Abstract

Nowadays, road accidents accounts for a large number of deaths and injuries. Sudden braking and driving too closely are one of the reasons causing accidents. Human error is the main factor that causing road accident. Many cases of road accident occur because of human’s unawareness. Therefore, this study was going to design an algorithm that able to alert driver by detecting the range from the detector to the vehicle or object ahead to reduce the occurrence of road accident. This project was focused only on the algorithm implementation and tested by using ultrasonic sensor. This algorithm contained 2 modes. In driving mode, it would detect the rate of change of range between the detector and the vehicle ahead and also detect the safe distance between two vehicles. In parking mode, the detector would detect the safe distance between the detector and the preceding vehicle as well. This helped the vehicle to prevent or to take reduced damage from collisions. The hardware components that have been used in this project were FPGA, a buzzer and a led. An ultrasonic sensor was used for distance detection. The language that has been used to configure FPGA was Verilog and the software that has been used for the configuration of FPGA was Altera Quartus II. It has been proved that the project could be successfully implemented and the objective of this project has been achieved. The comparison between FPGA based collision avoidance alert system and Arduino based collision avoidance alert system has shown that FPGA based collision avoidance alert system has better performance and it was more reliable to be used compared to Arduino based collision avoidance alert system.
