Abstract

PROBLEM TO BE SOLVED: To easily analyze an accident by storing operational information on a vehicle, positional information and image information on the front, the rear and the side in a nonvolatile memory up to a fixed time from air bag actuating time. SOLUTION: An information recorder 1 inputs operational information 4 on a vehicle 2, image information 6 on the front, the rear and the side of the vehicle 2, vehicle positional information 8 and air bag actuating information 10 on an air bag device 9. The information 4, 6, 8, 10 are processed by the information recorder 1, and are recorded in a nonvolatile memory 11 so as to be brought outside. The nonvolatile memory 11 takes in the information 4, 6, 8 continuously or in a sampling system with every fixed time. Thus, when the vehicle 2 collides or is collided, the information 4, 6, 8 up to a constant time from air bag actuating time of the air bag device 9 is stored in the nonvolatile memory 11, and can be taken out to thereby easily and accurately clear up the truth of an accident cause and a crime.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for recording drive information, and more particularly to a method and apparatus for storing various information for a certain period of time before an airbag is activated by a collision in a non-volatile memory to facilitate accident analysis. New improvements for

[0002]

2. Description of the Related Art Hitherto, as a drive recorder that has been used, a configuration generally called a tachograph is employed, and the speed at which a vehicle travels is recorded for each distance.

[0003]

Since the conventional drive recorder is configured as described above, the following problems exist. That is, since only the speed at the time of traveling of the vehicle is recorded, the information at the time of occurrence of the accident is only the speed. For this reason, in the field inspection of the accident, the actual contents of the victim and the perpetrator were checked, and a record was prepared to estimate the cause of the accident.However, the amount of information was small, and both sides should come to a satisfactory conclusion. Was difficult.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. In particular, when an airbag is actuated due to a collision, various kinds of information for a certain period of time before the airbag is stored in a non-volatile memory to prevent an accident. An object of the present invention is to provide a drive information recording method and apparatus which facilitates analysis.

[0005]

According to the present invention, there is provided a drive information recording method comprising: control information relating to a control of a vehicle; vehicle position information obtained by a GPS of a position of the vehicle; Image information obtained by capturing any or all of the images is obtained continuously or at regular time intervals, and at the time of operating the airbag of the vehicle, the information from the time of operating the airbag to a predetermined time before is stored in the nonvolatile memory. A driving information from a vehicle engine control computer, video information from a video camera provided in the vehicle, airbag operation information when an airbag of the vehicle is activated, GPS, Information recording device for capturing vehicle position information indicating the position of the vehicle according to the present invention, and a nonvolatile memo provided in the information recording device for recording the respective information With bets, wherein until a predetermined time before the time of operation the airbag is configured to store respective information in the nonvolatile memory, the nonvolatile memory has a configuration composed of IC card.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a drive information recording method and apparatus according to the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes an information recording device. The information recording device 1 includes an accelerator opening, a brake amount, a speed, an engine speed, and the like from an engine control computer 3 for controlling an engine of a vehicle 2. And video information 6 obtained by digitizing and compressing (or a well-known image compression technique) any or all images of a video camera 5 attached to the front, rear and side of the vehicle 2.
, Vehicle position information 8 from a car navigator 7 by well-known GPS, and airbag operation information 10 of an airbag device 9 of the vehicle 2 are input.
Reference numerals 8 and 10 are processed by the information recording apparatus 1, recorded in the nonvolatile memory 11 composed of an IC card or the like, and configured to be taken out.

Next, the operation will be described. First, as shown in FIG. 2, the non-volatile memory 11 stores the above-mentioned information 4, 6, and 8 at one-second intervals as one information area... Captured by any of the sampling methods. Therefore, when the vehicle 2 has collided or collided, the information 4, 6, and 8 from the time when the airbag of the airbag device 9 was actuated to a certain time before is stored in the non-volatile memory 11, and the accident processing is performed. Sometimes, this nonvolatile memory 11 can be taken out. By reading out the information 4, 6, 8 in the non-volatile memory 11 by a personal computer or the like, the situation around the vehicle at the time of the accident is clearly reproduced, and the true situation of the accident can be accurately grasped. In addition,
The method of storing information is merely an example, and other methods (not shown) can be used.

[0008]

According to the drive information recording method of the present invention,
With the above configuration, the following effects can be obtained. That is, steering information, vehicle position information, and video information immediately before the occurrence of a vehicle accident can be stored in the non-volatile memory, and the investigation of the cause and crime of the accident becomes much easier and more accurate than in the past.
