1 EENG-491-M03 Watchmen Final Report of Auto-Parking System Members: DaHe Wen, Adam YiRan Huang, Crissh QiuLu Shen, Logan

2 Introduction Auto-parking system is a system that can help people to park their cars by remote control. As we all known,with the development of science and technology, cars are becoming more and more common in our daily life. It becomes more and more difficult to park cars, so it is necessary to work out a system that can help people to park cars.

3 Here are some terrible parking jobs:

6 THIS SYSTEM CAN BE USED IN MANY SITUATIONS WHEN YOU WANT TO PARK. BECAUSE IT HAS NOT BEEN SPREAD OUT, SO IT HAS A LOT OF PROFITS IN THE FUTURE Potential Market

7 That is why we want to design an auto-parking system to solve this problem! If we have this auto- parking system, we can get rid of these awful situation above!

8 1. HANDLE THE SIGNAL OF PARKING SENSOR 2. SIMULATE NORMAL IN COMPUTER 3. CONNECT THE CIRCUIT SUCCESSFUL 4. CONTROL THE MODEL WELL Expectation

9 THEN WE WILL SHOW YOU A IDEAL DEMO

10 THE FIRST IS ABOUT THE HARDWARE, WE CAN USE MODEL TO SIMULATE. THE MOST IMPORTANT PART IS THE SELECTION OF SENSOR CHIP AND MODEL. Process

11 The standard of parking sensor: 1.Should have the reversing radar display, audible alarm, regional alerts and location instructions 2.The detection range should between 0.3m to 1.5m 3. The cost should not be too expensive

12 FINALLY WE CHOOSE PYLES PRODUCT-----WATCHDOG

13 THEN WE WENT TO THE LAB TO TEST THE CHIP:

14 the instruction of the parking sensor:

15 WE HAVE TO DO THREE TESTS: 1.The warning distance test 2.The obstacle location display test 3.The detection dead angle test

16 AFTER THAT THREE TESTS, WE FIND THE SENSOR IS GOOD

17 THEN WE WILL SELECT MODELS AT FIRST WE WANT TO GET TOY CARS

18

19 THEN WE FIND TWO PROBLEMS 1.There is no place to set up sensors 2.Can not change the direction obviously

20 THUS WE CHANGE TO USE ROBOT

21 AFTER THE TRANSFORMATION:

22 THE SECOND IS SIMULATING THE PROCESS OF THE AUTO-PARKING SYSTEM. THIS IS ALSO QUITE AN IMPORTANT PART OF THIS PROJECT!

23 The first condition: the perpendicular parking

24 WE SHOULD USE APPLET TO DO THE SIMULATION The formula is

25

26 The second condition: the parallel parking

27

28

29 THE THIRD IS DESIGNING THE CONTROL SYSTEM OF THE AUTO- PARKING SYSTEM. THIS IS THE CORE PART OF THIS PROJECT!

30 WHAT WE WANT TO REALIZE IS 1.Get the signal of parking sensor 2. Understand how the computer get the feedback 3. When should the robot rotate

31 WE HAVE MEASURED THAT The signals of parking sensor are divided into two situations

32 WHEN THE DISTANCE IS BIGGER THAN 0.3M

33 WHEN THE DISTANCE IS SMALLER THAN 0.3M

34 SO WE NEED AMPLIFIER TO MAGNIFY THE CURRENT

35 BECAUSE WE NEED TO SWITCH THE CIRCUIT, SO THE ELECTROMAGNET RELAY IS ALSO NEEDED.

36 THEN WE CAN GRAPH THE CIRCUIT

37 WE PUT IT INTO REALITY

38 then the system will get the feedback and calculation

39 NEXT THE SYSTEM WILL GIVE THE COMMAND TO CIRCUIT AND LET IT ROTATE

40 HERE IS OUR EXPERIMENT DEMO

41 REALISTIC CONSTRAINTS Because the response time from the sensor is so long, so we have failed many times, the sensor is not in good use as we thought. But our budget is limited, so we can not get a more sensitive sensor.

42 BECAUSE IT IS JUST A TEST EXPERIMENT, SO THERE ARE LOTS OF PROBLEMS EXISTING: THE VOLTAGE IS UNSTABLE, THE WIRE CONNECTION IS BROKEN, THE SIGNAL OF REMOTE CONTROL IS BLOCKED, ETC. WE HAVE FAILED MANY TIMES, BUT SOMETIMES WE STILL FIND THAT THE ROBOT CAN DO THE ROTATION WHEN IT GETS CLOSE TO OBSTACLES. THAT PROVED WE CAN USE THE SENSORS SIGNALS AND GIVE COMMANDS TO THE ROBOT. Conclusion

43 IF YOU WANT TO KNOW MORE, PLEASE TAKE A FOCUS ON OUR WEBSITE:

44 THANK FOR YOUR PATIENT!

45 Appendix : Integral steering linkage formula

46 Disconnect style steering linkage symmetrical formula

47 Disconnect style steering linkage of non-symmetric formula
