This paper presents a low-cost and simple distributed force sensor that is particularly suitable for measuring grip force and hand position on a steering wheel. The sensor can be used in automotive active safety systems that aim at detecting driver’s fatigue, which is a major issue to prevent road accidents. The key point of our approach is to design a prototype of sensor units, so that it can serve as platform for integrating different kinds of sensors into the steering wheel. The CAN controller is used to communicate the values to the main master controller in order to monitor the levels.
In this system the driver’s fatigue is going to detect with the help of touch sensors. The sensors are placed in the steering wheel. The steering wheel is connected with the master controller. The master controller is going to give the intimation with the help of the buzzer. The Master controller here we used to design the system is 8051. The 8051 based microcontroller is interfaced with the LCD for user interface.
