Abstract

A method for navigation of a vehicle using a navigation system with stored map data having road segments comprising determining a current road segment and a current position of the vehicle in the current road segment and receiving a user input command. The method determines a destination in the current road segment or in another road segment of a parallel lane of the current road segment, the determining being initiated by the input. A route from the current position to the destination is calculated in the absence of a turn-around maneuver within the current road segment.

Claims

1. A method for navigation of a vehicle using a navigation system with stored map data having road segments comprising the steps:

determining a current road segment and a current position of the vehicle in the current road segment;

receiving a user input command;

determining a destination in the current road segment or in another road segment of a parallel lane of the current road segment, the determining being initiated by the input; and

calculating a route from the current position to the destination in the absence of a turn-around maneuver within the current road segment.

2. The method of claim 1, wherein the destination is calculated by adding an offset (Δ

x) to the current position.

3. The method of claim 1, wherein the route is selected from calculated different routes by the input.

4. The method of claim 1, wherein the route is changed, in that a driving maneuver is allowed or not allowed by the input for calculating the route.

5. The method of claim 1, wherein the step of receiving includes receiving up to two input commands.

6. The method of claim 1,

wherein a first direction of the vehicle'"'"'s motion within the current road segment is determined;

wherein the input is associated with a second direction; and

wherein the second direction and the first direction are different.

7. The method of claim 1,

wherein a first direction of the vehicle'"'"'s motion within the current road segment is determined;

wherein the input command is associated with a second direction; and

wherein the second direction is set opposite to the first direction, when the current road segment is not a one-way street, and the second direction corresponds to the first direction, when the current road segment is a one-way street.

8. The method of claim 1, wherein the step of determining of the destination is deactivated or an information item is output, when the current road segment is a one-way street.

9. A system for navigation, comprising:

an input unit that receives user input commands;

an arithmetic logic unit connectable to a data base having stored map data with road segments;

wherein the arithmetic logic unit calculates a route to a destination based on the input command,

wherein the arithmetic logic unit determines a current road segment and a current position in the current road segment;

wherein the arithmetic logic unit determines the destination in the current road segment or in another road segment of a parallel lane of the current road segment; and

wherein the arithmetic logic unit calculates the route from the current position to the destination without a turn-around maneuver within the current road segment.
