Abstract
In the existing vehicle structure, a smart key system interworking with an electronic authentication control device through minimal structural changes and enabling keyless entry and keyless start using a unidirectional RF portable terminal and a control method thereof are presented. The one-way RF portable terminal and the electronic authentication control device authenticate and open the door if they match the pre-stored authentication signal. In addition, the steering lock is released, and driving is possible according to the operation of the start switch.
Description
The present invention relates to a smart key system and a control method thereof, and more particularly, to a smart key capable of keyless entry and keyless start without the need for a mechanical start key in conjunction with an electronic authentication device and a control method thereof.
Cars are now becoming a necessity of life as the standard of living increases and the supply of cars increases. Accordingly, research on a variety of technologies, such as a car, an anti-theft device of a vehicle and opening and starting the door of the vehicle, is steadily progressing. For example, a keyless entry method and a keyless start method are provided. ).
The keyless entry method is a method in which the door lock is released by the driver without a separate mechanical ignition key. When the driver pushes a button of the RF terminal, the door is automatically unlocked when the key and the electronic authentication device inside the vehicle transmit and receive data with each other.
Pressing the unlock button causes the remote starter to send a code with the instruction to open the car door. If the receiver, activated simultaneously with the unlock button, receives the code as expected, the vehicle moves according to the instructions, such as unlocking and opening the door, otherwise it will not respond. This keyless entry method is in the spotlight of consumers because it is useful for its convenience and prevention of theft.
In such a keyless entry method, the driver is required to carry a key used in a vehicle at all times. In other words, if the driver does not have the key, it is impossible to unlock the door or open the door.
This inconvenience is the same in the keyless start method. The keyless start method refers to a method in which a driver can operate a vehicle by starting, operating and stopping the engine if the driver is electronically authenticated without inserting or manipulating a separate mechanical key. If it is certified by the user, it is convenient to start, operate and stop the engine by pressing the button or by hand.
That is, even in the keyless start method, the driver must always carry a mechanical key that can be authenticated for mechanical authentication.
In order to solve such inconvenience, there is an active research to implement a keyless entry and keyless start method of a vehicle by using a unidirectional RF portable terminal. There is a growing tendency to incorporate smart key systems that can drive vehicles without mechanical keys.
Keyless start and keyless entry are implemented together, and there is little research on an integrated system that enables the vehicle to open / lock the door, start the engine, and operate the vehicle without manipulating the mechanical ignition key.
Accordingly, the present invention has been made to solve the above problems, and provides a smart key system and a control method capable of automatically keyless entry and keyless start without the need for a mechanical start key in conjunction with an electronic authentication control device. Its purpose is to.
Another object of the present invention is to provide a safe and reliable smart key system and a control method thereof without fear of theft of the vehicle.
In addition, an object of the present invention is to provide a smart key system and a control method thereof that can be easily mounted after the interworking with the electronic authentication system through a minimum structural change in the existing vehicle structure.
According to a preferred embodiment of the present invention for achieving the above object of the present invention, the present invention discloses a unidirectional RF portable terminal, an electronic authentication control device and a steering lock device for locking or unlocking the steering in communication with the terminal do. Holders of certified terminals to enable keyless entry and keyless start will be able to open the door, unlock the steering lock and start easily, while ensuring high security.
Using the one-way RF portable terminal, the electronic authentication control device inside the vehicle communicates to open the door for the authenticated user. When the start switch is operated in the ACC mode, when a signal for releasing the steering lock is transmitted, the signal is received to release the steering lock. The power is supplied to the ACC mode to switch to the ACC mode, and the ON mode and the start are applied according to the operation of the start switch. Therefore, keyless entry and keyless start are possible without the need for a start key in conjunction with the electronic authentication device.
As described above, according to the present invention, the keyless entry and the keyless start can be performed without the need for a mechanical start key in conjunction with the electronic authentication device.
In addition, the present invention has the effect of easy post-installation because it is linked with the electronic authentication system through a minimum structural change in the existing vehicle structure.
In addition, the present invention is safe and reliable without theft of the vehicle, it is possible to change the existing mechanical steering lock device to interoperate with the electronic authentication device in a relatively simple way, it is useful to prevent theft of the vehicle to improve the security It has an effect.
As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed without departing from the spirit and scope of the invention described in the claims below I can understand that you can.
The smart key system referred to herein is a concept encompassing the aforementioned keyless entry and keyless start, which collectively refers to a driving authority authentication system including a user's door opening to starting and driving. .
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments.

The electronic
To use this smart key system, you must first perform a user authentication procedure. When using for the first time, or when the owner of the vehicle, or the owner of the one-way RF portable terminal is changed, such a fast and secure authentication method is required.
As shown in FIG. 2, when the button of the unidirectional RF portable terminal is pushed, the door lock is released through electronic authentication. Then, the unidirectional RF portable terminal and the holder of the terminal can open the door using the door handle and ride in the vehicle interior. If there is a start switch inside the vehicle, and the mobile communication terminal holder moves the start switch to the ACC mode (S11), the electronic authentication controller receives this signal, and it is preferable to include a procedure for confirming the link authentication of the Bluetooth ( S12).
When the authentication is confirmed, a signal for releasing the steering lock is generated (S13), and the steering lock is released (S14). In this case, if the steering lock is not released, the steering release signal may be repeatedly supplied to the actuator until the steering lock is continuously released again. When the steering lock is released, electricity is supplied to the ACC mode to the ACC mode (S15), and the ON mode (S16) or the start may be applied by the user's start switch operation (S17).
The process of stopping and starting the vehicle is generally the reverse. When the mobile communication terminal holder moves out of the interior of the vehicle and goes out of the short range communication area such as Bluetooth, the door lock of the vehicle is locked.
Hereinafter, the detailed structure and operation of the steering lock device provided with the actuator will be described.
