Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device which can be used for prevention of a vehicle accident situation, recording and redisplay of the accident situation, and analysis of the cause thereof. The device of the present invention is attached to a vehicle, and thus monitors the operation of continuously changing the condition of the vehicle operation, the condition of operation, and the environment (other vehicle position, traffic signal light, weather, etc.) and timely. The driver's attention and automatically adjust the condition of the car to maintain the safety when the car is running and when it is parked, and at the time of the car accident (before and after), After the data is recorded, the situation of the accident at that time is again displayed through one device and the cause is analyzed and used as a reference for training or insurance affairs. In particular, automatic monitoring and recording of accidents can automatically generate an alarm when an accident occurs, prevent the occurrence of chained car accidents, and make it possible to leave an accident immediately from the scene and make traffic smooth. it can.

2. Description of the Related Art Causes of traffic accidents are driver's operating conditions (sleeping, drunk, meandering / speeding over, not keeping traffic signal instructions, etc.), vehicle conditions (element failure or original design failure), weather However, complicated factors such as road conditions (defects of road facilities, etc.) are intertwined, but most of the causes belong to driver's unsafe operation, car element failure, bad weather, etc. Accidents can be prevented and damage can be reduced if timely or early warning is given. Furthermore, if there is a risk of overturning, for example, because the vehicle is curving at an excessive speed, if the vehicle has appropriate observation and actuation devices and the vehicle speed is reduced in a timely manner, the occurrence of an accident can be avoided.

If a car accident has occurred in the past, it is necessary to keep the condition of the scene as it is and wait for the police or the car accident appraiser to arrive at the scene and measure the situation of the accident and complete the picture record. Since the site cannot be immediately processed, it misses the opportunity to save people and spreads the damage, and on the other hand, it obstructs the passage of vehicles by other people, which causes subsequent chain car accidents. Then, at the scene of the accident occurrence, judgment is made based on trivial materials such as post-correlation positions drawn by the expert appraisal personnel and / or traces of possible sudden braking, or statements of the person involved in the accident and witnesses. Then, if the parties excuse themselves in their favor or are fooled, or if they are surprised too much, the memory is disturbed and the contents of the statements contradict each other, or they are treated unfairly due to lack of dialect. As a result, it is not possible to determine the true data on the accident site, and therefore it is not possible to accurately and fairly judge the responsibility for the accident. For insurance companies underwriting damages, because they cannot grasp the true situation, they are always forced to make damages that are not originally responsible for it, and the loss is passed on to all insurance participants and The current situation is that insurance premiums are too high. In addition, it lacks a complete record of the actual situation of the accident, so it is not possible to accurately analyze the cause of the accident or to obtain any information that would be useful for subsequent improvement, and therefore the same type of accidents often occur thereafter. Is inevitable.

In the case of parking before, the anti-theft or protection device is
It only prevents the car from being stolen by issuing an alarm or stopping the engine after it senses that the car is impacted and vibrates.It prevents the occurrence of an accident and the process and accident in which the car was harmed. After the car is damaged, the owner of the car has no evidence to base the compensation on because the data of the person who caused the accident cannot be recorded. In addition, it is impossible to prevent the occurrence of an accident because the previous vehicle does not have a device that monitors the operation status of the vehicle and controls the warning and complete driving based on this.

In order to solve the above-mentioned problems, the present invention monitors and assists the safety situation of the operation and parking of the vehicle at any time to prevent the occurrence of an accident, and in the case of the occurrence of the accident, the material related to the vehicle and the outside world. We will provide a device that can record and record the situation and re-display the situation at the time of the accident with post-script and video, and analyze and judge the cause. Although some of the purpose of the data record on the operation of vehicles and the occurrence of accidents with this device is similar to the black box of airplanes, the operation status of vehicles and traffic conditions on the road surface and traffic rules are similar to those in the air. Since it is completely different, the black box cannot be quoted in the car, and the recorded contents of the black box are officially approved after the judgment of an expert, and the black box itself directly redisplays the situation at the time of the accident or automatically. It does not have sufficient data or efficacy to be used for analysis of the cause.

Since it achieved, and a description thereof will be omitted.

