Abstract

Provided is a steering control apparatus capable of executing driving assistance control even during execution of 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 from the start of execution of the rotation angle sensor-less control and when the driving assistance control is executed based on a command value (S*) from a higher-level control apparatus, a second pre-addition angle (β2) that is based on the command value (S*) is used as a second addition angle (Δθm2) in place of a first pre-addition angle (β1) that is based on a steering torque (Trq). Therefore, even in a situation in which the steering torque (Trq) 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 (Δθm2). Then, driving of the motor is controlled based on the calculated estimated electrical angle.
