Design of controller area network based automated safety system for vehicle

The Controller Area Network (CAN) is a serial bus communication protocol. It defines a standard for efficient and reliable communication between sensor, actuator, controller and other nodes in real-time applications. Generally most of the time people don't know the environmental conditions or Engine unit parameters which may cause problems or sometimes accident. Therefore in this paper we give the detail systematic architecture to provide safety and avoid accident to the vehicles. The goal of the paper is to implement safer, efficient and reliable ARM processor powered automated system for vehicles with decrease in complexity and reduce in wiring compared to the traditional system. We have created a system to connect a group of sensors to a pair of microcontrollers acting as slaves which in turn send the collected data to a master microcontroller through CAN bus technology. The implemented system is using many sensors for data acquisition and CAN bus is the communication medium for data transmission. In addition to this, the data acquired is transmitted to server PC through GSM Module. The current location of system is recorded by GPS Module and can be sent to remote PC on request. Our system is designed to be implemented in vehicles where sensors are used to acquire different parameters of vehicles and send it to owner of vehicle at remote position.
