Abstract

본 발명은 백업메모리회로에 응용이 가능하게 한 차량충돌방지장치에서의 백업방법 및 장치를 제공하는데있다. 특히 기존의 백업장치는 대표적인 예가 EEPROM 이나 SRAM등의 장치가 있는데 자동차용으로서는 SRAM등은 실제로 EEPROM보다 더 고기이다. 이런 경우에 EEPROM은 그 수명이 문제가 될 수 있으므로 그의 관리 여부에 따라서는 그의 최대 수명까지 사용하는 것이 가능하다. 그런데 기존의 백업장치는 일정한 번지에 집중적으로 라이팅되므로 해당번지가 다른 영역에 비해 훨신 많은 사용 빈도를 갖게 된다. 그리하여 본 발명은 차량충돌방지장치에서 선행차 및 주행정보를 기록하여 주는 경우에 사고분석 및 원인판단에 유용한 역할을 할 수 있다. 이러한 장치에서의 백업용 메모리는 자동차 수명 및 메모리 가격등을 고려하여 선정되므로 적절한 메모리 관리가 요구된다. 특히 본 발명은 메모리를 순차적으로 사용되고 이의 경우에 한 상황의 시작점과 끝점을 표시하는 방법으로 모든 영역을 사용할 수 있게 하여 사고분석 및 원인판단에 유용한 역할을 할 수 있도록 하는데 그 목적이 있다.The present invention provides a backup method and apparatus in a vehicle collision avoidance apparatus that can be applied to a backup memory circuit. Particularly, there are devices such as EEPROM and SRAM, which are typical examples of existing backup devices. SRAM and the like for automobile are actually more meat than EEPROM. In this case, the life of the EEPROM may be a problem, so it is possible to use the EEPROM up to its maximum lifetime depending on its management. However, since the conventional backup device is intensively written in a certain address, the address has a much higher frequency of use than other areas. Therefore, the present invention can play a useful role in accident analysis and cause judgment when the preceding vehicle and driving information are recorded in the vehicle collision avoidance apparatus. Since the backup memory in such a device is selected in consideration of the life span of the vehicle and the memory price, proper memory management is required. Particularly, the present invention aims at enabling the use of all areas in a manner of sequentially using a memory and displaying a starting point and an ending point of a situation in this case, thereby making it possible to play a useful role in accident analysis and cause judgment.
