The legislations on emission reduction is getting stringent everywhere in the world. India is following the same trend, with Government of India (GOI) declaring the nationwide implementation of BS 6 legislation by April 2020 and Real Driving Emission (RDE) Cycle relevant legislation by 2023. Additionally GOI is focusing on reduction of CO2 emissions by introduction of stringent fleet CO2 targets through CAFE regulation, making it mandatory for vehicle manufacturers to simultaneously work on gaseous emissions and CO2 emissions. Simultaneous NOx emission reduction and CO2 reduction measures are divergent in nature, but with a 48 V Diesel hybrid, this goal can be achieved.
The study presented here involves arriving at the right future hybrid-powertrain layout for a Sports Utility Vehicle (SUV) in the Indian scenario to meet the future BS 6 and CAFÉ legislations. Diesel engines dominate the current LCV and SUV segments in India and the same trend can be expected to continue in future. An existing SUV from the Indian market has been selected as a target base vehicle for this study. The base SUV vehicle meets the BS 6 legislative requirements with MIDC cycle. The focus is on 48 V P0 and P2 hybrid layout evaluation and optimization through simulation techniques using Matlab/Simulink models.
This RDE cycle (Pune RDE), has been developed out of actual vehicle measurement in and around Pune city, capturing real transient vehicle behavior and start-stop / energy recuperation potential availability. The study also includes the effect of these hybridized powertrain architecture on the reduction/optimization of the needed Exhaust After Treatment System (EATS) size as well as fluid consumption, due to reduced engine out NOx emission. Existing vehicle platform is on a 12 V system and migration to a 48 V system will call for additional system and development cost.
