Methods and Apparatus for Moving a Vehicle Up or Down a Sloped Surface
First Claim
1. A system for safely moving a vehicle up or down a sloped surface while in a sloped surface mode of operation, comprising:
- at least one ground contacting element for moving the vehicle on the sloped surface;
a propulsion system providing an amount of torque to the at least one ground contacting element to prevent the vehicle from uncontrollably moving down the sloped surface while in the sloped surface mode of operation;
an assist mechanism coupled to the propulsion system to enable an operator to guide the vehicle.

Abstract
A system and method for safely moving a vehicle up or down a sloped surface is provided. In one embodiment, a method involves operating the vehicle in a sloped surface mode when at least one ground contacting element for moving the vehicle is on the sloped surface. An amount of torque is provided to the at least one ground contacting element to prevent the vehicle from uncontrollably moving down the sloped surface while in the sloped surface mode of operation. An assist mechanism can be coupled to the propulsion system to enable an operator to guide the vehicle.
