ABSTRACT:
A voice warning system for an automotive vehicle automatically adjusts voice volume in accordance with the urgency or importance of a vocal warning concerning engine operating conditions, and with car radio volume as selected by the vehicle user. A plurality of sensors output signals in response to abnormal engine or vehicle conditions. A volume memory recognizes and stores the current volume setting of the car radio. A voice volume selector produces a voice volume signal according to the volume memory value, and according to which sensor signal is received. An electronic volume controller responds to the voice volume signal to set the volume of a voice warning signal selected by a voice output selector in response to the received sensor signal.
