ABSTRACT:
An adaptive learning system for adapting the frequency setting and volume level of a vehicle radio in response to a vehicle operator's preference of radio stations and volume levels for a particular time of day. A microprocessor is responsive to the frequency settings and volume level of the radio as set by the vehicle operator with respect to specific time intervals of the day. The microprocessor will establish a list of priority radio stations dependent on how often the vehicle operator selects the radio frequencies during each specific interval and an average volume level of the radio. The system will then automatically set the radio frequency and volume level based on the vehicle operator's priorities at vehicle start-up with respect to the current time of day.
