1. Introduction
Since the market demands varied over the last 30 years, automotive manufacturers have been focusing on improving users’ driving experience for a long period while developing advanced electronic-based technologies, with respect to requirements such as convenience, safety, fuel efficiency and etc. However, with more functions achieved, a large quantity of wires individually connected to different electronical control units(ECUs) needs to be involved in order to transfer signals from sensors to ECUs, thus making the entire vehicle system significantly complex, heavy, costly and less reliable. This issue was foreseen by engineers and could not be solved properly until the introduction of vehicle communication network in which ECUs interchanges information alone the bus with much less wirings required. Within the following sections, in order to ensure accuracy for final investigation result, a Toyota Prius 2012 model is chosen for researching on how information required is processed by each control unit after being detected by those related sensors. Based upon investigation mentioned, discussion on benefits of using in-vehicle network will be further taken with respect to weight and cost savings.

2. Control units, sensors and information
This section identifies a number of sensors used by different types of ECU and briefly discusses information each ECU requires for different uses.
2.1 Engine Control Unit (ECU)
The Actron CP9680 AutoScanner is one of the most well-known OBD2 scanners on the market. A big reason for this scanner’s popularity, is the scanner’s reputation for trustworthiness and reliability. It not only accurately reads check engine lights codes, it also providing vehicle owners with the best possible solutions for fixing and clearing CEL codes. The technology that powers this impressive database of information is called CodeConnect technology and is exclusive to the Actron line of OBD2 scanners.
Self driving vehicles is a huge change in our society. We are taking the next step into the future and creating something bigger than ever. Driverless cars can be a good thing and a bad thing in todays society. We depend on so many things now, the older we get and the more time goes on, the lazier we get. Being Americans, we are putting our thoughts and ideas to the ultimate test to create something so dangerous but so efficient. We have thought of ideas that would make our lives "easier" and less stressful. In this paper I will describe how driverless cars work, the current problems and setbacks that we are having, and how this new technology is being put to use today.
Now here is a simple to control robotic car using Bluetooth module and 89C51 microcontroller with android Smartphone device. The controlling devices of the whole system are a microcontroller. Bluetooth module, DC motors are interfaced to the microcontroller. The data receive by the Bluetooth module from android smart phone is fed as input to the controller. The controller acts accordingly on the DC motor of the robot. The robot in the project can be made to move in all the four directions using the android phone. The direction of the robot is indicators using LED indicators of the Robot system. In achieving the task the controller is loaded with program written using Embedded ‘C’ Languages using KEIL and Proteus software for simulation of
CE 1.3.3 I studied plant system architecture and the interfaces with the distributed control system (DCS) and emergency control system (ESD) of Honeywell,as this was key aspect for interface. Since the data like signal values, alarms, trips etc. from MCMS was serially interfaced by either Modbus or OPC(OLE for Process Control) to DCS .The trip signals from MCMS system was hardwired signals to ESD, since these are very critical signals for machine shut down.
Cars are something that almost every person has or will use in their everyday life or need to use their car to get to and from work or school everyday. Well in this paper you will learn about what technology has done to change the Automotive Industry as well as your everyday life. This paper will be focusing on the Technologies inside of the car, along with the Technologies that keep you safe and also a little bit about Self-Driving Cars. So fasten your seatbelts while you are reading this paper.
The use of IoT in the development of autonomous vehicles has led to the general reduction of fatalities (Sheng et.al, 2013). The reduction of fatalities is from the following aspects of driverless cars which are improved on by the use of IoT in the vehicle technology.
TM4, the industrial partner, is a leading manufacturer and supplier of traction motors and drives for electric vehicle industry in Canada. As a drive manufacturer, they always aim to provide solution which is energy efficient with small footprint. In order to achieve this, they always look for alternative software and hardware solutions. Software modifications, which may improve the system performance in comparison to their existing drive control strategy without increasing the size of the system, are always sought after for continuous improvement of their system. In this regards, the internship is relevant to them for exploring alternative control strategies.
All electronics malfunction, it there were to be any kind of malfunction, the car could crash and cause very serious injury. Millions of people die in car accidents everyday. This could be another way a life could be taken away. There is an easy way to prevent the car from malfunctioning. All you have to do is buy a car that lets you in full control of the car. That way, you don’t have to worry about any kind of malfunction.
Huffman Trucking has offices paired with plants in four states: California, Missouri, New Jersey, and Ohio. Huffman has grown both organically and through acquisition. The tremendous growth experienced by the company has also shined the light on some growing pains. Each of the four locations have independently managed networks including telephony which has resulted in disconnected systems that require independent investment for upgrades, support, and maintenance and lacks the ability to leverage investments across the organization. The end result includes multiple proprietary telephony platforms and gateways that leave the organization unable to reduce overhead cost in this area. There is some good
The deceleration of vehicle speed is demonstrated successfully with the embedded system. Along with this, android based notification system consisting of image and voice output worked efficiently during the testing of embedded system. This work in progress opens opportunities for additional analysis and implementations. The measuring characteristics of sensors are for low speed conditions. When applied in higher speed situations, high-end and enhanced senors with higher range can be implemented. The notification app developed is only for android platform, in future the application can be ported to other
The article describes three formats of in-vehicle feedback; visual, haptic, and audio. Each of the three formats to be broke down into various systems and functions. Very similar to a database containing tables, rows, and attributes. In the visual table, there are four rows one of which is the dashboard. The dashboard contains several aids including gauges, on-board diagnostics, GPS, and lamps. The haptic table contains the break/ throttle row, were pedal pulsation will notify the operator of activated antilock-brakes or traction control. Jensen
Note: All the readings and calculations are performed at “outside station”. It uses the control Logix platform utilizing a GuardLogix safety PLC.
The concept of internet of vehicle is shown in Fig.10. The converging technologies of IoV are related to electric vehicle, autonomous vehicle etc. The IoV can also deals with the vehicle to vehicle (V2V), vehicle to device (V2D), vehicle to infrastructure (V2I) and vehicle to grid (V2G) communication.
The BMW Group is conducting research into systems that optimize the interaction between driver, car and environment in
Automobile industry is expand and improved time to time start from 1769 until now. We are now got a comfortable and convenient car. Different with last few centuries that the only can run 10 mph and only can last for 10 to 15 minutes. Before go furthers, lets understand the meaning of automobile. According to the Merriam-Webster automobile is four-wheeled automotive vehicle that been designed for people transportation and commonly used an internal-combustion engine that used volatile fuel. Nowadays, we can see a lot of change when the modern automobile consists of about 14,000 parts and complex systems. These include the body of the car, the internal-combustion engine, which powers the car by means of a transmission and the electrical system, which includes a battery, brake system, distributor, alternator, and other devices.
