Multi-disciplinary teams from three global software-engineering facilities model the system’s physics and graphically create control algorithms to embed into a microprocessor.
Having two gear ratios rather than the single ratio that is typical of EVs enables the eAxle to boost the i8's all-wheel-drive performance across its entire speed range.
Using CAE simulation tools early and often, hardware prototyping is slashed and complexity contained while developing the next generation of powertrains.
General Motors announced on October 20 that it is partnering with Korean electronics giant LG Corp. in development of the 2017 Chevrolet Bolt EV’s entire powertrain and other vehicle subsystems, in a new business relationship that GM engineering executives said could point to a new model for electrified vehicle development.
GM recently announced that its fuel-cell engineering team is working with the U.S. Army TARDEC to develop a prototype pickup truck with a commercial hydrogen fuel-cell powertrain that is capable of meeting U.S. military duty cycles. The vehicle will be put into daily use and driven by soldiers for 12 months.
