Title:
CONTROL DEVICE FOR FLOW CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/2021/006036
Kind Code:
A1
Abstract:
A control device (40) for a flow control valve (12) comprises a target opening degree setting unit (50), an opening degree control unit (60), and a control parameter changing unit (70). The target opening degree setting unit sets a target opening degree of the flow control valve. The opening degree control unit controls an actual opening degree of the flow control valve to match the target opening degree. The control parameter changing unit changes a control parameter for controlling the operation of the flow control valve. The target opening degree setting unit sets a target wall temperature in accordance with a load state of an internal combustion engine. When the absolute value of a difference between an actual wall temperature and the target wall temperature is larger than a prescribed value, the control parameter changing unit changes the control parameter such that a response speed of the actual wall temperature is faster than when the absolute value of the difference is not larger than the prescribed value.
