Article
This paper presents automatic parallel parking for a passenger vehicle, with highlights on a path-planning method and on experimental results. The path-planning method consists of two parts. First, the kinematic model of the vehicle, with corresponding geometry, is used to create a path to park the vehicle in one or more maneuvers if the spot is ve...
Conference Paper
This paper compares 3 ASR1 control laws, a PI controller, a linearizing feedback and a flatness based control. First, the controllers are designed based on a two state equations vehicle model. Then, the controllers are experimentally validated on an hybrid vehicle (VELROUE) with rear electric wheels and front axle ICE2 traction. Finally, the nonlin...
Conference Paper
This paper deals with path planning for car-like vehicle in parallel parking problems. Our path planning method uses simple geometry of the vehicle kinematic model. The presented strategy consists in two parts: create a simple geometric path for the parallel parking in one or more maneuvers, formed by circle arcs and then transform it to a continuo...
Article
Adaptive control of nonlinearly parameterized (NLP) systems is an unknown field, where few results have been proposed up to now. In this paper, we propose a new adaptive control algorithm for systems with multilinear parameterization. Differently from our previous work where the two parameters case was considered, we treat here the general case of...
Conference Paper
The driver active assistances have gained recently in importance and become usual features in commercialized vehicles. Nevertheless, the sharing of the vehicle control with the driver, especially for the steering assistances, is an open issue. The rear wheels steering could be an answer to this question. This study contains the development of a con...

The paper discusses the problem of lane departure avoidance for a vehicle. A corrective mech-anism imposes its control action whenever the vehicle is no longer inside a nominal region centered along the middle of the lane. Set theoretic methods are used in order to design this control action and to guarantee global stability. Additionally, for the...

Single-vehicle road departure accidents represent a substantial amount of today's accidents. This paper presents the design and experimental test of an active steering assistance system that offers two functions: lane departure avoidance by temporary activation and maintaining vehicle heading by permanent activation. Each of the two functions can b...
Article
This paper proposes a combined vehicle assistance system for lane keeping, lane departure avoidance and yaw stability. The system uses a double actuation: steering and differential braking. The linear feedback control laws with additional feedforward gains for these actuators result from a BMI optimization problem minimizing the reachability set of...
Conference Paper
This paper presents the design and the simulation test of a Takagi-Sugeno (TS) fuzzy lane keeping output feedback controller. The vehicle control law has been developed based on invariant sets and quadratic boundedness theory, based on a common quadratic function. The TS fuzzy model is able to handle elegantly the nonlinear behavior the vehicle lat...
Conference Paper
This paper presents the design and the simulation test of a Takagi-Sugeno (TS) fuzzy output feedback for yaw motion control. An integrated steering and differential braking controller based on invariant sets, quadratic boundedness theory and a common Lyapunov function has been developed. The TS fuzzy model is able to handle elegantly the nonlinear...
Article
Lane departure avoidance systems assist actively the driver during inattention or drowsiness and increase driving safety. Most of the lane departure avoidance systems use for the lateral control of the vehicle in closed loop a DC motor similar to the electrical powered steering (EPS) assistance. Important difficulties and limits of this approach ar...
Article
This paper presents the design and the practical implementation of vehicle steering assistance that helps the driver avoid unintended lane departure. A switching strategy is built to govern the driver-assistance interaction, and the resulting hybrid system is formalized as an input/output (I/O) hybrid automaton. Composite Lyapunov functions, polyhe...
Article
This paper addresses robust H∞ static output feedback control problem for multimodel systems with time-varying normbounded uncertainties. Sufficient conditions for synthesis of a static output feedback controller are derived in terms of a set of linear matrix inequalities (LMIs). The effectiveness of the proposed design method is demonstrated by an...
Article
This paper presents the design and the simulation test of an assistance system that helps the driver to perform vehicle following maneuver. When activated, the assistance drives the vehicle to the desired inter-distance. A switching strategy governs the driver-assistance interaction. The vehicle following control law has been developed based on inv...
Conference Paper
This paper proposes an active steering assistance system that could act as lane departure avoidance and lane keeping system. The assistance has been designed initially for a lane departure avoidance purpose. In this paper the driver-assistance interaction is studied with the objective to allow a permanent system activation and hence a lane keeping...
Article
This paper presents a steering assistance system that prevents unintended lane departures. The assistance intervenes only when the driver is inattentive and the vehicle is about to leave the lane. Road curvatures represent a challenge for the control law concerning the lane keeping performance as well as the lane overshoot in the case of activation...
Article
In this paper, a steering assistance system is designed and experimentally tested on a prototype passenger vehicle. Its main goal is to avoid lane departures when the driver has a lapse of attention. Based on a concept linking Lyapunov theory with Linear Matrix Inequalities (LMI) optimization, the following important features are ensured during the...

Les caractéristiques de cette assistance se déclinent ainsi : - intervention dans les moments d'inactivité du conducteur alors que la sortie de voie devient imminente et rétablissem...
Article
One of the most frequent causes of highway accidents is the unintended out of lane deviation, due to moments of inattention, sleepiness or drowsiness. The enclosed video shows a driver steering assistance that prevents this type of lane departure. For vehicles with conventional steering columns, there are some difficulties in carrying out this type...

This paper presents a vehicle steering assistance designed to avoid lane departure during driver inattention periods. Activated for a driver loss of concentration during a lane keeping maneuver the steering assistance drives the vehicle back to the center of the lane. In order to ensure a vehicle trajectory as close as possible to the centerline, t...
Conference Paper
We present in this contribution the design and implementation of a steering assistance control. The main goal is to avoid the lane departure in case the driver loses attention. This control has been developed to keep the vehicle's trajectory within certain bounds during the assistance intervention, while maintaining a limited torque control input....
Conference Paper
In this paper we present a vehicle steering assistance to avoid lane departure during driver inattention. A switching control strategy and a linear state feedback control have been developed to this end. Lyapunov and LMI methods have been used to optimize the control, confining its transient response during the assistance activation.
Conference Paper
A control for vehicle steering assistance has been developed in this paper to help the driver keep the lane during inattention periods. Activated by the front wheels exceeding a predefined central lane strip, the control guarantees to maintain the vehicle within an extended strip in the middle of the lane. Moreover, the assistance torque and the va...

Since unification, the debate about Germany's poor economic performance has focused on supply-side weaknesses, and the associated reform agenda sought to make low-skill labour markets more flexible. We question this diagnosis using three lines of argument. First, effective restructuring of the supply side in the core advanced industries was carried...
