Control of a limited slip differential for a vehicle

A method of controlling a limited slip differential (LSD) of a vehicle, the vehicle having an engine and left and right ground-engaging elements, the vehicle having the LSD operatively connectable to a driveshaft and to the left and right ground-engaging elements, left and right suspension assemblies connected to the left and right ground-engaging elements, the LSD being adapted for transferring torque from the driveshaft to the left and right ground-engaging elements, the method comprising:

• receiving, by a control unit operatively connected to the LSD, sensor signals from at least one sensor of at least one parameter indicative of one of:
• an extension position of at least one of the right and left suspensions, and
• a vertical position of at least one of the right and left ground-engaging members;
• generating, by the control unit, a control signal at least partly based on the sensor signals;
• and
• controlling, by the control unit, selective locking of the LSD based on the control signal.

A control system for determining a traction quality of a vehicle,

• the vehicle having an engine and left and right ground-engaging elements, left and right suspension assemblies connected to the left and right ground-engaging elements,
• the control system comprising:
• at least one sensor of at least one parameter indicative of positions of one of:
• the right and left suspensions, and
• the right and left ground-engaging members;
• and
• a control unit operatively connected to the at least one sensor, the control unit being configured to execute:
• receiving sensor signals from the at least one sensor;
• determining a value of at least one of:
• a positional difference between at least one of the right and left suspensions and the right and left ground-engaging members, and an average position of at least one of the right and left suspensions and the right and left ground-engaging members;
• and
• generating a control signal representative of the traction quality of the vehicle at least partly based on the value.
