Title:
CONTROL DEVICE OF WASTE GATE VALVE
Document Type and Number:
Japanese Patent JP2019074017
Kind Code:
A
Abstract:
To provide a control device of a waste gate valve which can eliminate an adhesion state of the waste gate valve in an early stage.SOLUTION: An ECU controls a waste gate valve so as to be closed up to an opening by which prescribed target intake pressure can be obtained at a start of an engine (step S3). When an intake pressure difference between target intake pressure and actual intake pressure is not smaller than a prescribed intake pressure difference after the waste gate valve is controlled so as to be closed up to the opening by which the target intake pressure can be obtained (YES in step S4), the ECU controls the waste gate valve to a valve-opening side once, and after that, controls the waste gate valve so as to reach the opening by which the target intake pressure can be obtained once again (step S5). It is preferable that the ECU close the waste gate valve up to the opening by which the target intake pressure can be obtained after repeating the opening and closing of the waste gate valve a plurality of times at prescribed intervals.SELECTED DRAWING: Figure 2
