Abstract: Provided is a steering control unit for improving influence of fluctuations in an estimated electrical angle on steering feel. A steering control unit includes a microcomputer that performs sensorless control of the driving of a motor by using an estimated electrical angle estimated by calculation. The microcomputer calculates the estimated electrical angle from a value that is obtained by selectively accumulating a first additional angle or a second additional angle. The microcomputer adjusts a vibration component of fluctuations in the estimated electrical angle by varying the amount of change in the first additional angle and the second additional angle.

Abstract: Provided is a steering control apparatus capable of executing driving assistance control even during rotation angle sensor-less control. When an induced voltage generated in a motor is equal to or lower than a threshold voltage at an early stage of execution of the rotation angle sensor-less control and when the driving assistance control is executed based on a command value from a higher-level control apparatus, a second pre-addition angle that is based on the command value is used as a second addition angle in place of a first pre-addition angle that is based on a steering torque. Therefore, even in a situation in which the steering torque is not detected due to, for example, execution of driving assistance, an estimated electrical angle of the motor is calculated by integrating the second addition angle. Then, driving of the motor is controlled based on the calculated estimated electrical angle.

Abstract: A steering control unit includes a microcomputer that performs sensorless control of driving of a motor by using an estimated electrical angle estimated by calculation. The microcomputer has a first estimation calculation state and a second estimation calculation state. In the first estimation calculation state, the microcomputer calculates the estimated electrical angle from a value obtained by accumulating a first additional angle calculated by a first additional angle calculation circuit on the basis of a voltage induced in the motor. In the second estimation calculation state, the microcomputer calculates the estimated electrical angle from a value obtained by accumulating a second additional angle calculated by a second additional angle calculation circuit that performs torque feedback control that causes steering torque to follow a target torque value. In a low steering velocity state, the microcomputer calculates the estimated electrical angle in the second estimation calculation state.

Abstract: In a motor control unit, a current-carrying failure detection unit determines a first determination condition and a second determination condition. The current-carrying failure detection unit measures a duration of a state where the first determination condition is satisfied, and a duration of a state where the second determination condition is satisfied. When the first or second duration exceeds a predetermined reference period, the current-carrying failure detection unit determines that a current-carrying failure has occurred.
