Abstract

An apparatus and a method for controlling a stop of a vehicle may include an information collection system collecting at least one of road information, position information, and driving information; and a control system stopping the vehicle on a basis of the information collected by the information collection system in a case of emergency while the vehicle is running on a road.

Claims

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

an information collection system collecting at least one information of road information, position information, and driving information; and

a control system stopping the vehicle at a predetermined deceleration rate on a basis of the at least one information collected by the information collection system in a case of emergency while the vehicle is running on a road,

wherein the control system is configured to determine the road on which the vehicle is running as a first curve when a curvature of the road exceeds a first threshold, maintains a current speed of the vehicle until the vehicle is out of the first curve, and stops the vehicle at a predetermined deceleration rate.

2. The apparatus according to claim 1, wherein the control system is configured to determine the road on which the vehicle is running as a second curve when the curvature of the road exceeds a second threshold and is less than or equal to the first threshold, checks a direction of turn of the second curve and a lane on which the vehicle is miming, maintains the current speed of the vehicle until the vehicle is out of the second curve when the second curve is a left-turn curve and the vehicle is running on a first lane or when the second curve is a right-turn curve and the vehicle is running on an outermost lane, and stops the vehicle at the predetermined deceleration rate.

3. The apparatus according to claim 1, wherein the control system is configured to prevent the vehicle from stopping inside of a tunnel and within a distance less than or equal to a threshold from an exit of the tunnel when there is the tunnel in a front of the vehicle.

4. The apparatus according to claim 1, wherein the control system is configured to determine an elevation change rate of a section in which the vehicle is currently running on a basis of information about an elevation, maintains the current speed of the vehicle until the vehicle passes through the section when the determined elevation change rate exceeds a predetermined value, and stops the vehicle at the predetermined deceleration rate.

5. A method for controlling a stop of a vehicle, the method comprising:

collecting, by an information collection system, at least one information of road information, position information, and driving information; and

stopping, by a control system, the vehicle at a predetermined deceleration rate on a basis of the collected at least one information in a case of emergency while the vehicle is running on a road,

wherein the stopping of the vehicle comprises determining the road on which the vehicle is running as a first curve when a curvature of the road exceeds a first threshold, maintaining a current speed of the vehicle until the vehicle is out of the first curve, and stopping the vehicle at a predetermined deceleration rate.

6. The method according to claim 5, wherein the stopping of the vehicle comprises determining the road on which the vehicle is running as a second curve when the curvature of the road exceeds a second threshold and is less than or equal to the first threshold, checking a direction of turn of the second curve and a lane on which the vehicle is running, maintaining the current speed of the vehicle until the vehicle is out of the second curve when the second curve is a left-turn curve and the vehicle is running on a first lane or when the second curve is a right-turn curve and the vehicle is running on an outermost lane, and stopping the vehicle at the predetermined deceleration rate.

7. The method according to claim 5, wherein the stopping of the vehicle comprises preventing the vehicle from stopping inside of a tunnel and within a distance less than or equal to a threshold from an exit of the tunnel when there is the tunnel in a front of the vehicle.

8. The method according to claim 5, wherein the stopping of the vehicle includes determining an elevation change rate of a section in which the vehicle is currently running on a basis of information about an elevation, maintaining the current speed of the vehicle until the vehicle passes through the section when the determined elevation change rate exceeds a predetermined value, and stopping the vehicle at the predetermined deceleration rate.
