Abstract
A vehicle includes a first laser module configured to emit a first light beam and project a first dot onto a preceding vehicle, a second laser module configured to emit a second light beam and project a second dot onto the preceding vehicle, a camera configured to generate a digital image of the first and second dots projected onto the preceding vehicle, and a controller configured to determine, from the digital image, a width between the first and second dots, and subsequently determine a following distance between the vehicle and the preceding vehicle based on linear interpolation using the determined width.
Claims16
A vehicle comprising:
- a first laser disposed on a front of the vehicle and oriented to emit a first light beam and project a first dot onto a preceding vehicle;
- a second laser disposed on the front of the vehicle and oriented to emit a second light beam and project a second dot onto the preceding vehicle such that a width is established between the first and second dots;
- a camera configured to generate a digital image of the first and second dots projected onto the preceding vehicle;
- and
- a controller configured to determine, from the digital image, the width between the first and second dots, and subsequently determine a following distance between the vehicle and the preceding vehicle based on linear interpolation using the determined width.
A vehicle comprising:
- a first laser configured to emit a first light beam and project a first dot onto a preceding vehicle;
- a second laser configured to emit a second light beam and project a second dot onto the preceding vehicle;
- a camera configured to generate a digital image of the first and second dots projected onto the preceding vehicle;
- and
- a controller configured to determine, from the digital image, a width between the first and second dots, and subsequently determine a following distance between the vehicle and the preceding vehicle based on linear interpolation using the determined width,
- wherein the width between the first and second dot is determined in pixels,
- wherein determining the following distance based on linear interpolation further includes using a predetermined second pixel width and second distance, and a predetermined third pixel width and third distance.
A method of controlling a vehicle having a driver assist system with first and second lasers disposed on a front of the vehicle and a camera, the method comprising:
- emitting a first beam of light from the first laser to project a first dot onto a preceding vehicle;
- emitting a second beam of light from the second laser to project a second dot onto the preceding vehicle such that a width is established between the first and second dots;
- generating, with the camera, a digital image of the first and second dots projected onto the preceding vehicle;
- determining, with a controller, the width between the first and second dot on the digital image;
- and
- determining, with the controller, a following distance between the vehicle and the preceding vehicle based on linear interpolation using the determined width.
