HBMC stands for Hydraulic Body Motion Control. The HBMC system consists of accumulators on the chassis and hydraulic struts within the suspension.
Each shock absorber's inner and outer sleeves are connected to an accumulator. The vehicle's left inner sleeve and right outer sleeve are connected to one accumulator, while the left outer sleeve and right inner sleeve are connected to another accumulator. The accumulators implement various control measures for body posture based on the vehicle's different driving conditions.
