Apparatus for visually indicating continuous travel route of a vehicle
摘要:
A vehicle travel route indicating apparatus comprising detectors for detecting current travel distance and bearing of a vehicle, respectively; a signal processor for obtaining a current location of the vehicle on two-dimensional coordinates; a memory for storing continuous locational information; a display for indicating a path of travel and a sense mark; and a manual selector for optionally changing the manner of visual indication settings. With such simplified construction, the driver of the vehicle can incessantly determine the status of travel of the vehicle in terms of both distance and bearing aspects during the travel by following the first-hand information displayed at his seat with greater ease and reliability.
