Filed: 2003-01-24
Abstract: <P>PROBLEM TO BE SOLVED: To prevent torque difference generated by increase in rotational speed of an electric motor exceeding a target value between the time when a closing instruction is input to a bypass valve and the time when closing operation of the valve is completed.  <P>SOLUTION: A control device comprises: a turbocharger 3; an electric supercharger 4 disposed downstream of the turbocharger 3; a bypass passage 10 bypassing the electric supercharger 4 and connecting upstream of the electric supercharger 4 with downstream of the electric supercharger 4; a bypass valve opening/closing the bypass passage 10; and a means 16 detecting acceleration requirement of a vehicle. The control device associates the electric supercharger 4 with the bypass valve 6 to control them, when the acceleration requirement is detected. The control device further comprises a control means. The control means sets, as a target rotational speed, a rotational speed where an air amount flowing in the intake passage 12 downstream of the electric motor 4b is not larger than an air amount of upstream, calculates a predicted rotational speed after operation time of the opening/closing valve 6 based on a rotational number of the electric motor 4b at present time, and outputs closing instruction to the bypass valve 6 when the predicted rotational speed reaches the target rotational speed.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
