CONTROL OF A PERSONAL TRANSPORTER BASED ON USER POSITION
First Claim
1. A method for controlling a transporter, the transporter having at least one ground-contacting element and a controller operatively communicating with the at least one ground-contacting element, the method comprising:
- receiving, by the controller, a desired yaw and a desired yaw rate, the desired yaw and the desired yaw rate being based on a body orientation of a load on the transporter;
computing, by the controller, a desired direction of motion of the transporter based on the received desired yaw and the received desired yaw rate;
receiving, by the controller, a pitch of the transporter;
computing, by the controller, a pitch command signal based on the pitch;
computing, by the controller, a command signal based on the desired direction and the pitch command signal; and
providing, by the controller, the command signal to maintain balance of the transporter and motion in the desired direction.

Abstract
An apparatus controller for prompting a rider to be positioned on a vehicle in such a manner as to reduce lateral instability due to lateral acceleration of the vehicle. The apparatus has an input for receiving specification from the rider of a desired direction of travel, and indicating means for reflecting to the rider a propitious instantaneous body orientation to enhance stability in the face of lateral acceleration. The indicating may include a handlebar that is pivotable with respect to the vehicle and that is driven in response to vehicle turning.

11. A system for controlling a transporter, the system comprising:
-
at least one ground-contacting element; and a controller operatively communicating with the at least one ground-contacting element, the controller including; receiving a desired yaw and a desired yaw rate of the transporter, the desired yaw and the desired yaw rate being based on a body orientation of a load on the transporter; computing a desired direction of motion of the transporter based on the received desired yaw and the received desired yaw rate; receiving a pitch of the transporter; computing a pitch command signal based on the pitch; computing a command signal based on the desired direction and the pitch command signal; and providing the command signal to maintain balance of the transporter and motion in the desired direction. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
