Abstract

본 발명은 자동차의 시동장치에 관한 것으로서, 종래에는 자동차의 키를 이용하여 자동차의 시동을 걸었기 때문에 자동차의 키를 분실했거나 자동차의 키가 어디에 있는지 생각 나지 않을때에는 자동차의 시동을 걸 수 없으므로 키를 항상 소지하고 다녀야 하는 부담이 발생됨과 더불어 제3자가 키를 자동차의 소유자 몰래 복사했을 경우에는 자동차 도난 위험이 발생되는 문제점을 해소하기 위하여 차량 인스트루먼트 판넬의 일측 소정부위에 전자제어장치를 이용한 음성인식 자동차 시동장치를 구비함으로써 자동차의 키를 분실했을 경우 뿐만아니라 자동차의 키를 어디에 두었는지 생각 나지 않는 경우에도 차량의 시동을 걸수 있게 함과 더불어 자동차 소유자 이외의 제3자가 자동차를 도난하는 것을 방지할 수 있도록 경보음을 발생시켜 자동차의 도난을 미리 방지할 수 있는 효과가 있다.The present invention relates to a starting device for a vehicle, and in the related art, since a vehicle is started using a vehicle's key, the vehicle cannot be started when the vehicle's key is lost or the car's key is not remembered. In addition, there is a burden of having to carry it all the time, and in order to solve the problem of car theft risk when a third party copies the key secretly of the owner of the car, voice recognition using an electronic control device on one side of the vehicle instrument panel is performed. Having a car starter allows you to start your car not only when you lose your car's key, but also when you don't remember where you put your car's key, and to prevent third parties other than the car owner from stealing your car. To generate an audible alarm There is an effect to prevent theft in advance.

Claims

An input unit 100 installed at one side of the vehicle instrument panel to input a voice input and a selection signal, and an adjusting unit 200 connected to the input unit 100 and processing the input signal according to a predetermined method; The vehicle starting device is configured to be connected to the control unit 200 and the output unit 300 for outputting the processing result signal of the control unit 200.

The method of claim 1, wherein the input unit 100 receives a voice signal from the outside and converts the voice signal into an electrical signal, an ON button, OFF button, registration button, release Car starting device, characterized in that consisting of a selection button panel 120, such as a button.

According to claim 1, wherein the adjusting unit 200 and the conversion unit 210 for converting the input signal transmitted from the input unit 200 so that the central processing unit 222 in the electronic control unit 220 can recognize The electronic control unit 220 is connected to the conversion unit 210 and compares the voice input signal with the voice stored in the main memory 223 to determine the operation of the starter. Starter.

The method of claim 3, wherein the conversion unit 210 is a signal amplifier 211 for amplifying the input signal transmitted from the condenser microphone 110, and the voice recognition of the analog input signal amplified from the signal amplifier 211 A low pass filter (212) for receiving only a voice signal of 5kHz or less required, and a sequential comparison-type AD converter (213) for converting the filtered input signal into a digital signal.

According to claim 1, wherein the output unit 300 is an alarm when the input unit and the operating unit 310 consisting of a solenoid switch 21 to operate the starter when the correct input is input three times or more wrong Starting device for a vehicle, characterized in that consisting of an alarm sound generator 320.

In the operation control method of the vehicle starting device, when the power is turned on (step 10) in the start step, the count value of the latch counter is cleared to A = 0 (step 11), and the audio input signal from the microphone 110 A signal amplifier 211 and a low pass filter 212 to receive the input signal of the selection button panel 120 (step 12) so that the input signal can be recognized by the central processing unit 222 in the electronic control unit 220. And converts by the AD converter 213 (step 13) and compares the converted voice input signal with the audio signal recorded in the main memory 223 by the central processing unit 222 (step 14) and confirms the selection button. (Step 15) If the ON signal is input, start the operation (Step 16). If the OFF signal is input, start the operation (Step 17). If the registration signal is input, the new vision input signal is registered (Step 18). Start signal field using voice input when signal is input In addition, the central processing unit 222 compares the input signal with the voice recorded in the main memory unit 223 and increases it to A = A + 1 (step 21). The value is compared with the fixed integer value 2 (step 22). At this time, when A is smaller than the integer value 2, the state is returned to the state before input (step 23). When A is an integer value 3 or more, the alarm sound generating unit 320 A start operation control method comprising a series of processes for operating (step 24).
