Abstract
To suppress a negative effect brought by introducing hub motor in vertical vibration of the body and that of a hub motor, a suppressing vertical negative effect algorithm of in-wheel electric vehicle is proposed based on hybrid variable universe fuzzy control (VUFC). Vertical accelerations of the body and that of the hub motor are taken as optimization objects, and to control the main suspension damper and in-wheel damper simultaneously, the semi-actively VUFC algorithm is adopted to improve vertical vibration characteristics effectively. The simulated results show that the peak and root mean square (RMS) of body vertical acceleration (VA) are optimized by 21.0% and 19.6%, respectively, after optimization compared to the original in-wheel electric model, the peak and RMS of hub motor VA are optimized by 30.1% and 32.5%, respectively, and the vertical negative effect is suppressed significantly.
