Most of the common road accidents are due to the driver’s inappropriate behavior, lack of attention, tiredness, and road conditions which usually cause the vehicle to deviate from the roadway or crash into others. Although, thanks to the Steer-by-Wire system, recent research showed that is now possible to enhance vehicles’ manipulability and users’ safety by stimulating the drivers to react efficiently in common and critical situations. This paper describes a new strategy to assist the driver in his trajectories’ planning on a multiple-lane highway. A driving assistant is here designed to give appropriate and continuous tactile feedbacks generated from a virtual force field present in the roadway’s environment. First, the assistant algorithm global structure is presented. Then, a road condition dependant virtual force field based driving input is designed in order to avoid road deviations as well as to enhance safety in presence of potentially dangerous road conditions, as lack of adherence and visibility. The performance of the system is evaluated firstly through preliminary simulations, and then confirmed on a driving simulator.

Inherent Part

The concept of electric vehicle as a fully automated mobile robot – a.k.a. X-by-Wire, or Drive-by-Wire (DbW) concepts – is becoming more and more attractive in the modern automotive industry. This idea is based on replacing a mechanical subsystem by its electronic equivalent, which includes sensors and actuators, with a computer in-between. Three of the components, namely Throttle-by-Wire, Brake-by-Wire, and Steer-by-Wire, are the most complex and risky elements of the X-by-Wire technology. Moreover, these elements constitute the inherent part of the general DbW paradigm. This paper reports work-in-progress on the design and prototyping of a scaled-down 1 : 6 proof-of-concept model of a commercial vehicle with an integrated X-by-Wire system. The control for its components is discussed, while emphasizing the Steer-by-Wire actuator based on the Ackermann condition. The influence of heading velocity and turning angle on the slipping angle and path error of the model is discussed. The performance of the dynamics of the prototype is assessed over prescribed paths; deviations from the no-slip condition are evaluated.

Wire System

This paper presents the development process of a robust and ROS-based Drive-By-Wire system designed for an autonomous electric vehicle from scratch over an open source chassis. A revision of the vehicle characteristics and the different modules of our navigation architecture is carried out to put in context our Drive-by-Wire system. The system is composed of a Steer-By-Wire module and a Throttle-By-Wire module that allow driving the vehicle by using some commands of lineal speed and curvature, which are sent through a local network from the control unit of the vehicle. Additionally, a Manual/Automatic switching system has been implemented, which allows the driver to activate the autonomous driving and safely taking control of the vehicle at any time. Finally, some validation tests were performed for our Drive-By-Wire system, as a part of our whole autonomous navigation architecture, showing the good working of our proposal. The results prove that the Drive-By-Wire system has the behaviour and necessary requirements to automate an electric vehicle. In addition, after 812 h of testing, it was proven that it is a robust Drive-By-Wire system, with high reliability. The developed system is the basis for the validation and implementation of new autonomous navigation techniques developed within the group in a real vehicle.
