Method and system for generating a target alert
First Claim
Patent Images
1. A method of generating an alert associated with a radar system, comprising:
- detecting an object when the object is within a predetermined detection zone to provide one or more detection range values indicative of ranges between the radar system and the detected object;
receiving a host vehicle velocity value indicative of a velocity of a host vehicle upon which the radar system is mountedcalculating a relative velocity value indicative of a relative velocity between the host vehicle and the detected object;
combining the one or more detection range values, the relative velocity value, and the host vehicle velocity value to generate the alert, wherein the alert is not generated if the host vehicle velocity and the relative velocity are indicative of the detected object being stationary irrespective of whether the detected object is or is not normally stationary at its location;
identifying if the relative velocity value is greater than an opposite of the host vehicle velocity value plus a fixed single predetermined offset relative velocity value, wherein the fixed single predetermined offset relative velocity value is the same value regardless of the relative velocity value and regardless of the host vehicle velocity value; and
generating the alert only if the relative velocity value is greater than the opposite of the host relative velocity value plus the fixed single predetermined offset relative velocity value.

Abstract
A method of generating a target alert includes combining one or more object detection range values, an object relative velocity value, and a host vehicle velocity value to identify an alert. A system for generating a target alert includes a detection processor to provide one or more detection range values, a transceiver to receive a host vehicle velocity value, a relative velocity calculation processor to calculate a relative velocity value and an alert identification processor to combine the one or more detection range values, the relative velocity value, and the host vehicle velocity value to identify the alert.
