What do I need to build a COMPLETE Energy Management System for a Vehicle?

Hi everybody,

I'm very new in this electronic world, concrtely in DSP's. My problem is the following: I have to BUY for my company the components needed to build a system which have to:

- To listen to from a CAN bus the signals of around 10 ECU's

- To know how much is the Energy consumption required by everyone

- To select if I let each one to work or not, depending on the power suppliers state

I guess it's necessary:

- A CAN transceiver (SN65HVDx)

- A CAN Controller (TMS320LFx, TMS320F28x, TMS470x, TMS320C24x, TMS320C28x)

The problem is that I really don't know if I would need anything else (ROM memory, Power Supplier) or there is ANY ENCAPSULATE that have my whole requirements.

 

Thank you so much and sorry for my English.

    hello Fernando

    I am not sure if you are looking for design suggestions or ideas on what to look for in a system specification. If you are planning to design this system from ground zero then of course you will need detail technical information on each item of your system. In that case you will also need to think about software /firmware development as all these controllers will need a decent level of software development. If you dont have a design team for this project then you may look for external 3P for development. On the otherhand if you are looking for specification so that you can evaluate 3P solutions for your project then please post detail information on what you need or aiming for. One quick comment - for a new project it will be better if you start with the latest device family like 28x instead of 24x.

    Hello Arafeen,

    First of all, thank you so much for the answer.

    What I'm looking for is to know which alternatives I have to design this system.

    In other words, I have a whole vehicle with its different ECU's inside interconnected by a Bus CAN and I have to get another system also connected who listen and writes in this Bus CAN orders (CAN Data Frames) to manage the power distribution, all based in a control logic which I guess I would have to load in any Flash/ROM memory.

    I'm looking for the differents options:

    - Preferably any complete solution like any ezDsp+Firmware/Software I could use for this

    - Or a list of elements that I need: CAN Transceiver (SN65HVD1050Q for example), CAN Controller (Microcontroller TMS320C28x), and the rest of elements that would be necessary.

     

    If you or anybody else could help me, I would be grateful the rest of my life :)

    Hello Fernando - Most of the CAN specific examples if not all are related to device level programming, something like driver implementation. These examples will help you to understand how the device works , how to program CAN and other peripherals but they don't show high level protocol implementation. May be someone in this forum will provide you the correct reference or you can also try the 3P names Chris provided earlier. Good luck.
