Grounding for Hybrid Vehicles
Vehicular communications, among vehicles and between vehicles and infrastructures are based on wireless communication technology known as dedicated short range communications (DSRC), which are in great development with the aim of reduce the traffic problems and improve the road safety. This study is based on the development of a solution to an antenna to be used in the mobile module, usually named On-Board Unit (OBU). The antenna should have characteristics that meet the requirements for new DSRC at 5.9 GHz band in Europe. The proposed antenna is a printed monopole with a reduced size that presents an omnidirectional radiation pattern in the horizontal plane and allows communications independently of the direction of vehicles. The wide bandwidth obtained is to enough to encompass the other band for DSRC communications used in Europe, at 5.8 GHz, and become more tolerant to manufacturing problems.
The existing theory and technology provides new means for on board system of logistics traffic. The use of navigation and communication platform will be an integral part of on board unit (OBU). Applications on OBU have been growing substantially in recent years to reduce the probability of accidents. On navigation and locating part, locating solution innovation is now driven by requirements of location based services on logistics. The fact is mass users distributing in urban canyons, indoors or in shaded areas where Global Navigation Satellite Systems (GNSS) signals can be attenuated, so the navigation platform generally need be supported by combining GNSS with wireless network and wireless sensor network. On communication part, it is necessary to establish a vehicle-to-vehicle (V2V) and vehicle-to- infrastructure (V2I) communication unit beyond the consideration of the road safety. In this paper, the architecture of OBU which have an advanced navigation and communication plat are presented first. Then the fundamental location estimation combined with GNSS, 3G wireless networks and WSN is developed. Finally, the OBU semi-physical Simulation platform is developed. Navigation and communication platform in OBU for safety services is demonstrated in this paper with its seamless integration feature.
Direct RF undersampling is an effective technique for miniaturization of HTS on-board unit. It can realize a reception bandwidth up to half of the sampling frequency fs/2 theoretically. However, if it expands reception bandwidth until fs/2, roll-off part of an anti-aliasing filter effects seriously on folding noise. In this paper, we propose a new folding noise model for broadband considering a roll-off part of an anti-aliasing filter. Based on the proposed model, 28 GHz band direct RF undersampling broadband receiver is designed and evaluated. As a result, the reception bandwidth is achieved 94% of fs/2.
This paper proposes and assesses a Big Data Platform for effective storage and analysis of On Board Unit (OBU) data related to the mobility of trucks in Belgium. The large volume and the streaming nature of the OBU data requires the setup of a big data platform for an efficient collection, storage and analysis. The solution relies on (i) the Hadoop Distributed File System (HDFS) to store data, (ii) the Apache Parquet format for data compression and columnar storage, and (iii) Spark for parallel and streaming processing of data. Data replication, compression and columnar storage ensure robustness to node failure, data distribution, and faster access to data.
A specific MCU design of On board Unit (OBU) in Electronic Toll Collection (ETC) system is proposed in this paper. According to the ETC applications,this MCU is designed to have the minimum application system. Results show that this MCU design scheme is feasible and fulfills the requirements of the central control chip used for OBU in ETC system. The MCU has about 113,000 gates, and its area is 642.74 μm × 494.20 μm under SMIC 65nm technology. The average power consumption is 98μW. Compared with the general MCU, the MCU has a larger advantage in ETC application.
As the most main part of constituting Vehicular Ad Hoc Networks (VANETs), On- Board Unit (OBU) which is installed on vehicle is crucial to the development and popularization of such networks. In this paper, we propose a New OBU (NOBU) scheme of combining smart phone with Customized 802.11p Device. Since smart phone is generally equipped with powerful computing and storing device, GPS and electronic map, in our proposed scheme, it is utilized as a platform to run routing strategy and all kinds of applications of VANETs. By USB cable, the smart phone can readily connect with a customized 802.11p device, and thus access VANETs. As smart phones have been becoming so popular that almost every driver own one, the scheme will provide vehicles, especially for low-and middle-price ones, with a chance to access VANETs in a feasible, low-cost and efficient way. Simulation results based on a real map demonstrated the effectiveness of the proposed scheme.
The evaluation data of EV in motion or in charging is a new research to reveal the EV performance and user behaviour. ARTC (Automotive Research & Testing Center) is devoted to the study of EVs for years, and in charge of the data evaluation in Taiwan i-EV pilot project. With the project's purpose, ARTC designs the flow of this task. First of all, the data need to be gathered including status, speed, date/time stamp, battery SOC on the vehicle are automatically transferred to OBU (On-Board Unit) through CAN protocol. The OBU developed by ARTC sends the data via 3G/GPRS to data collection platform. Afterward, the data are processed and analyzed by statistical method to address the results such as the driving distance, the distribution of the battery SOC etc. There are two operational models from the EV pilot projects at megalopolises in Taiwan. One is service car for public affairs and the other is rental car for the public. The data present the differences between various areas and purposes. The outcomes can help the government to make policy, fleet to earn the largest benefits, and car factory to adjust the car design.
Thailand Expressway implements an electronic toll collection system (ETC) that automatically deducts tolls from prepaid account. ETC system uses the dedicated short-range communications (DSRC) technology by semi-passive RFID at frequency of 5.8 GHz in order to communicate between the transceiver called the road side unit (RSU) and the transponder called the on board unit (OBU). The lifetime of OBU depends on a build-in battery and the signal strength of communication. Therefore, the lifetime may be expanded by replacing a build- in battery or increasing the signal strength of OBU. It is not feasible to replace a build-in battery. The best way to expand the lifetime of OBU is to increase the signal strength. This paper presents the study of OBU in order to analyze the relation between the physical components and the necessary design parameters of an antenna. The results illustrate that the parasitic elements of an antenna play an important role in the design parameters. It is shown that the antenna return loss (at operated frequency of 5.8 GHz) is improved from -5.44 dB to -19.90 dB after including the bottom parasitic element with the loop antenna. By adding both bottom and top parasitic element with the loop antenna. The directivity of antenna is increased from 2.52 dB to 8.03 dB. Simulation results show that both top and bottom parasitic element have impact on the design parameter (return loss and directivity of antenna). The performance of OBU can be improved by adding a top and a bottom parasitic element.

The communications interface of this system was implemented by using WebSockets and JSON messages. The prototype was tested and found to be functional, complying the normativity of the Public Transportation of Medellin.
Some of the mobility challenges in the cities can be approached with the Internet of Things, Cloud Computing, and Fog Computing. In this work we consider the city as a system of systems and focus on the interaction of those entities with the mobility systems. A key element that allows this interaction is a vehicle on-board unit. In this work we address the interconnection, enabling technologies, interoperability, scalability, geo-distribution and time constrains aspects in the architectural design of mobility systems. For this we propose the On-Board Unit architecture and cover three different levels of technification in information and communication technologies. Based on this differentiation we are able to include Cloud and Fog Computing into our proposed designs.
