Abstract

An onboard, multi-channel vehicle communication system uses a wireless hand-held control and display unit which can be removed from a charging cradle and moved about the interior of an automotive vehicle. An alarm function reminds the user of the hand-held unit that he/she is leaving the immediate area of the vehicle.

Claims

1. A data communication system for an automotive vehicle having an onboard battery comprising:

(a) a fixed-base data receiving and processing unit adapted to be installed on the vehicle and connected to the vehicle battery;

said fixed-base unit including;

1. a plurality of inputs for data to be processed;

2. an output for processed data; and

3. a first short-range data transceiver connected to the output;

(b) a wireless, hand held control/display unit having;

1. a second short-range data transceiver linkable to the first transceiver to communicate displayable data and control data therebetween;

2. a display for displaying data received by the second transceiver;

3. a rechargeable battery; and

4. a video signal portion, the video signal portion being linked to the second transceiver for receiving output signals in the form of displayable data therefrom, the video signal portion being connected to the display; and

(c) a holder/recharger adapted to be installed on the vehicle to receive the hand-held unit;

said holder/recharger and said hand-held unit having complemental contacts thereon for recharging said hand-held unit from the vehicle battery.

2. A system as defined in claim 1 wherein said hand-held control/display unit further comprises an audio signal portion and a speaker, the audio signal portion being linked to the second transceiver and connected to the speaker.

3. A system as defined in claim 1 wherein said plurality of inputs includes a RF input channel for receiving data.

4. A system as defined in claim 1 further comprising one or more displayable data sources selected from a group consisting of a tire pressure transducer, an oil pressure transducer, a radio signal source, a video signal source, an onboard multiple program instructional data source and an entertainment data source.

5. A system as defined in claim 1 wherein said wireless hand-held control/display unit is of such size and weight as to be readily held, manipulated and transported by an ordinary adult human.

6. A data communication system for an automotive vehicle having an onboard battery comprising:

(a) a fixed-base data receiving and processing unit adapted to be installed on the vehicle and connected to the vehicle battery;

said unit including;

1. a plurality of inputs for data to be processed;

2. an output for processed data; and

3. a first short-range data transceiver connected to the output;

(b) a wireless, hand-held control/display unit having;

1. a second short-range data transceiver linkable to the first transceiver to communicate displayable data and control data therebetween;

2. a display for displaying data and/or received by the second transceiver; and

3. a rechargeable battery;

(c) a holder/recharger adapted to be installed on the vehicle to receive the hand-held unit;

said holder/recharger and said hand-held unit having complemental contacts thereon for recharging said hand-held unit from the vehicle battery; and

(d) means for generating an audible alarm for said wireless unit whenever it is beyond the operating range of the transceiver link.

7. A data communication system for an automotive vehicle having an onboard batten comprising:

(a) a fixed-base data receiving and processing unit adapted to be installed on the vehicle and connected to the vehicle battery;

said unit including;

1. a plurality of inputs for data to be processed;

2. an output for processed data and

3. a first short-range data transceiver connected to the output;

(b) a wireless, hand-held control/display unit having;

1. a second short-range data transceiver linkable to the first transceiver to communicate displayable data and control data therebetween;

2. a display for displaying data and/or received by the second transceiver; and

3. a rechargeable battery;

a holder/recharger adapted to be installed on the vehicle to receive the hand-held unit;

said holder/recharger and said hand-held unit having complemental contacts thereon for recharging said hand-held unit from the vehicle battery; and

(d) means in said fixed base unit for triggering the generation of an audible locator signal from said wireless unit.
