Abstract:
A current command value calculation circuit includes an end abutment determination circuit and a guard processing circuit. When a decrease amount of an induced voltage value within a predetermined time is equal to or larger than a predetermined decrease amount in the state that a steering torque is equal to or larger than a predetermined torque, the end abutment determination circuit determines that the end abutment occurs. When a determination signal indicating that the end abutment state does not occur is input, the guard processing circuit outputs an elemental current command value directly as a q-axis current command value. When a determination signal indicating that the end abutment state occurs is input, the guard processing circuit outputs, as the q-axis current command value, a value obtained by limiting the elemental current command value so that its absolute value is equal to or lower than a predetermined limit current value.

Claim (Index 3):
The steering control apparatus according to  claim 1 , further comprising a rotation angle estimation circuit configured to calculate an estimated electrical angle of the motor based on the induced voltage value, wherein\n the control circuit is configured to execute sensorless control for controlling the operation of the motor based on the estimated electrical angle calculated by the rotation angle estimation circuit, and the end abutment determination circuit is configured to make end abutment determination based on the steering torque and the induced voltage value during execution of the sensorless control.
