Problems solved by technology

Therefore, when the above-mentioned threshold value is set low, frequent malfunctions due to accidents other than accidents such as emergency braking, emergency steering, and emergency departure, unnecessary dumping, unnecessary power consumption, and flash memory The problem of shortened lifespan
On the other hand, if the threshold value is set too high, there is a possibility that the operation cannot be performed in an important accident
Thus, it is very difficult to properly set the above threshold

Embodiment Construction

[0015] Hereinafter, a detailed description will be given according to an embodiment of the present invention. figure 1 The characteristic functions of the drive recorder 1 described as one embodiment of the present invention are shown in . exist figure 1 In this case, the image acquiring unit 111 stores the image data in which the traveling image is recorded in the first memory in real time. The acceleration acquiring unit 112 measures acceleration during travel. The sound acquisition unit 113 stores the sound data in which the running sound is recorded in the first memory in real time. The acceleration comparison unit 114 compares the acceleration with a threshold in real time to determine whether the acceleration exceeds the threshold. In the judgment by the acceleration comparison unit 114, when the acceleration exceeds the threshold, the voice recognition unit 115 performs voice recognition on the voice data acquired by the voice acquisition unit 113, thereby judging wh...

Abstract

A drive recorder 1 comprises a volatile memory 15, a nonvolatile memory 16, an image collection unit 111 that stores in real-time image data into the volatile memory 15, an acceleration collection unit 112, a sound collection unit 113 that stores in real-time sound data into the volatile memory 15, an acceleration comparison unit 114 that determines in real-time whether the acceleration exceeds a threshold value, a sound recognition unit 115 that determines if the sound data includes an accident sound which is a distinctive sound that is generated at an accident, by performing sound recognition on sound data when the acceleration exceeds the threshold value, and a data transcribe unit 116 that transcribes image data stored in the volatile memory 15 into the nonvolatile memory 16 when it is determined that the accident sound is included in the sound data. Thus, the invention provides a drive recorder which has high recognition precision in recognizing the occurrence or non-occurrence of an accident.

Description

technical field [0001] The present invention relates to a drive recorder and a control method for the drive recorder, and more particularly to a technique for realizing a drive recorder with high recognition accuracy for whether or not an accident has occurred. Background technique [0002] Patent Document 1 discloses a drive recorder capable of recording conditions at the time of an automobile accident. The drive recorder described in Patent Document 1 has the following functions: images captured by a CCD camera or information obtained by various sensors (hereinafter referred to as "accident information") are stored in RAM (Random Access Memory) in real time in advance, The acceleration acquisition unit transfers the accident information to a nonvolatile memory such as a flash memory at a timing when a collision is detected. Here, the accident information is stored in the RAM in this way because the operation speed of the RAM is generally higher than that of the non-volati...
