The dwindling energy resources and the compliance of international climate protection goals lead to a rethink in the automobile sector. One result of this rethink is the increasing distribution of electric vehicles in the last years. This development includes a new challenge for the training sector. For example, the implementation of a high-voltage system into automobiles involves a new hazard potential for people, who work on electric vehicles. Therefore, the employees in the areas of vehicle repair trade, rescue services, towing services, and other relevant sectors need a good qualification for working on electric vehicles. On the one hand, a lot of specialized training programs have already been developed in the area of academic education. On the other hand, there is a great need of training programs for professionals (e.g. motor mechanics, firefighters). Hence, this paper clarifies the current requirements in the education sector and the new hazard potential by working on electric vehicles. Moreover, an approach for the development of a specialized training program for working on electric vehicles is presented in this paper as well. The focus of this training program is on the improvement of the learning process by a blended learning concept with an adaptive modular design.

“…This allows the transfer of driving sensations such as maneuvering and acceleration to the driver, providing a realistic driving experience. These simulators can be used to measure the dynamic responses of the driver [1][2][3][4][5]. Linear actuators are typically used to connect the vehicle simulator to appropriate configuration, allowing the vehicle simulator to be considered as a parallel manipulator.…”

This article presents a topology optimization of the motor mounting bracket in a 2-degree-of-freedom (2 DoF) vehicle simulator that is enhanced by the driving scenari-os. Firstly, a 14 DoF passenger reference application model is determined in the Sim-ulink environment. Then, common driving scenarios (Constant Radius, Double Lane Change, Fishhook, Increasing Steer, Sine with Dwell and Swept Sine) are run on 14 DoF vehicle models to test the dynamic performance of the vehicle. During the anal-ysis, accelerations in the XYZ axes are logged, and the minimum and maximum ac-celeration values on each axis are grouped separately for each driving scenario. Next, the concept design of 2 DoF vehicle simulators is created. The obtained accelerations from the driving scenarios are then run on 2 DoF vehicle simulator in the Solidworks simulation environment, and stress and deformation on the 2 DoF vehicle simulator are analyzed. During this analysis, linear actuator and axis forces are calculated ac-cording to the reaction forces on the vehicle simulator. Under the determined axial forces, the brackets are subjected to topology optimization. The obtained generative design of the bracket is reshaped by post-processing for sustainable production. The shape-optimized bracket is run again on the 2 DoF vehicle simulator with the ob-tained acceleration values from the driving scenarios, and the study is completed by performing stress and deformation analysis.

“…In most educational centers, this practical experience has been carried out only by means of computer simulation models [2,3], without the benefits brought by the actual machines and by the performance of field tests in the laboratory [4].…”

Educational Project for the Teaching of Control of Electric Traction Drives

et al. 2015

Electric vehicles constitute a multidisciplinary subject that involves disciplines such as automotive, mechanical, electrical and control engineering. Due to this multidisciplinary technical nature, practical teaching methodologies are of special relevance. Paradoxically, in the past, the training of engineers specializing in this area has lacked the practical component represented by field tests, due to the difficulty of accessing real systems. This paper presents an educational project specifically designed for the teaching and training of engineering students with different backgrounds and experience. The teaching methodology focuses on the topology of electric traction drives and their control. It includes two stages, a simulation computer model and a scaled laboratory workbench that comprises a traction electrical drive coupled to a vehicle emulator. With this equipment, the effectiveness of different traction control strategies can be analyzed from the point of view of energy efficiency, robustness, easiness of implementation and acoustic noise.
