In this paper, a traction control system has been designed in order to improve vehicle traction on slippery roads. First, a nonlinear model has been formulated from the vehicle longitudinal dynamics, the drivetrain model and the wheel motion. Then, a Takagi-Sugeno (TS) fuzzy representation has been proposed in order to take into account the nonlinearities of the obtained model and to simplify the...
In this paper, a fuzzy proportional integral (PI) state feedback controller has been developed in order to improve vehicle traction on slippery roads. A nonlinear model has been formulated from the vehicle longitudinal dynamics, the drivetrain model and the wheel motion. Takagi-Sugeno (TS) representation has been used in order to take into account the nonlinearities of the obtained model and to simplify...
This paper introduces a methodology for robust control of vehicle dynamics. The vehicle lateral behavior with roll dynamics is described by Takagi-Sugeno (TS) model. A fuzzy observer is first developed to estimate the vehicle sideslip angle as well as the roll parameters using the yaw rate measurement, while taking into account the road bank angle and the unmeasurable premise variables of the TS model...
This paper describes a methodology for estimating both vehicle dynamics and road geometry using a Fuzzy unknown input observer. Vehicle sideslip and roll parameters are estimated in presence of the road bank angle and the road curvature as unknown inputs. The unknown inputs are then estimated using the observer results. The used nonlinear model deduced from the vehicle lateral and roll dynamics with...
This paper deals with the H∞ robust output control for vehicle dynamics where the sideslip angle is unavailable for measurement. This study uses the multiple model approach to represent the vehicle model. The road adhesion conditions change and modeling errors are taking into account by introducing uncertainties. Thus, giving a nonlinear vehicle model, its representation by a multiple model is discussed...
In this paper an approach for detecting impending rollover is proposed. The method includes an algorithm based on Takagi-Sugeno (TS) fuzzy observer to prevent rollover of the vehicle when road adhesion conditions change. To design such observer, we take into account that roll rate can be measured easily by sensor, but roll angle is not measured. The proposed method allows estimating the roll angle...
