A driver torque estimation device includes: a transfer ratio variation device and a torsion bar; an electric motor; a torque sensor; an input shaft rotation acquisition unit configured to acquire the rotational angle of an input shaft of the transfer ratio variation device; and an electronic control unit configured to acquire the rotational angle of an output shaft of the transfer ratio variation device. The electronic control unit is configured to compute an estimated value of first disturbance. The electronic control unit is configured to compute an estimated value of second disturbance. The electronic control unit is configured to compute an estimated value of driver torque based on the torsion bar torque, the estimated value of the first disturbance, and the estimated value of the second disturbance.
