Abstract

A vehicle driving control apparatus includes an object detection unit configured to detect an object located outside a vehicle; and at least one processor configured to provide a first control signal and a second control signal based on information regarding the object detected by the object detection unit. The at least one processor provides the first control signal and the second control signal by: based on the information regarding the object, providing the first control signal to cause one of an increase or a decrease in a speed of the vehicle during a first time period; and based on the information regarding the object and based on the first control signal provided during the first time period, providing the second control signal to cause the other of the increase or the decrease in the speed of the vehicle during a second time period.

First claim

What is claimed is:

1 . A vehicle driving control apparatus comprising:
an object detection unit configured to detect an object located outside a vehicle; and at least one processor configured to provide a first control signal and a second control signal based on information regarding the object detected by the object detection unit, wherein the at least one processor provides the first control signal and the second control signal by:
based on the information regarding the object, providing the first control signal to cause one of an increase or a decrease in a speed of the vehicle during a first time period; and
based on the information regarding the object and based on the first control signal provided during the first time period, providing the second control signal to cause the other of the increase or the decrease in the speed of the vehicle during a second time period.

2 . The vehicle driving control apparatus according to claim 1 , wherein the at least one processor is further configured to determine both the first control signal and the second control signal prior to providing either the first control signal or the second control signal.

3 . The vehicle driving control apparatus according to claim 1 , wherein the at least one processor is further configured to determine both the first time period and the second time period prior to providing either the first control signal or the second control signal.

4 . The vehicle driving control apparatus according to claim 1 , wherein the at least one processor is further configured to determine at least one of the first time period or the second time period by:
determining at least one location that corresponds to a start time of the at least one of the first time period or the second time period.

5 . The vehicle driving control apparatus according to claim 1 , wherein the at least one processor is further configured to provide the first control signal and the second control signal based on the vehicle being in a state of following a preceding vehicle.

6 . The vehicle driving control apparatus according to claim 1 , wherein the at least one processor is further configured to:
acquire information regarding a roadway on which the vehicle is travelling; and provide the first control signal and the second control signal based on the information regarding the roadway on which the vehicle is travelling.

7 . The vehicle driving control apparatus according to claim 6 , wherein the at least one processor is further configured to:
acquire information regarding an intersection ahead of the vehicle; before the vehicle enters the intersection, provide the first control signal during the first time period to reduce a speed of the vehicle; and after the vehicle exits the intersection, provide the second control signal to increase the speed of the vehicle.

8 . The vehicle driving control apparatus according to claim 7 , wherein the at least one processor is further configured to:
acquire information regarding a traffic light and information regarding a pedestrian in an area around the intersection; and provide the first control signal and the second control signal based on a determination that the pedestrian is present on the roadway on which the vehicle is travelling in a state in which the traffic light is green.

9 . The method according to claim 6 , wherein the at least one processor is further configured to:
acquire information regarding a curve ahead of the vehicle; before the vehicle enters the curve, provide the first control signal during the first time period to reduce a speed of the vehicle; and after the vehicle exits the curve, provide the second control signal during the second time period to increase a speed of the vehicle.

10 . The vehicle driving control apparatus according to claim 9 , wherein the at least one processor is further configured to:
acquire information regarding a lane of the curve in which the vehicle is expected to travel; and based on the vehicle entering the curve, provide a steering control signal that controls the vehicle to travel closer to a lane-marker of the lane that is formed on a side of the lane that is farther from a curvature direction of the curve.

11 . The vehicle driving control apparatus according to claim 9 , wherein the at least one processor is further configured to:
acquire information regarding a lane of the curve in which the vehicle is expected to travel; and based on the vehicle travelling in the middle of the curve, provide a steering control signal that controls the vehicle to travel closer to a lane-marker of the lane that is formed on a side of the lane that is closer to a curvature direction of the curve.

12 . The vehicle driving control apparatus according to claim 9 , wherein the at least one processor is further configured to:
Based on the vehicle entering the curve, provide a steering control signal that controls the vehicle to move to a lane that is closer to a curvature direction of the curve.

13 . The vehicle driving control apparatus according to claim 9 , wherein the at least one processor is further configured to:
based on the vehicle exiting the curve, provide a steering control signal that controls the vehicle to move to a lane that is farther from a curvature direction of the curve.

14 . The vehicle driving control apparatus according to claim 9 , wherein the at least one processor is further configured to:
acquire curvature information of the curve; and determine a start point of the first time period based on the curvature information.

15 . The vehicle driving control apparatus according to claim 14 , wherein the at least one processor is further configured to determine a degree of speed reduction for the vehicle based on the curvature information.

16 . The vehicle driving control apparatus according to claim 6 , wherein the at least one processor is further configured to:
acquire information regarding a construction zone ahead of the vehicle; before the vehicle enters the construction zone, provide the first control signal during the first time period to reduce a speed of the vehicle; and after the vehicle exits the construction zone, provide the second control signal during the second time period to increase the speed of the vehicle.

17 . The vehicle driving control apparatus according to claim 6 , wherein the at least one processor is further configured to:
acquire information regarding a crosswalk ahead of the vehicle; before the vehicle enters the crosswalk, provide the first control signal during the first time period to reduce a speed of the vehicle, and after the vehicle exits the crosswalk, provide the second control signal during the second time period to increase the speed of the vehicle.

18 . The vehicle driving control apparatus according to claim 17 , wherein the at least one processor is further configured to:
acquire information regarding a traffic light and information regarding a pedestrian in an area around the crosswalk; and provide the first control signal and the second control signal based on a determination that the pedestrian is present in the crosswalk in a state in which the traffic light is green.

19 . The vehicle driving control apparatus according to claim 6 , wherein the at least one processor is further configured to:
acquire traffic sign information that indicates at least one of speed limit information, tunnel information, accident prone area information, foggy area information, school zone information, or
