A motor device includes a motor and a motor control device. The motor control device includes a board attached to an end portion of the motor, and a cover that covers the board. The motor has a motor body and a connector assembly. The board has an extending portion that overlays the connector assembly. The extending portion has terminal connecting portions to which terminals, held by the connector assembly, are connected. The cover has a first projecting portion that projects from an inner face of the end wall thereof toward the board. The first projecting portion comes into contact with a region of the board adjacent to the terminal connecting portions before the terminal comes into contact with the end wall of the cover, when the end wall of the cover is deflected in a direction closer the board.
A motor control device includes: an assist torque command value generation unit that generates an assist torque command value using steering torque; a manual steering command value generation unit that generates a manual steering command value using the steering torque and the assist torque command value; an integrated angle command value calculation unit that calculates an integrated angle command value by adding the manual steering command value to an automatic steering command value for driving assist; and a switching unit that switches between a first control mode in which an electric motor is controlled based on the assist torque command value or the manual steering command value and a second control mode in which the electric motor is controlled based on the integrated angle command value according to a lateral position of a vehicle with respect to a lane in a driving assist mode.

This motor control device comprises: a manual steering command value calculation unit that calculates a manual steering command value by using a torsion bar torque; an integrated angle command value calculation unit that calculates an integrated angle command value by adding a manual steering command value to an automatic steering command value for operation assistance; and a control unit that drives and controls an electric motor on the basis of the integrated angle command value. In an operation assistance mode, the manual steering command value calculation unit is configured to calculate the manual steering command value by using a motion equation of a steering device reference model. The manual steering command value calculation unit calculates the manual steering command value by using, as a virtual spring reaction force in the motion equation, a virtual spring reaction force obtained by adding a virtual spring reaction force according to the automatic steering command value to a virtual spring reaction force according to the manual steering command value.
