As described above, when a vehicle is connected to the telematics center through route request information or output of a warning based on deduction of a reference point, the telematics center may receive driving information of the corresponding vehicle (S610). The driving information may include information on a vehicle position, a set reference point, the current reference point, a number of instances of point-deduction behaviors, and the like.

Based on the received driving information, the reference point setting unit 430 may update the reference point for each road and each time period (S620A) and the point-deduction standard setting unit 440 may update the point-deduction standard information for each road and each time period (S620B).

Hereinafter, an update procedure of the reference point setting unit 430 and the point-deduction standard setting unit 440 will be described in more detail.

First, the update operation S620A of the reference point setting unit 430 will be described.

The aforementioned driving information may be received from a plurality of vehicles, and driving information items received from the respective vehicles are independent from each other statistically, and thus when the driving information items of all the vehicles is analyzed, the driving information items generally follow a Gaussian distribution. Such a Gaussian distribution is shown in FIG. 6. FIG. 6 shows a Gaussian distribution applied to another embodiment of the present invention.
