HAPTIC SEAT ALERT SYSTEM IN MOTORCYCLE TO REDUCE ACCIDENTS

Abstract eng:
We live in a world, where speed plays a more vital role. Though speed is more important safety is considered essential. India has recorded most number of road accident per Annam about 1,35,000 annually. The country has over taken China and now has the worst road traffic accident rate worldwide. It is found that 25 percent of the total death in the road accidents are two-wheelers. The statistics shows that, one serious road accident in the country occurs every minute and 16 die on Indian roads every hour.1214 road crashes occur every day in India. Thus an alerting system is necessary to alert the motorist, in any conditions such as over speed and rash driving also to indicate the approaching of the closer rear vehicles. The Haptic seat alert system in motorcycle is a combination of both Mechanical and Electronics operation. This system alerts the driver by producing vibration in the seat, with the help of dc vibrating motor. The system consist of Ultrasonic sensors, Electronic controlling unit and the dc vibrating motor. The Ultrasonic sensor helps in transmitting and receiving signals. The change in the signal is noted with the help of peripheral integrated circuit (PIC) this send signals to the H-Bridge motor driver. The H-Bridge motor driver controls the dc vibrating motor by using Pulse Width Modulator (PWM). The major feature in this setup is that, the right portion of the seat vibrates, only if the vehicle approach in the rear right side and the left portion of the seat vibrates only if the vehicle approach in the rear left side. This setup proves efficient and help in saving life.
