Navigation system and navigation method
First Claim
1. A navigation system comprising:
- a position determination unit configured to determine a position of a vehicle;
a route calculation unit configured to calculate a driving route;
a maneuver determination unit configured to determine a driving maneuver in accordance with the driving route;
means for outputting indications associated with the driving maneuver that alert a driver of the vehicle;
a plurality of sensors configured to detect respective values of a plurality of parameters relating to an operational state of the vehicle; and
a potential wrong way driving unit configured to detect a potential wrong way driving situation and to generate an indication at the means for outputting associated with the potential wrong way driving situation, the potential wrong way driving unit including;
a set value determination unit configured to determine set values of the plurality of parameters indicative of a potential wrong way driving situation associated with the determined driving maneuver, the plurality of parameters including a relative position of the vehicle to at least one location of the calculated driving route and at least one other parameter;
a comparator configured to compare the detected values to the respective determined set values, where at least one of the detected values and determined set values compared is the relative position of the vehicle to the at least one location; and
a judging unit configured to judge the result of the comparison and to detect the potential wrong way driving situation.