The minicomputer 1 performs monitoring and control operations by the above-mentioned various observation devices, which includes an operation recording mode M1 and a parking protection mode M2, the program of which is described in detail with reference to FIGS. There is. In addition to this, the time signal device 26 provides time signals of year, month, day, hour, minute, and second to the minicomputer for operation, and the receiver 3 receives information about road conditions such as accidents caused by other vehicles or It serves to receive a remote control signal sent by a receiver / transmitter attached to the present invention. The observation signals and information of the above items are minicomputers 1
The signal generated after being processed is exported via a warning device 4, an actuator 5, a transmitter 6, a permanent recorder 7 and the like. Among them, the alarm device 4 includes a display and an alarm device, and provides information about safety or instructions to the car owner or other persons by means of light signals, voice and graphic displays, and the actuator 5 is a triber When it is determined that the minicomputer 1 has an accident, the transmitter 6 includes various operating devices for assisting the operation, such as a brake actuator and a light controller. It notifies other cars (when the car is running) and causes them to take appropriate processing immediately. The most important thing is that the minicomputer 1 has a register 17 and each normal observation device 2
The signal data that has been stored for a while at 0, 22, 24 is continuously updated, and once an accident occurs, this is recorded permanently by a permanent recorder (eg, programmable read-only memory PROM) 7
However, the permanent memory 7 has a protective case having a function of preventing damage (loss, waterproofing, magnetic field prevention, collision prevention, electric shock prevention and resolution prevention) and an anti-counterfeit material structure. , Withhold complete documentation (including basic documentation such as vehicle license number and engine number and vehicle type entered when the system was installed with the vehicle) and post-fact directly or via the record reading card 8. And input to the re-display / analysis device 9. Therefore, it is to display the process of the accident occurrence, provide the cause of the accident occurrence, and help judge the responsibility of the accident occurrence. The operation between the minicomputer 1 and each of the input and output devices will be described in detail below.

FIG. 2 shows how the object position / distance sensor 250 and the camera 254 are attached according to the present invention.
The object position / distance sensor 250 has a plurality of ultrasonic, laser or infrared distance measuring and temperature remote sensing elements 250a mounted at appropriate positions around the vehicle body V for observing in its individual zone direction A and It mixes with the motion of V to generate a scanning effect on objects outside the vehicle, and observes the surrounding environment. The camera 254 consists of several simple solid-state imaging elements 254b (individually a metal oxide semiconductor MOS or charge coupled element CCD).
A matrix set with one suitable lens) is mounted at a suitable position around the vehicle body V to take an image of the outside world, and the image ranges B thereof overlap each other at an appropriate distance outside the vehicle. To cover the entire circumference.

These photographing elements 254 share one driving element (not shown) so that the composition of the apparatus can be made compact, and the necessary photographing elements are controlled by the minicomputer 1 to sequentially connect and collect video signals. That is, when it is determined that an accident has occurred, it is mixed with the observation data of the object position / distance sensor 250 and the six-direction acceleration sensor 230 (FIG. 1), and the permanent image recording material with the azimuth corresponding to the accident is recorded for the first time. To reduce the number of materials.

