Micro-controlled based Vehicle Safety System Using Dedicated Short Range Communications (DSRC)

摘要

Many accidents occur today when distant objects or roadway impediments are not quickly detected. To avoid these accidents, longer-range safety systems are needed with real time detection capability. To avoid road traffic collisions, vehicles required to be broadcast their position and speed to nearby vehicles periodically. In the above said method, to implement vehicle safety systems with one or two channels and using a single transceiver, micro-controller 89C51 is used as main driver. Emerging systems for active vehicle safety use short range sensors with LOS links, usually to detect vehicles or lane boundaries immediately adjacent to the host vehicle. Typical applications include forward collision warning, adaptive cruise control, and lane keeping.
