Method and apparatus for activating a crash countermeasure
First Claim
1. A method for operating a pre-crash sensing system for a first vehicle proximate a second vehicle a counter-measure system comprising:
- generating an object detection signal over a field of view from a first vehicle;
receiving the object detection signal at the second vehicle when positioned within the field of view;
generating a response signal in response to said high frequency signal, said response signal including a key;
establishing an communication link between said first vehicle and said second vehicle using said key;
communicating a first vehicle data signal to the second vehicle using said key; and
communicating a second vehicle data signal to the second vehicle using said key.

Abstract
A system is provided (10) for sensing a potential collision of a first vehicle (11) with a second vehicle (72) that transmits a second vehicle information signal. The pre-crash sensing system (10) includes a threat registry (17), a position sensor (18) generating a first position signal corresponding to a position of the first vehicle, and a first sensor (20) generating sensor signals from the first vehicle. The vehicle also includes a receiver (22) that receives the second vehicle position signal from the second vehicle and a countermeasure system (40). A controller (12), (13) is coupled to the threat registry, the position sensor, the first sensor, the receiver, and the countermeasure system. The controller determines a time to collision and a distance to collision in response to the second vehicle information, the first position signal and the second vehicle position. The controller determines a threat level as a function of the time to collision and the distance to collision, activating the countermeasure system in response to the threat level and storing the vehicle threat level in the threat registry.
