Abstract: A driver control input device includes left and right control posts each having a hand grip. The control posts are movable forwardly and rearwardly and are sufficiently linked together such that forward movement of one control post will result in an equal and opposite rearward movement of the other control post to facilitate sending non-mechanical steering signals to a steer-by-wire system to which the control input device is attached. Accelerator demand input mechanisms and braking demand input mechanisms may also be positioned on the hand grips for generating non-mechanical acceleration and braking signals.
