SYSTEM AND METHOD FOR VEHICLE SENSOR FUSION
First Claim
Patent Images
1. A method for tracking targets sensed by sensors in a host motor vehicle, the method comprising the steps of:
- determining if a first target is part of an existing fused track in a plurality of fused tracks, where each of the plurality of fused tracks includes one or more sensed targets;
adding the first target to an existing fused track if the first target is determine to be part of an existing fused track of targets; and
creating a new fused track and adding the first target to the new fused track if the first target is determined to not be part of an existing fused track of targets.

Abstract
A system and method is provided for tracking and evaluating targets sensed by one or more active safety sensors in a motor vehicle. The system and method tracks detected targets from one or more sensors as fused tracks, and determines the maturity and plausibility of such fused tracks in determining an appropriate response. This facilitates the reliable detection and evaluation of targets based on sensor data from different sensors.

11. A system for tracking targets in a host motor vehicle comprising:
-
a first sensor configured to sense targets proximate to the host motor vehicle, the first sensor having a first range; a second sensor configured to sense targets proximate to the host motor vehicle, the second sensor having a second range; a processor coupled to the first sensor and the second sensor, the processor configured to; determine if a first target is part of an existing fused track in a plurality of fused tracks, where each of the plurality of fused tracks includes one or more sensed targets being tracked by the processor; add the first target to an existing fused track if the first target is determine to be part of an existing fused track; and create a new fused track and add the first target to the new fused track if the first target is determined to not be part of an existing fused track. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
