An AI-based design of a driver information unit

An artificial intelligence-based approach to the design of a driver information unit (DUI) is described. The process layer used for direct control of effectors and output devices is realized as a computer system equipped with realtime operating system and appropriate software for handling the continuous flow of information from and to the environment. The discreet response layer (DRL) is used for processing symbolic, discrete information originating in the process layer. A symbolic characterization of environment condition is created in the process layer, and every change of this characterization causes a message to be sent to the DRL. The DRL is realized as a rule-based system. The reasoning layer is used for actual reasoning about the environment. The discreet response layer is not able to make decisions other than based on predefined set of behavior rules. When a need for more complex reasoning arises, it has to be realized by the reasoning layer equipped with more sophisticated algorithms. The result is sent back to the DRL for further processing.
