In this paper, dynamics and stability of an articulated vehicle in the yaw plane are examined through analysis, simulations, and vehicle testing. Control of a vehicletrailer combination using active braking of the towing vehicle is discussed. A linear analytical model describing lateral and yaw motions of a vehicle-trailer combination is used to study the effects of parameter variations of the ...

Considering driving safety and comfort, this paper proposed a roll and yaw integrated control method utilizing four wheel steering based on disturbance observer (hereinafter DOB) and 2-degree-of-freedom (hereinafter 2DOF) control approach. Firstly, vehicle model for controller design as well as the desired roll and yaw motion were explained; then the controller design was carried out based on t...

To improve safety on commercial cars, a multivariable Global Chassis Controller (GCC) design, involving braking and steering systems is proposed. In case of emergency (e.g. loss of manoeuvrability), the GCC uses the braking system to handle the problem. But, in case of inefficiency of the braking system (e.g. due to low road adherence, large yaw rate error or actuator failure), detected by a br...

This paper presents the findings of the first stage of a fundamental study of the tilt control problem. A tilting railway vehicle is described via appropriate modelling and a frequency domain analysis illustrates the problems associated with straightforward feedback control. A Kalman-Bucy filter is developed based on 3 inertial measurements (body lateral acceleration, roll and yaw rate) to prov...

In this paper, a predictor is developed in order to estimate roll angle and lateral acceleration for tractor-semitrailers. Based on this prediction, an active control system is designed to prevent rollover for these vehicles. In order to develop this control structure, a high order recurrent neural network is used to model the unknown tractor semitrailer system; a learning law is obtained using...
