Abstract

PURPOSE:To effectively call notes to a driver to obey an actual traffic restriction by sensing a stop of a vehicle and the confirmation of notes and designating a start of a route guiding. CONSTITUTION:A driver observes a display unit 28 near a cab seat to obtain the position of his vehicle itself and following route information. Thus, notes are confirmed. That is, an image storage unit 40, a voice storage unit 32 stores data of image, voice of the notes, and a distance sensor 18 detects presence/ absence of a vehicle stopping state. A note controller 42 designates the unit 28 and a voice controller 30 at a predetermined stage before route guiding, and the unit 28 reads and displays image data from the memory 40. For example, it displays 'always obey actual traffic restriction though displaying a route'. The controller 30 similarly conducts voice guide. After a driver sees and hears notes, the pushes a confirmation switch 19a. When the controller 42 senses the detection of vehicle stop of the sensor 18 and pushing of the switch 19a, it ends the display of the notes and allows starting of route guiding.
