Robust Fuzzy-Optimal Four Wheels Steering Nonlinear Controller
IFAC Proceedings Volumes, 2002Abstract Nonlinear single track vehicle model is investigated. The nonlinearity in the vehicle model reduces vehicle stability significantly. Four wheel steering nonlinear controller is developed to utilize the responsiveness and relaxed stability of the rear wheel steering in conjunction with front wheel steering using fuzzy logic robust controller ...

Simulation Analysis Of Vehicle Four-Wheel Steering Control
International Journal Of Scientific Advances, 2023In order to study the handling stability of four-wheel steering vehicle, the vehicle is simplified into a linear two-degree-of-freedom model. The fuzzy control technology is used to study the proportional feedforward + fuzzy feedback control strategy of four-wheel steering vehicle, and the fuzzy control toolbox in Matlab/Simulink is used to establish ...

Four Wheel Steering System for Medium-Duty Trucks
SAE Technical Paper Series, 1994<div class="htmlview paragraph">From the standpoint of safety, the demands are growing in recent years for better controllability and stability of automobiles and in particular in trucks. The truck, however, when compared with the passenger car, is subject to larger changes in gross vehicle mass and center of gravity depending on its load ...

Automatic guidance of a four-wheel steering vehicle
2008This paper is aimed to present the development of an automatic guidance system dedicated to a four-wheel steering vehicle. The attractive feature is that, despite of sliding phenomena, both lateral and angular deviations can be explicitly controlled with respect to the path to be followed. This is particularly useful to compensate the crabway motion on

Four Wheel Steering Advantageous for the Autodriver Algorithm
2014The autodriver algorithm was originally developed based on the dynamics of 4-Wheel-Steering (4WS) vehicles. The algorithm was transformed to be usable on 2WS vehicles which is more practical based on the existing steering systems for the vehicles on roads. The kinematic advantage of 4WS for the autodriver algorithm is presented.

Four-wheel steering control system
2013A four-wheel steering control system includes: a torque sensor (10) that detects a steering torque based on an operation of a steering member (2); a steering angle sensor (4) that detects a steering angle; a steering assist control unit (31) that calculates an assist force for steering front wheels based on the value detected by the torque sensor (10);
