Title:
VEHICLE OPERATING INFORMATION COLLECTING ANALYTICAL SYSTEM
Document Type and Number:
Japanese Patent JP2804956
Kind Code:
B2
Abstract:
PURPOSE: To provide a vehicle operating information collecting analytical system by which a speed graph can be plotted at high speed when it is plotted in various enlargement ratios in an analytical device according to speed data collected in an on-vehicle-device.
CONSTITUTION: In an on vehicle device 3, the first writing-in means 31-1 writes speed compressed data in a portable recording medium 4, and the second writing-in means 31-2 writes speed time series data composed of a maximum value and a minimum value of prescribed time speed in it, respectively. In an analytical device 5, a judging means 51a-1 judges the size of an image screen from time per a single dot of a graph, and a graph creating display means 51a-2 creates and plots the graph by using respectively the speed compressed data when the time per a single dot is short and the speed time series data when the time is long.
