Study on CAN-Based Lighting and Identifying System for Automobiles


Article Preview

Head lamps, tail lamps, side lamps, roof lamps, alarm signal lamps and other lamps of an automobile constitute a whole lighting system, and identifying devices constitute a guarding system against theft and alarm. In traditional designs, each lamp is independent and controlled artificially by persons, and the automobile cannot show maintenance men which lamp is broken-down and needs mending or replacing. The lamp is either ON or OFF, and its luminance can be adjusted neither automatically nor artificially so that much energy goes to waste. Moreover, lighting system is isolated from identifying system so that they are difficult to manage by a uniform system. Currently, identifying systems of many automobiles key system, door-controlling system, UHF sending/receiving system, alarm system and so on. Once the key is lost or stolen, those persons that have not the ownership can also open the door of the car with it. In this paper, an ISO Standard (ISO 11898) for serial communication- CAN is introduced. Through CAN micro-controller provided by ATMEL, each lamp of lighting system is a component and can be interconnected. Identifying system, in which fingerprint encryption technique is utilized, can also be interconnected with lighting system. This system can be controlled completely, and has some advantages such as smartness, security, low power, low cost, etc.
