Patent number: 8606462Abstract: There is provided a electric power steering device which can perform torque control through a simple arithmetic process using a synchronous reluctance motor having a nonlinear current/torque characteristic. A target torque is transmitted from an EPS control unit 41 to a motor control unit 51. The motor control unit 51 calculates a target-current effective value I and a target-current phase ? from the input target torque. Based on the calculated target-current effective value I and target-current phase ?, calculation is changed whether to perform calculation so that the maximum torque (the maximum torque obtainable at the minimum current effective value) can be obtained, or to perform calculation so that the maximum output (the maximum output obtainable at the minimum current effective value) can be obtained in accordance with a duty ratio of an output by a PWM converting unit 57 comprising a three-phase inverter.Type: GrantFiled: September 2, 2009Date of Patent: December 10, 2013Assignee: Honda Motor Co., Ltd.Inventor: Yasuhiro Nakano
