Abstract

A system for providing driving information of an electric includes a telematics terminal configured to collect driver information, internal state information, and external environment information, and transmitting the collected driver information, internal state information, and external environment information. A path information server is configured to transmit road information and traffic information to the outside. A telematics server is configured to accumulate information received from the telematics terminal and the path information server, calculate a driving pattern of a first driver based on the accumulated information, calculate one or more candidate paths based on the driving pattern, and transmit the calculated one or more candidate paths to the telematics terminal.

Claims

1. A system for providing driving information of an electric vehicle, the system comprising:

a telematics terminal configured to

collect driver information, internal state information, and external environment information, and

transmitting the collected driver information, internal state information, and external environment information to the outside;

a path information server configured to transmit road information and traffic information to the outside; and

a telematics server configured to

accumulate information received from the telematics terminal and the path information server,

calculate a driving pattern of a first driver based on the accumulated information,

calculate one or more candidate paths based on the driving pattern, and

transmit the calculated one or more candidate paths to the telematics terminal,

wherein the system is interlocked with the telematics terminal by the telematics terminal, and

wherein the telematics server includes;

a server communicator configured to

receive the driver information, the internal state information, and the external environment information, and

transmit driving related information to the outside;

a database configured to store the received information;

a driving pattern calculator configured to calculate the driving pattern of the first driver based on the information accumulated in the database;

a drivable distance calculator configured to calculate a drivable distance decrement based on the calculated driving pattern and information about a second driver accumulated in the database; and

a path calculator configured to calculate a shortest time path, a shortest distance path, and an optimum path in which the drivable distance decrement is minimal.

2. The system of claim 1, wherein the driver information includes driver personal information, vehicle model information, driving distance information, and driving time information.

3. The system of claim 1, wherein the internal state information includes vehicle speed information, acceleration/deceleration information, battery information, motor load information, and maintenance history information, and the external environment information includes position and weather information.

4. The system of claim 1, wherein in a case where a destination is transmitted from the telematics terminal, the telematics server

searches for the driving pattern of the first driver and information matched with the driving pattern based on the information accumulated in the database, and

calculates the drivable distance decrement based on the driving pattern of the first driver and the information about the second driver.

5. The system of claim 4, wherein the telematics server calculates an optimum path in which the drivable distance decrement is minimal among the one or more candidate paths.

6. The system of claim 5, wherein if driving to the destination is impossible in a current battery charging state based on the information received from the telematics terminal and the searched driving pattern of the first driver and information matched with the driving pattern, the telematics server calculates a path having minimum battery consumption and an electricity charging station.

7. The system of claim 5, wherein

the telematics server transmits a shortest time path, a shortest distance path, and the optimum path to the telematics terminal, and

the telematics terminal

displays a desired path selected among the shortest time path, the shortest distance path, and the optimum path, and

guides a drivable distance decrement of the desired path.

8. The system of claim 1, wherein the telematics terminal includes:

an information collector configured to collect the driver information, the internal state information, and the external environment information;

a terminal communicator configured to

transmit the collected information and a destination to the telematics server through wireless communication, and

receive the one or more candidate paths and the drivable distance decrement;

a display configured to display a selected desired path and the drivable distance decrement expected in a case where the first driver drives the desired path; and

a terminal controller configured to

transmit the collected information, and

control the information collector, the terminal communicator, and the display to display the desired path.

9. A method of providing driving information through interworking with a telematics terminal installed in an electric vehicle by a telematics server, the method comprising:

receiving a destination from a telematics terminal;

searching for a driving pattern of a first driver stored in a database;

searching for driver information, internal state information, and external environment information matched with the driving pattern stored in the database;

calculating a drivable distance decrement based on the searched driving pattern;

calculating one or more candidate paths including an optimum path in which the calculated drivable distance decrement is minimal; and

transmitting the calculated one or more candidate paths to the telematics terminal,

wherein the calculating of the one or more candidate paths including the optimum path in which the calculated drivable distance decrement is minimal, the calculating includes;

calculating a shortest time path in which a time to arrive a destination is minimal;

calculating a shortest distance path in which a driving distance to the destination is minimal; and

calculating a path having minimum battery consumption to the destination and an electricity charging station.

10. The method of claim 9, wherein the driving pattern is calculated based on the driver information, the internal state information, and the external environment information accumulated in the database.
