Claims

[Scope of Utility Model Registration Request] (1) A map meter that measures the distance on a map corresponding to the route to be traveled and outputs an electrical signal corresponding to the distance, and inputs right and left turn information for each right and left turn point. and a right/left turn information input means for storing distance information for each right/left turn point based on the output signal of the map meter, and for corresponding the right/left turn information input by the right/left turn information input means to the distance information. a gyro device that detects at least the angular velocity generated as the vehicle turns left or right and outputs a response signal based on the angular velocity; and inputs a pulse signal synchronized with the rotation of the wheels from the vehicle. a signal input means for reading the distance information between the corresponding right and left turn points from the information storage means based on a travel start signal at the starting point of the vehicle travel or a response signal of the wheel device; A vehicle is detachably equipped with: a distance counting means for subtracting counting based on a pulse signal synchronized with rotation; and a display means for displaying the counting result of the distance counting means and right/left turn information corresponding to the distance information. A vehicle travel guide device characterized by: (2) A claim characterized in that the information storage means includes an electrically rewritable volatile memory element and a storage battery that constantly supplies power to the memory element.
(1) The vehicle travel guide device described in (1). (3) The vehicle travel guide device according to claim (1), wherein the information storage means includes an electrically rewritable nonvolatile storage element.
