Recently, there are many research and development about xEV in automotive market. There are various types of xEV vehicles(EV/HEV/PHEV/mHEV) and each has its own characteristics. For example, EVs and HEVs differ greatly in weight distribution. HEV's engine room is heavier than EVs’ and EV's weight is evenly distributed due to the battery. It causes the pitch inertia moment difference between the two vehicle. This difference must be taken into account when converting pitch and bounce motion to independent vectors using a modal coordinate system to eliminate mutual effect. In addition, various matters to be considered for accurate conversion are described in this paper. The control logic performance was verified using an actual electric vehicle. |
