Calculate the standard estimated time required on the map and then add or subtract the gap to show the estimated time required.

Such a conventional navigation system is unable to grasp the current state of communication about the information on the starting point and the major waypoints and the destination destination input by the driver, so a large gap occurs in the estimated estimated time and actual driving time. There is a problem, and there is a problem that a gap occurs in the time required to the destination according to the driving tendency of the driver.

The present invention has been invented to solve the above problems, the object of which is to repeat the time required for driving to the destination for the section and road mainly operated by the driver over a set number of times per day, time zone and then average the learning value By extracting the estimated time required for the operation of the section, and to display the estimated time required for the section when requested by the driver before departure.

In addition, when the driver is traveling on a first road or an undesired route, the driver may not learn about the estimated time required according to the driver's request.

In addition, the repetitive learning provides a time and route guidance that minimizes the required time to the destination, and provides reliability to the data by extracting the expected time required based on the learning result according to the driver's driving tendency.

In addition, it provides guidance of a smooth path for communication by day and time zone without providing external information, and reliability is provided for providing information by accumulating more learning data over time.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As can be seen in Figure 1, the estimated time required device in the vehicle according to the present invention input / output device 10, the navigation device 20, the central processing unit 30, the information storage device 40, ECU ( 50), consisting of a digital clock 60, the input / output device 10 is a touch panel screen input / output device, the driver wants to receive information about the starting point, information about the major waypoints, arrival destination and Various information services are selected and inputted, and the corresponding information selected according to the drive control signal of the CPU 30 is displayed.

The navigation device 20 detects location information of an area currently being operated by communication with a GPS as a vehicle navigation device and provides the information to the central processing unit 30.

The central processing unit 30 repeatedly learns the time required for each day of the week, time zone, and driving tendency from the starting point set by the driver to the main waypoint and arrival destination according to the driving of the vehicle, and then averages the extracted time to extract the actual estimated time required. Based on this, the optimal route is extracted for each day of the week.

The information storage device 40 stores the optimal travel route information extracted for each day of the week, time zone, and estimated time required for each repeating main course section extracted by the central processing unit 30.

The ECU 50 provides the central processing unit 30 with information on whether the vehicle is running according to the detection of information such as the engine speed and the vehicle speed.

The digital clock 60 provides the central processing unit 30 with information on the current date, day of the week, and time according to the driving of the vehicle.

An operation of extracting and indicating an estimated time required from the configuration of the present invention including the above-described function will be described with reference to FIG. 2 as follows.

In the vehicle to which the present invention is applied, when the starting standby state in which the engine start is maintained from the ECU 50 is detected by the central processing unit 30 (S101), the central processing unit 30 detects from the navigation device 20. The location information of the starting point of the current vehicle location is set based on the location information, and the current date, the day of the week, and the time information are set from the digital clock 60 (S102).
