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.
Claims5
A wireless airbag control system comprising:
- a) a central master electronic control module having an RF transceiver and including a processor to selectively communicate prioritized messages to a plurality of slave nodes;
- b) a plurality of airbag devices capable of repeatable inflation and deflation, wherein each of said airbag devices is mounted to perform a controlled, repeatable operating function to deploy and retract an attached mechanical device;
- c) a plurality of slave nodes, each slave node being associated with one of said airbag devices, wherein each slave node further comprises an RF transceiver, a central processing unit, and a CAN controller;
- wherein each slave node further includes a terminating resistor;
- and wherein each slave node is connected to operate a plurality of associated airbag valve control devices to selectively allow air to enter and leave each airbag.
