Due to some key state parameters of vehicle handling stability control are difficult to measure directly, the state optimization estimation algorithm of multi-sensor linear combination based on Strong Tracking Filter (STF) was proposed. Four degrees of freedom vehicle nonlinear dynamics model including longitudinal, lateral and roll motion were established. With the estimator of multi-sensors i...

In this paper, a map-based optimal energy management strategy is proposed to improve the consumption economy of a plug-in parallel hybrid electric vehicle. In the design of the maps, which provide both the torque split between engine and motor and the gear shift, not only the current vehicle speed and power demand, but also the optimality based on the predicted trajectory of vehicle dynamics ar...

As a representative example of a C continuous system, a four-dimensional model of the dive-plane dynamics of the supercavitating body shown in Figure 1 is considered. This model includes a dominant, nonsmooth nonlinearity associated with the planing force [1,2]. The original non-smooth system is approximated by a smooth counterpart, and it is examined as to how well the smooth system captures t...

This paper deals with improving comfort and handling for a ground vehicle through the coordinated control of different active systems available in passenger cars, e.g., electronic stability control, active roll control and engine torque control. The authors first describe separate control systems, each with its logic, showing advantages and limits, then propose various possible integrations, ai...

Model based simulation in vehicle system dynamics relies on advanced methods for model setup, robust and efficient numerical solution techniques and powerful simulation tools for industrial applications. Most frequently the mechanical components are described by rigid or flexible multi-body system models that interact with electrical, hydraulic and other system components [1, 2], see also [3] f...

Original scientific paper In order to improve conceptual phase of vehicle development, this research is focused on development of new multi-objective optimization model for determining the optimal parameters of the suspension system. In this research emphasis is on the development of suspension system from the viewpoint of full vehicle dynamics behaviour. The new optimization model consists of ...

This paper presents a motorcycle direct dynamic formulation by the Jourdain’s principle approach. This vehicle is considered as an assembly of six rigid bodies and the resulting equation of motion allows to simulate 11 Degrees of Freedom (DoF). The vehicle geometry is described and a step by step procedure is introduced to evaluate the kinematics and the generalized efforts of the considered ve...

An analysis of navigational accuracy when influenced by ground vehicle dynamics is presented. Tests beds outfitted with various sensor suites were used to collect data when normal and extreme driving maneuvers are executed. The data was run through an extended Kalman filter to produce a navigation solution. The Kalman filter inputs varied on each test bed, using both automotive and tactical gra...
