The present invention provides an electronic control device, a control method, and an electronic control program, which can not only improve the responsiveness of the steering wheel when the steeringwheel is operated, but also suppress the vibration of the steering wheel caused by the variation of the steering torque when the steering wheel is held. The ECU (4) is equipped with a torque current control unit (7), which sets the first current command value to be supplied to the motor (2) based on the value of the steering torque; a differential control unit (8), which calculates the steering the differential value of the torque, that is, the torque differential value, and the second current command value is set based on the torque differential value and the rotation speed of the motor (2);and a command value calculation unit (10), which calculates the motor current command value supplied to the motor (2).
本发明提供一种电子控制装置、控制方法及电子控制程序,其既可在方向盘的操纵时提高操纵的响应性,又可在方向盘的保持时抑制由操纵转矩的变动引起的方向盘的振动。ECU(4)具备:转矩电流控制部(7),其根据操纵转矩的值,设定应向电动机(2)供给的第一电流指令值;微分控制部(8),其计算出操纵转矩的微分值即转矩微分值,并根据转矩微分值及电动机(2)的旋转速度,设定第二电流指令值;以及指令值计算部(10),其计算出应向电动机(2)供给的电动机电流指令值。
