摘要 When in a guide route a vehicle has strayed from a route r1 before passing through an en-route stop W and has moved onto a route r2 selected to lead to a destination E after the en-route stop, if a distance L from a present position of the vehicle to the en-route stop W is below a predetermined value d, travel guidance to the destination E is continued. Conversely, if the distance L from the present position to the en-route stop W is above the predetermined value d, a guide route leading to the destination via the en-route stop W is reset, and the guide route is therefore not switched to the route r2.
