Abstract: An ECU controls a motor including a first coil group and a second coil group. The ECU calculates a first torque command value and a second torque command value. The ECU uses a first differential torque, which is the difference between a first theoretical output torque and a first predictive output torque, to correct the second torque command value for the second coil group. The ECU uses a second differential torque, which is the difference between a second theoretical output torque and a second predictive output torque, to correct the first torque command value for the first coil group. The ECU uses a corrected first torque command value to control power feeding to the first coil group and uses a corrected second torque command value to control power feeding to the second coil group.

Abstract: A method in which a continuous estimation of the intermediate friction rate is carried out, allowing the integration of the method into a general friction compensation method so as to continuously improve the feel on the steering wheel, particularly for speeds below a determined threshold. Also, a method for friction compensation in an electrical power steering system, characterised in that the compensation method takes into account a continuous estimation of the intermediate friction rate obtained by the estimation method.

Abstract: A steering controller includes processing circuitry configured to execute a first operation process that, when an angle command value is not input from outside of the processing circuitry, calculates a first torque command value corresponding to a steering-side operation amount and operating a drive circuit of an electric motor to adjust torque of the electric motor to the first torque command value. The processing circuitry is further configured to execute a second operation process that, when the angle command value is input from the outside of the processing circuitry, calculates 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 to adjust the torque of the electric motor to the second torque command value.
