摘要:
A visual travel route indicating apparatus for use in an automotive vehicle. The apparatus comprises a distance sensor for detecting a current distance of travel of the vehicle, a gas rate sensor for detecting a current azimuthal deviation generated during travel of the vehicle, a closed thermostatic chamber for hermetically enclosing the gas rate sensor such that it is isolated from external temperature fluctuations, and a signal processing unit for arithmetically obtaining a current location or point plotted on two-dimensional coordinates per a given unit travel distance from the outputs of the two sensors. A travel path store is provided for storing the thus-obtained data so as to be read out subsequently for a continuous visual indication of a current path of travel or locus of the vehicle on a display unit for visually indicating a continuous path of travel of the vehicle. A manual operating unit is provided for setting and modifying the visual indication pattern to be displayed on the display unit. The closed thermostatic chamber is positively heated to a desired constant temperature level by a suitable heater so that the gas rate sensor may be protected from a possible temperature fluctuation in the external environment.
