How the Segway PT Works (cont.)
Slow Speed Roll Compensation Feature
The PT utilizes a feature called Roll Compensation that separates steering
input from terrain changes. This allows the rider to ride in a straight line
over uneven terrain by keeping the LeanSteer Frame oriented straight up
and down. When riding at low speeds and on slopes, Roll Compensation
is reduced, allowing for more precise control at slow speeds as well as
reducing steering drift during power on. As the rider's speed increases, Roll
Compensation increases, as well.
Beginner Setting Mount/Dismount Feature
The Segway PT LeanSteer technology was designed to provide responsive
steering. The software includes a feature to help new riders easily learn
how to mount and dismount the PT without unintentionally initiating a turn.
When the PT is in Beginner Setting and the rider has less than two of the
four Rider Detect Sensors (see "Rider Detect Sensors," p. 33) engaged, and
the PT is moving neither forward or backward, the sensitivity of the LeanSteer frame is 15% of normal operation. When the PT is in Beginner
Setting and the rider has two feet on the PT, and the PT is moving neither forward or backward, the sensitivity of the LeanSteer frame is 55%
of normal operation. As the PT's speed increases, the sensitivity of the LeanSteer frame is gradually increased.
NOTE:
The Beginner Setting Mount/Dismount Feature is only activated when the PT is in Beginner Setting (turtle icon displayed on Infokey Controller).
For more information on switching between Beginner Setting and Standard Setting, see "Beginner Button Functions," p. 43.
