<p><P>PROBLEM TO BE SOLVED: To provide a supercharger control device structured to suppress high frequency noise generated from an exhaust gas turbine type supercharger by applying measures to the exhaust gas turbine type supercharger itself. <P>SOLUTION: The supercharger control device 1 is provided with a variable exhaust turbine type supercharger 4 mounted for an engine 2, a noise sensor 8 for detecting sound generated from this variable exhaust turbine type supercharger 4 and an ECU 3 for controlling the variable exhaust turbine type supercharger 4 based on a signal from the noise sensor 8. The ECU 3 conducts control to lower a turbine rotation speed of the variable exhaust turbine type supercharger 4 when the signal from the noise sensor 8 reaches a predetermined value. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
