Automated Vehicle safety system to avoid accidents
[attachment=22677]
The project aims at designing a completely automated vehicle safety system. The system helps in avoiding accidents which usually occur due to over speed and lack of visibility. The project automatically detects the turnings by the steering action and reduces the speed of the vehicle, detects obstacles in the path and reduces the speed if the distance between is less than predefined distance. Also, the system automatically switches the lam according to the light present.
Improving vehicle safety is a key strategy used in addressing international and national road casualty reduction targets and in achieving a safer road traffic system. Vehicle safety addresses the safety of all road users and currently comprises measures to help avoid a crash (crash avoidance). Vehicle design is fundamental to a safe traffic system which requires safe interaction between users, vehicles and the road environment. Vehicle design, which takes account of the behavioral and physical limitations of road users, can address a range of risk factors and help to reduce exposure to risk, crash involvement. This made us to make this project possible.
The controlling device of the whole system is a Microcontroller. MEMS accelerometer, LDR (Light Dependent Resistor), head lamp, dc motors and ultrasonic sensor are interfaced to Microcontroller. The Microcontroller is programmed in such a way that it continuously monitors different parameters and takes actions accordingly. To perform this intelligent task, Microcontroller is loaded with an intelligent program written using embedded ‘C’ language.
The main objectives of the project are:
1. Reduction of over speed at turnings.
2. Reduction of over speed during obstacle presence.
3. Automated light switching.
This project provides us with the learning’s on the following aspects:
1. MEMS accelerometer.
2. Interfacing Motors with Microcontroller.
3. Interfacing MEMS with Microcontroller.
4. Embedded C programming.
The major building blocks of this project are:
1. Regulated Power Supply.
2. Microcontroller.
3. MEMS Accelerometer sensor.
4. LDR (Light Dependent Resistor).
5. Ultrasonic sensor.
6. Head lamp with driver
7. Reset.
8. Crystal oscillator.
9. DC motors with drivers.
10. LED indicators
Software’s used:
1. PIC-C compiler for Embedded C programming.
2. PIC kit 2 programmer for dumping code into Micro controller.
3. Express SCH for Circuit design.
4. Proteus for hardware simulation.
