摘要： PROBLEM TO BE SOLVED: To provide an electric power steering device for improving traveling stability and steering performance.SOLUTION: An EPS-ECU determines whether a steering wheel 2 is a steering increase state (that is, the forward side) in a Step S4, and sets steering increase time target steering torque Ttg as a target steering torque base value Ttb in a Step S5 when this determination is Yes. When a determination of the Step S4 is No, the EPS-ECU determines whether the steering wheel 2 is a steering return state (that is, the return side) in a Step S6, and sets steering return time target steering torque Ttr as the target steering torque base value Ttb in a Step S7 when this determination is Yes. When a determination of the Step S6 is also No (that is, when the steering wheel 2 is a nonrotating steering holding state), the EPS-ECU sets steering holding time target steering torque Tth as the target steering torque base value Ttb in a Step S8.

摘要： PROBLEM TO BE SOLVED: To provide an electric power steering device that achieves improvement in steerability during collision avoidance or the like.SOLUTION: The electric power steering device is configured as follows. An EPS-ECU sets a first normal-time steering angular velocity difference DTω1 by subtracting a first normal-time target steering angular velocity KTω1 from an actual steering angular velocity ω in a step S24, and also, sets a first emergency steering angular velocity difference DMω1 by subtracting a first emergency target steering angular velocity KMω1 from the actual steering angular velocity ω in a step S25. Next, the EPS-ECU determines whether a collision avoidance steering flag Fes is 1 in the step S26. If the determination is No (namely, if it is in a normal steering state), the EPS-ECU adopts the DTω1 as an additional-steering-input side steering angular velocity difference Dω1 in a step S27. On the other hand, if the determination in the step S26 is Yes (namely, if it is in a collision avoidance steering state), the EPS-ECU adopts the DMω1 as the additional-steering-input side steering angular velocity difference Dω2 in the step S27.
