Abstract

Provided are a system and method for managing dangerous driving index for vehicle. The system includes a driver'"'"'s vehicle driving trajectory generator configured to generate a driver'"'"'s vehicle driving trajectory, based on driver'"'"'s vehicle driving information input from an internal sensor which senses a driving situation of the driver'"'"'s vehicle, a peripheral vehicle trajectory generator configured to generate a peripheral vehicle trajectory, based on ambient environment information input from an external sensor which senses the driving situation of the driver'"'"'s vehicle, a trajectory load calculator configured to calculate a trajectory load representing a comparison result which is obtained by comparing a predetermined threshold value with a trajectory distance which is a difference between the peripheral vehicle trajectory and the driver'"'"'s vehicle driving trajectory, and a dangerous index manager configured to generate a dangerous driving index corresponding to the calculated trajectory load.

Claims

1. A system for managing dangerous driving index for vehicle, the system comprising:

a driver'"'"'s vehicle driving trajectory generator configured to generate a driver'"'"'s vehicle driving trajectory, based on driver'"'"'s vehicle driving information input from an internal sensor which senses a driving situation of the driver'"'"'s vehicle;

a peripheral vehicle trajectory generator configured to generate a peripheral vehicle trajectory, based on ambient environment information input from an external sensor which senses the driving situation of the driver'"'"'s vehicle;

a trajectory load calculator configured to calculate a trajectory load representing a comparison result which is obtained by comparing a predetermined threshold value with a trajectory distance which is a difference between the peripheral vehicle trajectory and the driver'"'"'s vehicle driving trajectory; and

a dangerous index manager configured to generate a dangerous driving index corresponding to the calculated trajectory load.

2. The system of claim 1, further comprising a peripheral vehicle load calculator configured to calculate a peripheral vehicle load, based on number of peripheral vehicles included in the ambient environment information and whether the peripheral vehicles change lanes.

3. The system of claim 2, wherein the peripheral vehicle load calculator divides a plurality of dangerous sections with respect to the driver'"'"'s vehicle, based on a time to collision (TTC) and calculates the peripheral vehicle load, based on number of peripheral vehicles in each of the divided plurality of dangerous sections and whether the peripheral vehicles change lanes.

4. The system of claim 2, wherein the dangerous index manager generates the dangerous driving index corresponding to a value which is obtained by considering the trajectory load and the peripheral vehicle load.

5. The system of claim 1, further comprising a road load calculator configured to calculate a road load, based on the at least one of a road shape, a road surface status, and a traffic status which are included in the ambient environment information.
