1. A method comprising:
- receiving a plurality of vehicle environment inputs, the inputs comprising a position in two dimensions for each of a plurality of objects located around a vehicle, each object located in one of four quadrants surrounding the vehicle;
determining an object risk value for each of the objects by applying a set of rules to each of the objects, at least a plurality of the object risk values being non-zero, indicating the objects pose a risk to the vehicle;
aggregating the object risk values in a front quadrant to generate a front quadrant risk value;
aggregating the object risk values in a back quadrant to generate a back quadrant risk value;
aggregating the object risk values in a left quadrant to generate a left quadrant risk value;
aggregating the object risk values in a right quadrant to generate a right quadrant risk value,wherein at least one of the front, back, left, and right quadrant risk values is determined by aggregating at least two of the non-zero object risk values; and
controlling a driver assistance system of the vehicle based on the quadrant risks.

Abstract
A driver assistance system is described that takes as input a number of different types of vehicle environment inputs to provide driver assistance to a driver. To provide the assistance, the driver assistance system synthesizes the inputs. For objects in the vehicle environment detected in the inputs, object risk values are determined by applying a set of rules to the objects. The object risk values are aggregated by quadrant to generate a set of quadrant risk values. A driver assistance system of the vehicle is controlled based on the quadrant risks.

15. A system comprising:
-
a knowledge base comprising a non-transitory computer readable storage medium, the knowledge base storing a set of rules; an electronic control unit (ECU) comprising a processor and configured to; receive a plurality of vehicle environment inputs, the inputs comprising a position in two dimensions for each of a plurality of objects located around a vehicle, each object located in one of four quadrants surrounding the vehicle; determine an object risk value for each of the objects by applying the set of rules to each of the objects, at least a plurality of the object risk values being non-zero, indicating the objects pose a risk to the vehicle; aggregate the object risk values in a front quadrant to generate a front quadrant risk value; aggregate the object risk values in a back quadrant to generate a back quadrant risk value; aggregate the object risk values in a left quadrant to generate a left quadrant risk value; aggregate the object risk values in a right quadrant to generate a right quadrant risk value wherein at least one of the front, back, left, and right quadrant risk values is determined by aggregating at least two of the non-zero object risk values; and control a driver assistance system of the vehicle based on the quadrant risks. - View Dependent Claims (16, 17, 18, 19)
