Technology assessment becomes easier with a validated vehicle model!
“The real challenge is not engines or engine technology as that’s already available, but system integration and optimizing them as per Indian driving cycle and the time required for calibration and validation” says Sandeep Sinha, chief operating officer at Cummins India.
A critical part of the design cycle is testing designs and performing iterations, allowing for improvements to be made to the design. But more challenging is the quality and quantity of resources and time required to build the requisites. India’s strive to comply within the emission norms simultaneously aiming for automotive electrification by 2030 can be readily seen from various efforts put by R&D. For achieving Bharat Stage VI norms, number of changes are to be done in engine systems to fit in the constraints. To achieve a reduction by 82% in Particulate Matter (PM) and by 68% in Oxides of Nitrogen (NOx), fast yet accurate simulations are needed to have a deeper understanding of the system. A company like Mahindra and Mahindra who is into various segments like trucks, SUVs, pick-ups and electric vehicles, maintaining a balance between several simulations for each vehicle category and then testing to satisfy the requisites is a big challenge. Ranges can be estimated, but, the fuel economy and emissions impacts will vary depending on the drive cycle for which a vehicle model is necessary.
“Spend your time designing your products, not gathering data and correlating vehicle models” is best suited for ‘PowertrainLive’. Computational Science Experts Group’s PowertrainLive is a high-fidelity, fuel economy prediction software that evaluates the vehicle-level impacts of technologies and components on fuel economy and system performance. The inbuilt vehicle models are validated with test data to obtain correct powertrain analysis. With software’s library of populated models, quantifying benefits on real production vehicles and over a wide variety of drive cycles is time and cost effective. Even with narrow breadth of data, the software can help you in calculating exact impacts on a specific vehicle instead of a rough calculation on single set of operating conditions for both, Conventional and xEV.
The main struggle in xEV is to overcome range and charging issues. PowertrainLive serves a wide range of electric vehicles like Nissan leaf, Toyota Prius, Chevy-Volt etc. which correlate well with a varied range of drive cycles such as UDDS hot start, UDDS cold start, HWFET, and US06. These models are readily assessable to study technology impact using Modified Indian Driving Cycle (MIDC). Any inbuilt Indian vehicle model, manual transmission / autonomous is also available to quantify fuel economy impact for real world driving conditions. The software also helps in quantifying impact of different oil grades for real world driving conditions.
CSEG has developed various Case Studies using PowertrainLive and the results obtained are encouraging. Software’s customization has always supported its customer with various custom module development including “HVAC module”, “Waste Recovery module” and “Hybrid Controller module” to study fuel economy impact.
With an aim to achieve automotive transformation, PowertrainLive has stepped into the Indian market with Contenance Technology Solution being its distributor in India. “We assure that our contribution towards Indian Automotive will benefit the OEMs and Tier 1 suppliers in the best way possible” Hemant Khalane, Technical Director, Contenance Technology Solution.
