This paper presents vehicle’s ride comfort performance evaluation after the conversion into an electric vehicle (EV) and the possible ride comfort improvement by an active suspension system have been investigated. The evaluations were done using a validated 7 degrees of freedom of vehicle’s ride model. The mathematical modelling of the vehicle’s ride as well as its validations was developed in order to predict the vehicle’s ride behaviours. The model was then integrated with the active suspension system in order to improve the EV conversion’s ride comfort performance. It was found that the modifications towards an EV conversion do not affect vehicle’s ride comfort performance significantly, except it changes only the vehicle’s vertical displacement, pitch rate and pitch angle responses. However, further application of an active suspension system in EV conversion was found to be able to improve all of the observed responses for ride comfort performance of an EV conversion by overall improvement of 71.1 percent.

This paper presents an evaluation of ride comfort performance of a passenger vehicle when converted into an electric vehicle (EV). The evaluations were done using a validated 7 degrees of freedom of vehicle’s ride model. The developed vehicle’s ride model was used to predict the vehicle’s ride behaviours when subjected to random road profiles. The ride model of EV conversion was then integrated with the active suspension system in order to further improve the EV conversion’s ride comfort performance. It was found that the modifications of a normal passenger vehicle into an EV conversion do not affect vehicle’s ride comfort performance significantly, except the conversion changes only the magnitude of vehicle’s vertical displacement, pitch rate and pitch angle responses. However, the integration of an active suspension system in EV conversions ride model was improves the observed responses of EV conversion’s ride comfort performance by overall improvement of 65.7 percents.
