Influence of Magnetic Field of e-Vehicles to Brainwaves and Drivers' Decision-making

Abstract

The percentage of electric vehicle's market share increased rapidly these years. With direct current power supply, the exposure level of the magnetic field strength within electric vehicles is relatively high compared to other vehicles. The aims of this study were to investigate the impact of B-field of e-vehicles and drivers' decision-making. Three tasks related to driver's decision making are designed for this experiment. A static b-field with 350?T field strength is used in this experiment. Brainwave of objects is also measured during the experiment as a tool to clarify any psychological impact are made. Student T-tests have been done to analyse the result. In this study, most subjects performed worse under the exposure of static B-field (82.5% in "Lane Change Test" while turning, 70.5% in "Direct Reaction Time"). However, P-value of most of the result datasets is higher than 0.05, which indicate that static b-field within e-vehicle may only have a very slight impact on the performance of driver's decision making.
