Method for determining a danger zone for a pre-crash sensing system in a vehicle having a countermeasure system
First Claim
1. A pre-crash sensing system for a source vehicle having a source vehicle length and a source vehicle width coupled to a countermeasure system comprising:
- an object sensor generating an object distance signal and object relative velocity signal and an object classification signal; and
a controller coupled to said object sensor for activating the countermeasure system in response to said object distance, relative velocity and said object classification signal.

Abstract
A pre-crash sensing system (10) for a source vehicle (50) having a source vehicle length and a source vehicle width that is coupled to a countermeasure system (30) is described. The system includes an object sensor (17) having a radar sensor (18) generating an object distance signal and an object relative velocity signal, and a vision system (20) generating an object classification signal. A controller (12) is coupled to the object sensor for activating the countermeasure system (30) based on the object distance, relative velocity and the object classification signal.
