Abstract

A voice message system for motor vehicles includes an audio reproduction and recording system, and a control that interfaces the audio system with the vehicle function controls. Preferably, an ignition switch sensor signal received at the control initiates a command for playback of current time or periodic time designated messages. The control may also interface with a sensor signal responsive to an air bag diagnostic switch for actuating the recording of vocalized instructions or comments. In addition, a single actuator for immediate recording capability, as well as a microphone for receiving vocalized messages are conveniently packaged in the steering control mechanism.

Claims

1. A method for operating a vehicle message system including a vehicle audio system having record, store and replay audio function modes, the method comprising:

recording an audio message by reproducing a vocally intoned output as a message signal in the record functional mode of said vehicle message system;

storing said message signal;

retrieving said message signal in response to a first predetermined actuator;

reproducing said audio message on said vehicle audio system from said retrieved message signal;

wherein said actuator comprises an ignition switch and said retrieving step comprises closing said ignition switch; and

wherein said reproducing step comprises passively reproducing said audio message.

2. The invention as defined in claim 1 wherein said recording step is an automatic response to actuating an air bag activation switch.

3. The invention as defined in claim 1 and further comprising associating a time specific designation with said message signal.

4. The invention as defined in claim 3 wherein said time specific designation is a current time designation.

5. The invention as defined in claim 3 wherein said time specific designation is a periodic time designation and wherein said retrieving step comprises matching a clock pulse designation to said time specific designation.

6. The invention as defined in claim 1 wherein said reproducing step comprises serially reproducing said message signal a plurality of times, each time occurring at each sequential operation of said actuator.

7. The invention as defined in claim 1 and further comprising saving said retrieved signal for reproducing said audio message at the next sequential operation of said actuator.

8. The invention as defined in claim 7 and further comprising retrieving the saved signal and reproducing said audio message from said saved signal.

9. The invention as defined in claim 7 and further comprising passively deleting said message after a predetermined number of reproducing steps have occurred.

10. A method for operating a vehicle message system including a vehicle audio system having record, store and replay audio function modes, the method comprising:

recording an audio message by reproducing a vocally intoned output as a message signal in the record functional mode of said vehicle message system;

storing said message signal;

retrieving said message signal in response to a first predetermined actuator;

reproducing said audio message on said vehicle audio system from said retrieved message signal; and

wherein said recording step is an automatic response to actuating an air bag activation switch.

11. An audio system enhancement for a vehicle audio system having an audio message recorder, an audio message player and a command module including a microcomputer and an operator terminal, the enhancement comprising:

an actuator for single engagement initiation of said recorder to record an audio message;

an address designator for including a time designation with said message;

a store memory for storing the message upon completion of recording;

a store memory for saving said message until said predetermined time designation;

a retriever for selecting and delivering a stored message to said player including a first predetermined actuator for automatically operating said player in passive response to a vehicle function; and

a storer for automatically storing said message until said actuator has functioned a second predetermined number of times.

12. The invention as defined in claim 11 wherein said first predetermined actuator comprises a vehicle function switch.

13. The invention as defined in claim 12 wherein said actuator comprises an ignition switch.

14. The invention as defined in claim 12 wherein said actuator comprises an air bag activator switch.

15. An automatic audio reminder system for a motor vehicle having a steering wheel, and having an audio recording and playback system including:

an actuator on said steering column for single engagement initiation of recording an audio message;

storage means for automatically retaining said message for audio playback;

a playback initiator comprising a first predetermined vehicle function actuator and a control for responding to said predetermined vehicle function actuator by commanding said audio system to play back said audio message;

a counter for determining and identifying with an audio message signal the number of times said audio message has been played; and

a storer for returning said identified audio message signal to storage unless said identified audio message signal has been played a predetermined number of times.

16. The invention as defined in claim 15 and further comprising a save condition signal actuator for associating said audio message with a periodic time designation.

17. The invention as defined in claim 15 and further comprising an emergency signal actuator for associating said audio message with an air bag diagnostic switch actuation.
