A vehicle stabilising system and method of operation thereof

A system for stabilizing a vehicle, the system comprising:

• a plurality of sensors that comprises a position sensor to determine a vehicle speed, an angular displacement sensor to determine a roll angle corresponding to an angular displacement of the vehicle in a roll direction and a roll rate corresponding to an angular velocity of the vehicle in the roll direction, and a steering torque sensor to determine a steering torque applied to a steering handle of the vehicle;
• and
• a stabilizing unit coupled to the plurality of sensors, wherein
• the stabilizing unit:
• determines a synthesized torque based on the roll angle, the roll rate, and the vehicle speed;
• determines a tuning parameter based on a comparison of the synthesized torque and the steering torque;
• determines a stabilizing torque based on the tuning parameter and the synthesized torque;
• and
• provides, to an actuator, an actuating signal corresponding to the stabilizing torque for applying the stabilizing torque to the steering handle of the vehicle for stabilizing the vehicle.
