Hereinafter, the operation of the present invention will be described in detail based on these functions.

1.Front vehicle speed detection function

The ECU 5 periodically controls the front ultrasonic transmitter 1 so that when the emitted ultrasonic signal is reflected by the vehicle in front and is incident on the front ultrasonic receiver 2, the detected ultrasonic signal and the signal input from the vehicle speed sensor Calculate the speed of the vehicle ahead.

Then, the current own vehicle speed and the front vehicle speed are written to the HDD 6.

Therefore, although not shown, the ECU 5 is a power regulator, an analog-to-digital converter, a shift register, a digital signal processor (DSP), a program processor, or the like. It is composed.

2. Rear vehicle speed detection function

The ECU 5 periodically controls the rear ultrasonic transmitter 3 so that when the emitted ultrasonic signal is reflected by the rear vehicle and is incident on the rear ultrasonic receiver 4, the detected ultrasonic signal and the signal input from the vehicle speed sensor Calculate the speed of the rear vehicle using.

Then, the current own vehicle speed and the rear vehicle speed are recorded on the HDD 6.

3, front vehicle approach distance measurement function

When the ECU 5 determines that the reverse gear side reverse switch is in the "off" state, the ECU 5 controls the front ultrasonic transmitter 1 so that the emitted ultrasonic signal is reflected by the vehicle in front of the vehicle and is incident on the front ultrasonic receiver 2. The distance from the front vehicle is calculated using the detected ultrasonic signal, and the data is recorded in the HDD 6.

At this time, when the proximity distance of the front vehicle is less than 10m, if the speed of the own vehicle and the front vehicle is 50Km / h or more, and the speed of the own vehicle is 10Km / h or more faster than the speed of the front vehicle, the driver operates the horn Induce safe driving by alarming to secure a safe distance (eg 100m of Gyeongbu Expressway).

On the other hand, when the speed of the front vehicle is 100 Km / h or less and the brake switch of the own vehicle is in the "on" state, the ECU 5 automatically performs the rear vehicle approach distance measurement function mode described later.

4, rear vehicle approach distance measurement function

When the ECU 5 confirms that the reverse gear side reverse switch is in the "off" state, the ECU 5 controls the rear ultrasonic transmitter 3 so that the emitted ultrasonic signal is reflected by the rear vehicle and is incident on the rear ultrasonic receiver 4. The distance from the rear vehicle is calculated using the detected ultrasonic signal, and the data is recorded in the HDD 6.

Using the calculated distance from the rear vehicle and the rear vehicle speed, the ECU 5 performs emergency light control as follows for safe driving.

If the rear vehicle's proximity distance is less than 10m and the rear vehicle speed is more than 100Km / h, the driver's emergency light is operated for a certain time (for example, 15 seconds) to induce the driver of the rear vehicle to maintain a safe distance.

In addition, when the rear vehicle is more than 10m but not more than 140km / h, the emergency light continues to operate until the safety distance (100m of the Gyeongbu Expressway) is maintained to induce the driver of the rear vehicle to maintain the safety distance. Activate the horn once to alert the driver to pay attention to the rear vehicle.

If the brake switch of the own vehicle is in the "on" state while the rear vehicle is detected, the emergency light continues to operate, and when the rear vehicle approaches 10 m or less and the rear vehicle speed is less than 30 km / h, Second) After starting the emergency light, stop the emergency light.

If the rear vehicle speed is 10Km / h or less and the brake switch is "on" and the rear vehicle and the distance are 3m or less, the ECU 5 determines that the vehicle is in a standstill condition and operates the emergency light for a predetermined time (for example, 15 seconds).

However, the direction indicator switch or emergency switch operation by the driver is given priority over the emergency light control function of the ECU 5 described above.

In other words, when the turn indicator switch or the emergency switch is operated in the "on" state in the ignition key switch "on", the turn indicator switch or the emergency switch by the driver will be given priority over the emergency light control function by the ECU (5). When the driver's will operation ends, the emergency light control function by the ECU 5 is resumed.

5. Rear object monitoring function

When the vehicle reversing switch is in the "on" state, that is, when the vehicle is retracted, the ECU 5 controls the rear ultrasonic transmitter 3 when the emitted signal is reflected by the rear object or a person and is incident on the rear ultrasonic receiver 4. The distance between the object or the person and the vehicle is calculated using the incident ultrasonic signal and recorded on the HDD 6.

When the calculated distance is less than 2m, the ECU 5 operates the horn for a predetermined number of times (e.g. two times) and operates the emergency light for a predetermined time (e.g. 15 seconds) to allow the driver to recognize the rear object and to drive safely. Encourage them to do it.

6. Anti-theft surveillance

The ECU 5 "turns on" the burglar alarm reset switch 11 once when the vehicle start key switch is in the "off" state and each door switch (four in the case of four doors) is "off." After switching the door lock / open switch to the locked state within a predetermined time (for example, 3 minutes), the final “off” of all the door switches activates the anti-theft monitoring function. At this time, the control signal is output so that the burglar alarm function operating lamp 10 blinks.

When the driver activates the anti-theft monitoring function, it is preferable to adjust the front / rear infrared CCD cameras 7 and 8 to face the door so that the surveillance of the external intruder is easy.

