Active Tilt and Steer Control for a Narrow Tilting Vehicle: Control design and implementation

Nowadays, the problem of the pollution, the cost of the energy, the traffic congestions and the progress in the technology of control systems more recently motivated a new interest in small narrow commuters vehicles for individual mobility. However these kind of vehicles are likely to have reduced stability against overturning during cornering due to the particular geometric with a narrow track width and relatively high center of gravity. This brings about the need for an active control system that ensures the tilt stability or an appropriate leaning during cornering without affecting the handling of the vehicle. Hence, Active Tilt and Steer control tends to be an alternative strategy that combines the action of traditional power steer and tilting actuator acting on the front suspension in order to allows the vehicle stays upright at lower speeds, and at higher speeds allows car-like steering while the vehicle self-leans into the curves like a motorcycle.
