Patent ID: 8214143

Claim:
A navigation device, comprising: a controller that: obtains information indicating a route of a host vehicle; obtains information indicating a position of the host vehicle; obtains information indicating a form of a number (N) of successive curves (where N is an integer of 2 or more) in front of the host vehicle position on the route; excites a vibrator provided at a position where contact with a driver of the host vehicle is possible in a vibration mode corresponding to the form of the N successive curves when the host vehicle reaches a position at a predetermined distance from the closest curve among the N successive curves; the controller generates a vibration corresponding to an M th (where M is an integer equal to or greater than 1 and equal to or less than N−1) curve near the host vehicle position on the route before generating a vibration corresponding to an (M+1) th curve; and the controller lengthens an interval between the vibration corresponding to the M th curve and the vibration corresponding to the (M+1) th curve in accordance with a longer distance between the M th curve and the (M+1) th curve.
