Extending Technology to Drive By Wire Control

This paper highlights the development of a full authority electronic drive control system (commonly termed “drive-by-wire”). The system is designed to operate within the larger integrated vehicle electronic system (vetronic) architecture established for ground vehicles. It employs a number of modes which control the vehicle dynamics, track tension, suspension, and ride qualities.

Through a dual-redundant computer architecture, drive-by-wire (DBW) affects all aspects of the vehicle dynamics, control, and mobility. One of the most significant aspects of this control system is it's capability to alter the maneuverability and handling qualities of the vehicle through dynamic compensation. DBW control laws provide improved stability and shape the driver control commands through active feedback. The vehicle's augmented dynamics significantly extend the performance capabilities as well as enhance the safety characteristics.
