Abstract
An on-vehicle navigation apparatus 50 includes a current location calculator 21 calculating a current location of an own vehicle, a map information database 2 storing map information including road map data, a driving lane specifying section 23 detecting a lane change in response to an operation signal from a winker and specifying a driving lane of the own vehicle, and a guidance-timing controller 24 detecting a turnoff road ahead of the own vehicle in a traveling direction and conducting turnoff road guidance on a driver at a forward position distanced from the detected turnoff road depending on a location of the specified driving lane of the own vehicle.
Claims9
An on-vehicle navigation apparatus comprising:
- a current location calculator calculating a current location of an own vehicle;
- a map information database storing map information including road map data;
- a driving lane specifying section detecting a lane change in response to an operation signal from a winker and specifying a driving lane on which the own vehicle is traveling;
- and
- a guidance timing controller detecting a turnoff road ahead of the own vehicle in a traveling direction based on the current location of the own vehicle and the road map data, and conducting a turnoff road guidance at a forward position which is between the detected turnoff road and the own vehicle;
- and
- a guidance table determining the forward position for a location of the specified driving lane of the own vehicle, based on a combination of a jam-up status at the turnoff road, and a speed of the own vehicle.
A turnoff road guiding method comprising:
- calculating a current location of an own vehicle;
- detecting a lane change in response to an operation signal from a winker and specifying a driving lane on which the own vehicle is traveling;
- detecting a turnoff road ahead of the own vehicle in a traveling direction based on the current location of the own vehicle and a road map data;
- determining a forward position, which is between the detected turnoff road and the own vehicle, for a location of the specified driving lane of the own vehicle, based on a combination of a jam-up status at the turnoff road, and a speed of the own vehicle;
- and
- conducting a turnoff road guidance on a driver at the forward position.
An on-vehicle navigation apparatus comprising:
- a current location calculation means calculating a current location of an own vehicle;
- a map information storage means storing map information including road map data;
- a driving lane specifying means detecting a lane change in response to an operation signal from a winker and specifying a driving lane on which the own vehicle is traveling;
- and
- guidance timing control means detecting a turnoff road ahead of the own vehicle in a traveling direction based on the current location of the own vehicle and the road map data, and conducting a turnoff road guidance at a forward position which is between the detected turnoff road and the own vehicle;
- and
- a guidance table determining the forward position for a location of the specified driving lane of the own vehicle, based on a jam-up status at the turnoff road, and a speed of the own vehicle.
