Vehicle safety distance alarming system

In this paper, a vehicle safety distance alarming system is proposed especially for disabled drivers who need a clear visually and/or audibly alarm. The proposed system is continuously monitoring the actual speed of host vehicle and the actual distance between host vehicle and front vehicle. The system methodology works on adapting the two parameters values, displaying the adapted values digitally, and comparing and manipulating the actual values with the reference values to produce the necessary alarms in order to avoid or reduce the chance of vehicle accidents. Many engineering solutions are proposed in literature review based on microcontrollers, DSP units, or FPGAs. To avoid complexity, special ICs dependence, and to have quick response, the proposed system design is done based on discrete components, and the design is promising an effective and heavy duty system.
