Collision reducing device
First Claim
1. A collision reducing device comprising:
- a sensor that is configured to detect information about objects around an own vehicle;
a detector that is configured to detect an object existing in the information;
a first actuating unit that is configured to determine whether a number of a collision possibility between the object and the own vehicle exceeds a first reference value by more than a first number of times in a first number of frames;
a second actuating unit that is configured to determine whether a number of the collision possibility exceeds the first reference value by more than a second number of times in a second number of frames, the second number being greater than the first number;
a selecting unit that is configured to select one of the first actuating unit and the second actuating unit in accordance with the collision possibility and a second reference value of a time to collision; and
a controller that is configured to control the own vehicle to reduce collision influence based on selected actuating.

Abstract
A collision reducing device including a radar, an image sensor, a collision mitigation, and a brake. A collision predicting section of the collision mitigation has a first actuating section for causing a vehicle control section to perform running control when a collision possibility exceeds a reference value in one-frame determination, a second actuating section for causing the vehicle control section to perform running control when the collision possibility exceeds a reference value in M-frame determination, and a selecting section for selectively operating the first actuating section and second actuating section, so that the vehicle control section can be operated by two kinds of numbers of determinations, whereby the speed of collision determination can be secured by a smaller number of determinations when operating the first actuating section, while malfunctions can be reduced more by a greater number of determinations when operating the second actuating section.

8. A collision reducing device comprising:
-
a sensor that detects an object existing about an own vehicle; and an ECU that is configured to; determine whether a number of a collision possibility between the object and the own vehicle exceeds a first reference value by more than a first number of times or more in a first number of frames, determine whether or not to reduce collision influence in accordance with the collision possibility determination based on a second reference value that is a second number of times or more in a second number of frames, the second number being greater than the first number, select one of a first actuating unit and a second actuating unit in accordance with a time to collision, and configured to reduce the collision influence based on selected actuating.

9. A collision reducing method comprising:
-
detecting information about an own vehicle; detecting an object existing in the information; controlling, by a first actuating unit, the own vehicle to reduce collision influence in accordance with whether a number of a collision possibility between the object and the own vehicle exceeds a first reference value by more than a first number of times in a first number of frames; controlling, by a second actuating unit, the own vehicle to reduce collision influence in accordance with whether a number of the collision possibility exceeds the first reference value by more than a second number of times in a second number of frames, the second number being greater than the first number; selecting one of the first actuating unit and the second actuating unit in accordance with the collision possibility and a second reference value of a time to collision; and controlling the own vehicle to reduce collision influence based on selected actuating.
