Design and Experiment of Simple Dynamometer for Vehicle Cybersecurity Research

Abstract

This study describes the design of a simple dynamometer, the creation of an environment for vehiclecybersecurity research, and the results of experiments performed on a real vehicle. Cybersecuritythreats in the information technology (IT) environment have spread to vehicles owing to the convergenceof vehicles and IT. Accordingly, a variety of research on vehicle cybersecurity has beenconducted. Vehicle cybersecurity threats are made to vehicles in motion to trigger casualties. Therisk of vehicle cybersecurity threats has been proven in many studies, and protection technologyhas been also proposed. However, in these studies, the experimental environments were such thatthe vehicle was simply placed above the ground or on restricted road conditions with no traffic ofvehicles. In these experimental environments, unexpected situations can threaten the safety of theexperimenter. Furthermore, because the driving environment on actual roads cannot be simulated,the vehicle’s functions cannot operate normally. In this study, therefore, we proposed and designeda simple dynamometer to ensure the safety of the experimenter and created the same environmentas that of the actual vehicle driving. The designed technology was then applied to a real vehicle todemonstrate the safety and practicality of the designed experimental environment.
