Description

The method for guiding gas station of telematics system

The present invention relates to a method for guiding a gas station of a telematics system, and more particularly, to search for an optimal gas station at a shortest distance while directly entering a path without departing a route within a driving distance that can be driven with a current fuel amount. The present invention relates to a method that can prevent driving in advance due to insufficient fuel amount.

Telematics is a compound word of Telecommunication and Informatics.Telematics system uses wireless communication and GPS technology to provide the driver with location information, real-time traffic information, and vehicle. It refers to a system that can provide various convenience services such as diagnostic services and Internet use.

Such a telematics system basically has a navigation function and performs a road guidance function by reflecting real-time traffic information received from a wireless communication network.

Here, the navigation function detects the location information of the vehicle using GPS information received from a plurality of Global Positioning System (GPS) satellites, and when a destination is input from the vehicle driver, the navigation function searches for an optimal route from the current location to the destination. As a function of performing the navigation function, the vehicle driver may be provided with detailed road situation information even when driving in an unfamiliar area.

In particular, the telematics system provides a function to search for a gas station located at the shortest distance and inform the driver when the fuel level of the vehicle drops below a certain level.

However, since the conventional telematics system provides gas station information only when the fuel warning light is turned on, the current fuel amount is sufficient, but when there is no gas station within the driving distance, it may cause a situation in which driving is impossible due to insufficient fuel. have.

For example, the amount of fuel was sufficient before entering the highway, but it may be impossible to drive to the next rest area due to the high fuel consumption while driving on the highway. This can lead to a situation where the road runs out of fuel and it is impossible to drive to the next gas station. In addition, even when the fuel is exhausted while driving on a country road, even if there is no gas station within the driving distance, a situation where driving is not possible due to lack of fuel may occur.

In addition, since the conventional telematics system simply provides gas station information at the shortest distance without considering the direction of the destination, even though it is a gas station that needs to be detoured through a U-turn on the opposite side of the destination route, Despite driving on a highway, there is a problem of guiding a wrong route such as guiding a gas station on a national road.

In addition, conventional telematics systems do not offer a choice of service stations to suit the driver's preferences (preferred gas station brands, fuel prices, gas discount cards and discount rates, car wash and repair shops, etc.). In addition, there is a problem that can not easily grasp the gas station that can provide other services besides gas.

2 to 4 are diagrams for explaining a gas station guide method of a telematics system according to an embodiment of the present invention.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art may easily implement the technical idea of the present invention.

In the following description of the preferred embodiments of the present invention, when it is determined that the detailed description of the related known technology may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted or briefly described.

1 is a flowchart illustrating a gas station guide method of a telematics system according to an embodiment of the present invention, and FIGS. 2 to 4 are diagrams for describing a gas station guide method of a telematics system according to an embodiment of the present invention.

The flowchart of FIG. 1 will be described with reference to FIGS. 2 to 4.

First, when the telematics system is driven, the driving possible distance rDist is calculated based on the running speed, the fuel amount, and the average fuel consumption ratio (S101).

Here, the average actual fuel ratio is a value obtained by averaging the amount of fuel used to actually drive 1 km, and it is possible to calculate a more accurate running distance based on the average actual fuel ratio.

When the calculation of the driving distance rDist is completed, the calculated driving distance rDist and the current fuel amount are displayed on the screen of the telematics system as shown in FIG. 2 (S103).

Next, if a destination is input from the driver (S105), after searching for a route to the destination (S107), it is checked whether the driving distance rDist is smaller than the distance gDist to the destination (S109).

If the driving distance rDist is smaller than the distance gDist to the destination, it is determined that fueling is necessary while driving because the current fuel amount cannot travel to the destination (S111).

If it is determined that fueling is required while driving, one or more fueling guide points P1 to P10 are set within a driving distance on the searched path as shown in FIG. 3 (S113).

