1 is a schematic configuration diagram of a vehicle remote control system in which a wireless communication terminal and a vehicle control apparatus control a vehicle by voice or text communication according to the present invention.

The vehicle remote control system according to the present invention enables a wireless communication module installed in a vehicle control apparatus provided in a vehicle and a normal wireless communication terminal to communicate through a wireless communication network to remotely control the vehicle by voice or text communication. .

As shown in FIG. 1, a general mobile phone capable of wireless communication through various wireless communication networks, that is, a wireless communication terminal 110, a wireless communication network 120, an satellite 130, and a vehicle control device are included. The device includes a wireless communication module 160, a GPS receiver 170, a vehicle controller 140, a microphone 161, a keypad 143, a display 141, a control command recognizer 144, and a TTS generator 162. And an electronic control unit 150 for controlling the vehicle driving apparatus.

In particular, the electronic control unit 150 is provided with a sensor unit 151 made of sensors for detecting the opening and closing of the door, the current state of the engine oil, fuel, the temperature of the vehicle, and the like, the door lock device 152 or the starting device 153 And control the driving of various vehicle driving apparatuses such as the air conditioning system 145.

The wireless communication terminal 110 refers to all terminals capable of wireless communication, including a general mobile phone, and is not limited to a wireless communication terminal having a specific telephone number carried by an individual.

The wireless communication module 160 mounted on a vehicle and having a unique telephone number capable of wireless communication such as a conventional mobile phone is a driver, that is, a user's wireless communication terminal 110 and a vehicle, more specifically, a vehicle control unit 140. Real-time connection to enable communication of voice or text data, which is a control command for remote control of the vehicle.

The vehicle control unit 140 is received from the user's wireless communication terminal 110 through the wireless communication module 160, the user's voice or text and voice or text database 142 recognized by the control command recognition unit 144 Compares and analyzes the registered voice or text to recognize the control command for driving the vehicle driving device, and then controls the driving of the vehicle driving device according to the result or from the sensors of the sensor unit 151 according to the user's request. Controls an operation for identifying the vehicle position information obtained from the satellite 130 through the collected vehicle state information or the GPS receiver 170 and transmitting it to the wireless communication terminal 110.

The voice or text database 142 embedded in the vehicle controller 140 has a voice or text for controlling the driving of a vehicle driving device such as a door lock device 152, a starter 153, an air conditioning system 145, or the like. The voice or text registered in the voice or text database 142 as a registered memory is input through the microphone 161 and the keypad 143 connected to the wireless communication terminal 110 or the vehicle control unit 140 to control the vehicle. It can be registered with the object and control method.

In addition, the password for authentication of the user is registered in the voice or text database 142, which also requires security, so that the user can register by operating the wireless communication terminal 110 or the keypad 143. When registered by the keypad 143 connected to the vehicle control unit 140 is transmitted to the wireless communication terminal 110 through the wireless communication module 160 is stored in the wireless communication terminal 110.

Here, when the voice or text input through the wireless communication terminal 110 or the microphone 161 and the keypad 143 is registered as voice or text for driving control of the vehicle control target, the vehicle controller 140 is to register. The driving state of the vehicle controlled by voice or text is transmitted to the user through the wireless communication terminal 110 or the display unit 141 so that the user can accurately register necessary information.

That is, the user requests voice or text input information for controlling the vehicle by operating an input means such as a keypad of the wireless communication terminal 110 or the keypad 143 connected to the vehicle controller 140, and the vehicle controller 140 According to the user's request, the user may be provided with information on a voice or text for controlling the vehicle, which the user may register, so that the user may register a voice or text for the desired vehicle control.

In the case where the vehicle control is performed as the text, the vehicle can be controlled by converting the voice into the text. That is, the TTS generation unit 162 connected to the vehicle control unit 140 converts the voice inputted through the microphone 161 or transmitted from the wireless communication terminal 110 into a text to control a command corresponding to the converted text. It is also possible to register.

The control command registered in the voice or text database 142 in the vehicle control unit 140 is, for example, 'open door', 'close door', 'walk start', 'start off', 'turn on air conditioner', 'air conditioner' Off, "or the like.

On the other hand, when registered as a voice, the control command recognition unit 144 is further provided with a voice recognition device or program, the voice of the user or one or more other non-user specified by the user as a voice for controlling the driving of the vehicle control target The user can be registered, and distinguishing a legitimate user by speech recognition is a technique well known to those skilled in the art, and the present invention is not limited thereto.

2 is a flowchart illustrating a process of remotely controlling a vehicle by voice or text using a wireless communication terminal according to the present invention.

First, when the vehicle remote control system is initially installed or initialized, or when the control command is reset at the request of the user, a voice or text for remotely controlling the vehicle driving apparatus provided in the vehicle must be registered in the voice or text database ( S210).

The voice or text registered in the voice or text database in step S210 is then used to compare with the control command of the voice or text transmitted from the wireless communication terminal by the user.

After a voice or text is registered to remotely control a vehicle driving device provided in the vehicle, the user drives a wireless communication terminal to drive a program to remotely control the vehicle and transmits a control command for the vehicle by voice or text. At this time (S220), the control command is encoded using an encryption key by the method described below.

