Abstract
PURPOSE:To make inexpensive and advanced control performable by compensating a fundamental requisition air quantity according to a signal out of a detecting device detecting an engine driving state, comparing it with a detected value out of an intake air quantity sensor, and controlling a bypass flow rate according to this result. CONSTITUTION:A fundamental requisition air quantity Q1 predetermined to throttle opening and engine speed is found out of each output signal of a throttle opening sensor 14 and engine speed sensor 15, a correction value Q'1 of the requisition air quantity is operated by output signals out of a sensor group detecting engine driving conditions, for example, an intake air temperature sensor 16, an atmospheric pressure sensor 17 or the like, comparing it with a signal Q2 out of an intake air quantity sensor 18. When Q'1<Q2 is the case, a driving current to a control valve 12 is made to go up as much as the fundamental unit. The control valve 12 has an input port 10 and an output port 9 interconnected to each other, and since an opening area of a bypass valve 5 is increased, a relief quantity is increased and supercharging pressure is decreased instead.
