The paper compares design approaches for achieving a headway control functionality for trucks and busses. The approaches considered are fuzzy logic, Hinfinity, and a strategy based on headway range and its derivative (range rate). For heavy vehicles, the control unit has a number of nonlinearities to compensate for, including full accelerator saturation, engine characteristics, and a limited deceleration capability as may be influenced by rolling resistance. aerodynamic drag, and retarded capabilities. Performance properties of the controllers are derived from simulations of basic operational situations such as closing-in on a preceding vehicle that is traveling at a slower speed or following a vehicle whose speed varies. Finally, it can be said, that the control by objective approach (the 'headway and speed controllers' control) can be generalised for use in many vehicle system dynamics applications. This control is easy to implement once the designer chooses a control objective function.
