Despite all the different technological innovations and advances in the automotive field, autonomous vehicles are still in the testing phase. Many actors are working on several improvements in many domains to make autonomous cars the safest option. One of the important dimensions is cybersecurity. Autonomous vehicles will be prone to cyberattacks, and criminals might be motivated to hack into the vehicles' operating systems, steal essential passenger data, or disrupt its operation and jeopardize the passenger's safety. Thus, cybersecurity remains one of the biggest obstacles to overcome to ensure vehicles safety and the contribution that this technology can bring to society. Indeed, the actual and future design and implementation of Autonomous Vehicles imply many communication interfaces, In-vehicle communication of the embedded system, Vehicle-to-X (V2X) communications between the vehicle and other connected vehicles and structures on the roads. Even though the cybersecurity aspect is incorporated by design, meaning that the system needs to satisfy security standards (anti-virus, firewall, etc.), we cannot ensure that all possible breaches are covered. The Intrusion Detection System (IDS) has been introduced in the IT world to assess the state of the network and detect if a violation occurs. Many experiences and the history of IT have inspired the cybersecurity for autonomous vehicles. Nevertheless, autonomous vehicles exhibit their own needs and constraints. The current state of vehicles evolution has been made possible through successive innovations in many industrial and research fields. Artificial Intelligence (AI) is one of them. It enables learning and implementing the most fundamental self-driving tasks. This thesis aims to develop an intelligent invehicle Intrusion detection system (IDS) using machine learning (ml) from an automotive perspective, to assess and evaluate the impact of machine learning on enhancing the security of future vehicle intrusion detection system that fits in-vehicle computational constraints. Future In-vehicle network architecture is composed of different subsystems formed of other ECUs (Electronic Controller Units). Each subsystem is vehicles. Our primary focus is on In-vehicle communication security. We conduct an empirical investigation to determine the underlying needs and constraints that in-vehicle systems require. First, we review the deep learning literature for anomaly detection and studies on autonomous vehicle intrusion detection systems using deep learning. We notice many works on in-vehicle intrusion detection systems, but not all of them consider the constraints of autonomous vehicle systems. We conduct an empirical investigation to determine the underlying needs and constraints that in-vehicle systems require. We review the deep learning literature for anomaly detection, and there is a lack of tailored study on autonomous vehicle intrusion detection systems using Deep Learning (DL). In such applications, the data is unbalanced: the rate of normal examples is much higher than the anomalous examples. The emergence of generative adversarial networks (GANs) has recently brought new algorithms for anomaly detection. We develop an adversarial approach for anomaly detection based on an Encoding adversarial network (EAN). Considering the behaviour and the lightweight nature of in-vehicle networks, we show that EAN remains robust to the increase of normal examples modalities, and only a sub-part of the neural network is used for the detection phase. Controller Area Network (CAN) is one of the mostused vehicle bus standards designed to allow microcontrollers and devices to communicate. We propose a Deep CAN intrusion detection system framework. We introduce a Multi-Variate Time Series representation for asynchronous CAN data. We show that this representation enhances the temporal modelling of deep learning architectures for anomaly detection

Cooperative Intelligent Transport Systems (C-ITS) is an upcoming technology that will change our driving experience in the near future. In such systems, vehicles cooperate by exchanging Vehicle-to-X communication (V2X) messages over the vehicular network. Safety applications use the data in these messages to detect and avoid dangerous situations on time. Therefore, it is crucial that the data in V2X messages is secure and accurate.In the current C-ITS system, the messages are signed with digital keys to ensure authenticity. However, authentication does not ensure the correctness of the data. A genuine vehicle could have a faulty sensor and therefore send inaccurate information. An attacker could also obtain legitimate keys by hacking into the on-board unit of his vehicle and therefore transmit signed malicious messages.Misbehavior Detection in C-ITS is an active research topic aimed at ensuring the correctness of the exchanged V2X messages. It consists of monitoring data semantics of the exchanged messages to detect and identify potential misbehaving entities. The detection process is divided into multiple steps. Local detection consists of first performing plausibility and consistency checks on the received V2X messages. The results of these checks are then fused using a local detection application. The application is able to identify various V2X anomalies. If an anomaly is detected, the vehicle will collect the needed evidence and create a misbehavior report. This report is then sent to a cloud based misbehavior authority.This authority has a goal of ensuring the correct operation of the C-ITS system and mitigating the effects of attacks. It will first collect the misbehavior reports from vehicles and would then investigate the event and decide on the suitable reaction.In this thesis, we evaluate and contribute to the local, reporting and global steps of the misbehavior detection process