The reason for encoding the control command using the encryption key as described above is described in detail below, and thus will be omitted here.

When the control command of the voice or character encoded control command using the encryption key is transmitted from the wireless communication terminal, the control command of the encoded voice or character is received through the wireless communication module included in the vehicle control apparatus and decoded by the decryption unit. In operation S230, the decoding process and the operation of the decoding unit are described in detail below, and thus will be omitted.

First, the control command of the voice or text decoded by the decoder determines whether a command for terminating the vehicle remote control is included (S240).

The command for terminating the remote control of the vehicle may be, for example, a word of 'control termination', but is not limited thereto. A word having a meaning capable of terminating control of the vehicle is sufficient.

As a result of the check in step S240, if the command to end the vehicle remote control is terminated.

However, if it is determined in step S240 that the command for terminating the remote control of the vehicle is not included, the decoded voice or text is matched by comparing the vehicle control registered in the voice or text database with the voice or text in step S210. Check whether there is (S250).

As a result of the check in step S250, if there is no match, although not shown in the flow chart of FIG. 2, it generates and transmits information indicating that there is no match with the wireless communication terminal, and the wireless communication terminal is provided with the wireless communication terminal. It is possible to display on a display part (not shown).

If it is determined in step S250 that there is a match, the vehicle controller generates a control signal for performing a control command for controlling the vehicle driving apparatus provided in the vehicle according to the matched item and outputs it to the electronic control unit (S260). .

The electronic control unit receives the control signal from the vehicle control unit to generate a driving signal suitable for the vehicle driving apparatus and outputs the driving signal to each vehicle driving apparatus (S270).

Thereafter, the process returns to step S220 to check whether an additional control command is transmitted from the wireless communication terminal.

Meanwhile, in the above embodiment, it is illustrated that the driving of the vehicle remote control system can be terminated only by the control termination command, but is not limited thereto.

That is, as another example of terminating driving of the vehicle remote control system, a timer may be further installed to terminate driving of the vehicle remote control system when the control command is not received during the time interval determined by the timer. Since it is not limited, a detailed description of the operation will be omitted.

3 is a schematic configuration diagram of an apparatus for encoding and decoding a command for remotely controlling a vehicle according to the present invention.

In the vehicle remote control system according to the present invention, the control command is encoded and transmitted using an encryption key value. The reason is that if it is not an encrypted control command, an unauthorized user can arbitrarily access and control the vehicle remote control system of the vehicle, and therefore there is a risk of theft and damage of the vehicle. Connect to the control system.

Meanwhile, in the present invention, in order to transmit and receive a control command by accessing the vehicle remote control system, after confirming whether the user is authorized at the first connection as in the prior art, and confirming that the user is authorized, the user who is separately approved for the subsequent control command Unlike not checking whether a command is sent from the terminal, a control command sent every time is encrypted, thereby providing a higher level of security than that proposed in the prior art.

FIG. 3A is a schematic block diagram of an apparatus for encoding a control command using an encryption key value in the wireless communication terminal 310. FIG. 3B is a control coded using an encryption key value in the vehicle control apparatus 320. FIG. It is a schematic block diagram of the apparatus for decoding a command.

First, referring to FIG. 3A, when a control command of voice or text is input through the control command input unit 315, the input control command is converted into the encrypted command 317 through the portable encoder 316. After it is transmitted to the vehicle control device 320 through the transmitter 318.

The portable encoder 316 according to the present invention is characterized in that it is sufficient that an encoder capable of outputting a digital value is sufficient to use a code value in which a symbol value used to convert data input from the encoder into a digital value is encrypted. .

An example of the portable encoder 316 is a digital modulator, but is not limited thereto.

As an example of the portable coder 316, a pulse coded modulation (PCM) modulator is used. A PCM modulator is a pulse string (symbol value) having a predetermined period for quantizing a signal whether an input signal is an analog signal or a digital signal. It is possible to use a clock cycle, and if it is possible to encrypt the pulse train, it is possible to encrypt the input signal.

According to this, it can be seen that if the symbol value of the modulator can be encrypted, it is possible to encrypt the control command. In the present invention, the symbol value, that is, the encryption key value 314, is fixed to the fixed variable and the variable variable stored in the storage unit. The variable input unit 311 and the portable variable variable input unit 312 are respectively input and generated by the portable random function generator 313 is characterized.

The fixed variable may be, for example, a phone number assigned to a wireless communication terminal, and the variable variable may be a password input and set by a user. The phone number is not changed unless the wireless communication terminal 310 is changed. Therefore, it was taken as a fixed variable, and the password can be changed as needed, so it is set as a variable variable, but is not limited thereto.

For example, an ESN (Electronic Serial Number) is allocated to a wireless communication terminal and can be used as a fixed variable.

Since the random function generators 313 and 323 are well known technologies, detailed descriptions thereof will be omitted.

However, in the present invention, it should be noted that the random function generators 313 and 323 provided in the wireless communication terminal 310 and the vehicle control apparatus 320 are the same.

