Abstract
A patient transport apparatus for transporting a patient over a floor surface is described herein. The patient transport apparatus includes a throttle assembly, an auxiliary wheel assembly including an auxiliary wheel, an auxiliary wheel drive system, and a control system for operating the auxiliary wheel drive system based on user commands received from the throttle assembly. The control system includes a controller configured to detect a position of the throttle assembly, determine a desired rotational speed value associated with a current operating throttle position, determine a current rotational speed of the auxiliary wheel, select an acceleration rate based on the current rotational speed of the auxiliary wheel, generate an output signal based on the selected acceleration rate, and transmit the generated output signal to the motor control circuit to operate the motor to rotate the auxiliary wheel at the selected acceleration rate.
