Vehicle digital movement data recording apparatus

U.S. Patent Number: 5379219

Abstract: The main purpose of a vehicle digital movement data recording apparatus according to the present invention is to cope with a shortage of the memory space in the digital movement data recording area of an external record medium. For completing this objective, the recording apparatus, includes a digital movement data generating device for supervising the moving state of the vehicle and producing the digital movement data thereof. A storage device records the digital movement data produced by the digital movement data generating device onto a digital movement data recording area of an external record medium which can be loaded into and unloaded from the recording apparatus. A detecting device detects the situation that there is no more available space for recording the digital movement data the data recording area of the external record medium. When the detecting device detects that there is no available space for recording the movement data in the digital movement data recording area of the external record medium, the storage device records such data as travel starting time, terminating time and a travel distance of the vehicle of each vehicle movement in a memory shortage compensation area provide in an optional recording area of the external record medium.
