Abstract
A variable road feedback device (20) for a steer-by-wire system (50) comprises a housing (31) that contains a magnetorheological fluid (32), a magnetic field generator (34) for generating a variable magnetic field within the housing (31) in order to vary the viscous resistance of the magnetorheological fluid (32) therein, and a rotor (24) rotatably mounted within the housing (31) that rotates through the magnetorheological fluid (32) and is responsive to the variable viscous resistance thereof.
