Resilient Fault and Attack Detection of DCT Vehicles Using Parity Space Approach

Dual clutch transmissions (DCTs) have provided significant reduction in torque discontinuities, interruptions, fuel economy and emissions of the vehicles. However, DCTs are often prone to inoperative in case of operating faults and cyber-physical system (CPS) attacks, the safety and security criticality are high. In this paper, we investigate a parity space method to design a resilient fault and attack detection (RFAD) system for DCT vehicles. In particular, an optimal sensor attack is studied to make the system measurement track the desired value of the adversary but not trigger the alarm of the parity vector-based residual generator. To detect such a malicious attack, the parity space-based FD technology is further investigated to generate a resilient parity vector-based residual generator and residual evaluation, and the function of RFAD is realized by a novel detection logic. To account for the proposed method, a benchmark simulation of vehicle model and environments from AMESim are used..
