摘要： A steering controller (40) is configured to execute a first operation process for, when an angle command value is not input from outside of the steering controller, calculating a first torque command value corresponding to a steering-side operation amount and operating a drive circuit of an electric motor (32) to adjust torque of the electric motor to the first torque command value. The steering controller (40) is further configured to execute a second operation process for, when the angle command value is input from the outside of the steering controller, calculating a second torque command value corresponding to at least an angle-side operation amount of the steering-side operation amount and the angle-side operation amount and operating the drive circuit of the electric motor (32) to adjust the torque of the electric motor to the second torque command value.

摘要： A steering controller (40) is configured to execute a torque control process for calculating a steering-side operation amount, an angle feedback control process for calculating an angle-side operation amount, and an operation process for operating a drive circuit of an electric motor (32) to adjust torque of the electric motor to a torque command value. The steering controller (40) is further configured to execute a switch process for switching, when determining that a controllability of the electric motor is less than or equal to a predetermined efficiency, the torque command value from a value based on the angle-side operation amount to a value based on the steering-side operation amount instead of the angle-side operation amount.

摘要： A motor control device includes a controller (40) configured to calculate a current command value corresponding to torque that should be generated by a motor (31), divide the calculated current command value into individual current command values for coil groups (52,53), control power feeding to the coil groups independently for each of the coil groups based on a corresponding one of the individual current command values, set, for each one of the coil groups, an upper limit value of a corresponding one of the individual current command values and, when the individual current command value for any one of the coil groups is limited to a value that is smaller than a corresponding one of the upper limit values, supplement an amount limited in the individual current command value by increasing the individual current command value for at least a remaining one of the coil groups.
