Abstract:
Within the last decade, due to increasing fuel prices, unstable political situation in major oil producing nations and global warming, there is an increased demand for fuel efficient and environment friendly vehicles. In this context, research is being concentrated in the field of advanced, greener powertrain configurations ranging from hybrids to EVs to fuel cells to HCCI engines. The efficacy for any of the above stated powertrain technology, lies in the optimum component specification. Component specification, operational reliability, & life prediction are highly dependent on the traffic condition, driving nature and vary from country to country. For developing countries, like India, where the traffic & drive pattern are dense & slow moving, there is a dire need for generating load cycle based on Real World Usage Profile (RWUP). The paper will propose a systematic approach to create load cycles in order to derive component specifications for the powertrain based on RWUP. Load cycles refer to the load variation with respect to time for the component based on the vehicle operating condition. This paper will also discuss about the powertrain control algorithm for various vehicle operating conditions and also create multiple shift schedules for manual transmission. Based on Indian RWUP, shift schedule, vehicle load and powertrain control algorithm, a series of simulations will be run for generating the energy throughput for the specific powertrain components. This energy throughput will be further synthesized for generating the load cycle of the components.
