Electronic apparatus, guide method, and guide system

An electronic apparatus comprising:

• a communication unit configured to communicate with a server apparatus;
• a receiving unit configured to receive, from the server apparatus, a route to a destination and a lane travel limit zone that is set for each lane and in which a lane change to the route is restricted;
• a calculating unit configured to calculate a position of a vehicle of interest;
• a detecting unit configured to detect a traveling lane on which the vehicle is traveling;
• and
• a guide unit configured to provide a guide concerning the traveling lane according to the position of the vehicle and the traveling lane before the vehicle enters the lane travel limit zone.

A guide method executed in an electronic apparatus that has a control unit, the method comprising:

• a setting step of setting a lane travel limit zone, in which a lane change to a route must not be started, for each lane;
• a vehicle position calculating step of calculating a position of a vehicle of interest;
• a detecting step of detecting a traveling lane on which the vehicle is traveling;
• and
• a guiding step of providing a guide concerning the traveling lane according to the calculated position of the vehicle and the detected traveling lane before the vehicle enters the lane travel limit zone.

A guide system comprising:

• an electronic apparatus comprising:
• a sever-side receiving unit configured to receive a position of a vehicle of interest and a destination from the electronic apparatus, a route calculating unit configured to calculate a route according to the position of the vehicle and the destination,
• a setting unit configured to set a lane travel limit zone, in which a lane change to the route is restricted, for each lane, and
• a transmitting unit configured to transmit the route and the lane travel limit zone to the electronic apparatus;
• and
• an electronic apparatus comprising:
• a position calculating unit configured to calculate the position of the vehicle,
• a detecting unit configured to detect a traveling lane on which the vehicle is traveling,
• a vehicle-side receiving unit configured to receive the route and the lane travel limit zone from the server apparatus, and
• a guiding unit configured to provide a guide concerning the traveling lane according to the position of the vehicle and the traveling lane before the vehicle enters the lane travel limit zone.
