1. A steering apparatus for use in a vehicle having steerable wheels, an actuatable steering motor connected to the steerable wheels, and an actuator for actuating the steering motor in response to a steering signal, said apparatus comprising:

  • a support;

    a steering input shaft rotatable relative to said support by a vehicle operator;

    first sensing means for sensing the rotational position of said input shaft and for producing an electrical signal indicative thereof;

    second sensing means for sensing the position of the steerable wheels and for producing an electrical signal indicative thereof;

    electromagnetic friction brake means connected to said input shaft and said support for providing a controllable amount of mechanical resistance to relative rotation between said steering input shaft and said support responsive to an electrical control signal; and

    control means for (i) generating said steering signal to actuate the steering motor and (ii) generating said electrical control signal responsive to the electrical signals from said first sensing means and said second sensing means.
