Vehicle stabilising system and method of operation thereof

Abstract

A system includes: sensors that includes 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 sensors. 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 an actuating signal corresponding to the stabilizing torque for applying the stabilizing torque to the steering handle of the vehicle.
