STEERING CONTROLLER AND STEERING CONTROL METHOD

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.
