IBM Rational - Eaton/UPS Customer Reference Video
Ram Ramakrishnan: At Eaton, we know the world won't wait and we are moving forward to a sustainable future.
Joseph Wolfsberger: We believe that together we can have greater impact than the sum of our own individual efforts.
Ram Ramakrishnan: We take pride as engineers, we create things, we make things work, we make things better and we have a great opportunity working in sustainable products in green technologies… which is impacting how the world operates in the future.
Joseph Wolfsberger: Hydraulic Hybrid Powertrain is an incredibly exciting new technology.
We began this project as a partnership with EPA and with UPS to develop this technology around the Hybrid Powertrains.
Ram Ramakrishnan: We basically are running at efficiency levels, never seen before.
Joseph Wolfsberger: As you are approaching a stop sign, you put your brakes on; all that energy that’s normally lost is captured in a hydraulic system.
Ram Ramakrishnan: When the vehicle is ready to start again, instead of using the engine power to give it the initial propulsion; we release the energy from the tanks.
This process can recover and reuse more than 70% of the energy normally wasted during braking.
Joseph Wolfsberger: All the energy you would have lost by braking is now put back into the system and it allows you to accelerate.
Ram Ramakrishnan: There is no conventional transmission…which frees up the engine to be operated at its most efficient point, which we call its sweet spot.
Joe Wolfsberger: The Hydraulic Powertrains are very good right now for the trucks that do a lot of stop-and-go in the course of their normal operations.
Ram Ramakrishnan: That’s why the UPS package delivery vehicles lends itself, once again, very naturally and very nicely to our series hybrid platform.
Joseph Wolfsberger: EPA laboratories studies showed it to be about 60% to70% more efficient, and a 40% reduction in CO2 emissions over conventional vehicles.
Ram Ramakrishnan: The goal of Eaton’s hydraulic hybrid system is to minimize fuel consumption and emissions without adversely affecting the vehicle’s ability to do its job. IBM software is helping us optimize the system to meet those requirements.
Joseph Wolfsberger: The software parts of it are probably some of the most important aspects of this whole new technology.
Ram Ramakrishnan: The software, again, has got to understand the engine speed; it's got to understand the vehicle load, because it's a very complicated control logic.
We felt that the suite of tools from IBM, which is the Rational toolkit, was the right choice for us.
What we do is we model the different systems in a Rhapsody environment… and when we believe that we have a set of code logic that works; we actually push a button and convert that picture into a suitable software; what we call a Picture-to-code. Once it’s tested, it goes into the controller or the electronic layer which then gets installed in the vehicle.
Joseph Wolfsberger: It’s the right technology we need, the right software we need.
Ram Ramakrishnan: Having a software, which is very reliable, to ensure that the vehicle delivers not only on its mission, but also delivers the mission safely, that’s where the criticality in the software development comes in.
Joseph Wolfsberger: We really identified IBM as a critical business partner for us to ensure the success of this project. We really felt that in order to make this project a success, we needed to have them part of the team.
Ram Ramakrishnan: IBM’s values, goals, objectives not only just in the area of sustainability and green, but overall the company and values and ethics, it’s absolutely aligned with what we have within Eaton Corporation and it’s just a terrific partner.
Joseph Wolfsberger: We think that as this develops and becomes more widespread, it truly can have a very powerful impact on reducing the greenhouse gas emissions around the globe.
