Based on the result of determination by a friction transition state determination unit, an assist command value correction unit corrects a basic assist command value in such a way that the hysteresis width of steering torque at a time of turning steering increases; then, a current driving unit controls a motor current in such a way that the motor current coincides with a current command value obtained by correcting the basic assist command value by use of an assist command correction value.

Steering control apparatus

In an electric power steering device assisted by a brushless motor, an induced voltage from a brushless motor is detected when a main power supply is off. The motor is determined to be in a high rpm state when the induced voltage is in a first transient state from a voltage&#x2264;a high rpm detection threshold Th1 to a voltage&#x2265;Th1, thereby setting an intermittent excitation cycle of a revolution angle sensor connected to the motor to a short cycle. The motor is determined to be in a low rpm state when the induced voltage becomes a voltage&#x2265;a high rpm detection threshold Th2 after a wait period corresponding to an electrical angle between peaks or valleys of an output voltage has elapsed in a second transient state from a voltage&#x2265;Th1 to a voltage&#x2264;Th2, thereby setting the cycle to a long cycle.
