1. A patient support apparatus comprising:
a support structure including a base and a frame;
a support wheel coupled to the support structure;
a drive system including a drive member coupled to the support structure to influence motion of the patient support apparatus over a floor surface, and a motor coupled to the drive member;
a user interface including a throttle assembly positionable between a neutral throttle position and a plurality of operating throttle positions; and
a control system coupled to the user interface and the drive system for operating the drive system, the control system including a memory device configured to store a plurality of transition profiles, wherein at least one of the plurality of transition profiles represents a transition over an inclined floor surface, and a processor coupled to the memory device and configured to:
sense movement of the drive member relative to the support structure,
compare movement of the drive member with the plurality of transition profiles, and
determine that the patient support apparatus is traveling on an inclined floor surface.
