Aiming at the lateral stability control problem of distributed driven electric vehicles under high speed steering condition, a hierarchical algorithm direct yaw moment is designed. The upper takes 2-DOF vehicle model as reference and uses sliding mode to obtain required by tracking desired velocity side-slip angle. lower optimizes distribution four wheel torque with minimum tire utilization rat...

Lane keeping control technology can improve driving safety. But the direct torque, caused by four in-wheel motors of an electric vehicle driven (EV-DFIM), will affect lateral stability. For solving this issue, a two-degree-of-freedom (2DOF) dynamic model EV-DFIM lane system is constructed to obtain stability state equations. Then homogeneous domination-based observer and output feedback control...

Over the last few decades, congested traffic network have become a serious problem in many countries. Congestions result in time losses, increase of fuel consumption and also raise the risk of accidents. Intelligent transportation systems may contribute to mitigate such problems. Advancement together with the reduction in cost of embedded computing, on-board vehicle sensors and wireless communi...

the directional response and roll stability characteristics of a partly filled tractor semi-trailer vehicle, with cylindrical tank, are investigated in various maneuvers. the dynamic interaction of liquid cargo with the tractor semi-trailer vehicle is also evaluated by integrating a dynamic slosh model of the partly filled tank with five-degrees-of-freedom of a tractor semi-trailer tank model. ...

Abstract—A vehicle will usually become unstable while it is turned on a low friction road or in high speeds because the lateral force of the tire reaches the physical limit. A direct yaw moment control (DYC) can control vehicle motion by a yaw moment which is actively generated by transversally distributed tire longitudinal forces, and has become one of the most promising means of chassis contr...

This paper presents an analysis of the stability of an electric vehicle equipped with in-wheel motors of permanent-magnet type during a class of electrical faults. Due to the constant excitation from the permanent magnets, the output torque from a faulted wheel cannot easily be removed if an inverter shuts down, which directly affects the vehicle stability. In this paper, the impact of an elect...

Accurate measurements from sensors measuring the vehicle’s lateral behavior are vital in todays vehicle dynamic control systems such as the Electronic Stability Program (ESP). This thesis concerns accurate plausibilisation of two of these sensors, namely the yaw rate sensor and the lateral acceleration sensor. The estimation is based on Kalman filtering and culminates in the use of a 2 degree-o...

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 ...
