Decision making for autonomous vehicles: Combining safety and optimality

In this paper, we propose a novel decision maker design for an autonomous vehicle driving on a highway, considering safety and optimality, and which is scalable, i.e., remains computationally tractable for more complex situations. This is realized in two stages. First, all safe actions are found, and second, from these actions the optimal action...

Incorporating car owner preferences for the introduction of economic incentives for speed limit enforcement

Human error including driving misbehavior contributes to over 90 percent of road vehicle accidents, and speeding is considered to be risky. Smart technologies, such as Connected Vehicle System (CVS) are among the interesting technical options to improve driving behavior, and Pay-As-You-Speed (PAYS) is an effective economic incentive to reduce...

A Spatial Approach to Control of Platooning Vehicles: Separating Path-Following from Tracking

We introduce a new way to look at the combined lateral and longitudinal control problem for platooning vehicles by studying these problems separately. The lateral control problem is approached as a path following problem in the spatial domain: based on the path of the preceding vehicle we determine a path for the following vehicle which...

Improvement of Network Performance by In-Vehicle Routing Using Floating Car Data

This paper describes a study which gives insight into the size of improvement that is possible with individual in-car routing advice based on the actual traffic situation derived from floating car data (FCD). It also gives an idea about the required penetration rate of floating car data needed to achieve a certain degree of improvement. The...

Security challenges for cooperative and interconnected mobility systems

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...

Integration of different simulation tools for the development of next generation Automotive Safety Systems

The development of intelligent in-car systems and connected vehicle systems is of major concern to the automotive industry. These systems need to function properly in a vast amount of different traffic scenarios, which involves interaction with other traffic actors, both human and technical, in a large area around the vehicle. This poses a...

Development and application of an integrated evaluation framework for preventive safety applications

Preventive safety functions help drivers avoid or mitigate accidents. No quantitative methods have been available to evaluate the safety impact of these systems. This paper describes a framework for the assessment of preventive and active safety functions, which integrates procedures for technical performance, human factors, and safety...

A simulation environment for developing intelligent headlight systems

This paper presents a simulation environment for developing Intelligent Headlight Systems (IHS). These are systems that actively adapt the headlights based on events in the traffic environment such as curves, oncoming vehicles and pedestrians. The results of applying the simulation environment to two IHS research projects of an OEM are presented...

Simulating Cooperative Vehicle-to-Infrastructure Systems: A Multi-Aspect Assessment Tool Suite

Modelling cooperative roadside and in-vehicle intelligent transport systems using the its modeller

Within the coming years, the developments of infrastructural and in-vehicle ITS systems will come together and result in the development of cooperative vehicle-infrastructure ITS systems. The development of these integrated cooperative systems will require new modelling tools that allow a detailed modelling of both the roadside and the in...

Accelerating cooperative systems' development through the Grand Cooperative Driving challenge

Cooperative driving systems comprise an important research area. They are considered a promising solution for reducing traffic congestion, reducing environmental impact and improving traffic safety and driver comfort. The key to these systems is the communication and interaction between vehicles and between vehicles and road side infrastructure....

Scalable HIL simulator with mixed real and virtual sensing capabilities

The advance in Intelligent Vehicle Systems (IVS) puts emphasis to vehicle-vehicle and vehicle-environment interactions. Sensing and sensory data interpretation play ever increasing role because sensing becomes the primary way of collecting information about the environment. In the IVS application domain the environment is unstructured, which...

Vibrotactile in-vehicle navigation system

A vibrotactile display, consisting ofeight vibrating elements or tactors mounted in a driver's seat, was tested in a driving simulator. Participants drove with visual, tactile and multimodal navigation displays through a built-up area. Workload and the reaction time to navigation messages were measured for normal and high workload conditions....

A runtime framework for system safety

With the increasing complerity of in-vehicle systems and the new generation of communication based (mission critical) applications the sue of the state space increases with unmanageable pace. Even when all design-time procedures to guarantee safety are followed adequotely, in run-time there irrevocable.remain unforeseen and untested system...
