ARM7 Processor based Event Data Recorder using CAN for Vehicular Systems
Publication Date : 28/02/2016
In the recent decades the vehicular systems i.e. various automobiles became the constitutive part of our daily life. As the number of vehicles has grown tremendously, the world has completely reliant on the vehicles for the transportation purpose. But this rise in the number of the vehicles also results in the some serious issues like heavy traffic, improper driving habits, vehicle condition instability etc. Sometimes this leads to the fatal crashes and accidents causing the large amount casualties. This may not only include loss of life but also the major financial losses. These mishaps can’t be eradicated but can be reduced to a greater extent using the Event Data Recorder (EDR) technology. The EDR technology for the ground vehicles is adopted from concept of “Black-Box” in the aviation field where the complete plane data like flight attendant voice, engine conditions, positions etc. are stored in the black-box non volatile memory storage system. The EDR not only records the data comprehensively and accurately in real time but can efficiently reconstruct it, if necessary. Thus, there is the necessity of the controller based high performance EDR. The need of safety demands the smart systems which are able to sense the various data related to the vehicular systems. These data can be vehicular health parameters, driver health parameters or the vehicular environmental parameters. These parameters can’t be stable and uniform throughout the travel. So to keep a track on these parameters certain electronic components i.e. sensors are used. In this paper we are describing the EDR with the Controller Area Technology (CAN) using the ARM7 processor for performance enhancement with the availability of the required data in the memory storage system.
