Hydraulic control valve integrated novel semi active roll resistant interconnected suspension with vertical and roll coordinated control scheme

Abstract

Though the interconnected active suspension enhances the performances of roll dynamics along with the primary functions of passive suspension, it requires an external pressurized fluid supply. Also, higher energy is required to attain the variable damping force in an active interconnected system. Therefore, this research attempts to control the vehicle roll without an external fluid supply by novel semi-active based roll-resistant interconnected suspension system (SARR-HIS). The variable damping is achieved by utilizing the pressure developed in the chambers and hydraulic control valve (HCV), while the suspension compresses. The amount of the flow passes through the HCV is controlled by a model predictive controller. In addition, GA based optimization were performed to identify the optimal passive roll-resistant hydraulic interconnected suspension (PRR-HIS) parameters. For the controller design, vehicle plant model is estimated by the simple identification method in Matlab environment. On the AMESim platform, vehicle with SARR-HIS system integrated model was built and controlled in a co-simulation environment. To assess the effectiveness of the proposed suspension and its control strategy, the anti-roll bar (ARB) integrated passive standalone suspension, optimized PRR-HIS, and proposed SARR-HIS systems are tested under C class road roughness without steer and double lane change maneuver.

Standalone and Interconnected Analysis of an Independent Accumulator Pressure Compressibility Hydro-Pneumatic Suspension for the Four-Axle Heavy Truck

“…Therefore, the anti-roll bar is not used in this study. The standalone HIS, HPIS, and proposed-HPIS depict the passive or separate, hydraulically interconnected suspension, hydro-pneumatic interconnected suspension, and proposed hydro-pneumatic interconnected suspension, respectively [55]. The sinusoidal signal as expressed in Equation ( 60) is given as an input to the vehicle wheels with various phase shifts.…”

Topology Optimization Design and Dynamic Performance Analysis of Inerter-Spring-Damper Suspension Based on Power-Driven-Damper Control Strategy

“…While the use of inerters can passively improve the dynamic properties of vehicles, semi-active suspension systems were developed to provide a more balanced compromise between cost and performance. In a semi-active suspension system, the damping force can be adjusted based on operating conditions to improve suspension performance [17][18][19]. Karnopp and Crosby first proposed the concept of semi-active suspension.…”

Coordinated Control of ESP-SAS System Considering Roll

“…Finally, the simulation results show that the proposed control strategy can improve the stability and safety of a four-wheel independent drive electric vehicle. A distributed cooperative control structure, as References [18][19][20][21] proposed, adjusts the roll dynamics by controlling the damping force of the semiactive suspension and suppresses the overshoot and oscillation of yaw rate and lateral velocity. References [22][23][24] designed a coordination strategy based on fuzzy logic to coordinate each subcontrol, including active steering, active braking, and active roll control systems.…”