FIG. 3 is a flow sheet for executing the functions of monitoring, controlling and recording the vehicle operation according to the present invention, that is, a program for operating the vehicle operation recording mode M1 in the minicomputer 1 of FIG. This program starts operating when the car starts (S10), and first checks whether the system is normal (minicomputer 1 outputs a test signal and feeds
The back signal is inspected, so that itself and each output,
Confirm that the input device is operating normally) (S1
1) If the system is out of order, if the extent of the outage is minor, the driver is alerted to the failure item and corrective action to be taken within a certain length of time (S13), and at the same time the vehicle operation is stopped. Beginning monitoring (S12), if the failure is severe, for example, when a large number or important sensors are ineffective, warning measures against the failure and warning that the travel distance should be limited are sent to the car for repair. (S14), the warning is stopped only after the driver presses the key to confirm, and the monitoring is started after the car starts running (S15) (S15).
(12, S16), it warns how long the car will stop after running (S17), and when the distance to stop is reached (S18), the engine is stopped and the monitoring ends (S1).
9, S20). When monitoring vehicle operation, the values read by each sensor and traffic light are sequentially read (the frequency of reading individual observation values is determined based on the rate of change and the importance of each, and it is set to 1 for every 1 km or 20 ms). (In principle, read once.) (S12), register 1 with time signal
7 (FIG. 1), the register 17 holds only the most recent record (for example, within 20 seconds) (S22). Among the read numerical values, the portion observed when the vehicle body is hit or abnormally moved, for example, the observed values of the six-direction acceleration sensor 230, the object position distance sensor 250, and the sound pickup device 231 indicate whether or not an accident has already occurred. Is used to judge. When it is determined that an accident has occurred, the minicomputer 1 (Fig. 1) immediately issues an accident signal, is received by the receiver 3 of the nearby car via the transmitter 6, and activates the alarm device 4 to produce speech sounds, etc. Alerting the driver to take appropriate action, at the same time the record in register 17 is compressed and then permanent recorder 7
(S26), and the observation values of each sensor after the occurrence of the accident are stored in the continuous register 17 (S27, S2).
8) After the stationary of each observation value reaches a certain time (for example, 20 seconds), the record of the register 17 is recompressed and transferred to the permanent recorder 7, so that a complete document about the process before and after the accident occurs. System inspection (S11) from the time the record is completed to the time the vehicle is stopped (engine stopped)
Re-start the circular program starting from.

In addition to this, although no accident has occurred, the minicomputer 1 tends to be dangerous due to the numerical value indicated by an arbitrary sensor or the numerical value indicated by each sensor (for example, there is a possibility of collision, bumping or tipping over). Yes, brake abnormality, engine overheat, door not locked, light failure, dark or foggy but no light, etc.) (S23) A control signal is output to the warning device 4 and a specific actuator 5 to warn the driver of this vehicle of a dangerous situation and appropriate measures, and automatically control the situation of the vehicle (for example, brake deceleration, light External safety warning by blinking and buzzer, automatically locking doors and turning on lights, etc.) (S24) to improve safety while driving.

