DEVICE FOR NAVIGATING A MOTOR VEHICLE AND A METHOD OF NAVIGATING THE SAME
First Claim
1. A method of navigating a motor vehicle with reference to current traffic conditions in an area, comprising:
- transmitting signals by a signal transceiver to a navigation unit in the motor vehicle, the signals including at least one selected from the group consisting of (a) current velocity information of sampling vehicles in the area and (b) current positional information of the sampling vehicles in the area;
computing, by the navigation unit, a reference value as a number proportional to traffic incident flow of at least one vehicle at a specific time based upon at least one of the current velocity information and the current positional information;
identifying a traffic incident, by the navigation unit, based on data computations made by the navigation unit; and
issuing, by the navigation unit, a warning of a traffic incident in the area if the reference value is smaller than a predetermined value that represents at least one of historical velocity information and historical positional information associated with the area in a normal traffic condition.

Abstract
A method and system for navigation of a motor vehicle with reference to current traffic conditions in an area are presented. The navigation of the motor vehicle includes transmitting signals by a signal transceiver to a navigation unit in the motor vehicle, the signals include at least (a) current velocity information of sampling vehicles in the area or (b) current positional information of the sampling vehicles in the area; computing by the navigation unit at least one of the current velocity information and the current positional information to provide a reference value; and issuing by the navigation unit a warning of a traffic incident in the area if the reference value is smaller than a predetermined value.

16. A motor vehicle navigating system, comprising:
-
a signal transceiver that is configured to transmit signals to a motor vehicle, the signals including at least one selected from the group consisting of (a) current velocity information of sampling vehicles in the area and (b) current positional information of the sampling vehicles in the area; and a navigation unit connected to the motor vehicle, which comprises a non-transitory computer-readable medium that stores data for implementing; computing, by the navigation unit, a reference value as a number proportional to traffic incident flow of at least one vehicle at a specific time based upon at least one of the current velocity information and the current positional information; identifying a traffic incident, by the navigation unit, based on data computations made by the navigation unit; and issuing a warning of a traffic incident in the area if the reference value is smaller than a predetermined value that represents at least one of historical velocity information and historical positional information associated with the area in a normal traffic condition. - View Dependent Claims (17, 18, 19, 20)
