This paper proposes a current limits distribution control strategy for a parallel hybrid electric vehicle (parallel HEV) which includes an advanced powertrain concept with two electrical driving axles. One of the difficulties of an HEV powertrain with two electrical driving axles is the ability to distribute the electrical current of one high voltage battery appropriately to the two independent electrical motors. Depending on the vehicle driving condition (i.e., car maneuver) or the maximization of the entire efficiency chain of the system, a suitable control strategy is necessary. We propose an input-output feedback linearization strategy to cope with the nonlinear system subject to input constraints. This approach needs an external, state dependent saturation element, which translates the state dependent control input saturation to the new feedback linearizing input and therefore preserves the properties of the differential geometric framework.

Motor Trend Magazine�s selection of the Chevrolet Volt as its 2011 Car-Of-The-Year saw the publication inundated with responses, the vast majority of these polarized between astute praise and bewildering condemnation. Here, I will read you some of our best Volt Car-Of-The-Year reader mail. And along the way, offer a few of my own responses � including thoughts on how the gulf between these contentious camps of enthusiasts might eventually be bridged.

The Idaho National Laboratory is collecting data from grid-connected electric drive vehicles and charging infrastructure that have been deployed across the United States in five large-scale demonstrations funded by the U.S. Department of Energy. These demonstrations include The EV Project infrastructure demonstration, led by ECOtality North America; Coulomb Technologies� ChargePoint America infrastructure demonstration; General Motors� Chevrolet Volt extended range electric vehicle demonstration; Chrysler�s Ram plug-in hybrid electric vehicle demonstration; and the Ford Escape plug-in hybrid electric vehicle advanced research fleet demonstration. This presentation describes real-world vehicle and charging infrastructure usage observed during the early stages of these demonstrations. Presenter John Smart, Idaho National Lab.

The Pennsylvania State University is one of 16 North American universities that participated in the EcoCAR advanced vehicle technology competition (http://www.ecocarchallenge.org/). A series-hybrid-electric vehicle based on a General Motors crossover SUV platform has been designed, built and tested for this purpose. The powertrain features a 1.3 L turbodiesel engine running on a B20 fuel system, a 75kW generator directly coupled to the engine and advanced lithium-ion batteries. In this paper, the vehicle architecture and control strategy are detailed and performance predictions (e.g., acceleration, fuel consumption and emissions) are presented. This includes discussion of the development process that led to the selected designs. The predicted performance is compared with data obtained on a chassis dynamometer and during on-road measurements over specified drive cycles. Presenter Shawn Getty
