voltage drop and setting the count value to be repeated a predetermined number of times in all cases of operating or stopping the misinterpretation logic, the next operation is executed. Therefore, Even if the unexpected value appears temporarily, it is possible to reduce the malfunction of the logic.

Fig. 3 shows a flow chart of the anti-reverse logic that actually operates when the anti-anti-reverse logic is executed in this manner.

(S330), calculating the rotational speed of the motor (S320), and calculating the jamming recognition value and the jamming reference value (S330 and S340) are the same as those of the conventional invention. Then, the above-described anti-reverse prevention logic It is determined whether the false-reverse prevention logic has been executed in the method for executing (S342).

When the anti-reverse prevention logic is executed, it corrects the noise recognition value and prevents the reverse of the sunroof due to the voltage drop due to engine cranking.

When the voltage drop occurs, the rotation speed of the motor decreases. Therefore, the difference value with the normal speed suddenly increases. Therefore, the recognition value increases as if the object is sandwiched and it is recognized that the object is actually sandwiched. To prevent this.

The method of decreasing the chord recognition value may be a method of measuring the rotational speed drop in the engine cranking through an experiment and multiplying the damping coefficient by subtracting the value of the engine speed or attenuating it at a constant rate.

If the intrusion recognition value is determined according to whether the anti-reverse prevention logic is enabled / disabled, the intrusion recognition value is compared with the interference reference value (S350). If the intrusion recognition value is equal to or greater than the threshold value, (S360) and inverts the sunroof (S370).

Even if the voltage drop of the vehicle occurs due to the engine cranking through the above-described method, it is possible to prevent the sunroof from erroneously recognizing the object as an object and reversing it.

On the other hand, the false reverse prevention method of the sunroof anti-reverse device 400 according to the embodiment of the present invention can be implemented in a computer system or recorded on a recording medium.

The computer system may further include a network interface 429 coupled to the network. The processor 421 may be a central processing unit (CPU) or a semiconductor device that processes instructions stored in the memory 423 and / or the storage 428.
