Abstract. Vehicle semi-active suspension has been more and more widely used since it can provide good operation stability and ride comfort. This paper focuses on embedded system design based on Infineon C164CI microcontroller for vehicle semi-active suspension. The hardware design of electronic suspension control unit (ESCU) is introduced in detail. The integrated control strategy for semi-active suspension system is proposed. The test bench of hardware-in-the-loop simulation (HILS) is built and the functions of ESCU are verified. The HILS simulation results show that the performances of ESCU achieve design requirement and the integrated control strategy is rational and effective.

“…The Series Active Variable Geometry Suspension (SAVGS) presented in this paper [8], [9], which is a new implementation of the variable geometry active suspension concept [10], [11], aspires to fill the gap between current semi-active and active solutions, offering superior performance than the former while avoiding the main disadvantages of the latter. When compared to other variable geometry alternatives, such as the Delft Active Suspension (DAS) [12] and subsequent developments [13], [14], the SAVGS offers advantages such as an inherent fail-safe behavior and negligible unsprung mass increment.…”

Abstract-A new family of electro-mechanical active suspensions that offers significant advantages with respect to passive and semi-active suspensions, while at the same time avoiding the main disadvantages of alternative active solutions, is presented in this paper. The Series Active Variable Geometry Suspension takes a conventional independent passive or semi-active suspension as its starting point, and improves its behavior by actively controlling the suspension geometry with an electro-mechanical actuator. The advantages of this type of suspension are discussed and its simplest variant is studied in detail. Insight on the design process, as well as on the actuator modeling and selection is provided. Moreover, a control system for pitch attitude control of the chassis is presented. Simulation results obtained with a high-fidelity, fullvehicle, non-linear model of a high performance sports car that includes actuator dynamics and saturation limits are shown to confirm the potential of the proposed system.

“…In conventional suspension systems, composed of springs and dampers or shock absorbers, the characteristics of the suspension elements cannot be changed and, hence, conflicting trade-offs between different performance indices, such as ride comfort and road holding, are extremely difficult to be achieved (Sharp and Hassan, 1986). As a consequence, these passive suspensions are only effective in a limited range of the vehicle operation.…”
