van Nunen, E. (author), Verhaegh, J. (author), Silvas, E. (author), Semsar-Kazerooni, E. (author), van de Wouw, N. (author)To improve traffic throughput, Cooperative Adaptive Cruise Control (CACC) has been proposed as a solution. The usage of Vehicle-to-Vehicle (V2V) communication enables short following distances, thereby increasing road capacity and fuel reduction (especially for trucks). Control designs for CACC use the wirelessly communicated intended...conference paper 2018

(author)Cooperative adaptive cruise control and platooning are well-known applications in the field of cooperative automated driving. However, extension toward maneuvering is desired to accommodate common highway maneuvers, such as merging, and to enable urban applications. To this end, a layered control architecture is adopted. In this architecture,...article 2017

Verhaegh, J. (author), Ploeg, J. (author), van Nunen, E. (author), Teerhuis, A. (author)This paper presents a method for trajectory control, based on feedback linearization to guide an Automatic Guided Vehicle (AGV). The novelty of this work, is the adaptation of a reference trajectory with respect to a desired velocity in real-time to avoid collisions using a time-scaling mechanism. Employing this mechanism, collision avoidance by...conference paper 2017

van Nunen, E. (author), Esposto, F. (author), Saberi, A.K. (author), Paardekooper, J.P. (author)This paper addresses safety indicators for truck platooning at short inter-vehicle distances (with a time gap of 0.5 s). The aim of a safety indicator is to determine the correct moment for initiating a Collision Avoidance brake action to prevent a collision with the preceding truck in threatening situations. Three safety indicators are selected...conference paper 2017

van Nunen, E. (author), Tzempetzis, D. (author), Koudijs, G. (author), Nijmeijer, H. (author), van den Brand, M. (author)Platooning has shown to be technically feasible, but safety aspects are still challenging. Wireless communication between vehicles allows to maintain reduced inter-vehicle distances, thereby improving traffic throughput and decreasing fuel consumption. As the driver can no longer be a backup at short inter-vehicle distances, the system needs to...conference paper 2016

van Willigen, W.H. (author), Kester, L.J.H.M. (author), van Nunen, E. (author), Haasdijk, E. (author)This article proposes a safety check extension to Adaptive Cruise Control systems where the critical headway time is estimated in real-time. This critical headway time estimate enables automated reaction to crisis circumstances such as when a preceding vehicle performs an emergency brake. We introduce a method for critical headway approximation...article 2015

(author)Structural interaction has been one of the critical issues for improved frontal impact protection. An evaluation procedure for structural interaction has been difficult to develop using objective test data procedures. While previous research with the PDB barrier has been promising based on subjective evaluations, an objective assessment criteria...conference paper 2013

(author)Software is becoming an important part of the innovation for vehicles. In addition, the systems in vehicles become interconnected and also get external connections, to the internet and Vehicular Ad hoc NETworks (VANETs). These trends form a combined security and safety threat, because recent research has demonstrated a large number of security...conference paper 2013

van Nunen, E. (author), van den Broek, T.H.A. (author), van Wolferen, J. (author)In this paper, a collision warning application is described. The collision warning application is in particular useful when the driver’s view is blocked due to a large vehicle. The risk estimation algorithm, which is originally designed and validated in scenarios with vulnerable road users, is here applied in a non-line-of-sight scenario with...conference paper 2011

Ploeg, J. (author), Scheepers, B.T.M. (author), van Nunen, E. (author), van de Wouw, N. (author), Nijmeijer, H. (author)Road throughput can be increased by driving at small inter-vehicle time gaps. The amplification of velocity disturbances in upstream direction, however, poses limitations to the minimum feasible time gap. String-stable behavior is thus considered an essential requirement for the design of automatic distance control systems, which are needed to...conference paper 2011
