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.
