In addition, when the door lock is executed while the ignition key is left inside the vehicle inadvertently, the driver provides convenience to reopening the door to provide reliability in driving.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a method for controlling a peripheral device of a vehicle, the method comprising: determining whether a key selection signal for use of a peripheral device is detected from a key input means in a state where an ignition key is separated;

If a key signal is detected, the method includes driving the peripheral device through the driving means according to the detected key signal.

In addition, when the input of the ten key for using the peripheral device is detected, the timer unit is driven to count the elapsed predetermined time, and determining whether the detected key signal continues continuously within the counting time,

It characterized in that it comprises a process of operating the peripheral device through.

In addition, the present invention is the key input means for outputting the peripheral device drive selection signal is switched by the contact point according to the driver's selection;

A / D conversion means for converting the analog signal output from the key input means into a digital signal;

Memory means for storing program data for executing driving of each peripheral device in a predetermined address area, respectively;

Analyzes the input key signal and compares it with the program data set in the memory means, and controls the overall operation for driving the selected peripheral device, and continuous key signal input is not detected within a predetermined time after the initial key input is detected. Control means for initializing an input of a key signal,

And an actuator which is driven at a predetermined angle in a predetermined direction according to the signal of the control means.

EXAMPLE

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

As can be seen in Figure 1, the peripheral device control apparatus using a password according to the present invention, the key input unit 10, the A / D converter 20, the control unit 30, the memory unit 40 and the actuator ( The key input unit 10 is composed of a ten key (0-9) and a predetermined function key at predetermined positions inside and outside the vehicle, and the contact point is switched according to the operator's selection to select a peripheral device drive. Output the signal.

The A / D converter 20 converts an analog signal applied from the key input unit 10 into a digital signal that can be read by the controller 30 and outputs the digital signal.

The memory unit 40 stores program data for driving each peripheral device included in the vehicle in a predetermined address area, respectively.

The controller 30 analyzes the input key signal, compares it with the program data set in the memory unit 40, and controls the overall operation for driving the selected peripheral device. The controller 30 continuously operates within a predetermined time set after the initial key input is detected. If the input of the key signal is not detected, the input of the key signal is initialized to prevent malfunction and theft of the vehicle.

The actuator 50 is a means for driving each peripheral device and is driven at a predetermined angle in a predetermined direction according to a signal applied from the controller 30.

The operation of the present invention having the function as described above will be described with reference to FIG.

When the ignition key of the vehicle to which the means of the present invention is mounted is separated from the key holder (step 101), the password of the peripheral device to be driven through the turn key of the key input unit 10 is driven to drive any peripheral device. When input, the key input unit 10 outputs a signal corresponding to the selected digit and applies it to the A / D converter 20.

When the A / D converter 20 converts an analog signal applied from the key input unit 10 into a digital signal and applies it to the control unit 30, the control unit 30 drives the counter means in response to the detection of the selection signal. Counting proceeds for a predetermined time (step 102, step 103).

At this time, the controller 30 detects whether the input of the detected key signal is continuously input within a predetermined time set by the counter means (step 104), and continuously inputs the key signal for driving the peripheral device within the set time. If this is not detected, the input selection signal is initialized to drive the peripheral device (step 108), and if the input of a continuous key signal is detected within a predetermined time period, the selection signal applied is analyzed (step 105).

Thereafter, the detected selection signal is detected through the table set in the memory unit 40 (step 106), and then the door or the door selected to be driven by applying a predetermined signal to the actuator 50 side. Drive peripherals such as a trunk or burglar alarm.
