Generally, the trunk that forms the rear part of the automobile stores ordinary parcels, emergency tools, spare tires, and emergency boxes in case of an accident. The trunk lid is called a trunk lid. The trunk lid is interrupted by a trunk lock device (e.g., a latch, a striker, etc.), which simply raises the trunk lid with less force. In recent years, a trunk locking switch is provided in the driver's seat, and when the driver operates the switch, the trunk locking device unlocks the trunk lid to open the trunk lid.

However, the movement speed of the boot lid during the automatic opening and closing of the conventional trunk is affected by the vehicle environment such as the trunk weight and inclination after the rocking switch control. For example, in the conventional art, the trunk angle and the moving speed are received from the hall sensor, and the sections are classified into the acceleration section, the deceleration section, and the constant speed section, and the duty ratio is increased, There is a technique to control the speed. In this conventional technique, the duty ratio of the PWM is increased or decreased by a predetermined ratio, so that the speed of the trunk can be controlled for each section by controlling the output of the motor.

However, in the related art, there is a problem that the opening / closing speed of the trunk can not be maintained according to the external environment (temperature, inclination, etc.) of the vehicle as a technique of increasing or decreasing the duty ratio at a constant rate. That is, in the prior art, since the speed of the power trunk is controlled regardless of the external environment, when the external environment changes during driving, a problem arises in the speed control of the power trunk.

Particularly, in the embodiment, the hall counts varying according to the vehicle environment including the change of the trunk weight, the inclination of the vehicle, the vehicle battery voltage change, and the external temperature change are cumulatively calculated per unit time. Thereafter, when the power trunk of the vehicle is opened and closed according to the cumulative calculated hole count, a PWM (Pulse-Width Modulation) DUTY) output signal and the latch and striker operation are controlled by the motor speed compensation control method for each section. This allows the trunk to open and close smoothly and safely under any circumstances by overcoming external environmental changes.

The term " module ", as used herein, should be interpreted to include software, hardware, or a combination thereof, depending on the context in which the term is used. For example, the software may be machine language, firmware, embedded code, and application software. As another example, the hardware may be a circuit, a processor, a computer, an integrated circuit, an integrated circuit core, a sensor, a micro-electro-mechanical system (MEMS), a passive device, or a combination thereof.

The pole motor 10 controls the opening and closing of the trunk by adjusting the position of a pole which is the main axis of the trunk lid. The pole motor rotation sensing unit 13 senses the motor operation such as the rotation speed and the hole count of the pole motor for controlling the opening and closing of the trunk. In the embodiment, the pawl motor rotation sensing unit 13 may be configured as a device for measuring the position of the camshaft such as a hole sensor. The Hall sensor is a device for determining the direction and magnitude of a magnetic field by using a Hall effect in which a voltage is generated in a direction perpendicular to a current and a magnetic field when a magnetic field is applied to a conductor through which current flows. In the embodiment, the Hall sensor included in the motor rotation sensing unit 13 can sense the rotational speed of the motor by counting the number of holes generated by the motor rotation. The pole motor rotation sensing unit 13 transmits the sensed hole count result and the motor rotation speed to the speed compensation control module 100 according to the interval.

The pole motor pulse width duty controller 15 receives the control signal of the pole motor 10 from the speed compensation module 100 for each section and controls the pulse width duty of the pole motor and outputs the pole motor control signal and the controlled pulse width And transfers the duty to the pole motor 10.

Striker motor 30 is connected to the back panel and the trunk floor (back panel ] to operate the boot lid striker. Trunk lid The striker latches on the pole arm latches to lock the trunk.

 The striker motor rotation sensing unit 33 senses the rotation of the striker motor 30 and senses the rotation of the motor. For example, the striker motor rotation sensing unit 33 may be provided with a hall sensor to sense the rotation speed of the striker motor by counting the holes generated by the motor rotation. The striker motor rotation sensing unit 33 transmits the detected rotation speed to the speed compensation control module 100 for each section.

The striker motor pulse width modulation duty controller 35 receives the striker motor control signal from the speed compensation module 100 for each section and controls the pulse width modulation duty of the striker motor and controls the duty ratio of the striker motor Signal to the striker motor 30.

