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 by quadrant to generate a set of quadrant risk values comprising a front risk value, a back risk value, a left risk value, and a right risk value, at least one of the quadrant risk values determined by aggregating the plurality of 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.

16. 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 by quadrant to generate a set of quadrant risk values comprising a front risk value, a back risk value, a left risk value, and a right risk value, at least one of the quadrant risk values determined by aggregating the plurality of non-zero object risk values; and control a driver assistance system of the vehicle based on the quadrant risks. - View Dependent Claims (17, 18, 19, 20)
