Sensing strategy for damage mitigation in compatability situations
First Claim
1. A crash assessment and safety device activation system, including a host object, comprising:
- a first remote sensor coupled to the host object and adapted to detect a first target object within a region sensed by said first remote sensor and generate a first object signal from said first target object;
a first visual sensor adapted to sense at least a portion of said region sensed by said first remote sensor and therefrom generate a visual signal;
a first safety device actuator, coupled to the host object and adapted to activate a first safety device; and
a controller, coupled to the host object and adapted to receive said first object signal and said visual signal, said controller further adapted to generate a confirmation signal for said first target object through checking said first object signal with said visual signal, said controller further adapted to control said first safety device actuator in response to said confirmation signal.

Abstract
A crash assessment and safety device activation system includes a target object potentially colliding with a host object in motion, is disclosed. A remote sensor is coupled to the host object and adapted to detect a target object within a region sensed thereby and generate an object signal from the target object. A visual sensor is adapted to sense the region sensed by the remote sensor and therefrom generate a visual signal. A safety device actuator is coupled to the host object and adapted to activate a safety device. A controller is attached to the host object, the remote sensor, the visual sensor and the safety device actuator. The control is adapted to assess collision threat from the remote sensor signal and confirm the presence of the target object with the vision sensor. The controller is further adapted to control the safety device actuator in response said threat assessment.

9. A crash threat assessment and damage mitigation method for a host vehicle including a first remote sensor coupled thereto and a visual sensor coupled thereto, comprising:
-
sensing a first target object with the first remote sensor;
generating a first object signal from said first remote sensor;
visually confirming said first target object with the visual sensor; and
deploying a safety device in response to a determination that said first target object is a vehicle and that the host vehicle will crash into said first target object such that a damage resultant from said crash to either said host vehicle or said target object will be reduced by deployment of said safety device. - View Dependent Claims (10, 11, 12, 13)

14. A crash threat assessment and damage mitigation method for a host vehicle including a first remote sensor coupled thereto, a second remote sensor coupled thereto, and a visual sensor coupled thereto, comprising:
-
sensing a first target object with the first remote sensor;
generating a first object signal from the first remote sensor;
verifying said first object signal by polling said first object signal and a signal from the second remote sensor;
visually confirming said first target object with the visual sensor;
determining whether a potential for crash is within a safety device activation threshold; and
deploying an external airbag in response to a determination that said first target object is a vehicle and that the host vehicle will crash into said first target object such that a damage resultant from said crash will be reduced by deployment of said external airbag. - View Dependent Claims (15, 16, 17)
