Realistic models for ground vehicle attitude control need to take into account coupling effect between steering wheel input and suspension system. Control design based on vehicle models such as bicycle models can work for small operation range, but can become critical when the effects of suspension become important. This paper deals with investigation of coupling effect between steering wheel input and suspension system and the result of those effects on the orientation of the vehicle. The goal of this investigation being effective control designing for attitude control of the vehicle. Most of control methods nowadays employed for attitude control of vehicles are active anti-roll bars, active steering and electronic brake mechanism. In this paper, only vertical actuators locating on each suspension are used to control the attitude of the vehicle due to any given steering input during cornering. The resulting model is a set of highly nonlinear equations that allow studying deeply all aspect of vehicle dynamics, including ride comfort, handling, road holding, and attitude control of the chassis during straight path motion as well as cornering. The model developed here is 15 degrees of freedoms (d.o.f.) model, 6 d.o.f. for the chassis, 2 × 4 d.o.f. for each of the four wheels and 1 d.o.f. for the steering wheel. A controller is designed and simulations are carried out.
