On the other hand, the priority number is not assigned to the unlocking switches (151-154), and the unlocking driving step is to drive control of the unlocking driving motor of the driver's door separately, and the unlocking driving motor of the remaining doors Drive control at a time, or individually unlocking drive control for all doors of the vehicle.

Hereinafter, a method of controlling a door locking and unlocking of a vehicle according to another embodiment of the present invention will be described in detail with reference to FIGS. 5 and 6. do.

5 is a flowchart illustrating an embodiment of a vehicle door locking and unlocking method of a card key or fob key method applied to the present invention, and FIG. 6 is a card key or fob key method applied to the present invention. It is a flowchart for explaining another embodiment of the vehicle door locking and unlocking method.

Door locking and unlocking control method of the vehicle of the present invention includes the steps of (S500 or S600) largely detect the approach of the card key or the fob key that the user is carrying; And an unlocking driving step (S510-S560 or S612-S616) for selectively driving and controlling the door driving motor by the user operating the door button switch.

In this case, the door button switch unit is provided with unlocking switches corresponding to the number of vehicle doors to selectively unlock each door of the vehicle. As shown in FIG. 5, the individual unlocking switches have priority numbers. In operation S510, when the one door unlocking switch is operated and an unlocking signal is received (S520), the driving motor for driving the corresponding door is unlocked and driven (S530). If the unlocking signal is continuously received from the operated door unlocking switch even after the unlocking operation of the driving motor for driving the door (S540), until the set time has elapsed (S560), the operated Unlocking and driving all of the driving motors corresponding to the subordinate unlocking switches of the unlocking switch (S550).

Alternatively, the door button switch unit is provided with unlocking switches corresponding to the number of vehicle doors to selectively unlock each door of the vehicle, and the unlocking switches are assigned priority numbers (S510). If one unlocking switch is operated and an unlocking signal is received (S520), the driving motor control unit unlocks the corresponding driving motor (S530) and is set even after the unlocking driving of the driving motor for driving the corresponding door. If the unlocking signal is received from the operated door unlocking switch continuously (S540), the drive motor corresponding to the priority individual unlocking switch of the operated unlocking switch until the set time elapses (S560). It characterized in that the unlocking driving (S550).

More specifically, as shown in FIG. 5, in the vehicle key locking and unlocking method of the card key or the fob key method of the present invention, the card key or the fob key 50 is approached by checking whether the vehicle door is approached. If yes, go to step S510, and if not already performed, step S500 is performed until approaching. When the card key or the fob key 50 approaches the door of the vehicle in step S500, the priority determined for each of the unlocking switches 151 to 154 provided in the remote control switch unit 100 is checked (S510). It will be apparent to those skilled in the art that prioritizing each of the unlocking switches 151-154 and deciding a vehicle door corresponding to each unlocking switch would be desirable at the time of manufacture of the product. However, since the user may set the priority after the vehicle leaves the vehicle, it will be obvious to those skilled in the art, and thus, the detailed description thereof will be omitted and the present invention will be understood as a step of checking the predetermined priority for convenience.

As described above, when the driver or the user operates, for example, the driver's seat door unlocking switch 151 of the door button switch unit 170 in a state where the corresponding doors and the priorities of the unlocking switches 151 to 154 are determined. In operation S520, the driver's door unlocking driving signal is generated and transmitted. When the driver's door unlocking driving signal is generated by the door button switch unit 170 and received by the driving motor controller 200, the driving motor controller 200 controls to unlock the driving motor 151 of the driver's door (S530). ). The driving motor controller 200 checks whether the driver's door unlocking driving signal is continuously received for a predetermined time (for example, 3 seconds) after the driving control of the driving motor 151 of the driver's door is unlocked (S530). If the driver's door unlocking driving signal is continuously received for more than 3 seconds, the driver's door is unlocked by controlling the subordinate door of the driver's door, that is, the driver's door unlocking driving motor 152 (S540) (S550). If the driver's door unlocking driving signal continues to be received even after more than twice the set time (eg, 6 seconds), the driving motor control unit 200 drives the unlocking of the subordinate door of the front passenger's door, that is, the rear passenger's door. Drive control of the motor 153 unlocks the door behind the passenger seat. Similarly, if the driver's door unlocking driving signal is continuously received even more than three times the set time (eg, 9 seconds), the driving motor control unit 200 drives the unlocking of the fourth-order door, that is, the door behind the driver's seat. Drive control of the motor 154 unlocks the door behind the driver's seat. As described above, it will be apparent to those skilled in the art that a driver or a user must continuously operate the driver's door unlocking switch 151 in order to continuously generate the driver's door unlocking driving signal. On the other hand, after the drive motor control unit 200 unlocks driving control of the driving motor 151 of the driver's door, the driver's door unlocking drive signal is not continuously received for a predetermined time (for example, 3 seconds). If it is confirmed (S560), the drive motor control unit 200 does not control the unlocking drive motor of the other door.