Although not shown in the random function generators 313 and 323 of the wireless communication terminal 310 and the vehicle control device 320, the same program is implemented to perform a random function that generates the same random number for the same input value.

On the other hand, since the normal random function generates different random numbers even with the same input value at different times, the portable random function generator 313 and the vehicle random function generator 323 generate different encryption key values. In order to solve the present invention, even if the same input value is input at different times, the parameters for the time of the random function are fixed to generate the same random number or the time value is transmitted when the control command is transmitted from the wireless communication terminal 110. Transmits and receives the control command and the time value at the receiving unit 328 of the vehicle control device 320 and inputs the received time value to the random function program so that the random function operates at the same time. It is possible to get

As described above, the wireless communication terminal 310 of FIG. 3A uses a user's telephone number as a fixed variable, and the password stored in the vehicle control device 320 and the wireless communication terminal 310 is set in advance as a variable variable. When outputting a result value corresponding to an encryption key value as an input value of the portable random function generator, the portable encoder 316 encrypts the control command by using the result value as an encoding parameter (for example, a symbol value or a pulse string). Encode by.

The control command 317 encoded as the encryption key value as described above is transmitted to the wireless communication module provided in the vehicle control apparatus 320 through the transmitter 318.

The operation after processing the control command encoded with the received encryption key value will be described in detail with reference to FIG. 3B.

3B is a device for decoding the control command encoded by the encryption key value in the vehicle control device 320.

The receiver 328 receives a control command encoded with an encryption key value transmitted from the wireless terminal 310, and the received encoded control command 325 is input to the vehicle decryption unit 326.

The vehicle decoder 326 decodes the encoded data through the inverse process of the portable encoder 316 and outputs a control command 327 for voice or text.

Meanwhile, since the control command 317 encoded as described above is encrypted by the encryption key value, the control command 317 is not decrypted unless the correct encryption key value is input in the process of decoding by the vehicle decryption unit 326. In the present invention, the wireless communication terminal 310 Since the encryption key value generated by the random function generator 313 having the same random function used in the above) can be obtained, it can be decrypted normally.

To this end, the vehicle random function generator 326 included in the vehicle control device 320 may be configured through a vehicle fixed variable input unit 321 and a vehicle variable variable input unit 322 from a storage unit connected to the vehicle control unit illustrated in FIG. 2. Generates an encryption key value 323 by receiving the fixed variable and the variable variable, and outputs it to the vehicle decryption unit 326. The output encryption key value 323 is input to the vehicle decryption unit 326 to encode the encoded control command 325. It is used to decode.

Accordingly, it is possible for the vehicle decryption unit 326 to use the same encryption key value 324 as the encryption key value 314 used in the portable encoding unit 316 of the wireless communication terminal 310, and thus the vehicle transmitted from the authorized user. Since only the control command of the vehicle is controlled so that the vehicle can be safely controlled.

4 is a process of encoding a control command using an encryption key value in a wireless communication terminal according to the present invention.

First, when the vehicle control command program is executed in the wireless communication terminal, the user sets a variable by inputting a password (S420).

Meanwhile, in step S420, the password is input when the vehicle control command program is executed, but when the vehicle remote control system is first installed or initialized, or when the control command is reset at the user's request, the password is input and stored in the vehicle control device. It may also be transmitted to and stored in a wireless communication terminal.

It is set as a password by the above process and can be used continuously while the control command program is being driven as an input value of a random function of the portable random function generator as a variable variable.

Thereafter, a vehicle control command is input by a user from a speaker or a keypad (S430), and at the same time, the portable random function generator generates an encryption key value using a predetermined fixed variable (phone number or ESN) and an input password that is a variable variable. (S440).

Thereafter, the portable encoder encodes a control command of a voice or a character by using the encryption key value and encrypts it (S450), and transmits it to the vehicle controller through the transmitter (S460).

5 is a process of decoding a control command in a vehicle control apparatus according to the present invention.

The vehicle control apparatus installed in the vehicle while the vehicle remote control system is being driven continuously monitors the receiver to receive the encoded control command from the wireless communication terminal (S510).

When the encoded control command is received or when a fixed variable (telephone number or ESN of a wireless communication terminal) and a variable variable password, which are input and stored in advance, are input values, the vehicle random function generator provided in the vehicle control apparatus includes an encryption key value. To generate and input to the vehicle decoding unit (S520).

The vehicle decryption unit decodes the control command encoded by the input encryption key value. When the vehicle decryption unit is different from the encryption key value included in the received encoded control command, the decoder cannot normally decode the received encryption key value of the received control command. It is recognized that the encryption key is different from the, and if the user is in the vehicle, the display unit provided in the vehicle control device indicates that the unauthorized control command has been received, if the user is not in the vehicle wireless communication terminal Data indicating that an unauthorized control command has been received as a letter may be transmitted to be displayed on the display unit of the wireless communication terminal.

Meanwhile, a normal coded control command may be decoded by the vehicle decoder, and the decoded control command is a control command for driving the vehicle driving apparatus provided in the vehicle in the form of voice or text. Since it is described in detail in the description about 2 it will be omitted.