In the past our cars were moving. In the future, they will converse through V2V communication (Vehicle to Vehicle): the cars exchange data such as position and speed. The onboard computer can also record information from the car - rain sensors, brightness, but also ESP, ABS -, and give birth to an information network where that information is collected by an infrastructure able to analyse it. This is the V2I communication (Vehicle to Infrastructure). The greater the number of vehicles that detect information - such as the presence of fog-, the higher the probability of fog, and the faster the infrastructure can inform drivers approaching the area where is the fog. In this context, we are interested in onboard risky condition estimation caused by climatic factors. Climate can create conditions of hazards such as snow, Rain, fog. . . These conditions change pavement conditions and the sight offered to the driverGiven that there is no sensor reflecting the road conditions which can be used on vehicles with standard sensors, we present in the first part of the thesis a new maximum road’s friction estimator. In addition, there are already some visibility distance estimators that use an onboard camera, but they have some limitations that we tried to circumvent. The presentation of this estimator constitutes the second part of the thesis
De, Miranda Neto Arthur. "Embedded visual perception system applied to safe navigation of vehicles." Compiègne, 2011. http://www.theses.fr/2011COMP1987.
This thesis addresses the problem of obstacle avoidance for semi- and autonomous terrestrial platforms in dynamic and unknown environments. Based on monocular vision, it proposes a set of tools that continuously monitors the way forward, proving appropriate road informations in real time. A horizon finding algorithm was developed to sky removal. This algorithm generates the region of interest from a dynamic threshold search method, allowing to dynamically investigate only a small portion of the image ahead of the vehicle, in order to road and obstacle detection. A free-navigable area is therefore represented from a multimodal 2D drivability road image. This multimodal result enables that a level of safety can be selected according to the environment and operational context. In order to reduce processing time, this thesis also proposes an automatic image discarding criteria. Taking into account the temporal coherence between consecutive frames, a new Dynamic Power Management methodology is proposed and applied to a robotic visual machine perception, which included a new environment observer method to optimize energy consumption used by a visual machine. This proposal was tested in different types of image texture (road surfaces), which includes free-area detection, reactive navigation and time-to-collision estimation. A remarkable characteristic of these methodologies is its independence of the image acquiring system and of the robot itself. This real-time perception system has been evaluated from different test-banks and also from real data obtained by two intelligent platforms. In semi-autonomous tasks, tests were conducted at speeds above 100 Km/h. Autonomous displacements were also carried out successfully. The algorithms presented here showed an interesting robustness

In this dissertation, we present our research work held at the Center of Robotics (CAOR) of the Ecole des Mines de Paris which tackles the problem of intelligent video analysis. The primary objective of our research is to prototype a generic framework for intelligent video analysis. We optimized this framework and configured it to cope with specific application requirements. We consider a people tracker application extracted from the PUVAME project. This application aims to improve people security in urban zones near to bus stations. Then, we have improved the generic framework for video analysis mainly for background subtraction and visual object detection. We have developed a library for machine learning specialized in boosting for visual object detection called LibAdaBoost. To the best of our knowledge LibAdaBoost is the first library in its kind. We make LibAdaBoost available for the machine learning community under the LGPL license. Finally we wanted to adapt the visual object detection algorithm based on boosting so that it could run on the graphics hardware. To the best of our knowledge we were the first to implement visual object detection with sliding technique on the graphics hardware. The results were promising and the prototype performed three to nine times better than the CPU. The framework was successfully implemented and integrated to the RTMaps environment. It was evaluated at the final session of the project PUVAME and demonstrated its fiability over various test scenarios elaborated specifically for the PUVAME project
