2 Potential Market 6 million car accidents each year in the United States A person dies in a car accident every 12 minutes Car crashes cost each American more than $1,000 a year. NYIT

4 Control System For we do not have a real car for our testing, we have to use a model to demonstrate our idea. Here we choose a toy car as our model. The toy car will stimulate some basic functions of our collision avoidance system. NYIT

5 Main functions Initially the toy car just keeps going forward until it reaches the barrier. NYIT

6 When the toy car comes near the barrier, the sensor will come up with an alarm signal which is regard as an interrupt for our microprocessor. After the interrupt the microprocessor will change its output. When the cars remove controller received the new command, the car can change its path automatically. NYIT

7 Whole system NYIT

8 remote controller Most toy cars remote controller have 4 buttons to control the toy car for 4 directions, but our system is an automatic system we can use these buttons. So we have to build the circuit of the remote controller NYIT

9 remote controller NYIT

10 Video of testing NYIT

11 4 command for 4 directions We use 4 different commands to control the 4 directions of the toy car, here is the main truth table NYIT

12 Microprocessor Design We write program to generate changing outputs of P1.0 & P1.4. The values can be used for the command for controlling the toy car. NYIT

13 Video of microprocessors design

14 Sensor When the toy car comes near the barrier, the sensor will come up with an alarm signal which is regard as an interrupt for our microprocessor. After the interrupt the microprocessor will change its output. When the cars remote controller received the new command, the car can change its path automatically. NYIT

15 The video of the sensors testing NYIT

16 Video of the testing of our whole system.

17 result NYIT

18 Mathematical model We have come up with some mathematic model to stimulate the real situation for cars. The following part will be our theory research on the collision avoidance system. NYIT

19 Doppler effect NYIT

20 The equation is V1=V-F/f*V T=S/V1 NYIT
