<P>PROBLEM TO BE SOLVED: To prevent deterioration of operation feeling by preventing occurrence of the so-called stepped feeling when temperature rises during operation restriction by a temperature switch for protecting a motor and an electric circuit in an electric assist supercharger. <P>SOLUTION: This circuit includes a motor applying torque to a compressor compressing air sucked from an exhaust manifold, a motor driver controlling operation of the motor, and a temperature sensor measuring temperature of the motor and the motor driver. The motor driver control motor output to an upper limit or lower in response to temperature increase of the motor and the motor driver according to a relation between temperature of the motor and the motor driver, and the upper limit of motor output stored as preset maps 3, 5, 6. <P>COPYRIGHT: (C)2011,JPO&INPIT |
