    Abstract: A utility vehicle includes a frame, a power source, and a plurality of steerable structures. Ground engaging members are connected to the steerable structures. An operator seating area includes a steering control and a speed control. Controllers receive input from the steering control and the speed control. Motors drive the ground engaging members at different speeds and in different directions. A controller integrates a steering input with a speed input to effect rotation of the steerable structures and effect rotation of the ground engaging members. The steering control, speed control, controllers, steerable structures, and motors are configured to work together to control the rotational speed of all of the ground engaging members based upon a steering angle input and the lateral side the ground engaging member is connected to. Other examples include braking mechanisms, adjustable track width, and a sealed tubular frame.

    Abstract: A lawn maintenance vehicle includes an adjustable seat assembly, wherein the seat assembly is rotatable relative to a frame of the vehicle when the vehicle is operated on a sloped surface. The seat assembly is rotatable in order to maintain the operator in a substantially vertical seated alignment while operating the vehicle on a sloped surface. The seat assembly is also rotatable when the vehicle is in a zero-turn or tight-turn maneuver, wherein the seat is rotated toward the center of turning radius to offset the centrifugal forces experienced by the operator during such a maneuver.

    Abstract: Systems and methods for drive and steering control in a drive-by-wire system for outdoor power equipment are discussed. Various embodiments can employ techniques related to one or more of: steering based on actively steered wheels with zero caster trail, variable output damping of vehicle control outputs, steering that compensates for drive system loss, emulation of drivability of a hydrostatic drive system by a non-hydrostatic drive system, employing a floating neutral point to improve steering on slopes, open loop techniques for hill holding and speed compensation on hills, and/or adjustment of a speed range associated with control inputs.
