Review of in-car Telematics box

Hello,

Our company has developed an in-car telematics "black box" that comprises of a custom PCB mounted on top of a linux-based computer. Actually it is three layers - the linux computer, a combined GPS/3G board and finally our board.

Our board is primarily responsible for control of the car. i.e. lock/unlock doors, toot the horn, detect if door is open/closed, detect if ignition is on. The electronics board is essentially an interface between the car and the linux GPIO pins.

There is a wiring harness which terminates at a connector on our board, with the various wires of the harness wired into the car's electrical system by an auto electrician.

This project is for an electronics specialist - with automotive experience - to review the board we have built and suggest changes (and make the changes in Eagle).

In particular:

1. Are the components we have specified appropriate for a harsh automotive environment? i.e are they too delicate?

2. It may be necessary to add extra components, say for protection, floating inputs, etc. Our electronics designer has a limited amount of training and whilst we have a working prototype, we are unsure if it would survive for very long 'out in the field'.

3. Make suggestions, improvements and changes directly in the Eagle file so we can order a new set of test boards.

In summary we have a working prototype but it needs review and 'toughening up' before we would release a batch into our customer's cars.

Please, only professionals with in-car electronics experience (automotive electronics) should apply. For example, extreme hot/cold inside the car, moisture such as breath, vibrations, electrical noise, surges, power drops on engine cranking, etc.

Any questions, please let me know.
