Abstract

A steering control apparatus is provided which more adequately detects a driver's operating state. A steered-angle command value calculation circuit (54) calculates a steered-angle command value (θt*) by adding a steering torque to a first assist component (Ta1*) that is a sum of a basic assist control amount (Tas*) and compensation components (a hysteresis control amount (Th*) and a damping control amount (Td*)). A steered-angle feedback control circuit (55) calculates a second assist component (Ta2*) by performing angle feedback control based on the steered-angle command value (θt*). A compensation control circuit (52) generates the hysteresis control amount (Th*) and the damping control amount (Td*) based on a determination flag generated by a hand release determination circuit (80) and indicating whether or not the steering state corresponds to a hand release state. The hand release determination circuit (80) determines whether or not the steering state corresponds to the hand release state based on signs of a steering angle (θs) calculated by a steering-angle calculation circuit (70), a steering angular velocity that is a differential value of the steering angle (θs), and a steering angle acceleration.
