Claims (1)

[Scope of utility model registration request] A travel distance detection section 1 that detects the travel distance of the vehicle, a traveling direction detection section 2 that detects the traveling direction of the vehicle, a first storage section 5 that stores map information, and coordinates corresponding to the trajectory traveled by the vehicle. and a second storage unit 6 that stores current position indicators 5a of multiple types of vehicles, a control unit 3 that outputs a current position indicator switching signal every time a unit physical quantity related to traveling of the vehicle changes or progresses, and a display 7. , and a central processing unit 4, and the central processing unit 4 reads map information of the area including the travel start point from the first storage unit 5 based on an instruction from the outside before traveling, and stores the map information. The information is displayed on the display 7, the travel start point is displayed in correspondence with the positional relationship on the map information displayed on the display 7, and after the travel, the travel distance detection unit 1 and the traveling direction are displayed. The current position of the vehicle is calculated based on the output signal from the detection unit 2, and the current position is displayed on the map information displayed on the display 7 in association with the positional relationship. The positional relationship is stored in the second storage section 6, and each time a current position index switching signal is supplied from the control section 3, an index 5a indicating the current position of the vehicle is stored from the second storage section 6. A travel guidance device for a vehicle, characterized in that the current position 5a of the vehicle on the displayed map information is selectively selected and displayed.
