The present invention relates to a vehicle accident monitoring method, and more particularly, in order to prepare for various accidents of a driver and all driving conditions of a driver, a driver selection operation function, an accident monitoring function while driving a vehicle, an automatic transmission of an accident scene, and a damage during a vehicle parking. The present invention relates to a vehicle accident monitoring system that comprehensively performs five major vehicle accident monitoring functions, such as monitoring and theft alarm, through automatic control and manual control.

In the past, it is possible to easily secure accurate accident scenes when an accident occurs while driving a vehicle, to prepare for damage and theft accidents to a vehicle while stopping, and to notify the police or fire department immediately of an emergency situation. Many vehicle accident monitoring and alarm systems have been developed.

In the conventional development, it is difficult to perform a monitoring function in the event of a vehicle accident other than a specific driving situation in addition to performing a limited monitoring function for a certain accident situation among a certain driving situation of a driver and a vehicle. However, even though the detailed functions of each development are somewhat different, the monitoring function performed as the main function in preparation for a certain accident situation during a specific driving situation is a driver selection operation function, an accident monitoring function during a vehicle driving, an automatic transmission of an accident scene, and a vehicle parking. It can be organized into five functions: damage monitoring function and theft alarm function.

In other words, in order to prepare for various accidents among all driving conditions of the driver and the vehicle, it means that comprehensive execution of the five main vehicle accident monitoring functions is required, and the present invention is called a vehicle accident monitoring function.

However, the conventional development fails to suggest the concept and method of the vehicle accident monitoring function through the comprehensive execution of the five major vehicle accident monitoring functions. Access, contact, and shock detection signals detected from two sensors, acceleration / deceleration and braking of the vehicle speed, and the presence / absence of the opening and closing of the micro-current of the body are used as incident input signals. In order to avoid malfunctions of control devices due to interference, device malfunctions in the case of approach, contact, shock, etc., other than the sensor mounting part, and accidents when detecting below a set value, it is not possible to solve the problems of control means and complicated device configuration that have to be increased. Because.

In order to solve the above problems, the present invention has five main functions: driver selection operation function, accident monitoring function during vehicle driving, damage monitoring function during vehicle parking, and anti-theft alarm function in preparation for various accident situations among the driver and vehicle. The purpose of the vehicle accident monitoring system is to provide a vehicle accident monitoring system that can protect driver and vehicle safety and reduce the enormous social loss caused by traffic accidents by comprehensively performing the vehicle accident monitoring function through automatic control and manual control.

The present invention for achieving the above object is a step of determining the vehicle driving situation through the ignition switch unit 20, determining whether the driver selection operation via the selection operation switch unit 60, the retractor seat belt unit ( 30) and determining a vehicle collision accident while driving through the vibration detection sensor 40, and determining driver safety through the selective operation switch unit 60, the steering angle sensor unit 50, and the vehicle speed sensor unit 10.

The configuration of the present invention will be described with reference to FIG. 1 block diagram as follows.

The vehicle speed sensor unit 10 mounted on the vehicle wheel detects the vehicle speed 0 km / h? During driving monitoring by the CPU unit 70 to determine driver safety based on whether the vehicle is driven (S11) and photographing operation (S3). The vehicle information nkm / h while driving is recorded in the driving information output unit 80 for performance.

The ignition switch unit 20 detects the vehicle starting on / off by the CPU unit 70 so that the CPU unit 70 determines the vehicle driving situation and the driving monitoring process (S3, S4, S5), when the vehicle is stopped. Have a parking monitoring process (S1, S6).

The retractor seat belt unit 30 is a driver sitting in the driver's seat to drive the vehicle diagonally (S2) from the upper left to the lower right of the driver's seat, so that the front, rear, left, In the case of a sudden shock occurs while the belt locking operation (S5) for the driver's safety while detecting the impact signal to the vibration detection sensor 40 and the CPU 70 for the vehicle crash accident determination.

The vibration sensor 40 detects all vibration values OP generated in the entire vehicle body.

