Electric vehicles (EVs) have become more intelligent and smarter with the incorporation of electronics and software which depends on sensor signals and networks. For better performance of the connected and autonomous EVs, several sub units have to be controlled in a centralized manner. However, this has made it more vulnerable to malicious cyber-attacks, since the sensors and networks are more prone to cyber-attacks. In this paper, the impact of various sensor data integrity attacks on torque controlled permanent magnet synchronous motor (PMSM) based electric drive system (EDS) has been studied through MATLAB simulations. Different sensor data integrity attacks are modelled and analysed with the help of predefined performance metrics for PMSM-based EDS under different torque control strategies. The simulations and analysis can help in understanding the impacts of sensor data integrity attacks on EDS and hence can pave way for its effective mitigation through predictive control approach.