In the above-described embodiment, when the driver's door unlocking switch 151 is pressed for 3 seconds, 6 seconds, or 9 seconds or more, the subordinate priority unlocking switches 152, 153, and 154 are operated, respectively. The locking switches 152, 153, and 154 may all be designed to operate. In addition, when another door unlocking switch is pressed instead of the driver's door unlocking switch 151, the priority door unlocking switch may be designed to operate instead of the subordinate.

On the other hand, the door locking and unlocking control method of the vehicle according to another embodiment of the present invention, as shown in Figure 6, the step of detecting whether the card key or the fob key 50 has approached (S600); An unlocking driving step (S610) of selectively driving control of the door unlocking driving motor; And a locking driving step (S620) of controlling all the door locking driving motors at once. Here, the approach detection step (S600) of the card key or the fob key 50 carried by the user is performed by the wireless sensing access sensor 155 which detects a radio signal from the card key or the fob key provided on the handle side of the door. Detect access of card key or fob key.

In the unlocking driving step (S610), the door button switch unit 170 determines whether there is an unlocking signal (S612), and if there is an unlocking driving signal, only the unlocking driving motor of the driver's door is controlled separately and the remaining operation is performed. It is determined whether the driving control of the door is unlocked at the same time (S614). If "NO" in step S614, the step of controlling the unlocking driving of all the doors of the vehicle is individually performed (S618). If yes, only the driver unlocking driving motor is separately driven and the other unlocking driving motors are driven at a time (S616).

The locking driving step (S620) includes determining whether there is a locking signal, and if there is a locking signal (S222), driving all of the locking driving motors at once (S224). As described above, the locking driving step (S620) generates a signal for locking driving all of the door driving motors by the user's operation or when the user carrying the card key or the fob key moves away from the door. It is possible to generate a signal for locking driving all the drive motors.

In the present invention, the drive motors 151-154 operate as unlocking drive motors and locking drive motors, respectively, and operate as a locking drive motor when operated in a clockwise direction and as unlocking drive motors when operated in a counterclockwise direction. It can be understood to work. That is, the door unlocking driving motor and the locking driving motor which are dealt with in the present invention, as will be apparent to those skilled in the art, do not exist separately, and one motor has a different role depending on the direction of operation. The representation of the drive motor and the locking drive motor as present separately is for convenience of explanation only.

In the present invention, the door button switch unit 170 may be designed to have at least two or more unlocking switches for selectively driving the unlocking driving motor, but the unlocking switches may be formed as a touch switch for touch action. It may be. The door button switch unit may be installed both inside and outside the door, and when installed outside the door, it is apparent that the door is waterproofed.

In addition, in the present invention, when the unlocking signal is transmitted from the door button switch unit 170 as described above, the driving motor control unit 200 receives the unlocking signal to drive control so that only the corresponding driving motor of the door is unlocked. Since the driving motor control unit 200 can easily implement the technology to control the driving motor by receiving a radio signal through a technique well known in the art, a detailed description thereof will be omitted for the sake of clarity. do.

Up to now, preferred embodiments of the door locking and unlocking control apparatus and method of the vehicle have been described. In the description of the embodiments, the case where there are four or two doors has been described as an example, but the present invention is not limited thereto. It will be apparent to those skilled in the art that the present invention can be applied in consideration of not only a door but also a trunk, and can be easily applied to a vehicle having four or more doors.
