Patent Images
1. An intersection collision prevention system comprising:
- a collision determination unit configured to calculate a first space between a preceding vehicle running in the same direction as a host vehicle and at least one of a yellow center line and an oncoming vehicle located in the opposite lane with respect to the host vehicle and compare the first space to a predetermined second space to determine a danger of a collision; and
a control unit configured to adjust a collision danger warning time point according to a determination result of the collision determination unit,wherein when the collision determination unit determines that there is a danger of a collision, the control unit controls a braking control device so that a deceleration rate is greater than an average deceleration rate.

8. An intersection collision prevention system comprising:
-
a collision determination unit configured to calculate a first space between a preceding vehicle running in the same direction as a host vehicle and at least one of a yellow center line and an oncoming vehicle located in the opposite lane with respect to the host vehicle and compare the first space to a predetermined second space to determine a danger of a collision; and a control unit configured to adjust a collision danger warning time point according to a determination result of the collision determination unit, wherein the collision determination unit determines the danger of a collision by using a width of the host vehicle, a center position in the host vehicle, a width of the oncoming vehicle, a center position in the oncoming vehicle, a width of the preceding vehicle, and a center position in the preceding vehicle.

9. An intersection collision prevention method comprising:
-
calculating a first space between a preceding vehicle running in the same direction as a host vehicle and at least one of a yellow center line and an oncoming vehicle located in the opposite lane with respect to the host vehicle; comparing the first space to a predetermined second space to determine a danger of a collision; and adjusting a collision danger warning time point according to a collision danger determination result, wherein the calculation of a first space comprises calculating the first space by using a width of the host vehicle, a center position in the host vehicle, a width of the oncoming vehicle, a center position in the oncoming vehicle, a width of the preceding vehicle, and a center position in the preceding vehicle. - View Dependent Claims (10, 11, 12, 13, 14)

15. An intersection collision prevention method comprising:
-
calculating a first space between a preceding vehicle running in the same direction as a host vehicle and at least one of a yellow center line and an oncoming vehicle located in the opposite lane with respect to the host vehicle; comparing the first space to a predetermined second space to determine a danger of a collision; adjusting a collision danger warning time point according to a collision danger determination result; and before or after the adjustment of a collision danger warning time point, generating a braking force so that a deceleration rate is greater than an average deceleration rate when the collision danger determination result is that there is a danger of a collision. - View Dependent Claims (16)
