Push button car starter RFID
Rutcgr18
Posts: 47
Ok guys and girls.· This is my first real project with the stamp.· Its a bit over my head but what the heck.
So what i want to do is all the new cars these days use RFID and push button start for there cars.· No keys needed.· So i was plaining on coverting my 05 nissan patherfinder to this.· This is my thought so far. Also for the test on the bench i will be using leds instead of the acutal car.
Inputs
Pin1= the input check if the rfid is in the car.· Basicly the rfid moduale would just swith 12 hi to that pin.
PIN2= Brake.· This pin will check ot see if the brake pedal is pused.· 12v Hi
Pin3= The button to start the car. would apply 12v HI once pushed
Outputs
Pin4= Acceries Example to turn on radio LED YELLOW
Pin5= Igniton LED Green
Pin6= Starter.· This pin would stay on for a set amount of time. LED RED
So IF PIN1,PIN2 are high and i hit the button (pin3)·i would then turn all three outpins on(pin4-6)
If PIN1 is high and i hit the button it should turn on only PIN4.
If PIN1 is high and PIN4 is on and i hit the button again PIN5 should turn on and PIN4 Should stay on.
If i hit it a third time and PIN1 is high and PIN4-5 are on it should then turn PIN(4-6) off.· Example of shutting the car off.
I know kinda complicated i think.· Please let me kknow if you need clairfaction.
Thanks
MIKE

you may find you need to somehow disable your key colum lock so you can change gears and turn your wheel, i sugest using some type of mechanical interlock with a solenoid so if you kept this in your car and agian your bs2 were to fail, you wouldnt loose power and steering driving 55 down the road.
