Abstract
Increasing the rigidity of the torque sensor is effective in enhancing vehicle responsiveness. However, since the rigidity of the system changes, the vibration transmission characteristics also change significantly. Therefore, we proposed EPS control that makes it possible to shape the vibration transmission characteristics. It was shown that the vibration transmission characteristics can be changed by extracting a specific frequency of the torque signal and adding the assistive current based on this signal. As a result, it was confirmed that the torque sensor can be made high rigidity and the vehicle responsiveness is enhanced.
