When designing a vehicle, the most important variable that should be taken into account is vehicle yaw rate, it represents an indication of vehicle’s stability and control. This paper aims to demonstrate how simulate control rate using two methods, first Linear Quadratic method (LQR) other one neural network The classical single-track model prominently used for analysis. One driving conditions ...

Fully electric vehicles with individually controlled drivetrains can provide a high degree of drivability and vehicle safety, all while increasing the cornering limit and the ‘fun-todrive’ aspect. This paper investigates a new approach on how sideslip control can be integrated into a continuously active yaw rate controller to extend the limit of stable vehicle cornering and to allow sustained h...

The need for micromechanical inertial sensors is increasing in future electronic stability control (ESC) and other positioning, navigation and guidance systems. Due to the rising density of sensors in automotive and consumer devices the goal is not only to get high performance, robustness and smaller package sizes, but also to optimize the energy management of the overall sensor system. This pa...

This work is concerned with modeling and control of a vehicle which is assumed to be a body with four wheels. The available control is the vector of torque on the wheels. The aim of the paper is to design a control of the vehicle yaw rate in cornering motions at specified longitudinal speed and steering angle. This problem is one aspect of those appearing in the need of safer, more drivable, an...

This paper shows roll and pitch feedback control on a coaxial mini helicopter equipped with a center of gravity steering mechanism. The helicopter carries a minimal set of sensors to measure yaw rate, distance to ground and roll and pitch angle. While yaw rate and distance to ground control are already realized on the helicopter, roll and pitch control including the necessary signal filtering a...

Many active safety systems in automotive vehicles, for instance yaw stability systems such as ESC/ESP, depend on information about vehicle velocity, in particular lateral velocity or side-slip angle, to be able to function properly. However, the vehicle velocity is rarely measured directly due to issues of cost and reliability, and must therefore in general be inferred from other measurements, ...

This paper proposes an estimation method for ships on collision courses taking crash astern maneuvers based on a new potential area of water (PAW) for maneuvering. A crash astern maneuver is an emergency option a ship can take when exposed to the risk of a collision with other ships that have lost control. However, lateral forces and yaw moments exerted by the reversing propelle...

An optimal reconfiguration control scheme based on control allocation CA is proposed to stabilize the yaw dynamics of the tractor-semitrailer vehicle. The proposed control scheme is a twolevel structure consisting of an upper level of sliding mode yaw moment controller SMYC and a lower optimal brake force distributor BFD . The upper SMYC is designed to follow the tractor yaw rate and the combin...