Here, it is determined that fuel replenishment is necessary while setting a fueling guide point at a predetermined interval (for example, 10 km) within the driving distance rDist, or comparing the driving distance rDist and the distance gDist to the destination. The lubrication guide point can be set at the point where

For example, if there is a highway on the searched route, you can set up a tour guide point 1km ahead of the highway ramp, rest area, 1km behind the highway ramp, and pass a forest or paddy field on the searched route. If there is a road, a fueling guide point may be set before and after the entry of the road. In addition, when there is a road causing severe traffic jams on the searched route, a fueling guide point may be set before and after the entry of the road.

Next, the gas stations within the search radius r are searched based on the fueling guide points P1 to P10 set as shown in FIG. 3 (S115) to determine whether one or more gas stations are searched (S117).

If at least one gas station is not found, after resetting the fueling point (S118), the gas station within the search radius r is searched again based on the reset fueling point (S115).

When at least one gas station is searched, as shown in FIG. 3, after checking whether the searched gas station is located at the right side of the driving direction and is directly accessible on the path (Y) (S119), at the fueling point P1 to P10 Check whether the gas station is located at the shortest distance (S121).

Next, in order to reduce the moving distance to the gas station as much as possible, the gas station which is directly accessible on the path and located at the shortest distance is set as the first recommended gas station (S123).

If the searched gas station is located within the search radius r at the fueling point on the route, but is located at the left side of the driving direction and is accessible only through a U-turn, it is set as the second recommended gas station (S120). Even if the gas station Y can be directly entered on the path, but the gas station located at the shortest distance is set as the second recommended gas station (S122).

Next, when the vehicle reaches the fueling guidance point (S125), the fueling time is guided through the voice and the screen (S127), and information of the first recommended gas station is displayed on the screen (S129).

Here, as shown in FIG. 4, gas station information such as a brand of a gas station, a phone number, a distance, and a direct access (X / Y) on a route, a gas price, a discount card, and a car wash / repair station is displayed on the screen. On the screen, a call button for a telephone connection to a corresponding gas station, a previous button and a next button for searching for other gas stations nearby are displayed on the screen.

When the first recommendation gas station is selected from the driver (S131), after guiding the route to the selected first recommended gas station (S137), the gas station guidance is ended.

If the first recommended gas station is not selected from the driver, information of the second recommended gas station is displayed (S133), and if the second recommended gas station is selected from the driver (S135), the route to the selected second recommended gas station is guided. After (S137), the gas station guide is finished.

Here, when displaying the information of the second recommended gas station, the gas station such as the brand of the gas station, the telephone number, the distance, whether or not it can be directly accessed on the route (X / Y), the gas price, the gas discount card, the car wash / maintenance station, etc. While the information is displayed on the screen, a call button for a telephone connection to the corresponding gas station, a previous button and a next button for searching for other gas stations nearby, etc. are displayed on the screen.

Meanwhile, in the present embodiment, the case where the destination is set is mainly described. However, even when the destination is not set, the lubrication guide point is set within the travelable distance, and thus, the driving distance can be directly entered while driving based on the set lubrication guide point. You can search for gas stations located at.

In addition, even when the route to the destination is re-searched due to the departure of the vehicle, it is possible to reset the fueling guide point and search for the gas station located at the shortest distance while being able to enter the path immediately based on the reset fueling guide point. .

That is, in the related art, a gas station close to the driver is notified only when a fueling warning light comes in, so that a situation in which driving is impossible due to insufficient fuel amount may occur. The driver's convenience can be maximized by preventing the inability to drive due to insufficient fuel.

In addition, according to the present invention, the driver can easily check the fuel shortage situation by informing the driver of the available driving distance that can actually travel with the current fuel amount.

In particular, according to the present invention, since it is possible to directly enter on the route without departing the route, the fuel can be filled at the optimum gas station at the shortest distance, thereby reducing unnecessary fuel consumption and shortening the time to reach the destination.

In addition, according to the present invention, since the gas station can be selected according to the driver's preference conditions (gas station brand, fuel price, discount card and discount rate, car wash / maintenance station, etc.), it is possible to reduce the cost and efficiently manage the vehicle. Can be.
