Abstract
Depletion of fossil fuel sources has become a concern to humankind as it is one
of non-renewable energy that has been use over years. One of the alternative way to
overcome the problem is the development of hybrid vehicles. Hydraulic Hybrid Vehicle
(HHV) is one of the hybrid though it is uncommon compared to Hybrid Electric Vehicle
(HEV), however the hydraulic hybrid technology has found its way to emerge itself into
automotive industry. One of the configuration of hydraulic hybrid is parallel
architecture, in which a conventional vehicle can be retrofitted into this architecture.
The purpose of this project is to retrofit a conventional vehicle, Perodua Myvi 1.3L,
with a hydraulic hybrid system with minimal cost. This is achieved by modification of
the rear axle hub to placed hydraulic motor and pump on the rear axle of non-driven
wheels. Upon retrofitting, a simulation of fuel economy on MATLAB is used to
determine a suitable component sizing of hydraulic component and to determine the
fuel economy improvement of the system.
