A system, method and product for determining a vehicle key fob location. The system may include a control unit for mounting in a vehicle and configured to receive multiple signals, each representing a strength of a wireless signal transmitted between the fob and one of multiple antennas located on a vehicle, and multiple neural networks having a cascade topology. The neural networks may include a first neural network for determining one of a vehicle internal position and a vehicle external position of the fob based on the wireless signal strengths, a second neural network in communication with the first neural network for determining one of multiple vehicle interior positions of the fob based on the wireless signal strengths, and a third neural network in communication with the first neural network for determining one of multiple vehicle exterior positions of the fob based on the wireless signal strengths. |

1. A system for determining a location of a key fob for use in a vehicle access system, the location system comprising:
a control unit for mounting in a vehicle, the control unit configured to receive a plurality of signals, each signal representing a strength of a wireless signal transmitted between the key fob and one of a plurality of antennas located on a vehicle; and a plurality of neural networks having a cascade topology, the plurality of neural networks comprising
a first neural network for determining one of a vehicle internal position and a vehicle external position of the key fob based on the wireless signal strengths, wherein determining one of a vehicle internal position and a vehicle external position comprises calculating a plurality of intermediate internal/external position neurons having learned weights and activation functions associated therewith, and calculating an internal/external output neuron for use in indicating one of the vehicle internal position and the vehicle external position of the key fob,a second neural network in communication with the first neural network, the second neural network for determining one of a plurality of vehicle interior positions of the key fob based on the wireless signal strengths, wherein determining one of a plurality of vehicle interior positions comprises calculating a plurality of intermediate interior position neurons having learned weights and activation functions associated therewith, and calculating a plurality of interior position output neurons for use in indicating one of a plurality of vehicle interior positions of the key fob, anda third neural network in communication with the first neural network, the third neural network for determining one of a plurality of vehicle exterior positions of the key fob based on the wireless signal strengths, wherein determining one of a plurality of vehicle exterior positions of the key fob comprises calculating a plurality of intermediate exterior position neurons having learned weights and activation functions associated therewith, and calculating a plurality of exterior position output neurons for use in indicating one of a plurality of vehicle exterior positions of the key fob. |
