Abstract:
A control apparatus for a hybrid vehicle including: an engine which outputs a propulsion force for a vehicle; an electric motor for assisting the output from said engine; a battery for an electric motor that drives said electric motor and also stores electric power generated by said electric motor; and a storage state monitoring device which monitors a stored charge of said electric motor battery,wherein one condition for permitting operation of vibration damping control by said electric motor, for suppressing vibration caused by torque variation of said engine, is that a stored charge of said electric motor battery detected by said battery storage state monitoring device must be greater than a predetermined stored charge threshold, and when said condition is satisfied, vibration damping is performed, or alternatively when said condition is not satisfied, vibration damping is inhibited.