In addition to the above-mentioned effects of monitoring and recording the operation of the vehicle, the present invention can also perform the effects of safety protection such as theft prevention, collision prevention and accident record which suffered damage during parking. FIG. 4 is a composition block diagram of the effect of parking protection of this device (parking protection mode M2 in the minicomputer 1),
This is essentially a portion of the entire system of Figure 1 (all identical members are numbered the same). The contents of the mini-computer 1 executing the parking protection mode are roughly: mode open / close S50, S70, system inspection S51, safety protection control S54-56, automatic charge control S80, correlation warning signal interface 14 and control signal interface 15. And a register 17 and the like. The tactile movement of the mode open / close S50 can be remotely controlled outside the vehicle via the receiver 3 by the receiver / transmitter 19 owned by the vehicle owner, or by the secret owner outside the vehicle.
It can be opened or closed by operating each code key. As shown in the action blow charts of FIGS. 5A and 5B, the mode open (S5
In 0), firstly, a system inspection (S51) is executed to check whether the input and output devices of each correlation are operating normally, and whether the car is reasonably stopped (that is, the main
Switch signal device 201, shift signal device 205, hand
Brake signal device 207, light switch signal device 20
9, door signal device 211, window signal device 212, wiper blade signal device 213, defoaming / defoaming signal device 214
And whether the observed values of the security signal device 216 and the like all represent a closed state), and if they are abnormal, the display 41 and the alarm device 42 warn of abnormal matters and the status of limitation (for example, , The existing sensor has already expired and the protection effect is not produced) (S52), and the monitoring and protection program is executed after confirmation or correction by the user. To save power, the grid normally operates relatively infrequently, as well as the six-way acceleration sensor 230, sound collector 231, light sensor 241, interior and exterior temperature gauge 242, object position / distance sensor 250, camera 254. And time signal device 2
6 etc. The observation value of each observation device is read (S54), it is stored in the register 17 for a while, the register 17 automatically deletes the record before the fixed time (S56), and the minicomputer 1 has an accidental abnormality based on the observation value. For example, it is judged whether the vehicle body is hit, destroyed, intruded, illegally activated, or the like (S55). If it is recognized that these accidents are occurring, the minicomputer 1 sends the warning signal surface. An accident occurred from 14 and the transmitter / receiver 19 of the car owner passed through transmitter 6.
Call or call the alarm with the alarm 42 to alarm the thief, and at the same time drive the lock actuator 53 via the control signal interface 15 to lock the vehicle body and drive the oil / electric disconnector to stop the engine. (S59), at the same time, the record of the register 17 is compressed and then moved to the permanent recorder 7 (S60). After the occurrence of the accident, each sensor operates at a relatively high frequency and the observed value is stored in the register 17 (S61, S62). ), After each observation value has been stationary for a certain period of time (becomes normal), the record in the register 17 is compressed again and moved to the permanent recorder,
This completes the recording of the complete data of the pre- and post-procedures of the accident (S63, S64), and the minicomputer 1 calculates the outline (time, nature, part, etc.) of the accident situation, which is not shown for a while. (S65), then the circulation program is restored starting from the step (S54) of monitoring at a much lower frequency until the vehicle owner closes the protection mode (S70). When the protection mode is closed, the display 41 first provides the vehicle owner with information regarding the above-mentioned outline of accident protection that has been entrusted for a while, and the vehicle owner confirms and processes the information and then ends (S71, S72, S73). In addition to this, although no accident has occurred, the mini computer 1 tends to be dangerous due to the numerical value indicated by an arbitrary sensor or the numerical value indicated by each sensor, for example, there is a possibility of being hit by a vehicle running at high speed. If it is estimated that there is, or if the temperature inside the vehicle is too high or if the window is covered with ice (S
57), outputting a control signal corresponding to the control signal via the control signal transmitting surface 15 to a specific actuator, for example, driving a warning light actuator to call attention to the driver of the other vehicle, or ventilation not shown. Alternatively, activate a defoaming device to ensure the safety of this vehicle. In addition, when the power supply 10 of this car has insufficient power (sensed by the battery sensor 229) but still has a sufficient amount of oil (sensed by the oil gauge), control is performed by automatic charging control (S80). The control signal is output to the engine start actuator 55 and the accelerator actuator 56 via the signal interface 15 and the engine power supplier 10 based on the observed value of the engine speed meter 221.
The optimum rotation speed for charging the battery, and at the same time, the cooling water sensor 224, the cooling fan 225, and the grease sensor 2 are controlled.
26, oil gauge 228, and battery sensor 229 observations are monitored to control the engine to operate safely until the power supplier 10 is charged to some reasonable degree. However, in order to avoid the exhaust problem caused by the engine operating indoors, this automatic charging program is not applied indoors, and instead, the minicomputer 1 uses the observation values of the object position / distance sensor 250 and the like to determine the environmental conditions. When it is determined that the person belongs to the room, the user is asked to confirm the status of this restriction at the beginning of the mode open (S52, S5).
3).

As described above, the present invention compresses the signal processing observed before and after each accident occurrence and deposits it in the permanent recorder 7, but most of the observed values are 1 bit (presence or absence). Since the signals of the sound collector 231 and the camera 254, which are materials and have a relatively large number of bits, store the materials of the most important time zone, if one permanent recorder 7 having an appropriate capacity is prepared, It is possible to record the accident and the condition of the vehicle every time the vehicle is used. This record is present together with the vehicle and can be used for any visa application, and serves as a basis for the vehicle safety inspection and the vehicular operation record visa, for example, by the government office that administers the vehicle. In order to secure the authenticity and completeness of this record, the main device such as the minicomputer 1 and the permanent recorder 7 in the present invention adopts a protective design that cannot be removed, disassembled, destroyed or modified, and is installed or replaced. If it is not possible, the government shall stipulate that a visa and registration of the government office of the administration shall be required, and thus the effects of the overall control and operation shall be expected. Further, the material of the permanent recorder 7 is only allowed to be read (including the recording / output interface not shown in the minicomputer 1, which allows the material to be output to a medium such as a memory reading card 8) and its content cannot be changed. Therefore, the decryption should always be carried out on a particular redisplay and disassembly device 9.

