Abstract: Wear and corrosion are problems prevalent in the industrialized world. One way to overcome this matter is the process of coating with a thermal spray coating. The coating process is categorized into two processes based on the heat source, i.e., combustion and electric. One example of combustion process is the high-velocity oxygen fuel (HVOF). The HVOF system which is operated manually has been studied in previous works. Computerized HVOF system is developed and manufactured in this study to improve reproducibility of coating and safety of operator. ATMega16 microcontroller was connected with several sensors (oxygen mass flow controller, nitrogen mass flow controller, propane mass flow controller, and pressure sensor), and Visual Studio.Net 2013 was used to create a graphic user interface (GUI). Based on test results obtained, it was found that the GUI successfully communicated using serial communications and could access the input/output (I/O) required by the microcontroller. Combinaton of gas mass flow controller and pressure sensors result in precise control of oxy-fuel combustion process.

Abstract: Drowsy driving is deemed to be an important factor in many traffic accidents. Current vigilance detection systems are usually based on the expression of the driver recorded in video. These existing systems can only warning the driver when they are in fatigue and video-based analysis can’t detect the driver’s Pseudo-fatigue. In this paper, we propose a novel vehicle speed control based on driver’s vigilance detection using electroencephalographic (EEG) and Sparse representation. The proposed system consists of the vigilance detection module and the vehicle speed control module. In vigilance detection module, preprocessing and sparse representation classification (SRC), the classification of driver’s vigilance, are implemented in EEG to get the vigilance degree of driver. In vehicle speed control module, the Electronic Control Unit (ECU) control the electronic throttle and Anti-lock Brake System (ABS) so as to make vehicle speed keeping at the original level or down to zero according to the signal of vigilance degree. The last performance evaluation demonstrates the validity of the proposed vehicle speed control based on driver’s vigilance.

Abstract: Based on the issue of the communication between two FlexRay nodes, this paper proposes a new design straight by illustrating the mechanism with respect to the way of performing it by both hardware and software means. The important part of the mechanism is demonstrated in detail. The experiments through two Electronic Control Units (ECUs) show that the design can realize the communication between two FlexRay nodes well.

Abstract: With increasing of road network and vehicle’s specification, most of new vehicles will be driven exceeding the posted speed limit. More than half of the fatalities in motor vehicle accidents have been proved to be due to over speeding. To improve the safety of cars EURO- NCAP (European New Car Assessment Program) has a safety rating category that rewards manufacturers for the fitment of electronic stability control. In this paper, we describe the method of using a Microcontroller to Monitor and Reduce the Speed of Cars with electronic fuel pedals. We propose a continuous monitoring method based on speedometer feedback and then vary the input from the cars fuel pedal input that is going into the Electronic Control Unit (ECU) to reduce the cars’ speed. A conceptual model was built to demonstrate the concept using a PIC18 Microcontroller. The fuel pedal is also known as Electronic Throttle Controller (ETC).

Abstract: In the past decade automotive industries being faced the exponential increase of in-vehicle electronic devices. The hydraulic systems are replaced with sophisticated electronic systems. Market demands for exploiting new in-vehicle technologies such as multimedia systems, internet access, GPS, Mobile communication, internal private network; engine, body and power train intelligent control and monitoring systems are increasing daily. These new needs make the wire-harness as physical pathway for power and data more complex. The amount of different data types transmission in vehicle networking requires higher bandwidth and subsequently applying expensive and advanced equipment. Furthermore functions and facilities lead to raise the number of electronic control units (ECU). The high cost of manufacturing and implementing the previous equipment and systems only can be justified to luxury vehicles high prices. This paper presents a conceptual model of in-vehicle networking which would lead to the appliance of considerable portion of these advanced systems in non-luxury vehicles. In this context, polymer optical fibers (POF) exploited to achieve high speed bandwidth and cost-effective solution to transfer huge amount of data and one ECU to control and manage body/cabin electronic devices. This paper suggests three red, blue and green lights for transferring video/audio, communication data network such as internet/vehicle internal network and body/cabin command lines respectively. Moreover, this concept model claims for reducing wire-harness with integration of command lines into multiplexed POF line.

Abstract: Hardware-in-the-loop simulation (HILS) is a scheme that incorporates some hardware components of primary concern in the numerical simulation environment. This paper discusses the implementation and benefits of using the HIL testing system for electronic control unit of dual-clutch transmission (DCT) vehicle.
