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 (31)

1. An apparatus for controlling a vehicle, the apparatus comprising:

a first trajectory generator configured to generate a trajectory of a first vehicle based on first vehicle driving information input from a first sensor, the first sensor being configured to sense a driving situation of the first vehicle;

a second trajectory generator configured to generate a trajectory of a second vehicle of peripheral vehicles based on ambient environment information input from a second sensor configured to sense the driving situation of the first vehicle;

a trajectory load calculator configured to calculate a trajectory load based on a comparison of a trajectory distance with a first value, wherein the trajectory distance is a difference between the trajectory of the second vehicle and the trajectory of the first vehicle;

a dangerous index manager configured to generate the dangerous driving index, the dangerous driving index corresponding to the calculated trajectory load; and

a vehicle controller configured to receive the dangerous driving index from the trajectory load calculator, and to control at least one of an engine operation, a braking operation, or a steering operation, in response to the dangerous driving index being higher than a second value.

2. The apparatus of claim 1 , further comprising a peripheral vehicle load calculator configured to calculate a peripheral vehicle load based on a number of the peripheral vehicles and lane changing information of the peripheral vehicles.

3. The apparatus of claim 2 , wherein the peripheral vehicle load calculator is further configured to divide dangerous sections with respect to the first vehicle based on a time to collision (TTC), and to calculates the peripheral vehicle load based on a number of peripheral vehicles in each of the divided plurality of dangerous sections and the lane changing information.

4. The apparatus of claim 2 , wherein the dangerous driving index corresponds to a value obtained by considering the trajectory load and the peripheral vehicle load.

5. The apparatus 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, or a traffic status.

6. The apparatus of claim 5 , wherein the dangerous driving index is based on the trajectory load and the road load.

7. The apparatus of claim 1 , further comprising:

a peripheral vehicle load calculator configured to calculate a peripheral vehicle load based on a number of the peripheral vehicles and lane changing information of the peripheral vehicles; and

a road load calculator configured to calculate a road load based on the at least one of a road shape, a road surface status, or a traffic status,

wherein the dangerous driving index is based on the peripheral vehicle load and the road load.

8. A method for controlling a vehicle, the method comprising:

generating a trajectory of a first vehicle based on driving information of a first vehicle input from a first sensor, the first sensor being configured to sense a driving situation of the first vehicle;

generating a trajectory of a second vehicle of peripheral vehicles based on ambient environment information input from a second sensor configured to sense the driving situation of the first vehicle;

calculating a trajectory load based on a comparison result of a trajectory distance and a first value, wherein the trajectory distance is a difference between the trajectory of the second vehicle and the trajectory of the first vehicle;

generating a dangerous driving index corresponding to the calculated trajectory load; and

controlling at least one of an engine operation, a braking operation, or a steering operation, in response to the dangerous driving index being higher than a second value.

9. The method of claim 8 , further comprising calculating a peripheral vehicle load, based on a number of peripheral vehicles and lane changing information of the peripheral vehicles.

10. The method of claim 9 , wherein the calculating of the peripheral vehicle load peripheral comprises:

dividing a plurality of dangerous sections with respect to the first vehicle, based on a time to collision (TTC); and

calculating the peripheral vehicle load, based on a number of peripheral vehicles in each of the divided plurality of dangerous sections and the lane changing information.

11. The method of claim 8 , further comprising calculating a road load based on the at least one of a road shape, a road surface status, or a traffic status.

12. The method of claim 11 , wherein the dangerous driving index is based on the trajectory load and the road load.

13. The apparatus of claim 1 , wherein the ambient environment information is generated by a detection section generator configured to detect an optimized section and to recognize an ambient environment in the optimized detection section.

14. The apparatus of claim 13 , wherein the section generator further comprises a target tracer configured to distinguish an obstacle based on a detection signal of the obstacle and to generate a track comprising a covariance of an error of the obstacle and a position estimation value of the obstacle.

15. The apparatus of claim 13 , wherein the optimized section is based on a probability value at or below a threshold in a Gaussian probability distribution having a residual covariance as a variance, wherein the probability value is a gate probability optimized by a time based Kalman filter.

16. The apparatus of claim 8 , wherein the controlling of the at least one of the engine operation, the braking operation, or the steering operation restricts a driving function of the first vehicle.
