“…In Simple Vehicle Model (Figure 1) the vehicle is considered as one rigid body which moves along an ideally even and horizontal road. At each axle the forces in the wheel contact points are combined in one normal and one longitudinal force [34]- [36]. [34] By neglected aerodynamic forces (drag, positive and negative lift), the equations of motions in the x-, z-plane are presented in the following mathematical forms ̇ where v derivate indicates the vehicle acceleration, m is the mass of the vehicle, a1+a2 is the wheel base, and h is the height of the center of gravity.…”

In this paper, a review is presented on automotive vehicle dynamics modeling. Applied vehicle dynamics models from various application fields are analyzed and classified in the first section. Vehicle dynamics models may be simplified because of different reasons: several control/estimation/analysis methods are suitable only for simplified models (e.g. using control-oriented models), or because of the computational cost. Detailed/truth models of vehicle dynamics represent another field of vehicle dynamics modeling, these models play an important role in the virtual prototyping of vehicles. In the second section, the main modeling considerations of vehicle dynamics are presented in longitudinal, lateral and vertical directions. Various physical effects must be considered in the case of vehicle dynamics modeling, a lot of these effects are significant only in a specific direction of the vehicle body, which is the main potential of model simplification. The section presents vehicle modeling considerations in all of the three translational directions of the vehicle body.

A járműdinamikai modellek a modell egyszerűsítése alapján két csoportra oszthatók. Vannak egyszerűsített modellek, amelyek során elhanyagolásokkal élünk: ezek jellemzően a hossz-, oldal- és függőleges irányok közül nem tartalmazzák az összes irányt. Az egyszerűsített modellekre több ok miatt is szükség lehet: vannak szabályozási, becslési, valamint analízis módszerek, amelyek csak egyszerűsített modellek alapján alkalmazhatók, valamint a számítási idő miatt is szükség lehet egyszerűsítésre. Az egyszerűsített modellek mellett léteznek valós modellek, amelyek célja egy virtuális plant biztosítása a valós járműről, virtual prototyping alapú fejlesztésekhez. Ebben a cikkben egy rövid bevezetés után néhány egyszerűsített járműmodell kerül bemutatásra.

“…That is, the longitudinal dimension of the vehicle is several times its lateral dimension. While the assumption of a null cross-coupling between the lateral and longitudinal vibration modes of the vehicles has been adopted previously [9,10], we consider it necessary to experimentally validate such an approach in the case of a sloshing cargo. B.…”

Modelling of a Partially Loaded Road Tanker during a Braking-in-a-Turn Maneuver

Road safety depends on several factors associated with the vehicle, to the infrastructure, as well as to the environment and experience of vehicle drivers. Concerning the vehicle factors influencing the safety level of an infrastructure, it has been shown that the dynamic interaction between the carried liquid cargo and the vehicle influences the operational safety limits of the vehicle. A combination of vehicle and infrastructure factors converge when a vehicle carrying liquid cargo at a partial fill level performs a braking maneuver along a curved road segment. Such a maneuver involves both longitudinal and lateral load transfers that potentially affect both the braking efficiency and the lateral stability of the vehicle. In this paper, a series of models are set together to simulate the effects of a sloshing cargo on the braking efficiency and load transfer rate of a partially filled road tanker. The model assumes the superposition of the roll and pitch independent responses, while the vehicle is equipped with Anti-lock braking System brakes (ABS) in the four wheels. Results suggest that cargo sloshing can affect the performance of the vehicle on the order of 2% to 9%, as a function of the performance measure considered. A dedicated ABS system could be considered to cope with such diminished performance.
