Abstract
A vehicle navigation system disposed in a vehicle executes a route guidance function that calculates a first route by prioritizing a special lane over a normal lane as a route calculation condition and performs route guidance when a special lane use option is turned on. A determination unit determines whether the vehicle is traveling in a parallel route section in which the special lane and normal lane are in parallel. If the vehicle is traveling in the parallel route section, a second route calculation unit calculates a second route towards the destination based on an assumption that the vehicle is traveling in the normal lane. In addition, a second route guidance unit outputs a second guidance phrase at a second guidance point, such that the second guidance phrase includes a conditional phrase that conveys that the vehicle is not in the special lane.
