Abstract The paper examines the problem of developing cost effective teaching and research tools for automotive dynamics. Different available solutions are presented and the need of human feedback is emphasized. Based on the demands from industry and academia (benchmarking, virtual prototyping, comparative testing of alternative technologies, development and tuning of the automotive control etc.) a solution is proposed. At the core of the proposed tool is a H2iL (humanand- hardware-in-the-loop) simulator based on an electric vehicle. An architecture is elaborated for the simulator and the proof of concept is done in three steps.

Temperature Operating

Electrical motor bearings for use in automotive control units are sometimes exposed to high-temperature operating conditions. Therefore, these bearings are sometimes packed with fluorine grease in order to meet the demand for long service life performance. In recent years, there is growing demand for lower initial torque in these same bearings without sacrificing service life performance. This paper describes the effects of fluorine grease containing silica nanoparticles on initial bearing torque of electrical motor bearings. Silica nanoparticles are effective in helping to reduce amounts of initial bearing torque and help stabilize bearing torque due to improved channeling characteristics.

Multiple Regions

A hardware-in-the-loop (HiL) test is performed to verify the software functions mounted on automotive electronic control units (ECUs). However, the characteristics of HiL test limit the usage of common debugging techniques. Meanwhile, the logs of how the program uses memory can be utilized as debugging information collected by the controller area network (CAN). However, when the 32 KB memory is observed with 10 ms period, about 96% of the data on each cycle is lost, since the CAN only can transfer 1.25 KB of data at each cycle. Therefore, to overcome the above limitations, in this study, the memory is divided into multiple regions to transmit generated data via CAN. Next, the simulation is repeated for the each divided regions to obtain the different areas in each simulation. The collected data can be visualized as update information in each cycle and the cumulative number of updates. Through the proposed method, the ECU memory information during the HiL test was successfully collected using the CAN; the transmission is completed without any loss of data. In addition, the data was visualized in images containing the update information of the memory. These images contribute to shortening the debugging time for developers and testers.
