Abstract
A small radius- or zero radius-turn vehicle that may be steered by differentially-driven rear drive wheels and by at least one electronically-controlled, steerable front wheel. A device, e.g., one or more levers, may be provided that controls both speed and direction of the drive wheels. A sensor may be provided that detects a position of the lever(s). A controller may calculate a steering angle of the front wheel based upon the position, and issue a command to an actuator associated with the front wheel. The actuator may rotate the front wheel to an electronically calculated steering angle in response to the command.
