3-level automotive safety warning and alert system using FPGA

This paper presents a safety warning system on automotive with 3 warning level according to conditions. The system is designed based on the Lane Departure Warning (LDW) system. This system is expected to reduce or minimize the road accident happened due to risky and careless driving. In the system, several sensors are embedded such as sonar wave sensors and camera. The system is designed using FPGA DE1 board as the design currently is in prototype stage. Several interface such as LCD, LED, and seven segment display are used. The maximum response time is about 3ms, and for longer range detection of sonar wave sensor, the longer the time required. Thus, the blind spot detection module and the camera module are independent, to improve the response time of the system, even though the warning alarm gives are dependent on each other.
