A concept for implementing headway for commercial vehicles is introduced. Developing a headway system is motivated by the desire to improve safety and enhance mobility through the use of longitudinal control. Such control is carried out via two possible modes of operation: cruise control mode and headway control mode. The headway control system consists of range and range rate sensors, a cruise control capable of accepting velocity commands and a control unit using a heuristic algorithm for determining the appropriate mode of operation and for selecting that mode. When in a headway control mode, the system utilizes information from the range and range rate sensors to maintain a prescribed headway from a leading vehicle. When in a cruise control mode, the system maintains the speed selected by the driver. The equations of motion that mathematically represent the vehicle are derived, and a system model for simulation is constructed. An analysis by simulation is performed to demonstrate that reasonable performance of the system can be expected.
