Electronic Stability Control of a Narrow Tilting Vehicle 2011-01-0976

This paper aims to contribute to the development of an electronic stability control for narrow, fully tiling vehicles with handling and stability characteristics similar to motorcycles, and to improve the understanding of the driver-vehicle interaction. To allow for high energy efficiency of the control system, mainly steering torque is applied to stabilize and tilt the vehicle. The dynamic properties of the specific investigated vehicle suggest high demands to a driver without an appropriate control system. To allow for automobile-like operation of the steering wheel, the motion of the steering wheel and the steering system of the front wheel has been decoupled, and a steer-by-wire system has been developed. Both simulations and field tests with a prototype proved proper performance of the electronic stability control, but also revealed the need of an automobile driver to adapt to this kind of vehicle when operating it even with the control system.
