This paper researches on embedded system design based on MC9s12Dp256 microcontroller for vehicle semi-active suspension. The hardware design of suspension control unit (SCU) is introduced. The integrated control strategy which integrates Skyhook and MiniMax strategies is proposed. The hardware-in-the-loop simulation (HILS) test on a two-degree-of-freedom quarter car semi-active suspension system model is carried out. The functions of SUC are verified and the performance of passive suspension and semi-active suspension is compared. The simulation results indicate that the performance of SCU achieves design requirement. In comparison with passive system, the control effect of integrated control strategy can be improved in ride comfort and drive safety.

Active camber angle position systems for vehicle wheel alignments can better regulate the wheel camber angle position in different operating conditions of vehicles. The aim of this work is to illustrate the application of active camber angle position theory. A prototype of one wheel equipped by the double wishbone suspension system and the variable camber angle control with suspension system concept is proposed. Active camber system uses a linear actuator with Arduino microcontroller. A comparative study was done on wheel vibration characteristics of the conventional camber system (passive system) and active system. The experimental results and analysis show that the vibration signature is influenced by the camber angle position. It is found that the vibration signal increases when the vehicle wheel speed and normal load are increased. Moreover, the results indicate that the root mean square (RMS) of vehicle wheel vibration is improved by 17.78%, 38.6% and 49.63% at wheel speed of 250 rpm, 500 rpm and 750 rpm respectively by using the proposed active camber angle. The vehicle wheel vibration behaviour with active camber angles is likely to be optimum under the different wheel operating conditions.

The objective of this paper is to design an efficient control scheme for car suspension system. The purpose of suspension system in vehicles is to get more comfortable riding and good handling with road vibrations. A nonlinear hydraulic actuator is connected to passive suspension system in parallel with damper. The Particles Swarm Optimization is used to tune a PID controller for active suspension system. The designed controller is applied for quarter car suspension system and result is compared with passive suspension system model and input road profile. Simulation results show good performance for the designed controller.

The paper deals with buckling and strength analysis of suspension system rods made of carbon fibre reinforced polymer (CFRP) laminate. The whole suspension system of urban solar vehicle, Eagle Two, designed by Lodz University of Technology students was considered. The calculations and analysis focused on suspension rods, where the traditional metal material was replaced with CFRP laminate. The influence of layer arrangement on rod strength, static, and dynamic buckling were analysed. The research was conducted using numerical simulations employing finite element method software. The static and dynamic load was considered. The obtained results show that the plies’ order in the laminate influences both the strength and stiffness of the considered rod. The best results considering both failure force and longitudinal elasticity modulus were obtained for the stacking sequences with axially oriented (0°) plies on the outside of the rod.
