A dual architecture approach for vehicle communication control: An accommodated device gateway and intelligent data bus, signal circuitry analysis and message security protocols

The design cycle for a consumer electronic device or accommodated device (AD) is between 9 and 18 months; The design cycle for a vehicle is approximately 3 years; The life cycle for a consumer electronic device is normally 2 years and for a vehicle is at least 6 years, therefore there is a mismatch between the two designs and life cycles. A car bought today is inevitably equipped with old electronic technology in some cases obsolete.; This dissertation deals with a solution to allow the latest and most advanced consumer electronic technology to be used in a seamless way, in vehicles equipped with an Accommodated Device Gateway and an Intelligent Data Bus.; The Accommodated Device Gateway (ADG) is a microprocessor responsible for handling the in/out-vehicle communication and control signaling. The ADG is a gateway between the vehicle and aftermarket devices, that customer chooses to bring to the vehicle (i.e. cell phones, navigation devices, MP3 players, etc.). The ADG will convert IDB-C messages to vehicle bus messages and vice verse, and provide a firewall to the vehicle electrical system and restrict access to proprietary or unauthorized vehicle information.; The Intelligent Transportation System Data Bus Controller (IDB-C), is a serial data link, based on Controller Area Network (CAN) protocols; it functions as the vehicle local area network handling the signal traffic and protocols at optimized speed of 250 Kilobits per second (KBPS). The IDB bus is a non-proprietary token passing bus, designed to allow disparate consumer, vehicle and commercial electronic components to communicate and share information across a standard, open data bus; it is a truly plug-and-play architecture where devices graciously join or leave the bus, without disrupting the normal bus operation.; My specifics contributions to the design, development and implementation of this technology are: (a) Developed the business model, based on clinics to targeted customer areas addressing their needs and the willingness on the price to pay. (b) Create the design specifications for the ADG functioning, specifically the Power Mode, Translation State Tables, and the Security Communication Protocols. (c) Design the hardware model using MicroSim Pspice Advanced software for modeling and simulation. (d) Worked very closely with two companies on creating Proof of Concept hardware models, at two revision levels. (e) Worked very closely with experts, on specialized testing and measurement labs on Electromagnetic Compliance for the ADG and the IDB bus hardware.
