A steering control device configured to control a steering device includes a control unit. The control unit is configured to calculate a torque command value which is a target value of the motor torque based on execution of angle control for adjusting a convertible angle which is able to be converted to a rotation angle of the motor to a target angle; calculate the motor control signal based on the torque command value; and change a control gain which is used for the angle control based on a change of a factor influencing a behavior of a vehicle in response to steering.

Steering control device

The electric power steering apparatus according to the present disclosure includes a steering assist mechanism and a controller. The steering assist mechanism is driven by a motor and assists operation of a steering wheel by a driver. The controller acquires the position of the steering wheel and sets a target value of a steering reaction torque acting on the steering wheel. Then, the controller calculates a position target of the steering assist mechanism based on the position of the steering wheel and the target value of the steering reaction torque, and controls the motor of the steering assist mechanism according to the position target of the steering assist mechanism.

Electric power steering apparatus

A steering system steers wheels of a vehicle through a shift of a steering shaft. The steering system includes: an electric motor; transmission device that transmits an output of the electric motor to the steering shaft; and a malfunction detector that detects a malfunction of the transmission device based on a rotational angle of the electric motor and a shift distance of the steering shaft.
