New console design - Carputer, Climate, and One-touch Window

[hans14914]

I posted over on Rennlist, but neglected to post an announcement over here. I am working with Paul Champagne on redesigning the layout for the console, modernizing it both in appearance and function.

The frames and brackets are all complete now, window switches have been designed and are out for bid, and the hardware portion of the climate is in place (working on software and alternate layouts/interface options).

Below is a copy of the initial post of the Rennlist thread, and then some pictures of the current and final design (for the "deluxe" version with OLED climate display).

A working version should be on display at SITM this year. On the photos, please note that this is a mock-up as the button PCBs haven't been manufactured as the backlighting layout was just finalized last night. The buttons and knobs are being held on by tape. Also, there will be a decorative overlay covering the entire panel in several choices of material, including leather. In the final version, most of the clear acrylic will not be visible. More information is in the Rennlist thread, as well as development pictures.

Thanks,
Hans

"In an attempt to modernize the 928, I have elected to tackle revamping the console, both cosmetically and electronically. This has been done in several parts, and all will be available through our friendly dealer network shortly. The currently planned offerings are as follows:

* In-car computer system
* Re-designed climate control interface (with PC control functionality)
* “Lifetime” quality one-touch window switches
* Redesigned console insert to hold all the above items in a seamless flat face


Here are some more details for each respective element:

928 Carputer

* 7” touchscreen monitor – available in several sunlight rejecting configurations, including a full optically bonded transflective option.
* 8 dedicated/programmable feature buttons
* Dedicated volume knob with push-to-mute function
* Capacity to carry up to two 2.5” hard drives
* Bracket will accept any standard mini-ITX motherboard
* Mounting provisions for either M2 or M3-ATX power supplies


The system installs in a stock 928 console with no permanent modification or drilling required. The entire console can be returned back to stock at any time. All computer components are installed inside the console, and requires no remote mounting of components (with the exception of GPS and wifi antennas if required).

I am recommending Windows for the OS for compatibility with Sharktuner and Theo’s diagnostic tool. There are several existing interface options, with the leaders being Centrafuse and RideRunner. Centrafuse will be an optional pre-loaded software (should you chose not to assemble the unit yourself), but RideRunner is a fantastic “open-source” non-comercial option, that can not be preinstalled, but certainly a worthy competitor to the commercial Centrafuse offering.

Revised Climate Control Module

* Modular design for easy customization of faceplate
* All interface voltages can be 5v for use with optical rotary encoders (improved lifespan)
* Can be controlled by microcontroller, or PC with appropriate software
* 100% variable speed control with PWM module implementation (optional)
* Discrete actuation of vent selection (all vents can be selected independently)
* Discrete actuation of defrost option
* Discrete actuation of recirculation option
* AC button relocated to climate module
* Direct plug-in using existing harness


The climate control module currently is designed for use with the new console insert, but drawings are prepared for a stock replacement version as well. This board uses the same card-edge as the factory unit, and plugs into the existing wiring. No provisions have been added at this time for the rear AC – although they have been considered and may be implemented before production. This is because there is no factory integration between the rear ac and front climate, or even any real temperature control. Proposed integration for now would be to toggle the rear AC on when MAX-COOL is selected on the front controller.

Window Switches
Several years ago, we were tempted by the option to have a modern window switch system. This system is still under development, and as not to compete directly with it, I have decided to look at this in a new way. I have identified the best switches possible for use in an automotive environment. They been successfully tested to many millions of actuations, and use a magnetic field to provide the click feedback and minimized contact wear. These will never need to be replaced (under normal operation), and will always have a consistent click, as there is no spring to wear out.
Another feature is that these can be backlit, and also for those with custom interiors, they are easily covered in leather.

I have also included a dedicated rear hatch release button to the opposite side of the wiper. Using this option will require adding a wire underneath the seat (and will obviously only work on cars with power hatch releases).

To give the switch panels their intelligence, and also not to infringe on the intellectual property of fellow rennlisters, I have chosen to recommend installing with DEI brand window modules: 530T for windows, and 529T for sunroof.

These are proven, with millions in current installation, they tie into any aftermarket alarm very easily for roll-up on arm, vent with aux button…. Etc. They also add one-touch functionality, as well as many other features. In the even that a unit would fail, it would be covered under DEI’s warranty, and require a simple plug and play swap. If out of warranty, the units are readily available on ebay for under $60 every day of the week.

Console insert
To hold the all the new components, I had to come up with a new faceplate. This new design gives a nod to the current trends in automotive design. The ashtray is removed in favor of a catch-all tray, and there are no-longer any seams in-between the various components. There are also no visible fasteners of any kind.

The frame can be covered with any laminate desired, or finished in leather, wood, or metal to suit your own personal tastes.

I have been working with Paul Champagne on this project, and he will be providing the aesthetic treatments for all the above. If you have any specific questions regarding functionality, I would be happy to answer them. For the cosmetics, please address Paul.

Looks very nice. I see the HVAC Controls gone or Altered? Will this serve the early OB Guys too? Or is this just for the later S4's and above?

What material is the final plate will be used? Or is that Black Material it with Champagnes Touches?

Radically re-designed console (Carputer, Climate, and one-touch windows) - Rennlist Discussion Forums

Currently, I am only able to do the 84+ Climate, as all models beyond then are arguably the same (small differences easily encompassed in a single board). I dont have easy access to an OB car for testing, so it will be a while before I can even consider something for them. I am planning on working on a similar setup that retains the stock climate, which should be compatible with OB cars.

Thanks,
Hans

Very nicely done! Keep up the good work.

N!

PS: Where is the stereo head unit?

This works as a replacement stereo unit - with lots more features.