While the anti-theft monitoring function is in operation, when the ECU 5 does not detect the open signal of the door lock / open switch, it detects that even one vehicle door switch is in an “on” state, or the open signal of the trunk lock / open switch. When the trunk switch 15 detects the "on" state without detecting the state, the horn is continuously operated to alert the intrusion of an outsider.

At the same time, the ECU 5 continues to transmit telephone call signals through the antenna 13 to the driver's telephone, home automation system, cellular phone, and the like.

In case of theft alarm, ie the starter key switch is "off", the door switch "on" when the burglar alarm switch is "on" once, there is no door lock / open switch signal, or the trunk lock / on in the trunk switch "on" state. In the absence of the open switch signal, the front / rear infrared CCD cameras 7 and 8 and the microphone 9 are operated to collect images and sounds around the vehicle and record them on the HDD 6. In the present invention, since an infrared camera is used, even when an outsider invades at night, an image of the surrounding situation can be clearly photographed.

To release the anti-theft monitoring function, turn on the anti-theft alarm reset switch 11 twice, then the ECU 5 releases the anti-theft monitoring function and turn off the anti-theft alarm operation lamp 10. The operation of the front and rear infrared CCD cameras 7 and 8 and the microphone 9 is stopped.

7. Front and rear clock situation video and sound recording function

The ECU 5 performs the front vehicle speed detection function and the front vehicle approach distance measurement function in the vehicle driving state (start key switch "on" or vehicle speed sensor signal generation detection, reverse switch "off"), and thus the front vehicle and the When the distance of the vehicle is 10 m or less, the front infrared CCD camera 7 and the microphone 9 are operated to record an image of the driving situation and the driving lane condition of the front traveling vehicle and the ambient sound on the HDD 6. Record the speed and approach distance of the vehicle ahead.

In addition, the ECU 5 performs the rear vehicle speed sensing function and the rear vehicle approach distance measurement function in the driving state, and when the distance between the rear vehicle and the own vehicle is measured to be 10 m or less, the rear infrared CCD camera 8 and the microphone 9 ) And record the image of the driving situation and the driving lane of the rear driving vehicle and the surrounding sound on the HDD 6 together with the speed and the approaching distance of the front vehicle.

In addition, even when the vehicle is parked (start key switch "off" or vehicle speed sensor signal detection is not detected, reversing switch "off") and the burglar alarm detection function is activated, the front / rear infrared CCD camera (7) even when theft alarm is caused by an external intruder. , 8) and the microphone 9 to record the front and rear clock situation image and the ambient sound on the HDD 6.

In the case where long time front and rear clock situation images and ambient sound are collected and recorded on the HDD 6, the capacity of the HDD 6 is limited so that the user may invalidate the video and audio data recorded on the HDD 6 as necessary. The present invention includes a video / sound recording reset switch 12.

When the user "turns on" the image / sound recording reset switch 12 once, the ECU 5 recognizes this and stops performing the front and rear clock situation image and sound recording functions. In addition, when the user "on" the video / sound recording reset switch 12 two times in succession, the ECU 5 recognizes this and resumes the execution of the front and rear view clock image and sound recording functions. At this time, the contents recorded sequentially from the start point of the video / audio recording area of the HDD 6 are invalidated, and the HDD 6 is controlled to record the video and sound from the first start point of the video / sound recording area of the HDD 6. .

In addition, when the image / sound recording area of the HDD 6 becomes full while the front / back clock situation image and the sound recording function are performed, the ECU 6 causes the HDD 6 to be empty. The HDD 6 is controlled so as to overwrite from the first starting point of the video / audio recording area.

Since the HDD 5 is detachable from the ECU 5, the HDD 5 can be connected to a personal computer (PC) to reproduce the recording.

Therefore, the front and rear clock situation image and ambient sound data recorded on the HDD 5 when driving a vehicle can be utilized as important data for identifying the cause and responsibility of accidents during an accident. The surrounding video and sound recorded in 5) can be easily confirmed by the intruder after theft accident due to outsider intrusion.

8. Vehicle bearing display and recording function

The ECU 5 receives the bearing data of the current vehicle which is input from the bearing sensor 14 when performing the forward / backward clockwise image and the audio recording function in the vehicle driving state or the parking state described above, and displays the HDD (HDD) together with the image and sound data. Record in 6). Current vehicle bearing data enables more accurate identification of causes and responsibilities of accidents.

In addition, the bearing of the vehicle is always displayed on the marking device of the bearing sensor 14.

As described above, according to the present invention, the data stored in the recording medium in case of an accidental vehicle accident (image of the vehicle forward and backward clock, the voice of the driver and the surrounding sound, the speed and orientation of the vehicle, the speed of the front and rear vehicle, and the distance between the front and rear vehicle) By using), it is possible to clarify the cause analysis and responsible material of the vehicle accident, thereby preventing incidence of accidental damage.

In addition, by calculating the driving speed and distance of the front and rear traveling vehicles and their vehicles, when the safe driving is required, the vehicle can be prevented by inducing safety driving by alerting it.

In addition, it detects outside intrusion and wirelessly alerts the remote driver along with the sound alarm so that the outside can be remotely checked to take appropriate measures.The data stored in the recording media (videos of the front and back of the vehicle, The driver's voice, ambient sound, and own vehicle orientation) can be used to easily identify the post-intruder.

In particular, the infrared CCD camera is adopted, so that the surrounding situation at the time of the accident can be easily checked even for a vehicle accident and theft accident occurring at night.

The technical spirit of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only and not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
