Claim of US Patent No. 9,342,986

1. A computer based method comprising:
receiving a plurality of vehicle environment inputs, the inputs comprising a current position for each of a plurality of objects
located around a vehicle;

determining, based on the inputs, a possible outcome involving the plurality of objects, the possible outcome comprising a
predicted position for each of the involved objects;

determining a numerical likelihood of occurrence of the possible outcome based on the inputs;
determining, for each of the involved objects, a current risk value for the object based on the current position of the object,
and a predicted risk value for the object based on the predicted position of the object;

determining, for each of the involved objects, a total risk value based on the current risk value and based on the predicted
risk value weighted by the numerical likelihood of occurrence; and

controlling a driver assistance system of the vehicle based on the total risk values of the involved objects;
wherein determining the numerical likelihood of occurrence of the possible outcome comprises:
determining a plurality of memberships by the inputs in a plurality of input membership functions;
combining the memberships into a plurality of permutations of the input membership functions;
mapping the permutations to a plurality of outcome membership functions;
aggregating the outcome membership functions;determining the numerical likelihood of occurrence based on the aggregation.
