Abstract: A rotation angle detection device includes a correction-object driven gear that is a driven gear meshing with a main driving gear, a first sensor that is configured to generate an electrical signal based on rotation of the correction-object driven gear, and an electronic control unit that computes a driven-side rotation angle based on the electrical signal. The electronic control unit is configured to store a correction angle used to correct the driven-side rotation angle when computing the driven-side rotation angle. The correction angle is a predetermined deviation in a predetermined angle domain obtained as an average value in which deviations of the number equal to the integer and corresponding to a same relative rotation angle is averaged, so as to be deviation in an angle domain of 0 to 360 degrees.

Abstract: A torque sensor device for detecting a torque applied to a shaft, includes a magnetic arrangement, a stator arrangement and a magnetic sensor arrangement. The magnetic arrangement is configured for generating at least one magnetic field. A magnetic flux can be generated in the stator arrangement. The magnetic arrangement and the stator arrangement are movable relative to each other in the circumferential direction. The magnetic arrangement and the stator arrangement are arranged relative to each other so that, by a relative movement between the magnetic arrangement and the stator arrangement in the circumferential direction about a center axis of the torque sensor device, a first magnetic flux with a first magnetic flux direction and a second magnetic flux with a second flux direction opposite to the first flux direction can be generated in the stator arrangement.

Based on a first sine signal representing sin(θos+Δθ) and a first cosine signal representing cos(θos+Δθ) in accordance with a rotation angle(θis) of a first multipolar ring magnet that synchronously rotates with an input shaft from between the coaxially arranged input shaft and an output shaft, and based on a second sine signal representing sin θos and a second cosine signal representing cos θos in accordance with a rotation angle(θos) of a second multipolar ring magnet that synchronously rotates with the output shaft, sin Δθ and cos Δθ are calculated in accordance with a relative angle(Δθ) between the input shaft and the output shaft, and from Δθ=arctan(sin Δθ/cos Δθ), the relative angle(Δθ) is calculated.
