Steady-state comparison of torque vectoring and vehicle tilt influence on narrow car steering characteristics

Abstract

Article compares the roll-to-curve and torque vectoring impact on a steering characteristics. The comparison is based on an adopted for tilt mathematical model with two DOFs. The lateral tire forces are a function of the tire sideslip angle and the angle of tilt. The first chapter contains a description of the vehicle for which a series of road tests and simulations was carried out. Next chapter contains an experimental verification of the mathematical model of the vehicle and the simulation tests carried out. The paper describes the mathematical model of the vehicle used to perform the simulation. The next chapter contains the description and results of steady-state simulations examining the effect of differentiation of driving forces on the steering characteristics and the impact of tilt angle on the steering characteristics. The article ends with the chapter containing the conclusions.
