Abstract:
A valve control device includes a valve unit disposed in a cooling water circuit, and a control part which controls operation of the valve unit. The control part has a rotation angle instruction part, a duty ratio calculator and a determiner. The rotation angle instruction part calculates an instruction value of a rotation angle in response to an operational status of an internal-combustion engine. The duty ratio calculator calculates a duty ratio representing a ratio of ON period to OFF period regarding a voltage applied to an electric motor based on a difference between a detection value of the rotation angle detected by a detector and the instruction value of the rotation angle, and regulates the duty ratio to be lower than or equal to a predetermined upper limit. The determiner determines whether the duty ratio continues to be the upper limit during a predetermined period.

Claim (Index 1):
A valve control device for a cooling water circuit through which cooling water of an internal-combustion engine circulates also to other apparatus other than the internal-combustion engine and a radiator, the valve control device comprising:\n a valve unit disposed in the cooling water circuit to increase or decrease a flow rate of cooling water to the internal-combustion engine and to start or stop circulation of cooling water to the other apparatus; and a control part which controls operation of the valve unit, wherein the valve unit has an electric motor controlled by the control part in an application of a voltage to increase or decrease an output, a driven component having a rotor rotated by the output of the electric motor, the rotor rotating to increase or decrease the flow rate of cooling water to the internal-combustion engine and to start or stop the circulation of cooling water to the other apparatus, and\n a detector which detects a rotation angle of the rotor, \n the control part has a rotation angle instruction part which calculates an instruction value of the rotation angle in response to an operational status of the internal-combustion engine, a duty ratio calculator which calculates a duty ratio representing a ratio of ON period to OFF period regarding the voltage applied to the electric motor based on a difference between a detection value of the rotation angle detected by the detector and the instruction value of the rotation angle, the duty ratio calculator regulating the duty ratio to be lower than or equal to a predetermined upper limit, and a determiner which determines whether the duty ratio continues to be the upper limit during a predetermined period.
