All Encompasing Car Computer Project. HVAC questions.
I am about to start what will no doubt be a long, arduous and expensive journey into the world of Car Computers.
I'm probably taking the 'bite of more than you can chew and then chew like hell approach' as I intend for the touch screen to control the HVAC system and preform all the usual Infotainment duties aswell as digital gauges etc.
Whilst the Infotainment and gauge side of the system can be a work in progress, I really need to get the HVAC system sorted in theory and perhaps see a few examples before taking the plunge as I was intending on using a 12.1 16:9 inch touchscreen in portrait landscape built into the console area which will see the old hvac binned.
The HVAC air distribution in the car is predominately vacuum operated with the exception of the fan, heater tap and a/c thermostat which are cable driven.
The vacuum side of the system is an easy solution as I can run electric vacuum solenoids in place of the current buttons which I assume a Fusion Brain can handle easily as it is just an on/off deal.
With the heater, I was going to run a servo motor connected to a cable that operates the original tap (I'm not sure if FB can control a servo?) I was probably going to use something similar for the a/c thermostat.
I was hoping to use a pwm for the fan although I'm not sure if Fusion braing can handle that sort of current load?
Is Fusion Brain the way to go?
I am more than able to do the graphic side of things, but the programing side of things will be a learning curve.
I am happy to use a centrafuse front end or similar, but I'm not sure how it will look in portrait orientation?
I have search here quite a bit, but seem unable to find any examples of hvac systems operated by the car pc?
Can anyone point me to some examples or are they few and far between?
