Abstract

An object of the invention is to provide a safety driving support apparatus capable of detecting a dangerous moving object with high accuracy at quick timing. A safety driving support apparatus 100 of the invention includes a traffic obstacle detection section 101 for detecting a traffic obstacle of the periphery of a vehicle, a speed change induced event detection section 106 for detecting an event of inducing a sudden change in behavior of a pedestrian from a traffic obstacle detected by the traffic obstacle detection section 101, a speed change detection section 102 for detecting a sudden change in behavior of a pedestrian from a traffic obstacle detected by the traffic obstacle detection section 101, and a dangerous pedestrian detection section 109 for deciding that the pedestrian is a dangerous pedestrian when the speed change detection section 102 detects a change in behavior of a pedestrian within a certain time from a point in time when a speed change induced event of a pedestrian detected by the speed change induced event detection section 106 occurs.

Claims

1. A safety driving support apparatus, comprising:

a traffic obstacle detection section that detects a moving object including a vehicle or a pedestrian present in a periphery of one'"'"'s vehicle, the moving object and a traffic regulation substance, or the moving object and a road shape;

a speed change induced event detection section that detects a speed change induced event which is defined as an event of inducing a change in speed of the moving object on the basis of a detection result of the traffic obstacle detection section;

a speed change detection section that detects the change in speed of the moving object on the basis of the detection result of the traffic obstacle detection section; and

a dangerous moving object detection section that determines the moving object as a dangerous moving object when the speed change induced event detection section detects occurrence of the speed change induced event at present or in the past and the speed change detection section detects the change in speed of the moving object,

wherein the traffic obstacle detection section detects a position or a shape feature of the traffic regulation substance, a position or a shape feature of the road shape, or a movement state, a position or a shape feature of the moving object present in the periphery of one'"'"'s vehicle,

the safety driving support apparatus further comprising a speed change induced event selection section that selects the speed change induced event to be detected by the speed change induced event detection section on the basis of information detected by the traffic obstacle detection section.

3. The safety driving support apparatus according to claim 1, further comprising:

a one'"'"'s vehicle movement path prediction section that predicts a path of one'"'"'s vehicle,

wherein the speed change induced event selection section selects the speed change induced event to be detected within a range determined on the basis of a path of one'"'"'s vehicle predicted by the one'"'"'s vehicle movement path prediction section.

5. The safety driving support apparatus according to claim 1, wherein the speed change induced event detection section detects occurrence of the speed change induced event within a range determined in correspondence with the speed change induced event selected by the speed change induced event selection section.

6. The safety driving support apparatus according to claim 1, wherein the speed change detection section sets a moving object present within a range determined in correspondence with the speed change induced event selected by the speed change induced event selection section as a detection object.

7. The safety driving support apparatus according to claim 1, further comprising:

a sight line detection section that detects a sight line direction of a driver;

a visual recognition determination section that determines whether the driver visually recognizes the moving object on the basis of the sight line direction detected by the sight line detection section and a presence position of the moving object detected by the traffic obstacle detection section;

a storage section that stores information indicating the speed change induced event in relation to information about the traffic regulation substance, the road shape or the moving object,

wherein the dangerous moving object detection section determines the moving object as a dangerous moving object when the speed change detection section detects the change in speed of the moving object which is determined that the moving object is visually recognized within the past predetermined time by the visual recognition determination section; and

wherein the speed change induced event selection section selects the speed change induced event to be detected by the speed change induced event detection section form the information stored in the storage section.

9. The safety driving support apparatus according to claim 1, further comprising:

an acquisition section that acquires information indicating the speed change induced event from a roadside system installed in a road through a road-to-vehicle communication section,

wherein the speed change induced event selection section selects the speed change induced event to be detected by the speed change induced event detection section from the information acquired by the acquisition section.

10. The safety driving support apparatus according to claim 1, further comprising:

a information providing section that provides information about avoidance of contact with the dangerous moving object to a driver when the dangerous moving object is detected by the dangerous moving object detection section.

11. The safety driving support apparatus according to claim 1, further comprising:

a vehicle control section that controls a vehicle for avoidance of contact with the dangerous moving object when the dangerous moving object is detected by the dangerous moving object detection section.

2. (canceled)

4. The safety driving support apparatus according to claim 2, further comprising:

a one'"'"'s vehicle travel information detection section that detects travel information about one'"'"'s vehicle,

wherein the one'"'"'s vehicle movement path prediction section predicts the path of one'"'"'s vehicle form the travel information about one'"'"'s vehicle detected by the one'"'"'s vehicle travel information detection section.

8. (canceled)
