Abstract

A system and method of estimating an available driving distance of an electric vehicle are provided. The method includes dividing a road into sections and receiving driving information from a vehicle traveling through each of the sections. Fuel efficiency data of the corresponding section is generated and vehicle condition information, and departure point and destination information is received from the target vehicle. Additionally, the method includes receiving real time meteorological information and road traffic situation information for each of the sections and reflecting the vehicle condition information of the target vehicle, the meteorological information and the road traffic situation information in the fuel efficiency data generated for each of the sections of the road from the departure point toward the destination. Estimated fuel efficiency and an estimated available driving distance of the target vehicle are then determined to be provided to vehicle driver.

First claim

What is claimed is:

1. A method of estimating an available driving distance of an electric vehicle, comprising:
dividing, by a telematics server, a road into a plurality of sections;
receiving, by the telematics server, driving information from an arbitrary vehicle traveling through each of the sections;
generating, by the telematics server, fuel efficiency data of the corresponding section based on the driving information;
receiving, by the telematics server, vehicle condition information, and departure point and destination information from a target vehicle;
receiving, by the telematics server, real time meteorological information and road traffic situation information for each of the sections of the road from the departure point to the destination;
reflecting, by the telematics server, the vehicle condition information of the target vehicle, the meteorological information and the road traffic situation information in the fuel efficiency data generated for each of the sections of the road from the departure point to the destination; and
calculating, by the telematics server, estimated fuel efficiency and an estimated available driving distance of the target vehicle,
wherein the driving information received from each arbitrary vehicle traveling through the sections includes: a battery consumption rate at which a battery of the arbitrary vehicle is consumed while traveling through the corresponding section, an ambient temperature when the arbitrary vehicle drives through the corresponding section, an average driving speed in the corresponding section, information indicating whether an eco-mode of the arbitrary vehicle is engaged, information indicating whether headlamps of the arbitrary vehicle are turned on, and information indicating whether wipers of the arbitrary vehicle are turned on.

2. The method according to claim 1 , wherein the vehicle condition information transmitted from the target vehicle includes a battery condition information of the target vehicle and information regarding whether an electric apparatus load is being used, and is transmitted to the telematics server.

3. The method according to claim 1 , wherein the calculating of the estimated fuel efficiency and the estimated available driving distance of the target vehicle comprises:
compensating for the fuel efficiency and the available driving distance of the vehicle traveling in each of the sections of the road from the departure point to the destination, by updating the vehicle condition information of the target vehicle, the meteorological information and the road traffic situation information on a preset cycle.

4. The method according to claim 1 , wherein in the receiving of the real time meteorological information and the road traffic situation information, before the meteorological information and the road traffic situation information are received, average values of meteorological information and road traffic situation information pre-stored in the telematics server are used.

5. The method according to claim 1 , wherein in the calculating of the fuel efficiency, when the number of initial fuel efficiency data for each of the sections is less than a preset number of data, initial set data, data of a section adjacent to the corresponding section, or combination data of the corresponding section and the adjacent section is used.

6. The method according to claim 1 , further comprising:
after the calculating of the available driving distance, displaying, by a telematics terminal of the vehicle, the calculated available driving distance on a map as an available driving range.

7. A system for estimating an available driving distance of an electric vehicle using a telematics system in which a telematics terminal of the electric vehicle and a telematics server are interlocked with each other, the system comprising:
a telematics server configured to divide a road into a plurality of sections, receive driving information from an arbitrary vehicle traveling through each of the sections, and generate fuel efficiency data of the corresponding section based on the driving information;
a route searching unit configured to search for the fuel efficiency data stored in a database for the sections of the road toward a destination set in a telematics terminal of a target vehicle;
a communication unit configured to receive vehicle condition information, and departure point and destination information that are transmitted from the target vehicle, and receive real time meteorological information and road traffic situation information for each of the sections of the road from the departure point toward the destination; and
a calculation unit configured to reflect the vehicle condition information of the target vehicle, the meteorological information and the road traffic situation information received from the communication unit, in the fuel efficiency data generated for each of the sections of the road from the departure point toward the destination, and calculate estimated fuel efficiency and an estimated available driving distance of the target vehicle,
wherein the driving information received from each arbitrary vehicle traveling through the sections includes: a battery consumption rate at which a battery of the arbitrary vehicle is consumed while traveling through the corresponding section, an ambient temperature when the arbitrary vehicle drives through the corresponding section, an average driving speed in the corresponding section, information indicating whether an eco-mode of the arbitrary vehicle is engaged, information indicating whether headlamps of the arbitrary vehicle are turned on, and information indicating whether wipers of the arbitrary vehicle are turned on.

8. The system according to claim 7 , wherein the vehicle condition information transmitted from the target vehicle includes a battery condition information of the target vehicle and information regarding whether an electric apparatus load is being used, and is transmitted to the telematics server.

9. The system according to claim 7 , wherein in the calculation of the estimated fuel efficiency and the estimated available driving distance of the target vehicle, the fuel efficiency and the available driving distance of the vehicle traveling in each of the sections of the road from the departure point to the destination is compensated for by updating the vehicle condition information of the target vehicle, the meteorological information and the road traffic situation information on a preset cycle.

10. The system according to claim 7 , wherein before the meteorological information and the road traffic situation information are received, average values of meteorological information and road traffic situation information pre-stored in the telematics server are used.

11. The system according to claim 7 , wherein when the calculation unit is configured to calculate the fuel efficiency at an initial stage, when the number of initial fuel efficiency data for each of the sections is less than a preset number of data, initial set data, data of a section adjacent to the corresponding section, or combination data of the corresponding section and the adjacent section is used.

12. The system according to claim 7 , wherein the available driving distance calculated by the calculation unit is displayed and provided on a map as an available driving range by the telematics terminal of the target vehicle.

13. A non-transitory computer readable medium containing program instructions executed by a processor for estimating an available driving distance of an electric vehicle, the non-transitory computer readable medium comprising:
