摘要:
An apparatus for use in an automotive vehicle for visually indicating the travel route thereof. A current travel route of the vehicle is arithmetically obtained in terms of two-dimensional coordinates for a unit travel distance of the vehicle on the basis of outputs from a travel distance detecting unit and a gas rate sensor. The thus-obtained locational data on the current location of the vehicle, varying from time to time, is stored in sequence, and the current travel path of the vehicle is continuously visually indicated. A timer unit is provided for starting the supply of power to the gas rate sensor a sufficient amount of time prior to starting the vehicle to permit the sensor to reach a stable working temperature in advance.
