HILS Test Bench를 이용한 전자브레이크(EMB)의 센서 Fault Injection Test 및 동역학 해석 검증

In recent, the eco-friendly Green cars such as Hybrid-Electronic vehicles, Fuel Cell vehicles and Electronic vehicles have been researched in major car makers. To response this electronic vehicle, the electronic brake systems such as EMB(Electro-Mechanical Brake) are receiving a lot of interest in automotive industry due to their flexibility in controlling vehicle motion. So the establishments of assessment technology for performance and reliability of electronic brake are needed because of ISO 26262. In this study, the evaluation method of fault injection test for sensor fault using test bench are introduced. And vehicle dynamic simulation also conducted using brake torque measured in fault injection test. The purpose of the simulation is to verify the effect of fault-tolerant algorithm on vehicle stability.
