Vehicles equipped with internal combustion engines (ICE) are major contributors to greenhouse gas (GHG) emissions and dependence on fossil fuels. Alternatives such as electric, hydrogen fuel cell biofuel-based propulsions being considered a replacement for the well-established ICE vehicles reduce GHG provide sustainable transportation. This paper will compare various heavy-duty vehicle (HDV) pr...

In modern heavy duty trucks the battery is a central component. Its traditional role as an energy source for engine cranking has been extended to include powering a number of electrical components on the truck, both during driving and during standstill. As a consequence of this it is important to know how much a battery in use has aged and lost in terms of capacity and power output. The difficu...

In this paper we extend previous control design applied to an electropneumatic clutch actuator. A dual-mode switched nonlinear controller design and an adaptive nonlinear observer design are combined to achieve position control of the clutch actuator with only position measurements available. The observer provides estimates of position, velocity, chamber pressures, friction state and parameters...

Makers of heavy-duty diesel engines (HDDEs) need to reduce their inventory of old-generation products in preparation for the demand for next-generation products that satisfy new emission regulations. In this paper, a new demand forecasting model is proposed to reflect special conditions raised by the technological generational shift owing to new emission regulation enforcement. In addition, sen...