When the ignition switch unit 20 is turned on (S1), and a vehicle impact accident occurs during the driving monitoring process (S3, S4, S5), when the driver shock generation signal is detected by the retractor seat belt unit (S5), a vehicle shock occurs. When the vibration value Q is set so that the OP value is greater than or equal to the Q value, when the OP value is greater than or equal to the Q value, the vehicle shock occurrence signal is detected by the CPU unit 70 to determine the occurrence of a vehicle crash (S6). Is set to OFF (S1) so that the vehicle abnormality occurrence vibration value R is set during the parking monitoring process (S1, S6), and the CPU unit 70 determines the vehicle fault occurrence when the OP value is equal to or greater than the R value. The vehicle fault occurrence signal is detected at step S6.

Therefore, the CPU 70 detects abnormal vibrations in the vehicle during the driving monitoring process (S3, S4, S5) and during the execution of all vehicle collision accidents and the parking monitoring process (S1, S6). When all vehicle abnormalities occur, it is determined that a clear vehicle accident occurs to perform the recording operation (S7).

It is possible to solve the problem and through the vehicle abnormality detection method using the vibration sensor unit 40, the device in case of theft occurrence due to the damage of the window, which is held by a general burglar alarm device that determines whether the door of the vehicle is opened or closed without using the main key. The problem of malfunctions can be solved.

The steering angle sensor unit 50 installed in the steering shaft detects 'no steering angle change for L seconds' in the CPU unit 70 in order to determine driver safety through driver driving operation (S10).

The selection operation switch unit 60 is equipped with recording, output, transmission, cancel transmission, and reset buttons, and outputs a manual control signal to the CPU unit 70 according to the driver's selection during the driving monitoring process (S3, S4, S5) (S4). , S8, S9).

Therefore, the driver should immediately contact the vehicle during the driving monitoring process (S3, S4, S5) with respect to the vehicle accidents such as recording, output, transmission, and system initialization in case of minor contact accidents, witnesses between other vehicles, and hits and misses. You will be able to take all necessary steps.

It outputs the activating signal to the storage unit 100, a display unit 110, a horn 120.

The driving information output unit 80 is operated by receiving an operation signal from the CPU unit 70 and detected by the vehicle speed sensor unit 10 to perform the shooting operation S3 for the driving monitoring processes S3, S4 and S5. The vehicle speed nkm / h is input through the vehicle speed interface 81, and the left and right turn signals, the brake light, the reverse light, the warning light, and the headlight operation signals that the driver makes for driving the vehicle are input through the multifunction switch fuse box 82. The vehicle driving information made of a single digital signal is output to the storage unit 100.

The external image photographing unit 90 operates by receiving an operation signal from the CPU unit 70 so as to accurately capture the surrounding image of the vehicle for performing the photographing operation S3 for the driving monitoring process S3, S4, S5. By operating the CCD cameras 91 to 94 mounted on all sides, the vehicle external image is taken, and this image signal is made into a single synchronization signal through the multiplexer 95, and the external signal made into a digital signal through the A / D converter 96. Outputs the image information to the storage unit 100.

The storage unit 100 operates by receiving an operation signal from the CPU unit 70 to output the vehicle from the driving information output unit 60 to perform the shooting operation S3 for the driving monitoring process S3, S4, or S5. After synthesizing and processing the driving information and the external image information output from the external image capturing unit 90 into a single digital image signal through the signal control controller 101, the image signal is converted into a first memory 102 and a second memory. When the storage of one memory is finished through 103, the temporary storage function of continuing the storage in the other memory is repeatedly performed.

At this time, when the CPU unit 70 that determines the occurrence of a vehicle crash accident from the retractor seat belt unit 30 and the vibration detection sensor unit 40 (S5, S6) outputs an operation signal, the photographing operation S3 is performed. It stops the temporary storage function for performing the recording operation (S7) for permanently storing the accident scene before and after the accident time point stored in the first memory 102 and the second memory 103 in the ROM (104).

In addition, the storage unit 100 is a CPU unit 70 that determines the occurrence of the vehicle abnormality from the vibration sensor unit 40 that detects the occurrence of the vehicle abnormal vibration during the parking monitoring process (S1, S6), the driving information output unit 80, When the external image photographing unit 90 and the storage unit 100 are operated, a recording operation S7 is performed to permanently store the accident scene after the accident point in the ROM 104.

