Vehicle Dynamics Modelling: Lateral and Longitudinal

2021 8th International Conference on Signal Processing and Integrated Networks (SPIN), 2021
The design of vehicle control systems requires sufficiently accurate vehicle dynamics modelling to validate a desired closed-loop performance of the system in offline mode prior to real time testing. The implication of lateral and longitudinal dynamics in the vehicle plant model plays a pivotal role in determining the enhanced performance and response ...

Control Design for Vehicle's Lateral Dynamics

2006 IEEE International Conference on Systems, Man and Cybernetics, 2006
issues of controllability and stabilization design for vehicle's lateral dynamics are presented. Based on the assumption of constant driving speed, a second-order nonlinear lateral dynamical model is obtained. It is observed that saddle node bifurcation will appear in vehicle dynamics with respect to the variation of the front wheel steering angle ...

Actuator Fault Detection for Vehicle Lateral Dynamics

2018 5th International Conference on Control, Decision and Information Technologies (CoDIT), 2018
This paper proposes an actuator fault detection based on unknown input observer for simultaneously state estimation and fault estimation applied to lateral vehicle dynamics. The lateral dynamics is modeled by a linear parameter varying model where the longitudinal velocity is considered as parameter varying.

Robust fault detection for vehicle lateral dynamics

2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012
This paper investigates the problem of fault detection and isolation (FDI) for vehicle lateral dynamics. The system under consideration is a Linear Parameter Varying (LPV) model, where the scheduling parameter is related to the vehicle speed. The heart of the proposed approach relies in synthesizing robust residuals for some specified working speed ...

Detection of critical situations for vehicle lateral dynamics

2014 American Control Conference, 2014
This paper presents a new methodology for the detection of critical situations for vehicle lateral dynamics, in order to improve the ESP systems. The principle of the approach rests on the modeling of the vehicle thanks to a bicycle model. The lateral tire forces are well known to be highly non-linear. However, in normal driving region, those force can

Fault Tolerant Estimation of Vehicle Lateral Dynamics

IFAC Proceedings Volumes, 2003
Abstract In this paper model based fault tolerant estimation of vehicle lateral dynamics is studied. The core of the study is the development of an adaptive observer that is used for the estimation purpose in the fault-free situation. To be tolerant to possible sensor faults, different observers/estimator are then proposed, which deliver an ...

Fault detection for lateral and vertical vehicle dynamics

Control Engineering Practice, 2004
Abstract Mechatronic systems for vehicles have received increased importance for improving automotive safety and comfort. These systems are designed to aid the driver by preventing unstable or unpredictable vehicle behavior and to stabilize the horizontal and vertical motion of the vehicle.

Basics of Lateral Vehicle Dynamics

2016
This chapter is an introduction to lateral vehicle dynamics and steady and dynamic cornering . Basic discussions will serve to analyse the essential factors influencing the lateral vehicle dynamics of a car and the steering wheel angle and torque indicated by the driver. Models are required for a more detailed analysis, they expand upon the fundamental

Approaches to Estimation of Vehicle Lateral Dynamics

2019 International Conference on Advanced Mechatronic Systems (ICAMechS), 2019
In this paper, two new sliding mode state observers are developed for the lateral dynamics of road vehicles. It is shown that the observability of a general class of second-order linear time-varying systems (LTVSs) is investigated, the sliding observers for the LTVSs with both the known-input and the unknown-input are then proposed.

Linear analysis of lateral vehicle dynamics

2017 21st International Conference on Process Control (PC), 2017
Systematic analysis of lateral dynamics of a ground vehicle (e.g. passenger car) is presented in this paper. The results are based on the simplest possible single-track model. Effects of variations in the physical parameters — mass, the moment of inertia, tire priorities, vehicle geometry — on the response times, damping ratios, natural frequencies and
