LPV feedforward control of semi-active suspensions for improved roll stability

“…The lateral acceleration needed as input to (12) is obtained by a linear single track model processing the steering angle input of the driver. Detailed presentations of the linear single track model are given in [1,36]. The single track model has been parametrized with the lateral acceleration and yaw rate measurements of two reference manoeuvres: firstly a constant radius cornering with increasing vehicle speed and secondly a manoeuvre consisting of several steering angle step inputs at a constant vehicle velocity.…”

Investigating and Coordinating Safety-critical Feature Interactions in Automotive Systems Using Simulation

“…Speed A depends on the acceleration of the vehicle under consideration (through a differential equation). According to [13], in this model only longitudinal motion can be simulated. Simulating the steering angle for overtaking maneuvers, for example, would require a more elaborate model, but this is out of the scope of our investigations.…”

Dynamic response multiobjective optimization of road vehicle ride quality—A computational multibody system approach

“…A review of the existing software packages allowing fast and high precision kinematics and dynamics analysis of the road vehicles shows that most of them use MBS methodology. 2,3 The software packages have been usually used for vehicle dynamic simulation or vehicle control applications. It has been also shown that a computational MBS could be used for design optimization of vehicle dynamic subsystems.…”

“…The LPM models do not consider the suspension configuration and linkage geometry for simulation, analysis, and optimization of ride dynamics. A wide variety of LPMs has been developed 11 and they include quarter, 6,8 single-track half-car (bounce-pitch), 3,6–8 two-track half-car (bounce-roll), 11,12 and full-car 3,13 models. Comparatively, DPM considers the configuration and linkage geometry of the suspension.…”

“…Comparatively, DPM considers the configuration and linkage geometry of the suspension. 1,3 In the literature, the focus of DPMs has been mostly given to Double Wishbone (Double A-arm), 3,14 Macpherson, 3,15 and Multi-link 3,16 suspension systems. Researchers have mainly used the models of these suspension systems for kinematic analysis.…”