The display unit 110 operates by receiving an operation signal from the CPU unit 70 to convert the digital image signal stored in the ROM 104 into an analog signal through the D / A converter 111 and through the screen split controller 112. It is possible to analyze the driving information before and after the accident point and external image information of the vehicle in one screen at the time of outputting the accident scene through the monitor 113 and transmitting the accident scene through the mobile phone 114 through four-segmented imaging. .

Thus, it is possible to secure accurate accident scenes including vehicle driving information when handling traffic accidents after a car accident.In particular, accident scenes are transmitted from the mobile phone 114 to the police station or the fire department in case of an emergency due to an accident occurring in a rare place. With satellite positioning, the driver can immediately receive emergency relief.

In addition, when the driver carries the mobile phone 114 and the vehicle abnormality occurs during the vehicle stop (S6) to get off the vehicle (S6), the display unit 110 sends a vehicle abnormality generation signal to the driver's mobile phone 114 (S15) immediately Allows you to check the safety of your vehicle.

The horn unit 120 operates by receiving an operation signal from the CPU unit 70, and when the CPU unit 70 that determines the occurrence of a vehicle accident outputs an operation signal, generates a vehicle accident alarm sound for L seconds after recording operation (S7). When the CPU unit 70 determines that the driver's emergency situation is generated and outputs an operation signal, a transmission operation warning sound is generated to the driver for N seconds to determine whether the driver releases the transmission operation (S12).

In particular, when the female driver turns on (S4) the recording button of the selective operation switch unit 60, the accident scene by turning on (S9) the transmission button together with the eradication effect through the vehicle accident alarm sound of the horn unit 120. You will be able to report it immediately.

When the signal is detected at the same time, it is determined that the vehicle crash accident occurs and stops the driving monitoring process and performs the recording operation to generate a vehicle accident alarm sound for L seconds through the horn 120 (S3, S4, S5, S6). S7)

At this time, when the driver is unconscious due to a car crash, the CPU unit 70 outputs and transmits the button for? L seconds through the selective operation switch unit 60 for the automatic transmission of the accident scene. The driver 50 judges the driver's selection and driving operation by determining the steering angle change for L seconds: YES through the unit 50. After L seconds, the vehicle speed sensor unit 10 monitors the driving for M seconds. If the vehicle speed is determined by determining the vehicle speed 0km / h?: YES '(S7, S8, S9, S10, S11) and if the driver's selection operation, driving operation and vehicle driving are not detected for L + M seconds, In order to check whether the transmission operation is released or not, the automatic transmission operation warning sound is generated through the horn unit 120 for N seconds, and the occurrence of the driver emergency is determined by determining the 'release release button ON?: NO' (12) for N seconds. The accident scene is automatically transmitted to the police station or fire station through the mobile phone 114 (S13).

Therefore, the CPU unit 70 automatically records an accident scene during a clear vehicle collision accident determined by the retractor seat belt unit 30 and the vibration detection sensor unit 40 while performing an accident monitoring function while driving the vehicle (S5, S6). (S7) S7, S8, S9, S10, S11, S12, S13 will be executed when there is a clear driver emergency situation where driver safety is not checked for L + M + N seconds after a car crash. )

When the ignition switch unit 20 is turned off, the CPU unit 70 performs a parking monitoring process for determining whether a vehicle abnormality has occurred through the vibration sensor 40 to perform a vehicle parking increase damage monitoring and theft alarm function. S1, S6)

At this time, when a vehicle abnormality occurrence signal is detected from the vibration sensor unit 40 (S6), the CPU unit 70 operates the driving information output unit 80, the external image photographing unit 90, and the storage unit 100. During the recording operation to permanently record the video information after the accident point to the ROM 104, a vehicle accident occurrence alarm sound is generated for L seconds (S7), and the output / transmission button on?: NO for 'L seconds' for L seconds. No change in steering angle: YES, vehicle speed 0km / h?: NO during driving monitoring for M seconds, and whether the mobile phone is removed or not. After S9, S10, S11, S14 and S15, the parking monitoring process (S1, S6) is performed again from the beginning.
