Abstract

A wireless airbag control system includes a central master electronic control module having an RF transceiver. One or more slave nodes are provided, each slave node being associated with an airbag that is mounted to perform an operating function with respect to a mechanical device. Each slave node further includes an RF transceiver, a central processing unit and a CAN controller. Two-way communication is shared between the slave nodes and the master electronic control module on a prioritized message basis.

Claims

1. A wireless airbag control comprising:

a) a central master electronic control module having an RF transceiver;

b) a plurality of slave nodes, each slave node being associated with an airbag that is mounted to perform an operating function with respect to a mechanical device; and

wherein each slave node further comprises an RF transceiver, a central processing unit, and a CAN controller.

2. A wireless airbag control system as in claim 1 wherein each slave node further comprises a terminating resistor.

3. A wireless airbag control system as in claim 1 wherein each slave node is connected to operate one or more associated airbag valve control devices.

4. A wireless airbag control system as in claim 3 wherein each slave node is connected to operate a plurality of airbag valve control devices.

5. A wireless airbag control system as in claim 1 wherein each slave node is connected to one or more pressure sensors.

6. A wireless airbag control system as in claim 3 wherein each slave node is connected to one or more pressure sensors.

7. A wireless airbag control system as in claim 5 wherein each slave node is connected to a plurality of pressure sensors.

8. A wireless airbag control system as in claim 4 wherein each slave node is connected to a plurality of pressure sensors.

9. A wireless airbag control system as in claim 1 wherein each slave node is connected to a sensor for determining airbag position or force being applied.

10. A wireless airbag control system comprising:

a) a central master electronic control module having an RF transceiver;

b) one or more slave nodes, each slave node being associated with an airbag that is mounted to perform an operating function with respect to a mechanical device;

c) wherein each slave node further comprises an RF transceiver, a central processing unit and a CAN controller

(d) wherein each slave node is connected to operate one or more associated airbag valve control devices and connected to receive signals from one or more pressure sensors.
