Abstract:     A class of transporters for carrying an individual over ground having a surface that may be irregular. Various embodiments have a motorized drive, mounted to the ground-contacting module that causes operation of the transporter in an operating position that is unstable with respect to tipping when the motorized drive arrangement is not powered. Methods of controlling the transporter are described that allow the dynamic behavior of the transporter to more closely match preferences of a rider. These methods include providing preferential responsiveness to change in pitch angles and pitch rates.

Claim     1. A device for carrying a user, the device comprising:

a. a platform which supports a payload including the user,

b. a ground-contacting module, mounted to the platform, including at least one ground-contacting member, characterized by a ground contact region, and defining a fore-aft plane;

c. a motorized drive arrangement, coupled to the ground-contacting module; the drive arrangement, ground-contacting module and payload constituting a system being unstable with respect to tipping in at least the fore-aft plane when the motorized drive is not powered, the system characterized by a pitch angle offset from a specified pitch angle and a pitch rate offset from a specified pitch rate; and

d. a control loop in which the motorized drive arrangement is included, for dynamically maintaining stability of the system in the fore-aft plane by operation of the motorized drive arrangement in such a manner that a drive command supplied to the motorized drive arrangement includes a contribution related to the pitch angle offset multiplied by a first gain wherein the first gain is a function of the instantaneous pitch of the device.
