Abstract
A lane following assist apparatus and a control method thereof are provided. The lane following assist apparatus includes a camera that captures an image in front of a vehicle and a processor that receives a forward image from the camera. The processor obtains line information from the forward image, calculates a vehicle offset based on the line information, variably sets a target look-ahead distance depending on whether the vehicle offset is greater than a threshold, and performs lane following assist control using the target look-ahead distance.
Claims6
A lane following assist apparatus, comprising:
- a camera configured to capture an image in front of a vehicle;
- and
- a processor configured to receive a forward image from the camera,
- wherein the processor is configured to:
- obtain line information from the forward image;
- calculate a straight distance between a target traveling route and a center of a vehicle as a vehicle offset based on the line information, wherein the target traveling route is set along the center of both lines of a lane on which the vehicle should travel;
- calculate a difference between the vehicle offset and a predetermined threshold when the vehicle offset is greater than a predetermined threshold;
- change a previously set preview time based on the calculated difference;
- set a target look-ahead distance based on the changed preview time and a vehicle speed;
- and
- perform lane following assist control using the target look-ahead distance.
A control method of a lane following assist apparatus, the control method comprising:
- obtaining line information from a forward image obtained using a camera;
- calculating a straight distance between a target traveling route and a center of the vehicle as a vehicle offset based on the line information, wherein the target traveling route is set along the center of both lines of a lane on which the vehicle should travel;
- computing a difference between the vehicle offset and a predetermined threshold when the vehicle offset is greater than the predetermined threshold;
- changing a previously set preview time based on the calculated difference;
- setting a target look-ahead distance based on the changed preview time and a vehicle speed;
- and
- performing lane following assist control using the target look-ahead distance.
