Abstract
A route guiding method for an in-vehicle navigation device. To guide a vehicle to a destination by an optimum route, it is determined whether the vehicle is on track within a predetermined intersection range based on route guidance data received from a traffic information center via a mobile communication network. If the vehicle is on track within the intersection range, it is determined whether the vehicle is in a free run state according to predetermined free run conditions to prevent a preliminary route guidance message that is confusing to a driver in the free run state. According to the determination result, the preliminary route guidance message is selectively provided.

A route guiding method for an in-vehicle navigation device, comprising the steps of:
- determining whether a vehicle is on track within a predetermined intersection range based on route guidance data received from a traffic information center via a mobile communication network;
- determining whether the vehicle is in a free run state according to predetermined free run conditions to prevent a preliminary route guidance message that is confusing to a driver of the vehicle in the free run state, if the vehicle is on track within the intersection range;
- and
- selectively providing the preliminary route guidance message according to the determined result.
A route guiding method for an in-vehicle navigation device, comprising the steps of:
- determining whether a vehicle is within a predetermined intersection range based on route guidance data received from a traffic information center via a mobile communication system;
- determining whether the vehicle is on track based on calculated route information contained in the route guidance data, if the vehicle is within the intersection range;
- determining whether the vehicle is in a free run state according to predetermined free run conditions to prevent a preliminary route guidance message that is confusing to a driver of the vehicle in the free run state, if the vehicle is on track in the calculated route;
- discontinuing provision of the preliminary route guidance message in the free run state;
- and
- providing the preliminary route guidance message before the vehicle reaches a next intersection if the free run conditions are not satisfied.
