Title: Control method of rotation in operation stop of internal combustion engine, control device of rotaion in operation stop of internal combustion engine, and storage medium
Inventor: MORIYA TAKANORI
IPC: F02D29/02
Filed: 2002-08-27
Abstract: <P>PROBLEM TO BE SOLVED: To suppress vibration when stopping the rotation of an internal combustion engine by the rotating drive torque from another drive source in the operation stopping state of the internal combustion engine.  <P>SOLUTION: The positive rotating drive torque of a motor generator is intermittently increased by setting an offset instruction current value Toft (S460), whereby the increase in engine friction is canceled by the output of the motor generation to suppress the rotating pulsation. Since the resonance is minimized, therefore, the vibration can be suppressed when stopping the rotation of the engine. Further, since the reduction in engine speed is moderated by regularly outputting the positive rotating drive torque from the motor generator (S454 and S456), the rotating speed change in deceleration starting or rotation stopping is minimized, and the vibration can be further effectively suppressed.  <P>COPYRIGHT: (C)2004,JPO
