BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic control system for a vehicle, and more particularly, to an automatic control key system in which a comprehensive control operation related to method management and initial operation of a vehicle can be operated under control of a system microprocessor related to button key operation. .

As the use of vehicles becomes more common, theft of vehicles and the seizure of internal electronic devices are intensifying.

Therefore, the door keylock structure of the vehicle door, which is an initial gateway through which a third party can enter the vehicle, can be specially designed to prevent theft of the vehicle, or the door keylock structure can be easily released by the third party. While technologies that are not being used are being transferred, a second key gate of a third party, a start key lock structure, is also being provided with specially designed technologies.

Also known is a technique for warming up engine driving such as winter by starting a start condition related to vehicle management and initial operation from a remote location.

In this situation, the door keylock structure is advanced from the mechanical type, and the electronic unlocking formula and the password input unlocking formula by the button are displayed, and they are configured to accomplish the door opening and unlocking by mounting a simple password logic circuit. .

In addition, the latter start-up key lock structure is not practical because it should be a method function for a third party, but may have an advantage in that it performs a secondary defense.

For example, a person who intrudes into the interior of a vehicle cuts the wire directly without dismantling the start key lock structure, and finds an electric line related to the start and performs the start. For those who do not know may have a minimum method function.

In addition, these start key lock structures or door key lock structures are usually provided with an alarm function associated with the operation of a third party.

However, such conventional door key lock devices and start key lock devices are limited in their use because they are designed to focus on their original primitive purpose, such as opening and closing doors or opening and closing electric lines required for starting. Many, at least lacking in expectation of perfect method functionality.

For example, these key lock devices are in an independent form, whether they are installed only on the door or on the ignition key, so that the first key, the key lock device, is unlocked by a third party. The devices could also be easily unlocked, making it difficult to complete the method's functioning, increasing the device volume and size from independent operation, or difficult to rule out the cause of price increases in the overall use of these devices.

It was also disadvantageous in method performance because they were not made up of mutual organic connections.

In addition, the key lock device in the vehicle as described above is inconvenient to use the individual power on and off keys in order to start the vehicle or operate the electric equipment (indoor lights, air conditioners, acoustic equipment, etc.) in the vehicle. It was disadvantageous in terms of convenience because it could not expect functions such as reservation start and warm up operation.

In addition, the series of operations and functions related to the initial operation of the vehicle are independent, while the control functions such as automatic flashing lights at the time of stopping the headlights during the operation of the night vehicle are also operated as separate facilities. It was difficult to avoid such disadvantageous problems.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic control key system for a vehicle that enables reservation starting in addition to improving the problems of the prior art as described above.

It is still another object of the present invention to provide the door keylock means, which is the first secondary door of the third party's in-vehicle entry, in order to enhance the security function of the vehicle. The second key of the electronic control associated with the start-up of the keylock device is to provide an automatic control key system of the vehicle, in which the start-up keylock means are driven together with the information function to enhance the security function.

Still another object of the present invention is to provide an automatic control key system for a vehicle capable of comprehensively controlling a series of working conditions related to initial operation and management in a vehicle by a button-type key operation in addition to the reservation start and crime prevention functions.

In particular, the present invention relates to a main controller incorporating a one-chip microprocessor and to a series of operations of the vehicle by means of the controller, such as one-touch engine start, reservation start, automatic flashing of the headlight, theft alarm to generate an alarm sound for external shock, and a password.

The present invention configured as described above has the following effects and effects.

According to the present invention, the data input by the door key input unit 2 and the main key input unit 100 of the main controller 1 and the detection signal input from each sensor of the sensor input unit 3 are attached to the outside of the door. After recognizing the processor 11, the system is driven (in this case, it is possible to control separately with each function control device added to an existing vehicle), but if the user wants to open the door from the outside, the main controller 1 When the user inputs the password, which is set in advance by the user, in the door key input unit 2, the key switch is pressed and the current flowing to the buzzer 21 for checking the press is cut off so that a momentary alarm sounds and at the same time, it is connected to the data line. It is encoded through the I / O interface 42 of the control box 4 and applied to the microprocessor 11 of the main controller 1 so that the main controller can be input to the input. And the corresponding output port is controlled by the microprocessor 11 to release the door key lock part (MOTOR R) of the vehicle according to the I / O interface 41 of the control box 4. Decode and select the output value at the current output and this current output is amplified to a predetermined ratio enough to drive the relay while passing through the current amplifier 43 to drive the corresponding relay (RY ₁ ) (RY ₂ ) The door is opened because the door key lock part (MOTOR L) of the vehicle is released by the motor. At this time, if the on / lock switch (SW ₁₁ ) is pressed before the password is pressed, the lamps 22 and 23 light up. Convenient to use at night.

In the above-described password setting process in the main controller 1, the user first selects a number of 1 digit or more and 6 digits or less and then presses the password setting switch PASS of the main key input unit 100, and the selection data is displayed on the display interface ( The signal encoded through 14 is applied to the microprocessor 11 to prepare to store data which is input to the internal RAM in the future, and simultaneously to the display interface 14 via the digital buffer 16. It is applied to the associated display unit 19 and is ready to display the currently input key data. Then, when the existing password is input, the display unit 19 issues a command to input data to be stored in the future and accordingly When data to be memorized is inputted, the input key value is displayed and the microprocessor 11 It is stored in RAM.

