In this paper, we propose that a model based design for an electric motor cycle system using ASM(Automotive Simulation Models). Before prototyping a realistic electric motorcycle, a reliable simulation program is required to test the capacities of the power sources and optimize the parameters of an electric motorcycle. Because ASM is based on Simulink, we can design the drivetrain and powertrain of the vehicle model systems easily. To verify the electric motorcycle system analysis of design parameters such as maximum power, capacity, state of charge and slope angle is carried out by the simulation and experimental method. The predicted results by the development model were in good agreement with the experimentally obtained results. Therefore, the proposed electric motorcycle model can effectively reduce the expenses during the designing of an electric motorcycle system.

This paper suggests application of a wire in a helical form to a connector for automotive Wi-Fi (Wireless Fidelity) networks. Since the helical mean radius, helical pitch, helical wire radius, and helix wire distance are important design factors. An analysis of the design can be used to determine the most suitable dimensions of a connector for an automotive Wireless Access Vehicle Environment (WAVE) in which a helical wire had an insertion loss of −0.43 dB to −0.115 dB in the 5.9 GHz band. The resulting insertion loss indicates an improvement of 36-83% in performance compared to an existing FAchKreis Automobile (FAKRA) connector. Therefore, the result of the connector can be useful for designing an suitable connector for automotive communication in high-frequency bandwidth.

The aim of this study is to prepare polypropylene (PP) / nickel coated carbon fiber (NiCF) or stainless steel (SUS) fiber composites possessing electromagnetic interference (EMI) shielding effectiveness (SE). A series of conductive composites were prepared by the melt blending method. The EMI SE of conductive composites is 45 dB over a wide frequency range up to 100 MHz, which is higher than that of PP/talc composite used automotive interior parts, viz. 0 dB.
