Modelling and ride analysis of a hydraulic interconnected suspension based on the hydraulic energy regenerative shock absorbers

•A novel design of a HIS-HESA based on a 7-DOF full vehicle model was presented.•Different HIS-HESA working modes including bounce, pitch and roll modes were investigated.•HIS-HESA can harvest a maximum power of 397 W at 72 km/h and class C ISO-road.•The ride comfort and road holding using the HIS-HESA were improved by 33% and 20%.•Controlling the external resistance can realize the trade-off between ride comfort and energy recovery.
