Torque Compensation Method and System

A system for adjusting output torque of an engine for a motor vehicle including a torque compensation system, comprising:

• an electronic control unit;
• a first sensor for detecting a rotational speed of a first shaft in a drive train of the motor vehicle, the first shaft being an input shaft;
• a second sensor for detecting a rotational speed of a second shaft in the drive train of the motor vehicle, the second shaft of the motor vehicle being an output shaft hydraulically coupled to the first shaft;
• and
• a temperature sensor for determining a vehicle fluid temperature;
• wherein the electronic control unit is configured to calculate an actual slip ratio based on a measured speed from the first sensor and a measured speed from the second sensor;
• wherein the electronic control unit is configured to determine an expected slip ratio based on a measured vehicle fluid temperature from the temperature sensor, wherein the expected slip ratio is determined based on a correlation between the vehicle fluid temperature and the expected slip ratio stored in a database in communication with the electronic control unit;
• wherein the electronic control unit is configured to determine whether the actual slip ratio between the first shaft and the second shaft exceeds the expected slip ratio corresponding to the measured vehicle fluid temperature;
• wherein the electronic control unit is further configured to retrieve a number of times the torque compensation system has been activated in a current driving cycle;
• and
• wherein the electronic control unit is configured to deactivate the torque compensation system if the number of times the torque compensation system has been activated in the current driving cycle exceeds a predetermined number of activations.