FIG. 6 shows a composition of an embodiment of the re-display and analysis apparatus 9 according to the present invention and a program of its operation. The re-display and analysis device 9 mainly includes a lead card 90, a computer 91 and a display control input unit 9.
2 and a shadow sound pictorial display 93 and a rule archive 94. The re-display and disassembly device 9 can read the records of one or several correlated vehicles to make individual or correlation judgments. For example, as shown in the figure, the card reader 90 first controls the computer 91. Based on the basic data in the record reading cards 8A and 8B of the permanent recorders 7A and 7B of each vehicle,
After checking the vehicle name, time, etc. to which the material belongs (S911), and confirming that it is accurate, the computer 91 collects all necessary materials.
In a recorder not shown in the figure (S91
2), prepare for processing. The operation of the computer 91 is actually a re-display program M3 that can be used independently.
And this part of the analysis program M4.

The re-display program M3 first decodes, compresses and divides the vehicle data to reduce it to the original observation values, and performs a related calculation between the observation values (for example, the center of gravity of the vehicle by the numerical values of the six-direction acceleration). And its movement, turn acceleration are calculated), and a reference mix of correlated vehicle data is processed (S913), and video and audio data are also processed into a format that can be displayed (S914), which is necessary for a car accident experiment. Data such as the size, relative position, direction of movement, speed, location and shape of the environment of the vehicle, which are correlated with this vehicle, are those of a series of mobile pictures that occur earlier and change over time. After depositing it in the recorder for a while on the screen, a person who is watching according to various experimental modes prepared in advance selects and adjusts it from the display control input section 92 and collects the screen. To control the experiment Lumpur picture (S916), dynamic graphics, sound, and reproduce the process of the display to the accident on the MV Zubun display 93 a screen that contains the video, makes it obvious to the viewer. The situation of this experiment shows, for example, the time when the accident occurred, the number of cars related to this accident, the model number and license number, the point where the accident occurred, etc. Show the distance between the involved parties on the screen, the mobile picture will first experiment at normal speed, and then again at some speed that it can control, to experiment with some and all of the situations, amplifying, reducing, concatenating, Adjust freely according to the method such as forward and backward. All of these mobile picture techniques can be accomplished with existing computer software technology.

The analysis program M4 goes one step further and causes the computer 91 to use the materials (vehicle operation rules 941, driving operation rules 942, and traffic rules 943) of the rule material store 94.
And the case rule 944, etc.) to assist in the objective judgment and analysis of accident causes and responsibilities. First, after collecting the portion related to the operation of the vehicle itself in the observation values acquired by the vehicle information calculation (S913) and verifying whether there is a record of the failure, the vehicle operation rule 941
Is analyzed (S917), and if the brake pedal is depressed but the hydraulic pressure of the brake is not increased and the vehicle speed is not reduced, it is determined that the brake is not effective. In addition, by collecting a portion related to the driving operation, and analyzing the driving operation 942 and the traffic code 943 to analyze the driving operation error (S918), for example, the speed is over, or an indicator lamp is attached in advance. Find out if you are suddenly changing the roadway. After that, the cooperation of the determination of the cause of the accident is advanced based on the result of the above analysis and the context of the time (S919), that is, the related factors and possible relationships are arranged according to the context of the time, and the personnel are confirmed. Finally, in comparison with the existing case rule 944 and the like, the result of the auxiliary judgment of liability for the accident is provided (S920).
The establishment and operation of the rule archive 94 can be accomplished by conventional expert-based computer technology.

The results of the above-mentioned re-display and the analysis in each stage are all outputted on the display 93 at any time, and can be used as a reference for the appraiser or a person concerned, and troubles can be reduced after the preparation of the person concerned is obtained. , Person responsible for accident (manufacturing or repair factory of individual or automobile, department of public transportation facilities, etc.)
Can be improved based on this, and the insurance company can reasonably determine individual car insurance charges based on this. In addition, the driver who fled after a car accident also holds evidence so that he cannot denounce his mistakes after the fact and encourages the driver to comply with more regulations and pay attention to safety. Besides, the experiment of car accident occurrence process can be a true teaching material for car drivers and enhance the effectiveness of training and learning.
