1. A pre-crash sensing system coupled to a countermeasure system having at least a first countermeasure and a second countermeasure comprising:
- a vision system generating an object size signal and an object distance signal; and
a controller coupled to said vision system for deploying either said first countermeasure or said first and second countermeasures in response to said object distance signal and said object size signal.

Abstract
A pre-crash sensing system is coupled to a countermeasure system that has at least a first countermeasure and a second countermeasure. The pre-crash sensing system has a vision system (26) that generates an object size signal and an object distance signal. A controller (12) is coupled to the vision system (26) and deploys either the first countermeasure or first and second countermeasures in response to the object distance and object size.

7. A method for operating a pre-crash sensing system for an automotive vehicle having a countermeasure system, said method comprising:
-
establishing a decision zone relative to the vehicle; detecting an object within the decision zone using a vision system; determining an object distance and relative velocity using a vision system; determining an object size; and activating the countermeasure system in response to the object size and relative velocity. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
