Architecture of a Hydraulic Hybrid Vehicle with Pressure Cross-Feedback Control
A hydraulic hybrid vehicle equipped with the hydraulic transformer is proposed.The hybrid system features in rotary swash plate type hydraulic transformer and pressure cross-feedback control.The full numerical model has been built.Extensive simulated and tested results are given.The contributions of the hydraulic transformer dynamics to the hydraulic hybrid vehicle performance are investigated.The proposed hydraulic hybrid vehicle can achieve the ideal vehicle dynamic performance by adjusting the hydraulic transformer controlled angle.The switching between the driving and the regenerative breaking of the hydraulic hybrid vehicle is realized by the pressure cross-feedback control.The propulsion mode of the hydraulic hybrid vehicle can be changed automatically.The larger hydraulic transformer controlled angle realises a higher driving pressure while the smaller one achieves a higher driving flow.Due to the small inertia of the hydraulic transformer,the hybrid system is able to satisfy the speed requirement of the driver.
