In this paper, a multi-model observer dedicated to ATV (All-Terrain Vehicle) rollover prevention is proposed. Beyond the stability estimation thanks to an observer, the main contribution of this paper lies in the independent reconstruction of front and rear cornering stiffnesses to describe the vehicle dynamics, with a low cost sensing equipment. This advance allows to take into account the two main...
In this paper, an ATV (All-Terrain Vehicle) rollover prevention system is proposed. Dynamic instability evaluation is based on the on-line estimation and prediction of the Lateral Load Transfer (LLT) from a vehicle model based on two 2D representations. As off-road vehicles are considered, grip conditions have a large influence. They are here estimated relying on observation theory. Nevertheless,...
Rollover is the principal cause of serious accidents for All-Terrain Vehicles (ATV), especially for light vehicles (e.g. quad bikes). In order to reduce this risk, the development of active devices, contributes a promising solution. With this aim, this paper proposes an algorithm allowing to predict the rollover risk, by means of an on-line estimation of a stability criterion. Among several rollover...
