摘要： In some embodiments of the present disclosure, an electric motor is used to generate correction torques to counteract unwanted torque pulses generated by an internal combustion engine during a cylinder deactivation mode. In some embodiments, the electric motor may be mounted to an accessory drive such as a power take-off mechanism or a front end accessory drive (FEAD). In some embodiments, the correction torques may be determined using an engine model. The correction torques help to reduce or eliminate noise, vibration, and/or harshness (NVH) during the cylinder deactivation mode.
