Experimental Steer-by-Wire Vehicle
Drive-by-wire systems have many advantages over conventional automotive
steering, braking, and throttle mechanisms. By electronically actuating
the throttle, brakes, and steering, driving inputs can be fully integrated
with vehicle safety systems and thus improve the safety benefits of such
systems. However, the absence of conventional mechanical associations
between the driver and the vehicle raises some new questions regarding the
nature of interactions that occur between driver, vehicle, and environment
in a drive-by-wire vehicle.
As a first step toward investigating the potential of by-wire technology,
a test vehicle has been equipped with complete
steer-by-wire capability. The steer-by-wire platform will serve a dual
purpose: in addition to assisting in the development of theories
relating the driver to steering system dynamics, it will be used as a
testbed for experimentally validating theoretical work in