For example, if the previously entered password is "1234" and the new password to be remembered is "1988", press the password setting switch (PASS) on the main key input unit 100 of the main controller 1 and the existing password " If 1234 "is inputted, the display unit 19 displays a letter for entering a new password of the phrase“ In ”. If the new password“ 1988 ”is pressed, the display unit 19 displays the data and simultaneously displays the data. Encoded through 14 and applied to the microprocessor 11, a new password of "1988" is stored in the built-in RAM of the microprocessor 11.

As described above, when the engine is to be started after the door is opened, the primary key switch 100 of the main controller 1 is pressed in order to press the primary power switch ACC and the start switch START. The value is encoded into the data line via the display interface 14 and applied to the microprocessor 11, whereby the microprocessor 11 again outputs its decoding output to perform the operation corresponding to the key data. ₂₀ -P ₂₇ ) to drive the I / O interface 41 of the control box 4 so that the current output at the corresponding output port of the I / O interface 41 passes through the current amplifier 43. While being amplified enough to drive the relay, the relay RY ₇ and RY ₁₀ are driven to operate the ignition coil unit ICC and the starting motor unit SM, thereby starting the engine.

On the other hand, when the engine is to be shut off, press the start switch (START) and the primary power switch (ACC) of the main key input unit 100 in order in the interior of the vehicle in accordance with the above principle of the relay (RY ₇ ) (RY ₁₀ ) When the power is cut off and the start is cut off, when the on / off switch SW ₁₁ of the door key input unit 2 is closed after closing the door of the car, the relay RY ₁ (RY ₂ ) above. The power of (RY ₇ ) is cut off and the vehicle starts to shut off and lock the door.

In the present invention, a reservation start by the self timer function of the microprocessor 11 and the watchdog function of the multivibrator 12 may be performed. After setting the timer of the microprocessor 11 according to the current time in advance, the reservation time is input and the count time of the timer is monitored by the multivibrator 12, that is, the watchdog, and the microprocessor 11 reaches the reservation time. By recognizing the start command by itself, the ignition coil unit IGB and the starting motor unit SM are operated in the same manner as the engine start operation.

For example, if the time to start the scheduled start is 6:30 am, press the timer switch (TIMER), the current time key switch and the primary power switch (ACC) to set the current time. Pressing the start / release switch (MEMO / P) of the key input unit 100, the " 630 " key switch, and the primary power switch (ACC) in sequence, the microprocessor 11 receives the data applied through the display interface 14. A separate location dock is stored in its own RAM to monitor the count time of its own timer, while the user is set via the display unit 19 connected to the display interface 14 and the digital buffer 16. You will see the time.

In this way, when the timer of the microprocessor 11 reaches the reservation time by monitoring the position dock, the position dock sends an interrupt signal to the microprocessor 11 so that the microprocessor 11 recognizes the start command and the control box. (4) operates the ignition coil unit (IGC) and the starting motor unit (SM) of the vehicle through the I / O interface 41, and after a certain time in the state of starting up, that is, after a certain time of warm-up time passes The multivibrator 12 operates to change the output data of the microprocessor 11 to output the relay driving current so that power to the air conditioner and the heating wire can be applied, and after that, a predetermined time elapses. If there is no other control operation by the user, the start-up is cut off in the same manner as when the start-off switch is pressed.

In the present invention, a function for automatically flashing the headlamp is added, which is when the light switch LIGHT of the main key input unit 100 is pressed once, the small light unit LIGHT 1 is activated, and when pressed twice, the mon light unit LIGHT is pressed. 1) The headlight unit LIGHT 2 is fixedly operated, and when pressed three times, the small light unit LIGHT 1 is fixed. The headlight unit LIGHT 2 is automatically turned on. The microprocessor 11 is driven by the detection signal input to the RPM sensing unit 45 and the sensor circuit unit 46 of the control box 4 from the ignition coil sensor 32 and the side brake sensor 35 of FIG. Automatic flashing is enabled by recognizing the driving / stopping status.

When the automatic control system of the present invention is to be temporarily stopped and the existing mechanical key is to be used, the reservation start / release switch (MEMO / P) of the main key input unit 100 is pressed and the password is sequentially pressed. This is possible by stopping all functions.

On the other hand, the sensor input unit 3 of the present invention includes a shock sensor 31 for detecting an impact from the outside in a plurality of places of the vehicle body, a remote control sensor 33 which is a remote control signal receiving device for remote control, and a method using a password. An indoor lamp sensor 34 is provided to detect the case of entering the room by other methods, so that the signal detected through the sensor input unit 3 is shaped and amplified by the sensor circuit unit 46 of the control box 4. By recognizing the detection signal from the microprocessor 11 through the I / O interface 42, the microprocessor 11 drives the alarm unit AUX1 attached to a predetermined position of the vehicle to prevent theft and other Safety accidents can be prevented in advance.

The present invention, which is driven in the above manner, is limited in its function by a dip switch 13 fixedly attached to the rear of the main controller 1. Each terminal of the dip switch 13 has an alarm for preventing theft. Randomly set the number of driving times (e.g. 3 times, 4 times, 8 times, 12 times) or set / cancel the alarm sound that sounds when a key switch is pressed in the door key input unit (2), and reserves the time around the scheduled start-up It is possible to set an alarm ringing to indicate that the alarm is started, or to set a warm-up time at a scheduled start-up (for example, 10 minutes or 20 minutes) or add an auxiliary function to disable the reservation function.

Therefore, the present invention can be free from the inconvenience of theft, loss, unauthorized copying, etc. caused by the possession of the car key because all the control operation of the car is possible by one-touch by the main controller, and the password can be freely changed by others. It is very useful to prevent the control easily, the reservation function and the warm-up setting is convenient for the winter boarding, and the automatic lighting device is convenient for the night driving.
