Assessment of Energy Consumption Characteristics of Ultra-Heavy-Duty Vehicles under Real Driving Conditions

Fuel Consumption Optimization of Heavy-duty Vehicles: an Analytical Approach

In this paper, we establish a mathematical framework that allows us to optimize the speed profile and select the optimal gears for heavy-duty vehicles. The key idea is to solve the analogous boundary value problem analytically for a simple scenario (linear damped system with quadratic elevation profile) and use this result to initialize a numerical continuation algorithm. Then the numerical alg...

The Assessment of The Emission Level From Heavy- Duty Truck Under Actual Operating Conditions

The paper presents an analysis of the gaseous exhaust emissions along with an analysis of the size and mass distribution of particulate matter from a Euro V compliant road tractor. The vehicle was fitted with an engine of the displacement of 15,6 dm, maximum power output 412 kW generating a maximum torque of 2700 Nm (1991 lb/ft). For the tests the authors used portable exhaust emission analyzer...

Simulating Energy Consumption of Auxiliary Units in Heavy Vehicles

Models that can be used to analyse the fuel saving potential of electrically driven auxiliaries in heavy vehicles are presented. With the purpose of evaluating the influence on fuel consumption from various concepts and control principals, a model library is developed in the modelling language Modelica. The library contains a mixture of models developed from physical principles and models fitte...

Literature Review: Real-world Fuel Consumption of Heavy-duty Vehicles in the United States, China, and the European Union

Decentralized Diagnosis in Heavy Duty Vehicles

Fault diagnosis is important for automotive vehicles, due to economic reasons, such as efficient repair and fault prevention, and legislative reasons, mainly safety and pollution. Embedded systems in vehicles includes a large number of electronic control units, that is connected to each other via an electronic network. Many of the current diagnostic systems use pre-compiled diagnostic tests, an...
