Xc60 Unit 8 Project
The XC60 SUV will not work in heavy rainfall and snowfall. It is not much capable in unfavourable atmospheric conditions. By using the ultrasonic sensor thought the precaution is given to the driver in advance there is a distance limit. Ultrasonic sensor can only sense the obstacles only up to certain limit. The frequency above 20,000 hertz can be detected by the ultrasonic sensors. There is another limitation also that is, the sensor will detect any abject above its frequency range weather it is danger to the vehicle or not. In our project we are using brainwave sensor to detect the mental condition of the driver based on different frequencies of the sensor. The speed of the vehicle is reduced or stopped automatically considering the emotions of the driver.
III. DESCRIPTION OF PROJECT
A) PROPOSED MODEL
The behaviour of the vehicle and its operation can be executed by maintaining the vehicle speed, brainwave signal generation and by varying the PWM signals.

In the PC the math lab code is written to get the frequency of different voltages that are produced by brainwave sensor. This is given to the ARM processor by the protocol which is responsible by the UART. The ARM will process the signal and the corresponding emotion is displayed on the LCD display and the speed of the DC motor is reduced or increased based on the voltage and by changing the duty cycle of the PWM signal which is derived by the relay driver and the below diagram represents the serial data transmission to the arm through UART and driving the output to different devices which is responsible by the GPIO. The speed of the wheel is reduced based on the generated frequencies and there cross- ponding emotions by differing the PWM signal which is done by writing the embedded C programme in keil software and it is processed by using the ARM
