COLLISION AVOIDANCE SYSTEM AND METHOD
First Claim
Patent Images
1. A method of assisting avoidance of a collision between a vehicle and an object, the vehicle being a land vehicle, the object and the vehicle being located within an environment, the method comprising:
- receiving an acoustic signal from the object using microphones supported by the vehicle;
creating an acoustic model of the environment using topological data relating to the environment; and
determining a position of the object using the acoustic signal and the acoustic model of the environment,the environment including a structure that blocks a direct view of the object from the vehicle.

11. A method of assisting collision avoidance between a vehicle and an object within an environment, the vehicle being a land vehicle, the method comprising:
-
receiving an acoustic signal from the object using microphones supported by the vehicle; creating an acoustic model of the environment; locating the object using matched field processing of the acoustic signal, using the acoustic model of the environment; and providing an alert so as to assist avoidance of a collision between the vehicle and the object, the object being hidden from view from the vehicle. - View Dependent Claims (12, 13, 14, 15, 16)

17. An apparatus operable to assist avoidance of a collision between a vehicle and an object within an environment, the object producing an acoustic signal, the apparatus comprising:
-
microphones supported by the vehicle and operable to receive acoustic signal; a processor, receiving microphone signals from the microphones, and operable to use an acoustic model of the environment to determine the location of the object within the environment; and an alert device, operable to provide an alert indicative of the location of the object, the vehicle being a land vehicle, the microphones being located behind a trim component of the vehicle. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
