Palffy, A. (author)This thesis addresses the problem of object detection with automotive radar sensors in the field of intelligent vehicles with special attention to vulnerable road users: pedestrians, cyclists, and motorcyclists. It is not the goal of this work to improve the hardware design or signal processing algorithms of the radar sensors themselves, but to...doctoral thesis 2022

Braun, M. (author)This thesis addresses the topic of visual person detection and pose estimation. While these tasks are relevant for a broad range of applications, this thesis focuses on the domain of intelligent vehicles in urban traffic scenes. This domain is particularly interesting due to specific challenges related to visual perception from a moving vehicle....doctoral thesis 2022

Hehn, T.M. (author)that do not require any action from the drivers for a short period of time. Although these systems are still limited and only reliable in certain situations, it shows the general trend: cars will become more and more autonomous. The reasons why people and companies are eagerly anticipating fully autonomous cars are manifold: self-driving...doctoral thesis 2022

Beekes, Sebastiaan (author)Testing Sidewalk Autonomous Delivery Robot (SADR) performance in real world conditions is important to prove whether the innovation is ready for large-scale adoption. Currently, testing SADRs in public is not allowed in the Netherlands, because little is known about the actual risks associated with delivery robots, and the risks are currently...master thesis 2022

Wagih, Hassan (author), Osman, M.E.A. (author), Awad, Mohammed I. (author), Hammad, Sherif (author)In this paper, an approach for reducing the drift in monocular visual odometry algorithms is proposed based on a feedforward neural network. A visual odometry algorithm computes the incremental motion of the vehicle between the successive camera frames, then integrates these increments to determine the pose of the vehicle. The proposed neural...conference paper 2022

Wang, X. (author), Li, Z. (author), Alonso Mora, J. (author), Wang, M. (author)Real-time safety systems are crucial components of intelligent vehicles. This paper introduces a prediction-based collision risk assessment approach on highways. Given a point mass vehicle dynamics system, a stochastic forward reachable set considering two-dimensional motion with vehicle state probability distributions is firstly established. We...conference paper 2022

Bertipaglia, A. (author), Shyrokau, B. (author), Alirezaei, Mohsen (author), Happee, R. (author)This paper presents a novel methodology to auto-tune an Unscented Kalman Filter (UKF). It involves using a Two-Stage Bayesian Optimisation (TSBO), based on a t-Student Process to optimise the process noise parameters of a UKF for vehicle sideslip angle estimation. Our method minimises performance metrics, given by the average sum of the states’...conference paper 2022

Zheng, Y. (author), Shyrokau, B. (author), Keviczky, T. (author)Motion comfort is the basis of many societal benefits promised by automated driving and motion planning is primarily responsible for this. By planning the spatial trajectory and the velocity profile, motion planners can significantly enhance motion comfort, ideally without sacrificing time efficiency. Active suspensions can push the boundary...conference paper 2022

Roth, M. (author), Stapel, J.C.J. (author), Happee, R. (author), Gavrila, D. (author)We present a novel method for vehicle-pedestrian path prediction that takes into account the awareness of the driver and the pedestrian towards each other. The method jointly models the paths of vehicle and pedestrian within a single Dynamic Bayesian Network (DBN). In this DBN, sub-graphs model the environment and entity-specific context cues...journal article 2022

Marcelis, N.H.H. (author)With the performance of current motion planning methods being highly dependent on the quality of the perception system, robust 3D multi-object detection and tracking are vital for autonomous driving applications. Despite all the advancements in 2D and 3D object detectors, robust tracking of pedestrians in dense scenarios is still a challenging...master thesis 2021

Hoogmoed, Jim (author)The level of automation in vehicles is growing. But until all vehicles are completely automated, there will be a transition period where automated vehicles and human drivers coexist. Because these road users will coexist, it is necessary that automated vehicles understand human drivers and vice versa. This study aims to create a model that...master thesis 2021
