Draw bar force sensing locomotive control system

A locomotive control system comprising:

• a locomotive frame;
• a locomotive draw bar coupled with said locomotive frame for providing coupling capabilities with other rail cars;
• a locomotive draw bar force sensor, operatively associated with said locomotive draw bar, for generating force signals;
• a locomotive engine generator coupled with said locomotive frame, for generating electric power;
• a locomotive engine generator sensor coupled with said locomotive frame and said locomotive engine generator for generating locomotive engine generator signals which correspond to the locomotive engine generator output;
• means for monitoring said force signal and said generator signal and issuing a command signal to said locomotive engine generator to operate the locomotive engine generator at a level having the locomotive engine generator signal which corresponds to the maximum of said force signals;
• and
• a traction motor interconnected with said locomotive engine generator capable of receiving electrical power from said locomotive engine generator for causing rotation of at least one locomotive wheel;
• whereby said locomotive draw bar force sensor detects strain within said draw bar and generates a sensing signal corresponding to the draw bar strain which is supplied to the means for monitoring, where trend information is compared and the command signal is generated for manipulating the operation of the locomotive engine generator at the locomotive engine generator level which corresponds to the maximum of said force signals from said draw bar force sensor;
• thereby, maximizing the draw bar force.
