摘要： The present invention relates to a controller (60, 160) for estimating traction. The controller (60, 160) comprises a monitoring module (66) monitoring torque values; a determining module (68) determining a maximum torque value (100) by obtaining and storing empirical data while driving on a surface, the maximum torque value (100) being the torque immediately prior to wheel slip; a predicting module (70) predicting a traction threshold (102) based on the maximum torque value (100); and a control module (72) outputting a signal indicative of traction threshold (102).
