Abstract:
A system for balance a two-wheeled vehicle when approaching rest or when at rest comprising:a gyro rotor; a motor for spinning the gyro rotor; a tipping sensor for sensing tipping of the vehicle; a precession means for precessing the gyro rotor from a non-precessed position to any of a plurality of precessed positions and for facilitating the return of the precessed gyro to the non-precessed position; a controller coupled to the tipping sensor and precession means and for receiving information relating to the velocity of the vehicle, wherein the controller controls the precessions means, wherein the precession means precesses the gyro from the non-precessed position to a precessed position when the tipping sensor has sensed tipping and when the velocity of the vehicle is not greater than a predetermined minimum velocity, and immediately returns the gyro rotor to the non-precessed position.
