The role of dynamics and control in cutting vehicle CO
2
emissions
T
here are only two ways of cutting CO
2
emissions from road vehicles: either i) by eliminating carbon from the
propulsion source, or ii) by dramatically improving vehicle efficiency. Adopting either of these options affordably
is by far from easy. This plenary lecture will focus on areas of vehicle technology where dynamics and control can be
used expediently to improve vehicle efficiency for conventionally powered vehicles, Hybrid Electric Vehicles (HEV), and
(battery) Electric Vehicles (EV). For example, in both conventionally-powered vehicles, and HEV, there are significant
benefits of closed-loop combustion control to improve engine thermal efficiency and performance using different fuels.
The state of indirect cylinder pressure sensing will be discussed. Another application where significant fuel economy
improvements are possible in IC engines, is to replace the liquid cooling with evaporative cooling a novel approach to
control two-phase spray evaporative cooling will be outlined. Yet another area for CO
2
emission reduction for HEV is
the adoption of advanced Range Extender concepts. And a final example (where a novel optimal control approach will
be discussed) is optimal flywheel-based kinetic energy recovery that offers durable vehicle range extension for both EV
and HEV. In summary, a broad overview will initially be given of areas where dynamics and control alone can engender
significant improvements in vehicle efficiency. Some of the realizable benefits and implementation challenges will be
examined for the topics mentioned.
