Abstract: A navigation device provides route guidance only by voice guidance even if route guidance by a display screen is impossible. A navigation device displays on a display device a navigation screen including a map about a current position. The display device can enter a no-display state. In the navigation device, regardless of the state of the navigation screen, a route guidance method is performed. More particularly, in the display state, a guidance route is determined by a normal mode and route guidance is performed by both voice and display. In the no-display state, a guidance route including fewer movement methods is determined and route guidance is made only by voice guidance. Thus, in the no-display state where the navigation screen is not displayed, a guidance route is determined so as to enable route guidance only by voice.

Abstract: When a vehicle travels along a guidance path and approaches an intersection, a vehicle navigation system determines crossing points between a circle having its center set to the intersection and a predetermined radius, and an approach link and an exit link for the intersection. The system also sets a direction connecting the crossing point for the approach link and the intersection as an approach direction, and sets a direction connecting the intersection and the crossing point for the exit link as an exit direction. The system determines a traveling direction at the intersection based on an angular difference between the approach direction and the exit direction, and determines a display position of the intersection on a screen. Further, an enlarged intersection image is drawn such that the approach direction is aligned with a 12 o'clock direction on the screen.

A navigational device sends travel route related information of a travel route set by the user to the server. The server sends detailed guidance information of the warning point included in the traveling route set in the navigational device to the navigational device. Upon arrival at the warning point, the navigational device notifies detailed guidance, and upon arrival at an existing guidance point, the navigational device notifies existing guidance.

Abstract: In a vehicular navigation system, it is determined that a branching point is present along a guidance route within a given distance from a guidance intersection. It is then determined that approaching the branching point by using a natural exit lane results in entering a road that is not included in the guidance route, wherein the natural exit lane is included in an exit road exiting from the guidance intersection and exits naturally from the guidance intersection along the guidance route. Before entering the guidance intersection, it is suggested that a lane change be required after passing through the guidance intersection. Thus, in a case that a lane change is needed just after passing through the guidance intersection, a driver can respond with a sufficient time period.
