“…To satisfy these requirements, the Integrated Powertrain Control (IPC) approach, which is introduced in [17], is followed. It is a model-based control design philosophy for combined engine-aftertreatment-energy recovery systems that: -minimizes fuel consumption, while meeting emission constraints; -offers a robust emission control solution for both test cycles and real-life operation; -deals with complex system interactions; -uses models and optimal control theory to derive optimal control strategies; -relaxes the calibration complexity.…”

-Rankine-cycle Waste Heat Recovery (WHR) systems are promising solutions to reduce fuel consumption for trucks. Due to coupling between engine and WHR system, control of these complex systems is challenging. This study presents an integrated energy and emission management strategy for an Euro-VI Diesel engine with WHR system. This Integrated Powertrain Control (IPC) strategy optimizes the CO 2 -NO x trade-off by minimizing online the operational costs associated with fuel and AdBlue consumption. Contrary to other control studies, the proposed control strategy optimizes overall engine-aftertreatment-WHR system performance and deals with emission constraints. From simulations, the potential of this IPC strategy is demonstrated over a World Harmonized Transient Cycle (WHTC) using a highfidelity simulation model. These results are compared with a state-of-the-art baseline engine control strategy. By applying the IPC strategy, an additional 2.6% CO 2 reduction is achieved compare to the baseline strategy, while meeting the tailpipe NO x emission limit. In addition, the proposed low-level WHR controller is shown to deal with the cold start challenges.

“…Recently, issues related to global warming have been on the rise, primarily due to an increase in greenhouse gas emissions, including carbon dioxide, and the depletion of fossil fuels. In response to these environmental concerns, research focused on reducing exhaust gas emissions and decreasing dependency on fossil fuels has been actively pursued [20][21][22]. Such research is particularly important for increasing energy efficiency in agriculture [23][24][25][26], which has recently seen a shift from internal combustion engines to electric drive systems [27,28].…”

The advancement of agriculture and a shortage of labor have led to an increased use of agricultural machinery. However, the resulting environmental issues have prompted a shift from internal combustion engines to electric drivetrains. The electric drivetrain includes the installation of batteries, which can lead to decreased energy efficiency and significant loads on the vehicle due to their heavy weight. Consequently, the importance of ensuring the safety of agricultural machinery is being increasingly emphasized. The load on the frame of agricultural machinery is not consistent during off-road driving, and the accumulation of load cycles can lead to the destruction and failure of components. Therefore, it is necessary to ensure a level of safety and to predict the fatigue life. In this study, we estimate the safety factor and predict the fatigue life of weak points in an electrically driven, multi-purpose cultivation tractor based on working conditions (width, soil, and drive). Strain gauges were attached to these weak points to measure the strain, which was then converted to von Mises stress. Fatigue life was predicted using the rainflow counting method and the Palmgren–Miner rule. The results showed that the safety factor measured under various working conditions was greater than 1. The estimated minimum fatigue life was 124,176 years. Considering that the cultivator is used for 29.7 h annually and has a durability lifespan of 5 years, it is expected to be safely usable throughout its service life.

“…Well documented models for conventional and hybrid heavy duty vehicles exist. Some models of hybrid vehicles with aftertreatment systems also exist, like (Willems and Foster, 2009), however, to the authors knowledge no work where the interplay between exhaust system and hybrid vehicle, where the engine can be shut of, is studied and modeled can be found. Therefore we here aim to fill this gap.…”

A model of a hybrid electric vehicle including an aftertreatment system is developed and validated. The model describes a vehicle with the same parallel hybrid architecture that is commonly used in commercial heavy duty vehicles and is validated using data gathered from vehicles during real world driving. The goal with the model is to describe the main dynamics of the system and give accurate estimations of fuel consumption and emissions while at the same time keeping simulation times short. The model consists of several sub components, out of which the most important ones are: combustion engine, electric motor, aftertreatment system, driveline, and vehicle chassis. The different components are interchangeable making it possible for the user to change specific components to make the model fit their needs.
