A Stability Estimation Approach in Vehicle Planar Motion Considering Longitudinal Dynamics

Abstract:

A stability estimation approach is proposed to support complementary stability criterion design in vehicle planar motion. The comprehensive effect of tangential force and axle load transfer on tire cornering characteristics is considered corresponding to the longitudinal dynamics effects. The effectiveness of different stability concept is discussed in terms of the physical meaning of state variables in 3DOF differential systems. Based on the sense of technical stability, the 3DOF model is simplified according to longitudinal dynamics characteristic within definite observation time interval. The central equilibrium points continuum properties of the simplified model can be used to estimate the vehicle behavior in planar motion.
