System and method for estimating available driving distance of electric vehicle

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.

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:

• program instructions that 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;
• program instructions that receive vehicle condition information, and departure point and destination information from a target vehicle;
• program instructions that receive real time meteorological information and road traffic situation information for each of the sections of the road from the departure point to the destination;
• and
• program instructions that reflect 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 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.
