| Summary: | The first decade of the 21st century had seen a growing and increasing concern
on the lasting effects of human activities towards the environment. Issues such as global
warming as well as the dwindling reserves of non-renewable sources of energy have
forced the human race to look for the best replacement or alternative solutions, across
all fields of industries. In the automotive industry, various researches are being
conducted to produce sustainable transportation systems, which can be divided into the
development of renewable source of energy as well as the improvement of energy
efficiency. The improvement of energy efficiency has seen the growth of hybrid
vehicles, which is proven to reduce the consumption of fuel and emission of pollutant.
Regenerative braking is one of the systems applied in hybrid vehicles, where the energy
used during braking is recovered and stored for future use. This study evaluates a
Regenerative Motor-Pump System for the application of a Hydraulic Hybrid Vehicle
(HHV). The instrumentation and control for the system was developed, where the
design was tailored specifically for a truck. The Regenerative Motor Pump System was
found to be able to recover 40% of the braking energy, resulting in 60% less energy
required to move a HHV truck from stationary to 10 km/h, as compared to the total
dependence to Internal Combustion Engine (ICE). Additionally, HHV and
conventional vehicle simulation drivetrains were developed based on the experimental
data obtained and tested on two different drive cycle tests. Firstly, a stop-and-go drive
cycle show that the HHV truck was able to save up to 33% of energy compared to a
conventional truck. Moreover, a comparison between conventional and a HHV truck
using the New York Garbage Truck Cycle (NYGTC) shows a saving of energy up to
29.6%. The results obtained shows that there are significant benefits for the
implementation of hydraulic-based regenerative braking systems, especially for vehicles
with large mass undergoing multiple stop-and-go driving cycles. |
