PROBLEM TO BE SOLVED: To provide an inexpensive torque fluctuation suppressing device for an engine with high maintainability and reliability. SOLUTION: A reference signal for suppressing torque fluctuation of the engine 1 is produced based on an engine revolution pulse signal Ne, and a torque fluctuation suppressing signal Tc of the engine 1 is produced by changing phase characteristics and amplitude characteristics of the reference signal by alternating current component vac of a vehicular speed pulse signal Vsp to drive a motor generator 2 according to the torque fluctuation suppressing signal Tc. Since torque fluctuation suppressing control is performed using a vehicular speed sensor and an engine revolution sensor used for a vehicular speed meter and vehicular speed control without providing a torque sensor, an expensive torque sensor is not required, and the device becomes inexpensive, and the maintainability and the reliability can be improved. |
