1. A vehicle system, comprising:
- a engine capable of disabling and enabling at least one cylinder;
a motor coupled to said engine capable of absorbing torque and providing torque;
a controller for disabling and enabling said at least one cylinder, and during at least one of disabling and enabling, varying torque of said motor to compensate for transient changes in engine output torque caused by said one of disabling and enabling.

15. A vehicle system, comprising:
-
a engine capable of disabling and enabling at least one cylinder;
a motor coupled to said engine capable of absorbing torque and producing torque;
a controller for disabling and enabling said at least one cylinder, and during at least one of disabling and enabling, varying torque of said motor to compensate for transient changes in engine output torque caused by said one of disabling and enabling, and varying whether said motor produces or absorbs torque based on operating condition. - View Dependent Claims (16, 17, 18)

19. A computer storage medium having stored data representing instructions executable by a computer to control a vehicle system, the vehicle system comprising a engine capable of disabling and enabling at least one cylinder and a motor coupled to said engine capable of absorbing torque and producing torque, the medium comprising:
-
code for disabling and enabling said at least one cylinder;
code for, during at least one of disabling and enabling, varying torque of said motor to compensate for transient changes in engine output torque caused by said one of disabling and enabling; and
code for varying whether said motor produces or absorbs torque based on operating condition. - View Dependent Claims (20)
