Automotive Architecture

All of this also requires some form of mechanical articulation that can allow relative motion of the wheels and chassis while maintaining wheel orientation to preserve vehicle control, stability and tracking. Exactly how this is done varies significantly. Older systems included dependent suspensions that had a stiff axle housing connecting the two wheels and keeps them in a fixed relative orientation. With the exception of trucks, these systems have been largely replaced by independent suspension that allow each wheel assembly to move independently, and so better accommodate uneven road conditions and improve handling. Though, to accommodate larger cabin space or reduce cost, a semi-independent system can sometimes be used on the rear axle, with the two wheels impacting each other but allowed to move largely independently, such as a twist beam axle. Nevertheless, just about every contemporary car has independent front suspension and a growing number also have independent rear suspension.

With independent suspension, each wheel is suspended independently of the others. Some vehicles have independent suspension on the front wheels only — this is called independent front suspension (IFS). At the rear it is called independent rear suspension (IRS). When one wheel of a car with independent suspension hits a bump, only that wheel is deflected upward; the other wheels are not affected and the car remains level.

In order to study car ride and handling performance, different models are reported in the literature to simplify the complicated vibratory system of the vehicle. A half-car model with independent suspension system forms a four-degrees-of-freedom model. Adding the driver seat stiffness, damping, and weight to the half car model, a five-degrees-of-freedom model is developed. A model with five degrees of freedom and a passive suspension system adapted from (Bouazara 1997) is employed, as shown in Figure 2.
