Patent number: 11731694Abstract: In a steering control apparatus, a reaction force torque command value is calculated so that a detection value of a torque sensor follows a target value obtained by adding at least a viscosity command value and a return command value to a steering torque command value, and an electric current that flows to a reaction force rotary electric machine is controlled based on the reaction force torque command value. Whether a steering state is a turning state or a returning state is determined by comparing a physical quantity corresponding to an output torque of a reaction force device and the detection value of the torque sensor. Characteristics of one or more of a reaction force amount operation, a viscosity amount operation, and a return amount operation are made differ between the turning state and the returning state.Type: GrantFiled: July 16, 2020Date of Patent: August 22, 2023Assignee: DENSO CORPORATIONInventor: Takashi Suzuki
