BAT Appt 6212 Technology Project (Automotive)

week 8
18th April 2014
It was the middle of the semester time,  the break begins from 18th but on the other side was not a rest day for us we have to make sure we have sufficient data and for that we begin our search on some logic gates and circuits so as to try to make it and think which way we can make it. On the other side we loaned the book called "Performance Electronics for Cars" from Simon so as to go through some circuit diagrams and as we were plan to follow the gant chart as the next demonstration was after stage 2 where we planned to talk about the outputs.

week 7
11th March 2014

Was the day of our presentation, we started describing the 3 sensors for the input we are going to use. searching on them made me learn many things like the way they performs there functions and how they work as starting from the very first sensor which is

VSS (Vehicle Speed Sensor): As we know seat belt is one of the most safest part when it comes to be safety in vehicle, and all the vehicles in automotive industry use it.By the safety belt designers in recent years a Reed Switch sensor has been discovered as being the most reliable and best way to detect the engagement of seat belt.
Features/Functions:

•Can activate & control the switching function from the one side of the seat belt buckle.

•Is designed to handle the high shock environments

•Can be operated in dirty environments

•Is hermetically sealed

•Lots of reliable switching operation

•Reliable switching

•Dynamically tested contacts

> Second sensors which i searched n presented was the SOS

SOS(Seat Occupany Sensor): The occupancy sensor consist of the flexible sensor mat, which in inserted or installed into the vehicle seats.The mat consists of two sandwiched carriers sheets held together.

•Increase pressure on the mat will cause the electrical resistance change, which informs the system that the seat is occupied or not.

•The vacant or occupied seat will correspond to an open or short circuit.

•The occupancy on the seat is only detected for higher weight depending on the specs mostly 40 kg.

•The occupant detection technology will not affected by the

• Weight,  seat belt tension, or movement of the passenger.

•Furthermore, the system will not be triggered by inanimate objects placed on the seat.

FEATURES OF SOS:

·Senses immediate presence of pressure applied to pad.

·Bend Sensor / Potentiometer.

·Small size is ideal for embedded applications.

·User defined thresholds for alerts and notifications

>And 3rd sensor was the VSS(vehicle speed sensor which was performed by my group mate)

 week 6, we started more search as for our next demonstration presentation, we consider to present few more data on our inputs for this demonstration, which are 

•Inputs

1.SBS  2.VSS  3.SOS 

1. Seat belt Sensor:

2.Vehicle speed sensor:

3. SOS

              Above all three sensors are the input for are project and mainly are presentation was on how they work and there functions.

week 5
28/03/2014

In today's lesson we had to do a presentation on the topic we choose along with the initial report on it. Me and my group mate Anuj presented the basic information on our project which was named as "No Seat Belt No Drive". so our idea was if the vehicle is driving over the 20km/hr and the seat belt is not buckled then the driver can’t drive over 20km/hr and it will bring the throttle on the ideal speed. from which it will restrict the driver to drive above the  provided limit and provides more security or safety for the passenger as well as other road users. we will be using logic table and few sensors to do that or programmable chip. We will discuss further with our supervisors and further move on with the project.

week 4
21/03/14
It was the day of presentation for all of them who have selected the idea last week and finalised to work on it,but due to too many ideas we were unable to work on one, but with some more ideas we came back to roman to talk about them and finalise one of them. So now we thought about the safety in todays vehicles, so we selected the seat belt to work on with, so if the driver n passenger is not wearing the seat belt it will not allow to drive it and he said yes for this project. Then we had a talk to Simon about this and took some ideas out like how we gonna restrict the drive.
