By analyzing the key safety problems under the front-outside-tire burst steering condition, a vehicle stability control strategy is proposed in this paper, which is based on active front steering and differential braking systems. Taken both the handling stability and safety into account, we divided the whole control strategy into two layers, which are yaw moment control layer and the additional steering angle & tire force distribution layer. To solve the similar linear problem concisely, the LQR control is adopted in the yaw moment control layer. To achieve the goal of providing enough additional lateral force and yaw moment while keeping the burst tire in appropriate condition, the additional steering angle provided by active front steering system and the tire force distribution was adjusted step by step. To test the proposed control strategy performance, we modelling a basic front-outside-tire burst steering condition, in which the tire blows out once the vertical pressure reach the predefined critical value. Through simulation on different adhesion coefficient road, the control strategy proposed in this paper performance quite better compare with the uncontrolled one in aspect of movement, burst tire protection, handling stability.

The steering radius and the vehicle velocity is utilized to control the drive force and steering angle of each electric-wheel in this essay. In order to improve the characteristics of vehicle, a dynamic simulation was made with the predictions of constant velocity and radius to the vehicle model with the R-v control strategy. This simulation proves that the characteristics of vehicle steering will be better with the utilization of this control strategy.

Because there are several axles in multi-axle vehicle, steering controlling is very complex. It is proposed to use the front wheel steering angle and D as input controlling variables, and to realize centroid sideslip angle control. A five-axle vehicle model was built with ADAMS software, and the control strategy was built with Simulink software. The steering angle step response simulations were processed, such as only font wheels steering, fixed D value steering, and different sideslip angle control strategy. It is found that for only font wheels steering test, variable sideslip angle control strategy could make the overshoot of yaw rate reduce from 98% to 10%, convergence time reduce to 57%.

This paper presents the preliminary studies of the control strategy based in fuzzy logic, projected for the steering system of AGRIBOT project that consist of a wheeled autonomous mobile robotic in real scale endowed with four independent steering and driven wheels (4WSD). In this work we present a preliminary fuzzy controller design applied to front steering angle, using a multivariable plant which incorporates simplified linear model of lateral dynamics of a vehicle whose input are linear combination of rear and front steering angles. The fuzzy control strategy was decided because provides flexible way to deploy with embedded systems. Simulations are used to illustrate the designed controller performance. We use Ackerman geometry to trace front steering angle that allows the vehicle to perform correctly a given maneuver preserving a minimum level of stability and maneuverability. The goal is to establish a relationship between steering input commands and the control commands to the actuators so that it is possible to adjust the attitude of the actuators over the movement axis, as the trajectory change.

This paper considers the problem of trajectory deviating for a class of roboticized roadheader. The motion model of roadheader is first established based on the analysis of excavation construction procedure, then the fuzzy control strategy based on dual-modality structure is proposed to realize directional adjustment and forward-walking control. The relationship between steering angle and driving wheel speed and the establishment of fuzzy control model are mainly focused. The experiment results indicate that the control strategy can satisfy the requirements of excavation construction procedure, and the remote control of roadheader can also be conducted. It is shown that the proposed approach can take an important role in few or unattended roadheader working face construction.

This study aims the development of a control strategy of steer-by-wire automotive with joystick. This control strategy makes driver able to change or maintain the steering angle of road wheels of the vehicle by joystick, provides feedback force to the driver and offers variable steering ratio, variable force feedback and proper damping. The control strategy was mathematically modeled and implemented using the simulation tool Matlab/Simulink and tested to inspect its effectiveness. The result of the test proves the control strategy is effective and the performance of a joystick steering system can be comparable to a traditional steering wheel by applying this control strategy, indicating potential possibility of joystick-steered automotive.

The multi-vehicle combined transportation of large-scale equipment or goods is studied, and various combined transportation modes are obtained. The research on four-vehicle combined transportation is studied, the four transport vehicles must ensure synchronization in the process of running, and the steering must be coordinated, otherwise major accidents may occur. Aiming at the stability control of multi-vehicle running synchronization, the system transfer function of pump-controlled motor in driving system is established, and the PID control is added. The simulation results show that adding the PID control algorithm can improve the speed stability of the transport vehicle. And the geometric model of the steering mechanism is established, the functional relationship between the steering angle and the stroke of the steering cylinder is obtained, and the relationship between the electric signal of proportional valve and the steering angle is deduced. On this basis, the coordinated control system of four-vehicle running synchronization and steering coordination based on CAN (controller area network) bus is designed. The master-slave synchronization control strategy and the PID control are applied to the four-vehicle combined transportation. According to the data collected from the test, it is proved that the control strategy fully meets the transportation requirements, and can provide theoretical basis and design method reference for the safe and reliable combined transportation of various types of transport vehicles.
