Abstract
A driver assistance system takes as input a number of different types of vehicle environment inputs including positions of objects in the vehicle's environment. The system identifies possible outcomes that may occur as a result of the positions of the objects in the environment. The possible outcomes include predicted positions for the objects involved in each outcome. The system uses the inputs to determine a likelihood of occurrence of each of the possible outcomes. The system also uses the inputs to determine a current risk value for objects as well as predicted risk values for objects for the possible outcomes. A total risk value can be determined by aggregating the current and predicted risk values of an object weighted by the likelihood of occurrence. Total risk values for objects can be used to determine how the driver assistance system responds to the inputs.
