Method and sensor arrangement for determining an adverse condition of a powertrain

A computer program product stored on a non-transitory computer-readable medium, said computer program product for determining an adverse condition of a powertrain arranged in a vehicle, where the powertrain comprises one or more shafts, wherein said computer program product comprising computer instructions to cause one or more computing devices to perform the following operations:

• determining angular displacement between angular positions of one or more shafts of the powertrain at individual points along the powertrain;
• determining, based on the angular displacement, an adverse condition of one or more parts of the powertrain, wherein the adverse condition is associated with a torque of the powertrain indicated by the angular displacement;
• and
• performing an action based on the determined adverse condition.

A sensor arrangement for use in a vehicle comprising a powertrain, the arrangement comprising:

• a plurality of angular position sensors arranged to measure angular positions of one or more shafts of the powertrain at individual points along the powertrain;
• and
• a control arrangement configured to:
• determine angular displacement between angular positions of one or more shafts of the powertrain at individual points along the powertrain;
• determine, based on the angular displacement, an adverse condition of one or more parts of the powertrain,
• wherein the adverse condition is associated with a torque of the powertrain indicated by the angular displacement;
• and
• perform an action based on the determined adverse condition.
