DEVICE FOR CONTROLLING MOTOR-DRIVEN POWER STEERING DEVICE

摘要

There is provided a control device for a motor-driven power steering device for applying a steering auxiliary force by an n-phase motor to a vehicle steering system. The control device includes at least (n - 1) current detection means for detecting respective currents Im (m = 1, 2, ..., n) of the motor; current instruction value calculation means for outputting the current instruction value Imref of each phase; and n current control means. Each phase current is controlled by the current control means inputting the current instruction value Imref of each phase and the each phase current Im.
