摘要： A vehicle steering device includes a driver torque estimation unit (51) that includes a driver torque estimation observer, a low-pass filter (52), and a hands-on/off determination unit (53). The driver torque estimation observer estimates driver torque (Tsw) applied to a steering wheel by a driver on the basis of a detected value that includes at least torsion bar torque (Ttb) detected by a torque sensor (11) and the rotational angle of an electric motor detected by a rotational angle sensor (25). The low-pass filter (52) performs a low-pass filtering process on the estimated driver torque. The hands-on/off determination unit (53) determines whether in a hands-on state or a hands-off state on the basis of the driver torque after being subjected to the low-pass filtering process.
