VEHICLE TRACKING DETECTION AND ALARM METHOD AND NAVIGATION DEVICE USING THE METHOD
First Claim
1. A tracking detection and alarm method of a navigation device of a vehicle, the method comprising:
- retrieving a plurality of positioning data points, generated based on locations of the vehicle, from a navigation module of the navigation device;
calculating and generating a plurality of deflections and a plurality of average speeds that corresponds to the position data points;
calculating and generating a plurality of maximum deflections according to the average speeds;
when a deflection of a positioning data point is greater than a maximum deflection thereof, adding one to a frequency of unsafe driving; and
when the frequency of unsafe driving is greater than a preset threshold value, sending out an unsafe driving alarm.

Abstract
A tracking detection and alarm method which is applied to a navigation device use a number of positioning data points retrieved from a navigation module of the navigation device. A number of deflections and a number of average speeds that correspond to the position data points are calculated and generated. A number of maximum deflections are calculated and generated according to the average speeds. When a deflection of a positioning data point is greater than a maximum safe deflection thereof, one is added to a frequency of unsafe driving instances. When the frequency of unsafe driving instances is greater than a preset threshold value, an unsafe driving alarm is activated.
