This paper presents a novel estimation and identification approach for lateral vehicle dynamics. The algorithm leverages on Linear Fraction Transform (LFT) reformulation of tyre models, allowing simple computationally efficient inclusion complex nonlinear dynamic like, example, two-wheels, four-wheels or single-track as model, Pacejka, brush Fiala model. As result, this technique can be easily ...

Abstract: This paper presents an active Fault Tolerant Control (FTC) strategy for vehicle lateral dynamics. A bicycle vehicle model using small angle approximations is used to represent vehicle behavior. Firstly, the nonlinear lateral vehicle dynamics is approximated by a TakagiSugeno fuzzy model with parametric uncertainties and sensor faults. Secondly a robust H∞ output controller is used. A ...

In conventional bridge health monitoring, a number of sensors are deployed on a bridge directly for detecting its various dynamic properties. This is so called “direct method”. But the drawbacks of the direct method are: laborious deployment of sensors, time-consuming, and not portable. Following the previous Yang’s works (2004) in indirect method by using a passing test vehicle as a message re...

A control strategy based on H?-type static output feedback combined with dynamic feed-forward is proposed to improve the high-speed lateral performance of an A-double combination vehicle(tractor–semitrailer–dolly–semitrailer) using active steering front axle dolly. Both and syntheses are performed via Linear Matrix Inequality (LMI) optimisation. From a practical point view, controller simple ea...

Future active safety systems need more accurate information about the state of vehicles. This article proposes a method to evaluate the lateral state of a vehicle based on measured tyre forces. The tyre forces of two tyres are estimated from optically measured tyre carcass deflections and transmitted wirelessly to the vehicle body. The two remaining tyres are so-called virtual tyre sensors, the...

A nonlinear model consisting “yaw, roll, longitudinal, lateral and pitch” has been developed in which, tire and suspension characteristics have been considered. Tire model is based on the elliptic concept and tire Calspan data. According to this tire model, cornering force and aligning moment are computed as a function of slip and camber (inclination) angles, normal load, tire adhesion characte...

This paper presents a sensor which can be included in an Advanced Driver Assistance System (ADAS) that is compliant with the Vehicle to Infrastructure communication standard (V2I). This system allows estimation of the vehicle lateral position in real time by ensuring cooperation between an on-board vehicle system and passive transponders integrated in the lateral white strips of the road. Based...
