Highways tend to get congested because of the increase in the number of cars travelling on them. There are two solutions to this. The first one, which is also expensive, consists in building new highways to support the traffic. A much cheaper alternative consists in the introduction of advanced ITC software control systems to support the traffic and increase the efficiency of the already existing...
The dynamics of multi-agent in nature have been largely studied for a long time to investigate how the aggregation of agents can move smoothly in complex environments without collision. The main insights can be summarized such that the aggregated dynamics of animals and particles can be explained by an individual's simple rules. In a similar vein, we conjecture that such simple rules for vehicle maneuvering...
This paper presents a full chain to detect and photograph impacts from the infrastructure. This work is the result of the collaborative project InfraCall. It focuses on the protection of the crash cushions and barrier rails. The principle is to adapt on them sensors and to take a photo. The informations are instantly transmitted to an emergency call center. After having described the system, we present...
Collision Warning Systems (CWS) are safety systems designed to warn the driver about an imminent collision. A CWS monitors the dynamic state of the traffic in realtime by processing information from various proprioceptive and exteroceptive sensors. It assesses the potential threat level and decides whether a warning should be issued to the driver through auditory and/or visual signals. Several measures...
Driver assistance systems are commonly available in many vehicles. There are systems for safety functions like the Electronic Stability Control, Automatic Traction Control, Anti-lock Brake System and automatic emergency braking. There are also systems for comfort functions like adaptive cruise control with stop and go functionality and combined safety and comfort functions like lane keeping and side-wind...
Development and integration of physiological sensors into automotive applications is gaining importance. Assistance systems which possess knowledge about the driver's cognitive state could increase road safety. In this paper we present a flexible framework that enables the development, evaluation and verification of sensors and algorithms for automotive applications using physiological signals under...
Many dynamic simulators have been developed in the last thirty years for different types of vehicles. Flight simulators and drive simulators are very well known examples. This paper describes the design and implementation of a dynamic simulator for the testing of inertial sensors devoted to vehicle navigation through a Hardware-In-The-Loop test rig composed of an industrial robot and a commercially...
In a near future, vehicles will be provided with a variety of new sensors capable of gathering information from their surroundings. These vehicles will also be capable of sharing the harvested information via Vehicular Ad hoc NETworks (VANETs) with nearby vehicles, or with the emergency services in case of an accident. Hence, distributed applications based on VANETs will need to agree on a ‘common...
External airbag installed in vehicle can protect pedestrians and reduce injuries in the event of a crash. In this paper, a collision prediction system for external airbag using an interacting multiple model is proposed to detect a collision and inflates quickly enough to cushion the impact. The system includes two different models, constant velocity and constant acceleration, in order to estimate...
This paper investigates control design for the platoon of automated vehicles whose sensors have limited sensing capability. A novel hybrid platoon model is established, in which actuator delay (e.g., the fueling and braking delay) and the effect of sensing range limitation are involved. Based on the new model, a framework of guaranteed-cost controller design is presented, which can robustly stabilize...
This paper mainly describes the vehicle traveling data recorder system based On ARM. It selects the huge flash rom memory as the memorizer. It collects and stores the real-time data every second by timer interrupt, and uses µC/OS-¢ò, an embedded operating system, to design the software. Computer can communicate with microchip by com interrupt and store the data in the hard disk by binary system.
Influenced by the Parnas and Madey's four-variable model and the concept of phenomena in problem frames, we desire to provide guidelines to facilitate refinement-based formal modelling. These guidelines are based on monitored, controlled, mode and commanded (MCMC) phenomena of a control system. Commanded phenomena reflect the role that an operator plays in system control. The mode phenomenon captures...
Driver support systems aim to support or take over part of the driving task in order to drive vehicles in a safe, comfortable and efficient way. To this end, in literature, different controller designs have been put forward over the past two decades. This paper proposes an optimal control framework to model driver support systems. In this approach, the acceleration of vehicles in a platoon following...
This paper presents an investigation of a research project titled “Innovative Seating Systems” by BMW Group “Research and Technology” Team. It is based on my idea and reports about “Benefits of using Bionic Seats in Roadster cars” which is submitted and accepted by BMW Group Co-Creation Lab in March 2010. In this paper, three BMW Group revolutionary innovative seating systems, Bionic Seat, Ergo Seat...
A major problem in the handling of high speed performance vehicles is the rolling of the vehicle. While pushing the car to the limit sometimes the less experienced drivers tip it over the safe speed line and rolling of the car takes place. It leads to a number of accidents and thus in order to reduce the rolling effect we have come up with the innovation of Roll Sensing Control Unit(RSCU). The RSCU...
Latest generation of vehicle tracking devices relies not only on Global Positioning System (GPS) but also uses a low-cost Micro-Electro-Mechanical Systems (MEMS) accelerometers. This combination supports new services as driving style characterization and Automatic Crash Notification (ACN). Focus will be on practical considerations of such telematics unit. Work will consider boundaries of allowed errors...
The new communication technologies integrated into the automotive sector offer an opportunity for better assistance to people injured in traffic accidents, reducing the response time of emergency services, and increasing the information they have about the incident. Determining more accurately the human and material resources required for each particular accident could significantly reduce the number...
This paper reports the development and in-water experimental evaluation of two new methods for the problem of in-situ calibration of the alignment rotation matrix between Doppler sonar velocity sensors and gyrocompass attitude sensors arising in the navigation of underwater vehicles. Most previously reported solutions to this alignment calibration problem require the use of absolute navigation fixes...
Emergency maneuvering systems can take control of a vehicle in high-risk situations caused by distracted, fatigued, or careless drivers, which can reduce the frequency and severity of collisions. But in order to override the user's control the vehicle must reason with uncertain information: sensing provides noisy and partial input, vehicle dynamics models are never perfectly calibrated, and other...
We consider an anchor-free source-localization problem relevant to the control of fast moving vehicles, approaching a stop located indoors (stations, tunnels, warehouses, etc). A peculiarity of the problem is that both the location of fixed devices (access points) and the trajectory of the target (vehicle) are unknown. Two time-difference-of-arrival (TDOA)-based weighted least-squares (WLS) methods...
