Abstract
The complexity of designing and implementing a vehicle
electrical control system for ultra fuel-efficient hybrid vehicles
is significantly greater than that of a conventional vehicle. To
quickly demonstrate and iterate capabilities of these vehicles, an
efficient and rapid means for developing requirements, mapping
these into an electrical control and communications architecture,
and developing prototype systems is needed.
The General Motors Precept concept vehicle is an example of an
energy- efficient vehicular control system developed using a
"requirements to software'' development process and
electronic controller infrastructure that demonstrates these
attributes. The Precept is General Motors Corporation's
technology demonstration concept vehicle developed to address
General Motors Corporation's commitment to the Partnership for
a New Generation (PNGV) program.
This paper describes the goals, process, and implementation of
the electronic controls used in the development of this ultra
fuel-efficient hybrid electric vehicle. The process incorporates
vehicle worthy prototyping components, and tools that are flexible
enough to accommodate evolutionary development of control
algorithms.
