Mastinu, F. Braghin, F. Cheli, M. Corno, & S. M. Savaresi (Eds.), 16th International Symposium on Advanced Vehicle Control (pp. 200–206). Springer. https://doi.org/10.1007/978-3-031-70392-8_29
The influence of the drive torque distribution of an AWD vehicle with individual motors at the front and rear axles on the handling and stability properties is investigated. By applying bifurcation analysis methods, different types of loss of stability at combined longitudinal and lateral acceleration are identified. The impact of the drive torque distribution on the stability boundaries in the GG diagram is examined, and the related stable acceleration envelope is compared to the envelope derived from applying optimisation methods. Representative corresponding handling characteristics are compared and discussed.
