Driver assistance system
First Claim
1. A driver assistance system comprising:
- a first interface for sensing external signals received from an environment of a vehicle, a second interface for sensing internal signals of the vehicle, a first subsystem for fusing 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 a current state of the vehicle being provided with the output signals of the second interface, a third subsystem for modeling a behavior of a driver, a fourth subsystem for interpreting a current scene represented by the first subsystem in order to determine characteristic states of a current external situation of the vehicle, and a fifth subsystem that generates stimuli for at least one of actuators of the vehicle or the driver based on the output signals of the second, the third and the fourth subsystems.
