PURPOSE:To guide a way positively by providing a position measuring means, a storage means, a control means and a display means, and further providing two-stage selecting means for selecting a mode for storing the information of a going way, a mode for computing/displaying the information of a return way and a mode for computing/displaying information into an optional position. CONSTITUTION:The memory mode of a going way is selected by opening a first selector switch 4, and the position information of the vehicle going way is stored into a memory 34. The regeneration mode of a return way is then selected by closing the switch 4. In a normal mode in the regeneration mode, the information of the return way is computed from the stored position information, whereas in a look-ahead mode in the regeneration mode, the information of the return way is computed in an optional place from the position information of an optional return way assigned by a second selector switch 5. A display device 6 then displays its computed result. The improvement of driving safety can be thus expected with simple switching operation. |
