In order to develop the bottom driver software more rapidly and efficiently which are used in automotive battery management system and to get rid of high dependence on the hardware and low reusability of the drivers in automobile controller, this paper puts forward a kind of driver design method based on automotive open system architecture (AUTOSAR). Simulation modeling module has been made with the...
This paper proposes a method for a real-time classification of the absolute driving style using three levels of sportiveness: calm, normal and sporty. The algorithm is based on a physical gg-plot-based approach and on a novel manouvre detection algorithm. The method makes use of standard vehicle signals which can be also provided by an external IMU+GPS system. Experimental results show the effectiveness...
Since many motor companies are considering applying gesture control to in-vehicle interaction, it becomes a question that how to match the secondary driving task with a suitable gesture. Based on the usability principle and the gesture database we built in this study, a usability test for in-vehicle gesture control was carried out in a simulated driving cockpit with an Eye-Tracker involved. 14 kinds...
Dedicated Short Range Communications (DSRC) is a wireless communication standard intended for high speed secure communication between vehicles and the infrastructure. In order to overcome the limitations that vehicular environment imposes such as high mobility, IEEE published the 802.11p amendment widely known as Wireless Access in Vehicular Environment (WAVE). To the best of our knowledge, most of...
This paper describes the design of two variants of SENT driver structures, which offer a high degree of immunity against conducted electromagnetic interference (EMI) applied to their output pins: these circuits withstand 20 dBm and 30 dBm of “direct power injection” respectively without any on board capacitive and or resistive loading at the output, while keeping the electromagnetic emission (EME)...
This work presents initial findings of a research project aimed at designing an assistance system able to improve driver ability and reduce accident risk. The proposed system is an innovative Advanced Driver Assistance System based on the integration of two main components: a training procedure based on precision teaching, and a control equipment monitoring driver behavior and providing feedbacks...
DATEX II has been developed to provide a standardized way of communication and exchange of traffic information and it plays an important role for implementing integrated Intelligent Transportation Systems (ITS) in Europe. This standard is suggested for providing information services for safe and secure truck parking places which is considered one of the priority in the ITS Action Plan. The novelty...
Vehicular Ad hoc Networks (VANETs) are an important component of the advanced information networking for inter-operable communications with a wide range of networks. In our previous work, we proposed a method of Enhanced Message Suppression Controller (EMSC) considering delayed ack for vehicular Delay/Disruption Tolerant Networking (DTN). In this paper, we evaluate the performance of our proposed...
There is a high risk of lower limb injury in the rear-end truck accidents. This study aims to explore the biomechanical mechanism of lower limb injuries by establishing finite element (FE) simulation model of different collisions, and the installation height of the rear anti-collision barrier is analyzed. Using the minibus FE model and the total human model for safety (THUMS4.0) to construct the collisions...
The detailed analysis of the standards of roof crush resistance was presented in this paper. Based on the comparison of GB 26134-2010, FMVSS 216 and FMVSS 216a, come to the conclusion about the trend of roof crush resistance standard-stronger crush resistance and less injury potential in rollover accidents. In this paper the test machine, test process and requirements were described in detail. It's...
We propose a hybrid centralized/distributed architecture to coordinate autonomous vehicles at intersections. The centralized job scheduler assigns and updates a service time for every vehicle - the time at which the vehicle should go through the intersection at maximum speed. Then, a distributed controller ensures service time is achieved while avoiding collisions. Efficiency bounds for the coordination...
In this paper we present a novel strategy to compute minimum-time trajectories for quadrotors. In particular, we consider the motion in constrained environments, taking into account the physical limitations of the vehicle. Instead of approaching the optimization problem in its standard time-parameterized formulation, the proposed strategy is based on an appealing re-formulation. Transverse coordinates,...
It is widely known that many traffic accidents occur every year not only in Japan but also throughout the world. Sleepiness or drowsiness, which is the cause of dozing at the wheel, happens regardless of the physical condition of the driver at the time such as after having had meals or at midnight. This indicates that it is too difficult to expect the driver to avoid sleepiness or drowsiness by themselves...
Designing a vehicle sharing system means locating stations which allow users to pick up and give back vehicles. One takes this strategic level decision while anticipating related rebalancing costs. We study here a strategic related bi-level Vehicle Sharing Station Location (VSSL) model, which involves as slave problem a static Vehicle Sharing Rebalancing (VSR) model.
In this paper, we develop a centralized and automated conflict resolution methodology for vehicles that guarantees collision-free motion by coordinating the vehicles' speeds on predetermined paths. A new computationally efficient formulation for collision-free motion constraints of vehicles is proposed. We develop a methodology to maximize the speed and safety distance of vehicles subjected to the...
This paper concerns optimally controlling an autonomous vehicle to perform safe and comfortable overtaking of a slower moving leading vehicle using model predictive control. The contribution of this paper is to further analyze the convex relaxation that was introduced in [1] in order to see how it compares with the standard formulation. The main difference between the formulations is that the sampling...
The assessment of travel time reliability for segments and routes is a rapidly advancing frontier. The increasing availability of probe data is making it possible to monitor reliability in real-time based on individual vehicle data as opposed to ex-post-facto based on averages. This paper examines metrics that can be used to monitor reliability based on probe data. The merits of traditional metrics...
Collaborative Intelligent Transportation Systems are almost part of our everyday life. A C-ITS environment can provide numerous services that soon will become essential to roads' users. The latter resides in improvement of road safety, entertainment, and commercial services. However to provide such services, the C-ITS environment needs an advertisement and dissemination service of the latter. Indeed,...
Emission charging is a new phenomenon in transportation research. Whilst fuel taxation and road tolling are common ways of income raising in many countries, these initiatives are primarily aimed at road infrastructure financing. Worldwide, there has been growing interest in pricing structures designed to manage the growing levels of traffic congestion and, in recent times, an increasing focus on generating...
The U.S. Army Communications-Electronics Research, Development and Engineering Center (CERDEC) is developing technology for a Distributed Satellite Communications (SATCOM) On-The-Move (SOTM) Terminal (DST). Army tactical vehicles are increasingly crowded with many combat and communications systems. The concept of distributed terminals has been developed to address vehicle integration problems, with...
