Estimating the term…
A target object position sensing apparatus for a host vehicle, comprises a lane detection apparatus provided on the host vehicle which includes an image acquisition means adapted to capture an image of at least a part of the road ahead of the host vehicle, a vehicle path estimation means adapted to estimate a projected path for the host vehicle, and a target vehicle detection apparatus which is adapted to identify the position of any target objects located on the road ahead of the host vehicle, the position including data representing the distance of the target vehicle from the host vehicle. A first data processing means determines a target lane in which the host vehicle will be located when it has travelled along the projected path by the distance to the target object and a second processing means compares the position of the target vehicle determined by the target vehicle detection means with the position of the target lane to provide a processed estimate of the actual position of the target object.
A target object position sensing apparatus for a host vehicle, the apparatus comprising:
The apparatus of any preceding claim in which the or each captured image is passed to an image processing unit.
The apparatus of any previous claim in which the vehicle path estimation means may estimate the path by projecting a path based upon the heading of the host vehicle.
The apparatus of any preceding claim in which the vehicle path estimation means includes a yaw sensor which is adapted to determine the rate of yaw of the host vehicle in order to provide a measure of the radius of curvature of the path a vehicle is following.
The apparatus of any preceding claim in which the target vehicle detection apparatus comprises an emitter which emits a signal outward in front of the host vehicle and a receiver which is adapted to receive a portion of the emitted signal reflected from objects in front of the vehicle, and a target processing means which is adapted to determine the distance between the host vehicle and the object.
An adaptive cruise control system for a host vehicle comprising:
