Ebike OS (Operating System) Implementation

[Lyen]

What would you guys like to have if there is such a thing as electric bike operating system exists? I think it would be awesome if ebike has its own OS.

Presumably an ebike OS in any form would build on existing standards (eg available components)

This would be awesome if there were a cycle-analyst on crack kind of thing, which had a large color LCD display. I can think of endless amounts of applications.

-Motor controller feedback, control, on the fly
-Traction control
-all of cycle analyst functions
-logging of all sorts
-remote control/security
-GPS tracking/navigation
-lighting control
-Battery monitoring/charge control


Needless to say this is one of those dreaming threads...

This is the sort of thing I wanted to develop, but am not capable of doing by myself, in threads like this one on LadyAda's forum:

Electric Bike motor, lights, safety features conversion kit

There is more to it than what I posted, but I stopped posting as there was no real interest in developing it. (I have had a couple of people say they wanted to, but never did anything for one reason or another, and another recently that has not replied to me at all).

Here is one being designed and tested. Do you guys like it?

Boost the market by providing a solution for many problems the industry is facing as it grows.
Provide a large vision, think ahead and anticipate future LEV applications and technical requirements.
Provide a communication and developement platform for representatives of different companies and applications in the LEV field to find the best technical solution to connect electric vehicle components.
Define the specifications of the EnergyBus communication and connector standard and thus facilitate the development of high-quality compatible EnergyBus devices
Promote the benefits of EnergyBus and the quality of products that have passed compliance testing.
Promote science and research in this area.
Encourage bicycle OEM‘s, peripheral vendors, software vendors, and other research institutes and associations to join and work actively in the further development and finalization of the EnergyBus system.
Be an authority to ensures that products using EnergyBus have passed compliance testing.
The progress of EnergyBus depends directly on the commitment and input of its members.





Interesting list of Members including BionX, Ultra Motor, Olimpia, Panasonic, Sanyo... and one Partner listed, CAN in Automation e.V. (CiA) noted as "...international users' and manufacturers' group, that develops and supports CANopen and other CAN-based higher-leyer protocols"

These guys seem like a fun bunch... seen here:
http://www.can-cia.org/index.php?id...user%20char%28124%29%3D0%20and%20%27%27%3D%27

"CAN in cars using a single DC power-line for communication"
"One new promising technology offers a unique network communication solution between modules installed in cars using only a single DC power-line (DC-bus). This technology is potentially the network with deepest capability in the world."

and

"The use of DC-bus can become an excellent technology in a short period of time because of the following benefits:
Reduce harness weight
Eliminate complex cabling
Save installation time and cost
Multiple networks can communicate over single Power Line
Messages from the CAN-bus controller are stored in the transmit FIFO
Differential QPSK modulator that drives the noisy line (through a passive filter)
Error correction
Operates over 14-V until 42-V battery line
Selectable channels"

IF anyone here is interested to reverse ingeneer the BionX new CANbus console, i know many person would be interested!!

The guy at the BionX factory said to me that they use a bridge CANBUS-USB commonly known as BIB (Bike interface Box)

I wonder is someone here could extract the code from a console ( I have one new CANbus on my hands now...)

Please let me know!

Yes that would be awefull
It maybe would just be geeky to have but I would like to have a BionX CANBUS sniffer just to play around a bit...
I get my bionx in about two weeks and maybe with some more research and the microchip canbus sniffer it could be possible to slowly reverse engineer the communication.
I'm not sure if it would be possible to read out the rom over the canbus but maybe directly from the uC... maybe buspirate helps

I *really* doubt bionx would program their microcontroller such that it would be readable by conventional methods. What you'll need is to send it to someone in china, fork over a few grand, and wait while they use a laser to knock out the lock bit and/or tap the address/data lines directly inside the chip.

I've always thought it was only in si-Fi movie!!!

is it really fesable???

[amberwolf]

Theoretically, yes, if they know where and how deep to burn to get to the die.

You can find some information on popular ways of attack at http://www.break-ic.com/topics/break-ic.asp .

Here's a company that apparently specializes in stealing firmware: http://break-ic.com/faq.asp

I dont think Microchip would them make custom versions of theire normal product and then They just burned the readwritefuse and as we all know there where ways to break trough this security and get into the chip without the hardcode method.

@Doctorbass Thats usually the hardcode way and just interesting for people that have the money or access to special machines.
But this is the way usually hardware security like the RSA tokengens can be (has been with the old Version) broken but it need a lot of time, a good laser, a very good electron microscope and of course deep knowledge about howto reverse engineer the traces on all the layers.

Also let's not forget that we need WIRED to anounce that you can now run doom on a bike. And to control the player you gotta ride and honk to shoot. Not recommended for use on busy streets
