Abstract:
A connection system for communicating multiple signals between a steering wheel and a steering column of a vehicle over a single wire, comprising:a signal line for providing a single line connection between a steering wheel side and a steering column side in a vehicle, said signal line having a steering wheel end and a steering column end; a switching device comprising multiple inputs, a switch enable corresponding to each input, and an output connected to the steering wheel end of the signal line; a first input device having a plurality of switches connected to a first input of the switching device, wherein activation of each of the plurality of switches outputs a unique predetermined output voltage, corresponding to each of the plurality of switches, to the first input of the switching device; a second input device having a plurality of switches connected to a second input of the switching device, wherein activation of each of the plurality of switches outputs a unique predetermined output voltage, corresponding to each of the plurality of switches, to the second input of the switching device; and a timing generator connected to the switching device having multiple outputs that are toggled one at a time, each connected to a separate switch enable of the switching device, wherein the timing generator activates each switch of the switching device one at a time to allow the output from each of the plurality of switches to pass to the steering wheel end of the signal line.
