DRIVER ASSISTANCE SYSTEMS USING RADAR AND VIDEO
First Claim
1. A driver assistance system comprising:
- a RADAR system;
a video system; and
a vehicle control system, the vehicle control system including a processor configured toidentify an object as a target vehicle when the RADAR system or both the RADAR system and the video system detect the object in a driving lane occupied by a host vehicle,track position and speed of the target vehicle, andoperate the host vehicle based at least in part on the position and speed of the target vehicle.

Abstract
A driver assistance system that includes a RADAR system, a video system, a brake control unit, and a controller, such as an engine control unit. The RADAR system is mounted on the front of the vehicle and is positioned to detect the location of various objects. The video system captures video images. The controller receives data from both the RADAR system and the video system and identifies objects and their locations based on both the RADAR and the video data. The controller then adjusts the operation of the engine and the vehicle brakes based on the identified objects and their locations. In some embodiments, the driver assistance system also includes a human-machine interface that notifies the driver when an object is identified and located.

13. A driver assistance system comprising:
-
a RADAR system; a video system; and a vehicle control system, the vehicle control system including a processor configured to receive an indication from the RADAR system of a new object detected in a driving lane occupied by a host vehicle, determine if another vehicle has previously been identified as a target vehicle and is currently being monitored by the vehicle control system in an adjacent driving lane, identify the new object as a target vehicle when there is no other vehicle currently being monitored by the vehicle control system in the adjacent lane, determine, by the RADAR system, a relative velocity of the new object, identify the new object as a target vehicle when the relative velocity of the new object is greater than a threshold, and identify the new object as a non-vehicle when another vehicle is currently being monitored by the vehicle control system in an adjacent lane, the relative velocity of the new object is below the threshold, and the video system detects a free lane ahead of the host vehicle. - View Dependent Claims (14)
