Title: Vehicle guiding device
Inventor: NAGAI TAKAAKI
IPC: G09B29/10
Filed: 1994-04-15
Abstract: PURPOSE:To indirectly inform traveling guides such as a deviation from a prescribed route and right/left turning and to enable a driver to instantaneously observe the information of the traveling guide without gazing at a screen by changing the display state of the screen by changing the tone or luminance of picture display. CONSTITUTION:A conventional procedure is directly applied to the search of an optimum guide route from a starting point up to a destination and the calculation of a current position of a self-vehicle as it is. A signal processor 3 periodically compares the current position data of a self-vehicle with guide route data stored in an internal route storing part at a prescribed cycle and judges whether the current position is on the guide route or not. When the current position of the self-vehicle is deviated from the guide route, the tone or luminance of the whole screen is changed, so that a driver can instantaneously recognize the deviation from the guide route even when the display screen is not directly observed. Thereby the generation of troubles causing uneasy hearing of voice or caseless observation to the front can be prevented.
