Vehicle suspension system plays important role in maintaining constant contact of the wheels with the ground, as well as isolating the occupants from vibrations from uneven road surfaces such as bumps, humps and potholes. The most common suspension system in passenger vehicle today is the passive type suspension which operating without providing any external energy to the system, hence it is called passive. The research advancement leads to the invention of semi-active and active suspension which requires external source for control. The objective of this paper is to evaluate the performance of passive and semi-active vehicle suspension system with various control strategy and recommend a modified control strategy for vehicle semi-active suspension system. The vehicle quarter model was used for suspension mathematical modelling and the suspension system performance of sprung mass acceleration and un-sprung mass displacement were simulated by considering various semi-active control strategy. Three control strategies of Sky-hook, Ground-hook and Modified sky-hook control were applied to the simulation. For Sky-hook and Ground-hook, the gain variable was varied by considering the values of 1000, 3000 and 5000. For modified Sky-hook model, the gain of 3000 were considered by changing the control variable values to 0, 0.25, 0.5, 0.75 and 1. The findings suggest that the semi-active suspension outperforms a passive suspension system. The Sky-hook control strategy was more desirable towards increasing comfort at the sacrifice of handling performance, whereas the Ground-hook control strategy increases the handling performance at the sacrifice of comfort. The modified skyhook control strategy combines both of the control logics into one and the gain value of 0.5 was found to produce the best results both in increasing the comfort and the suspension handling performance.
