Abstract
A steering torque shift control amount calculation unit () calculates the steering torque shift control amount (εts) by multiplying the basic shift amount (εts_b) used as the basic compensation component by the transition coefficient (Kss). Then, the steering torque shift control amount (εts) is subjected to the low-pass filter process in an abrupt change prevention processing unit (). An abrupt change prevention processing unit () is provided in the steering torque shift control amount calculation unit (). The transition coefficient (Kss) is subjected to the low-pass filter process in the abrupt change prevention processing unit (). The cutoff frequency of the low-pass filter that forms the abrupt change prevention processing unit () is set to a value lower than the cutoff frequency of the low-pass filter that forms the abrupt change prevention processing unit () that executes the low-pass filter process on the torque shift control amount (εts).
