Abstract

A steering apparatus includes: a first shaft (8) which is coupled to a steering wheel (2); a torsion bar (10); a second shaft (9) which is coupled to the first shaft (8) through the torsion bar (10); a torsion bar torque detection unit (11) detecting a torsion bar torque (T tb ) which is applied to the torsion bar (10); and an electronic control unit configured to estimate a driver torque (T d ) which is applied to the steering wheel by a driver. The electronic control unit is configured to: i) compute a steering wheel rotation angle (¸ sw ) which is a rotation angle of the steering wheel (2); and ii) compute a value including an added value, as the driver torque (T d ), the added value being a value resulting from adding the torsion bar torque (T tb ), a steering wheel inertia torque compensation value, and a gravity torque compensation value (T g ).
