Abstract
A vehicle navigation apparatus includes: a vehicle position information obtaining unit detecting a vehicle position; a special section detecting unit detecting a special section from a guidance route ahead of the vehicle position; a leading lane shift detecting unit detecting a shift of the vehicle from a main line to the leading lane in the special section; and a branch guiding unit conducting branch guidance for a branch point with a leading lane and conducting, in response to the detection of the shift of the vehicle into the leading lane detected by the leading lane shift detecting unit, travel guidance for a branch path.
Claims10
A vehicle navigation apparatus, comprising:
- a vehicle position information obtaining unit that detects a vehicle position;
- a guidance route calculating unit that calculates a guidance route based on the vehicle position and a set destination;
- a special section detecting unit that detects a special section based on the guidance route ahead of the vehicle position, the special section having a branch point with a leading lane through which a branch path diverges from a main line, the leading lane only permitting travel to the branch path;
- a leading lane shift detecting unit that detects a shift of the vehicle from the main line to the leading lane in the special section;
- and
- a branch guiding unit that:
- performs branch guidance for the branch point with the leading lane when the special section is detected by the special detection section detecting unit;
- and
- performs, in response to the detection of the shift of the vehicle into the leading lane detected by the leading lane shift detecting unit, travel guidance for a next branch point located on the branch path further along the guidance route.
A non-transitory computer-readable storage medium storing a computer-executable vehicle navigation program, the program comprising:
- instructions for detecting a vehicle position;
- instructions for calculating a guidance route based on the vehicle position and a set destination;
- instructions for detecting a special section based on the guidance route ahead of the vehicle position, the special section having a branch point with a leading lane through which a branch path diverges from a main line, the leading lane only permitting travel to the branch path;
- instructions for detecting a shift of the vehicle from the main line to the leading lane in the special section;
- instructions for performing branch guidance for the branch point with the leading lane when the special section is detected;
- and
- instructions for performing, in response to the detection of the shift of the vehicle into the leading lane, travel guidance for a next branch point located on the branch path further along the guidance route.
A vehicle navigation method, comprising:
- detecting a vehicle position;
- calculating a guidance route based on the vehicle position and a set destination;
- detecting a special section based on the guidance route ahead of the vehicle position, the special section having a branch point with a leading lane through which a branch path diverges from a main line, the leading lane only permitting travel to the branch path;
- detecting a shift of the vehicle from the main line to the leading lane in the special section;
- performing branch guidance for the branch point with the leading lane when the special section is detected;
- and
- performing, in response to the detection of the shift of the vehicle into the leading lane, travel guidance for a next branch point located on the branch path further along the guidance route.
