Abstract:
1. A method for determining a shift point of an automatic transmission of a self propelled vehicle having an engine controlled by a governor, comprising the steps of: providing a torque sensor operable for sensing actual torque output of the engine and outputting information representative of the actual torque output; providing a control system connected to the torque sensor for receiving the information representative of the actual torque output, the control system being automatically operable for monitoring the information representative of actual torque output in real time during the operation of the engine when the engine is operating under at least one predetermined operating condition and determining a base torque value representative of a maximum available torque of the engine at a specified engine rpm as a function of the monitored actual torque output; and determining the shift point for the automatic transmission as a function of the determined base torque value.
