HUMAN SECURITY IN A VEHICLE USING CAN TECHNOLOGY

In last two decades there is drastic change in techonlogy and there are recent changes to the field of mechanical engineering as automobile industry is having a demand on a very techosuportive platform. Mechatronics is emerging and booming now a days and many mechanical systems are replaced by mechatronics systems due to high prisions and accuracy. Even use of mechatronics drastically increased the performance of automobile and other systems in order to get more and more intelligent and power efficient systems. In this project we not only going to enhance the performance of the systems but also add some desirable features to vehicle in order to provide safety measures to the driver. We are also providing a automatic system which

Avoiding Vehicle Theft is making buzz in present automobile industry. Design and development of a theft control system for an automobile, can be achieved by making use of GPS feature of mobile phone. The developed system makes use of an mobile phone that is embedded in the vehicle with an interfacing to Engine Control Module(ECM) through Control Area Network (CAN) Bus, which is in turn, communicated to the ECM. The vehicle being stolen can be stopped by using GPS feature of mobile phone and this information is used by the owner of the vehicle for future processing. The owner sends the message to the mobile which is embedded in the vehicle which has stolen which in turn controls the vehicles engine by locking the working of the engine immediately. The developed system accept the message and broadcasted to the Vehicle Network through CAN Bus. The engine can be unlocked only by the owner of the vehicle by sending the message again. The goal behind the design is to develop security for vehicles and embedded system to communicate with engine of the vehicle.

— Currently almost of the public having an own vehicle, theft is happening on parking and sometimes driving insecurity places. The safe of vehicles is extremely essential for public vehicles. Vehicle tracking and locking system installed in the vehicle, to track the place and locking engine motor. The place of the vehicle identified using Global Positioning system (GPS) and Global system mobile communication (GSM). These systems constantly watch a moving Vehicle and report the status on demand. When the theft identified, the responsible person send SMS to the microcontroller, then microcontroller issue the control signals to stop the engine motor. Authorized person need to send the password to controller to restart the vehicle and open the door. This is more secured, reliable and low cost.

In controlling the vehicle autonomously using various electronic control modules (ECU " s), usually need to make some decisions with integrated actions in real time with only incomplete information. The CAN (Controller Area Network) serial bus system makes a crucial contribution here with to its specific properties. This paper describes about development of CAN based automobile control system which includes Body control and comfort electronics subsystem of automobile to address comfort in drive feature. INTRODUCTION The modern automobile has progressed greatly in the last few years. Just as our everyday consumer life has become sophisticated, our transportation has followed suit. Just how complex the modern automobile has become, though, is most likely not known by the average person. Here is an effort made in design and implementation of CAN protocol based Automobile control system for better understanding the automobile system. Automobile instrument assembly consist of various nodes linked with each other by CAN bus. Nodes are nothing but ECU " s(electronic control unit) that consisting of CAN controller and micro-controller to which various I/O devices as sensors, actuators are attached, identifies and processes the required data. Modern motor vehicles can contains over hundred ECUs which are interconnected by the CAN Bus network. The system could be well illustrated by figure 1 below, showing In-Vehicle CAN Bus Network joining various ECUs.

Due to increasing technology Automotive Electronics sector is now becoming more in demand. Most of luxurious vehicles consist of automatic controls of different parameters present in the car surrounding. As more and more latest applications are available on vehicle information system, the refore connection between the vehicle bus network and information system is now becoming a trend. Basically in automobile industries for communication, the CAN protocol is used . The proposed syst em presents the development and implementation of the digital driving system for a semi - autonomous vehicle for improving the driver vehicle interface and CAN provide technological development for future applications in vehicle’s information system. The pro posed system is use to monitor driver’s behaviour , Drowsiness and Alcohol with the help of sensors. System contains controller b lock designed using A RM Cortex M - 3 , alcohol and sensors, CAN controller, GPS and GSM modules

A vehicle security system combines the installation of an electronic device in a vehicle, or fleet of vehicles, with purposedesigned computer software to enable the owner or a third party to track the vehicle's location, collecting data in the process. Modern vehicle tracking systems commonly use Global Positioning System (GPS) technology for locating the vehicle, but other types of automatic vehicle location technology can also be used. In the proposed system if someone tries to steal the car, the microcontroller MSP430FG4618 gets an interrupt through a switch mechanism connected to the system and commands the GSM modem to send an SMS. The GSM modem SIM900A interfaced to the microcontroller, receives the message, the output of which activates a mechanism that disables the ignition of the vehicle resulting in stopping the vehicle. The proposed system is further enhanced by integrating a GPS system, which will give exact position of the vehicle in terms of its latitude and longitude using NMEA data. GPS and GSM technologies enable the vehicle owners to track and monitor the vehicle at anytime from anywhere.

In today's world almost every common man owns a vehicle. Theft is a common issue which everyone faces in parking and sometimes driving near insecure places. Vehicle security and accident prevention is more challenging. So in order to bring a solution for this problem the proposed system can be implemented. Vehicle security enhancement and accident prevention system can be developed through tracking and locking, fuel theft, accident detection and prevention, driver fatigue, pollution control and speed limiting with efficient vehicle management system. The need for this is to provide security to the vehicles by engine locking system which prevents the vehicle from unauthorized access. It can also prove beneficial to find out the exact location of the accident. This proposed work is an attempt to design such a system using global positioning system (GPS) to determine the precise location of a object, person or other asset to which it is attached and to transmit this information using GSM modem.

The need for this project is to provide security to the vehicles by engine locking system which prevents the vehicle from unauthorised access. This technique helps to find out the exact location of the accident and with the help of server an emergency vehicle can be sent to the exact location to reduce the human life loss. It also detects the behaviour of the driver through sensors whether he/she is drowsy or drunk, so that occurrence of accident can be prevented. The place of the vehicle identified using Global Positioning system (GPS) and Global system mobile communication (GSM). This is more secured, reliable and low cost.
