Abstract

A traffic information providing system includes a traffic information collector configured to collect information on traffic flow. A traffic information generator is configured to detect a speed change point at which an average vehicle speed on a road changes based on the information on the traffic flow and to generate traffic information including position information on the speed change point and a target speed after a vehicle passes the speed change point. A traffic information provider is configured to transmit the traffic information to a vehicle controller for automatically controlling acceleration or deceleration of the vehicle based on the target speed.

Claims

1. A traffic information providing system comprising:

a traffic information collector configured to collect information on traffic flow;

a traffic information generator configured to detect a speed change point at which an average vehicle speed on a road changes based on the information on the traffic flow and to generate traffic information including position information on the speed change point and a target speed after a vehicle passes the speed change point; and

a traffic information provider configured to transmit the traffic information to a vehicle controller for automatically controlling acceleration or deceleration of the vehicle based on the target speed,

wherein the traffic information generator detects a coasting section at which coasting is possible based on the information on the traffic flow and map data, and generates the traffic information to include the position information on the coasting section.

2. The system of claim 1, wherein the traffic information generator calculates the target speed based on the average vehicle speed in a constant speed section after passing the speed change point.

3. The system of claim 1, wherein the traffic information further includes a time period for reaching the target speed.

4. The system of claim 3, wherein the traffic information generator calculates an acceleration time period in an acceleration section for reaching the target speed without hard acceleration as a reaching time period.

5. The system of claim 3, wherein the traffic information generator calculates a reaching time period to obtain a safe distance corresponding to the target speed in a deceleration section.

6. The system of claim 1, wherein the traffic information provider receives a present position of the vehicle from the vehicle controller, and transmits the traffic information on surrounding roads selected based on the present position of the vehicle to the vehicle controller.

7. A method for providing traffic information using a traffic information providing system, the method comprising steps of:

collecting, by a traffic information collector, information on traffic flow;

detecting, by a traffic information generator, a speed change point at which an average vehicle speed on a road changes based on the information on the traffic flow;

generating, by a traffic information generator, traffic information including position information on the speed change point and a target speed after a vehicle passes the speed change point;

transmitting, by a traffic information provider, the traffic information to a vehicle controller for automatically controlling acceleration or deceleration of the vehicle based on the target speed; and

detecting a coasting section at which coasting is possible based on the information on the traffic flow and map data,

wherein the traffic information further includes the position information on the coasting section.

8. The method of claim 7, further comprising a step of calculating the target speed based on an average vehicle speed in a constant speed section after passing through the speed change point.

9. The method of claim 7, wherein the traffic information further includes a time period for reaching the target speed.

10. The method of claim 9, further comprising a step of calculating an acceleration time period in an acceleration section for reaching the target speed without hard acceleration as a reaching time period.

11. The method of claim 9, further comprising calculating a reaching time period to obtain a safe distance corresponding to the target speed in a deceleration section.

12. The method of claim 7, further comprising a step of receiving a present position of the vehicle from the vehicle controller,

wherein the step of transmitting the traffic information includes transmitting the traffic information on surrounding roads selected based on the present position of the vehicle to the vehicle controller.
