    • Battery Ageing as Part of the System Design of Battery Electric Urban Bus Fleets 

      Ufert, M.; Baker, B. (БНТУ, 2020)
      The lifetime of traction battery systems is an essential feature of the economy of battery electric urban bus fleets. This paper presents a model for the analysis and prediction of the lifetime of urban electric bus batteries. The parameterization of the model is based on laboratory measurements. The empirical ageing model is an integral part of a three-stage battery model, which ...

    • Comparing Fuel Consumption and Emission Levels of Hybrid Powertrain Configurations and a Conventional Powertrain in Varied Drive Cycles and Degree of Hybridization 

      Maddumage, W. U.; Abeyasighe, K. Y.; Perera, M. S. M.; Attalage, R. A.; Kelly, P. (БНТУ, 2020)
      Hybrid electric powertrains in automotive applications aim to improve emissions and fuel economy with respect to conventional internal combustion engine vehicles. Variety of design scenarios need to be addressed in designing a hybrid electric vehicle to achieve desired design objectives such as fuel consumption and exhaust gas emissions. The work in this paper presents an analysis ...

    • How to Make the Charging Simple, Convenient and Efficient 

      Cheng, W.; Wang, Y. (БНТУ, 2020)
      With the large-scale application of electric vehicles (EV) in the world and also in China, the contradiction between the EV and charging stations has become more and more prominent. People always cannot easily find the charging stations or when they find them finally found they do not work. To connect the vehicle, charging station/pile and end-users for making the charging simple, ...

    • Imitating a Safe Human Driver Behaviour in Roundabouts Through Deep Learning 

      Cervera, A. S. J.; Alonso, F. J.; Garcia, F. S.; Alvarez, A. D. (БНТУ, 2020)
      Roundabouts provide safe and fast circulation as well as many environmental advantages, but drivers adopting unsafe behaviours while circulating through them may cause safety issues, provoking accidents. In this paper we propose a way of training an autonomous vehicle in order to behave in a human and safe way when entering a roundabout. By placing a number of cameras in our ...

    • Improving the Brake Control Effectiveness of Vehicles Equipped with a Pneumatic Brake Actuator 

      Bogomolov, V.; Klimenko, V.; Leontiev, D.; Ryzhyh, L.; Smyrnov, O.; Kholodov, M. (БНТУ, 2020)
      This paper proposes a way to determine a rational connection between a two-section or three-section brake valve and the main brake system circuits of a wheeled vehicle equipped with simplex or duo-duplex brake gears. The aim is to determine a rational option to connect main brake system circuits with a brake valve to guarantee the maximum effectiveness of an emergency brake system ...

    • Laser Research of the Fuel Atomization Process of Internal Combustion Engines 

      Stezycki, P.; Kowalski, M.; Jankowski, A.; Slawinski, Z. (БНТУ, 2020)
      The paper presents test methods (mechanical, electrical and optical) for the fuel spray research in combustion engines. Optical methods, imaging and non-imaging can be used in laboratory and engine tests. Imaging methods include flash photography and holography. Their use is limited to testing droplet dimensions larger than 5 μm. Imaging methods have an advantage over non-imaging ...

    • Robust Design of Suspension System with Polynomial Chaos Expansion and Machine Learning 

      Gao, H.; Jezequel, L.; Cabrol, E.; Vitry, B. (БНТУ, 2020)
      During the early development of a new vehicle project, the uncertainty of parameters should be taken into consideration because the design may be perturbed due to real components’ complexity and manufacturing tolerances. Thus, the numerical validation of critical suspension specifications, such as durability and ride comfort should be carried out with random factors. In this ...
