The purpose of the present invention is to provide a calculation program, a calculation method, and a three-phase motor system which can appropriately detect, even with one shunt resistance, the current flowing in each phase of a three-phase AC motor. A calculation program according to the present disclosure causes a computer to execute: a step for detecting a total current, which is the total value of alternating current flowing in each of the three phases of a three-phase AC motor (110); and a step for calculating, on the basis of the total current and the duty ratio of each phase, a phase current for each phase, i.e. the alternating current flowing in each of the three phases of the three-phase AC motor (110).

According to the present invention, undershoot is suppressed while a computational load is restricted. This motor control device controls a motor (10), and includes: a comparing unit (20) for comparing a measured rotational speed, which is a measured value of the rotational speed of the motor (10), and a target rotational speed, which is a target value of the rotational speed of the motor (10); and a current control unit (26) for controlling a current value applied to the motor (10), on the basis of the comparison result obtained by the comparing unit (20). If the measured rotational speed is lower than the target rotational speed, the current control unit (26) causes a current having a current value with which the rotational speed of the motor (10) can reach the target rotational speed to be applied to the motor (10), and if the measured rotational speed is equal to or greater than the target rotational speed, the current control unit (26) stops the application of the current to the motor (10).

In the present invention, an electric power steering device (100) comprises: a first urging mechanism (60); and a second urging mechanism (70). The first urging mechanism (60) includes a first yoke (61) that abuts against a rack shaft (12) and is movable within a first accommodation section (17d) following the movement of the rack shaft (12). The second urging mechanism (70) includes a second yoke (71) that abuts against the rack shaft (12) and is movable within a second accommodating section (17e) following the movement of the rack shaft (12). Movement of the first yoke (61) and the second yoke (71) is restricted by the rack housing (17) as the amount of movement of the rack shaft (12), which steers wheels (2), increases, making it impossible to follow the rack shaft (12). The timings at which the first yoke (61) and the second yoke (71) start to slide on the rack shaft (12) differ from each other.

[Problem] To provide a valve and a shock absorber that are inexpensive and provide satisfactory assembling properties. [Solution] A valve (V) according to the present invention comprises: an annular valve body (14); spacers (16, 17) each of which is laminated on the annular valve body (14) and serves as a bending fulcrum for the free end of the annular valve body (14); and valve stoppers (13, 15) each of which faces the spacer (16, 17) side of the annular valve body (14) in the axial direction and regulates the bending of the annular valve body (14) when the annular valve body (14) is bent to abut against the valve stopper (13, 15). The valve stoppers (13, 15) comprise: rings (131, 151) each of which has an axial thickness smaller than that of the spacer (16, 17) and is disposed in the inner periphery or outer periphery of the spacer (16, 17); and laminated annular plates (132, 152) laminated to the spacers (16, 17), respectively.

The present invention inhibits a decrease in inference accuracy of a road surface condition. This calculation device comprises: a first determination unit (34) that, on the basis of behavior information detected in a predetermined position and first reference behavior information detected in a first region overlapping the predetermined position, determines whether the behavior information detected in the predetermined position corresponds to the first reference behavior information; a second determination unit (36) that, if the behavior information detected in the predetermined position is determined not to correspond to the first reference behavior information, on the basis of behavior information detected in a second region encompassing the entire first region and broader than the first region and second reference behavior information detected in the second region, determines whether the behavior information detected in the second region corresponds to the second reference behavior information; and a learning unit (30) that causes an AI model to machine-learn. If the behavior information detected in the second region is determined not to correspond to the second reference behavior information, the learning unit (30) updates the AI model with the behavior information detected in the second region as teacher data.
