Abstract
Conditions for permitting operation of vibration control are that; a stored charge of a battery 17 for an electric motor detected by storage state monitoring devices 15 and 24 is larger than a predetermined storage charge threshold, a vehicle's engine is idling, engine speed is within a prescribed range, and engine load is within a prescribed range. When all these conditions are satisfied, vibration damping control by a vibration damping control device is performed.
Claims11
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.
A control apparatus for a hybrid vehicle, wherein conditions for permitting operation of vibration damping control require that, in addition to a stored charge of said electric motor battery detected by said storage state monitoring device being greater than a predetermined stored charge threshold, the vehicle is idling, engine speed is within a prescribed range, and engine load is within a prescribed range, and vibration damping control is performed when all conditions are satisfied.
