“…In the presented work, a regression model based on the Radial Basis Function with a multi-quadratic kernel was used. Therefore, Equation (25) should be treated only as a demonstration example showing a general procedure of the surface response function derivation. The fitting quality of the response models is featured by the statistic factors R 2 and R 2 adj [33][34][35] whose target value is 1 (100% good fitting).…”

“…In transient simulations that are presented in Appendix C, the ICESM is propelled by the engine brake running in speed mode. Likewise, transient cold start functionality can be modeled if the ICESM is coupled to the model of the cooling and lubrication circuit as presented in [25], whereas these simulations are outside of the scope of this paper. Figure 1 additionally presents available measurement data applied for the ICESM calibration and their positions (labeled positions 1, 2, .…”

“…The engine cooling domain is inherently a part of the engine. The engine cooling domain interacts with the cooling and lubrication circuit domain presented in [25] via the heat flux between the engine block structure and the cooling as well as lubrication fluids. Therefore, the ICESM uses the coolant and oil temperature specified in the temperature boundaries as boundary conditions.…”

Abstract:The paper outlines a procedure for the computer-controlled calibration of the combined zero-dimensional (0D) and one-dimensional (1D) thermodynamic simulation model of a turbocharged internal combustion engine (ICE). The main purpose of the calibration is to determine input parameters of the simulation model in such a way as to achieve the smallest difference between the results of the measurements and the results of the numerical simulations with minimum consumption of the computing time. An innovative calibration methodology is based on a novel interaction between optimization methods and physically based methods of the selected ICE sub-systems. Therein physically based methods were used for steering the division of the integral ICE to several sub-models and for determining parameters of selected components considering their governing equations. Innovative multistage interaction between optimization methods and physically based methods allows, unlike the use of well-established methods that rely only on the optimization techniques, for successful calibration of a large number of input parameters with low time consumption. Therefore, the proposed method is suitable for efficient calibration of simulation models of advanced ICEs.

“…In addition, a simplified, holistic vehicle model is proposed, which is mainly based on experimental measurements. Similarly, [16] developes a transient vehicle model with diverse submodels and corresponding interactions. Again, the application of an electrical water pump results in a fuel saving of about 0.75 to 1.1 percent.…”

Abstract:With the increasing demands for vehicle dynamic performance, economy, safety and comfort, and with ever stricter laws concerning energy conservation and emissions, vehicle power systems are becoming much more complex. To pursue high efficiency and light weight in automobile design, the power system and its vehicle integrated thermal management (VITM) system have attracted widespread attention as the major components of modern vehicle technology. Regarding the internal combustion engine vehicle (ICEV), its integrated thermal management (ITM) mainly contains internal combustion engine (ICE) cooling, turbo-charged cooling, exhaust gas recirculation (EGR) cooling, lubrication cooling and air conditioning (AC) or heat pump (HP). As for electric vehicles (EVs), the ITM mainly includes battery cooling/preheating, electric machines (EM) cooling and AC or HP. With the rational effective and comprehensive control over the mentioned dynamic devices and thermal components, the modern VITM can realize collaborative optimization of multiple thermodynamic processes from the aspect of system integration. Furthermore, the computer-aided calculation and numerical simulation have been the significant design methods, especially for complex VITM. The 1D programming can correlate multi-thermal components and the 3D simulating can develop structuralized and modularized design. Additionally, co-simulations can virtualize simulation of various thermo-hydraulic behaviors under the vehicle transient operational conditions. This article reviews relevant researching work and current advances in the ever broadening field of modern vehicle thermal management (VTM). Based on the systematic summaries of the design methods and applications of ITM, future tasks and proposals are presented. This article aims to promote innovation of ITM, strengthen the precise control and the performance predictable ability, furthermore, to enhance the level of research and development (R&D).
