A driver assistance system with an architecture of general use for applications related to driver assistance, passenger safety and comfort and communication with external systems, e.g. for diagnosis and maintenance purposes, comprises (in one embodiment): a first interface for sensing external signals coming from the environment of a vehicle, a second interface for sensing internal signals of the vehicle, a first subsystem for fusing the output signals of the first interface and the second interface in order to generate a representation of the vehicle's environment, a second subsystem for modeling the current state of the vehicle being provided with the output signals of the first subsystem, a third subsystem for modeling the behavior of a driver, a fourth subsystem for interpreting the current scene represented by the first subsystem in order to determine characteristic states of the current external situation of the vehicle, and a fifth subsystem that generates stimuli for the actuators of the vehicle and/or the driver based on the output signals of the second, the third and the fourth subsystem.

What is claimed is: 1. A driver assistance system comprising:a first interface for sensing external signals received from an environment of a vehicle and generating a first interface output signal, the first interface comprising projective sensors and non-projective sensors,a second interface for sensing internal signals of the vehicle and generating a second interface output signal,a first subsystem comprisingan information fusion module, a vehicle environment representation module, a vehicle environment interpretation module, and a knowledge base for storing representations of detectable object associated attributes,wherein the information fusion module identifies an object based on the first interface output signal and provides the identity of the object to the knowledge base,wherein the knowledge base receives said identity of the object and provides attribute signals representing at least one object attribute of the identified object to the vehicle environment representation module, andwherein the vehicle environment representation module generates a central model of the vehicle environment comprising at least one representation of an object, wherein each representation of an object comprises the identity of the object and at least one object attribute,wherein the vehicle environment interpretation module sends data to the vehicle environment representation module to guide a filtering process that filters identified objects from the central model of the vehicle environment based on relevance,a second subsystem for modeling a current internal state of the vehicle based on the second interface output signal,a third subsystem for modeling a driver intention,a fourth subsystem for analyzing the central model of the vehicle environment represented by the first subsystem in order to distinguish external environmental conditions relevant to the vehicle, anda fifth subsystem for ranking a hierarchy of action signals, the action signals generated based on the output signals of the second, the third and the fourth subsystems, wherein the ranking is based on the modeled driver intention, and for generating stimuli for an actuator of the vehicle or the driver based on a highest ranked action signal in the hierarchy.