The vehicle latch 50 is provided at the center of a trunk lead pole arm to engage the striker to perform a trunk closure operation. The latch motor driving section 51 drives the motor of the vehicle latch 50 according to the latch control signal of the speed compensation control module 100 for each section.

The latch open sensing part 53 senses a latch open signal for releasing the trunk lock when the trunk is closed, and the latch lock sensing part 55 senses a latch lock signal generated by the engagement of the latch and the striker. When the latch open signal or the latch lock signal is detected, it is transmitted to the speed compensation control module 100 for each section.

The section-based speed compensation control module 100 compares the hall count generated by the rotation of the pole motor every unit time with the hole count preset in advance, and determines the control condition of the pole motor according to the comparison result. In the embodiment, the control conditions of the pole motor may include pole motor acceleration, deceleration, stop conditions, and the like. The pole motor acceleration condition according to the embodiment is a control condition for increasing the rotation speed of the pole motor, the deceleration condition is a control condition for reducing the rotation speed of the pole motor, and the stop condition is a control condition for stopping the rotation of the pole motor .

In the embodiment, the speed compensation control module 100 for each section grasps the cumulative count of control condition judgments for each unit time (for example, 0.1 sec), and when the cumulative count of the judged control condition judgments is equal to or greater than a predetermined number, The pole motor can be controlled according to the control signal.

3 is a block diagram illustrating a data processing block of the speed compensation control module 100 according to the embodiment.

3, the speed control module 100 according to the embodiment may include a setting unit 110, a determination unit 130, and a control unit 150. Referring to FIG.

The setting unit 110 sets a reference line (reference graph) for the motor speed according to the unit time, the frame time, and the unit time for counting the holes. In the embodiment, the frame time includes at least two unit times, and includes a overlapping period in which the unit time overlaps with the frame time interval.

For example, the unit time may be T ₀ ranging from ₀ sec to 0.1 sec, T ₁ ranging from 0.1 sec to 0.2 sec, T ₃ ranging from 0.2 sec to 0.3 sec, and T ₄ ranging from 0.3 sec to 0.4 sec at a constant time interval Can be set. In this case, the frame time (frame time) can be set to a time interval comprising the time interval T ₄ to T _3, including in the unit time T ₁ in T _f1, T ₂ to T to _f2. The adjacent frame times include a certain overlap period. For example, the frame times T _f1 and T _f2 cause overlapping periods from unit time T ₂ to T ₃ . In the embodiment, the pole motor control condition is determined in the 'overlapping period' existing in the adjacent frame time, and by using the determined control condition for the cumulative counting, the pole motor speed can be controlled more precisely to approach the reference line do.

In an embodiment, the reference line represents the ideal Hall motor speed over a unit time. The reference line can be extracted from various experimental data, and can be used as reference data for determining acceleration, deceleration, and stop conditions.

The determination unit 130 determines the control condition occurring at the set frame time. For example, the determination unit 130 compares the number of the hole counts per unit time of the reference line and the number of the hole counts per unit time sensed by the pole motor rotation sensing unit 13 according to the comparison result, It can be judged. More specifically, the determination unit 130 determines

When the hall count is present in an acceleration section that is less than a predetermined number of times than the preset hole count in unit time, the pole motor control condition is determined to be accelerated, and the hall count is present in a constant velocity interval The pole motor control condition is judged as a constant speed, and when the hole count is present in the deceleration section exceeding the preset number of holes, the pole motor control condition can be determined as deceleration.

The control unit 150 counts the control conditions determined in each unit time included in the frame time. In particular, the counting unit 110 calculates the cumulative number of the control conditions determined at the set frame time.

The control unit 150 controls the pole motor, the striker motor, and the latch according to the cumulative number of the calculated control conditions under the accumulated control conditions. For example, when the acceleration condition is cumulatively counted three or more times, the control unit may accelerate the pole motor 150.

 The control unit 150 compensates the pulse width modulation duty output signal when the acceleration, deceleration, and stop conditions determined by comparing the hole count generated per unit time in the pole motor control with the preset speed count are continuously generated for a predetermined number of times or more. Speed motor can be driven. For example, the control unit 150 can stop the pulse motor rotation by stopping the pulse width modulation duty output signal when the stop condition occurs three consecutive times in a unit time.

