This paper proposes an autonomous self-parking system in specific parking area. In this system, the vehicle can drive itself and find the parking spaces to park automatically using a smartphone. The system consists of parking place searching, steering control, path tracking and wireless communication. According to the type of the parking space which has recognized by ultrasonic scanning, the system will record the suitable parking space, and send the information to the driver's smartphone via wireless network. The developed system sees a limit at vehicular length of +0.8 m and vehicular width of +1m in parallel and perpendicular lot respectively by using Fuzzy-PID steering tracking control and self-positioning via odometry. After the parking is finished, our system will send a success message to inform the driver. The maximum angle between demonstrated vehicle and connecting line of bordering vehicles is smaller than 5°. Our proposed system is carried out with theoretical algorithm, and hardware integration, and furthermore the result shows the ability of vehicle parking. © 2016 IEEE.

Next-generation telematics solutions are being driven by the maturation of recently deployed intelligent transportation systems, assisted by the integration of and rapid collaboration with information communication technology markets and the automotive industry. Examples of this trend can be found in DSRC contexts in which Wi-Fi and WiMAX have become very relevant in vehicular environments. Comprehensive field trials were conducted and relevant measurements were collected in physical environments to investigate the possible environmental factors that occur in roadside-unit-to-vehicle communication scenarios. In these carefully controlled automobile experiments, the most representative parameters are measured and analyzed for DSRC in dynamic environments (e.g., packet loss, latency, and delay spread). Using a systematic testing procedure and through measurement analysis, the communication performance and the operating reliability of wireless communications can be effectively verified; insightful improvements and helpful suggestions and contributions may thus be achieved for telematics system designs. Furthermore, a practical, reasonable, and standardized testing procedure is proposed, and it can be utilized in equipment verification and product certification. © 1979-2012 IEEE.

This paper discusses the performance of vehicle-to-vehicle (V2V) dedicated short range communications (DSRC). Based on the IEEE 802.11p standard, packets collides at receivers due to hidden note problem. For some applications, it is beneficial to concentrate the radiation energy in certain directions, rather than emitting signal at all directions. Therefore, this paper analyzes the reception performance of V2V communication with different transmit antenna patterns under hidden nodes scenario and explores the employment of reconfigurable antenna technologies to IEEE 802.16p-based DSRC safety applications. Simulation results show that the packet latency can be reduced by up to 66.67% and the unsuccessful packet reception can be decreased by up to 37.6%.

This paper applies exclusive-OR coding to wireless broadcasting systems to increase spectrum efficiency. Due to the inexistence of feedback channel, the transmitter (e.g. DSRC rode side unit) proactively encodes multiple packets into one and the receivers correspondingly recover the faulty packets. Implementing the exclusive-OR coding at physical layer, the proposed scheme is capable of recovering multiple packets. Numerical simulations show that the proposed scheme outperforms the conventional one about 5 dB in signal-to-noise ratio at a target bit error rate of 10-3 for orthogonal frequency division multiplexing systems. © 2012 IEEE.

In order to effectively resolve the environmental issues of energy consumption and the emission of exhaust, electric vehicle with green, clean and energy-saving characteristics has been developed and will become more and more popular on the road. Electric vehicle is powered by its traction battery and needs to be continually charged by coupling to the public power mains, which may result in some interference along the charging cables. To sufficiently prevent the mutual interference between electric vehicle and the power mains, the international vehicle regulation ECE R10 (rev4 & rev5) had put forth the measurement method of current harmonics on electric vehicle's charging system. Therefore, this paper refers to vehicle EMC compliant test procedures to study if the measurement result of current harmonics will be influenced by different measuring method or test duration when the electric vehicle is in REESS (Rechargeable Energy Storage System) charging mode. © 2015 IEEE.

Electric Vehicle has been an international trend so various industries try to evaluate EV cost and commercial viability to get into this market. This study lists each cost parameter that may affect companies' acceptability of market transference from traditional fuel vehicle to Electric Vehicle (EV). Three types of cost parameters are included and they transferable costs, fixed cost, and variable cost. Those cost parameters are environment construction, battery residual value, vehicle maintenance cost, vehicle price without battery, battery price, credit interest, oil market price, electricity market price, battery technology and so on. Here cabin cruiser of official rental type from Taiwan EV pilot projects is an example to compare with the same vehicle type of the fuel vehicle. This study attempts to construct a cost analysis model of the commercial viability. This model will identify the possible break-even point to be the reference for business preliminary measurement based on the pilot projects in Taiwan and provide the suggestion how to shorter the investment time from the analysis result. © 2013 IEEE.

A wireless charging system with magnetic field shaping is proposed. The magnetic field of wireless power transmission is shaped by an innovated structure of resonator, which is named as Shaped Magnetic Field Resonator (SMFR). The magnetic field is shaped within the zone of active transmission and the magnetic flux density is greatly reduced outside the zone of active transmission. Therefore, the Electromagnetic Interference (EMI) to adjacent electric devices is drastically diminished. The high temperature effect of shielding material induced by eddy current on the shielding material is also improved. Besides, the transfer efficiency can be improved. The numerical analysis (Finite Element Analysis) of the proposed resonators by electromagnetic simulation software is carried out for analyzing the shaped magnetic field. Finally, the proposed system is implemented to validate the feasibility. © 2013 IEEE.
