Abstract
Abstract A collision warning and safety countermeasure system ( 10 ) for an automotive vehicle ( 12 ) having a vehicle sensor complex ( 18 ) and generating a vehicle sensor complex signal is provided. The system ( 10 ) includes a sensor fusion ( 14 ) that generates an object status signal. A threat assessor ( 16 ) generates a vehicle status signal in response to the vehicle sensor complex signal. The threat assessor ( 16 ) also in response to the vehicle status signal and the object status signal generates a collision assessment signal. An active countermeasure controller ( 20 ) generates an active countermeasure signal in response to the collision assessment signal and the vehicle sensor complex signal. A passive countermeasure controller ( 22 ) generates a passive countermeasure signal in response to the collision assessment signal and the vehicle sensor complex signal. An indicator ( 30 ) generates a collision-warning signal in response to the collision assessment signal. A method for performing the same is also provided.