In addition, when the height of the auto-traction pole arm is within a predetermined height, the control unit 150 raises the striker ring, and when the latch of the pawl arm is not hooked to the striker ring, can do. In addition, the control unit 150 can drive the striker motor when the latch of the pawl is hooked on the striker ring.

4 is a graph showing a reference graph of motor speed with time.

As shown in Fig. 4, when the luggage compartment lid closing operation proceeds, the speed of the pole motor has an acceleration section, a constant speed section and a deceleration section according to time. In the embodiment, each velocity section may be determined according to the number of hall counts. In the operation in which the actual trunk lid is closed, the pole arm motor is accelerated to a specific time point (T _c ) and then maintained at a constant speed, and then decelerated at a time point (T _d ) at which the hall count is different from a certain number of times. The striker motor is operated to raise the position of the striker so that the latch and the striker can be operated at the time when the trunk lid is applied with the force (T _L ) Lock coupling. In the embodiment, when the position of the striker is at the highest point, the lock operation with the latch is started. The striker can be downwardly adjusted at a time (T _sdown ) after the latch and the striker are confirmed to be locked after the force is applied to the latch (T _L ). That is, after a predetermined time for recognizing the lock of the latch and the striker, the striker motor is driven and the striker motor is downwardly adjusted again, so that the boot lid is completely closed. Embodiment the point in time at which the speed status of the pole change motor in the example (T _c, T _d), and when the striker position is raised (T _s) can be pre-set according to the number of holes counted pole motor. Although the point of time when the striker position is adjusted upward is shown as the point of time after deceleration of the pole motor in the embodiment, the present invention is not limited to this, but may be variously adjusted according to the position of the pole arm or the number of hole counts.

5A is a view for explaining an auto-trunk closure control process according to an embodiment by comparing the pawl motor rotation speed sensed by the pawl motor rotation sensing unit with a reference graph.

As shown in FIG. 5A, in the embodiment, the section-based speed compensation control module 100 measures the speed of the pole motor using the Hall sensor at each unit time, and compares it with the speed in the reference graph. For example, as recorded in the Ls (sensing line) graph, the speed of the pole motor measured at the unit time T ₁ is a, and the speed a is a value exceeding the measured value of the reference graph (L _{r )} . Therefore, the speed compensation control module for each section is judged as a deceleration condition at T ₁ .

Since the speed of the pole motor measured at unit time T ₂ is b and the speed b is a value exceeding the measured value of the reference graph, the deceleration condition is also determined at T ₂ .

Similarly, since the speed of the pole motor measured at T ₃ is c and the speed c is also a value exceeding the measured value of the reference graph, the deceleration condition is also determined at T ₃ . Embodiment, the deceleration condition is a certain value controlled to when it is determined error (for example, three times), the interval rate compensation control module 100 is slow the pole motor rotational speed as the accumulated count condition and as a result the unit time T ₄ pole The speed of the motor is reduced so that the speed d of the pole motor controlled at the unit time T4 is close to the value of the pole motor speed of the reference graph L _r . As shown in FIG. 5, when three unit times are set to be included in one frame time, the motor speed is controlled when the control conditions are accumulated in T ₃ , and the second frame The control condition is determined at each unit time included in the time. For example, it is already determined that the deceleration condition is set at T _{2 and} the deceleration condition is set at T _{3. Since} d is lower than the reference graph speed at T ₄ , it is determined that the acceleration condition is satisfied. Thereafter, the acceleration conditions are determined as unit time T ₅ and T ₆ , respectively. The accumulated counting control in the fourth frame time (T _f4) The fourth of T included in the time frame _4, T _5, 3 times with the acceleration for both in T ₆ consecutive determination because the interval rate correction control module 100 And controls the pole motor to accelerate according to the condition. Although an example of a frame time including three unit times has been described in order to facilitate the understanding of the invention, it is possible to adjust to include more unit time according to the frame time setting, and accordingly, the overlapping period in the adjacent frame time also increases .

