Abstract
A lane marker recognition apparatus which recognizes a lane marker based on a captured image of a road surface in the direction in which a vehicle is traveling includes a lane identifying portion that identifies the type of lane that the vehicle is traveling in based on the image, and a timing changing portion which outputs a change command to change the start timing of an operation of an assist system provided in the vehicle to the assist system when the type of lane identified by the lane identifying portion is a predetermined type of lane.
Claims18
A lane marker recognition apparatus which recognizes a lane marker based on a captured image of a road surface in the direction in which a vehicle is traveling, comprising:
- a lane identifying portion that identifies the type of lane that the vehicle is traveling in based on the image;
- and
- a timing changing portion which outputs a change command to change the start timing of an operation of an assist system provided in the vehicle to the assist system when the type of lane identified by the lane identifying portion is a predetermined type of lane.
A preventive safety device comprising:
- a command receiving portion which recognizes a lane marker based on an image that captures the road surface in the direction in which a vehicle is traveling, identifies the type of lane that the vehicle is traveling in based on the image, and receives a change command to change a start timing of an operation when the type of lane identified is a predetermined type of lane;
- a detecting portion that detects an object;
- a calculating portion that calculates the time to collision between the vehicle and the object based on the relative distance and relative speed between the vehicle and the object detected by the detecting portion;
- an operating portion that starts an operation to increase safety when the time calculated by the calculating portion is equal to or less than a predetermined threshold value;
- and
- a resetting portion that resets the threshold value to a larger value when the command receiving portion receives the change command.
A lane departure warning device comprising:
- a command receiving portion which recognizes a lane marker based on an image that captures a road surface in the direction in which a vehicle is traveling, identifies the type of lane that the vehicle is traveling in based on the image, and receives a change command to change a start timing of an operation which is generated when the type of lane identified is a predetermined type of lane;
- an information obtaining portion which obtains road information indicative of the lane width of the lane that the vehicle is traveling in, which is detected based on the image, and the offset from the center of the lane to the center in the width direction of the vehicle, which is detected based on the image;
- a first calculating portion that calculates the width from the center of the lane that the vehicle is traveling in to one of a left or right lane marker based on the lane width indicated by the road information;
- a second calculating portion that calculates the difference of the width calculated by the first calculating portion minus a predetermined threshold value;
- a third calculating portion that calculates the sum of the offset indicated by the road information and the width from the center in the width direction of the vehicle to one of the left or right side of the vehicle;
- an operating portion that starts an operation to issue an alarm to a driver of the vehicle when the sum calculated by the third calculating portion becomes equal to or greater than the difference calculated by the second calculating portion;
- and
- a resetting portion that resets the threshold value to a larger value when the command receiving portion receives the change command.
A lane marker recognition method executed by a lane marker recognition apparatus which recognizes a lane marker based on a captured image of a road surface in the direction in which a vehicle is traveling, comprising:
- identifying the type of lane that the vehicle is traveling in based on the image;
- and
- outputting a change command to change the start timing of an operation of an assist system provided in the vehicle based on the type of lane identified.
