Highway platooning of vehicles has been identified as a promising framework in
developing intelligent transportation systems. By autonomous or semi-autonomous
vehicle control and inter-vehicle coordination, an appropriately managed platoon can
potentially offer enhanced safety, improved highway utility, increased fuel economy,
and reduced emission. This thesis is focused on quantitative characterization of impact
of communication information structures and contents on platoon safety. By
comparing different information structures which combine front sensors, rear sensors,
and wireless communication channels, and different information contents such
as distances, speeds, and drivers' actions, we reveal a number of intrinsic relationships
between vehicle coordination and communications in platoons. Typical communication
standards and related communication latency and package loss are used
as benchmark cases in our study. These findings provide useful guidelines for information
harmonization module (IHM) design in sensor selections, communication
resource allocations, and vehicle coordination. Two new weighted multi-information
structure control and information data rate control are proposed. Both control methods
have been validated by experimental simulation and finite element analysis, and
also show a surprising improvement of communication resources usage with data rate
control. The results for the proposed module are new in the literature for vehicle
platoon control. A new method is introduced to enhance feedback robustness against
communication gain uncertainties. The method employs a fundamental property in
stochastic differential equations to add a scaled stochastic dither under which tolerable
gain uncertainties can be much enlarged, beyond the traditional deterministic
optimal gain margin. Algorithms, stability, convergence, and robustness are presented
for first-order systems. Extension to higher-dimensional systems is further discussed.
Simulation results are used to illustrate the merits of this methodology.
