Japanese Patent JP7466428

B2

To provide a limit value setting device which can properly set a cutting limit value.SOLUTION: A limit value setting device 1 for setting a current limit value for limiting a current flowing in a motor M of a valve-opening/closing timing control device 100 having a drive-side rotating body which synchronously rotates with respect to a crankshaft of an internal combustion engine mounted to a vehicle, a driven-side rotating body arranged coaxial with a rotation axial core of the drive-side rotating body, and rotating integrally with a camshaft of the internal combustion engine, a phase setting mechanism for setting relative rotation phases of the drive-side rotating body and the driven-side rotating body, and a motor M for driving the phase setting mechanism comprises: a voltage value information acquisition part 71 for acquiring voltage value information indicating a voltage value of an output voltage of a battery B which supplies power to the motor M; a voltage lowering information acquisition part 72 for acquiring voltage lowering information indicating the voltage lowering of the battery B when the power is supplied to the motor M; and a limit value setting part 73 for setting the current limit value for limiting the current flowing in the motor M from the battery B according to the voltage lowering.SELECTED DRAWING: Figure 2
