METHOD FOR OPERATING A PRE-CRASH SENSING SYSTEM IN A VEHICLE HAVING EXTERNAL AIRBAGS
First Claim
1. A pre-crash sensing and countermeasure deployment control system for an automotive vehicle coupled to a countermeasure system having an external airbag system, said pre-crash sensing system and countermeasure deployment comprising:
- an object classifier generating an object classification signal; and
a controller coupled to said object classifier for varying an activation level of the external airbag in response to said object classification signal.

Abstract
A pre-crash sensing system (10) for an automotive vehicle (50) is coupled to an external airbag system (120). The external airbag system (120) may include a bumper airbag (126), a grill airbag (122) or a bumper airbag and a grill airbag. An object classifier is used to generate an object classification signal. A controller (12) is coupled to the object classifier and the external airbag system for varying an activation level of the external airbag system (120) in response to the object classification signal.

13. A method for operating a pre-crash sensing and countermeasure deployment control system for an automotive vehicle having an external airbag system, said method comprising:
-
establishing a decision zone relative to the vehicle;
detecting an object within the decision zone;
classifying the object into an object classification;
determining an external airbag activation rate corresponding to the object classification; and
activating the external airbag system at the activation rate. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method for operating a pre-crash sensing and countermeasure deployment control system for an automotive vehicle having an external airbag system, said method comprising:
-
detecting an object;
classifying the object;
when the object is a pedestrian, activating an external airbag of the external airbag system at a first rate;
when the object is a second vehicle, activating the external airbag system at a second rate greater than the first rate. - View Dependent Claims (20)
