Modelling and Simulation of Vibration Sensor for Vehicle Accident

Many sensors have been applied as accident detectors. This paper proposes the application of the vibration sensor, model SPM8667VC for accident detecting in accident reporting systems. The sensor parameters were put into consideration alongside with its operational voltage of 500mV. Various mathematical models were developed to cater for the mechanical and electrical properties of the sensor. This led to the development of a Simulink which was simulated on MATLAB 2014a environment for the various states of accident. The simulation result led to the formulation of a mathematical model that caters for the various levels of accident based on threshold voltages. These levels are categorized as mild accident with a voltage of 150mV, medium accident with a voltage of 280mV and severe accident with a voltage of 580mV. The various levels determine accident severity and when apply in accident reporting system, guide rescuers decision to embark on rescue mission or not.
