Systems and methods for maintaining an industrial lift truck within defined bounds

A system for controlling a lift truck behavior, the system comprising:

• a controller, the controller to analyze at least one of actual and predicted lift truck behavior, and based on the analyzed lift truck behavior, the controller to control at least one lift truck performance parameter;
• the performance parameter controlled to maintain the lift truck center of gravity within a stability map, the stability map to define a three-dimensional range of center of gravity positions that maintain lift truck stability;
• and
• the performance parameter controlled to maintain an intended path of the lift truck within an allowable deviation map, the allowable deviation map defining a two-dimensional envelope of allowable lift truck travel deviation from the intended path of the lift truck.

A system for controlling a lift truck performance parameter, the system comprising:

• an operator input device, the operator input device to provide a command to control at least one of steering and acceleration;
• a controller, the controller to receive the command to control the at least one of steering and acceleration, and the controller to receive a signal of operating conditions, the controller to analyze the command and the signal, and based on the analyzed command and analyzed signal, the controller to control at least one lift truck performance parameter;
• the performance parameter controlled to maintain the lift truck center of gravity within a stability map, the stability map to define a three-dimensional range of center of gravity positions that maintain lift truck stability;
• and
• the performance parameter controlled to maintain an intended lift truck path within an allowable deviation map, the allowable deviation map defining an envelope of allowable travel deviation from the intended lift truck path.
