“…The development uses advanced simulation and modelling tools to realise a system with precise modelled functions that work together with physical hardware and processes. The virtualisation allows testing and validation of parameters and function guarantying highly quality [72][73][74]. However, several factors, as real-time computational complexity and calibration efforts, might lead to select faster and less-expensive techniques.…”

The adoption of Engine-in-the-loop technology shows real behaviour. This study presents a test runs simulation platform with real engine data. In addition, a test bench model is a demand approach that offers a significant potential to provide an excellent reproducibility of test runs. The platform includes the data integration to upgrade tests run and a comparison with previous results using the advancing control techniques designed. The dynamometer system presents significantly non-linearity. The adaptive control approach, integrated into the Model Predictive Control on the vehicle, allows increasing the tests run performance. The results show how the real data can improve performance and the validation of the system integrating the updated driving cycle and maintaining EiL approach. The conclusion showed the significant benefits regarding the control methods used.

“…The vehicle dynamics model calculates the 3-D vehicle drive state for each time step considering simulation parameters, as well as position-and time-dependent inputs. Therefore, a multi body system based on the guidelines introduced in [36] is computed, which has been validated in [37] and [38]. The overall structure of the vehicle dynamics model is displayed in Fig.…”

In order to reduce automotive development times and costs, particular development tasks are rescheduled to earlier program phases (frontloading) by applying hardware-in-the-loop (HiL) tests. However, there is a shortage of studies considering HiL tests for function developments considering the thermal behavior of electric drives. This article shall be a first step toward closing this gap. A real-time co-simulation of a battery electric vehicle and a driver model are developed and connected to an electric traction machine at a laboratory test bench. A thermal derating function is designed and calibrated at this test setup.In particular, linear derating functions with different gradients are implemented and tested for high load performances during a track race, and the trade-off between energy demand and the lap time is determined. Larger gradients of thermal derating functions lead to shorter lap times and higher energy demands. Thus, for this case study, an increase of the gradient of the thermal derating function by a factor of two results in a lap time improvement of 2.3% and a higher energy demand of 4.7%. The test results demonstrate how HiL setups offer a favorable testing scenario to calibrate thermal derating functions of electrified powertrains in early development phases.

“…As an example, Baake et al [16] describe the homologation of ESC systems for vans from Mercedes-Benz in collaboration with Bosch and IPG CarMaker: Using what are known as master cars, a vehicle model was created in CarMaker, and these master cars were used to collect reference data on the basis of which the simulation model was validated. This enabled the simulation-based recommendation for the approval of further vehicle variants with different settings.…”
