Hybrid vehicle, equipped power source not only gas engine but also motor, power electronics and differing types of transmissions, manifests more complicated/specific/exceptional NVH behaviors than that of gas powered vehicle, like parking engine start/stop for charging, EV mode traction/recuperation, mode switch, etc. On top of that, differing hybrid architecture exists, depending on number and location of motor and type of transmission, hence NVH features and related control strategies are highly likely to be different even under identical driving scenarios, as such, the holistic and deep insight into the NVH features and related control strategies are very meaningful for hybrid vehicle NVH performance refinement, and will expedite the process of vehicle NVH development.
