Riding comfort and ground holding are the key parameters in the performance of vehicle suspension systems. The acceleration of sprung mass as well as ground forces transmitted will influence the ride comfort to a greater extent. The firm contact established between the tire and the road is termed road holding, which influences the vehicle’s directional stability. Recent technological advancements have led to electronically controlled suspension systems with different control strategies. The Semi-Active Suspension System (SASS) has been proven to be a trade-off solution between passive and active suspension systems. It can continuously vary the damping without consuming excessive power, unlike active suspensions. The different control algorithms developed in SASS achieved improved riding comfort and ground holding at the same instant. The commercial development of a magnetorheological (MR) damper makes the SASS to be more reliable. Different controllers like fuzzy and skyhook controls have been developed over the years. This research article summarizes the research work in control systems used for semi-active suspensions over the pre and post-COVID-19 period. The recent advancements in mathematical modeling, simulation, and experimental testing have been discussed in detail.

摘要

Riding comfort and ground holding are the key parameters in the performance of vehicle suspension systems. The acceleration of sprung mass as well as ground forces transmitted will influence the ride comfort to a greater extent. The firm contact established between the tire and the road is termed road holding, which influences the vehicle’s directional stability. Recent technological advancements have led to electronically controlled suspension systems with different control strategies. The Semi-Active Suspension System (SASS) has been proven to be a trade-off solution between passive and active suspension systems. It can continuously vary the damping without consuming excessive power, unlike active suspensions. The different control algorithms developed in SASS achieved improved riding comfort and ground holding at the same instant. The commercial development of a magnetorheological (MR) damper makes the SASS to be more reliable. Different controllers like fuzzy and skyhook controls have been developed over the years. This research article summarizes the research work in control systems used for semi-active suspensions over the pre and post-COVID-19 period. The recent advancements in mathematical modeling, simulation, and experimental testing have been discussed in detail.