In the auto trunk closure control system according to the embodiment, the hole counts generated per unit time are compared with preset hole counts to determine the control conditions, and the control conditions control the pulse width modulation duty of the pole motor according to the cumulative number of times , It is possible to precisely adjust the fluctuation of the pole motor speed sensed by the Hall sensor to a preset reference speed. Therefore, it is possible to control the closing speed of the trunk so as not to be affected by changes in the vehicle environment such as the weight and inclination of the trunk.

5B is a view for explaining a striker motor control process using a hall sensor according to an embodiment.

The striker is mounted on the back panel connected to the trunk floor and is configured to engage the latches of the trunk lid. 5B, when the trunk lid close control reaches a predetermined level or more near the vehicle back panel, or at a time Ts when the number of holes of the pole motor becomes equal to or more than a certain level, the position of the striker is raised . The latch and the striker are then combined at the point of time when the trunk lid is subjected to a force (T _L ). In the embodiment, when a force is applied to the lead, the striker and the latch are engaged. However, in the disclosed auto trunk, the lock engagement of the striker and the latch proceeds after a predetermined time even if no force is applied to the lead. In order to upwardly control the position of the striker, the striker motor speed momentarily represents a driving signal similar to the impulse signal. In the embodiment, even when the striker motor speed is controlled to adjust the striker position upward or downward, the hole count of the striker motor detected by the Hall sensor is compared with the hole count of the striker motor, can do. Specifically, the control conditions of the striker motor determined in the unit time (T ₁ to T ₅ ) and the frame time are counted, and the number of times the control conditions are cumulatively counted is obtained. Thereafter, by controlling the drive of the striker motor in accordance with the cumulative counted control conditions, the speed fluctuation sensed during the actual striker motor control can be controlled to approach the ideal impulse waveform S _L.

Hereinafter, the data processing procedure for the auto-trunk closure control will be described in turn. Since the function (function) of the auto-trunk close control method according to the embodiment is essentially the same as the function on the auto-trunk control system, a description overlapping with FIGS. 1 to 5 will be omitted.

6 is a data processing flowchart of the auto trunk closure control method according to the vehicle environment change according to the embodiment.

In step S610, the setting unit 110 of the speed compensation control module 100 sets a pole motor speed control condition change hole count and a control condition change time. For example, when the automatic trunk closing operation is started, the setting unit 110 sets the ideal acceleration, constant speed, and deceleration section according to the hall count and the unit time. Specifically, the point at which the pole motor changes from the acceleration to the constant velocity can be set as the point at which the hole count is counted more than a specific number, or the point at which the deceleration is changed at the constant speed as well as the number of hole counts.

In step S620, the reference line for the speed motor speed per speed section is set based on the speed change point and the hole count number set by the setting unit 110. [

In step S630, the unit time and the frame time for measuring the rotation speed and the hole count of the pole motor are set in the hall sensor provided in the pole motor rotation sensing unit 13. [

In step S640, the determination unit 130 determines the poll motor control condition by comparing the number of holes counted per unit time with the number of holes counted by the reference line. In step S650, the control unit 150 counts the cumulative number of control conditions .

In step S660, the control unit 150 controls the duty motor rotation and pulse width modulation duty according to the counted accumulated number of times. For example, in step S660, the control condition determined in each unit time included in the frame time is cumulatively counted to control the speed of the pole motor.

The auto-trunk control method and system according to the embodiment of the present invention detects a hall count of a poultter motor by using a Hall sensor, and when the power trunk of the vehicle is opened and closed, a PWM DUTY output signal, Control by motor speed compensation control method. This allows the trunk to be opened and closed smoothly under any circumstances by changing the trunk weight, changing the slope of the vehicle, changing the battery voltage of the vehicle and changing the external temperature.

Particularly, in the auto-trunk close control system according to the embodiment, the hole counts generated per unit time are compared with preset hole counts to determine the pole motor control conditions such as acceleration and deceleration stop, And controls the pulse width modulation duty of the pole motor according to the number of times. This makes it possible to precisely adjust the fluctuation of the speed of the pole motor sensed by the Hall sensor to a preset reference speed. Therefore, it is possible to control the closing speed of the trunk so as not to be affected by changes in the vehicle environment such as the weight and inclination of the trunk.

It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It is not limited to the embodiment.
