Abstract

PURPOSE:To provide a means capable of quickly and surely investigating an accident cause. CONSTITUTION:Detected outputs of a brake sensor 2, a steering sensor 3, and an accelerator sensor 4, the data of a speed meter 5, the on/off data of a winker switch 6 and a light switch 7 are recorded on a recorder 8. When theme recorded data are regenerated and analyzed at the time of an accident, an accident cause can be quickly and surely investigated. If a shock sensor 9 is provided, its detected output is recorded on the recorder 8. When a shock at a preset value or above is detected, the recording by the recorder 8 is stopped after the preset period, and the unnecessary use of a memory region can be prevented. In an automobile mounted with a car navigation device 10, the azimuth data of the automobile detected by it are recorded on the recorder 8 to be used for the investigation of the accident cause.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle running recording apparatus, and is particularly used for investigating the cause of a collision accident.

[0002]

2. Description of the Related Art Conventionally, when an automobile accident occurs, the testimonies of the parties and the witnesses' witnesses are the common reliance, and there is usually little concrete evidence. Was not. An object of the present invention is to provide means for speedily and surely investigating the cause of an accident.

[Means for Solving the Problems]

(1) The invention of claim 1 is an automobile travel recording apparatus mounted on an automobile, comprising a brake sensor for detecting an operation state of a brake, a steering sensor for detecting a steering angle, and an operation state of an accelerator pedal. An accelerator sensor for detecting the above is stored, and the detection outputs of the various sensors while the vehicle is traveling, the data of the vehicle speedometer, and the ON / OFF data of the turn signal switch and the light switch are stored in the recorder. (2) In the invention of claim 2, in the vehicle running recording apparatus according to (1), an impact sensor is provided, and the detection output during vehicle operation is recorded in the recorder, and the impact sensor has a predetermined value or more. When the impact is detected, recording by the recorder is stopped after a predetermined time. (3) In the invention of claim 3, in the vehicle traveling recording device according to (1) or (2), the azimuth angle of the vehicle detected by the car navigation device mounted on the vehicle is recorded in the recorder. .

1 is a block diagram showing an embodiment of an automobile traveling recording apparatus 1 of the present invention. In the figure, reference numeral 2 is a brake sensor that detects the operating state of the brake, and can be realized by attaching a switch to the pedal, which is turned on when the brake pedal is depressed and turned off when released. Reference numeral 3 is a steering wheel.
A steering sensor that detects the operation angle of the steering wheel of a vehicle and is attached to the steering wheel. Reference numeral 4 is an accelerator sensor that detects the operation state of the accelerator pedal, and can be realized by attaching a switch to the pedal, which is turned on when the accelerator pedal is depressed and turned off when the accelerator pedal is released, for example.

These various sensors 2, which are in operation while the vehicle is in operation
The detection outputs of 3 and 4, the data of the speedometer of the car, the turn signal switch (switch for turning on / off the blinking direction indicator light of the car) 6 and the on / off data of the light switch 7 are input to the recorder 8. And record. A magnetic tape, a storage card (magnetic card, IC card, optical card), or a storage disk can be used as the memory of the recorder.

When an accident occurs between automobiles and the cause of the accident is to be investigated, the memories built in the recorders 8 of both vehicle traveling recording devices 1 are taken out, reproduced by a reproducing device, and the recorded contents are analyzed. , It is possible to know the driving situation at the time of an accident and the operation support status. If the information obtained by the recorder 8 is added to the testimony of the person involved in the accident and the witnesses, the cause of the accident can be promptly investigated.

When an accident occurs and the vehicle is stopped, the operation of the recorder 8 can be manually turned off in order to avoid wasteful use of the memory area of the recorder 8. However, since it is in a confused state, there is a risk of forgetting to turn it off. Therefore, as shown by the dotted line in FIG. 1, an impact sensor 9 is provided, and the detection output during vehicle operation is recorded in the recorder 8 to give an impact. When the sensor 9 detects an impact of a predetermined value or more, the recorder 8 may be turned off after a predetermined time based on the detected output to automatically stop the operation of the recorder.

When the car navigation device 10 is mounted on the automobile, if the azimuth angle of the automobile detected by the device 10 is recorded in the recorder 8 together with the other data, this azimuth information is obtained. Useful for investigating the cause of the accident. In the above description, the ON / OFF data of the winker switch 6 and the light switch 7 of the automobile are directly recorded in the recorder 8. However, the sensors 11 and 12 for detecting the ON / OFF states of these switches are separately provided on the automobile running recording device side. Alternatively, the detection data may be recorded by the recorder 8.

[0009]

EFFECT OF THE INVENTION If the automatic running recording apparatus of the present invention is installed, the operating conditions and running speeds of the brake, steering and accelerator, and the ON / OFF data of the turn signal switch and the light switch, which are recorded in the recorder, can be analyzed. By doing so, the cause of the accident can be investigated quickly and reliably.
