Embodiment Construction

[0031] Specific embodiments regarding the vehicle information recording device according to the present invention will be described with reference to the drawings.

[0032] In this embodiment, it is assumed that the invention is applied to, for example, a image 3 The configuration of the tachograph 100 is shown. However, the invention is not limited to tachographs, but can be applied, for example, to digital tachometers or similar in-vehicle recording devices having the same data recording function.

[0033] image 3 The illustrated tachograph 100 includes an in-vehicle body 10 , a plurality of independent memory cards 21 and 22 , an in-vehicle camera 31 and a speed sensor 32 . In addition, in the main body 10 in the vehicle, a microprocessor (CPU) 11 is set to read and write a memory card 12; interfaces (I / F) 13, 14 and 15, an acceleration (G) sensor 16 and a volatile memory (SDRAM) 17 .

[0034] The microprocessor 11 controls the entire device to realize the function of...

Abstract

Provided is a vehicle information recording device used for periodically or continuously obtaining vehicle information when a specific event happens and automatically recording the obtained information to a preset recording medium. The information recording device comprises a recording medium keeping part configured to simultaneously respectively keeping more than two recording media when each recording medium is in a detachably state and an information writing part for distributing at least one main recording medium selected from a plurality of recording media when the recording medium keeping part keeps a plurality of recording media, distributing at least one of the left recording media as a vice recording medium and automatically guaranteeing an information recording destination area of either or both of the main recording medium and the vice recording medium according to a priority level distributed to the main recording medium and the vice recording medium.

Description

technical field [0001] The present invention relates to an information recording device for a vehicle, which periodically or continuously acquires predetermined information of the vehicle when an emergency occurs, and automatically stores the obtained information in a predetermined storage medium, and more particularly Alternatively, the device can also secure a storage area for recording acquired information. Background technique [0002] In the prior art, a drive recorder or a digital tachometer has been used as a device for automatically recording information acquired on a vehicle. This in-vehicle device is used to automatically acquire data to analyze the cause of traffic accidents or the operating status of business vehicles. [0003] When detecting a large acceleration such as in a traffic accident, the driving recorder basically automatically records and stores data such as images captured by an in-vehicle camera on a non-volatile storage medium such as a memory card...
