Speed ratio based governor selection

A system for a work vehicle with an internal combustion engine, comprising:

• a torque converter coupled at one end to the internal combustion engine and at an opposite end to a transmission via at least a transmission input shaft,
• at least two governors coupled to the internal combustion engine, wherein the at least two governors are configured to adjust an operating parameter of the internal combustion engine;
• and
• a vehicle control unit communicatively coupled to the at least two governors wherein the vehicle control unit is configured to receive a first and second speed signal, and wherein the vehicle control unit commands an engine control unit to enable at least one of the governors when a ratio of the first speed signal to the second speed signal exceeds a first predetermined threshold, wherein the vehicle control unit is further communicatively coupled to a boom wherein the vehicle control unit receives a signal representative of a boom speed and inhibits the torque converter from operating in a lockup mode when a boom speed signal is above a calculated threshold
• wherein the torque converter operates in the lockup mode when the torque converter couples the internal combustion engine directly to the transmission and otherwise operates in torque converter mode.

A system for improving a perceived ease of operation in a work vehicle with an internal combustion engine, comprising:

• a torque converter coupled at one end to the internal combustion engine and at an opposite end to a transmission via at least a transmission input shaft;
• an all speed governor configured to adjust an internal combustion engine speed when the all speed governor is in an enabled state;
• a torque governor configured to adjust an internal combustion engine torque when the torque governor is in the enabled state;
• and
• a vehicle control unit communicatively coupled to the transmission input shaft and the internal combustion engine wherein the vehicle control unit receives a first speed signal representative of a transmission input shaft speed and a second speed signal representative of the internal combustion engine speed, and commands an engine control unit to enable the torque governor when a ratio of the first speed signal to the second speed signal exceeds a first predetermined threshold.

A method for a work vehicle with an internal combustion engine, the method comprising:

• generating a first signal representative of a transmission input shaft speed and generating a second signal representative of an internal combustion engine speed
• transmitting the first and second signal to a vehicle control unit
• receiving the first and second signal by the vehicle control unit
• analyzing a ratio of the first signal to the second signal by the vehicle control unit, and
• commanding an engine control unit to enable a torque governor when the ratio of the first signal to the second signal exceeds a first predetermined threshold, and when a rate of change of the ratio of the first signal to the second signal exceeds a second predetermined threshold.
